This study evaluates the effectiveness of localized application of super granular urea on lowland rice production compared to the farmer practice (FP). To this end, a two-factor Split Plot design was implemented: the practice factor with two modalities, Farmers' Practice (FP) and Deep Urea Placement (DUP), and the variety factor with two modalities, Sahel 108 and Tox 728-1. It was found that the most important height and plants collar diameter were obtained with the practice of deep placement of urea with respectively 68.10 cm and 4.02 cm. A significant effect of variety on growth parameters was also found. Indeed, the variety Tox 728-1 had the greatest height (63.63 cm) and the variety Sahel 108, the largest diameter at the collar (3.81 cm). Overall, the best performance in terms of growth is recorded with the practice of deep placement of urea regardless of variety. Heading was earlier with the variety Sahel 108 under deep urea placement. As for tillering and the number of panicles produced, they are statistically more important with the variety Sahel 108 under deep urea placement with 45±6.61 tillers/m² and 192±10.69 panicles/m² respectively. Considering the grain yield, it is more important with the DUP whatever the variety. It is 3055±148.39 kg/ha for the variety Sahel 108 and 2877.5±339.12 kg/ha for the variety Tox 728 -1 with this practice. These results indicate that, overall, DUP has a positive effect on the agromorphological parameters of rice in Lower Casamance.

An efficient In vitro plant regeneration was established in Capsicum annuum L. from cotyledon explants. The best performance i.e., 80% of the explants responded for multiple shoot bud proliferation on MS medium containing 10 mg/l Zeatin. The maximum number of buds per explants was 50.28 ± 2.69 and the bud length of 0.5 ± 0.22 cm was obtained in this medium after 30 days. The average number of 80.32 ± 0.16 multiple shoot bud and the average shoot bud length of 1.0 ± 0.19 cm was attained on the same medium after 90 days. These shoot buds on transfer to MS + 10 mg/l Zeatin + 2.0 mg/l GA3 yielded 6.3 ± 0.35 number of multiple shoots with an average shoot length of 4.6 ± 0.62 cm after 30 days. Shoots rooted well (80% of induced shoots) on half strength MS medium supplemented with 0.5 mg/l IBA. The average number of roots per shoot was 8.2 ± 0.79 and the average root length of 4.5 ± 0.58 cm was recorded. About 80% of In vitro derived plantlets were survived under open field conditions.

Cancer therapies bring hope to the suffering and dying patient. However, cancer research is complex and expensive. In addition, cancer is not just one disease but many. Each with its characteristics, risk factors, causes, and treatments—currently, 35 U.S. Code § 103 (obviousness) rejections are a rate-limiting step for acquiring a patent. Unfortunately, rejecting novel cancer-related patent applications based on obviousness inhibits funding for much-needed drug development and research.

Background: Acute subdural hematoma is one of the frequent complications of severe head trauma, it is a neurosurgical emergency. The aim of this study is to determine and evaluate the outcome of patients operated by craniotomy versus decompressive craniectomy. Methods: This is a retrospective and analytical study over two years from January 01, 2019 to December 31, 2020. Results: 73 patients were included in the study including 63 men and 10 women with a sex ratio of 6.3. The average age was 37.84 years old. The traffic accident was the most common in 47.95% of cases. Of the 73 patients, 54 under went decompressive craniectomy and 19 had craniotomy. The predominant initial Glasgow score in the decompressive craniectomy was less than 8 and in the craniotomy between 13-15. The mean hematoma thickness was 9.54 mm for the decompressive craniectomy and 11.07 mm for the craniotomy. The mean deviation from the midline of the decompressive craniectomy was 7.25 mm and 7.21 mm for the craniotomy. The mortality rate found in décompressive craniectomy was 46.30% and 52.63% for craniotomy. Conclusions: There is no consensus in the literature on the surgical technique, so the management of acute subdural hematoma depends on the expertise of the neurosurgeon on a case-by-case. In order to determine a surgical strategy, a prospective study is necessary.

