В статті наведено дані щодо стану кишкової мікробіоти у хворих із цукровим діабетом 2 типу та гіперамоніємією. Метою нашого дослідження було вивчити стан мікробіоти кишківника у пацієнтів з цукровим діабетом 2 типу з гіперамоніємією та оцінити вплив багатоштамного пробіотику на рівень аміаку.
Матеріали та методи. У дослідження було включено 25 пацієнтів, з них 18 осіб з гіперамоніємією (11 жінок та 7 чоловіків) та 7 без гіперамоніємії (7 жінок). Середній вік пацієнтів з гіперамоніємією становив 62,10 ± 1,80 роки, рівень HbA1c 7,06 ± 0,23 %, середній рівень аміаку – 43,64 ± 1,77 мкмоль/л. Для корекції кишкової мікробіоти пацієнти з гіперамоніємією отримували комплексний пробіотик (14 штамів, сумарно 2,0×109 КУО пробіотичних мікроорганізмів) 2 рази на добу протягом 1 місяця.
Результати. Було встановлено, що у пацієнтів з цукровим діабетом 2 типу з гіперамоніємією визначався дисбіоз кишківника зі зменшеною кількістю представників родів Lactobacillus та Bifidobacterium, та підвищеним вмістом бактерій родів Escherichia та Pseudomonas. Після проведеного лікування пробіотиком кількісна складова мікробіоти змінювалася, а саме, збільшувалася кількість Bifidobacterium spp., Lactobacillus spp., Escherichia coli, Enterococcus spp. та Bacteroides spp. і зменшувалася присутність бактерій з уреазною активністю, що призвело до вірогідно значущого зменшення рівня аміаку на 7,0 мкмоль/л та рівня глікемії натще на 1,33 ммоль/л.
Висновок. Додаткова терапія багатоштамними пробіотиками покращує стан мікробіоти кишківника у хворих на цукровий діабет 2 типу з гіперамоніємією, вірогідно знижуючи рівень аміаку та рівень глікемії натще.

Published: December 2024

This study aims to examine the effect of discount and cashback programs on the frequency of purchases on the Shopeefood application. The background of this research is the rapid development of e-commerce in Indonesia, where Shopee remains the leader with the highest number of monthly visits by 2023. Shopeefood, as one of the main services on this platform, uses various promotional strategies to attract more users, one of which is the discount and cashback program. This study highlights that Shopeefood's strategies, especially the use of discounts and cashback, contribute to an increase in transactions. Discounts provide an immediate price cut that appeals to consumers while cashback offers a financial incentive in the form of a refund that encourages consumers to shop more frequently in the future. However, there are some complaints from consumers regarding the relatively long period of receiving cashback and the less transparent application process, which may affect their level of satisfaction. Through a quantitative approach with multiple linear regression analysis and hypothesis testing, this study found that discount and cashback programs have a significant influence on the frequency of purchases at Shopeefood. The results of this study are expected to provide valuable insights for companies to develop more effective marketing strategies, not only in increasing purchase frequency, but also in building consumer loyalty amid increasingly fierce competition in the food delivery service industry.
Vena poplítea, un acceso alternativo para el inicio de hemodiálisis en pacientes en decúbito prono durante la pandemia de COVID-19
Authors: Arroyo Manuel F. , Abreo Salvador , Villa Jaime , Rebolledo Carlos , Camacho Jorge
Published: December 2024

