Carotid Artery Blood Flow Changes Associated with Head Positioning in Patients Undergoing Thyroidectomy
Authors: Asokan Abhilash , Sreejit Melveetil S.
Published: August 2022

Background and Aims:

There are possibilities of insufficiency in blood flow through carotid arteries during head positioning in thyroid surgeries under general anesthesia which is usually compensated by collateral circulation in normal conditions. This compensation may be hampered in patients with congenital abnormalities or diseases such as atherosclerosis. We aimed to elucidate the changes in common carotid artery blood flow related to head positioning during thyroid surgery by Doppler examination.

Methods:

In this observational prospective study, Doppler examination of both common carotid arteries including arterial diameter, peak systolic velocity, average velocity, and blood flow volume of forty patients who had undergone elective thyroidectomy under endotracheal anesthesia was done. Three sets of data (baseline, after induction, and after surgery) were collected and analyzed.

Results:

There was a significant reduction in the diameter (P = 0.002) and the blood flow (P = 0.0001) in both carotid arteries and an increase in peak and mean velocity which was more pronounced immediately after head positioning and persisted till the end of the procedure. There was no correlation between the hemodynamic parameters with the carotid artery diameter, blood flow, and velocity.

Conclusions:

The head-and-neck positioning during thyroidectomy surgery reduces the blood flow through the carotid arteries which continued till the end of the procedure.
Levobupivacaine versus Levobupivacaine Plus Dexmedetomidine in Transversus Abdominis Plane Block in Patients Undergoing Abdominal Aortic Surgery
Authors: Abdallah Maha Younis Youssef , Abdallah Mohamed Younes Yousef
Published: August 2022

Background:

Severe postoperative pain is a major dilemma for patients undergoing abdominal aortic surgery. Transversus abdominis plane (TAP) block has been described a successful pain management technique after major abdominal surgery. Dexmedetomidine was proved to enhance the analgesic action of local anesthetics.

Aim:

This study was aimed to assess the impact of adding dexmedetomidine to levobupivacaine during TAP block in patients undergoing abdominal aortic operations.

Patients and Methods:

We included 114 patients in this prospective trial, and they were enrolled into two groups; the L group received levobupivacaine only, and the LD group received levobupivacaine plus dexmedetomidine. The block was performed before anesthetic induction. Postoperative pain score was our main outcome.

Statistical Analysis:

The collected data were tabulated and analyzed through the SPSS software program IBM's Statistical Package for the Social Sciences (SPSS) statistics for Windows (version 25, 2017) (IBM Corporation, Armonk, NY, USA). The categorical data were expressed as numbers and percentages and then compared using the Chi-square test. The continuous data were expressed as mean and standard deviation if normally distributed, or median and range if abnormally distributed. The former data were compared through the one-way ANOVA, while the latter were compared through the Kruskal–Wallis test. Any P < 0.05 was considered statistically significant.

Results:

Group LD showed significantly earlier sensory blocks compared to the other group. Postoperative pain scores were comparable between the two groups for the initial 4 h following the surgery. Adjuvant dexmedetomidine was associated with better pain scores for the subsequent 12 h compared to Group L. The duration till the first analgesic request showed a significant increase in the LD group (13.3 vs. 11.09 h in Group L). In addition, the same group showed a significant decline in their opioid consumption after the operation (48.95 μg vs. 72.63 μg in the other group). Postoperative nausea and vomiting were significantly increased in Group L.

Conclusion:

Adjuvant dexmedetomidine has a significant beneficial impact on postoperative analgesic profile. Its use as an adjuvant to peripheral and neuraxial nerve blocks should be recommended in pain management practice.
Enamel Surface Roughness Evaluation After Bracket Debonding
Authors: Chandrasekharan Deepak , Sourabh Chandan , Deenadayalan  , Praveen Katepogu
Published: August 2022

Introduction:

After fixed orthodontic treatment, following bracket removal, the debonding procedure should lead to restitutio ad integrum of the enamel or, at least, restore the enamel surface as closely as possible to its pretreatment condition. Adhesion of brackets in orthodontics is that they should be strong enough to prevent failure during all treatment but also low enough, so that enamel damage would be minimal during bracket removal after treatment.

