RESUMO
The cluster frontline demonstrations (CFLDs) on Rajmash and Greengram were conducted by Krishi Vigyan Kendra, Kupwara, J&K at farmers’ fields during the year 2021. Through farmer meetings and group discussions, the crucial inputs in the production technology were identified. The results for Rajmash and Greengram showed that overall yield trends of demonstrations varied from 7.00 q/ha to 11 q/ha and 6.00 q/ha to 9.00 q/ha, respectively, with yield increase of 57.14% and 50% over the yield of local practices. Due to significant heterogeneity in the extent of adoption of recommended technology based on the level of risk associated in terms of cost,convenience, skill, and information regarding the concerned practise, the yield levels were much lower under local practices. Rajmash and greengram's average extension gap, technology gap, and technology index, respectively, were found to be 4.00, 1.00 q/ha and 8.33 percent and 3.00, 1 q/ha and 10.00 percent. The demonstration's average gross and net returns for the rajmash and greengram crops, respectively, were 44.44 and 145.33 percent, 70.00 and 289.55 percent greater than the farmer’s practices. In rajmash and greengram, the average benefit-cost ratio was higher with 44 and 145 percent respectively. Variations in agro-climatic factors, soil fertility, biotic stresses, economic status, and management practices were found to cause variations in the technology gap and index percentage. By encouraging farmers to use sustainable technical practices for increasing the yield and productivity of pulse crops, this variation can be reduced. With the application of pesticide, the performance of enhanced technology was shown to be most successful in controlling the smallest number of afflicted plants/m2 as well as the smallest number of pods/plants. Under demonstrations, production was higher than local practice. In order to increase the area and production of pulses in the Kupwara District of Jammu and Kashmir, pulse production and protection technology has a wide range of potential applications.
RESUMO
Total pulses area in Uttar Pradesh, contributes of pulses through the Bundelkhand region, more than half but the productivity is low because lack of technological approaches for pulse growing area. This review paper assessed the cultivation of pulses production, productivity and area, of Bundelkhand and in India also. The technologies and infrastructure need to be accepted pulses cultivation and accurate policies for the farmers through government. Pulses are next to cereals regarding their nutritional and economic significance to human health. The pulses crop highly water sensitive like chickpea, lentil, mung bean and black gram are dominant in drought prone areas and improve soil fertility by fixing atmospheric nitrogen. Rainfed Agriculture has emerged as an opportunity in raising pulse production which is depend on amount and distribution of rainfall growing area. The cropping system of pulses cultivation year-after-year has observed that incidence of disease, insect-pests and weeds increase in Bundelkhand region. In pigeon pea, chickpea and lentil crops, important biotic agent for affecting production. United Nations declared 2016 ' "International Year of Pulses" was to increase production and consumption of pulses 10% by 2025 and raise public awareness towards health through social media. The many initiatives schemes govern by government of India for increase the pulses growing area and production such as ISOPOM (Integrated Scheme of Oilseeds, Pulses, Oil palm and Maize) (2004-05 to 2009-10), NFSM Pulses (National Food Security Mission, 2007-08), for Technology demonstration. The Bundelkhand regions as 5 lakhs farmers of 14 districts of two states of Madhya Pradesh and Uttar Pradesh should be linked with Rani Lakshmi Bai Central Agricultural University (RLBCAU) and benefited from this university to produce pulses.
RESUMO
A field experiment was conducted at the College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) to study the effect of pearl millet (Pennisetum glaucum L.) - pulses intercropping system and nutrient management on growth and yield of pearl millet during summer season of the years 2021 and 2022. The experiment was laid out in a split plot design consisting 24 treatment combinations replicated thrice. The main plot treatments comprised of four intercropping system viz., sole pearl millet (I1), pearl millet + greengram (I2), pearl millet + blackgram (I3), pearl millet + cowpea (I4) and six nutrient management practices in sub plot viz. control (F1), 100% RDF to pearl millet through inorganic fertilizer (F2), 5 t/ha FYM + 100% RDF through inorganic fertilizer (F3), 5 t/ha FYM + 100% RDF through inorganic fertilizer on base of STV (F4), 25% RDN through FYM + 75% RDF through inorganic fertilizer (F5) and 50% RDN through FYM + 50% RDF through inorganic fertilizer (F6). Among main plot effect, significantly higher dry matter accumulation per plant, number of effective tillers per plant, earhead length, earhead weight, grain weight per earhead, grain and straw yields of pearl millet were noted in sole pearl millet (I1) during both the years of investigation as well as in pooled analysis. Whereas plant height and pearl millet equivalent yield was significantly higher in pearl millet + greengram (I2) intercropping system. In case of sub plot nutrient management practices, significantly higher values of plant height, dry matter accumulation per plant, number of effective tillers per plant, earhead length, earhead weight, grain weight per earhead, grain and straw yields as well as pearl millet equivalent yield were recorded in F4 (5 t/ha FYM + RDF through inorganic fertilizer on base of STV) which remained statistically at par with treatment F3 (5 t/ha FYM + 100% RDF through inorganic fertilizer) treatment. Interaction effect of I1F4 (sole pearl millet along with 5 t/ha FYM + RDF through inorganic fertilizer on base of STV) resulted in significantly higher dry matter accumulation per plant at 60 DAS and harvest, earhead weight, grain weight per earhead, grain and straw yield of pearl millet.
