Authors: Ascar Priscila Cardoso Braz , Leão Jovelino Quintino de Souza , Carvalho Maria Fernanda Camargo de , Nogueira Paulo Cesar Koch
Published: February 2024

O número de transplantes renais em crianças pequenas (bebês ou com menos de 15 kg) aumentou devido à melhoria do diagnóstico pré-natal, ao encaminhamento mais precoce para centros especializados e aos avanços no tratamento de pacientes com insuficiência renal. A maioria desses pacientes tem anomalias congênitas do rim e do trato urinário, que precisam ser corrigidas antes do transplante. Para enfrentar esse desafio, a presença de um urologista pediátrico trabalhando em conjunto com uma equipe multidisciplinar experiente é fundamental. Este estudo fornece uma revisão narrativa compilando detalhes sobre o manejo urológico do trato urinário de pacientes de baixo peso com doença renal crônica e anomalias congênitas do rim e do trato urinário (CAKUT) encaminhados para transplante renal (TR). Objetivos: Realizar uma revisão narrativa sobre a correção urológica em crianças pequenas antes do TR. Métodos: Foram revisados artigos publicados em língua inglesa nos últimos 20 anos. As palavras-chave consideradas para a pesquisa e seleção de artigos foram TR pediátrico ou transplante de rins e crianças, ou crianças pequenas, ou lactentes pequenos, ou crianças jovens, ou lactentes jovens e reconstrução do trato urinário e CAKUT. Alguns artigos referenciados para elucidar os aspectos urológicos da revisão também foram incluídos.

This study examines the anti-corruption movement's effect on state officials' asset reporting in Indonesia and China. The purpose of this study is to explore the impact of asset reporting on the level of corruption in Indonesia and compare the impact of asset disclosure on the level of corruption in China. The method used in this study is the normative juridical method. In Indonesia, we found that the reporting of assets official assets anti-corruption movement shows that despite the obligation to make asset reports for state officials, the level of corruption in Indonesia is still high. In China, there is a decrease in corruption in asset disclosure, an essential instrument of wealth transparency, preventing conflicts of interest, and upholding ethical standards in both the public and private spheres. Asset disclosure serves as a deterrent to corruption, maintains public trust, and ensures that individuals in positions of responsibility act in the best interests of the public or stakeholders they serve, statistically decreasing corruption rates in China. This study provides evidence of anti-corruption benefits from an asset reporting perspective, which can be helpful for governments seeking to improve anti-corruption innovation.
A racionalidade político-administrativa como potencial ao processo regulatório
Authors: Mendes Flavine Meghy Metne , Pinto Júnior Helder Queiroz
Published: February 2024

Não é de hoje que se reconhece que os sistemas reguladores são constituídos por elementos interconectados que devem funcionar no processo de coordenação, direção e equilíbrio de interações entre sociedade e Estado. Na ambiência regulatória, as normas regulatórias devem guardar relação de coerência entre si e plena compatibilidade com os demais preceitos que informam o ordenamento jurídico brasileiro. Uma estrutura normativa que se repute débil com os citados padrões facilita a ocorrência de falhas no alcance dos objetivos da governança regulatória, sem contar o desperdício de tempo e recursos. Nestes moldes, o presente artigo investiga os vetores e requisitos de legitimidade do processo regulatório normativo, sob a premissa de que as agências reguladoras guardam íntima relação com a evolução do Estado e da sociedade, que subentende o compromisso de prover serviços de qualidade. Sob domínios cada vez mais complexos e influenciados pelos avanços científicos e tecnológicos, ganha destaque o compromisso coletivo no panejamento, participação e transparência na construção de decisões regulatórias responsivas. No rol dos benefícios que se queira considerar, o processo participativo retroalimenta a capacidade de resposta estatal, estimulando acima de tudo o equilíbrio regulatório. Do ponto de vista metodológico, desenvolveu-se estudo descritivo, cujas fontes são constituídas por estudos desenvolvidos primacialmente no âmbito internacional. A partir das ideias desenvolvidas, pretende-se propiciar subsídios, em linha com o princípio da segurança jurídica, no caminho de preparação, direção e equilíbrio que se espera entre Estado e sociedade no contexto da pós-modernidade, que devem ser observados pelas agências reguladoras no processo de edição das normas regulatórias.
Pedagogia universitária: um ensaio epistemológico
Authors: Rabelo Roberto Araújo da Silva Vasques
Published: February 2024