Material and Methods:

A total of 60 premolars were collected and stored in distilled water. The extracted teeth were divided into two groups of 30 each, group A was to be bonded with self-cure adhesive while group B light cure adhesive was to be used. A standardised protocol was followed for adhering the brackets to the tooth surfaces. All the teeth were bonded with metal brackets (3M Unitek, Gemini Twin Brackets 0.022 slot). In group A, bonding adhesive (3M Unitek self cure adhesive primer) was applied. In group B, the bonding adhesive (3M Unitek light cure adhesive primer) was photopolymerized for 10 seconds after application.

Results:

Surface roughness of enamel as assessed by profilometry shows that light cure adhesive creates more roughness as compared to self cure adhesive. To conclude, self cure adhesive is clinically better than light cure adhesive.

Discussion:

In the present study enamel surface roughness were compared after debonding. Enamel surface roughness after bracket debonding depends on a host of factors, which include – brackets, adhesive used and method of remnant removal.

Authors: Dhillon Jatinder K. , Ghosh Sujoy , Mathur Vijay P.
Published: August 2022

Objectives:

To evaluate the root and canal morphology of primary maxillary and mandibular molars in an Indian population using cone-beam computed tomography (CBCT).

Methods:

A retrospective cross-sectional study was performed, where CBCT scans of children less than 10 years of age taken for valid diagnostic purposes previously were considered and images were analyzed. The number of roots, root canals, and variations in morphology were recorded. Left–right symmetry was also noted.

Results:

A total of 433 deciduous maxillary and mandibular primary molars were studied. It was observed that two separate roots with three separate canals were common in primary mandibular first molars, whereas two separate roots with two canals in each root were common in mandibular second primary molars. In primary maxillary molars, three separate roots with one canal each were the most common. Maxillary first molars (17.21%) and 17.35% second molars had fused distobuccal and palatal roots. It was observed that primary maxillary molars showed more left–right symmetry (86.7% in first molars and 82.7% in second molars) compared to primary mandibular molars (54.05% in first molars and 68% in second molars).

Conclusions:

It was concluded that in both primary maxillary first and second molars, three separate roots, a mesiobuccal root, a distobuccal root, and a palatal root with one canal in each root, were the most common. Two separate roots with three separate canals were the most common in primary mandibular first molars, whereas two separate roots with two canals each in both roots were more common in mandibular second primary molars.

Authors: Gautam Anju , Mittal Neelam , Mishra Surendra Pratap , Singh Tej Bali , Chandra Akhilesh
Published: August 2022

Background:

Reactive oxygen species released on stimulation by periodontal pathogens cause oxidation of biomolecules and play significant role in periodontal disease pathogenesis.

Aim:

This study aimed to evaluate the levels of oxidative by-products malondialdehyde (MDA) and 8-hydroxy deoxyguanosine (8-OHdG) as biomarkers in chronic periodontitis patients compared to healthy as well as before and after nonsurgical periodontal therapy. The correlation between biomarkers and clinical attachment level was also evaluated.

Settings and Design:

A total of 112 subjects were included in this study. The subjects were divided into two groups (Group I included 56 healthy subjects and Group II constituted 56 chronic periodontitis patients) on the basis of clinical periodontal parameters.

Materials and Methods:

Group I subjects received no treatment and were evaluated once only for clinical and oxidative stress biomarker parameters. Nonsurgical periodontal therapy was carried out in Group II patients and they were evaluated at baseline and 3 months after therapy.

Results:

Both salivary and serum levels of MDA and 8-OHdG were found to be increased in chronic periodontitis patients as compared to healthy subjects. After nonsurgical periodontal therapy, the levels of MDA and 8-OHdG significantly reduced. Linear correlation between clinical attachment level and oxidative stress parameters was found to be positive and highly significant.

Conclusion:

It can be concluded that periodontal therapy is effective in improving the oxidative stress condition.