Chronic arsenic toxicity (arsenicosis) as a result of drinking arsenic-contaminated groundwater is a major environmental health hazard throughout the world, including India. During the last four decades arsenic contamination of groundwater in nine districts out of twenty in West Bengal has become a serious problem. About 20% population of West Bengal in nine districts (Malda, Murshidabad, Nadia, North 24- Parganas, and South 24-Parganas, Kolkata, Howrah, Hooghly and Burdwan) are affected by arsenic problem. To prevent this harmful effect, every people need to have proper knowledge and positive attitude towards arsenic. In this study, the researcher constructed a standardized tool of knowledge and attitude towards arsenic to assess the knowledge and attitude level of arsenic among the people of arsenic contaminated area. The researcher took item analysis method to assess the quality of the items of every section. Then the tools were measured the reliability by the Pearson’s product moment correlation method. Primarily two self-administered tools of 39 knowledge items and 32 attitude items regarding arsenic was applied among the people of Nadia district of West Bengal. Therefore, the researcher analyzed the collecting data and eliminated the poor items on the basis of difficulty value and discrimination index. After elimination of distracting items, 25 items in knowledge section and 25 items in the attitude section were retained as a final form of tool regarding arsenic. Thereafter the final form of tools applied among 60 general people to calculate the reliability of the tools by test-retest reliability method. The researcher found significant reliability in knowledge and attitude tools. These standard tools can assess the knowledge and attitude level regarding arsenic among the people of arsenic contamination area with accuracy.
饮用受砷污染的地下水造成的慢性砷中毒(砷中毒)是全世界包括印度在内的一个主要环境健康危害。在过去的40年里，西孟加拉邦20个地区中有9个地区的地下水砷污染已经成为一个严重的问题。西孟加拉邦9个地区(Malda, Murshidabad, Nadia, North 24-Parganas, South 24-Parganas，加尔各答，Howrah, Hooghly和Burdwan)约20%的人口受到砷问题的影响。为了防止这种有害影响，每个人都需要对砷有正确的认识和积极的态度。本研究构建了标准化的砷知识态度测评工具，对砷污染地区人群的砷知识态度水平进行测评。研究人员采用项目分析法对每个部分的项目质量进行评估。然后用Pearson积矩相关法对工具的可靠性进行了检验。主要是在西孟加拉邦纳迪亚地区的人们中应用了39个关于砷的知识项目和32个态度项目的两个自我管理工具。因此，研究人员对收集的数据进行分析，并根据难度值和辨别指数剔除不良项目。在剔除干扰项后，知识部分和态度部分分别保留25项和25项作为砷的最终工具形式。然后将最终形式的工具应用于60名一般人群中，采用重测信度法计算工具的信度。研究人员发现，知识和态度工具具有显著的可靠性。这些标准工具可以准确地评估砷污染地区居民对砷的知识和态度水平。

Potentiality of ascorbic acid on retardation of senescence was analysed using leaves of aquatic plant species namely Eichhornia crassipes and Jussiaea repens. Changes of some biochemical parameters like chlorophyll, protein as well as activity of catalase enzyme were analysed as reliable senescence indices during leaf senescence of the species under ambient ageing condition. With the progress of ageing duration from zero (0) to 96 hours the levels of chlorophyll and proteins in leaf discs gradually declined in both control and ascorbic acid treated samples. However, in the ascorbic acid treated samples the rate of decline was found to be much slower. The activity of the enzyme catalase was found to decrease progressively during the observation periods (0, 24, 48 and 96 hours) regardless of the treatment. Ascorbic acid partially alleviated the rapid fall of the enzyme activity during the ageing periods. Thus, ascorbic acid seems to be a potent senescence deferral agent for the experimental aquatic plant species

Bread is a product obtained by cooking, under technologically appropriate conditions, a dough, fermented or not, prepared with wheat flour and other ingredients. Carrot (Daucus carota) is a plant of the Umbelliferae family, characterized as one of the most important olive crops, due to its great consumption worldwide. The present work aimed to produce and evaluate the sensory acceptance of bread made from carrots. Sensory analysis was performed using affective methods. For this purpose, 4 formulations were prepared and consisted of (A) 30% raw carrots and 70% wheat flour, (B) 30% carrot puree and 70% wheat flour, (C) 40% raw carrots and 60% wheat flour and (D) 40% carrot puree and 60% wheat flour. The acceptability index was evaluated in terms of appearance, color, texture, odor, flavor, aftertaste and aroma on a 9-point hedonic scale at the extremes “very much disliked and extremely liked”, for 50 untrained tasters. The results showed that formulation C with 40% raw carrot puree and 40% wheat flour, 10% yeast, 3% salt and 7% water, showed greater acceptability. In view of this, it is concluded that formulations B and C were accepted and are recommended to be used as a partial replacement of wheat flour.