RESUMO
A field experiment was conducted in rabi seasons (2022) at Karunya Institute of Technology and Sciences, Coimbatore to study the maize-based intercropping with different legumes under rainfed condition as there are less research work regarding intercropping of maize in this area. Greengram (Vigna radiata), cowpea (Vigna unguiculata) and horsegram (Macrotyloma uniflorum) were selected as intercrops in 4:1 and 6:1 row ratio. The result of the study indicated that intercropping of greengram and cowpea with maize (Zea mays L.) in 4:1 gave higher total grain yield and stover yield compared to the sole cropping of maize under rainfed condition. Other intercropping indices like grain equivalent yield, land equivalent ratio, relative crowding coefficient, competition index and income equivalent ratio were calculated. Intercropping system of maize + greengram (4:1) recorded the higher net return and B: C ratio followed by it maize+ cowpea (4:1). Therefore, under rainfed conditions of western zone of Tamil Nadu, maize + greengram 4:1 intercropping system may be suggested to get greater net return and B: C ratio.
RESUMO
Front-Line Demonstration (FLD) is a long-term educational activity carried out systematically by agricultural experts in the field of farmers to demonstrate the value of new practices/technologies in the micro-agriculture situation. The aim of the FLD was to demonstrate improved pulses technologies for production potential. Improved technologies include the use of improved varieties, seed treatment with Rhizobium and PSB culture, sowing methods, balanced fertilizer application and improved pest control techniques. The results of pulses harvested crop in 2021-2022 showed that improved varieties with improved practice packages recorded a higher yield compared to farmers’ practices. The improved technologies saw yield increases of 26.33 %, 24.63 %, 23.41 % and 22.83 % yield increase over farmer practices in green gram, chick pea, pigeon pea and black gram respectively. The average percentage yield increased by 24.30 % over farmers’ practices. The mean technological yield gap was highest for chickpea (3.47 q/ha), followed by pigeon pea (1.36 q/ha), green gram (1.34 q/ha) and black gram (1.26 q/ha). The maximum mean extension yield gap in the study was recorded in pigeon pea at 11.83 q/ha followed by black gram (5.22 q/ha) and green gram (3.57 q/ha), while the lowest extension yield gap was observed in chickpea (2.44 q/ha). The technology index varied between 7.16 and 17.35% while the lowest (7.16) was recorded for pigeon pea. The highest gross return (Rs. 81,654/ha), net return (Rs. 56,370/ha) and benefit-to-cost ratio (3.23) was recorded with chickpea demonstration followed by Black gram and green gram while lowest gross return (Rs. 44,848/ha), net return (Rs.24,634 /ha) and benefit cost ratio (2.22), which was markedly higher than gross return (Rs. 36,342/ha), net return (Rs.16,430/ha) and benefit cost ratio (1.83) in farmers practice. The improved technologies yielded a higher gross return and, net return with a higher benefit-to-cost ratio than farmers’ practices.