POTENTIAL USE OF BIOCHAR IN WASTEWATER TREATMENT OPERATIONS AND SOIL IMPROVEMENT
Authors: Gokalp Zeki , Bulut Sancar
Published: August 2022

Biochar is produced through thermochemical decomposition, so called as pyrolysis, of different biomass groups in the presence of little or no oxygen. Resultant material is highly stable material with excellent surface characteristics and pore structure and is also rich in functional groups. Such properties of the material are largely influenced by pre- and post-treatments and thermal decomposition conditions. Various methods have been used for thermal decomposition of biomass, such as pyrolysis thermal carbonization, torrefaction and microwave heating at different temperatures and for different durations. Biochar has recently started to be used for wastewater treatment and water pollution control purposes. It is also used to improve soil properties including aggregate stability, water holding capacity and organic matter content. It is a new, economic and environment friendly material to be used in wastewater treatments technology and soil improvement. In this study, biochar production technologies and properties of resultant materials were summarized and potential use of biochar in wastewater treatments operations and for soil improvement were assessed in detail.

Published: August 2022

The floristic diversity analysis made it possible to distinguish 42 species listed in 30 genera and 17 families in the Sfissifa station and 34 species classified in 23 genera and 15 botanical families in the El Biodh station. The most representative families in the Sifissifa station are: Asteraceae (14,28 %), Amaranthaceae (11,90 %), Brassicaceae (11,90 %), Poaceae (7,14 %), Lamiaceae (7,14 %) and Cistaceae (7,14 %). The dominant families in El Biodh station are Asteraceae (17,64 %), Poaceae (11,74 %), Amaranthaceae (8,82 %), Brassicaceae (8,82 %), Lamiaceae (8,82 %) and Cistaceae (8,82 %). The other remaining families have only one or two species with estimated rates ranging from 2,38 % to 4,76% in Sfissifa and 2,94 % to 5,88 % in El Biodh. The study of biological types shows the abundance of therophytes in the two stations with 42.86 % at Sfissifa and 50 % at El Biodh, which reflects the importance of the anthropologic action and the xericity of the climate. The analysis of the biogeographical spectrum shows the dominance of native species of the Mediterranean (19 species in Sfissifa and 15 species in El Biodh). The AHC analysis of the data revealed the main factors controlling the distribution of plant formations in the two studied stations including overgrazing, salinity and desertification. The combination of prolonged droughts and anthropogenic pressures exerted on the studied areas results in the extension of species of low pastoral value and the appearance of vast expanses of bare soil reaching the stage of desertification.

Authors: Gün Büşra , Yilmaz Semih
Published: August 2022

Enzymes with very important duties, form part of our lives and are useful in various fields. Owing to both the intensity of use and the amount of effective production in standard conditions, the production and use of bacterial-originated enzymes are used continuously in agriculture, health, food and many other industrial areas. Among them, transglutaminases (EC 2.3.2.13) are both intracellular and extracellular enzymes included in the transferase group that catalyse cross-links between proteins. Microbial transglutaminase enzymes are frequently used in the food and pharmaceutical industries to change the functional properties of proteins since it increases viscosity, elasticity and water holding capacity. Particularly the positive effects in meat, dairy, and bakery products such as gelling, increasing mechanical strength, and reducing structural deformations, specifically the texture. It also contributes to reducing the use of additives in diets with low protein and fat content. Furthermore, it reduces the time for cooking processes as well as sensory properties enhancement. Transglutaminase enzymes are also being used in other fields such as tissue culture, biochemical and biomedical research, textile, and leather industries. In this review, a broad perspective is presented on the literature dealing with bacterial transglutaminase studies, especially those belonging to the genus Bacillus. In Bacillus spp., transglutaminase gene was mostly reported in B. subtilis, B. amyloliquefaciens, B. cereus, B. nakamura, B. circulans species and also recently in the whole genome of local Bacillus thuringiensis (Bt) SY49.1 strain (JAHKEZ010000474.1) using the RAST database. It was determined that the Bt transglutaminase gene was 93% identical to that of B. cereus species. The presence of transglutaminase gene in agriculturally indispensable Bt strain can confer them a superficial characteristic due to their water holding capacity in terms of increasing the yield and quality of plant products.

