Sudan low changes affecting rainy days in southwestern Iran over six decades (1957–2019)
Authors: Mohammadi Fahimeh , Pazhoh Farshad , Hombari Farzaneh Jafari
Published: December 2021

The present study evaluated the dynamic changes in Sudan low systems over six decades (1957–2019), which were classified based on solar cycles. Rainfall days were extracted in January using data from 42 synoptic stations in the south and southwest regions of Iran. Then, the rainy days due to the Sudan low system were separated from the precipitation of the other atmospheric systems using the visual analysis of the maps. The synoptic analysis indicated that the sea level pressure has been decreasing at all sampling stations from the first to the sixth decade. Furthermore, decreasing elevation to −80 m (negative anomaly) in the 500 hPa level atmosphere from the first decade to the sixth decade indicated further atmospheric instability and more strengthening of the Sudan low compared to previous decades. The contribution of advection moisture to the area increased within the region at 700 hPa. This implies that the role of the transferred moisture from the intertropical convergence zone is increasing in the systems transferred from Sudan and in the study area. In general, the share of Sudan low precipitation is increasing in the south and southwest regions of Iran. This result is a positive effect of the climate change on the study area.

Authors: Qin Yu , Yu Zongtai , Gou Yujia , Liu Zhengmian
Published: December 2021

This study selected five points in the middle and upper mainstream of the Three Gorges Reservoir area. Starting from May 2016, the greenhouse gases CO2 and CH4 from the water–air formation at the sampling points have been monitored month by month for 10 months. Using the headspace balance method and the thin boundary layer model estimation method, we obtained the CO2 and CH4 partial pressure ranges and the water–air formation diffusion flux at the mainstream point. It is found that the CH4 partial pressure of water body is significantly positively correlated with water temperature, and significantly negatively correlated with DO; the CH2 partial pressure of water body is positively correlated with water temperature, but negatively correlated with conductivity, DO, pH and wind speed. The diffusion fluxes of CH4 and CO2 at the water–air formation are positively correlated with CH4 partial pressure and water temperature, and negatively correlated with ph, DO and conductivity. It is also found that the reservoir has a certain mitigation effect on the release of CO2 from the river water body, and the CH4 diffusion flux at the water–air formation is roughly equivalent.
Críticas ao Estruturalismo na virada do século
Authors: Rodrigues Schechner Caio
Published: December 2021

Em 2001, Claude Lévi-Strauss, figura central para as Ciências Sociais, publicou no periódico L'Homme uma resenha do terceiro volume sobre a América do Sul da coletânea The Cambridge History of the Native Peoples of the Americas, organizado por Frank Salomon e Stuart B. Schwartz. Os organizadores responderam às acusações em duas oportunidades distintas: uma delas, assinada apenas por Schwartz, saiu em 2002 pela The Americas, enquanto a outra, já assinada por ambos autores, apareceu na mesma L'Homme em 2003. O debate travado nas páginas desses periódicos será útil para retomar as contribuições do estruturalismo para a História e as Ciências Sociais, especialmente no que tange ao estudo dos povos indígenas.
Caminhos Indígenas
Authors: BELIK DANIEL
Published: December 2021

Esse artigo visa, por meio de exemplos históricos e etnográficos, tentar compreender a forma como os indígenas na Amazônia constroem as experiências espaciais na floresta percorrendo os caminhos. Muitos estrangeiros penetraram a Amazônia seguindo os cursos dos rios principais, pouco podendo informar sobre o espaço dos divisores de águas que se estendem entre os rios. Para isso, foi necessário se deixar levar por guias, intérpretes e remeiros indígenas (Kok, 2009; Roller, 2012) que conheciam a movimentação pelos caminhos na floresta. Baseado em Ingold (2000; 2010) comparo que enquanto a experiência de caminhar na floresta sempre foi parte integral da vida dos povos indígenas; para quem penetrou a selva vindo de fora, a floresta foi vista de modo utilitário, como caminhos a serem abertos e distâncias superadas.
Transformação dos espaços indígenas coloniais
Authors: Vicente Marcos Felipe
Published: December 2021

Desde os tempos coloniais, os espaços e territórios indígenas têm sofrido inúmeras transformações e drásticas reduções ao longo do tempo. Ainda nos primeiros anos do contato, os modos de produção, reprodução e apropriação dos espaços foram se modificando, dando origem a novos modelos. Perceber a dinâmica dessas transformações é um desafio aos estudiosos da temática indígena. Para tanto, faz-se necessária a construção de um arcabouço teórico-conceitual que possibilite analisar e compreender como os espaços vão se modificando e os territórios vão se constituindo a partir da situação colonial. Este ensaio propõe uma reflexão sobre os conceitos de território, territorialidade e suas variações para o estudo desses processos.