RESUMO
Field experiments were conducted at the South farm in Karunya Institute of Technology and Sciences, Division of Agronomy, Coimbatore, during the Rabi season of 2022. The experimental site is situated in the western agro-climatic zone of Tamil Nadu, at a latitude of 10°56'N and longitude of 76°44'E, with an elevation of 474 meters above mean sea level. The soil composition of the experimental field was identified as clay loam, moderately drained, and exhibited low availability of nitrogen (202 kg/ha), high availability of phosphorus (12.3 kg/ha), medium availability of potassium (415 kg/ha), and organic carbon content of 0.51%. The experiment followed a randomized block design (RBD) with 10 treatment groups, each replicated three times viz.,T1 - Control, T2 - Vermicompost 100% (on N Equivalent basis)+ Cowdung slurry, T3 -Vermicompost100% (on N Equivalent basis)+TNAU Biomineralizer,T4 -Vermicompost100% (on N Equivalent basis) + (Effective microorganism),T5 - Vermicompost 100% (on N Equivalent basis) + Pleurotus sp + Urea, T6- Vermicompost (50%) +RDF (50%) + Cowdung slurry, T7- Vermicompost (50%) +RDF (50%) + TNAU Biomineralizer, T8 -Vermicompost (50%) + RDF (50%) + EM (Effective Microorganism),T9 -Vermicompost (50%) + RDF (50%) + Pleurotus sp ,T10 - RDF alone. The objective of the study was to investigate the impact of vermicompost and other foliar applications on the growth, physiological characteristics, and yield parameters of an irrigated Black gram (VBN8 variety). The promotion of yield can be attributed to the increased vegetative growth and the balanced carbon-to-nitrogen (C: N) ratio, which likely stimulated the synthesis of carbohydrates. This, in turn, facilitated the overall improvement in seed yield. The application of RDF played a significant role in enhancing growth, leading to various positive changes in yield-related characteristics. Ultimately, the increased seed yield observed can be largely attributed to the improved plant growth and subsequent positive effects on yield-related attributes resulting from the RDF application. Thus, From this Experiment it was Concluded that the RDF (T10) Shows a highest range in growth, physiological and yield parameters of irrigated Blackgram due.
RESUMO
Seed Production of rice fallow blackgram variety, ADT3 has limitations due to inherent issues of soil fertility, climate change and thermo sensitivity results in poor flowering, reduced pod setting and poor seed filling. Macro and micro nutrients application during critical stages of growth were tried to improve the seed yield and quality in rice fallow blackgram variety ADT3. The combined foliar spraying of 0.5% NPK (macro) and 0.2% chelated micro nutrients mixture (Fe 2.5%, Mn 1.0%, Zn 3.0%, Cu 1.0%, Mo 0.1% and B 0.5%), were sprayed on 15th (Vegetative phase), 30th (Reproductive phase), 45th ( Flowering and pod formation phase) days after germination improved the growth and seed parameters viz., plant height, number of branches, number of pods per plant, number of seeds per pod, filled seed % which resulted in increased seed yield in rice fallow blackgram variety, ADT3.Response of macro and micro nutrients through foliar mode revealed the lack of soil fertility resulting in poor uptake of macro and micro nutrients. Foliar application induced uniform flowering and synchronous maturity of pods with least shattering which would facilitate mechanical harvesting. Foliar application of macro and micro nutrients phenotypically altered the source-sink which greatly influenced the yield of seed, germination and seedling quality parameters
RESUMO
Currently, commercial devices for electrical neural stimulations can only provide fixed stimulation paradigms with preset constant parameters, while the development of new stimulation paradigms with time-varying parameters has emerged as one of the important research directions for expanding clinical applications. To facilitate the performance of electrical stimulation paradigms with time-varying parameters in animal experiments, the present study developed a well-integrated stimulation system to output various pulse sequences by designing a LabVIEW software to control a general data acquisition card and an electrical stimulus isolator. The system was able to generate pulse sequences with inter-pulse-intervals (IPI) randomly varying in real time with specific distributions such as uniform distribution, normal distribution, gamma distribution and Poisson distribution. It was also able to generate pulse sequences with arbitrary time-varying IPIs. In addition, the pulse parameters, including pulse amplitude, pulse width, interphase delay of biphasic pulse and duration of pulse sequence, were adjustable. The results of performance tests of the stimulation system showed that the errors of the parameters of pulse sequences output by the system were all less than 1%. By utilizing the stimulation system, pulse sequences with IPI randomly varying in the range of 5~10 ms were generated and applied in rat hippocampal regions for animal experiments. The experimental results showed that, even with a same mean pulse frequency of ~130 Hz, for neuronal populations, the excitatory effect of stimulations with randomly varying IPIs was significantly greater than the effect of stimulations with fixed IPIs. In conclusion, the stimulation system designed here may provide a useful tool for the researches and the development of new paradigms of neural electrical stimulations.

Global demand for pulses such as the mung bean has grown in the last years. For successful production of these crops it is necessary to use high quality seeds. Methodologies based on X-ray image analysis have been used as a complementary tool to evaluate the physical quality of seeds due to their speed and potential for automation. The aim of this study was to evaluate the efficiency of X-ray analysis for non-destructive evaluation of the physical quality of Vigna radiata seeds and to relate the variables obtained with their physiological potential. For this, seeds from eight lots were X-rayed and subsequently subject to germination test. In total, 18 physical and physiological parameters were determined. The X-ray image analysis was efficient for evaluating the internal morphology of Vigna radiata seeds and allowed the identification of various damage types. However, it was not possible to relate the physical variables to the seed quality as the lots presented similar germination percentage. Physical variables such as solidity and circularity are related to percentage of root protrusion and length of seedling hypocotyl. Low relative densities indicate deteriorated tissues, related to severe morphological damage and non-viable seeds.