Introducción: la lesión renal aguda que se presenta en la enfermedad crítica de los pacientes infectados por SARS-CoV-2 requiere de terapia de reemplazo renal, así quedó demostrado según grandes estudios en China e Italia, donde el 12?% de la muestra requirió de terapia de sustitución renal.
Objetivo: dar a conocer el uso del acceso venoso poplíteo para la colocación de catéteres en pacientes críticos en posición de decúbito prono, en quienes se iniciará terapia de reemplazo renal, por lo que se imposibilitará que adopten la posición de decúbito supino.
Presentación del caso: paciente joven de 42 años de edad, hospitalizado por neumonía causada por COVID-19, pocos días después presenta SDRA severo, quien requiere de ventilación mecánica y estrategia de posición prono; al tercer día desarrolla lesión renal aguda, por lo que se inició terapia de reemplazo renal, aunque debido a su trastorno de oxigenación e inestabilidad hemodinámica fue imposible el decúbito supino, por lo que se decidió colocar catéter temporal para hemodiálisis en la vena poplítea izquierda, guiado por ultrasonido.
Discusión y conclusión: al tener en cuenta este caso, el paciente no podía colocarse en posición decúbito supino por la hipoxemia severa, además, los accesos venosos de primera línea como yugulares, femorales y subclavios se encontraban limitados por la posición. El acceso venoso poplíteo es seguro, ofrece ventajas como lograr la comodidad del operador al insertar el catéter bajo técnica ecoguiada, siendo una vía de fácil acceso y, adicionalmente, presenta menos riesgo de contaminación, por lo que se recomienda este acceso venoso de manera alternativa en este grupo de pacientes.
Addressing Gender-Based Violence to Support HIV Prevention Efforts: A Review
Authors: Obeagu Emmanuel Ifeanyi
Published: December 2024

Gender-based violence (GBV) is a significant global health issue that exacerbates the spread of HIV, particularly among women and vulnerable populations. The links between GBV and HIV transmission are multifaceted, as violence increases individuals' exposure to unprotected sex, limits access to healthcare, and fosters environments of stigma and disempowerment. Victims of GBV, particularly women, may face greater barriers to HIV prevention and care, putting them at higher risk of both HIV infection and poor health outcomes. The intersection of gender inequality and violence creates a cycle that hinders effective HIV prevention efforts and impedes the overall fight against the epidemic. Addressing GBV is crucial to improving HIV prevention strategies. Integrating gender-sensitive approaches into HIV prevention programs can help mitigate the risk of HIV transmission. Key strategies include community-based interventions to shift harmful gender norms, comprehensive sexual and reproductive health services that address both GBV and HIV needs, and strengthening legal frameworks to protect survivors. Empowering individuals through education about sexual rights and HIV prevention is also essential, as is involving men and boys in the promotion of gender equality. These combined efforts can reduce both GBV and HIV transmission by addressing the root causes and providing support for survivors.

One Step at a Time: Incremental Approaches to HIV Prevention
Authors: Obeagu Emmanuel Ifeanyi
Published: December 2024

HIV prevention remains a global priority, with diverse strategies continuously developed to address the needs of high-risk populations. Incremental approaches—emphasizing gradual, step-by-step advancements—are gaining traction as an effective method to tailor interventions, increase accessibility, and foster long-term engagement. These strategies build on existing resources, adjust to unique local contexts, and prioritize community involvement, making them especially impactful in resource-limited or culturally diverse settings. By setting measurable, short-term goals, incremental approaches offer a sustainable pathway for reducing HIV transmission rates. One significant example of incremental HIV prevention is the phased implementation of Pre-Exposure Prophylaxis (PrEP), which has shown remarkable results when introduced progressively to high-risk groups. Alongside PrEP, behavioral interventions such as safe-sex education and harm reduction for injecting drug users are adapted incrementally to shift cultural norms and reduce stigma. Biomedical innovations, like microbicides, are similarly introduced in stages, with user feedback and adherence monitored to enhance real-world effectiveness. By allowing for community-specific refinements, these interventions become more accepted and impactful.