Published: December 2021

Como desdobramento de um trabalho publicado anteriormente, buscando refletir sobre as estratégias utilizadas no Ensino da Música na Educação Básica, a partir do diagnóstico de que os alunos tinham contato com a música apenas como ouvintes, a supervisora, juntamente com os bolsitas do PIBID/Música – UFRN, (re) planejaram e aplicaram o projeto “Rock`n Roll: despertando a expressão e criatividade musical dos alunos”. O público alvo foram três turmas do 3º ano do Ensino Fundamental da Escola Municipal Professora Maria Cristina Ozório Tavares. Tivemos como principal objetivo relatar a experiência do fazer musical no estilo Rock`n Roll, refletindo sobre a prática pedagógico-musical. Iniciamos assistindo e discutindo, através de um questionário, o filme “Escola de Rock”. Depois decorremos a estudar os principais instrumentos musicais do estilo. Os participantes exploraram seus corpos e objetos ao praticarem percussão corporal e jogo de copos e mão, e até criaram uma coreografia ritmada com os conhecimentos adquiridos numa das músicas símbolo do Rock`n Roll intitulada “We Will Rock You”. Assim, foram mudando a postura de apenas ouvintes passivos para exploradores sonoros, numa infinidade de estratégias que desenvolveram elementos musicais como percepção de diferentes estilos, ritmo e melodia, como também expressão e criatividade. Os alunos entenderam que existem muitos estilos de músicas, que o Rock`n roll era para desafiar o homem. Aprenderam que, para fazer música não dependemos exclusivamente de instrumentos convencionais, podemos utilizar o próprio corpo, ou objetos do cotidiano. Aprenderam também a utilizar a música em benefício individual e coletivo, e a respeitar gostos e estilos.

Published: December 2021

Introdução: A palavra “Jiu-Jitsu” tem como significado arte suave, tendo como seu principal objetivo, vencer o oponente colocando-o em risco iminente de lesões, apesar de não possuir movimentos considerados violentos. As áreas mais frequentemente acometidas por lesões são as articulações de joelho, cotovelo e dedos da mão. Objetivo: Estabelecer o perfil de lesões relacionadas a prática esportiva dos participantes do 1º open de Jiu-jitsu da cidade de Santa Cruz – RN. Metodologia: trata-se de um estudo observacional analítico de caráter transversal desenvolvido como parte de um projeto de extensão a partir da aplicação de questionário estruturado com os participantes do evento. Resultados: Foram avaliados 69 atletas dos quais 95,7% eram do sexo masculino e 4,3% do sexo feminino, com média de idade de 20,49±6,69 anos. A maioria dos atletas foram considerados amadores pois praticam a modalidade a menos de um ano (42%) e 42% relataram já ter sofrido alguma lesão relacionada ao esporte, sendo o joelho o local mais referido como foco de lesão (14,2%), além disso, apenas 33,3% dos atletas afirmaram conhecer a atuação da fisioterapia esportiva. Conclusão: Apesar da prática esportiva ganhar espaço gradativamente na vida dos brasileiros, poucos o fazem com segurança ao passo que os índices de lesões ainda são elevados e poucos se preocupam em tratar essas afecções.

