Published: October 2023

Статья посвящена поиску путей выявления личностных детерминант профессионального утомления субъектов труда в сфере управленческого труда: транспортно-логистических компаний, в которых трудятся менеджеры по продажам услуг. У таких сотрудников выявляется выгорание, профессиональное утомление, стресс, поскольку они обязаны взаимодействовать с человеческими ресурсами, что вызывает у сотрудников эмоциональное истощение, перевозбуждение, конфликтные ситуации. Данная ситуация обусловливает задачи психокоррекционного воздействия и проведения восстанавливающего психологического воздействия. Профессиональное утомление на сегодня очень актуальная проблема, она всегда вызывала интерес у реабилитологов, психологов, потому что, эта проблема могла коснуться каждого. Больше всего склонны к нему люди, работающие в сфере социальных и коммуникативных профессий (медицинские работники, педагоги, социальные работники, психологи, юристы, полицейские и др.). у человека возникает внутри некая опустошенность, из-за постоянного контакта с другими людьми, которые испытывают негативные эмоций и «выбрасывают» на окружающих людей. Одно время такое состояние приравнивалось к эмоциональному выгоранию, впрочем, не имея общего, поскольку относится к сфере труда. Очень низкий уровень эмоциональной реакции был выявлен у 8% (4 человека) сотрудников транспортно-логистической компании.

The article is devoted to the search for ways to identify personal determinants of professional fatigue of subjects of labor in the field of managerial work: transport and logistics companies that employ service sales managers. Burnout, professional fatigue, stress are revealed in such employees, since they are obliged to interact with human resources, which causes emotional exhaustion, overexcitation, and conflict situations in employees. This situation determines the tasks of psycho-corrective influence and carrying out a restoring psychological influence. Occupational fatigue is a very urgent problem today, it has always aroused interest among rehabilitation specialists, psychologists, because this problem could affect everyone. Most of all, people working in the field of social and communicative professions (medical workers, teachers, social workers, psychologists, lawyers, policemen, etc.) are inclined to it. a person has a certain emptiness inside, due to constant contact with other people who experience negative emotions and “throw out” on people around them. At one time, such a state was equated with emotional burnout, however, having nothing in common, since it relates to the sphere of work. A very low level of emotional reaction was found in 8% (4 people) of the employees of the transport and logistics company.

Manaus é uma cidade entrecortada por diversos corpos de água chamados igarapés (caminho de canoa). Esses corpos de água antes preservados, se encontram hoje sob forte pressão poluidora. Um exemplo disso é o igarapé Matrinxã, situado na bacia hidrográfica do Acará, em Manaus, na área de influência do aterro sanitário da capital do Amazonas. Além deste, vários igarapés já foram estudados no município de Manaus em condições naturais, com baixa influência antrópica, como o igarapé da reserva Sauim Castanheiras, o Barro Branco, a nascente do IFAM zona leste e o igarapé Açu. O objetivo deste estudo foi avaliar a qualidade da água de áreas de floresta primária, com áreas circunvizinhas do aterro de Manaus e verificar possíveis ações de diluição/concentração ao longo do percurso desses corpos de água, sobretudo, do igarapé Matrinxxã. Foram realizadas coletas quinzenais e analisadas variáveis ambientais nos períodos de 201-2015 e 2021-2022. Os resultados obtidos naturais foram comparados com os locais manejados em área urbana, e revelaram que nesses ambientes a qualidades das águas são similares, indicando que é possível o seu restabelecimento. No entanto, os corpos de água localizados próximos ao aterro sanitário apresentaram uma forte alteração ocasionada pela mudança nos valores naturais de pH e condutividade elétrica, com altas taxas de compostos nitrogenados, como nitrato e amônio, que se mostraram limitadores do íon silicato, além de baixos teores de oxigênio dissolvido, comprometendo a cadeia trófica deste igarapé, principalmente no denominado igarapé Matrinxã.