Authors: Chitra K K , Jat Rakesh Kumar
Published: December 2024

The current study is done on plant extracts as antipsychotic medication in ayurvedic formulation. The hallucinations are induced by electro shock therapy or apomorphine. After induction of hallucinations the plant extract is administered as standard group, control group and simple group of six albino rats and the results are screened and analyzed with standard drug comparision. Pre-treatment of MEIR (methanolic extract of Ipomoea reniformis) for 15days at the dose of 200 and 400 milligram per kilogram body weight was used to evaluate antipsychotic activity. The antipsychotic activity was also studied against Apomorphine induced stereotype behavior in rats, Pilocarpine induced purposeless chewing in rats and Apomorphine induced climbing behavior in mice. In pre-treatment studies of antipsychotic activity, MEIR at the dose of 200 and 400 milligram per kilogram body weight significantly (p<0.001) reduced the stereotyped behavior against Apomorphine induced stereotypy behavior model. In Pilocarpine induced purposeless chewing behavior, MEIR at the dose of 200 and 400 milligram per kilogram body weight significantly (p<0.01) decreased chewing behavior and in Apomorphine induced climbing behavior, MEIR significantly (p<0.001) reduced the climbing activity at the dose of 200 and 400 milligram per kilogram body weight. The results of the Pr (+) study suggest that the MEIR possess antipsychotic activity in rats and mice. The results of each activites are compared with standard medicament and evaluated.

Classification of diabetic retinopathy grades using CNN feature extraction to segment the lesion
Authors: M. Swathi  , S.Venkata Lakshmi
Published: December 2024

Diabetes's microvascular aftereffect, diabetic retinopathy (DR), is the primary cause of eyesight loss in the globe. In order to prevent vision impairment and to intervene promptly, early detection and precise classification of DR severity are essential. Using standard methods for diagnosing DR requires ophthalmologists to grade cases by hand, a process that can be laborious, subjective, and subject to observer error. In supervised learning task of classification, data instances are classified into predefined classes based on features. The relation between the traits and the classes can be found from the labelled data. After the training is completed, the classes of the unseen data. The frequent reason found for the loss of vision in diabetic retinopathy (DR) is found to be diabetes. Visual damage can be prevented by identifying the degree of DR at right time. For the grading of the DR, deep learning techniques are found to be very effective with maximum possible accuracy. The proposed model is useful in accurately classifying the DR images using the feature extraction with lesion segmentation, by implementing the patterns in the DR images. ReLU activation function is used in the proposed model. CNN feature extraction is used for the important feature extraction by applying the Convolution layers, and edges, textures, and forms are identified. As the model proceeds layer by layer, complicated patterns in the photos can be learned by the model, and can be analysed better. The features of the photos were extracted and found useful in segmentation and classification. ReLU is helpful in improving the convergence and also found useful in learning the patterns. Among the other activation functions, ReLU has higher computational efficiency and therefore is used in the model, which suits well for the DR application. A strong framework is proposed for the classification of the DR grade, for the lesion segmentation and CNN feature extraction. DR categorization using the proposed model is evaluated by data visualization of the important calculated metrics and found to be very effective.

Authors: Fernandes Gustavo Vicentis de Oliveira , Machado Cláudia Filipa Azevedo , Fernandes Juliana Campos Hasse , Seabra Mariana , Figueiredo Andreia
Published: December 2024

Purpose: This study aimed to compare the surface roughness among 3 types of glass ionomers (GI) before (no polishing) and after polishing with three different materials.Methods: 20 discs for each GI group were obtained (A-Ionolux; B-IonoStar Plus; C-Ketac). Those groups were subdivided according to finishing and polishing: subgroups 1 (control) - no polishing, 2 - polishing with prophylactic brush and pumice paste, 3 - Enhance tips with water, and 4 - Sof-Lex system with Easy Glaze and polymerization. For each disc face, the total distance analyzed was 2.88cm (6x48mm). Then, the roughness was compared using the Kruskal-Wallis with Bonferroni test, with significant data if p<0.05.Results: The mean of roughness within Group A was lower for subgroup 4 (1.07±0.54 μm) and higher for subgroup 2 (2.33±1.17 μm). Within group B, B4 had the lowest mean of roughness (0.93±0.38 μm) and B2 (1.24 ± 0.78 μm) the highest roughness. Within group C, Group C4 had the lowest mean roughness value (0.84±0.54 μm), and C3 had the highest mean (2.48±1.05 μm). After polishing, subgroup 4 had the general lowest values for surface roughness (mean Ra 0.95), followed by subgroup 1 (Ra=1.27), subgroup 2 (Ra=1.89), and higher values for subgroup 3. All intragroup analysis for A, B, and C were statistically significant. Group A presented the highest roughness (p<0.05), and no statistically significant evidence existed between groups B and C (p>0.05).Conclusion: The reduction of the roughness of the materials is dependent on their composition and the polishing and finishing techniques applied.

