Corn stover, which includes stalks, leaves, and husks left in the field after harvest, holds promise as a feed source for ruminant livestock due to its nutritional value. However, a lack of research on its nutritional composition has led to wasteful practices like open burning and disposal. Therefore, this study aims to determine and compare the nutritional value of corn stover between sweet and kernel corn. The samples of corn stover were collected at Universiti Sultan Zainal Abidin Farm. All samples were subjected to the cleaning, chopping, drying, and grinding processes before undergoing nutritional analysis using proximate analysis. The proximate analysis was measured based on the percentage of crude protein, ash, crude fibre, moisture, and fat. The results indicate that sweet corn stover exhibits the highest nutritional value (p< 0.05) in terms of ash, crude protein, and fat, with percentages of 5.44%, 19.04%, and 3.86%, respectively, particularly in its leaves. Additionally, the stalks of sweet corn stover contain the highest percentages of moisture (4.89%) and crude fiber (27.05%). This study found that sweet corn stover is more suitable for ruminant feed because it contains the highest levels of essential nutrients like crude protein, fat, and ash.
玉米秸秆，包括收获后留在田间的秸秆、叶子和外壳，由于其营养价值，有望成为反刍家畜的饲料来源。然而，缺乏对其营养成分的研究导致了露天焚烧和处置等浪费行为。因此，本研究旨在确定和比较甜玉米和玉米粒玉米秸秆的营养价值。玉米秸秆样本是在Universiti Sultan Zainal Abidin农场收集的。所有样品都经过清洗，切碎，干燥和研磨过程，然后使用近似分析进行营养分析。近似分析是根据粗蛋白质、灰分、粗纤维、水分和脂肪的百分比来测量的。结果表明，甜玉米秸秆的营养价值最高(p<灰分、粗蛋白质和脂肪含量分别为5.44%、19.04%和3.86%，其中以叶片含量最高。此外，甜玉米秸秆的水分和粗纤维含量最高，分别为4.89%和27.05%。这项研究发现，甜玉米秸秆更适合作为反刍动物的饲料，因为它含有最高水平的必需营养素，如粗蛋白质、脂肪和灰分。

Global warming has become an emerging and serious issue in the world, with adverse effects on human life and a threat to survival. Besides being a key contributor to a country's economic growth (EG), the manufacturing and construction sector (M&C) is also one of the major sectors that cause environmental degradation. We investigate the link between M&C’s CO2E and economic growth (both overall and sectoral growth) in the context of the Environmental Kuznets Curve (EKC) at aggregate and disaggregate levels in the Associations of Southeast Asia Nations (ASEAN), using data from 1995 to 2018. We employ the feasible generalized least squares (FGLS) and Panel-Corrected Standard Errors (PCSE) estimation techniques to examine the existence of the Environmental Kuznets Curve (EKC) at aggregate and disaggregate levels in ASEAN countries. We find evidence of an inverted U-shaped EKC at both the aggregate and disaggregate levels. After including other variables such as financial development, urbanization, foreign direct investment, and manufactured goods exports, our findings are robust and statistically significant. Our study suggests that policymakers should sanction such measures to reduce CO2 emissions from the M&C sector while maintaining economic growth.

The objective of this study is to determine the genetic diversity and structure, demographic evolution and phylogenetic relationships of Sitophilus oryzae (S. oryzae) in two types of maize: yellow maize and yellow-white maize from two localities in Senegal. Thus, individuals of S. oryzae from each locality are used, after sampling and massive rearing. The Cyt-B gene of the mitochondrial DNA (deoxyribonucleic acid) was targeted and sequenced. The obtained sequences are corrected, aligned and exploited. Overall, haplotypic diversity (Hd) is non-significantly high (0.895 ±0.058) while nucleotide diversity (Nd) is significantly low (0.016±0.003), even when populations are considered separately; the Salemata population (Hd=0.949 ±0.051, Nd= 0.015±0.003) is more diverse with P-values≤0.05. Results confirmed by polymorphism with a high number of singletons and haplotypes. This genetic variability can be explained by the fact that we had two different substrates but phenotypically very similar. The parameters of genetic differentiation, demographic and phylogenetic evolution revealed a weak genetic structuring of S. oryzae, populations in demographic expansion and poorly defined parental relationships between populations. This study provided further insight into the genetic characteristics of Sitophilus.

