Study of delay factors in civil projects (Case Study: FHWA-04)

Paper ID- AMA-07-08-2021-10551

The execution of most development projects nationwide is national and its validity is concentrated in the Ministry of Housing. However, according to the reports, nearly a large number of those projects have failed to be completed in the anticipated time. Any size of the budget and allocations approved for development projects, which contribute significantly government investments and expenditures. If it is unrealistic or less expert, the likelihood of the execution period will be longer. One of the most common development projects, which is not often defined in accordance with the pre-defined schedule and is accompanied by significant time delay, is the bridge structure. Therefore, in this study, based on structural special importance, the factors of delay in the bridge structure were studied. The bridge studied in this study is a highway bridge No. 4 of the United States (FHW04). In this study, according to experts and through questionnaire, the most important factors that delay the implementation of the proposed bridge are investigated. the results of the study show that among the three main indices of delay (financial factors, supervision and executive management) in the project implementation process, the indicator of financial factors with a normal weight of 0.419. Executive management index with normal weight of 0.293, and the normal weight monitoring indicator is 0.248 for the third priority.

We reporting here on determining the effect of extracts of such medicinal plants as Maral root and stinging nettle, when feeding recipient cows in a dry period, on the prevention of postpartum complications in animals and a reduction in the recovery period of the reproductive system. It was found that on the 30th day in animals that received additional medicinal extracts in the diet, an increase in the content of neutrophils and platelets in the blood and protein fractions of blood serum was observed, which indicates an increase in the resistance of the animal's body. An increase in the bactericidal, lysozyme activity of the blood serum of recipient cows and the phagocytic activity of leukocytes also indicates an increase in the immune response of the animal's body in response to the penetration of foreign microflora into the body. According to the results of the studies, it was recommended to add a two-component phytobiotic feed additive to the main diet based on extracts of medicinal plants Maral root and stinging nettle at a dose of 50 g per head per day in the ratio of components: 100 kg of compound feed, 0.5 kg of maral root extract, 2, 5 kg of stinging nettle extract.

Comparative Performance of Different Paddy Threshing Methods in Odisha, India

Paper ID- AMA-07-08-2021-10549

Four paddy threshers; namely power operated thresher-cum-winnower, power-tiller operated thresher, tractor operated thresher and tractor operated half feed thresher were evaluated with three varieties of paddy at three levels of grain moisture content. Their performances were compared with conventional methods i.e. hand beating and bullock treading. Threshers were evaluated with respect to output capacity, threshing efficiency, cleaning efficiency and grain losses. It was found that with increase in grain moisture content, the output capacity, the percentage of un-threshed grain and total grain losses increased while the percentage of grain breakage decreased for all the threshing methods used. Maximum output capacity was observed in case of tractor operated paddy thresher while it was minimum in case of conventional hand beating.

Analysis of genetic estimates and divergence of some Indian and exotic genotypes of Sesame (Sesamum indicum L.)

Paper ID- AMA-05-08-2021-10547

Sesame (Sesamum indicum L.) is one of the important oilseed crop which is widely cultivated in tropical and subtropical areas of Asia, Africa and South America since ancient times. Present study was carried out to evaluate the phenotypic variability in sesame genotypes from different parts of West Bengal and some major sesame growing states of India along with eight genotypes from USA, Bulgaria and Bangladesh, using 12 quantitative traits. Genotypes like CUMS 17, CUHY 57, MT 75, Atghara, RT 351 were to some extend better performed than the check variety TKG 22 and GT 10 regarding yield and other yield attributing traits in both locations (Ranaghat and Baruipur) At both genotypic and phenotypic level, seed yield per plant showed significant positive correlations with 1000 seed weight, seeds per capsule and capsules per plant and significant negative correlation with days to maturity, which suggests that seed production is mostly depends on these mentioned characters whereas early maturity depends on early flowering. Highest oil content was observed in TKG-352(53.13) followed by EC 96, CUMS 17, RT 351, Shekhar, GT 10 those recorded > 48% oil contents. Three genotypes namely AT 306, RT 351 and HT 2 recorded higher value of soluble protein content of > 17 %. In cluster analysis genotypes grouped into various clusters exposed that there was no relationship between geographical distribution and genetic diversity. These results have an important suggestion for sesame genotypes agro-morphological characterization, evaluation and improvement in future.

Performance evaluation of fuel blends using canola oil- based biodiesel and diesel fuel in a farm tractor

Paper ID- AMA-05-08-2021-10546

The purpose of this study was to determine the effects of use of petroleum diesel (D100) and biodiesel (B100) fuel blends compared to pure diesel on the engine performances of a farm tractor with a tillage implement in field. The experiments were conducted on a tractor engine using a blend of biodiesel and petroleum diesel in the ratio of 20, 50, 80 and 100 % of biodiesel in the blends. The tractor performed with each blend doing standard tillage in field spots of 2500 m2 with three repetitions. The specific fuel consumption improved as percentage of biodiesel increased in the blend, obtaining a minimum of 0.0966 (L/kWh) for Biodiesel Alone B (100). While the energy efficiency in the usage of fuel by the tractor decreased as the percentage of biodiesel in the blend was increased, showing a maximum value of 104.9 % for a 20 % of Biodiesel in the blend, with respect to the Diesel fuel (D100), whose efficiency was considered being 100 % as a referential value.