MÉTODOS TERAPÊUTICOS PARA DESPIGMENTAÇÃO MELÂNICA GENGIVAL: TÉCNICA CIRÚRGICA COM LÂMINA DE BISTURI, ABRASÃO COM INSTRUMENTO ROTATÓRIO E ABLAÇÃO A LASER – REVISÃO DE LITERATURA
Authors: Gripp Renata Farias , Zarranz Laila , Gallito Marco Antonio , Lomardo Priscilla , Mandarino Denize
Published: December 2024

A hiperpigmentação melânica ocorre devido à deposição anormal de melanina na camada basal e suprabasal do epitélio, criando uma aparência escurecida. É fisiológica, por isso não representa dano à saúde, podendo ser apenas uma queixa estética do paciente. O objetivo deste trabalho foi realizar uma revisão de literatura narrativa sobre o uso da técnica cirúrgica com bisturi, da abrasão com instrumento rotatório e da ablação com laser como métodos para realizar a remoção da hiperpigmentação melânica gengival de etiologia fisiológica. Muitas técnicas têm sido utilizadas para fazer a despigmentação, diferentes resultados e fatores, como conforto do paciente, cuidado pós-operatório e recorrência, têm sido apresentados. A técnica cirúrgica com bisturi é considerada o padrão ouro devido aos seus bons resultados, material de fácil acesso e baixo custo. A abrasão com instrumentos rotatórios não requer nenhum equipamento ou material sofisticado, é relativamente simples e segura. E a terapia a laser é uma modalidade de tratamento eficaz, minimamente invasiva, com trans e pós-operatório confortável. Entretanto, são necessários mais estudos sobre o uso da abrasão com instrumento rotatório que acompanhem os pacientes em longo prazo e pesquisas que descrevam o uso e resultados proporcionados pelos diversos tipos de laser de alta potência. Tendo em vista a presente revisão de literatura pode-se concluir que a repigmentação não ocorre por uma média de um a dois anos. Porém, são necessários mais estudos para especificar qual técnica apresenta menor índice de repigmentação.

Published: December 2024

The flexural resistence is one of the most used test in researchs of mechanical characterization of resin composites for dental restoration. ISO 4049 photopolymerization technique performed static application stages of light tip. To polymerize the entire area of ​​the specimen some areas must receive extra radiation. These areas with extra radiation are called overlap areas. In an attempt to remedy this problem, this research compared the ISO method with a new method using constant movement (CM) during photopolymerization. Twenty specimens (SPs) were produced with 25 x 2 x 2 mm, for each group, 10 specimens being polymerized by the static technique recommended by the ISO-4049 and 10 specimens polymerized by the CM technique for each LED curing light used. After Tukey's statistical analysis, it was found that there was no statistical difference in relation to flexural strength (FS) and for the flexural modulus of elasticity (EF). However, the standard deviation of both FS and EF were much lower in MC than in ISO. Therefore, the photopolymerization by CM of the samples for the flexural strength test proved to be a possible solution to the problem of overlap of the technique proposed by ISO.

PACIENTES PORTADORES DA DOENÇA DE CHAGAS: MANEJO ODONTOLÓGICO: UMA REVISÃO NARRATIVA DA LITERATURA
Authors: da Silva Dayane de Araujo , de Matos Ivana Firme , Cunha Carlos Eduardo dos Santos , Costa Michele Rosas Couto , Pola Paulo Henrique
Published: December 2024