Authors: Salustino Felipe Henrique Cadó
Published: December 2021

O projeto de extensão “Memória da UFRN: rastros, olhares, lugares” propõe-se a localizar e identificar documentos e artefatos de ciência e técnica que apontem para questões relacionadas à memória material em espaços da Universidade Federal do Rio Grande do Norte (UFRN), bem como em relação à dimensão imaterial da memória, compreendendo o objeto como histórico e recuperando-o a partir das evidências deixadas em meio a contextos de produção administrativa e acadêmica de dois setores da instituição: TV Universitária (TVU) e Hospital Universitário Onofre Lopes (HUOL). Esta busca por uma memória institucional é motivada por uma emergência em deixar rastros para a história a partir dos sujeitos que a integram e o estabelecimento de identidades existentes nesses espaços, construídos em experiências solos ou compartilhadas pelos indivíduos. Com esta perspectiva, este trabalho foi formulado pela Coordenadoria de Ações Culturais, Museológicas e de Memória da PROEX, procurando construir um diagnóstico em torno do levantamento de artefatos e da memória social, ou seja, catalogando os objetos encontrados, realizando pesquisas históricas e, registrando, por meio de audiovisual, os depoimentos de servidores ativos e aposentados que atuaram e colaboraram para o desenvolvimento dos setores mencionados. Como resultados, obtivemos um levantamento de objetos de ciência e técnica que pertencem aos setores que participaram deste projeto e que fazem parte do itinerário histórico destas unidades suplementares da UFRN, o registro em audiovisual de depoimentos de pioneiros que fizeram parte da história das instituições e por fim um diagnóstico da memória das unidades suplementares após os registros dos resultados anteriores. Procuramos apontar as possibilidades de registros e visibilidade que representem a história da universidade e sua identidade, assim como registros a compreensão sobre a importância desses lugares estudados.

Human Cancers
Authors: Bahrami Afsane , Ferns Gordon A.
Published: December 2021

:

MicroRNAs (miRs) is a class of conserved, small, noncoding RNA molecules
that modulate gene expression post-transcriptionally. miR-148b is a member of miR-
148/152 family generally known to be a tumor suppressor via its effect on different
signaling pathways and regulatory genes. Aberrant expression of miR-148b has recently
been shown to be responsible for tumorigenesis of several different cancer types. This
review discusses the current evidence regarding the involvement of miR-148b
expression in human cancers and its potential clinical importance for tumor diagnosis,
prognosis, and therapeutics.
Physiological and Pathophysiological Role of Cysteine Metabolism in
Human Metabolic Syndrome
Authors: Muthuraman Arunachalam , Ramesh Muthusamy , Shaikh Sohrab A. , Aswinprakash Subramanian , Jagadeesh Dhamodharan
Published: December 2021

Cysteine is one of the major intermediate products of cellular amino-acid metabolism. It is a semi-essential amino acid for protein synthesis. Besides, it is also employed in the regulation of major endogenous anti-oxidant molecules i.e., reduced glutathione (GSH). Further, it is a precursor of multiple sulfur-containing molecules like hydrogen sulfide, lanthionine, taurine, coenzyme A and biotin. It is also one of the key molecules for post-translational modifications of various cellular proteins. In physiological conditions, it is employed in the sulfhydration process and plays a key role in the physiology modification of the inflammatory process in various organs, including the neurological system. The catabolism of cysteine is regulated by cysteine dioxygenase enzyme activity. The dysregulated conditions of cysteine and cysteine-associated hydrogen sulfide metabolism are widely employed in the acceleration of the neurodegenerative process. Moreover, the upregulation of cysteine and hydrogen sulfide synthesis occurs via the reverse trans-sulfuration process. This process helps to manage the worsening of a pathological condition of a cellular system. Moreover, it is also employed in the accumulation of homocysteine contents. Further, both cysteine and homocysteine molecules are widely accepted as biomarkers for various types of diseases. Therefore, the targets involved in the regulation of cysteine have been considered as valid targets to treat various disorders like cardiac disease, ischemic stroke, diabetes, cancer, and renal dysfunction.
Differential Proliferative and Cytotoxic Effect of Selected Components of
Essential Oils on Human Glioblastoma Cells
Authors: Sheikh Sumbla , Sturzu Alexander , Kalbacher Hubert , Nägele Thomas , Ernemann Ulrike , Heckl Stefan
Published: December 2021

Background:

In the study of bioactive agents from traditional medicine, mono- and
sesquiterpenes represent the main ingredients of essential oils. Till now, only thymoquinone and
perillyl alcohol have been clinically tested on glioblastoma.

Objective:

In the present study, we examined the effect of ten different essential oils on three human
glioblastoma cell lines and one healthy human cell line.

