Introduction: The purpose of this study was to prove the effect of administering Moringa leaf ethanol cream extract in inhibiting the increase in tyrosinase level and the amount of melanin in the skin of male guinea pigs (Cavia porcellus) exposed to ultraviolet-B (UVB).
Methods: This research was an experimental study using a randomized post-test only control group design method. The research subjects were 30 male guinea pigs divided randomly into five groups: group without cream, group with basic cream, group with 5%, 10% and 20% Moringa leaf ethanol cream extract. The five groups were exposed to UVB lamps for 15 days, and skin samples were taken 48 hours after the last exposure to UVB to examine the amount of melanin using Masson Fontana staining and tyrosinase enzyme using ELISA method.
Results: The best reduction in tyrosinase enzyme was in the group given 20% of Moringa leaf extract cream (10.63 ± 6.53 ng/mL) with a p value of 0.004 (p<0.05). Based on the amount of melanin, the highest mean amount of melanin was found in the group without cream (37.40 ± 16.77) and the lowest was in the treatment group given 20% Moringa leaf cream extract (10.63 ± 6.53) with a p value of 0.008 (p<0.05).
Conclusion: Administration of Moringa leaf (Moringa oleifera L.) ethanol cream extract inhibits the increase in tyrosinase enzyme level and the amount of melanin in the skin of male guinea pigs (Cavia porcellus) exposed to UVB with an appropriate concentration for safe use of the cream is between 5% and 10%.

Notable variants of SARS COV 2 Virus - A Mini-Review
Authors: E. Lawani-Luwaji , T. Alade , B.U. John
Published: November 2023

Viruses undergo mutations over time, and sometimes these changes do not have any significant impact on the virus's properties. However, certain mutations can alter the way the virus interacts with the host's major components, leading to modifications in the host's machinery within the cell. These modifications can affect the virus's properties, such as its transmissibility, severity of the disease, effectiveness of therapeutic medications, vaccines, and other social and public measures related to health. This review paper aims to discuss the different variants of SARS-CoV-2 that have emerged since the first documented case of the virus. We searched for keywords such as severe acute respiratory syndrome coronavirus 2 and variants on websites like the World Health Organization and databases like PubMed, Medline, and blogs. We examined these sources to find relevant materials published on the topic. The variants are classified based on ancestry and segment mutations, and they are grouped into distinct categories based on their potential for causing severe disease. The identification of five notable variants since December 2020, namely the Alpha, Beta, Gamma, Delta, and Omicron variants, has blown up the virus lineages. These variants have added complexity to COVID-19 research and have required extra epidemiological, laboratory, and clinical research avenues.

Authors: Dr. Vasu BA, Srinivas G, Divya R Dr. Vanitha B, Dr Neelima M,
Published: November 2023

Emotional intelligence (EI) plays a significant role in shaping organizational commitment among college teachers. College faculty members often work in dynamic and demanding environments, where interpersonal relationships and effective communication are crucial. This heightened emotional awareness and regulation not only enhance their ability to establish positive working relationships but also contribute to a more positive and supportive work environment. When college teachers feel valued, understood, and supported, their commitment to the organization increases. They are more likely to align themselves with the institution's mission and goals, which, in turn, can result in greater job satisfaction and a willingness to invest in their long-term career with the college. In essence, emotional intelligence fosters a sense of belonging and attachment to the organization, which is a critical component of organizational commitment. Institutions that promote emotional intelligence and provide training and support in this area can foster a more engaged and committed faculty, ultimately benefiting both the teachers and the institution as a whole.

Seventeenth-century Poetry and the Baroque Space: George Herbert, John Donne and Elizabeth Bishop
Authors: Cheema Amna Umer
Published: November 2023

This article examines Elizabeth Bishop’s relationship with the metaphysical poetry of George Herbert and John Donne demonstrating a baroque consciousness in Herbert’s and Donne’s poetry. This consciousness is found in Counter-Reformation artworks and popular reform texts, such as St. Ignatius Loyola’s The Spiritual Exercises, in conjunction with the seventeenth-century’s cosmological findings of the plurality of the universe. In responding to these poets’ works, this article introduces some of Bishop’s poems that exemplify the baroque style of poetry as a spatial form, exhibiting a plural expanse that can spatialize innumerable secular ideas in the manner of cosmic dimensions of motion. I argue that Bishop shares Herbert’s and Donne’s familiarity with St. Ignatius, demonstrating her reading of The Spiritual Exercises through her poem “The Weed.”