Published: October 2023

O objetivo desse estudo é identificar as produções científicas que abordam sobre a implementação e efetividade das políticas públicas e programas de saneamento rural. Para isso, foi elaborado uma revisão sistemática baseada na recomendação de Principais Itens para Relatar Revisões Sistemáticas e Meta-análises (PRISMA). Para a busca, foram utilizadas as seguintes bases de dados e portais acadêmicos: Google Acadêmico; Periódico CAPES; SciELO - Scientific Electronic Library Online; Web of Science; e KCI - Korean Journal Database. A análise considerou os artigos elaborados em língua portuguesa e inglesa publicados a partir do ano de 2007 até o ano de 2022, assim como a quantidade de citações, a classificação Qualis CAPES e o fator de impacto dos periódicos. Com base nisso, oito artigos foram selecionados, sendo predominantes as produções científicas em inglês. Por meio dos estudos, notou-se que as potencialidades dos programas estão relacionadas com o abastecimento de água para 64% das famílias por meio da construção de cisternas para o aproveitamento das águas pluviais, a disponibilização de água e produtos de higiene em 44% das escolas, bem como na instalação de latrinas para a eliminação dos dejetos e na gestão comunitária dos serviços. No entanto, as limitações envolvem a falta de auxílio técnico para prestação dos serviços, a insuficiência na capacidade dos sistemas de reservação de água e a morosidade do Estado brasileiro. Portanto, conclui-se que as experiências dos programas e políticas de saneamento rural apresentaram benefícios para as comunidades e, ainda, evidenciou os desafios para garantir a universalização do saneamento.

A escassez de dados de monitoramento fluviométrico é um grande desafio na gestão dos recursos hídricos é de fundamental importância conhecer o comportamento dos rios para fins de planejamento de atividades humanas. A região da bacia hidrográfica do rio do Grande/Ba destaca-se como uma grande produtora agrícola, além de apresentar um elevado crescimento demográfico e econômico, assim apresentando um intensivo uso da água. A regionalização é uma importante técnica para se estimar vazões em regiões desprovidas de dados, neste sentido, o presente artigo teve como objetivo avaliar um conjunto de características físicas das sub-bacias do rio Grande/Ba para a obtenção de um modelo de regionalização de vazões. Para tanto, utilizou-se informações oito estações fluviométricas da região disponibilizadas pela Agência Nacional de Águas (ANA), e considerando-as como exutórios das sub-bacias, analisou-se as características físicas a área de drenagem da bacia (A), comprimento do rio principal (L), declividade média do rio principal (S), densidade de drenagem (D), desnível (H) e perímetro (P). A partir do método de regressão avaliou-se o grau de correlação de cada conjunto de características físicas com o conjunto de vazões das estações. Os resultados mostraram que as variáveis de área de drenagem da bacia e perímetro foram características físicas que melhor descrevem a relação de com as vazões, assim compondo o modelo final. A avaliação para estimativas de vazões apresentou um coeficiente de determinação de 0.94, erro médio de 11,32,  e a análise global apresentou coeficiente Nash-Sutcliffe de 0,87.

Published: October 2023

A modificação do uso do solo, por meio da substituição da cobertura vegetal por pastagem exógena, juntamente ao crescimento urbano, ocorrida ao longo das últimas décadas, em Goiás, influenciou e impacta, de forma marcante, a qualidade da água. A bacia hidrográfica do Ribeirão Vereda, em Aragoiânia, reproduz essa condição. Nesse sentido, este estudo tem como objetivo realizar uma análise quali-quantitativa do uso e cobertura do solo nesta bacia, associando com as características apresentadas pela água, utilizando recorte temporal entre os anos de 2010 a 2019 e os principais impactos ambientais decorrentes desse processo. Para alcançar esse objetivo, utilizaram-se os resultados das análises de substâncias orgânicas e os resultados físico-químicos e bacteriológicos na água bruta do ribeirão Vereda. Há relações entre uso do solo pela agricultura com a quantidade de fosfatos, como também a influência do espaço urbano, contribuindo com a maior quantidade de cloretos, tal como a área de solo exposto e a concentração de cloretos, além da denotação entre quanto maior a área de vegetação menor é a Demanda por Oxigênio (DBO). Os parâmetros de qualidade da água vêm sofrendo alterações consideráveis devido aos distúrbios ocasionados pelo significativo domínio (em torno de 70%) da pastagem na bacia. Além disso, constataram-se agrotóxicos na água bruta, porém, observa-se um declínio desses elementos a partir de 2019.