A demanda mundial por leguminosas como o feijão mungo tem crescido nos últimos anos. Para o sucesso da produção destas culturas é necessário a utilização de sementes de alta qualidade. Metodologias baseadas na análise de imagens de raios X têm sido utilizadas como ferramenta complementar para avaliação da qualidade física de sementes em função da sua rapidez e potencial de automatização. O objetivo deste trabalho foi avaliar a eficiência da análise de raios X para avaliação não destrutiva da qualidade física de sementes de Vigna radiata, e relacionar as variáveis obtidas com o seu potencial fisiológico.Para tal, sementes de oito lotes foram radiografadas e submetidas ao teste de germinação. Por meio dessas avaliações foram determinadas 18 variáveis, distribuídas entre físicas e fisiológicas. A análise de imagens de raios X foi eficiente para a avaliação da morfologia interna das sementes Vigna radiata e permitiu a identificação de vários tipos de danos. Porém, não foi possível relacionar as variáveis físicas com a qualidade das sementes, pois os lotes apresentaram porcentagens de germinação semelhantes. Variáveis físicas como solidez e circularidade estão relacionadas com a percentagem de protrusão radicular e o comprimento de hipocótilo das plântulas. Densidades relativas baixas indicam tecidos deteriorados, tendo relação com danos morfológicos graves e sementes inviáveis.

Pulses are one of the cheapest sources for the extraction of protein concentrates which can be gainfully utilized for meeting protein needs of specific groups. Techniques for maximum extraction of Pulse protein concentrates were developed for red gram and Bengal gram by standardisation of process parameters involving alkaline extraction followed by isoelectric precipitation. Extraction conditions viz., flour: water ratio – 1:10, pH 9 and stirring time- 4 hours were employed for isolation of the pulse protein concentrates. The protein concentrates extracted from red gram and chickpea were incorporated in ice cream formulations at concentrations of 5 and 10%. The pulse protein concentrate incorporated ice cream at 5% level had a higher sensory score of 8.7 and 8.8 on the nine-point hedonic scale compared to ice cream enriched with 10% pulse protein concentrate (8.4 and 8.5/9.0). The pulse protein enriched ice cream had a high protein content of 11.76 g/100 g compared to 4.90 g/100 g in control. Pulse protein concentrates have a wide food application in designing speciality foods for different age groups and disease conditions. The PPC incorporated protein enriched ice cream would provide for nutritious ice cream having desirable sensory properties with commercialisation prospects.
RESUMO
Objective To explore the impact of different angles between blood vessels and acoustic axis in the target area on pulse high intensity focused ultrasound (PHIFU) peripheral ablation.Methods Thirty New Zealand rabbits were selected,and the thoracic aortas were obtained.Models of tissue mimicking material were used via embedding the rabbit thoracic aorta into the center of the target barrier area.Then the models were divided into 0°,45° and 90° groups according to the angles with the acoustic axis,and the control group was set up as well (each n =10).Under B-ultrasound monitoring,PHIFU peripheral ablation was performed with the same parameters in each group.The temperature was measured during ablation.After ablation,the models were cut step by step for macroscopic and ultrasound observation.The total volumes (V) were calculated and compared,and the target blood vessels were sampled for pathological examination.Results The peripheral region in control group showed strong echo on ultrasound image,while in 0°,45° and 90° group the blood vessels showed low echo accordingly.The maximal temperatures in control group,0°,45° and 90° group was (98.60 ± 5.76) ℃,(98.90 ± 7.09) ℃,(71.10 ± 13.85) ℃ and (70.20 ± 9.14) ℃,respectively.Statisticaldifference was found between control group and 45°,90° group (all P＜0.05).The total volume in control group,0°,45° and 90° group was (40 709.70 ± 3 193.31) mm3,(40 029.02 ± 3 580.17) mm3,(34 562.59 ± 3 883.26) mm3 and (36 737.01± 3 278.68)mm3,respectively,while no statistical difference was found between control group and 0° group (P＞0.05).Pathological examination showed that the elastic fibers fractured partly,and disruption of cell nucleus were observed in 45° and 90° group.Conclusion When the angle between the blood vessel and acoustic axis is 0°,its impact on energy deposition is minimally,while the destruction of the vascular wall becomes stronger when the angle is 45°and 90°.