This research may be seen in the solar drying of several mature plants. Fruits and vegetables such as peaches and wild mint are grown in a semi-arid region near Quetta, Pakistan. Our research is confined to determining the volume of moisture removed from the distinct items and employing forced convection using three distinct mass flow rates to regulate the pace of the solar dryer, which enables us to further our study and improve the influence of mass flow rate on the quantity of water extracted from the item. A series of mathematical models for different scientists, based on the mathematical connection used, and by determining the constants for each model, which implies that each mass flow correlates to the constants of the five models, and thus the product ultimately influences them in terms of type, shape, and mass. The findings were upgraded, and analyzed the mathematical models of the scientists with our approach, which was likewise quite accurate. We infer that the mass flow rate has an effect on the coefficients of the developed model, and it is an essential component. The model may be used to forecast the moisture content of peach and wild mint during the drying system.

The COVID-19 outbreak has struck the world and has led to mortalities worldwide. On top of that, cancer diseases are the other major cause of death globally. Scientists around the globe are racing to find possible therapeutic compounds that could alleviate or manage these diseases. Searching for the potential compounds to be utilised as a treatment for SARS-CoV-2 infection and immunotherapies for cancer is in line with achieving a healthy community. The healthy community concept aims to reduce health gaps regardless of the status quo within a community. In making this concept a success, the ability to recover from health disasters such as cancer and the COVID-19 outbreak is one of the indicators. It could be achieved when humans are supplemented with proper nutrients to help manage these diseases. Studies have suggested that compounds exhibiting anti-inflammatory and antioxidant properties could help to reduce the inflammation caused by the SARS-CoV-2 infection while enhancing the immune system to address cancer diseases. The current work will review the anti-inflammatory properties of astaxanthin, tocotrienols and tocopherols, plus the beta-carotene and fucoxanthin's antioxidant properties. The potential of the studied compounds to be utilised as cancer immunotherapies will be further evaluated, as these compounds have also been reported to exhibit anti-cancer properties. The findings of this study will indicate the potential of these five compounds in managing SARS-CoV-2 infection and act as cancer immunotherapies in achieving a healthy community.

Seed dormancy is a phenomenon that prevents seeds from growing during adverse conditions. A number of factors may be responsible for this phenomenon, but one very common reason is the hardness of the seed coat as in the case of Date palm. This research was conducted to determine the effect of different priming methods on the rate of germination of date palm seeds. The treatments include cold water, hot water, H2SO4 and control in a cross randomized design. For the cold water treatment seeds were soaked for either 24, 48 or 72 hours; for the hot water treatment they were soaked for either 5, 10, or 15 minutes; and for the acid treatment they were soaked in 25 %, 50 % or 100 % of H2SO4 for 5 minutes. Twenty (20) seeds were selected for each treatment to carry out the germination experiment using moist absorbent paper. Data for germination rate was collected at 1, 2 and 3 weeks after planting (WAP). An optimal germination rate of 83% was observed at 3 WAP for the hot water treatment for 5 minutes. From this research, it can be concluded that priming generally increased the rate of germination of date palm seeds.

This research investigated the optimization of locally sourced aggregate, mixed with variable cement ratios to determine its optimum compressive strength. Samples of standard sizes of local fine and coarse aggregate were obtained at the popular excavation sites. The concrete materials were weighed, batched, mixed, cast and cured using four different mix proportions of 1:2:4, 1.2:2:4, 1.4:2:4 and 1.6:2:4 of cement, fine and coarse aggregate at constant water/cement ratio of 0.5. A total of 48 concrete cubes of 150mmx150mmx150mm were produced, cured for 7, 14, 21 and 28 days and tested. Mathematical model equation relating the compressive strength of the local stone with variability of cement was developed using Response Surface Methodology (RSM). The significance and suitability of the equation was confirmed using the analysis of variance (ANOVA). The ANOVA for the quadratic and Surface Cubic model shows that the adjusted R2 of 0.9808 and F-value of 227.76 in compressive strength of the concrete is confidently accounted for by the independent variable. This demonstrates that the equation's predictions of compressive strength for various concrete structures are accurate. Therefore, utilization of local aggregate is advised for the construction of most of the dominant low-rise residential buildings in Anambra and other neighbouring States.