The study was conducted to determine the struggles of senior citizen teachers during the S.Y. 2021 - 2022. The descriptive qualitative method as research design was used and an in-depth interview was utilized in data collection. The study reveals that majority of the respondents have no choice but to keep up with the use of technology in their teaching so that they will not be left behind. It this time of digital world we are now living in, it is important to use and integrate technology in teaching to catch the attention of the learners who are now called digitally natives. Research shows that integrating technology in the teaching-learning process will benefit learners and they will easily understand their lesson with the use of video lessons. The more senses they use, the better the comprehension and retention of their lessons. It will also lessen the time and effort of teachers in making instructional materials and it will make the discussion livelier. There are also advantages and disadvantages of the utilization of technology inside the classroom. It has also its limits. Some identified struggles of senior citizen teachers were namely; lack of available gadgets, poor internet connection, sudden power interruption and lack of basic knowledge of the older teachers in the operation of such modern gadgets. But luckily enough, they have their supportive co-teachers and family members around them who are willing to assist them.

Published: August 2022

Learning resources are the most urgent thing in the learning process, including history learning. However, until now there have been no learning resources in the form of books or other media made based on the characteristics of history itself, namely Historical Thinking. Historical thinking is only discussed as part of historical scholarship. In fact that is the main purpose why history should be taught. In essence, by studying history, students understand chronology, have the ability to analyze causality, causal relationships of each event, are able to interpret events correctly, think three dimension of time, and are able to take values from events that can be applied in today's life. Based on this, this study aims to produce learning resources in the form of video media designed based on Historical Thinking. Where historical material is not focused on describing facts, but analyzing facts and inviting students to practice historical thinking.

Educação Ambiental na Educação Profissional: uma análise dos Planos de Curso dos cursos técnicos do Senai Araguaína – TO
Authors: FURTADO WESLEI RIBEIRO , SOARES SARA JOSÉ , DOS SANTOS VANGELA AZEVEDO
Published: August 2022

Analisar a Educação Ambiental, principalmente nos espaços escolares, é garantir o entendimento da sua essência e da sua importância para a sociedade, tendo em vista a preservação e a conservação dos recursos naturais, objetivando a construção de uma mentalidade que prime pela sustentabilidade e que pela qual o sujeito se veja responsável pelas causas ambientais. Nesse sentido, a Educação Ambiental se torna um meio imprescindível para isso, pois aliá-la à Educação Profissional se faz necessário, a fim de formar pessoas críticas e preocupadas com o meio ambiente em que vivem e de romper com fatores históricos que ligam a educação técnica apenas à formação de mão de obra. Logo, o presente artigo aborda a realização de uma pesquisa documental do tipo exploratória que busca identificar como é tratada a temática da Educação Ambiental nos Planos de Curso dos cursos técnicos ofertados pelo Serviço Nacional de Aprendizagem Industrial (Senai) no Departamento Regional do Tocantins, na cidade de Araguaína – TO, especificamente nas unidades de ensino. Como resultado, pode-se constatar que, dos nove cursos em andamento na cidade, apenas quatro tinham unidade específica sobre a temática, e os outros tratavam o tema de forma interdisciplinar. Assim, compreende-se que a Educação Profissional vem, aos poucos, superando o pensamento assistencialista que outrora assumia para as classes populares e se transformando em perspectiva humanista que forma educandos com senso crítico e competências para a vida e para o trabalho, sempre buscando um desenvolvimento integral e humano, não podendo tal fato ser dissociado das práticas ambientais responsáveis.
Avaliação do desempenho físico entre blocos de adobe com adição de pó de pedra comparados com adições de esterco e serragem
Authors: Franco Fernanda Miguel , Valin Jr, Marcos De Oliveira , Ribeiro Karyn Ferreira Antunes
Published: August 2022