Methods:

We used confocal laser scanning microscopy, flow cytometry, and cell growth analysis
to evaluate cell morphology changes, membrane disruption effects, acute cytotoxicity and effects
on the proliferation rate caused by the essential oils pinene, geraniol, eucalyptol, perillaldehyde, limonene,
and linalool, perillyl alcohol, myrcene, bisabolol and valencene on human cells. Caspase
3/7 activity was measured to observe apoptosis induced by the essential oils.

Results:

We found that the cytotoxicity concentrations varied not only between different essential
oils but also among different cell lines. Acute cytotoxicity of essential oils was based on cell membrane
disruption and that HEK cells were affected to a much higher degree than the Glioblastoma
cells. Vacuoles found in surviving glioblastoma cells appeared to be a factor in this effect.

Conclusion:

Caspase activity did not correlate with the membrane damage observed in the flow cytometry
experiments. This is especially evident in the HEK cells that only showed apoptosis with
two out of ten essential oils. Comparison of the effects of other essential oil to perillyl alcohol,
which is already used in glioblastoma therapy, revealed perillaldehyde and valencene as two new
candidate substances that showed even stronger anti-glioblastoma effects in all experiments.

Authors: de Lima Fernandes Maria Ayanny , de Aguiar Silva Andreza Tallyne , Cavalcanti Iago Dillion Lima , de Medeiros Adrya Lúcia Peres Bezerra , de Oliveira Lima Lígia Maria , de Castro Gomes Tâmara Kelly
Published: December 2021

Introduction:

The established dose of chemotherapy is based on the values of the patient's
body weight, where variations during treatment can increase the toxicity of chemotherapy, with
the development of nephrotoxicity, among other toxicity profiles, as well as in cases of weight
gain, patients may receive low doses and compromise the therapeutic response to the tumor.

Objective:

To evaluate weight gain and loss in cancer patients undergoing chemotherapy.

Methods:

Longitudinal analytical study with patients at the end of chemotherapy treatment of both
genders. The type, location of the tumor and the antineoplastic agent used were collected from the
medical records, as well as height and weight at the beginning of treatment. At the time of collection,
anthropometric assessment was performed using body mass index, arm circumference, arm
muscle circumference, triceps skinfold thickness and percentage of weight loss.

Results:

Among the patients included in the study, 47.5% had a weight gain of around 2.5 kg,
while the remaining patients (52.5%) had a weight loss of around 2.8 kg. Of the patients who had
GFR, 55.5% had severe PP, 33.4% had no significant loss and 11.1 had significant loss. In the current
study, only 22% had a GFR <60ml/min/1.73m2, but they would already need to readjust the
medication calculation.

Conclusion:

It is important to evaluate body surface variations and also the GFR to adjust the dose
of the antineoplastic agent and to prevent or minimize nephrotoxicity, as well as to reduce the risk
of underdosing and inefficiency of the therapy.

On the other hand, depression and Internet addiction are factors affecting students' academic performance.

Objective:

This study aimed to investigate Internet addiction, depression and their relation with academic failure in students of Semnan Allied Medical Sciences.

Methods:

In this cross-sectional study, all students who were in the 3rd and higher semesters were examined. Three questionnaires (demographic, Beck Depression Inventory, and the Internet Addiction Test by Young) were used. The academic failure was assessed using the student's grade point average in the previous 3 semesters. Collected data were analyzed through descriptive and inferential statistics methods at the significance level of 0.05.

Results:

170 students participated in this study. The correlation between depression and grade point average changes was found to be negative (r=-0.19) and significant (p=0.01). Moreover, a positive (r=0.39) and significant (p=0.01) correlation was observed between depression and internet addiction scores. Binary logistic regression analysis also indicated that students' depression score (P=0.04, OR1.04, CI 95%=1-1.08) and sex (P=0.008, OR=0.37, CI 95% = 0.17-0.77) can predict academic failure.

Conclusion:

Due to the observation of internet addiction and depression in the students and effects of these disorders on their academic performance, it is necessary to educate students and families, identify risk factors and provide solutions to deal with them.