RESUMO
Aiming at many questions nowadays in the study on the theory of syndrome differentiation and treatment with acupuncture and moxibustion, the relevant rules and important theoretic issues were discussed on the syndrome differentiation and treatment with acupuncture and moxibustion in the paper from the multidimensional perspectives, named the treatment in view ofdifferentiation-pulse-based acupuncture, the treatment in view of meridian-collateral () differentiation, the treatment in view of body differentiation, the treatment in view of "four seas" differentiation, etc. It is proposed that the complicated multidimensional relationships of human body determine the multi-perspectives and multi-angles in the syndrome differentiation and treatment with acupuncture and moxibustion, in which, the theoretic principle of every approach to the syndrome differentiation and treatment has its relatively independent significance. Regarding the new study recognition, it is suggested that the pulse-based acupuncture ofdifferentiation according to the comparison between theand thepulse conditions works on the positive regulation of() balance with acupuncture. Additionally, in the paper, the origins of five thoughts are put forward on the differentiation and treatment on the basis of meridians and collaterals, which enriches the connotation of this approach to the differentiation and treatment; the "five-tissue" effects and "five-" effects are innovated and the theory is proposed originally on the "four seas" differentiation and treatment, etc.
RESUMO
With the objective of finding fluctuations on fish body condition in the Middle Paraná River floodplain in different hydrological scenarios, this attribute was analyzed in several trophic groups of a secondary floodplain channel and its associated lakes between 2010 and 2012. Standardized residuals generated by length-weight regressions were calculated for each species and the relative weight (Wr) of the most abundant species per group was examined. A two-way factorial ANOVA was carried out (factors: hydrology and habitats) to evaluate the existence of significant spatial-temporal differences by groups and species. Results showed that body condition in detritivorous, herbivorous and omnivorous species fluctuated significantly depending on hydrology and the environment. Optimal body condition was recorded after the largest flood pulse in most species. Body condition decreased during the low-water period and after two disconnection periods, whereas during the second flood pulse it increased in detritivores, herbivores and omnivores. No floods occurred thereafter, but two flow pulses were registered, and body condition increased under these hydrologic scenarios, with similar or higher values to those recorded after the largest pulse. These results indicate that flow pulses, which are supplementary to flood pulses, may have a positive effect on fish body condition.(AU)
Con el objetivo de conocer la fluctuación de la condición corporal de peces en la planicie de inundación del tramo medio del río Paraná ante diferentes escenarios hidrológicos, se analizó este atributo de diferentes grupos tróficos en un cauce secundario de la planicie y sus lagunas asociadas durante 2010 a 2012. Se calcularon los residuos estandarizados generados por las regresiones longitud-peso para cada especie y se examinó el peso relativo (Wr, por sus siglas en ingles) de las especies más abundantes de cada grupo. Se llevó a cabo un ANOVA factorial de dos vías (factores: hidrología y ambientes) para evaluar la existencia de diferencias significativas espacio-temporales por grupos y por especies. Los resultados mostraron que la condición corporal de las especies detritívoras, herbívoras y omnívoras fluctuó significativamente en función de la hidrología y los ambientes. Óptimas condiciones corporales se registraron en la mayoría de las especies después del mayor pulso de inundación. La condición corporal disminuyó durante el período de aguas bajas y luego de dos períodos de desconexión, mientras que, durante el segundo pulso, aumentó en detritívoros, herbívoros y omnívoros. No hubieron inundaciones luego, pero ocurrieron dos pulsos de flujo y las condiciones corporales se incrementaron bajo estos escenarios hidrológicos, presentando valores similares o incluso mayores a los registrados luego del gran pulso. Esto destaca que los pulsos de flujo complementarios a los pulsos de inundación pueden tener un efecto positivo sobre la condición corporal de peces.(AU)

Lentil, as an economical source of protein, minerals and vitamins, plays important role in nutritional security of the common man. Grown mainly in West Asia, North Africa (WANA) region and South Asia, it suffers from several biotic stresses such as wilt, rust, blight and broomrape. Lentil rust caused by autoecious fungus Uromyces viciae fabae (Pers.) Schroet is a serious lentil disease in Algeria, Bangladesh, Ethiopia, India, Italy, Morocco, Pakistan and Nepal. The disease symptoms are observed during flowering and early podding stages. Rust causes severe yield losses in lentil. It can only be effectively controlled by identifying the resistant source, understanding its inheritance and breeding for host resistance. The obligate parasitic nature of pathogen makes it difficult to maintain the pathogen in culture and to apply it to screen segregating progenies under controlled growth conditions. Hence, the use of molecular markers will compliment in identification of resistant types in different breeding programs. Here, we studied the inheritance of resistance to rust in lentil using F1, F2 and F2:3 from cross PL 8 (susceptible) x L 4149 (resistant) varieties. The phenotyping of lentil population was carried out at Sirmour, India. The result of genetic analysis revealed that a single dominant gene controls rust resistance in lentil genotype L 4149. The F2 population from this cross was used to tag and map the rust resistance gene using SSR and SRAP markers. Markers such as 270 SRAP and 162 SSR were studied for polymorphism and 101 SRAP and 33 SSRs were found to be polymorphic between the parents. Two SRAP and two SSR markers differentiated the resistant and susceptible bulks. SSR marker Gllc 527 was estimated to be linked to rust resistant locus at a distance of 5.9 cM. The Gllc 527 marker can be used for marker assisted selection for rust resistance; however, additional markers closer to rust resistant locus are required. The markers linked to the rust resistance gene can serve as starting points for map-based cloning of the rust resistance gene.