As construções em adobe são realizadas em várias partes do mundo. No entanto, essa tradição construtiva, originada das tradições portuguesas, caiu em desuso no Brasil. Dessa forma, o conhecimento e aprimoramento de técnicas para a confecção e uso do adobe se torna uma solução para alguns dos problemas atuais da construção civil, principalmente por ser um material de baixo impacto ambiental. O objetivo do trabalho foi avaliar as propriedades físico-mecânicas de adobes produzidos com solo do Pantanal Mato-Grossense, com incorporação de outros materiais, sendo uma mistura de solo: esterco: serragem: água (traço em volume de 6: 1: 1: 0,9) e outra de solo: pó de brita: água (traço em volume de 6 :1: 0,9), identificando as influências causadas pelas incorporações. O estudo sobre técnicas de construção vernaculares começou como exercício pedagógico da disciplina de Construções Rurais, no IFMT. A forma de produção e preparação da massa do adobe teve como referência trabalhos de Ferreira et al. (2012), Amaral (2017), Vendramini et al. (2018), entre outros. Os ensaios foram balizados pelas NBR 10836 (ABNT, 2013), NBR 16814 (ABNT, 2020) e NBR 9779 (ABNT, 2012). Concluímos que os tijolos de adobe fabricados e testados com incorporação de pó de brita atenderam às especificações normativas de resistência à compressão, enquanto os tijolos produzidos com esterco e serragem não atingiram o valor de referência. Quanto aos resultados da absorção de água por capilaridade, os valores dos testes demostraram que o material é vulnerável à água e não resiste à saturação por 48 horas consecutivas.

Published: August 2022

Este estudo objetiva, a partir de uma revisão narrativa da literatura (RNL), evidenciar por meio de produções científicas publicadas entre os anos 2006 e 2021, os principais impactos psicológicos ocasionados pelo fim de um relacionamento amoroso em indivíduos do sexo feminino. Para a construção dessa revisão, realizou-se uma busca nas bases de dados Scielo, Pepsic, Pubmed/Medline, BVS/Lilacs e Google Acadêmico, nos meses de junho e julho de 2021. O encaminhamento de seleção foi dividido em duas etapas: na primeira, foi feita a busca inicial, sendo encontrados 157 artigos; na segunda etapa, foi realizada a leitura, considerando os critérios de exclusão e inclusão. Por fim, foram selecionados 13 artigos para amostra final deste estudo. A partir dessa amostra, os resultados encontrados evidenciaram a presença de efeitos negativos como depressão, angústia, estresse, tristeza e luto, assim como efeitos positivos como o alívio e a felicidade foram também encontrados, sendo os efeitos negativos aqueles com maior frequência. Para além disso, os resultados do estudo também constataram que as mulheres podem ser, frequentemente, vítimas de perseguição ou stalking, ameaças e violência, ressaltando também que esta população seria a que mais sofre com brigas na ocorrência de um rompimento. Enfim, concluiu-se que o término de um relacionamento amoroso pode vir a ocasionar implicações psicológicas desde sofrimento psíquico e traumas até o desenvolvimento de transtornos psiquiátricos na população feminina. Acreditamos que isso se dá, possivelmente, devido à socialização feminina voltada para os relacionamentos amorosos como caminho para o sucesso e através da produção de sentido da vida por meio da constituição familiar.

