The field experiment was conducted at Pulse Section, ARI, Tandojam during the Rabi season 2017-18. Four different pesticides i.e. Emamectin benzoate 2.1EC, Indoxacarb 16.5EC, Flubendiamide 39.4SC and Emamectin benzoate + Lufenuron 2.7SC were applied. The results showed that after application of variable sprays, a significant reduction in pest population was observed at different intervals in field condition. The overall reduction percentage in pest population was the highest when Emamectin benzoate sprayed 2.1EC (63.92% at 24hrs, 62.03% at 48hrs, 60.00% at 72hrs and 58.90% at 1week) followed by Indox a carb. However, when Emamectin benzoate was added with Lufenuron 2.7SC, the results were not satisfactory. In, addition, Flubendiamide 39.4SC was also effective against pest but slow in action. Similarly, in laboratory bioassay, the best LT50 (17.72 hrs) and LT90 (51.25 hrs) were also observed at Proclaim at 50 ppm which further confirmed that this pesticide need short time to kill 50-90% targeted pest population. Therefore, Emamectin benzoate is highly suggested against H. armigera to reduce its population below economic threshold level.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"52 1","pages":"41-48"},"PeriodicalIF":0.0,"publicationDate":"2020-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85359778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condition of the gonad and sex of each fish was enumerated, the dissected gonads were weighed by using digital balance. It was observed from results of ova diameter measurement that all ova were found to be spherical and uniform in diameter, this indicated that the eggs were released in a single batch during the peak period of spawning (February). Values of Gonadosomatic Index was observed highest (2.97 and 5.27) in male and female respectively in the month of February. Monthly ova diameter measurement showed progressive increase from January to March (1.12 mm) peak in February. The fecundity was estimated from 10 mature fish highest was 390600 eggs 48.8 cm and 1947g at gonad weight of 510 g and lowest was 18280 from a length 33.0 cm and 486.6 g in weight and gonad weight of 53.1 g were recorded and possessing strong relationship with gonad weight. Equation of Length-weight analysis showed ideal growth very near to (3) in all cases and coefficient of condition (Kn) indicated that all samples of both sexes Cyprinus carpio found with satisfactory growth from Indus River, Jamshoro, Sindh, Pakistan. It was concluded that Cyprinus carpio breeds once in year with peak in February. As indicated form both GSI and ova diameters.

This delta plays animportant role in enhancing the economic, environmental and ecological welfare of the people in this region. This delta constitutes seventeen main creeks. It forms a remarkably uniform landform with large extensive mud flats being intervened by narrow creeks, which are remains of old Indus tributaries.The ecosystem of Indus Delta is characterized by having rich nutrients which offer a nursery as well as an early feeding ground for many varieties of shrimps and fish as well. This study provides the baseline information about temperature, salinity, and bathymetry in different creeks of the Indus delta. Out of 17 creeks, 13 creeks were studied during the survey period. In the study area, the temperature ranged from 14.5 oC- 31.1 oC in a year. The temperature difference is nearly constant in mid-May toward mid-September (29.60 oC -31.10 oC), except in the Chani Creek area, where it remained as 28 oC- 29.4 oC.During mid-September to November (Post Monsoon), the temperature was slightly lower than monsoon (23.2 oC to 29.4 oC). There is little effect of seasonal shift at the western creeks, Issaro, Waddi Khuddi, Patiani, Mal, Dabbo, Richhal, Chann, Chani, and Hajamro as compared to eastern Creeks and Jhang River. During Monsoon, the highest salinity values (32.9 to 36.9 psu) have been recorded at Issaro and Waddi Khuddi Creeks.

In this paper, we use the transfer learning aspect to fine-tune the existing pre-trained networks which provide us an edge for the improved classification accuracy. We then apply various decision-level fusion strategies to combine the class probabilities from the individual pre-trained networks for further boost in recognition performance.

We undertook a comprehensive cross sectional study to assess the prevalence of obesity among middle school children.

Out of 300 female students, 150 students belongs to public and remaining150 to private schools. Likewise out of 300 male students, 150 students belong to public and 150 belong to private schools. Body Mass Index (BMI) was used to determine prevalence of overweight and obesity. BMI for age was computed by measuring height and weight of each student. The result shows that the mean age of female students was 12.40 years and means height was 57.94 inches. While their male counterparts had a mean age of 13.19 years and mean height was 60.50 inches. The prevalence of obesity among female students was 9.3% and 17.34% in public and private schools respectively and combined obesity was 13.3% similarly the prevalence of obesity among male students was 18.7%, 17.3% and 18.0% in public, private schools and combined total respectively. The high prevalence of obesity among schoolchildren seems to be due to the sedentary life style, lack of recommended physical activity on daily basis as well as consumption large amount of calories in the form of junk food or fast food. High-tech devices like mobile, cordless phones and remote controls also contribute to couch culture and prevent children of necessary walk. Furthermore, it was also observed that people are less aware of health, and psychological issues of child obesity.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"22 1","pages":"103-108"},"PeriodicalIF":0.0,"publicationDate":"2020-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76550359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The heavy minerals are seen upto 2% and are mostly ilmenite. Moreover, the shape of grains indicate that the source was not far away and both the primary porosity and permeability have been decreased due to the secondary solutions, that are mostly carbonate in the form of calcite. The whole rock geochemical analysis revealed that at some stratigraphic positions some shales are highly rich in aluminum contents and thus qualify for bauxite deposit but need further evaluation for commercial use.
