ABSTRACT
Background: Positive identification of living/ deceased using distinct traits is a cornerstone of forensic science. According to Locard’s principle “When two objects come into contact, there is always transfer of material from one to another”. The finger prints, lip prints and blood remains are the evidence for forensic identification. Aim: To study the frequency, distribution and association of ABO blood groups, finger print pattern, lip print pattern among gender and also the inherent nature of patterns among family members. Materials and Methods: A total of 200 Subjects (100 males, 100 females) within the age range of 17- 30 years and 20 families were randomly selected and aggregated as groups. Lip prints and finger prints were collected using dusting technique with fine carbon powder. ABO blood group was determined by slide agglutination method. Results: Ulnar loop - Males - Vertical, Radial loop - Males - Branching, Whorl - Females - Branching, Arch - Males - Intersecting; Females - Vertical. O positive, B positive - Loop - Branching, A positive - Loop - Vertical and Intersecting, AB positive - Whorl - Branching and Intersecting. Among 20 families, 14 families showed 100 percent pattern resemblance. High percentage of similar pattern was observed between father to daughter (70%) in finger prints and mother to son in lip prints (71%). Conclusion: Correlating the uniqueness of these physical evidence helps in personal identification as it can narrow the search & to substantiate the facts where there is little evidence
ABSTRACT
Background: Reports have shown that consumption of acha (Digitaria exilis) is beneficial to both diabetic and hypertensive patients considering its low glycaemic index, if fortified could assist to improve health and in combating hidden hunger. Aims: This work was aimed at establishing the technology of fortifying acha (Digitaria exilis) grains with vitamin A, Iron, copper and zinc by comparing the effectiveness of coating and dusting technologies and analysing the vitamin A, iron, zinc and copper levels of acha grains fortified by both methods. Methodology: Vitamin A was quantified by High Performance Liquid Chromatography (HPLC) method, while iron, zinc and copper were quantified using Atomic Absorption Spectroscopy (AAS) method. Results: Vitamin A was undetected in unfortified grain, but present at 29,904.18 IU/kg and 29,657.66 IU/kg in coated and dusted grains respectively. The iron content(58 mg/kg) in unfortified grain increased by 22% and 15% for coated and dusted respectively, Copper increased by 25% and 14% and Zinc by 32% and 45% with coating and dusting respectively. Conclusion: This study suggests that coating is a more promising technology for fortifying acha grains with Vitamin A, iron and copper, which will assist in delivering these critical micronutrients in the vulnerable population and also be used as a strategy for dietary improvement.
ABSTRACT
Objective@#To analyze the prevalence of pneumoconiosis in Yichang City from 2006 to 2016, and to provide a scientific basis for the administrative department to formulate prevention and control strategies for pneumoconiosis.@*Methods@#From 2006 to 2016, through the China Disease Control Information System Occupational Disease and Occupational Health Inspection System, relevant data were obtained, and the types of pneumoconiosis, the disease area and the dust-collecting age in Yichang City were statistically analyzed.@*Results@#There were 1494 cases of pneumoconiosis in Yichang City, which were mainly distributed in 1 076 cases (72.02%) of coal workers’ pneumoconiosis and 382 cases (25.57%) of silicosis, which occurred in Yiling District, Changyang County, Yidu City and Zigui County. The average age of dust collection was 13.78 years, and the age of onset was mainly concentrated in 5~9 years (35.27%) and 10~19 years (30.32%) . The incidence and severity of pneumoconiosis (phase) were related to the age of dusting (P<0.01) .@*Conclusion@#The pneumoconiosis in Yichang City is mainly concentrated in the mining industry. The types of pneumoconiosis are mainly coal workers’ pneumoconiosis. The occupational health and health management of key industries, regions and types of work should be strengthened.
ABSTRACT
Objective To evaluate the effect of the fast control scheme of schistosomiasis.Methods The fast control scheme of schistosomiasis was carried out,and the scheme mainly included dusting molluscicide,rapid immunodiagnosis screening and chemotherapy with praziquantel,environment modification,health education,etc.The control effects of the scheme were observed longitudinally.Results There were no infected snails found after the scheme was implemented from 2005 to 2008.The densities of living snails dropped from 1.48 snails/0.1 m~2 in 2004 to 0.71 snails/0.1 m~2 in 2008.The areas with snails dropped from 43.13 hm~2 in 2004 to 33.68 hm~2 in 2008.The infection rates of residents and cattle dropped to 0 in 2008.Conclusion The fast control scheme of schistosomiasis can control schistosomiasis fast.
ABSTRACT
Objective To study a new method and technical specification for Oncomelania snail control in irrigation canals.Methods Four percent niclosamide ethanolamine salt dustable powder was dusted in a test canal three times continuously,and a control canal was set up at the same time.The molluscicidal frequency and effect of niclosamide ethanolamine salt powder was observed and the results,including the change of living snail frames,average density of living snails and mortality of snails,were analyzed.Results Between the third and fifteenth day after the first dusting in the test canal,the reduction rate of the density of snails was more than 90% and after the second and third dusting,the reduction rate was more than 99%.For the average rates of living snail frames and mortality of snails,there were significant differences between the first dusting and later two dustings,while there was no significant difference between the second dusting and the third dusting.On the thirtieth and ninetieth day after the third dusting,the effect of snail control was still satisfactory.There were significant differences between the test canal and control canal about all the observation indexes.Conclusion The application of 4% niclosamide ethanolamine salt dustable powder is efficient in the snail control in irrigation canals,and the suitable frequency of dusting is 2 or 3 times.
ABSTRACT
Objective To evaluate the molluscicidal effect and the using value of qiangluocide powder by dusting in the fields. Methods The two different ways of dusting with qiangluocide and spraying with luomiecide for controlling snails were compared in the fields, and the cost-effectiveness was analysed. Results The corrected mortalities and the reduced rates for density of snails were 88.48%, 96.26%, 96.96%, 95.67%, and 87.58%, 95.40%, 96.14%, 96.67%, respectively, on the marshland in Longtan, Nanjing, 73. 65% , 98. 31% , 99. 22% , 99. 26% and 69. 30% , 98.14%, 98.84%, 98. 60% , respectively, on the marshland in Yizheng, Yangzhou, on 1 d, 3d, 7 d, 15 d after dusting with qiangliocide power; and those on 1d, 3d, 7d, 15d after the spraying with luomiecide were 69.15%, 88.01%, 86.46%, 85.56% and 75.27%, 84.99%, 87.50%, 87.96% on the marshland in Longtan, Nanjing, 18.70%, 63.11%, 1.25%, 12.60% and 34. 88% , 89. 02% , 45.37% , 46. 59% , respectively, on the marshland in Yizheng, Yangzhou. The st of dusting with qiangluocide powder was 0. 20 yuan/m2, and that of spraying with luomiecide as 0. 21 yuan/m2 for snail control in the fields. The costs of reduced one percentage for the cor rected mortalities and the density of snail were 6. 27-10. 07 yuan and 6. 21-10. 14 yuan, respectively, on 15 d after dusting with qiangluocide power and those on 15 d after spraying with luomiecide were 7. 36-83. 33 yuan and 7. 16-22. 54 yuan , respectively. Conclusion The dusting with qiangluocide powder is a promising new formulation, which is suitable for the areas without water resource and possessed of high effectiveness against snails. The method ofdusting with qian-gluocide powder for controlling snails is simple, convenient, cheap and easy to be carried out for the inspection and quality control.
