A field experiment in a randomized block design was conducted during Rabi season 2019-2020 on 13 wheat varieties with the twin objectives of objectively selecting and precisely recommending the suitable plant types to farmers of Deoria district in eastern Uttar Pradesh. The varieties were evaluated on 12 characters like plant height (cm), flag leaf area (cm2), peduncle length (cm), spike length (cm), effective tillers, grains per spike (grain number), grain weight (g), spikelets per spike, test weight (g), grain yield per plant (g), biological yield per plant (g) and harvest index (%). Normalized cumulative ranks were used to objectively select suitable crop ideotypes. The top five varieties viz., HD-2967, MACS-6222, HUW-669, K-0307 and HUW-213 were precisely recommended to farmers of this region for cultivation.

Concerned with the increase in hunger worldwide, as well as unemployment and the lack of equity in the distribution of income, the United Nations began to address genuinely Latin American scientific categories in its agendas, assemblies and task forces. The two main categories are Family Farming, with the recent establishment of the Family Farming decade (2019-2028) and the Social and Solidarity Economy as a tool for transposing the Sustainable Development Goals (SDGs) in the Territories. Together, these categories can be responsible for achieving the SDGs in 78% of the world's territory. There is a need, however, to clarify whether the science produced in Latin America also presents trends of intersection, in the search for the theoretical construction of a new paradigm of production and consumption. In this sense, the objective of this study was to identify trends in scientific production on the categories Family Farming and Social and Solidarity Economy. An adaptation of the PRISMA method was developed as a systematic literature review to identify these trends in the scientific field in Latin America.
由于关注世界范围内饥饿的增加,以及失业和收入分配不公平的问题,联合国开始在其议程、大会和工作队中真正处理拉丁美洲的科学类别。两个主要类别是家庭农业,最近设立了家庭农业十年(2019-2028),以及社会和团结经济,作为在领土实现可持续发展目标的工具。这些类别加在一起可以在世界78%的领土上实现可持续发展目标。然而,在寻找新的生产和消费范式的理论建构时,有必要澄清在拉丁美洲产生的科学是否也呈现出交叉的趋势。从这个意义上说,这项研究的目的是确定家庭农业和社会和团结经济类别的科学生产趋势。采用PRISMA方法进行了系统的文献综述,以确定拉丁美洲科学领域的这些趋势。

Remodeling impacts of domain movements in protease are of interest in many fields such as medical treatments, food processing, and bio-electronic devices.However, they are yet to be precisely explained. In this study, the remodeling effects in ficin were investigated via a deep neural network, genetic programming, and computer simulations. The replacement (Y113F) in ficin using domain movements exhibited a critical effect on the peptide compatibilities. Specifically, modification of amino acid allows the remodeling of the domain movements, and types of compatible peptides should be modulated by the remodeling. Moreover, the decision tree revealed important factors in peptides and ficin.

Detergent wastewater has to be treated to prevent water pollution, especially for the reclamation of large quantity of laundry waste water for reuse. A detergent destruction method removes detergent by using it to breakdown the activated sludge so as to prevent foaming when aerated in an SBR. Many research studies had reported methods and effects of increasing sludge reduction. A close examination of detergent destruction method to treat WHD has agreed well with the literature that activated sludge disintegration by consuming the detergent in waste water has significantly reduced the activated sludge amount by mixing with and without aeration. The high rate of sludge reduction with detergent destruction is comparable to sludge reduction with ultrasonic and other methods. This provides an economical and efficient way to breakdown sludge in improving the waste water treatment process.
洗涤废水必须经过处理,以防止水污染,特别是大量洗涤废水的回收再利用。一种洗涤剂破坏方法,通过使用它来分解活性污泥以防止在SBR中曝气时起泡来去除洗涤剂。许多研究报告了增加污泥减量的方法和效果。仔细研究了去污剂破坏法处理WHD的方法,结果与文献一致,即通过消耗废水中的去污剂来分解活性污泥,在加气和不加气的情况下显著减少了活性污泥的数量。洗涤剂破坏的污泥减量率高,可与超声波等方法的污泥减量相媲美。这为改善污水处理工艺提供了一种经济有效的污泥分解方法。

