Automated Grassweed Detection in Wheat Cropping System: Current Techniques and Future Scope

Abstract:

Wheat is a staple grain crop in the United States and around the world. Weed infestation, particularly grass weeds, poses significant challenges to wheat production, competing for resources and reducing grain yield and quality. Effective weed management practices, including early identification and targeted herbicide application are essential to avoid economic losses. Recent advancements in unmanned aerial vehicles (UAVs) and artificial intelligence (AI), offer promising solutions for early weed detection and management, improving efficiency and reducing negative environment impact. The integration of robotics and information technology has enabled the development of automated weed detection systems, reducing the reliance on manual scouting and intervention. Various sensors in conjunction with proximal and remote sensing techniques have the capability to ca...

A Network Pharmacology-Based Strategy For Predicting Therapy Targets Of Beta-Sitosterol In Treating Diabetic Retinopathy

Abstract:

Beta-Sitosterol (SIT) is an active TCM compound employed to treat diabetic retinopathy (DR). A network pharmacology approach to understanding the active ingredients and the therapeutic mechanisms underlying DR has not been pursued.

Response of Sorghum Varieties to Organic and Inorganic Fertilizer Strategies in Sudan Savanna of Nigeria: Productivity, Nitrogen, and Water Use Efficiencies

Abstract:

Experiments were conducted to evaluate the response of different sorghum varieties to micro-dosing fertilization strategies on yield and yield traits, as well as the impact on nitrogen fertilizer and water use efficiency (NUE and WUE). In addition, the benefit-cost ratio of sorghum cultivation under different fertilization strategies in the Sudan savanna zone of Nigeria was analyzed. The experiment included eight fertilizer micro-application strategies as well as two control and three sorghum varieties. Our results showed that most agronomic indicators differed significantly between years, varieties, and fertilization strategies. However, the application of 100g hill^-1 poultry manure plus 3g NPK hill^-1 resulted in the highest average grain yield > 2000 kg ha^-1 at both study sites (BUK and Minjibir). This means that the grain yield is 86% and 132% higher than the ...

Peptide Synthesis in Aqueous Solution With a Reusable Solid Phase

Abstract:

A procedure has been developed for synthesizing peptides in an aqueous solution with a reusable solid phase. Specifically designed linker molecule is employed to attach peptides to hydrophilic solid phases, enabling Solid Phase Peptide Synthesis (SPPS) in aqueous solutions. The linker molecule is utilized to connect peptides to an anionic exchange resin during peptide synthesis in an aqueous solution. The general structure of the linker molecule is Fmoc-AA-CH2-Ph-Rx-SO₃^-, the Fmoc (9-fluorenylmethoxycarbonyl) group serves as a protecting group for amino acids. Amino acids (AA) are linked to the solid phase through a structure of Methoxyphenylcarbonyl group, which is cleavable under strong acidic conditions. The sulfate group is present for forming an ionic bond with the solid resin in an aqueous solution. In this procedure, Fmoc-AA are utilized as building blocks for sequentially adding ami...

Quantum Approach to Allergic Pathology

Abstract:

Allergy, despite its stereotyped symptomatic manifestations, continues to pose significant etiological, pathophysiological, and therapeutic challenges. In the interface between the body and the environment, the respiratory pathway is particularly stressed from an allergological perspective. Under the relationship between energy and matter signed by Einstein, it is possible to approach patients suffering from allergies with an Electraceutical 1 administration in a quantum modality.

Fecal Shedding, Antimicrobial Resistance and In Vitro Biofilm formation on Simulated Gallstones by Salmonella Typhi Isolated from Typhoid Cases and Asymptomatic Carriers in Nairobi, Kenya

Abstract:

Typhoid fever, caused by the human restricted pathogen Salmonella Typhi, remains a major global public health concern. Even after successful treatment, approximately 3-5% of patients with typhoid fail to clear the bacteria within one year and become chronic carriers. Most typhoid carriers have gallstones in their gallbladder, and biofilm formation on gallstones is highly correlated with chronic carriage. This study’s goal was to identify asymptomatic typhoid carriers in an endemic setting in Kenya, and to compare acute versus chronic isolates. A cohort of typhoid fever patients identified through blood and/or stool culture, and their household contacts, were followed up after treatment to detect longitudinal S. Typhi stool shedding. An abdominal ultrasound scan was used to identify individuals with gallstones. A total of 32 index patients and 32 household contacts were successfully followed-up. Gallstones were ...

Edpidemiology, Clinical Profile and Short- Term Outcome of Hypertensive Crisis in N'Djamena (Chad)

Abstract:

Hypertensive crisis is an increasingly frequent medical condition in our context. Its management in medical emergencies is a real challenge for physicians. Few data on hypertensive crisis are available in Chad. The aim of this study was to investigate the epidemiological, clinical and prognostic characteristics of hypertensive crisis in the medical emergency department of Reference National Teaching Hospital in N'Djamena.

Sesame (Sesamum indicum L.) seeds and di ammonium phosphate (dap) potential for controlling Striga seed germination, sorghum growth and grain yield

Abstract:

Sorghum is important staple food for feeding humans and animals in sub-Saharan African country. Nowadays, with the advent of climate change couple to the population growth, the crop is faced to new challenges wish are gradually affecting the productivity. In Niger, a dry land country where farmers are growing sorghum at a small scale for family subsistence, the crop is confronted to biotic and abioticonstraints including nutrient deficiency in the soil. Among those constraint, Striga is the one that causes huge damage to sorghum cultivation through yield reduction. In addition, nutrient depletion in the soil are causing weed progresses in farmer’s field at a large scale. In fact, to overcome Striga problem several control methods have been successfully tested, but some of them are efficient but not accessible to farmers. It is important to control the weed by using effective and accessible way for smallholder farme in Niger. The main objective of ...

Measuring Quality Change in the Market for Anti-Ulcer Drugs

Abstract:

The General Accounting Office released a study in August 1992 of twenty-nine sampled prescription drugs that reported an average increase in the price of approximately 138 percent between 1985 and 1991 (GAO 1992, 4, Table 1) Those and other published price indexes are increasingly being used in the public policy arena to focus the debate on the potential regulation of pharmaceutical prices and the coverage of health insurance. In an industry where products are multidimensional and the rate of technological progress is brisk, misinterpretation of unadjusted indices of drug prices can easily arise. This can lead to erroneous conclusions regarding appropriate policies for the pharmaceutical industry.

Researchers have addressed numerous general theoretical issues concerning the construction and interpretation of price indices 1. Two issues of particular ...

Exploring HIV Self-Testing: Barriers and Facilitators among Undergraduate Students

Abstract:

Globally, 36.7 million individuals live with HIV/AIDS, with 2.5 million new cases annually. Youth (14-25 years) account for 45% of these new infections. Those aged 15-24 years are less likely to be aware of their HIV status and engage in HIV care compared to older adults. This study explores the use of HIV self-testing to improve access to HIV care among Kenyatta University undergraduates.