O artigo discute a pedagogia universitária, considerando-a esforço epistemológico sobre a práxis educativa da e na educação superior.  O estudo parte de pressupostos teóricos que defendem a pedagogia como ciência da educação e identificam a universidade como instituição social relevante para o desenvolvimento humano. No Brasil, o ambiente universitário foi historicamente marcado pelo elitismo e por práticas educativas tradicionais, tecnicistas e conservadoras. Atualmente, ressaltam-se a mercantilização indiscriminada e a ampliação do acesso via aumento de cursos de graduação à distância. Tais aspectos dificultam a consolidação da pedagogia universitária no país, pois tendem a posicionar as práticas educacionais como atos para a reprodução da ordem social, assim como facilitar a oferta de formação aligeirada e acrítica. Desse modo, este estudo busca auxiliar na construção de respostas às seguintes questões: o que configura epistemologicamente a pedagogia universitária? E quais as potencialidades progressistas e emancipatórias dessa pedagogia? O texto adota caráter ensaístico, valendo-se de hermenêutica sociológica e filosófica fundamentada na Teoria Crítica de Zygmunt Bauman. Nesse sentido o artigo tem como objetivos explorar e analisar os fundamentos epistemológicos que sustentam práticas pedagógicas na educação superior, tendo em vista a dinâmica entre docentes, discentes, conteúdos curriculares e condições sócio-históricas contemporâneas. Ao estudar epistemologicamente a pedagogia universitária, o texto visa auxiliar a construção de compreensões que identificam esse subcampo como práxis crítica da e na educação superior. Assim, o artigo pretende contribuir com avanços no entendimento sobre pedagogia universitária e destacar sua relevância para a formação de justiça social e cognitiva. Finalmente, o estudo defende a pedagogia universitária como ciência da educação superior dotada de potenciais formativos emancipatórios.

Published: February 2024

The use of particleboard has currently expanded, mainly due to the need for wood conservation. Therefore, this study aimed to evaluate the physical-mechanical properties and temperature variation of particleboards, by analyzing the addition of 1% ZnO nanoparticles in polyurethane resin based on castor oil, in comparison to particleboard without nanoparticles. The polyurethane resin offers enhanced performance in water contact and is formaldehyde-free, thus making it more sustainable. The properties assessed included density, moisture content, thickness swelling, water absorption, modulus of elasticity, and rupture modulus in static bending, following the specifications of Brazilian (ABNT NBR 14810: 2013), European (EN 312:2010), and American (ANSI 208:2018) standards. Additionally, the analysis included an assessment of pressing temperature variation. The results indicate that the addition of ZnO nanoparticles improved the properties of the particleboard, particularly in wet conditions, which are typically challenging for wood products. These enhancements can be attributed to the improved temperature variation facilitated by the nanoparticles, as observed through temperature analysis. Thus, the incorporation of nanoparticles contributed to the advantages of using a more sustainable resin, leading to advancements in the timber industry.

