Published: August 2024

En base a la experimentación, en este artículo se van a exponer los métodos por los cuales se ha llevado a cabo una composición, siendo la base de la creación la escala pentatónica de la escala de blues mayor. El interés de esta creación se va a destacar en la forma en la que se van presentando las distintas notas y cómo combinan entre ellas en relación a diferentes sonidos, tesituras varias y distintos instrumentos. La combinación de todos ellos y el uso esporádico de la aleatoriedad, nos va a mostrar las posibilidades de este tipo de escalas y las dificultades que muestran este tipo de composiciones, en relación a su utilización y a las relaciones interválicas y armónicas. Este artículo va a ser el resultado del producto musical de una composición justificada como creación experimental.
Based on experimentation, in this article we are going to expose the methods by which a composition has been carried out, being the basis of the creation the pentatonic scale of the major blues scale. The interest of this creation will be highlighted in the way in which the different notes are presented and how they combine with each other in relation to different sounds, different tessituras and different instruments. The combination of all of them and the sporadic use of randomness, will show us the possibilities of this type of scales and the difficulties that show this type of compositions, in relation to its use and the intervallic and harmonic relations. This article will be the result of the musical product of a composition justified as an experimental creation.

Authors: Ben I.E.  , Enokela O.S.  
Published: August 2024

Abstract: Soil moisture balance from okra (abelmoschus esculentus) field was performed on experimental plot of the Department of Agricultural and Environmental Engineering, Joseph Sanwuan Tarka University Makurdi -Nigeria. Field and laboratory experiments were conducted on four okra cultivars planted and irrigated by drip system at different levels (80% (I1), 60% (I2), 45% (I3), and 15% (I4)) according to the agronomic practices of okra. Decision Support System for agro technology Transfer (DSSAT) model for the Crop Environment Resource Synthesis (CERES) was used to model soil moisture balance by linear regression (multivariate analysis of variance, (MANOVA)) and validated. The soil was sandy loam with high field capacity (FC) at I4 and nearly uniform drainage (D) except for I4.. Runoff (R) decreases from 35.71 for I1 to 0.07 for I4 implying that R, D and change in water storage (∆S) are functions of the amount and duration of irrigation. The models reported an acceptable deviation from the ideal line of the R and ∆S at higher values confirming degree of the correlation between the observed and predicted dataset but experienced difficulties with estimating lower values due to lower magnitudes in irrigation. From the foregoing it is concluded that decreasing water application results in an increase in irrigation and the reverse is also true.

OBJECTIVES: The association between occupational psychosocial factors and mental health has been studied in several systematic reviews. However, few systematic reviews exist that specifically address suicidal ideation. Therefore, this systematic review and meta-analysis aimed to examine the associations between long working hours, shift work, and suicidal ideation.
METHODS: We systematically screened and collected studies published between January 1970 and September 2022 from three electronic databases and Google Scholar. We conducted a meta-analysis using a random-effects model and assessed the risk of bias using a navigation guide. Additionally, the grading of recommendations assessment, development and evaluation (GRADE) approach was used to consider five items, including the risk of bias and publication bias.
RESULTS: Twenty-eight articles were included in this meta-analysis. After adjusting for covariates, the overall odds ratio (OR) for long working hours and shift work were 1.44 [95% confidence interval (CI) 1.26–1.63] and 1.34 (95% CI 1.22–1.47), respectively. Compared with those who worked <40 hours per week, those who worked >55 hours per week had a 1.65 (95% CI 1.37–1.98) higher risk of suicidal ideation, and fixed night shift workers had 1.37 (95% CI 1.03–1.83) higher risk than non-shift workers.
CONCLUSIONS: Evidence has shown associations between long working hours, shift work, and suicidal ideation. Implementing evidence-based interventions to address these risk factors may help prevent the progression of suicidal ideation. However, further studies are critically needed, especially those using standardized exposure definitions and longitudinal data.

