Effects of Allanblackia floribunda stem-bark Extracts on Oxidative stress and Mitochondrial Dysfunction in Rats Exposed to Crude Oil
Authors: Olubodun Stella , Ikponmwosa-Eweka Omorede 
Published: August 2022

The development of degenerative diseases has been linked to oxidative stress and mitochondrial dysfunction. Additionally, it has been demonstrated that the changes caused by crude oil exposure contribute to the onset of degenerative diseases. There is little or no information on the anti-degeneration properties of Allanblackia floribunda. This study was carried out to investigate brain mitochondrial tissues exposed to crude oil and the effects of A. floribunda as a preventive and therapeutic intervention against oxidative stress and mitochondrial dysfunction. Twenty-five Wistar rats were divided into five groups: the control group received distilled water, the second group received ethanol extracts of A. floribunda, the third group received crude oil (5 mL/kg), the fourth and fifth groups received crude oil and A. floribunda extract concurrently (200 and 400 mg/kg, respectively). The results showed that crude oil treatment caused a significant increase in brain mitochondrial MDA levels and induced significant alterations in brain mitochondrial antioxidant enzyme activities compared with control. Treatment with the extract alone revealed a significant increase in protein carbonyl, conjugated dienes, and ATPases compared with crude oil-treated rats. This indicates that A. floribunda inhibited crude oil-induced mitochondrial lipid peroxidation and improved ATPase and antioxidant status in the rat brain mitochondria, which further suggests that A. floribunda possesses potential and may efficiently inhibit crude oil-induced oxidative damage and improve mitochondrial functions.

The study aimed at comparing the resolution and effectiveness of three-electrode arrays (Wenner-α, Wenner-β, and Wenner-γ) in the 2D Electrical resistivity method using Numerical analysis of geological models. Three synthetic geological models that simulate block-one dyke and water layer were generated using RES2DMOD software. The inversion used for the geological models was based on smoothness-constrained least-square inversion which was carried out with RES2DINV. The inversion results were imputed into surfer11 software to examine the image resolution, thereafter absolute percentage error (APE) was calculated to measure the effectiveness of the arrays. The result for the block-one model shows that the Wenner-β array has an APE of 14.45%, the Wenner-α array has an APE of 32.67%, and the Wenner-γ array with an APE of 29.15%. Similarly, for the dyke model, the Wenner-α array, Wenner-β array, and Wenner-γ array have an APE of 69.61%, 57.43%, and 45.49% respectively. However, the results for the water layer model show that the Wenner-α array has an APE of 17.11%, the Wenner-β array has an APE of 12.16%, and that the Wenner-γ array has an APE of 16.21%. Wenner-α is expected to produce an image with the best resolution having the highest APE, henceforth APE suggests the resolution capacity of an array.

Cassia occidentalis commonly known as Coffee senna is a herbaceous plant that belongs to the family fabaceae. The plant is called “Sanga-Sanga" in Hausa, “Ewe Oriesi” in Yoruba, and “Akidi Agbara” in Igbo. Coffee senna is a pan-tropical plant. This research was aimed at evaluating the phytochemicals and antibacterial activity of extracts of leaves of Coffee Senna. Plant leaf samples were collected behind Department of Biological Sciences Federal University Gusau. The samples were air dried and grounded into powder using mortar and pestle. The phytochemical analysis of both methalonic and aqueous leaf extracts revealed the presence of Cardiac glycosides, Steroids, Flavonoids, Alkaloids, Saponin glycosides, Saponins glycosides, Tannins and Anthraquines. Volatile oils, Balsams and glycosides were absent in the extracts. Methanolic and aqueous extracts of leaves of Cassia occidentalis were screened for their antimicrobial activity against two bacterial strains by disk diffusion assay. The pattern of inhibition varied with the solvent used for extraction and the microorganism tested. Among these extracts, methanol and aqueous extracts showed significant antimicrobial activity against the tested microbes. The most susceptible microorganism was Salmonella typhi 22 mm zone of inhibition in both the extract (Methanol and aqueous extract), then, followed by Streptococcus epidermidis with 20 mm zone of inhibition in both the extract (Methanol and Aqueous). The study concludes that Senna occidentalis leaf extracts studied showed high inhibition of bacterial growth, therefore the plant can be used in ethno-medicine and the pharmaceutical industries.