Published: August 2022

O presente trabalho teve como objetivo realizar o diagnóstico ambiental dos corpos d’água que cortam a área urbana do município de Paraíso do Tocantins, identificando as principais causas da degradação da qualidade ambiental e suas consequências para a qualidade da água. Para tanto, inicialmente, foi realizado um diagnóstico ambiental dos principais cursos d’água existentes na cidade (córregos Pernada e Buriti), por meio de visitas a campo. Posteriormente, foram selecionados pontos para o monitoramento da qualidade da água ao longo de cada canal de drenagem, sendo: ponto 1 – a montante da área urbana; ponto 2 – no início da área urbana; ponto 3 – no meio da área urbana; e ponto 4 – a jusante da área urbana, para os quais foram realizadas análises físicas, químicas e microbiológicas, conforme Standard Methods for the Examination of Water and Wasterwater. Os resultados indicaram alterações significativas sobre a qualidade da água ao longo dos corpos d’água avaliados, sendo verificados padrões de qualidade da água em desacordo com a legislação para os parâmetros nitrito, fósforo total, oxigênio dissolvido e coliformes termotolerantes. Desse modo, a realização deste trabalho permitiu uma análise mais abrangente dos efeitos do uso e da ocupação do solo sobre a qualidade ambiental dos corpos d’água urbanos do município, sendo bastante útil para fomentar as discussões e o planejamento de políticas municipais voltadas à gestão do uso do solo urbano.

Published: August 2022

Uma gestão escolar que permite a adequada aprendizagem do aluno e a analisa com diversos fatores do contexto escolar, como índices assiduidade e ocorrências disciplinares, por exemplo, torna-se importante para uma melhor adequação do projeto pedagógico da instituição e para o sucesso da evolução do aluno em meio acadêmico e na sociedade. Com base nessa afirmação, o presente trabalho teve como objetivo analisar as relações entre o aproveitamento, assiduidade e ocorrências disciplinares dos alunos egressos do curso integrado em Técnico em Agropecuária do IFC, Campus Camboriú, com os aspectos relacionados à permanência do aluno em sala de aula. De cunho quantitativo e de análise documental institucional, os resultados apresentaram relação estatisticamente significativa entre rendimento escolar e frequência (assiduidade). Não houve diferença significativa entre rendimento escolar e ocorrências disciplinares. Concluindo, pode-se afirmar que identificar os aspectos relacionados a permanência do aluno em sala de aula e rendimento escolar são ferramentas de suma importância na reflexão das ações correspondentes na gestão escolar. Como trabalhos futuros, sugere-se a definição e implementação de estratégias que, tendo por base o conhecimento adquirido neste estudo, promovam a melhoria do sucesso escolar no Instituto Federal Catarinense Campus Camboriú não só no curso técnico, como também em nível de graduação. A realidade para cada curso não é necessariamente igual e poderá necessitar de estratégias diferentes para aumentar o sucesso escolar. Por outro lado, outras variáveis explicativas poderão ser consideradas em futuros estudos.

A metodologia ABNT NBR 15575:2013 para avaliação do desempenho térmico sofreu diversas críticas ao longo dos anos. Por este motivo, um novo texto foi proposto, avaliado e aprovado em consulta pública em janeiro de 2021 e já está publicado. Sendo assim, o estudo em questão buscou compreender as duas metodologias (2013 e 2021) de forma comparativa a fim de entender suas diferenças, verificar se houve evolução e analisar sua restrição em relação ao mercado da construção civil e ao desempenho das unidades habitacionais. Constatou-se que a nova metodologia é menos permissiva em relação aos níveis de desempenho térmico Intermediário e Superior, mas, por outro lado, apresenta certa facilidade na obtenção do desempenho Mínimo. Além disso, resulta em melhor nível de desempenho para climas onde a necessidade do condicionamento artificial é menor. O nível de complexidade da nova metodologia é maior sendo este um possível indicativo do aumento de valor e tempo dos serviços prestados para comprovação do desempenho.

Este estudo apresenta uma proposição de benchmarking estatístico do estoque de edificações escolares no Brasil. Informações de consumo de energia, área construída, número de alunos e localização (zona bioclimática) de 2.445 escolas foram utilizadas para se calcular indicadores de intensidade de uso de energia (EUI) em termos de área construída e número de alunos, realizando-se também uma transformação logarítmica para garantir aderência à distribuição normal. Esses indicadores foram analisados por meio de teste de normalidade, desenvolvimento de histogramas, cálculo de medidas de síntese estatística, e determinação de um benchmarking estatístico por meio de normalização simples. Além disso, uma análise de variância (ANOVA) foi aplicada para verificar se o EUI apresenta variação estatística em relação às diferentes zonas bioclimáticas observadas. Resultados apresentam valores típicos de EUI por área construída e por número de alunos para o estoque de edificações e o benchmarking estatístico apresenta valores limites para classificação do desempenho operacional dessas edificações de “A” (melhor desempenho) até “E” (pior desempenho). O teste estatístico ANOVA apontou que há variação dos valores médios dos EUIs para diferentes zonas bioclimáticas. Conclusões apontam que o método utilizado para benchmarking é válido para uma abordagem primária, porém é limitado por não considerar como parâmetro a localidade da edificação, identificado como importante no teste estatístico empregado. Dessa forma, evidencia-se a necessidade de um método mais robusto para representar o benchmarking energético de edificações no Brasil.