Road Transportation is the major mode of transportation and is recognized as a significant contributor to the socio-economic development in many low-and-middle-income countries like in Bangladesh. In Bangladesh, this transport system is now responsible for carrying about 70% of passengers and 60% of freights and increasing the share of modalities day by day with the development of road transport systems. The responsibility for the improvement and maintenance of the total road network of the country is assigned mainly to the Roads and Highways Department (RHD) and the Local Government Engineering Department (LGED). But the road network belongs to LGED termed as “Rural Road” which is about 94% of the total road length and in the meantime, more than 40% is improved by mainly flexible pavements. However, the state of road traffic safety on many improved rural roads is poor due to narrow carriageways and shoulders along with roadside hazards. On the other hand, the overall road traffic safety in Bangladesh is poor compared to the developed and motorized countries. However, according to the police report, about 4000 people die and another 5000 people become injured by road traffic crashes in each year in Bangladesh but the World Health Organization estimates the fatalities are more than 25,000. However, Bangladesh has committed to achieving the targets 3.6 and 11.2 of the Sustainable Development Goals (SDG) assigned by the United Nations (UN) in 2015 concerning the improvement of road traffic safety by halving 50% of fatalities by 2030. Therefore, the achievement of the above two targets depends on the improvement of road traffic safety on highways as well as rural roads. This research highlights the barriers to improving the safety of rural roads to achieve the above two targets by 2030.

Type 2 diabetes mellitus (T2DM) is a metabolic disorder with multiple causes. The prevalence of T2DM is on the rise, however, on the African continent, nearly 70% of all T2DM cases go undiagnosed. T2DM places a great burden on the already stretched healthcare systems. Current tests do not provide predictive measures in terms of the possible onset of the disease. Biomarker and gene analysis have been used to predict the onset of the disease, but this has seen very limited use in the African population groups. Identification of variances in biomarkers and subsequent genetic aberrations at early diagnosis could enable clinical focus on patients more likely to develop insulin resistance. The aim of the study was to compare T2DM-associated biomarker levels between T2DM patients and non-T2DM participants and identify genetic variances in single nucleotide polymorphisms (SNPs) associated with the biomarkers. Two cohorts (n = 78) were screened for associated biomarkers using a commercially available enzyme-linked immunosorbent assay (ELISA) kit. The results of this analysis were used to select SNPs in genes associated with the screened biomarkers. The molecular genotyping was completed using quantitative polymerase chain reaction (qPCR) assays. The biomarker analysis revealed significant statistical differences between four of the ten screened biomarkers: Glucose-dependent insulinotropic polypeptide (GIP) (p = 0.0004), resistin (p = 0.0398), visfatin (p = 0.0009), and glucagon (p = 0.0034). The SNPs selected for molecular genotyping were rs6235 in proprotein convertase subtilisin/kexin type 1 (PCSK1) and rs2208203 in proprotein convertase subtilisin/kexin type 2 (PCSK2). Both these genes are involved in the biosynthesis of various biomarkers that were screened. The results from the molecular genotyping failed to show any significant difference between the control and T2DM case groups. While some biomarkers were shown to have significant statistical differences between the two study cohorts, more work needs to be conducted to understand the role of each biomarker in T2DM.

Poverty is an emerging problem that most economies are facing today. The study is aimed at exploring research conducted on measuring non-monetary poverty via machine learning. Non-monetary poverty is identified through the following factors: demographics, population, distribution of income, climate, culture, ethnics, and availability of natural and artificial resources. Today, one of the most important aspects of non-monetary poverty measurement is using machine learning for multiple data points other than wealth or income to assess the quality of life of an individual or community. The socioeconomic factors that contribute poverty in emerging nations have also been found using machine learning algorithms. To achieve our goal neutrosophic model and machine learning algorithms were applied. Neutrosophic model used for reviewing the poverty indicators along with ML algorithms. While exploring the utility of machine learning in our study to measure poverty we will find the answers for the following questions: (1) Why it is important to take into consideration of non-monetary approaches while calculating poverty rate? (2) Which machine learning algorithms were used in poverty measurement? (3) What is the future scope of machine learning applications in poverty prediction? In finding answers for those questions, we have analyzed overall 10 papers which were collected according to exclusion and inclusion criteria and the purpose of the selection according to the content of the paper. During the survey it was found out that machine learning gives sophisticated data for identifying non-monetary reasons of poverty and this survey is first that uses machine learning to non-monetary poverty factors.