Published: October 2023

O presente artigo teve por objetivo avaliar os modelos deposicionais vigentes e compreender o processo de sedimentação no reservatório da UHE Foz do Rio Claro. A escolha desta bacia para realização da pesquisa, se deve à sua grande importância para a região, sendo uma das principais fontes para o abastecimento público e geração de energia elétrica. O barramento de um rio para qualquer atividade ocasiona diversas mudanças na dinâmica fluvial de uma bacia hidrográfica; diminui a velocidade de escoamento e a capacidade de transporte de sedimentos, ocasionando a sedimentação e consequente assoreamento. Foram estabelecidos e analisados testemunhos verticais coletados em 23 pontos de amostragem do reservatório, e em dois períodos distintos. A identificação dos possíveis modelos deposicionais e sedimentação do reservatório foi realizado por meio da análise de fácies e análise textural, do material depositado. De acordo com a análise granulométrica, o material arenoso se encontra depositado no trecho inicial do reservatório, e a deposição de material silte-argiloso ocorre próximo ao barramento do reservatório. As fácies predominantes no reservatório são as silto-argilosas que dão origem ao modelo deposicional de leito.

Published: October 2023

Through the analysis of legal texts and official documents on the environmental refuge, it is observed that these diplomas approach the refuge only under its primitive concept, established in the Convention on the Status of Refugees, without major innovations. Moreover, the environmental refuge does not appear in legal instruments. In situations where the environment is identified as a driving factor for migration, the economic context of the affected regions is a decisive and essential element of displacement. Therefore, the research in question aims at discussing the economic context of environmental refuge, based on the cyclical phenomenon of drought in northeastern Brazil and environmental disasters in the cities of Mariana and Brumadinho. The discussion on political and social issues that enhance the damage to the environment should receive special attention in the refuge's agenda, in order to corroborate the connection between economic vulnerability and environmental refuge.

A retrospective cohort study of human papillomavirus (HPV) genotypes in women with abnormal Pap smear cytology in Turkey
Authors: Beka Hayati
Published: October 2023

Background/Aim: The most common genotypes of human papillomavirus (HPV) in patients with cervical cancer worldwide are HPV16 and HPV18. The persistence of these genotypes is associated with cervical cancer and detection, and HPV genotyping, particularly in women with abnormal Pap smears, has become a crucial tool for cervical cancer screening, diagnosis and management. We evaluated the overall prevalence of HPV in women with abnormal Pap smear cytology and also investigated age-specific HPV prevalence and HPV genotype distribution.
Methods: We analyzed 716 cervical smear specimens in this retrospective cohort study. Cytological diagnoses of typical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesions (LSILs), and high-grade squamous intraepithelial lesions (HSILs) were made utilizing the Bethesda System. The Papanicolaou method was used for the staining of the Pap smears. The specimens were pre-screened for HPV DNA positivity using an HC2 assay (Qiagen, USA). After the pre-screening, a Cobas 4800 HPV test system (Roche Diagnostics GmBH, Germany) was used to genotype the HPV-positive samples.
Results: Of the 716 cervical smear samples, 520 (72.6%) were found to be HPV-negative. Among the HPV-positive samples, 106 (23.2%), 57 (28.8%) and 33 (53.2%) were identified from 456 ASCUS, 198 LSIL and 62 HSIL cases, respectively. These findings revealed a gradual decrease in HPV prevalence with increased cytological grade (P<0.05). For high-risk, low-risk and high-risk/low-risk HPV types, 76 (38.8%), 78 (39.8%) and 42 (21.4) were positive according to the HC2 assay, respectively (P<0.05) Only 117 of the 196 HPV-positive samples were found to be HPV-positive with the Cobas 4800 HPV test system. HPV16 was the most prevalent type detected by the Cobas 4800 HPV test: 55 out of 117 HPV-positive smear samples across all age groups (47%). HPV16 was significantly more frequently detected in the HSIL samples than HPV18 (P<0.05). The prevalence of HPV was the highest in women with ages between 29 and 38 (71/196, 36.22%) and declined with age.
Conclusion: We found that HPV16 and HPV18 were the most prevalent genotypes of HPV in a cohort of Turkish women; HPV16 was most frequently detected in HSIL samples from women with ages between 29 and 38. We conclude that investigating the incidence of HPV16 and HPV18 genotypes will be important for implementing new programs and protocols to reduce the incidence of cervical cancer. These data may contribute to the development of preventive strategies to reduce the cervical cancer burden in Turkey.
BIOSPHERIC ASPECTS OF SWAMPY SOIL FORMATION
Authors:   Tomsk State Pedagogical University, Inisheva Lidiya
Published: October 2023