This study assesses palm oil processing mills' background ionizing radiation exposure rate and is radiological health hazards in various communities within Southwestern Nigeria. At the height of 1.0 m, a digital Geiger Muller counter measured the radiation exposure rate in forty-three selected palm oil processing mills. The recorded background radiation exposure rates during non-working hours were below the recommended acceptable limit, while the background radiation exposure rates during the working hours were higher than 0.013 mR.h-1, the recommended permissible limit provided by the International Commission on Radiological Protection. During the working hours of the palm oil processing mills, the estimated absorbed dose rates and excess lifetime cancer risks were all greater than the recommended acceptable safety limits. The estimated values of the effective dose irradiated to various body organs and tissues due to radiation exposure and inhalation in the designated palm oil processing mills during their working and non-working hours were lower than the allowable global limit of 1.00 mSv.y-1. This study showed that the study area is radiologically polluted; nevertheless, the pollution may not produce any immediate radiation hazards to the residents of the area.

We propose an innovative mathematical modeling to examine the previous coronavirus disease of 2019 pandemic or (COVID-19). This analysis has been performed qualitatively through differential equation stability theory, as well as the basic reproductive value, which indicates a pandemic index, then calculated from the maximum eigenvalue of the subsequent matrix. We establish the global asymptotic stability criteria for such disease-free state. The actual COVID-19 occurrence documents and data from 01 July, 2021 to 14 August, 2022 in Pakistan are analyzed for estimation methods, leading in fitted values for biological parameters. Sensitivity analyzation is used to identify the much more relevant attributes in the developed framework. This scientific research revealed a deterministic computational formula that assesses the impact of various mitigation measures on the propagation of COVID-19 in a worldwide population. The analysis will concentrate on Pakistan, and relevant data gathered out of that region. If the method were modified for the total number of COVID-19 reported patients as well as the total number of active patients in the Pakistan region, infection rates would be approximated fairly. This research will in some way give government authorities including local hospitals additional knowledge about how to enhance precautionary efforts to minimize infection propagation.

The actual COVID-19 occurrence documents and data from 01 July, 2021 to 14 August, 2022 in Pakistan are analyzed for estimation methods, leading in fitted values for biological parameters. Sensitivity analyzation is used to identify the much more relevant attributes in the developed framework. This scientific research revealed a deterministic computational formula that assesses the impact of various mitigation measures on the propagation of COVID-19 in a worldwide population. The analysis will concentrate on Pakistan, and relevant data gathered out of that region. If the method were modified for the total number of COVID-19 reported patients as well as the total number of active patients in the Pakistan region, infection rates would be approximated fairly. This research will in some way give government authorities including local hospitals additional knowledge about how to enhance precautionary efforts to minimize infection propagation.","PeriodicalId":8540,"journal":{"name":"Asian Journal of Scientific Research","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90296258","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 delineates morphometric parameters for determining flood influence on river catchments in the Niger Delta Region using geospatial techniques. Data from the United States Geological Survey; Shuttle radar topographic mission was processed using ArcGIS 10.6 software. The results of the hydrological data analysis, compound factors, and weighted overlay approach demonstrate that early peak flows from the River Niger cause flooding along the riverbanks, as evidenced by the stream frequency findings. The Ikoli River's catchments consistently provide the River Niger with its peak discharge for a considerable time. The Orashi, Bomadi, Forcados, Nun, and Ikoli River basins all have a low relief ratio and hence little impact on floods. However, catchments with a higher relief ratio contribute more water in a shorter amount of time and produce floods in lower locations. Because of its high runoff parameters and short concentration time, the Orashi River catchment is the most flood-prone, followed by the Niger and Forcardos River catchments, which indicate "high," and the Ikoli, Nun, and Bomadi River catchments, which indicate "medium." It is therefore advised that the Orashi, Niger, and Forcados river catchments be prioritized in order to reduce the impact of floods in the Niger Delta research region.