Published: February 2024

Введение. В статье рассмотрено влияние потока инвестиций в основной капитал российских предприятий, формирующегося из различных источников и направляемого в различные сферы производственной деятельности, на динамику валового внутреннего продукта. Материалы и методы. В работе предложена классификация источников финансирования инвестиций в основной капитал, выполненная на основе проведенного обзора зарубежной литературы. Построенная авторегрессионная модель позволила выявить статистические связи между динамикой ВВП и инвестициями, приходящими в реальный сектор российской экономики из различных источников. Результаты исследования. В работе приводятся результаты тестирования декомпозиции валовых инвестиций в основной капитал по источникам и направлениям финансирования на чувствительность к инфляционной динамике. Обсуждение и заключения. В статье сделан вывод о том, что анализируемые инвестиционные потоки не оказывают статистически значимого влияния на уровень потребительских цен в стране. Предлагается создать на макроуровне условия для снижения ключевой ставки ЦБ РФ с целью резкого возрастания объѐмов инвестирования банковских средств в обновление основных фондов российских предприятий. При этом не стоит опасаться всплеска инфляции, так как результаты статистических расчетов показывают, что современная российская инфляция имеет немонетарную природу.

Introduction. The article examines the impact of investments in fixed capital of Russian enterprises on the dynamics of gross domestic product. However, the authors analyze not gross investments, but their components by sources of financing and areas of investment. Materials and methods. The paper proposes a classification of sources of financing investments in fixed capital, based on a review of foreign literature. The constructed autoregressive model made it possible to identify statistical connections between the dynamics of GDP and investments coming into the real sector of the Russian economy from various sources. Results. The paper presents the results of testing the decomposition of gross investments in fixed assets by sources and directions of financing for sensitivity to inflation dynamics. Discussion and conclusions. The article concludes that the analyzed investment flows do not have a statistical impact on the level of consumer prices in the country. The article proposes to create at the macro level to reduce the key rate of the Central Bank of the Russian Federation in order to sharply increase the volume of investment of bank funds in the renewal of fixed assets of Russian enterprises. At the same time, there is no need to fear a surge in inflation, since the results of statistical calculations show that modern Russian inflation is of a non-monetary nature.
Acoustics of Emphatics and Uvulars in Bedouin Hijazi Arabic
Authors: Solami Majed Al
Published: February 2024

The current study examines the effects of emphatics /ðˤ sˤ tˤ/ and uvulars /ʁ χ/ on following vowels in Bedouin Hijazi Arabic. The main goal is to observe F1 and F2 of vowels /i æ u/ next to the aforementioned sounds. The outcome of this study shows that F1 and F2 values next to emphatics and uvulars are reliable acoustic correlates. Emphatics and uvulars next to vowels increase F1 values, a pattern not noticeable in vowels next to plain sounds /ð s t/. Both groups also show lower F2 values compared to plain coronals. The size of F2 decrease, however, is lower in vowels following emphatics than vowels following uvulars. Differences in F2 values between these sound groups suggest differences in their articulatory mechanisms.

Authors: Klawson Ben , Buchowski Jacob M. , Punyarat Prachya , Singleton Quante , Feger Mark , Theologis Alekos A.
Published: February 2024

Objective:

To compare adults with isthmic L5-S1 spondylolisthesis who were treated with three different surgical techniques: PS-only, TS, and transforaminal lumbar interbody fusion/posterior lumbar interbody fusion (TLIF/PLIF).

Methods:

This is a retrospective analysis of adults with L5-S1 isthmic spondylolisthesis (grade ≥2) who underwent primary all-posterior operations with pedicle screws. Patients were excluded if they had <1 year follow-up, anterior approaches, and trans-sacral fibular grafts. Patient demographics and surgical, radiographic, and clinical data were compared between groups based on the method of anterior column support: none (PS-only), TS, and TLIF/PLIF.