The article shows that each period of the evolutionary process of the biosphere formation on Earth corresponds to one form of soil formation, namely: underwater (“hydrozemic”), swampy (“atmozemic”), and terrestrial (“lithozemic”). The ancient swamp soil formation is considered, in addition to biomass deposition, to take part in the formation of the oxygen-containing composition of the planet’s gaseous envelope and the release of organisms from the aquatic environment to land. It has been determined that the process of paludification and swamp soils in the past and at present did and do perform the same biospheric functions and should include the entire genetic profile up to the basal rock in the concept of “peat soil”. On the example of the central part of Western Siberia, the process of paludification in the Holocene period is considered. This process is defined as a single, irreversible, progressive process of conjugated changes in their biotic and abiotic components. This ensures autonomy in the development and preservation of mires as a special type of the biogeocenotic cover of Earth. It is shown that the differences in the mire complexes of different botanico-geographical zones and subzones reveal the chronological boundaries of the transformation of swamp biogeocenoses of eutrophic types into mesotrophic and oligotrophic ones. It has been determined that the process of paludification in the taiga zone of the West Siberian Plain is of aggressive nature and the expected warming is a temporary warm period in the interval of cyclical climate.

“TRUE SEEKER OF THE MOUNTAINS SOUL” AND THE WEALTH OF THE “LAKE OF MOUNTAIN SPIRITS”: G. I. CHOROS-GURKIN IN THE CONTEXT OF THE 101-YEAR HISTORYOF THE SANATORIUM “UZKOE”
Authors: Trubetskaya Natalya
Published: October 2023

The article turns to one of the most interesting pages in the 101-year history of the sanatorium “Uzkoe” (Federal Research and Clinical Center of Reanimatology and Rehabilitation) through the prism of the life and creative activity of the outstanding Altai artist Grigory Ivanovich Choros-Gurkin (1870-1937). His “Altai” (or «Lake of mountain spirits») painting created in 1916 for the honorary Academician Nikolai Alexandrovich Morozov (1854-1946) are one of the brightest pearls of the art collection of the sanatorium “Uzkoe”. Both behind the plot of the painting, where the ancient Oirot legend is intertwined with the comprehension of the secrets of science, and behind the process of creation and the further fate of the canvas itself, an amazing story is hidden which to this day, revealing new facets, disturbs the inquisitive mind of researchers. The main role in this story will belong to “reason and solid analysis”.