Maize (Zea mays L.) is the most abundantly produced and consumed cereal in the world. Major challenge in maize production in Africa is low soil fertility due to lack of sustainable soil fertility restoring inputs among others. This study investigated the potentials of Moringa-banana-maize mix, a biodegradable, environment friendly and abundantly available free gifts of nature in soil fertility improvement. The objective of this study was to investigate the effects of the mixture of Moringa olifera leaves (MO) +Banana Peels (BL) +Maize Stalks (MS) on yield and profitability of maize production. Specifically, to choose the right combination of the mix and determine the correct mode of application. Field and screen house experiments were conducted in 2020 planting seasons, at the Teaching and Research Farm of Kwara State University, Malete. Four treatments were considered and each represented a technology on field/screen trials. These include; A=100N+40P+30K, B= 120N+50P+40K, C= 70N+30P+ 20K and the control using the national recommended dose of 90kg/ha of NPK fertilizer (for comparison).
玉米(Zea mays L.)是世界上产量和消费量最大的谷物。非洲玉米生产面临的主要挑战是土壤肥力低,原因是缺乏可持续的土壤肥力恢复投入等。本研究探讨了辣木-香蕉-玉米这一可生物降解、环境友好、资源丰富的自然礼物在土壤肥力改良中的潜力。本试验旨在研究辣木叶(MO) +香蕉皮(BL) +玉米茎(MS)复合材料对玉米产量和盈利能力的影响。具体来说,要选择正确的混合组合,确定正确的应用方式。2020年种植季,在马勒特Kwara州立大学教学和研究农场进行了田间和纱棚试验。考虑了四种处理方法,每种处理方法都代表了现场/筛选试验中的一种技术。这些包括;A=100N+40P+30K, B= 120N+50P+40K, C= 70N+30P+ 20K,对照使用国家推荐用量90kg/ha的氮磷钾肥(对照)。

High throughput genomic data analysis is becoming an increasingly integral part of biomedical research. The information derived from gene expression analysis helps in diagnosing the treatment modality given to the patient. However, the amount of data is humongous and becomes complex to examine manually. Unsupervised machine learning algorithms perform complex tasks on an unlabelled data by clustering to comprehend the underlying structure and behaviour of the pattern. Clustering microarray data, examines the differential expressed genes found by grouping the genes based on the similarity of the expression values. In this study, we propose to elucidate the best clustering algorithm for gene expression data on various clinical conditions. The proposed study was carried on three gene expression datasets of Severe acute respiratory syndrome, Amyotrophic lateral sclerosis and Parkinson’s disease. Differentially expressed genes were found at three p-values 0.01, 0.05, 0.001 and the most significant number of genes were retrieved at p-value 0.05. We experimented the differential expressed genes on three clustering algorithms, namely Hierarchical clustering, k-means clustering and fuzzy clustering of the three diseases. The performance of the three clustering algorithms was evaluated using the internal validity index, wherein Hierarchical clustering was found to be best for gene expression data.
高通量基因组数据分析正日益成为生物医学研究中不可或缺的一部分。来自基因表达分析的信息有助于诊断给予患者的治疗方式。然而,数据量是巨大的,手工检查变得复杂。无监督机器学习算法通过聚类来理解模式的底层结构和行为,在未标记的数据上执行复杂的任务。聚类微阵列数据,通过根据表达值的相似性对基因进行分组,检查发现的差异表达基因。在这项研究中,我们提出阐明在不同临床条件下基因表达数据的最佳聚类算法。该研究是在严重急性呼吸综合征、肌萎缩侧索硬化症和帕金森病三个基因表达数据集上进行的。差异表达基因的p值分别为0.01、0.05和0.001,p值为0.05时,差异表达基因的数量最多。我们对差异表达基因进行了三种聚类算法的实验,即三种疾病的分层聚类、k-means聚类和模糊聚类。使用内部有效性指数对三种聚类算法的性能进行了评估,其中发现分层聚类最适合基因表达数据。