Results:

Sixty patients met inclusion criteria (male patients 21, female patients 39, average age 47 ± 15 years, PS-only 16; TS 20; TLIF/PLIF 24). TS patients more commonly had high-grade slips and markedly greater slip percentage, lumbosacral kyphosis, and pelvic incidence. The three groups were similar for smoking status, visual analog scores/Oswestry Disability Index scores (VAS/ODI), surgical data, and average follow-up (40.1 ± 31.2 months). All groups had similarly notable improvements in Meyerding grade and lumbosacral angle. Slip reduction percentage was similar between groups. While there was a markedly higher overall complication rate for PS-only constructs, all groups had similarly notable improvements in ODI and VAS back scores.

Conclusions:

All-posterior techniques for L5-S1 isthmic spondylolisthesis resulted in excellent improvement in preoperative symptoms and HRQoL scores and similar radiographic alignment. Trans-sacral screws were more commonly used for high-grade slips. The use of anterior column support resulted in fewer overall complications than posterior-only instrumentation.
«Я очень сильно маму люблю»: потребности и препятствия в межпоколенном диалоге детей и родителей
Authors: Иванова Анна , Россинская Анастасия
Published: February 2024

В статье представлены результаты исследования особенностей детско-родительского общения, которое проводилось с целью выявления проблем в коммуникации, препятствующих нормальному межпоколенному диалогу между родителями и их взрослыми детьми (18–32 года). Сбор материала осуществлялся посредством глубинного феноменологического интервью, посвященного общению с родителями в подростковом и взрослом возрасте. Качественный анализ интервью методом конденсации смыслов позволил выделить три ключевых категории смыслов: потребности детей, препятствия для их реализации и стратегии, позволяющие преодолеть их. Было установлено, что потребность детей к сепарации по достижении подросткового и взрослого возраста противоположена потребности родителей в удержании контроля над ребенком. При этом у взрослых детей продолжает сохраняться потребность во внимании со стороны родителей, которая часто не реализуется вследствие недостаточно развитой коммуникативной компетенции у родителей и отсутствия интереса родителей к ребенку. В центре этого конфликта потребностей фиксируется феномен отсутствия общего языка для общения между поколениями в семье, что усугубляется принадлежностью родителей к другому поколению не только в возрастном, но и в историческом аспекте. Отдельную проблему в межпоколенном диалоге составляет отстраненный характер общения с отцом. Было также выяснено, что для преодоления препятствий к нормальному общению дети вырабатывают следующие коммуникативные стратегии: стратегии самозащиты, стратегии заботы о родителях и стратегии установления контакта. В заключение обсуждается необходимость создания возможностей для безопасного общения детей и родителей как в городских пространствах и «третьих местах», так и в формате отдельных событий.

This study assessed the ecological consequences of heavy metal contamination in soil induced by spent engine oil (SEO) and palm oil mill effluents (POME) in Ebonyi State, Nigeria. Concentrations of zinc, nickel, mercury, manganese, lead, iron, copper, chromium, and cadmium were analyzed across contaminated and uncontaminated sites. The research, conducted at Ebonyi State University’s Presco Campus, employed rigorous sampling and analytical methods. Results revealed that soil contaminated with spent engine oil effluent exhibited elevated mean concentrations of zinc, nickel, manganese, lead, iron, copper, chromium, and cadmium compared to the palm oil mill effluent and control sites. Conversely, mercury concentrations were higher in soil contaminated with palm oil mill effluent. Comparative analyses highlighted unique dynamics, such as lead concentrations being highest at the control site, challenging general trends observed for other metals. Importantly, none of the mean concentrations exceeded the WHO acceptable limits at the time of the study, indicating compliance with internationally recognized safety thresholds. The findings underscore the need for tailored environmental management strategies, considering specific contaminants associated with each effluent type. Continuous monitoring is crucial to ensure sustained adherence to safety standards and prevent potential future exceedances. This study contributes a valuable understanding of the nuanced ecological impact of industrial effluents on soil quality in Nigeria, emphasizing the importance of sustainable practices for environmental protection.
Allele and Phenotype Frequencies of CYP2D6 In The Turkish Population
Authors: Polat Safa , r Muhammet , am Fethi
Published: February 2024