El siguiente trabajo de investigación pretende identificar cuáles son los factores que mantienen latente la amenaza que se cierne sobre líderes defensores de derechos humanos de los municipios de María la  Baja, San Jacinto, Carmen de Bolívar y San Juan Nepomuceno, pertenecientes a la región de los Montes de María del departamento de Bolívar, y a partir de allí emitir recomendaciones de políticas públicas en aras de lograr un avance integral en las medidas tendientes a la mitigación de la amenaza que se cierne sobre los defensores. Dicha investigación surge de la necesidad de hacer frente al escenario de riesgo advertido por la Defensoría del Pueblo desde el año 2014, y reiterado por la misma en el año 2019 y 2020, en donde se evidencia la persistencia del conflicto armado en dichos territorios, bajo modalidades que tienden a confundirse con acciones de delincuencia común. Con el estudio de los resultados de nuestra investigación, divididos en siete categorías de análisis, veremos  que el escenario actual de transición resultado de la negociación entre el Gobierno Nacional y las FARC- EP, orientado a la dejación de armas y la incursión en la arena política de este grupo insurgente, ha planteado cambios importantes en las dinámicas locales del territorio montemariano, en donde ha quedado evidenciado una reconfiguración del conflicto armado corroborado con la presencia de grupos ilegales alzados en armas en los territorios, que propician  ataques sistemáticos a líderes sociales en tanto  medio para desestructurar y disolver los procesos organizativos de todo un colectivo.

Published: October 2023

Cabai merupakan produk hortikultura yang banyak dikonsumsi dalam bentuk segar dan olahan, cabai olahan bisa dalam bentuk pasta, kering dan serbuk. Saat ini Indonesia masih mengimpor cabai kering karena harga cabai kering impor lebih murah dari cabai kering lokal. Biaya produksi usaha cabai dapat diusahakan dengan menerapkan manajemen teknologi budidaya yang tepat. Salah satu cara untuk menekan biaya produksi adalah dengan menggunakan varietas cabai yang dapat di panen dalam kondisi kering di pohon, sehingga dapat mengurangi biaya pengeringan pada pascapanen. Sementara itu produksi cabai dapat ditingkatkan dengan menggunakan jarak tanam rapat, sehingga hasil per satuan luas akan lebih tinggi.

Permasalahan penduduk merupakan salah satu dari permasalahan utama negara berkembang seperti di Indonesia. Di masa pandemi, permasalahan penduduk semakin kompleks dan serius. Penelitian ini bertujuan Untuk menganilis dinamika kondisi kependudukan mempengaruhi perubahan aspek ekonomi di masa pandemi COVID-19 di Provinsi NTB. Dalam penelitian ini digunakan variabel CBR (Tingkat Kelahiran Kasar) ,CDR (Tingkat Kematian Kasar), NMR (Tingkat Migrasi Bersih) dan data PDRB harga berlaku konstan 2010 dari tahun 2011-2021, serta menggunakan alat analisis regresi linear berganda. Tingkat kelahiran berpengaruh negatif dan signifikan terhadap PDRB, artinya jika terjadi kenaikan 1 satuan CBR, maka akan terjadi penurunan sejumlah 0,00046 satuan dari PDRB. Bila rasio ketergantungan makin rendah, maka makin rendah beban yang ditanggung oleh penduiduk usia produktif untuk menanggung biaya penduduk yang memiliki usia tidak produktif semakin rendah. Tingkat kematian berpengaruh positif namun tidak signifikan terhadap PDRB, artinya jika terjadi kenaikan 1 satuan CDR, maka terjadi kenaikan sejumlah 0.006155 satuan dari PDRB. Hal ini menunjukkan bahwa pengaruh tingkat kematian terhadap PDRB adalah positif namun tidak signifikan. Migrasi penduduk (NMR) berpengaruh negatif dan signifikan terhadap PDRB, artinya akan ada kenaikan 1 satuan NMR apabila ada penurunan sejumlah 0,00037 satuan dari PDRB. Di NTB mempunyai trend negatif yang mana angka migrasi keluar lebih banyak dari pada migrasi masuk. Hal ini menjelaskan bahwa lebih banyak penduduk yang keluar dan mengindikasikan perekonomian NTB, khususnya lapangan pekerjaan, yang dirasa belum memenuhi standar hidup dibandingkan wilayah lain.