RESUMO
Vigna radiata (Fabaceae) is an important pulse crop widespread throughout the tropics and warm temperature regions. In this study, we evaluated the in vitro anti-inflammatory and in vivo antiarthritic activity of Vigna radiata sprouts in rats. The in vitro anti-inflammatory activity was determined by membrane stabilization and protein denaturation method. Whereas, the antiarthritic activity of the ethanolic extract of the sprouts was evaluated by complete Freund’s adjuvant model with diclofenac sodium as the standard drug. Body weights, paw volume, biochemical parameters such as lipid peroxidation, total reduced glutathione, myeloperoxidase and lysosomal enzymes like cathepsin-D, N-acetyl β-D-glucosamindase and β-D-glucuronidase were estimated. Treatment with ethanolic extract of V. radiata exhibited significant membrane stabilization activity and protein denaturation activity, and significantly attenuated the biochemical changes induced by administration of complete Freund’s adjuvant. The findings of the present study suggest the possible role of Vigna radiata in the therapeutics of arthritis.
RESUMO
OBJECTIVE: To determine whether an optimal blood suppression inversion time (BSP TI) can boost arterial visibility and whether the optimal BSP TI is related to breathing rate (BR) and heart rate (HR) for hypertension subjects in spatial labeling with multiple inversion pulses (SLEEK). MATERIALS AND METHODS: This prospective study included 10 volunteers and 93 consecutive hypertension patients who had undergone SLEEK at 1.5T MRI system. Firstly, suitable BSP TIs for displaying clearly renal artery were determined in 10 volunteers. Secondly, non-contrast enhanced magnetic resonance angiography with the suitable BSP TIs were performed on those hypertension patients. Then, renal artery was evaluated and an optimal BSP TI to increase arterial visibility was determined for each patient. Patients' BRs and HRs were recorded and their relationships with the optimal BSP TI were analyzed. RESULTS: The optimal BSP TI was negatively correlated with BR (r1 = -0.536, P1 < 0.001; and r2 = -0.535, P2 < 0.001) and HR (r1 = -0.432, P1 = 0.001; and r2 = -0.419, P2 = 0.001) for 2 readers (kappa = 0.93). For improving renal arterial visibility, BSP TI = 800 ms could be applied as the optimal BSP TI when the 95% confidence interval were 17-19/min (BR1) and 74-82 bpm (HR1) for reader#1 and 17-19/min (BR2) and 74-83 bpm (HR2) for reader#2; BSP TI = 1100 ms while 14-15/min (BR1, 2) and 71-76 bpm (HR1, 2) for both readers; and BSP TI = 1400 ms when 13-16/min (BR1) and 63-68 bpm (HR1) for reader#1 and 14-15/min (BR2) and 64-70 bpm (HR2) for reader#2. CONCLUSION: In SLEEK, BSP TI is affected by patients' BRs and HRs. Adopting the optimal BSP TI based on BR and HR can improve the renal arterial visibility and consequently the working efficiency.