Aim: Cytochrome P450 is a hepatic enzyme system responsible for drug metabolism comprising different iso-enzymes. CYP2D6 enzyme, which composes 2-4% of all cytochrome enzymes, is responsible for 25% of the metabolisms of the drugs used in clinics. The genetic polymorphisms of this enzyme can change the efficiency and toxicity of the drugs used. In this study, the retrospective evaluation of CYP2D6 gene polymorphisms that influence enzyme activity in the Turkish population is targeted.
Materials and Methods: From the 192 patients sent from psychiatry, medical genetics and neurology polyclinics to our laboratory, by the methods of Multiplex Polymerase Chain Reaction (PCR) and Multiplex Allele Specific Primer Extension (ASPE), CYP2D6 enzyme gene polymorphisms were determined.
Results: Of all the cases, 82,29% were determined as extensive, 12,5% as intermediate, 2,08% as poor and 3,13% as ultra-rapid metabolizers. In our population, the most frequent alleles were *1 (37,63%), *2 (24,75%), *41 (15,15%), *4 (9,85%) and *10 (4,29%), respectively.
Conclusion: In the current examined population, compared to the previous studies conducted on Turkish society, it was determined that the percentage of extensive metabolizers was higher while the percentages of poor metabolizers and ultra-rapid metabolizers were lower. In addition, *41 allele that follows the decrease in enzyme function was detected as the most frequent allele in this study. The fact that the percentage of the cases in which changes were observed was 17,1% will help determine the CYP2D6 gene mutations in the pre-treatment cases.
A Comparison of the Success of Intubation Using C-MAC D-Blade and McGrath MAC X3 Blade Videolaryngoscopes during Double Lumen Tube Insertion in One-Lung Ventilation: A Prospective, Randomized Clinical Trial
Authors: Erturk Kas , zkan Ahmet , Akba Sedat , Karaaslan Erol , Durmu Mahmut
Published: February 2024

Objective: To compare the effects of C-MAC D-Blade and McGrath MAC X3 Blade videolaryngoscopes (VLs) during double lumen tube (DLT) insertion in one-lung ventilation (OLV) in patients who underwent chest surgery in terms of intubation durations, hemodynamic responses, and intubation-induced complications.
Materials and methods: Fifty patients aged 18−65 years who were scheduled for OLV were included in this study. The patients were divided randomly into two groups: a Storz C-MAC D-Blade VL group (C-MAC group, n = 25) and a McGrath MAC X3 Blade VL group (McGrath group, n = 25). The results of a preoperative airway assessment, number of intubation attempts and incidence of success at the first attempt, glottic view times, intubation times, Cormack−Lehane scores, percentage of glottic opening (POGO) scores, ease of intubation, comorbidities, hemodynamic responses, and adverse intubation-related events were recorded.
Results: The demographic characteristics and comorbidities of both groups were similar. The intubation characteristics of both groups were similar in terms of Cormack−Lehane scores, thyromental and intergingival distances, and POGO scores. In the C-MAC group, the glottic view times (p = 0.001) and intubation times (p = 0.001) were significantly shorter than those in the McGrath group. As shown by ease of intubation scores, ease of intubation in the C-MAC group was significantly better than that in the McGrath group (p = 0.001). All the patients in the C-MAC group were intubated at the first attempt, without a statistically significant difference. The two groups were similar with respect to intubation-related complications and hemodynamic responses (mean arterial pressure [MAP] and heart rate [HR]).
Conclusion: We conclude that the C-MAC D-Blade VL is more beneficial for airway management due to shorter glottic view and intubation times, high success rates at the first attempt, and ease of intubation in patients intubated with a DLT in OLV.