A doença de Chagas é uma infecção parasitária sistêmica causada pelo protozoário Trypanosoma cruzi (T. cruzi), descoberta em 1909, pelo médico e pesquisador brasileiro, Carlos Chagas. O objetivo deste estudo é discutir sobre as manifestações clínicas da Doença de Chagas e suas importantes implicações na Odontologia. Este artigo é baseado em um estudo de revisão narrativa da literatura, de abordagem qualitativa. O levantamento dos artigos foi realizado na base de dados PubMed, LILACS e SciELO totalizando 13 estudos utilizados para o complemento da pesquisa. A Doença de Chagas é transmitida pelo contato com as fezes do inseto vetor, chamado de "barbeiro" no Brasil. Quando a célula, a qual o protozoário invadiu, se rompe, os novos microrganismos procuram novas células para habitar, percorrendo o sangue e a linfa, atingido o coração, tubo digestivo e plexos nervosos. Ao afetar o tecido coronariano, os microrganismos instalam-se nas células cardíacas, principalmente nos fagolissomos, além de afetar o sistema cardíaco, a doença de Chagas pode apresentar envolvimento de mais dois importantes sistemas do corpo humano: sistema estomatognático e digestivo. No atendimento a pacientes chagásicos, que apresentam comprometimento cardíaco, o Cirurgião-Dentista precisa realizar anamnese bem detalhada a fim de se conhecer mais sobre a condição sistêmica do mesmo, protocolos de redução de estresse são imprescindíveis considerando que o atendimento odontológico induz um quadro de ansiedade nos pacientes. O conhecimento prévio sobre a doença de chagas é mandatório para o Cirurgião-Dentista, visto que as manifestações bucais da doença podem impactar diretamente na qualidade de vida desses indivíduos.

Authors: Pereira de Araújo Rayane , Pereira de Araújo Matheus , Gomes da Silva Esdras , Pinto de Medeiros Juliana
Published: December 2024

O objetivo desta revisão integrativa foi elaborar uma avaliação qualitativa da literatura existente sobre as modalidades de tratamento utilizadas para cistos dentígeros em pacientes pediátricos. O  presente estudo trata-se de uma revisão integrativa da literatura na qual utilizou-se as bases de  dados PubMed, BVS (Biblioteca Virtual em Saúde), LILACS, e SciELO. Como critérios de inclusão estavam os artigos publicados na íntegra, relatos de caso clínico, revisões sistemáticas e de meta-análise publicados nos últimos 10 anos,  disponível nos idiomas português ou inglês, que abordassem a temática. Os critérios de exclusão foram: resumos, anais, editoriais, cartas ao editor, reflexão, duplicidade, artigos com detalhamento incompleto. O cisto dentígero é o tipo mais comum dos cistos odontogênicos de desenvolvimento e o segundo mais frequente entre todos que ocorrem nos maxilares, representando cerca de 20% de todos os cistos revestidos por epitélio nos ossos gnáticos. Clinicamente pode estar associado a qualquer dente impactado, porém ele envolve com mais frequência os terceiros molares inferiores. Acomete pacientes entre 10 a 30 anos de idade, com predileção pelo sexo masculino, sendo na maioria dos casos detectados em exames radiográficos de rotina. O tratamento  baseia-se  nas  técnicas  de descompressão,  marsupialização  e enucleação. O prognóstico para os cistos dentígeros é altamente favorável e não há chance de recorrência após a remoção completa. Assim, a decisão terapêutica deve ser tomada de forma adequada para cada caso, levando em consideração a localização anatômica, extensão clínica, tamanho, idade, remoção do dente não irrompido e possibilidades de acompanhamento.

Este artigo discute a guerra de valores instaurada no âmbito da educação brasileira, situando-a dentro do atual processo de desdemocratização e fascistização da sociedade decorrentes das estratégias de manutenção/expansão da governamentalidade neoliberal. Abordamos a projeção da esfera privada familiar sobre uma esfera pública democrática, a partir da análise da ofensiva antigênero nos domínios da educação. Destacamos movimentos como o Escola sem Partido e a favor da escolarização doméstica, pois refletem essas tensões, enquadrando-se em um contexto mais amplo de erosão democrática e expansão da governamentalidade neoliberal. A compreensão é a de que o protagonismo delegado à instituição familiar é um dos elementos que caracteriza a ascensão de forças antidemocráticas que flertam com o fascismo na contemporaneidade. A educação, nesse escopo, constitui-se em campo de disputa do poder, um microcosmo social que reverbera tanto a potência das resistências como também da domesticidade.

Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Kulagin Artem S.
Published: December 2024

The first part of the article provides a brief overview of Soviet criticism in relation to the Anglo-American literary neo-avant-garde from the 1960s until the end of the USSR, first of all, articles collected in a book “Neo-Avant-garde movements in foreign literature 1950-60” published by IWL RAS. Also, the reasons why the neo-avantgarde poetry was not translated and not reviewed in the Soviet period are analyzed. Separately, the article describes the existing literary connections between the neoavant- garde poets of the USA and the USSR, as well as the reverse reception of Soviet poetry and life in the USSR, recorded by American poets during trips to the Soviet Union, in particular, the travelogue book “Leningrad”. Attention is paid to the modern reinterpretation of Soviet-American literary contacts, a review of published and upcoming thematic literature. The second part of the article is devoted to the reception of Soviet literary neo-avant-garde movements by their English-speaking counterparts. The review of publications of Soviet neo-avant-garde poetry in English-speaking countries is carried out: bilingual anthologies by G. Reavy, O. Carlisle, S. Massie and P. France, the almanach “Apollo-77” and “The Blue Lagoon Anthology of Modern Russian Poetry”, collections of poems by V. Ufliand and G. Aygi. The activities of anthology compilers, both individuals and publishers, such as “Ardis press”, are also highlighted separately. The critical reviews, opinions of the compilers and translators on key areas and personalities, contacts and cases of creative interaction between the authors, for example, between G. Aygi and E. Morgan, are mentioned. On the base of these facts a summary of the processes of reception is made and a conclusion on the role of neo-avant-garde poetry in the history of the USSR is carried out.

In Uzbekistan, the main food product is bread, which is produced in various forms from local and imported wheat. Most of it is not studied by microelement analysis. The objective of this study is to quantify trace elements in locally produced wheat from various cultivated regions of Uzbekistan. Four different varieties of wheat are cultivated in Sirdarya, Tashkent region, Kashkadarya and Fergana were selected for analysis. Next, a comparative analysis of the elemental composition like iron, zinc, potassium, calcium etc., in the selected samples were studied. To carry out the above aims, an innovative research method was chosen, which is called improved instrumental neutron activation analysis. This method differs from others in its high accuracy in determining trace elements and its multi-element nature. Using this method, we can understand how insufficient nutrients are in baked goods made from wheat grain grown in Uzbekistan. Based on the results of the study, it can be recommended to enrich the soil with fertilizers high in iron and zinc. As a result, in turn, will have a positive effect on the health of the population, since today there is a shortage of the above listed elements. It was also revealed that the concentration of potassium and calcium in wheat cultivated in Uzbekistan is in a high state than other elements. Using the chosen method, two toxic elements were determined and according to the analysis for toxic elements, all four samples are recommended for consumption, as they do not exceed the permissible level for food safety.

Cancer is highly complex, including cross-talks between signalling pathways and multiple genes. Fortunately, successful anti-cancer drugs, such as cisplatin, are promising to treat cancer. Despite its clinical success, cisplatin presents several issues, including neurotoxicity, ototoxicity, nephrotoxicity, and drug resistance. New supramolecular drug delivery systems can fix these problems with the effective cancer drug cisplatin. This research aims to optimise novel supramolecular drug delivery systems—metallacage (M2L4 (M = metal, L = ligand)—that can be used to encapsulate cisplatin to protect it from metabolism. Specifically, we investigated the shape and stability of ten metallacages using different metals: Pt2+, Pd2+, Ni2+, Cu2+ and Au3+ using Density Functional Theory (DFT) methods to encapsulate one or two cisplatin molecules. Therefore, we utilised WebMo to run PBE0 and Hartree Fock theories, using LanL2DZ as a basis set. The results demonstrate that PBE0/LanL2DZ is the best method to describe the cages. The results show that Endo-N Ni2L4and Endo-N Cu2L4cages are the best ways to encapsulate cisplatins one and two. Endo-C Pt2L4and Endo-C Au2L4, on the other hand, are the least suitable systems for encapsulating cisplatins. Furthermore, Endo-C cages are farther from ground-state energy because they are higherthan Endo-N cages. Therefore,Endo-N cages are superior to Endo-C cages for the encapsulation of cisplatin.