Used cooking oil is obtained from the residue of the frying process, which has been used repeatedly where the fatty acids are increasingly saturated and the triglyceride content breaks down into volatile and non-volatile components that dissolve in oil. Used cooking oil waste can cause an increase in COD and BOD levels in waters, resulting in the death of aquatic biota. The aims of this study were (1) to determine the optimum contact time of activated charcoal d combination of citronella sticks on decreasing levels of free fatty acids, (2) to determine the optimum contact time of activated charcoal d combination of citronella sticks on decreasing peroxide numbers, (3) to determine the average percentage of free fatty acid reduction and peroxide value in the clarification of used cooking oil using activated coconut shell charcoal combined with lemongrass stems. This research method is a laboratory experiment with despising, neutralization, and bleaching stages. The results showed that the average decrease in optimum free fatty acid levels occurred at 60 minutes of contact time, namely A3 at 73.86%, B3 at 66.67%, and C3 at 82.74%. The average decrease in the optimum peroxide number occurred at a contact time of 60 minutes, namely A3 of 57.16%, B3 of 52.85%, and C3 of 49.68%. So, the coconut shell-activated charcoal combined with lemongrass stems effectively clarifies the used cooking oil. In the future, it is necessary to vary the absorbent particle size to improve the quality of the waste cooking oil so that it can be reused.

Differentiated learning is a form of learning that is oriented to the needs of students. This research is a classroom action research which aims to determine the effect of implementing visual, auditory, and kinesthetic (VAK) learning style-based differentiation in the Problem Based Learning (PBL) model on students' physics learning activities and outcomes. The material used is global warming. This research was conducted in class X-2 of State High School 3 Jember for the 2022/2023 Academic Year. The subjects of this study were of 36 students who were divided into three VAK learning style profile categories. This research includes quantitative descriptive research. The research data collection method used a Likert scale learning style questionnaire, activity observation sheets and written tests to obtain students' physics learning outcomes. The design used in this study was the Tagart and Kemmis model cycles and the data obtained was analyzed using classical learning completeness. The results showed that there was an increase in student learning activities by 20.14% and an increase in student physics learning outcomes classically by 25% and the average level of mastery learning was above the minimum completeness criteria with an increase in the average score of 6.06. Based on the results of the study, it can be concluded that the application of the PBL learning model based on VAK learning style differentiation can increase student activity and learning outcomes.

Background: The benefits of vitamin C treatment for erectile functions during prepubertal crude oil-contaminated water (CCW) ingestion are unknown. We currently considered the import of vitamin C supplement during prepubertal crude oil-contaminated water ingestion on adult erectile mechanisms in Wistar rats.

Materials and methods: 18 prepubertal male rats were divided into three groups and given saline, 2.5 ml CCW, and 2.5 ml CCW + vitamin C (10 mg/kg), separately, until adulthood. Cavernosa tissue responses to phenylephrine, acetylcholine, potassium chloride, and responses after incubation with glibenclamide, nifedipine, methyl blue, and indomethacin were investigated. Serum testosterone and the cavernosa oxidative biomarkers were determined.

Results: Testosterone and catalase activity were significantly reduced in CCW group, while malondialdehyde activity was significantly increased. Potassium significantly increased cavernosa contraction in CCW-treated group. Incubation of the cavernosa with nifedipine and indomethacin reduced the percentage of relaxation in CCW group. When compared to the vitamin C-supplemented groups, incubating the cavernosa with methyl blue and glibenclamide markedly reduced relaxation in CCW.

Conclusions: Prepubertal CCW ingestion impaired adult cavernosa ATP-sensitive K+ channels, receptor and voltage-operated calcium channels, guanylate cyclase, and prostaglandin activity. Vitamin C administration reduced contractile impairments by increasing antioxidant activity in the cavernosa.