Methods: A comprehensive search of Ovid MEDLINE, Web of Science, PubMed, and Cochrane CENTRAL was conducted. The primary efficacy outcomes included changes in hemoglobin (Hb) levels during follow-up and at week 16. Inverse variance random effects models were used for main analysis. The overall risk of bias (RoB) was assessed using the Cochrane RoB2 tool.
Results: Six randomized controlled trials (RCTs) involving 999 patients were included. The meta-analysis for Hb change during follow-up revealed a mean difference (MD) of 0.09 (95% CI, -0.49 to 0.67), p=0.071, with an I² of 81% whereas Hb change at week 16 showed an MD of 0.12 (95% CI, -0.40 to 0.64), p=0.65 with an I² of 85%. Notably, changes in hepcidin levels during follow-up (MD -16.55, 95% CI -29.54 to -3.56) favored molidustat but not changes in total iron binding capacity at week 16 (MD 2.89, 95% CI 1.74 to 4.04). However, the impact of molidustat on transferrin saturation, iron levels, and ferritin levels showed comparable results. Regarding safety outcomes, no significant differences were observed in treatment emergent adverse events (TEAE) leading to death, patients with ≥1 major adverse cardiovascular event (MACE), hyperkalemia, any TEAE, and any serious TEAE. The risk of CKD worsening was increased with molidustat (MD 1.79, 95% CI 1.03 to 3.10). Subgroup analyses for primary outcomes were consistent with main analyses. RoB for Hb change was found as high/some concerns in 5/1 RCTs, respectively.
Conclusion: Molidustat exhibited noninferiority to ESAs in managing anemia in CKD patients. However, a concerning finding was the increased risk of CKD worsening associated with molidustat use. Well-designed RCTs are essential to enhance our understanding of molidustat's in CKD-related anemia.

Aim:This study aimed to evaluate the effects of orchidectomy, Burdizzo castration, and in-situ spermatic cord ligation on interleukin 6 (IL-6) responses in red Sokoto bucks.
Methods:Sixteen (16) Sokoto red bucks (6 months to 1 year old and 11-12 kg body weight) were randomly assigned and divided into 4 groups (A, B, C, and D) each containing 4 bucks. Group A were castrated using Burdizzo), B in-situ spermatic cord ligation, and C orchidectomy while group D (control) was not castrated. Blood was collected pre-castration, at immediate, 4, 8, 12, 16, 20, 24-, 32-, 48- and 72-hours post-castration (hpc) into plain labeled tubes, serum harvested and analyzed for IL-6 levels.
Results:Results revealed significant (p < 0.05) increased IL-6 levels in groups A, B, and C from 4 hpc, reaching peak levels at 20 hpc with the highest recorded in group C followed by group B and then group A.
Conclusion:In conclusion, orchidectomy, Burdizzo castration, and in-situ spermatic cord ligation elicited IL-6 responses but the response was highest with orchidectomy followed by in-situ spermatic cord ligation,then Burdizzo castration. This indicates that these castration methods increased inflammation, thus suggesting that IL-6 can be used to determine inflammatory responses for bucks after castration. This is the first study to demonstrate a relationship between orchidectomy, Burdizzo castration in-situ spermatic cord ligation, and serum IL-6 levels in the red Sokoto bucks

Design of Mutiple Signal Generators based on DDS
Authors: Li Zhiyu , Meng Yue
Published: February 2024

The hardware circuit of the signal generator mainly includes the main control module, DDS module, Voltage-Controlled Gain Amplifier (VCGA) module, keypad module, and LCD display module. The main control module is based on the STM32F103C8T6 as the core controller, and the signal processing section employs the low-power, programmable AD9834 DDS device. The VCGA module utilizes the AD8367 module, providing a controllable 32dB gain range to offer a 20mV/dB output. The waveform voltage amplitude can be adjusted by manipulating the potentiometer on the module and fed back to the oscilloscope. Experimental results demonstrate that the signal generator can produce square waves, triangular waves, sine waves, and sweep frequency waves with stable output waveforms and high resolution. Specifically, the sine wave and triangular wave can be generated within the frequency range of 1kHz to 200KHz, the square wave within the range of 75kHz to 200kHz, and the sweep frequency wave with a sweeping range from 1kHz to 100kHz.
Effects of Ecological Restoration on Degraded Riparian Plant Communities
Authors: Jiang Xuexia , Qin Jiaofen
Published: February 2024