The Earth is isolate on its orbit motion around the Sun. The thermal radiation on Earth determines climate warmer or colder. By Kirchhoff’s law, the thermal radian on Earth must be in an equilibrium state. Which equivalents to an optimum problem. This paper establishes an equilibrium equation of thermal radiation of Earth, transmits it to an optimum problem, and proves that the equilibrium of thermal radiation of Earth is an indifferent equilibrium, neither stable, nor un-stable, based on the Stefan-Boltzmann law and the emissivity formula. The result means that the climate neither getting warmer and warmer, nor getting colder and colder.
地球在绕太阳运行的轨道上是孤立的。地球上的热辐射决定了气候变暖或变冷。根据基尔霍夫定律,地球上的热弧度必须处于平衡状态。这相当于一个最优问题。本文建立了地球热辐射平衡方程,并将其转化为最优问题,根据斯蒂芬-玻尔兹曼定律和发射率公式,证明了地球热辐射平衡是一个既不稳定也不不稳定的非稳态平衡。这意味着气候既不会变得越来越暖,也不会变得越来越冷。

It is accepted that three-dimensional physical space is a hypersurface with a Riemannian metric in four-dimensional space. The metric tensor of this three-dimensional space is defined by Einstein's equations. Another coordinate of four-dimensional space is time. In this space, the equations of the world line of a particle with a mass m are defined under certain initial conditions: the starting point of the space and the vector of the particle's initial velocity. This approach removes all the problems and contradictions noted in the monograph [1], and the resulting equations adequately describe, for example, the curvilinear motion of planets without energy change.
三维物理空间是四维空间中具有黎曼度量的超曲面。这个三维空间的度规张量是由爱因斯坦方程定义的。四维空间的另一个坐标是时间。在这个空间中,质量为m的粒子的世界线方程是在一定的初始条件下定义的:空间的起点和粒子的初始速度矢量。这种方法消除了专著[1]中提到的所有问题和矛盾,并且得到的方程充分地描述了行星在没有能量变化的情况下的曲线运动。

Introduction-There is very little literature on the floral biology, synchronization of maturity of male and female flowers, flowering phenology and controlled pollination of Dioscorea dumetorum (D. dumetorum). However, the genetic improvement of this yam species, which is widely consumed in Cameroon and has exceptional nutritional qualities, cannot be achieved without knowledge and understanding of these biological attributes or phenomena. The aim of this study was to (1) -examine the sexual reproductive biology of D. dumetorum; (2) -study the phonology of flowering in this plant species; and (3) -develop a pollination method in order to obtain hybrid seedlings.
关于薯蓣(Dioscorea dumetorum, D. dumetorum)的花生物学、雌雄花同步、开花物候和控制授粉等方面的研究文献很少。然而,如果没有对这些生物学特性或现象的知识和理解,就无法对这种在喀麦隆广泛消费并具有特殊营养品质的山药物种进行遗传改良。本研究的目的是:(1)研究dumetorum的有性生殖生物学;(2)研究该植物的开花音系;(3)开发一种授粉方法以获得杂交苗。

Over the last 40 years, the average global temperature has risen by 1°C and the catastrophic storm risk has tripled, as the latent heating power of the atmosphere grew, driven by the 15% increase in the average global concentration of the primary greenhouse gas, water vapor. Global warming and the catastrophic storm risk only worsen as the average global concentration of water vapor continues to increase at 0.4% yr.-1driving the average global temperature up at 0.2°C per decade. As the latent heating power of the atmosphere rose, the annual number of catastrophic, weather-related events increased to over 750, by 2019, 525 above the 1980 baseline of 225 annual events. Since 1980, these weather-related catastrophic events have taken tens of thousands of lives, wiped out whole communities while wreaking4.6 trillion dollars in cumulative worldwide weather-related destruction, of which 2.4 trillion dollars is the result of global warming driven increasing atmospheric latent heating power, as shown by the close correlation of major weather-related events with the average global temperature record (correlation coefficient 0.84).
在过去的40年里,由于主要温室气体——水蒸气的全球平均浓度增加了15%,大气的潜在加热功率增加,全球平均温度上升了1°C,灾难性风暴的风险增加了两倍。随着全球平均水汽浓度继续以每年0.4%的速度增长,全球平均气温以每十年0.2°C的速度上升,全球变暖和灾难性风暴的风险只会加剧。随着大气潜热功率的增加,到2019年,灾难性天气相关事件的年数量增加到750多起,比1980年225起的基线高出525起。1980年以来,这些与天气有关的灾难性事件夺去了数万人的生命,摧毁了整个社区,同时在全球范围内造成了4.6万亿美元的累计损失,其中2.4万亿美元是全球变暖导致大气潜热功率增加的结果,主要天气相关事件与全球平均温度记录的密切相关(相关系数为0.84)。