Há necessidade de se desenvolver sistemas de culturas para região Nordeste, que produzam grandes quantidades de fitomassa, para permanecer por maior tempo na superfície, oferecendo proteção ao solo. O presente trabalho objetivou avaliar a capacidade de produção de fitomassa de diferentes sistemas de culturas e sua influencia na produtividade do milho na microrregião de Guarabira - PB. Foram instalados seis sistemas de culturas: semeadura direta com milho (SD); semeadura direta com milho + mucuna (SDM); semeadura direta com milho + guandu (SDG); semeadura direta com milho + guandu + mucuna (SDGM); semeadura direta com milho + fava (SDF) e semeadura direta com milho + fava + mucuna (SDFM), na presença e ausência de adubação mineral com N-P-K, avaliados durante 9 anos. Foram avaliados o percentual de cobertura e a quantidade de fitomassa sobre o solo, bem como a produtividade de grãos de milho. A adubação mineral e as leguminosas proporcionaram acréscimos variando entre 22% e 49% de produtividade de grãos de milho entre os sistemas de cultivo. Com o passar dos anos, os sistemas de culturas promoveram estoque de fitomassa com acréscimos de até 76% na superfície do solo e, embora a precipitação seja um fator limitante para produção de fitomassa, o uso das leguminosas e da adubação mineral com N-P-K nos sistemas de culturas facilitaram a implantação do sistema de semeadura direta na região estudada.
The major problem of implementation of direct seeding in the Northeast is the phytomass production and accumulation on the soil surface. There is a necessity to develop cropping systems for the Northeast region, which produce large quantities of phytomass, to stay for longer time on the soil surface, providing protection to the soil. This study aimed to evaluate the ability of phytomass production of different cropping systems and its influence on corn yield in the microregion of Guarabira - PB. Six cropping systems were installed: tillage with maize (SD); tillage with corn+velvetbean (SDM); tillage with maize+pigeonpea (SDG); tillage with corn+ velvetbean+pigeonpea (SDGM); tillage with corn+broad bean (SDF); and no tillage with corn+ velvetbean+broad bean (SDFM); with and without NPK fertilizer, were evaluated for 9 years. The percentage of crop cover and the phytomass accumulation on the soil and yield of corn were evaluated. The mineral fertilizer and legumes provided increases ranging between 22% and 49% of corn grain yield among tillage systems. Over the years, crop systems promoted stock biomass with increases of up to 76% on the soil surface, and although the precipitation is a limiting factor for biomass production, the use of legumes and fertilization with NPK mineral systems cultures facilitated the implementation of no-till system in this region.
RESUMO
In this study, we evaluated the influence of various hydrological cycles on the feeding body condition of fish species of different trophic guilds in the Paraná River floodplain, as well as the impacts of upstream impoundments on fish conditions. Attributes of the river floods (duration, time of year, intensity, and variability in a given year) and the body condition, measured by the mean residuals of length-weight ratios, of the detritivorous, herbivorous, insectivorous, invertivores, omnivorous, piscivorous, and planktivorous species were evaluated. Fish were sampled during a period before (1986-1994) and after (2000-2004) the completion of filling of the Porto Primavera Reservoir, which is located upstream from the floodplain area under study. Three sub-basins in the floodplain were sampled: the Ivinheima River, which has no dams; the Paraná River, which has several dams; and the Baia River, which is influenced by the Paraná. A two-way ANOVA identified significant variations in mean body conditions for localities and for the hydrological cycles, and the interactions were also significant. The findings revealed that before the Porto Primavera Reservoir was filled, the body condition of the feeding guilds varied similarly in the three sub basins, but this pattern was not observed after filling was completed. However, in years with minor or no floods, the body condition was high, especially in the sub-basins influenced by Porto Primavera (Paraná and Baía). Pearson's and Spearman's correlations showed that most effects of the floods were unfavorable to the body condition of the guilds, except for the annual variation in water level, which aids herbivores in accessing allochthonous food resources. Detritivores were negatively affected by all flood attributes. A correlation between the relative stomach weight (mean residual of the ratio of total and stomach weights) and the body condition demonstrated the poor relationship between the amount ...