A Marine Bacterium with Animal-Pathogen-Like Type III Secretion Elicits the Nonhost Hypersensitive Response in a Land Plant
Authors: Lee Boyoung , Lee Jeong-Im , Kwon Soon-Kyeong , Ryu Choong-Min , Kim Jihyun F.
Published: December 2023

Active plant immune response involving programmed cell death called the hypersensitive response (HR) is elicited by microbial effectors delivered through the type III secretion system (T3SS). The marine bacterium Hahella chejuensis contains two T3SSs that are similar to those of animal pathogens, but it was able to elicit HR-like cell death in the land plant Nicotiana benthamiana. The cell death was comparable with the transcriptional patterns of H. chejuensis T3SS-1 genes, was mediated by SGT1, a general regulator of plant resistance, and was suppressed by AvrPto1, a type III-secreted effector of a plant pathogen that inhibits HR. Thus, type III-secreted effectors of a marine bacterium are capable of inducing the nonhost HR in a land plant it has never encountered before. This suggests that plants may have evolved to cope with a potential threat posed by alien pathogen effectors. Our work documents an exceptional case of nonhost HR and provides an expanded perspective for studying plant nonhost resistance.

Published: December 2023

Fusarium root rot is an increasingly severe problem in soybean cultivation. Although several Fusarium species have been reported to infect soybean roots in Heilongjiang province, their frequency and aggressiveness have not been systematically quantified in the region. This study aimed to investigate the diversity and distribution of Fusarium species that cause soybean root rot in Heilongjiang province over two years. A total of 485 isolates belonging to nine Fusarium species were identified, with F. oxysporum and F. solani being the most prevalent. Pot experiments were conducted to examine the relative aggressiveness of different Fusarium species on soybean roots, revealing that F. oxysporum and F. solani were the most aggressive pathogens, causing the most severe root rot symptoms. The study also assessed the susceptibility of different soybean cultivars to Fusarium root rot caused by F. oxysporum and F. solani. The results indicated that the soybean cultivar DN51 exhibited the most resistance to both pathogens, indicating that it may possess genetic traits that make it less susceptible to Fusarium root rot. These findings provide valuable insights into the diversity and distribution of Fusarium species that cause soybean root rot and could facilitate the development of effective management strategies for this disease.

Published: December 2023

Botrytis cinerea is a major fungal plant pathogen that causes gray mold disease in strawberries, leading to a decrease in strawberry yield. While benzimidazole is widely used as a fungicide for controlling this disease, the increasing prevalence of resistant populations to this fungicide undermines its effectiveness. To investigate benzimidazole resistant B. cinerea in South Korea, 78 strains were isolated from strawberries grown in 78 different farms in 2022, and their EC50 values for benzimidazole were examined. As a result, 64 strains exhibited resistance to benzimidazole, and experimental tests using detached strawberry leaves and the plants in a greenhouse confirmed the reduced efficacy of benzimidazole to control these strains. The benzimidazole resistant strains identified in this study possessed two types of mutations, E198A or E198V, in the TUB2 gene. To detect these mutations, TaqMan probes were designed, enabling rapid identification of benzimidazole resistant B. cinerea in strawberry and tomato farms. This study utilizes TaqMan real-time polymerase chain reaction analysis to swiftly identify benzimidazole resistant B. cinerea, thereby offering the possibility of effective disease management by identifying optimum locations and time of application.
Principle and application of random walk simulation: Multilayer networks, predation and stock market
Authors: Yang Yufei
Published: November 2023