Published: October 2023

Listing spare homes as tourist accommodations on applications like Airbnb has boosted consumers’ adoption of the digital sharing economy (DSE). This research paper aims to develop a variable selection methodology for factors influencing consumers’ adoption intention of DSE applications like Airbnb and UBER. The symmetrical adoption pattern (SAP) will assist industry practitioners in designing an accurate investment pattern for the available resources. The research examines feedback from travellers regarding utilized services to develop SAP. The authors adopt NCapture as a data extraction tool and NVivo 12 as a data analysis tool to develop SAP as a variable selection methodology. Sentiment, thematic, and cluster analysis methods of qualitative analysis were employed to extract 19 distinct variables of SAP out of available data and adapt it into the six constructs of the unified theory of acceptance and use of technology (UTAUT2). By identifying the ideal variable for each construct with SAP, the performed study also aims to broaden the understanding of theories linked to the UTAUT2 model.
Effect of Dietary Supplementation of Rhus coriaria Grind Seeds and ‎Exogenous Fibrolytic Enzymes on Some Blood Lipids and Ruminal ‎Fermentation Parameters ‎of Awassi Male Lambs

Published: October 2023

This study was conducted to assess the potential dietary effect of grind seeds of Rhus coriaria ‎‎(gsRC) with and without exogenous fibrolytic enzymes (EFE) on some lipid profiles ‎and ruminal fermentation characteristics of Awassi male lambs. A total of twenty-four Awassi ‎male lambs weighing 21.56±0.77 kg at 3-4 months of age were randomly divided based on BW ‎into four groups with six animals each. Dietary treatments were provided to lambs for 4 ‎months as follows: control group, fed on a concentrate diet at the rate of 2.5% ‎BW with alfalfa hay daily; gsRC-15 group, fed the control group diet supplemented ‎with 15 g/head dried grind seeds of Rhus coriaria daily with diet; EFE-5 group, fed the control ‎group diet supplemented with ‎‎5 g/head of EFE daily with diet; gsRC-EFE group, fed on the ‎control group diet supplemented with ‎15 g/head‎dried grind seeds of Rhus coriaria and 5 g/head ‎of EFE daily with diet. The results showed that serum cholesterol and triglycerides ‎significantly ‎(P‎‎<0.05) reduced in the treated groups compared to the control group, particularly observed in 3rd and 4th months of the experiment. Comparable results ‎were observed for lambs fed on EFE alone in the 4th month of the study. The treatment groups showed significantly (P‎‎<0.05) lower ruminal pH levels at the beginning, in the middle, and at the end of the experiment. At the middle and end of the study's last month, the volatile fatty acids (VFAs), ammonia nitrogen (NH3-N), and microflora activity of the rumen were significantly (P‎‎<0.05) higher in the treated groups compared to the control group. It can be ‎concluded that sumac seed powder and EFE can be used in combination or alone as an effective ‎feed additive to improve lipid profiles and rumen fermentation parameters in Awassi male lambs‎‎.

This research aimed to conduct a pyrolytic conversion of waste plastics using an African seed-based activated carbon catalyst. The process description to produce activated carbon from African star apple includes removing and drying seed husks, grinding, and preparing activated carbon (AC). The plastic waste materials used for the catalytic pyrolysis process were waste Low-Density Polyethylene (LDPE) and High-Density Polyethylene (HDPE) plastic, which were sourced from Liberation Stadium Road, GRA Phase IV, Port Harcourt, Rivers State. The effects of activated carbon (AC) as a catalyst on fuel production and gasification efficiency were also evaluated. Proximate and ultimate analyses were conducted on the AC to determine its composition. The results showed that the AC had high fixed carbon content and low volatile matter and ash contents. The experiments also showed that the products' density, calorific value, cetane number, and kinematic viscosity were within the range of diesel fuel specifications. However, the water, flashpoint, acid number, ash, and nitrogen content were higher than diesel fuel. The addition of AC catalyst improved the properties of the pyrolyzed products by reducing the water content, acid number, and ash content.