Nesse estudo, buscou-se avaliar a influência de diversos ciclos hidrológicos sobre a condição nutricional de peixes de diferentes categorias tróficas, na planície alagável do alto rio Paraná, bem como dos impactos de represamentos a montante, sobre esse processo. Para isso foram avaliados os atributos das cheias anuais (duração, época, intensidade, variabilidade) e a condição nutricional dos peixes, medida pelos resíduos médios da relação entre o peso e o comprimento de espécies detritívoras, herbívoras, insetívoras, invertívoras, onívoras, piscívoras e planctívoras. Os peixes foram coletados em período anterior (1986-1995) e posterior (2000-2004) ao represamento de Porto Primavera, a montante, em três subsistemas da planície alágável do alto rio Paraná, Ivinheima (sem controle por represamentos), Paraná (com represamentos) e Baía (influenciado pelo rio Paraná). Uma análise de variância (ANOVA bifatorial) revelou variações significantes na condição nutricional média dos peixes, tanto entre subsistemas e ciclos hidrológicos, como em suas interações. Os resultados evidenciaram que antes do represamento, as variações na condição nutricional dos peixes foram similares entre os subsistemas, divergindo no período subseqüente, e que em anos com cheias incipientes ou nulas a condição nutricional foi elevada, especialmente nos subsistemas influenciados pelo represamento a montante. As correlações de Pearson e Spearman revelaram que, pelo menos parte dos atributos das cheias foram adversos para os peixes de diferentes categorias tróficas, exceto a variabilidade anual dos níveis fluviométricos, que possibilitou às espécies herbívoras o acesso periódico a fontes de alimento externas. As espécies detritívoras foram afetadas negativamente por todos os atributos da cheia. As mesmas correlações realizadas entre o peso relativo do estômago (resíduo médio da relação peso do estomago-peso total) e a condição nutricional demonstraram ausência de relação ...

Flood pulses affect floodplain enrichment via the incorporation of nutrients and terrestrial biomass. As a result, they positively affect the body condition of aquatic organisms. This paper evaluates whether the absence of floods (resulting from dam control) affects the feeding activity and body condition of piscivorous fish. In addition, whether piscivores respond similarly to alterations in the flooding regime was assessed. Five piscivorous species were selected (Acestrorhynchus lacustris, Hoplias aff. malabaricus, Plagioscion squamosissimus, Rhaphiodon vulpinus, and Salminus brasiliensis). The fish were captured in four distinct years and in three river subsystems with differentiated water level fluctuations (Ivinheira = not regulated; Baía = regulated by the Paraná River level; Paraná = regulated by dams). Feeding activity and body condition were evaluated using the mean values of the standard residuals generated by regression models between body and stomach weights and standard length and body weight (all log-transformed). Differences among years and subsystems were evaluated via two-way analysis of variance. Pearson and Spearman correlations were performed between flooding attributes (duration, amplitude, timing, and daily variability) and feeding activity and body condition. Feeding activity differed across subsystems, whereas body condition varied across years, depending on the subsystem. Hoplias aff malabaricus (an ambusher adapted to starvation) presented feeding activity independent of the flooding regime and also presented better body condition in times of high water levels. Rhaphidon vulpinus exhibited variations in feeding activity but did not present alterations in body condition. The other species presented poorer body condition in years or subsystems with regular floods. Correlations identified that the duration and timing of floods had negative effects on body condition, whereas amplitude and mean annual water level ...
Os pulsos naturais de cheias são considerados fundamentais para o sucesso no recrutamento de peixes e no enriquecimento das planícies de inundação pela incorporação de nutrientes e biomassa terrestre, atuando positivamente na condição dos organismos aquáticos. O presente trabalho pretende avaliar se a ausência dos pulsos anuais, resultantes do controle por reservatórios hidrelétricos, afeta a atividade alimentar e a condição corporal de peixes piscívoros e se este grupo trófico responde de maneira similar às alterações no regime de cheias. Para isto foram selecionadas cinco espécies: Acestrorhynchus lacustris, Hoplias aff. malabaricus, Plagioscion squamosissimus, Rhaphiodon vulpinus e Salminus brasiliensis, capturadas em quatro anos distintos e em três subsistemas com variações hidrométricas diferenciadas (Ivinheima, não regulado; Baía, influenciado pelo regime hídrico do Rio Paraná, e Rio Paraná, nível regulado por represas). A atividade alimentar e a condição corporal foram avaliados através dos valores médios dos resíduos padronizados, gerados pelas regressões entre os logaritmos do peso total e peso do estômago e peso total e comprimento padrão, respectivamente, sendo as diferenças entre anos e subsistemas avaliadas pela análise de variância fatorial (ANOVA). Correlações de Pearson e Spearman entre os atributos hidrográficos (duração, magnitude, época e variabilidade diária) e a atividade alimentar e condição corporal foram analisadas. A atividade alimentar foi diferente apenas entre os subsistemas, enquanto a condição variou entre os períodos conforme o subsistema. Hoplias aff. malabaricus, emboscadora e adaptada a anorexia, foi a única com atividade alimentar independente do regime de cheias e com melhor condição corporal em períodos de águas altas. R. vulpinus, embora com variações na atividade alimentar, não mostrou alterações na condição. Já, as demais espécies mostraram tendências de baixa condição corporal em períodos ou locais ...