Riparian areas are the transitional zones between terrestrial and aquatic ecosystems. Riparian have been experienced serious river channelization, riparian hardening and other anthropogenic activities. These disturbances result in degradation of ecological function and reduction of biodiversity of riparian ecosystems. There are many ecological engineering to restore riparian ecosystems in China. The research results of this article indicate that species richness and the Shannon-Wiener diversity index were: restored sites > natural sites > channelized sites, and biomass of natural sites was significantly lower than that of restored and channelized sites. The reason is that river channelization severely changed the composition and structure of plant communities and decreased plant diversity in riparian zone. Practicable ecological restoration measures could effectively reconstruct the plant communities and improved plant diversity in the channelized riparian zones.

Essas transformações acabam por refletir diretamente no vestuário do período, promovendo a extravagância entre os com maior poder aquisitivo. Este artigo objetiva sintetizar o que foi a moda medieval, primeiramente apresentando o contexto histórico, em seguida, analisando por uma perspectiva de gênero binária, é apresentado as principais características da indumentária destes no decorrer do milênio, e por fim expõe-se sobre os tecidos que constituíam as vestes da Idade Média. Para a execução do presente trabalho foram realizadas revisões bibliográficas e imagéticas acerca da moda medieval, os dados adquiridos com base em tais revisões permitiram constatar que as novas tecnologias criadas na era medieval, como o tear horizontal e inovações nas técnicas de tingimento de tecido, proporcionam uma mudança drástica na silhueta dos artigos de vestuário e na gama de possibilidades de produção como um todo.
Consumo y cambio social en España evolución en el equipamiento doméstico (1983-2005)
Authors: Brändle Gaspar
Published: February 2024

Desde la década de los sesenta algunos indicadores socieconómicos permiten hablar de una incipiente sociedad de consumo en España. Desde entonces la evolución social, política y económica en nuestro país ha sido considerable. En este estudio se sostiene la idea de que existe una influencia recíproca entre el consumo y la evolución social. Se tratan de explicar aquí las tendencias de consumo ?en equipamiento doméstico? a partir de diferentes variables sociodemográficas, empleando varios estudios del Centro de Investigaciones Sociológicas publicados a lo largo de los últimos veinticinco años. En líneas generales, se puede concluir que en una sociedad de consumo desarrollada, donde el acceso a los bienes superiores está democratizado, las diferencias van más allá de la típica variable ingresos, para centrarse en aspectos más sutiles, relacionados con los estilos de vida.

La opinión pública catalana frente a la coalición parlamentaria entre PSOE y CiU en la V Legislatura de las Cortes Generales (1993-1996)
Authors: Calvet Crespo Jordi
Published: February 2024

En el presente artículo se analiza la percepción de la coalición parlamentaria entre el PSOE y CIU en la opinión pública catalana. El análisis utiliza una serie de variables explicativas de carácter eminentemente político, como son la identificación con los partidos y la autoubicación ideológica en los ejes de conflicto. Los datos ponen en evidencia que los individuos legitiman la conducta de su formación en las Cortes, bien apoyando el pacto, bien rechazándolo según si aquélla forma parte de la mayoría parlamentaria o de la oposición. Sin embargo, al considerar sólo las posiciones en los ejes izquierda-derecha y nacionalista se observan los matices. El sentimiento nacional es el elemento que decanta la valoración sobre el acuerdo: positivamente si se parte de una postura catalanista, pero negativamente si se trata de una españolista. La influencia de una formación de ámbito no estatal en la gobernabilidad española es el factor que provoca mayor división de actitudes.