Published: December 2021

Women's inferiority persists, particularly in patriarchal societies. In Russia, women have always been treated as second-class citize (Placeholder1)ns to men. As a result, because it is a system that already exists in society, women's inferiority is the fundamental problem of inequality for women in Russia. The novel The Kreutzer Sonata explores the inferiority of female characters in nineteenth-century Russia, where the church's influence is still strong. The aims of the research were to examine about women inferiority and struggle in patriarchal society as portrayed in the novel The Kreutzer Sonata by Leo Tolstoy. The data was collected using the following methods: 1) attentively reading the novel to determine which sections featured inferiority and struggle, and 2) collecting notes and marking the facts of inferiority in the marriage and society. 3) categorizing; and 4) analyzing. Based on the research, it was discovered that there were two major forms of women's inferiority: 1) the feeling of powerlessness in decision of marriages. This powerlessness happens to both the mother and the daughters. 2) being subjected to discriminatory treatment, such as a lack of freedom and mobility based only on sexuality, as well as physical abuse and loss of inheritance.

Online Diagnosis-Treatment Department Recommendation based on Machine Learning in China (Preprint)
Authors: Shuangzhu Zhang , Chunhua JU , Meiyu FANG
Published: December 2021

BACKGROUND

As a supplement to the traditional medical service mode, online medical mode provides services of online appointment, online consultation, online remote treatment, etc. Through interactive communications of doctors-patient's Q&As, doctors would have a preliminary diagnosis and then provide patients with services such as telling medical knowledge, making diagnosis, as well as giving diagnosis-treatment advices.Due to the complexity of online medical service application scenarios and the necessity of professional knowledge, the accuracy of the department during patient online consultation is limited, and traditional recommendation methods in the medical field face problems such as low computational efficiency and poor effectiveness Machine learning has been widely and successfully applied in medical fields . Hence, this study applies machine learning technology to intelligent department recommendation for online diagnosis-treatment services, with the purpose of recommending appropriate departments for patients according to the consultation text entered by patients online.

OBJECTIVE

This paper compares the accuracy rate of different machine learning algorithms utilized for intelligent medical department recommendation at online diagnosis-treatment platforms, aiming to extract new features from the research data to improve recommendation effect.

METHODS

Based on 57632 pieces of online diagnosis-treatment data from 20 second-level departments at WeDoctor platform, the accuracy rates of two text vectorization methods in implementing intelligent department recommendation pairing with four classifiers, namely support-vector machine, random forest, multinomial Bayes and logistic regression, were compared from the perspective of hierarchy classification of department and secondary department. Furthermore, the paper also introduces variable of gender and age to improve accuracy rate of department recommendation.

RESULTS

The recommendation accuracy rate is the best when text vectorization method is word2vec and classification algorithm is support-vector machine. The accuracy rate is 79.40% after adding age and gender into the model. The accuracy rate of intelligent recommendation was only about 52.7% for general surgery department and the reason behind is probably that online consultations from patients are usually so complicated that department functions are prone to be confused.

CONCLUSIONS

The effect of machine learning for online diagnosis-treatment platforms’ intelligent department recommendation is particularly significant. And the recommendation accuracy rate can be further improved by integrating age and gender into the algorithm. Moreover, considering the fact that some disease symptoms are confusing and can affect the recommendation accuracy rate to some extent, multiple departments shall be recommended to improve patients' online diagnosis-treatment experience and satisfaction.

Published: December 2021

Munronia is a genus in the Meliaceae family, which consists of over 17 species that are distributed in the subtropical and tropical area of Asia, including southern China, Vietnam, Myanmar, Sri Lanka, India, Indonesia, and the Philippines. It is known that these plants contain valuable bioactive compounds. Since the first isolation of new stigmastane steroid was reported in 2003, researchers have been able to study the chemical composition of these plants, especially the largest secondary metabolite obtained, limonoid. About 97 compounds were isolated successfully and characterized. The reported compounds showed various biological activities, such as antifeedant, antimicrobial, antiangiogenic, cytotoxic against several cancer cell lines, inducing apoptosis, and anti-tobacco mosaic virus activities. Therefore, the results suggest that the use of this plant as a source of bioactive compounds is promising for the medicinal chemistry field.