Abstrak: Jaringan tanpa kabel (Nirkabel) atau sering dikenal dengan WI-FI ini berkembang sangat pesat dengan memanfaatkan daya jangkau sinyal yang besar dalam ruangan, ataupun luar ruangan dengan jangkuan yang sangat jauh. Komunikasi radio HF Near Vertical Incident Skywave (NVIS) mampu mengatasi skip zone sehingga tidak mempengaruhi kwalitas pancaran, apakah padang rumput, hutan lebat, lereng gunung dan sebagainnya. NVIS adalah pemantulan satu kali oleh lapisan F/F2 ionosfer, dengan pancaran (sinyal) radio untuk komunikasi HF dengan memancarkan sudut pancaran yang nyaris tegak lurus (Near Vertical) ke atas mendekati 90 º.[1]. MMANA adalah software untuk mensimulasi antenna yang dibuat oleh JE3HHT - Makoto Mori, DL1PBD - Alex Schewelew & DL2KQ – Igor Gontcharenko. Program software MMANA-Antenna Analyzer pertama kali diciptakan oleh Macoto Mori – JE3HHT, seorang amatir radio dari Jepang (10 Januari 1999). Kemudian dikembangkan oleh Alex Schewelew (DL1PBD) dan Igor Gontcharenko (DL2KQ) keduanya amatir radio dari German.[3] Menggunakan software MMANA kita dapat menghitung secara tepat berapa ukuran antenna yang harus kita bangun untuk bekerja pada frekuensi tertentu yang match dan baik. Hasil yang di harapkan dari penelitian ini adalah simulasi perancangan antena radio HF NVIS dapat dipakai untuk komunikasi jarak dekat yag terlewati (Skipzone) dan mmapu digunakan di daerah yang sulit dijangkau sinyal.Kata kunci: Frekuensi 10 MHz, Anlisis aplikasi MMANA, Radio HF NVISAbstract: Wireless network (Wireless), often known as WI-FI, is overgrowing by utilizing a large signal coverage indoors or outdoors with a very far reach. HF Near Vertical Incident Skywave (NVIS) radio communication can overcome the skip zone so that it does not affect the quality of the beam, whether it is grasslands, dense forests, mountain slopes, and so on. NVIS is a one-time reflection by the ionospheric F/F2 layer, with a radio beam (signal) for HF communication by emitting a near vertical beam angle upward approaching 90 º. MMANA is a software for simulating antennas created by JE3HHT - Makoto Mori, DL1PBD - Alex Schewelew & DL2KQ – Igor Gontcharenko. Macoto Mori first started the MMANA-Antenna Analyzer software program – JE3HHT, a radio amateur from Japan (10 January 1999). It was later developed by Alex Schewelew (DL1PBD) and Igor Gontcharenko (DL2KQ), both radio amateurs from Germany. Using MMANA software, we can calculate precisely how much antenna size we have to build to work at a specific frequency that matches and is good. The expected result of this research is a simulation of the design of an HF NVIS radio antenna that can be used for short-range communication that is skipped (Skipzone) and used in areas that are difficult to reach signals.Keywords: Frequency 10 MHz, MMANA application analysis, HF NVIS Radio

CULTURAL ASPECTS REPRESENTATION IN ENGLISH TEXTBOOK AND ITS IMPLICATION ON ENGLISH LANGUAGE LEARNING
Authors: Ariawan Soni 
Published: August 2022

