Over the past decades, dominant Western institutions have increasingly perceived China as a challenge to a US-centric world order and framed it as a threat to Western values. We propose that understanding the synergies between these institutions’ messaging on China and the reported growing number of incidents of anti-Asian racism can illuminate what drives the latter, especially in the COVID-19 era. We draw from theories of globalization, political socialization, and stigma to identify dominant narratives on China during COVID-19 through a critical discourse analysis of public documents, spanning close to three years, from governments, civil society entities and actors influential in public policy, and Western mainstream media. We show that the dominant Western narrative is that China is a threat to Western values and to humanity, both perceived as interchangeable. This narrative is constructed through double standards and the omission of relevant geopolitical contexts that might help Western publics to develop a more nuanced perspective of China’s role in world affairs. The ideological work of “othering” China and whoever refuses to condemn it is all but inevitable, as is the message of “Us versus Them” with the potential to legitimize anti-Asian racist beliefs, attitudes, and behaviours. Discourse is not a slender surface of contact, or confrontation, between a reality and a language (langue) […] in analysing discourses, one sees the loosening of the embrace [between] words and things, and the emergence of a group of rules proper to discursive practice. These rules define not the dumb existence of a reality […] but the ordering of objects [performing] a work that […] displaces its own data, and reveals, at the end of the day, a quite different task. A task that consists of not - of no longer - treating discourses as groups of [signifiers] but as practices that systematically form the objects of which they speak. Of course, discourses are composed of signs; but what they do is more than use these signs to designate things. It is this more that renders them irreducible to the language (langue). It is this 'more' that we must reveal and describe. Michel Foucault, The Archeology of Knowledge, 1972, P. 48 & 49

Monkeypox virus infection and death toll are alarmingly increasing the world over. An effective treatment and control protocol is essential to fight this viral infection. In this, in silico research article, we analyzed three hypothetical protein sequences from the Monkeypox virus. We studied various parameters of these proteins including amino acid composition, instability index, isoelectric point, extinction coefficient, aliphatic index, GRAVY, etc. We also performed MSA to get a clear idea of the mutation and its type and the virus's role over time. We find out various domains and their function that permit the virus during its infection processes. The amphipathicity is validated well. This study will help scientists to develop effective drugs against this virus.

Let p be an odd prime number. This work applies some group concepts to construct the Wreath Product of two permutation groups of prime degrees. We used numerical approach to investigate and determine the primitive and regular nature of the constructed Wreath Product Group of degree 5p. We apply Computational Group Theory (GAP) to facilitate as well as validate our results.

Agriculture plays a vital role in providing food globally including Guyana, however, the increase in the human population adversely decreases farm size, which results in nutrient depletion on existing farms due to extensive farming activities on the same land season after season. Biochar is commonly used as a non-conventional farming system to enhance the soil’s quality and simultaneously to produce better yield of various staple food crops. Therefore, the purpose of this study was to evaluate the effectiveness of coconut biochar as a soil amendment and to quantify its impact on the growth performance of sweet peppers (Capsicum annuum L.) in Joanna, Black Bush Polder, Corentyne, Berbice, Guyana. A field trial was carried out using the randomized block experimental design with 15 g, 30 g, 45 g biochar; 2 g NPK; and control, each replicated on clayey loam soil. The physico-chemical characteristics of biochar were determined along with the soil-biochar mixture before and after cultivation. In addition, vegetative and reproductive parameters of the sweet peppers, nutrient content of the fruits and chlorophyll content of the leaves were examined. The results obtained from this study revealed that biochar played a minor role in enhancing the yield of the sweet peppers (31.44 g) and amending the soil characteristics when compared to the control. It was observed in this study that soil pH (8.4), organic carbon (1.9 %), carbohydrates concentration (1.25 %) of fruits and chlorophyll content (a:5.6097µM, b: 5.4833 µM, total: 11.093 µM) of the leaves increased with the application of biochar. Based on the obtained results, it can be inferred that biochar may potentially be recommended in the range of 30 g to 45 g as a soil amendment to enhance the growth performance of sweet peppers, however, further experiments with diverse crops and soils are still required to investigate the use of the exact quantity of biochar sourced from different materials.
农业在提供包括圭亚那在内的全球粮食方面发挥着至关重要的作用，然而，人口的增加对农场规模产生了不利影响，这导致了现有农场的养分枯竭，因为在同一块土地上进行了广泛的农业活动。生物炭是一种常用的非常规耕作系统，可以提高土壤质量，同时提高各种主粮作物的产量。因此，本研究的目的是评估椰子生物炭作为土壤改良剂的有效性，并量化其对圭亚那Joanna、Black Bush Polder、Corentyne、Berbice等地甜椒(Capsicum annuum L.)生长性能的影响。田间试验采用随机区组试验设计，分别添加15 g、30 g、45 g生物炭;2 g NPK;对照，每一个都在粘壤土上复制。测定了生物炭的理化特性，并对培养前后的土壤-生物炭混合物进行了测定。此外，还测定了甜椒的营养和生殖参数、果实的营养含量和叶片的叶绿素含量。研究结果表明，与对照相比，生物炭对甜椒产量的提高(31.44 g)和土壤特性的改善作用较小。结果表明，随着生物炭的施用，土壤pH值(8.4)、果实有机碳含量(1.9%)、碳水化合物浓度(1.25%)和叶片叶绿素含量(a:5.6097µM, b: 5.4833µM，总含量:11.093µM)均有所增加。根据所获得的结果，可以推断，生物炭可能推荐在30 g至45 g范围内作为土壤改良剂，以提高甜椒的生长性能，然而，仍然需要对不同作物和土壤进行进一步的实验，以研究来自不同材料的生物炭的确切数量。