The study presented in this article focuses on the signification of the poetic metres and the theory of rasa expounded in Candrakiraṇa, a guide to the composition of kakawin that is preserved in the scriptoriums of mountains. The use of the poetic metres and theory of rasa was examined in the text of Sītā’s letter to Rāma that was taken from the Rāmāyaṇa Kakawin. It was carried out on the three manuscripts of Candrakiraṇa preserved by the National Library of Indonesia (PNRI). The findings show that the use of śārdūlawikriḍita metre in Sītā’s letters results in a form of signification for particular aesthetic experiences (rasa), namely karuṇa (sympathy), bhayānaka (concern), śānta (peace) and śṛṅgara (love). Tulisan ini berfokus pada metrum dan teori rasa sebagai sarana pemaknaan yang dimuat dalam Candrakiraṇa, sebuah pedoman penulisan kakawin yang diwariskan di skriptorium-skriptorium pegunungan. Metrum dan teori rasa tersebut dikaji penggunaannya dalam surat Sītā kepada Rāma yang terkandung dalam Kakawin Rāmāyaṇa. Kajian ini melibatkan tiga manuskrip yang merupakan koleksi Perpustakaan Nasional Republik Indonesia. Hasil analisis menunjukkan bahwa metrum śārdūlawikriḍita yang digunakan pada surat Sīta menunjukkan bentuk pemaknaan untuk pengalaman-pengalaman estetika (rasa) tertentu, yaitu karuṇa (belas kasihan), bhayānaka (kekhawatiran), śānta (damai) dan śṛṅgara (cinta).

This study is motivated by several reasons, and one of them is the lack of ecofeminist studies of Indonesian novels. The previous studies focus on novels written by women. Ecofeminist studies of Indonesian novels written by men have not been available so far. The analysis in this study is descriptive with hermeneutic technique of interpretation. This is part of a collective research project in this area. The study leads to a conclusion that Tere Liye’s novel, Si Anak Pemberani, contains some ecofeminist values. The most represented ones in the text are the natural ecofeminist values because there is essential relationship between women and nature. The least represented ones are the spiritualist ecofeminist values because the relationship between spirituality and nature is considered a mystical belief that is no longer relevant in modern society. Penelitian ini dilatarbelakangi oleh beberapa hal; salah satunya adalah belum adanya kajian ekofeminisme terhadap novel-novel Indonesia. Penelitian-penelitian yang sudah pernah dilakukan selalu dilakukan terhadap novel-novel yang ditulis oleh pengarang perempuan sementara penelitian ekofeminisme terhadap novel-novel Indonesia yang ditulis oleh laki-laki belum ada. Berdasarkan hal tersebut, masalah yang dideskripsikan dalam penelitian ini adalah “Bagaimanakah perspektif ekofeminis tercermin dalam novel Si Anak Pemberani karya Tere Liye?”. Teori yang digunakan adalah teori ekofeminisme yang meliputi (1) ekofeminisme alam, (2) ekofeminisme spriritualis, dan (3) ekofeminisme sosialis. Penelitian ini bersifat kualitatif dan merupakan penelitian kepustakaan. Metode analisis yang digunakan adalah metode deskriptif yang didukung oleh teknik hermeneutik. Hasil penelitian menunjukkan bahwa terdapat perspektif ekofeminis dalam novel Si Anak Pemberani karya Tere Liye. Aliran ekofeminisme yang dominan adalah aliran ekofeminisme alam karena pada dasarnya perempuan memiliki kedekatan dengan alam. Aliran yang paling sedikit ditampilkan adalah aliran ekofeminisme spiritualis karena pada zaman sekarang kedekatan secara spiritualis dengan alam dianggap hal mistis yang tidak lagi dipercayai oleh masyarakat.

Indoor culture requires a variety of inputs to get maximum biomass. These inputs are the nutrients, temperature, humidity, and light which plants needed to photosynthesize. Different types of light have been studied and it is known that the same spectrum will give different responses by different plants. The purpose of this study was to find out the effect of red-blue-white light LED on lettuce growth compared to grow light LED as a control which commonly used in plant factory rooms. The red-blue-white light is arranged on a 100 cm long aluminum rod, mounted along the plant in a gully DFT hydroponic fed by 1000-2000 ppm nutrients of ABmix plus with a pH of 5.5-6.5. LED grow light provided the plant a significantly higher height of 16.30% compared to red-blue-white light, but was no different to the length of lettuce root. The number and the area of leaves in red-blue-white light were markedly higher at 16.67% and 33.78% respectively than grow light. In addition, the red-blue-white light increased the chlorophyll content, fresh weight, and dry weight of lettuce plants, by 25.00%, 101.49% and 58.13% consecutively. Therefore, these results suggested that the red-blue-white LED light provided a significant higher biomass than the grow light LED.