Abstract. The present study investigates cultural aspects representation in an English textbook prescribed for senior high school in Indonesia which is officially published by Ministry of Education and Culture in 2017. The study aims to explore cultural aspects revealed in the textbook by employing Byram’s checklist of cultural dimensions and Cortazzi and Jin’s categories of culture as the theoretical frameworks. The data for analysis is selected from the textbook which includes conversations, reading texts and visual elements. The inclusion of national identity is pivotal for learners since the textbook is prescribed for senior high school students who are tremendously curious to determine their own characters. Regarding cultural aspects representation or categories, source culture or Indonesian culture is the most prominent with 61.2%, while target culture and international target culture achieve 19.8% and 14.9% respectively. The presence of source culture encompasses social interaction, school and family environment, national identity and national history as well as national geography. Where the target culture is concerned, the United States of America is the most highly represented inner circle country’s culture in the textbook, while India and Japan are the countries primarily represented in the international target culture category. The inclusion of source culture in the English textbook is fundamental since culture teaching can improve learners’ communicative competence; however, the representation of target culture and international target culture is also crucial to achieve linguistics as well as cultural competence. It is concluded that English textbook in Indonesia is on the way to its perfection in terms of proportionally represented cultural aspects. However, the presence of various cultural aspects of source culture, target culture and international target culture is also important to help students develop multicultural awareness and a certain level of respects as well as tolerance for others. in the use of student’s diary as well is presented as the implication of this research for further related studies.

Compliment responses are one of speech act types in pragmatic study. This study is aimed (1) to investigate the strategies used by the American and Makassarese people in responding to the complim ent, (2) to compare the response tendencies used by American and the Makassarese people based on Gender and age; and (3) to investigate the cultural influences on the American and Makassarese response.The research was a comparative study which and used a descriptive- qualitative approach. The data were collected from youtube.com and DCT questionnaire. The data were analyzed using a number of techniques, namely noting down the utterances, categorizing the responses identified based on Holmes’ semantic formula and explaining the cultural influences based on their responses. Firstly, the research result revealed that both the American and Makassarese people used 3 compliment strategies: accepting, evading and refusing. Americans would use the evading strategy when the speaker and his interlocutor were good friends; while a Makassarese would either use the evading strategy or the refusing strategy in his responses, when the speaker and his interlocutor were of a different kinship hierarchy, such as between the older and the younger brothers or sisters and between husband and wife. Secondly, The comparison of the compliment responses between the American and Makassarese males indicated that an American male had the tendency to evade a compliment in every topic except teenager had tendency to accept the compliment in any topic. While a Makassarese male tend to receive the compliment for all the topics, except for the comp liment for an achievement.on the other hand, an American woman had tendency to accept a compliment for all topics, but an older woman had a tendency to refuse a compliment. a Makassarese woman, had also a tendency to accept a compliment for all topics. Finally, Makassarese people, both men and women had the tendency to accept, evade or refuse compliments when they had kinship.

Fashion by Design
Authors: Ellinwood Janice Greenberg 
Published: August 2022

Fashion by Design, Second Edition, explains how the elements and principles of design relate to fashion, based on the philosophy of the Bauhaus Experiment of the 1920s and 1930s, which is the foundation for art education in the United States. The book is structured into three parts: the stages of the design process (inspiration, identification, conceptualization, exploration/refinement, definition/modeling, communication, and production); physical elements (such as line, shape, form, space, texture, light, pattern, color, and value); and theoretical principles (like balance, emphasis, rhythm, proportion, and unity) of design. This is reinforced by fashion designer profiles and illustrations covering art, architecture, and fashion. The book aims to improve the designer’s eye for creating fashion and related art forms; to identify terminology used in the communication of fashion; and to show how other factors, such as the human form, clothing structure, historic silhouettes, fashion trends, culture, and industry trends, may impact the development of a line or a collection.
New to this Edition:
- New introductory chapter on the stages of the design process
- New chapter on sustainable design
- New end-of-chapters exercises with application to the fields of fashion design (including the development of a design journal), fashion merchandising (such as styling, product development, buying or trend research) and theater arts (such as costume, sets, lighting)