Given the probabilities (which remain unchanged at each step) of travelling a certain distance in a certain direction, a random walk is a method used in probability theory to determine the likely position of a point depending on random movements. Markov processes, in which future behavior is independent of previous behavior, include random walks as an illustration. This study will mainly pay attention to three different applications of random walks in aspects of multilayer networks, predation and stock market. A real and intricate network could be solved by a mathematical equation depending on a random walk model. There are totally four different types of random walks that properly represent the motion of an animal searching for preys. Among these four types, CCRW is the best explanation for the route of a predator. Nevertheless, by analyzing the panel unit root tests, random walks fail to simulation the variability of share prices. This study promotes scholars to come up with an idea of the principle and application of random walks, and therefore realize the significance of such simulations.

Mechanisms and advantages of the variable cycle engine
Authors: Li Yifu
Published: November 2023

Designed for aircrafts to fly mixed missions (i.e., at subsonic, transonic, and supersonic flight speeds) with low levels of fuel consumption, the variable cycle engine is ideal for many high-speed planes. The variable cycle engine has the characteristics of both a high-bypass engine (for subsonic flight speed) and a low-bypass engine (for supersonic flight speed). As modern jet engines develop, they inevitably face a bottleneck. Therefore the VCE is seen by most as the next stage of the engines. More and more companies are beginning to invest in this new technology. This paper is targeted to explore the basic mechanism of various VCEs and to see how this new engine brings people better performance over conventional jets. Through Documental Analysis and case study, this research discovered the variable cycle engine greatly improves efficiency and reduces heat of the exiting exhaust in subsonic flight and generates higher thrust during afterburner.

The conversion rate from oil to gasoline is low, which is not conducive to the utilization of raw materials. There are many unavoidable losses during the transportation of oil. The conversion rate of traditional engines in automobiles is very low, and it cannot be improved in a short period of time. The exhaust gases emitted by conventional engines can cause serious pollution to the environment. In contrast, China has abundant power resources, and the loss of electrical energy in the transmission process is also very small. Pure electric vehicle engines are highly efficient and have the potential for further improvement. Brake energy recovery is also an important part of improving efficiency. Pure electric engines bring little pollution to the environment.

The development of integrated circuits has gone through several stages, from the invention of transistors to the emergence of very large scale integrated circuits and system level integrated circuits. Now, the size of integrated circuits enters the nanometer level, and short-channel shot noise becomes an important issue. Short-channel shot noise increases due to factors such as device size reduction and scattering during channel formation. It has a serious impact on the performance, power consumption and reliability of integrated circuits. The formation mechanism of short channel shot noise can be explained from two aspects: one is due to the existence of thermal noise inside the channel, and the other is due to the noise caused by the shot. As the device size decreases, the channel thermal noise gradually changes into shot noise and becomes one of the main noise sources. Aiming at the noise generation mechanism, this paper proposes several methods to solve the short-channel shot noise. Through the research of short-channel shot noise and the exploration of solutions, the impact of shot noise on IC performance can be better understood and dealt with, and the development and innovation of IC technology can be promoted.

In the construction industry, technology-based Artificial Intelligence (AI) has become the center of development. AI image recognition technology has been developed and applied to face various application scenarios on the construction site and help workers increase their efficiency and accuracy in recognized work. The purpose of this paper is to introduce two mature AI technologies: the reinforcement quantity identification system and the intelligent identification and evaluation method of typical damages to a fair-faced wall. The reinforcement quantity identification system uses the method to train a model on the Yolo v3 algorithm. It is able to help workers use an image taken to get the number of bars to be counted. The intelligent identification and evaluation method to a fair-faced wall is designed to focus on the three typical damages, weathering, efflorescence, and plant coverage. In the design model, the used algorithm is Yolo v4, and OpenCV is applied as a vision library to access the degree of damages. Workers only need to upload an image to the system, and then it will return an analysis result for the wall. Through this paper, readers will understand their main algorithms and models based on AI technology, as well as their practical applications in the construction industry, and provide a theoretical introduction for future AI image technology references.