Ergonomia é o estudo das ações e influências mútuas entre o ser humano e o espaço por meio de interfaces recíprocas. Sua principal contribuição no ambiente construído é propor relações e condições de ação e mobilidade, definir proporções e estabelecer dimensões em condições específicas em ambientes naturais e construídos, englobando questões como conforto ambiental e desenho universal. A ergonomia pressupõe a percepção individual e subjetiva de qualidades, influenciada por valores culturais, sociais e cognitivos de comodidade, adequação, expressividade e prazer. Este trabalho teve como objetivo discutir como questões sensoriais são importantes quando se desenham ambientes que devam atender às necessidades de um público que apresenta transtorno de processamento sensorial e cognitivo, como – por exemplo – pessoas com Transtorno do Espectro do Autismo (TEA). Para alcançar este objetivo, foi realizada uma revisão bibliográfica sobre assuntos correlatos e uma análise estruturada da organização dos espaços e atividades de cinco residências assistidas para autistas. Os resultados mostraram uma preocupação em organizar os cômodos de forma que seja fácil de identificar visualmente as atividades e os fluxos esperados em cada espaço, além de estabelecer uma clara divisão entre os ambientes de convívio social e com maiores fontes de estímulos sensoriais e os ambientes privados e com maior controle individual de estímulos.

Catharanthus roseus or “Kemunting Cina” and Clitoria ternatea or “Bunga Telang" had a long reputation as a traditional remedy in South East Asia. One of the important components that contribute to these plants' remedial capabilities is the secondary metabolic known as phenolic. In this study, the Total Phenolic Contents or TPC in Catharanthus roseus and Clitoria ternatea leaves extract have been obtained and compared. Leaves from both species were dried and the extract was acquired using 90% ethanol via a rotary evaporator. Two major tests were conducted which are the qualitative test and quantitative test. The qualitative test was done to ensure the existence of phenolic in the samples. Meanwhile, the quantitative test is to measure the concentration of phenolic in the samples. Both samples show a positive result in a qualitative test where the extract of the sample changed from green to dark green in the Ferric Chloride test. Next, Folin- Ciocalteu assay acted as the quantitative test to determine the TPC in the samples, and the absorbance was measured at 760 nm. The test was triplicated to ensure the consistency of the results. The total phenolic content for Catharanthus roseus is 36.33600 ± 0.935313mg/GAE and Clitoria ternatea is 7.35767 ± 0.046188mg/GAE. The TPC in Catharanthus roseus is higher than Clitoria ternatea. The t-test shows that there is a significant difference in concentration of total phenolic content between Catharanthus roseus and Clitoria ternatea (p

Fermented fruit juice is the material use to increase the soil microbial activity as it made up from fermented fruit in the container for a several time before it became a liquid compose fertilizer. It contains a lot of substances such as an organic compound which is one of the important nutrient source for bacteria in soil. By applying the fermented fruit juice (FFJ) in soil, it will help to increase the soil fertility itself. The aim of the present study is investigate the targeted soil bacteria which is phosphate-solubilizing bacteria inside the soil paddy root. This study was also revealed type of fruit that been used for fermented fruit juice namely corn cobs, coconut, and fruit waste. The statistical analysis has been conducted by using IBM SPSS version 2.0 for the bacteria population calculation. The findings of the present study showed there is significant different between the bacteria population among the treatments and fermented fruit juice can be used as carrier for phosphate solubilizing bacteria and one of the effective biofertilizer to increase soil fertility.