Two field experiments were conducted for two cropping seasons at the Multipurpose Crop Nursery of the Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development Mampong-Ashanti, from August to November, 2015and June to September, 2016 to determine the response of cabbage (Brassica oleracea var capitata) to organic and inorganic fertilizers on growth, yield and incidence of insect pest. The experimental design used for the field experiment was a randomized complete block design (RCBD) with three replications. The treatments were: poultry manure (20 t ha-1) + Cypermetrine (30 l ha-1), cow dung (20 t ha-1) + Cypermetrine (30 l ha-1), N.P.K (15:15:15) (300 kg) + Cypermetrine (30 lha-1), foliar + Cypermetrine (30 l ha-1), poultry manure (20 t ha-1) + neem leaf extract, cow dung (20 t ha-1) + neem leaf extract, N.P.K (15:15:15)(300 kg) + neem leaf extract, foliar + neem leaf extract and the control (no fertilizer and no insecticide). The result revealed that the application of organic manure (poultry manure and cow dung) and inorganic fertilization is a better option for soil fertility enhancement in cabbage production.High percentage crop establishment (>95%) was achieved across treatments with NPK + Cypermetrine, poultry manure + neem, N.P.K (15:15:15) + Neem or Foliar fertilizer + neem achieving 100% crop establishment. The application of Cow dung+ NLE produced the highest number of open leaves in both seasons. Application of poultry manure and N.P.K combined with Cypermetrine significantly improved head weight and cabbage yield.Application of poultry manure combined with Cypermetrine or neem leaf extract produced earliest head initiation and widest head diameter.In conclusion cabbage growers are encouraged to use poultry manure at 20 t ha-1 and N.P.K (15:15:15) (300 kg) combined with Cypermetrine at 30 l ha -1 and neem leaf extract for the improvement of cabbage growth, yield and incidence of insect pest.
Object Tracking Using HSV Values and OpenCV
Authors: Shafi Gowher
Published: December 2021

Abstract: This research shows how to use colour and movement to automate the process of recognising and tracking things. Video tracking is a technique for detecting a moving object over a long distance using a camera. The main purpose of video tracking is to connect target objects in subsequent video frames. The connection may be particularly troublesome when things move faster than the frame rate. Using HSV colour space values and OpenCV in different video frames, this study proposes a way to track moving objects in real-time. We begin by calculating the HSV value of an item to be monitored, and then we track the object throughout the testing step. The items were shown to be tracked with 90 percent accuracy. Keywords: HSV, OpenCV, Object tracking, Video frames, GUI

Abstract: Optical fiber is a medium that made by silica or plastic, and widely used in transmitting information over longer distance especially in communication system. There are three types of fiber optic used in this project which are single mode stepindex (SMSI), multimode step-index (MMSI), and multimode graded-index (MMGI) in optical communication system. There are three objectives in this project in order to get the suitable optical fibers in the communication system. First objective is to simulate the result by using Excel and Origin software. The data and the formula of fiber optics will be key in through Excel software while the graph will be analyzed by using Origin software. The second objective is to compare the different types of fiber optics in communication system by comparing the several of their characteristics such as numerical aperture (NA), acceptance angle (θ(a)) and propagation constant (β). The performance of all types fiber optics are analyzed from the result using the standard communication wavelength of 1550 nm. The core diameter for SMSI, MMSI, and MMGI are 9, 200 and 50 μm respectively while the cladding diameter for SMSI and MMGI is 125 μm and 240 μm for MMSI. This diameter also been analyzed by using the standard value for optical communication system. Then, the comparison between SMSI, MMSI and MMGI will be made to choose the more suitable for optical communication system based on their characteristics. From the results, MMSI and MMGI give best performance compared to SMSI. After that, the third objective is to make the comparison between MMSI and MMGI in term of intermodal dispersion to compare the efficiencies of fiber optics. MMGI give the better result in terms of efficiencies for communication system compared to MMSI.
