The residual toxicity test revealed that emamectin benzoate is highly persistent with a residual toxicity of 28 days compared to 1 mg/L abamectin in which its residual toxicity wears off after 24 hours of treatment. However, the 100 mg/L emamectin benzoate was highly toxic for the adults of Amblyseius longispinosus, whereas 1 mg/L abamectin showed no toxicity under laboratory conditions.","PeriodicalId":124576,"journal":{"name":"Science and Humanities Journal","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116999334","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}

Sweet basil is a nutritional food which supplies vitamins, particularly A, B and minerals such as Fe, Mn, and 6, Mg. This study was conducted to investigate the effects of Zn, Fe, Cu, and Mn biofortification on the growth, yield, and chlorophyll contents of sweet basil (Ocimum basilicum L.) under pot experiment. All of the pots, except T (control), 0 were applied with the recommended rate of NPK for sweet basil (60-60-60 kg ha ), together with the varying levels of micronutrients such as Zn, Fe, Cu, and Mn -1-1 (applied at 4, 8, and 12 kg ha ). The results of the study revealed that the application -1 of Zn at 4kg ha enhanced the plant height, root length, fresh and dry root weight of sweet basil. The higher number of primary branches and chlorophyll contents were -1 obtained from treatments applied with 12 kg ha Mn. The addition of Fe with 4 to 12 -1 kg ha increased the fresh weight of leaves and herbage yield. Cu biofortification at -1 4kg ha enhanced the herbage weight and yield of sweet basil. These results show the beneficial effects of micronutrient biofortification on the growth and yield parameters of sweet basil as well as its chlorophyll contents. Meanwhile, the amounts of Zn, Fe, Cu, and Mn in the soil were likewise enhanced with the addition of these nutrients. In return, the availability of these micronutrients for plant uptake was also enhanced.","PeriodicalId":124576,"journal":{"name":"Science and Humanities Journal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131625675","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}

This study looks at the characteristics of the two taro soils as affected by the application of four organic amendments used as treatments (Biochar, Mucuna, Erythrina, and grass). The effects of nutrients released from these four treatments were analyzed in the soil laboratory using various soil tests such as Labile Carbon, Fluorescein diacetate (FDA) hydrolysis activity, Potentially mineralizable nitrogen (PMN), Mineral nitrogen, Urease assay, and Phosphatase assay. The results showed that Erythrina and Mucuna are the two cover crops that significantly responded to the two soils. In terms of carbon mineralization, Mucuna and Erythrina fallow mulches had higher means compared to grass and biochar. The difference in the carbon mineralization could be attributed to the characteristics of Mucuna and Erythrina are both legume mulches which have lower C: N ratio. Therefore, they have faster rates of mineralization compared to grass and biochar fallows. However, at the highest rate of application (45 tons/ha), Mucuna was found to have faster rate of mineralization compared to Erythrina. From the other tests that were being carried out, Grass and Erythrina cover crops showed the highest levels of mean biological activity at their highest rate of application (45 tons/ha) on both soils. Mucuna and biochar covers, on the other hand, showed highest levels of mean biological activity at the lowest rate of application (15 tons/ha).","PeriodicalId":124576,"journal":{"name":"Science and Humanities Journal","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121193316","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}

These negative impacts include game addiction, online risks, and exposure to child-inappropriate content. Studies also show that parents play a significant role in mitigating these negative impacts by applying strategies such as monitoring and supervision of children in their use of video games. This case study aimed to determine specific strategies adopted by parents to mediate their children's video game playing and find out what their outcomes are. In-depth interviews with parents of children aged 7–14 revealed that they generally had negative perceptions of video games. These negative perceptions resulted to either restrictive or active mediation or a combination of both. Parents' time with their children and the place where their children played have been found as significant predictors of mediation. Moreover, the strategies informants used to manage their children's video game playing resulted in more positive than negative outcomes. Those who engaged in active mediation and co-playing established good parentchild relationship and led to children's obedience to rules. Restrictive mediation either had positive or negative outcomes. The most common negative outcomes were parent-child conflict and children's disobedience to the rules their parents laid out to limit their video game playing.","PeriodicalId":124576,"journal":{"name":"Science and Humanities Journal","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122431369","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}

These variables include the thickness of banana slice, oil levels, sodium metabisulfite levels, salt levels, blanching time, and frying temperature. The variables that were found significant are frying temperature, salt, and oil levels. These were used to identify the most suitable formulation for the development of air-fried banana chips using Central Composite Design (CCD) of Response Surface Methodology (RSM). The sensory quality evaluation of the product revealed that frying time significantly influenced the color, aroma, taste, crispiness, oiliness, and general acceptability of air-fried banana chips. The results also showed that salt significantly affected the aroma, taste, crispiness and general acceptability, while the addition of oil influenced the aroma, taste, crispiness, and oiliness of the product.