Kapal laut saat ini menjadi alat transportasi yang sangat penting. Bila terjadi kecelakaan di laut maka diperlukan rompi pelampung (life jacket). Rompi pelampung yang ergonomis dapat membuat rasa aman dan nyaman. Rompi pelampung dibuat dari bahan yang ringan dan mudah terapung. Pergantian bahan apung dari styrofoam ke neoprene adalah untuk membuat rompi pelampung yang ergonomis. Neoprene adalah material yang dapat digunakan sebagai alternatif pengganti gabus sintetis (styrofoam). Neoprene adalah bahan yang memiliki rapat massa yang lebih kecil dari styrofoam. Permasalahan yang timbul dari penggunaan bahan apung yang berbeda ini, mengakibatkan perbedaan daya apung antara material styrofoam dengan neoprene pada rompi pelampung serta efisiensinya. Pengujian dilakukan dengan memberikan pembebanan pada kedua jenis bahan tersebut. Tujuan penelitian adalah mengetahui apakah material neoprenedapat digunakan sebagai pelapis pada rompi pelampung yang ergonomis.,dan meneliti apakah daya apung neoprene lebih baik dari styrofoam. Neoprene SBR digunakan dari Dengyu. Pengujian berat jenis dan daya apung.menggunakan prinsip Archimedes Hasil penelitian memperlihatkan bahwa neoprene dapat digunakan sebagai pelapis bagian dalam rompi pelampung karena mempunyai berat jenis lebih besar dari air laut, material tidak kaku, mempunyai struktur sel tertutup, tahan api, dan mempunyai kemampuan menahan berat dengan efisiensi 9,56 %. Sehingga mempunyai keunggulan nyaman dan aman.

Permasalahan utama UKM kopi Lampung adalah rantai produksinya panjang, mesin atau peralatan pengolahannya masih konvensional dan tidak ramah lingkungan. Akibatnya, produk kopi yang dihasilkan berkualitas rendah, yaitu biji kopi memiliki kadar air hanya 18%, banyak pecah, tidak bersih dan tidak seragam. Juga energi fosil dan bahan bakar kayu dominan digunakan dalam lini produksi kopi sehingga tidak ramah lingkungan. Konsep produksi bersih dan sistem terpadu pengolahan kopi Lampung diterapkan, guna menjadikan industri kopi Lampung sebagai penghasil produk kopi berkualitas dan berdaya saing tinggi, serta ramah lingkungan. Penerapan konsep ini dibagi menjadi tiga tahap, yaitu pertama membuat model sistem produksi kopi. Tahap kedua menerapkan model ke dalam lini pengolahan kopi. Tahap terakhir mengevaluasi model yang telah diterapkan melalui penelitian untuk menyempurnakan model sistem produksi kopi. Sistem produksikopi Lampung telah diterapkan dan diperoleh hasil yaitu biji kopi dapat dikeringkan hingga kadar air 12,5% dengan waktu pengeringan sekitar 30 jam dan biji kopi yang dikupas tidak pecah. Biji kopi yang dihasilkan berukuran seragam dan bersih. Selain itu, limbah kopi dapat diubah menjadi energi panas melalui reaktor gasifikasi, yang suhunya sekitar 500°C dan alirannya terus menerus, sehingga dapat digunakan untuk mengeringkan dan memanggang biji kopi. Hasil yang diperoleh menunjukkan adanya peningkatan kualitas biji kopi sehingga UKM kopi diharapkan memiliki posisi tawar dan daya saing yang lebih baik dalam perdagangan kopi guna meningkatkan perekonomiannya. Selain itu, substitusi bahan bakar fosil dan kayu bakar menjadi energi panas yang berasal dari gasifikasi limbah kopi berpotensi menurunkan biaya produksi dan menciptakan kelestarian lingkungan.