Background: Comprehensive routine screening and adequate selection of the prospective whole blood donor protects his health and safety as well as that of the recipient. Objectives: The main objective of this study was to determine the complete blood and absolute CD4+ T lymphocyte cell counts of apparently healthy prospective whole blood donors. Participants and Methods: This was a hospital based prospective study. A form was designed by the researchers for data collection. The socio demographic status, complete blood cells and absolute CD4+vel counts of apparently healthy whole blood donors who had tested seronegative for HIV, hepatitis B and C markers was captured . Obtained data was analysed with the statistical package for the social scientist software version 20 Results: One hundred male (97.1%) and three female (2.9%) apparently healthy prospective whole blood donors were studied. The median age of study subjects was 30 years. Obtained median blood cell values were 13g/dl, 40%, 4.9/nl and 203.9/nl for haemoglobin concentration, haematocrit, total white cell and platelet counts respectively. The median values for the mean corpuscular haemoglobin concentration (MCHC), mean corpuscular haemoglobin (MCH) and mean corpuscular volume (MCV) of studied blood donors were 32.6g/dl,27.7pg and 85.7fl respectively. Observed prevalence of subnormal blood cell counts for haemoglobin concentration, total white cells and platelets were 12.6%, 25.2%, 13.6% respectively. Also subnormal values for MCHC, MCH, and MCV were 11.7%, 26.2%, 16.5% respectively among studied whole blood donors. No higher than normal blood cell count values were observed. Median values for erythrocyte sedimentation rate and CD4+ T lymphocytes were 8.4mm/hr and 876.2cells/µl respectively. The percentage of subnormal CD4+T lymphocyte count was18.4% Conclusion: A significant percentage of apparently healthy prospective whole blood donors had subnormal blood cell and CD+ve T lymphocyte values. Obtained normal values were comparable with local reference range reports from previous studies in Nigeria and other parts of Africa.

Global warming is caused by the lack of N and P and decrease of CO2 assimilation and decrease of CO2 fix and decrease of heat absorption. Lack of N and P is caused by the elimination of NOx and NP in waste water. Global warming will stop if developed countries stop the elimination of NOx and NP. CO2 assimilation will be activated and Global warming will stop. But developed countries hated NOx and are eliminating NOx by the reaction with ammonia and set up a rule that if NOx is detected in exit gas, we will order the stop of factory The author presented petition to stop the rules which ask the elimination of NOx NP. The author is asking top persons of the countries to present a note that you need not add ammonia. And if NOx ix detected in exit gas we do not ask the stop of your factory. Global warming will stop if developed countries stop the elimination of NOx and NP. CO2 assimilation is activated and Global warming will stop.

Sapera goats have many excellencies but their population is still low. Efforts that can be made are to provide female goats that have the potential to give twin birth type and have high productivity. This is obtained through an assessment of body performance. The mother and her offspring of Sapera goats with twin and single birth types have different body performance. These differences can be a reference to describe the productivity of Sapera Goats on these farms. This research was conducted in January 2023 at Kuncen Farm, Mijen District, Semarang City with the criteria for a mother Sapera goat aged between 1.5 - 2 years and her offspring aged between 3 - 5 months. Based on the results of the study, the body performance of Body Length (BL), Body Height (BH), and Chest Circumferences (ChC) were superior to the mothers and offspring of the twin birth type, while Canon Circumferences (CC) and Head Length (HL) performance of the mother and her offspring in each type of birth do not have much difference. Therefore, it can be concluded that Body Length (BL) Body Height (BH), and Chest Circumferences (ChC) are related to the type of birth while Canon Circumferences (CC) and Head Length (HL) performance are not related. Goat’s body performance is influenced by environmental conditions and animal feed.

This study was carried out to determine the concentration of arsenic, nickel, cadmium and chromium in the water, sediments and fish from Atani, Bridgehead and Otuocha segments of river Niger. The results indicated that arsenic concentration in the water, sediments and fish from the three segments were highest compared to other heavy metals analysed. Chromium was not detectable in the water, sediments and fish samples from the three segments. The order of the concentrations of the heavy metals from this results showed that in all the segments (As>Ni>Cd>Cr). Heavy metals accumulated in the water, sediments and fish which indicate contamination of the river and the need to control the source of pollution of these water bodies.

Granulomatosis with polyangiitis (GPA), formerly called Wegener's granulomatosis, is a rare systemic disease of unknown etiology that can affect all areas of the body, including the oral cavity. Typical oral manifestations present as nonspecific erosive/ulcerative lesions of the oral mucosa or appear with hyperplastic gingivitis, termed “strawberry gingivitis”. We report here a case of cheek ulceration as the first sign of recurrence of GPA in the absence of oral manifestations in the primary disease. A 37-year-old woman was referred to our oral pathology and surgery department for oral ulcerations. The patient had already been diagnosed with GOODPASTURE syndrome (pneumorenal syndrome) two years previously and treated with cyclophosphamide and Azathioprine. Its relapse and the appearance of oral manifestations made it possible to readjust the diagnosis and the treatment.