This study was conducted to ascertain the allelopathic relationship between Tithonia diversifolia and some cucurbits C. sativus, C. colocynthis and C. lanatus. Seeds of the cucurbits were treated every 24 hours with 10ml of different concentrations (0% [control], 25%, 50% and 100%) prepared from 2.5g/ml stock solution of aqueous extracts of T. diversifolia. Two experiments (the Petri and micro plot experiments) were conducted concurrently and were both laid out in a completely randomized design with four replicates in the Green house of Centre for Ecological Studies, University of Port Harcout. Data were taken on Radicle length, Plumule length, Number of leaves (NOL), Plant Height (PH), Fresh weight and Dry weight for five weeks after plating / sowing for the test cucurbits. Results showed that, compared to the control, there were no significant (p≤0.05) difference in all the parameters investigated for the three cucurbits studied after treatment with different concentrations of T. diversifolia. Results from the analysis shows that for laboratory (Petri dish) experiment, T. diversifolia inhibited the plumule of C. calocynthis in 25% concentration at 5 days after plating; the radicle and plumule of C. lanatus in 50 and 100% concentrations at 5 and 7 days after plating (WAP). T. diversifolia showed no effect on the radicle and plumule length of C. sativus. For Green house (potted) experiment, it stimulated the growth of C. sativus and C. calocynthis in 50% at 5WAP and stimulated the growth of C. lanatus in 25% at 5WAP. Conclusively, there are possibiliites that T. diversifolia possess allelopathic effect on the growth and development of some cucubits.
摘要本文研究了异叶铁藤与几种葫芦属植物C. sativus、C. colocynthis和C. lanatus的化感关系。用2.5g/ml百叶松水提物原液配制10ml不同浓度(0%[对照]、25%、50%和100%)处理葫芦种子，每24 h处理一次。在哈考特港大学生态研究中心的温室中，同时进行了两项实验(培养皿试验和微型小区试验)，均采用完全随机设计，共4个重复。试验葫芦在镀后/播种后5周，采集根长、胚芽长、叶片数(NOL)、株高(PH)、鲜重和干重的数据。结果表明，与对照相比，不同浓度的金合欢处理后3种葫芦的各项指标均无显著差异(p≤0.05)。分析结果表明，在实验室(培养皿)实验中，在镀后5天，以25%的浓度，百里叶对钙胞丝酵母的胚珠有抑制作用;镀后5和7 d (WAP)， 50%和100%浓度的大叶蝉根和小叶蝉子叶。不同叶分对红花的胚根和胚珠长度没有影响。在温室(盆栽)试验中，在5WAP下，对sativus和calocynthis的生长促进率为50%，对C. lanatus的生长促进率为25%。综上所述，可能对某些葫芦的生长发育具有化感作用。

Two experiments (the Petri and micro plot experiments) were conducted concurrently and were both laid out in a completely randomized design with four replicates in the Green house of Centre for Ecological Studies, University of Port Harcout. Data were taken on Radicle length, Plumule length, Number of leaves (NOL), Plant Height (PH), Fresh weight and Dry weight for five weeks after plating / sowing for the test cucurbits. Results showed that, compared to the control, there were no significant (p≤0.05) difference in all the parameters investigated for the three cucurbits studied after treatment with different concentrations of T. diversifolia. Results from the analysis shows that for laboratory (Petri dish) experiment, T. diversifolia inhibited the plumule of C. calocynthis in 25% concentration at 5 days after plating; the radicle and plumule of C. lanatus in 50 and 100% concentrations at 5 and 7 days after plating (WAP). T. diversifolia showed no effect on the radicle and plumule length of C. sativus. For Green house (potted) experiment, it stimulated the growth of C. sativus and C. calocynthis in 50% at 5WAP and stimulated the growth of C. lanatus in 25% at 5WAP. Conclusively, there are possibiliites that T. diversifolia possess allelopathic effect on the growth and development of some cucubits.","PeriodicalId":394579,"journal":{"name":"International Journal of Scientific Research Updates","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125612869","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 study was conducted to evaluate the growth performance, carcass yield, and meat retail cut properties of stressed broiler chickens supplemented with different levels of rice-washed probiotics. Two hundred-day-old broiler chicks were randomly distributed into four (4) treatments following the Complete Randomized Design. Treatments were: T1- Control (w/o probiotics); T2- 15 ml/lit probiotics: T3 – 20 ml/lit probiotics: T4 – 25 ml/lit probiotics. Chicken exposure to light was limited to only 16 hours per day to facilitate stress, which is turned off every 4:00 pm up to 12 midnight throughout the experimental period of 42 days. Based on Analysis of Variance (ANOVA) results revealed that growth parameters including slaughter weight, carcass weight, and thigh weight were significantly (p≤0.05) affected by the supplementation of rice-washed probiotics. Thus, the study concluded that rice-washed probiotic supplementation at a level of 20 ml/lit and 25 ml/lit can be effectively utilized in enhancing the performance and carcass yield of broiler chickens under light stressed conditions.

The present ethnobotanical study is being carried out in the town of Mbanga on the use of plants in the traditional pharmacopoeia. Its major concern is to document medicinal plants and therapeutic recipes which will serve as a database for the population. To do this, an ethnobotanical survey was conducted in September and October 2011 and completed in August 2020. It collected a certain amount of information relating to the use of medicinal plants as an alternative to primary health care. This study, conducted with two hundred and fifty-five (255) respondents, identified eighty (80) cases of health problems, some of which are only symptoms of illnesses. Three hundred and thirty-nine (339) therapeutic recipes involving one hundred and eighteen (118) medicinal plants belonging to fifty-five (55) botanical families have been indicated as entering into their treatment. The therapeutic recipes are made up of either a single plant or a combination of several plants. Only species that have been mentioned at least twice have been taken into account. Cymbopogon citratrus has the highest used specialization index, 0.35; it is the species mostly used in therapeutic recipes. Acute illnesses are the most common groups. The plants are well used by the people of Mbanga in the treatment of various diseases because the exploitation index is 4.23. The plant species used in the treatment of diseases in Mbanga are mostly reported in other parts of Cameroon and the world in the treatment of the same diseases.