Dragon fruit belongs to the genus Hylocereus of the Cactaceae family. There are two species that are commonly cultivated; Hylocerues polyrhizus and Hylocereus undatus that have the same red skin but different flesh colours, red and white respectively. Although from the same genus, the phytochemical contents and bioactivities of both fruits may not be the same. This study aims to compare the phytochemical contents, antioxidant and antibacterial activities of H. polyrhizus and H. undatus to help consumers better choose nutritional fruits and to explore potential natural preservatives. The fruit samples were extracted using 50% ethanol and later were subjected to phytochemical, antioxidant and antibacterial assays. The phytochemical contents were determined using Folin Ciolcalteu and aluminium chloride methods for total phenolic and total flavonoid respectively. The antioxidant activity was determined using diphenyl-picryl hydrazine (DPPH) and 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. Disk diffusion method was performed to evaluate antibacterial activities against two food-borne pathogens, Escherichia coli and Staphylococcus aureus. H. polyrhizus showed to contain significantly higher phenolic content (p<0.05), while H. undatus had significantly higher flavonoid content (p<0.05). Comparison of antioxidant activities in both fruit samples indicated higher activities were observed in H. polyrhizus and both fruit extracts showed inhibition zones against the tested bacteria with H. polyrhizus extract was able to inhibit at lower concentration. The results suggest that H. polyrhizus may have higher bioactivities compared to H. undatus due to the significantly higher phenolic content.

Vertical Electrical Sounding (VES), Pumping test, well logging and grain size analysis were conducted with the aim of studying the subsurface geophysical formation in order to determine aquifer characteristics such as hydraulic conductivity, transmissivity and other parameters for groundwater exploration purposes around Ogbeje and Umeghe, Abraka Delta State. Nine (9) VES stations were occupied and the results obtained from the computer iterations suggest 4 to 5 geoelectric layers. The aquiferous layers wwerefound at a depth ranging from 20.0 m – 38.3 m with resistivity ranging from 2200 ?m to 8500 ?m and thickness varying between 6.7 and 20.0 m. The VES study reveals the possibility of having a maximum drill depth the o water table of about 38 m. The results obtained from the pumping test and well logginwereas used to estimate the transmissivity value of T = 0.0722 m2/min, storativity S = 0.00063, specific capacity of the well = 0.39 m2/min and hydraulic conductivity, K= 8.5 m/day while the result from the grain size analysis gave hydraulic conductivity as Kmin= 12.96 m/d to Kmax = 26.96 m/d respectively. Thus, these results indicate that the aquifer is capable of proda ucing sufficient amount of water for both domestic and industrial purposes for the people in the area.

In the beverages industry, the stabilizer and emulsifier were used to enhance the quality of Pink Guava Juice Drink (PGJD) in terms of colour, taste, and texture. Thus, the product is favourable and marketable. This study was conducted to find the best emulsifier combination for PGJD. The combination of six different stabilizers such as Guar gum (GG), Carboxyl methyl cellulose (CMC), Arabic gum (AG), Xanthan gum (XG), Propylene glycol alginate (PGA), and Pectin were applied to PGJD formulation. Meanwhile, about three emulsifiers which are Arabic gum (AG), Polysorbate 80 (P80), and Propylene glycol alginate (PGA) were used to emulsify vitamin E in PGJD. The ratio for both stabilizers and emulsifiers varied accordingly. The most stable and suitable combination of stabilizers and emulsifiers was later added to PGJD. The combination of XG and CMC at the concentration of 70:30 with 0.2% (w/v) was the best stabilizer. Meanwhile, P80 was found to be the best emulsifier at a concentration of 0.8% (w/v) and PGJD fortified with 225 mg of vitamin E was chosen as the most acceptable PGJ among panelists. This finding of the present study can be a guideline for beverage manufacturers in selecting the best stabilizers and emulsifiers.