Дается характеристика золотоносной конгломератовой толщи, включая ее геолого-структурное положение, литолого-петрографический состав и наложенные метасоматические преобразования. Описываются особенности морфологии и состава аллювиального и рудного золота. Показано, что кроме кластогенного, в конгломератах присутствует серебро и медь, содержащее новообразованное золото, связанное с мезозойской магматической активизацией. Делается вывод об изначальных источниках золота в конгломератах, связанных с диафторезом и альбитизацией в габбро-анортозитах. Предлагается версия прибрежно-морского происхождения кластогенного золота. Рассматриваются перспективы конгломератовой толщи как возможного объекта рудной золотодобычи.
The Nemuysky district of the Khabarovsk Territory is famous for large placer gold and nuggets. The article shows that the main source of gold in alluvium is a conglomerate strata with rounded clastogenic gold, including in the form of pebbles. The characteristics of the gold-bearing conglomerate strata are given, including its geological and structural position, lithological and petrographic composition and superimposed metasomatic alterations. The features of the morphology and composition of alluvial and ore gold are described. It is shown that, in addition to clastogenic gold, the conglomerates contain newly formed gold associated with Mesozoic magmatic activation. A conclusion is made about the original sources of gold in conglomerates associated with diaphthoresis and albitization in gabbro-anorthosites. A version of the coastal-marine origin of clastogenic gold is proposed. The prospects of the conglomerate strata as a possible object of ore gold mining are considered.

Published: August 2024

Surgical miscarriages are a common obstetric issue with potential long-term effects on subsequent pregnancies. Objective: To evaluate the association between previous surgical miscarriages and the risk of preterm birth in later pregnancies. Methods: This descriptive cross-sectional study was conducted at the Department of Obstetrics & Gynaecology, Mekran Medical College (MMC), Turbat, from November 2023 to April 2024. Data collected included age at second pregnancy, BMI, socioeconomic status, smoking status, and medical conditions such as hypertension and diabetes. Collected data were processed and analyzed using IBM SPSS, version 27.0. Results: The study included 230 patients with a history of miscarriage. Participants with ≥ 3 previous miscarriages had significantly higher odds of all-cause preterm birth (OR = 8.19, p = 0.050), spontaneous preterm birth (OR = 6.38, p = 0.005), and induced preterm birth (OR = 4.64, p < 0.001) compared to those with 1 previous miscarriage. After adjustment, those with ≥ 3 previous miscarriages had higher odds of all-cause (OR = 4.92, p < 0.001) and spontaneous preterm birth (OR = 5.79, p = 0.005), but not induced preterm birth (OR = 5.63, p = 0.050). Conclusions: Our study results revealed a significant association between a history of previous surgical miscarriages and the probability of preterm births in subsequent pregnancies. These findings underscore the need for clinical monitoring and interventions for women with a history of surgical miscarriages
Studies on the association between maternal cardiometabolic health and the oral microbiota of mother-child pairs.
Authors:   , Maia Azevedo Maria João 
Published: August 2024

A reciprocal interaction has been proposed to exist between cardiometabolic risk factors (CRFs) and the oral microbiota. However, the role of maternal CRFs on the oral microbiota in early life is not well understood. We hypothesized that the cardiometabolic background of the mother might affect the oral microbial composition of the child. Therefore, the main aim of this thesis was to evaluate the role of maternal CRFs on the oral bacteriome and mycobiome of mother-child dyads during pregnancy and early life. In order to achieve our goal, a cohort of women/mother-child pairs was followed from the third trimester of pregnancy, one month after delivery, and 6 months after delivery.
In summary, we can conclude that:
i)	The oral bacteriome but not the mycobiome of women in our study population is associated with CRFs (including arterial hypertension). Some of the implicated genera are involved in the nitrate-nitrite-nitric oxide pathway, supporting the current evidence that oral bacteria may be linked to cardiometabolic health. Women with AH, one of the CRFs, presented higher levels of oral inflammation detected via oral proteome and oral health assessments. These were also linked to oral dysbiosis, highlighting a bidirectional relation between host and microbiota.
ii)	The oral microbiota (bacteriome and mycobiome) of children was not associated with CRFs up to 6 months after delivery. Specific health, environmental, biological, and behavioral factors were associated with the oral microbiota of children up to 6 months after delivery. These may translate into protective and harmful effects on the microbiota of children, potentially having an impact beyond early life.
iii)	There was a concordance in potential opportunistic and pathogenic oral bacteria and oral fungi isolates between mother child-pairs, with a similarity in the genotypes of fungi found in mother and children. Furthermore, the oral bacteriome of mothers and children became increasingly more similar over time. In sum, the mother had a significant impact on the oral microbiota composition of the child in early life.

A espectroscopia vibracional é um registro da interação da radiação eletromagnética (infravermelho) com os movimentos de vibração dos núcleos que compõem uma molécula. Toda molécula, ou seja, todo sistema que contenha átomos ligados entre si, tem movimentos vibracionais, desde as moléculas mais simples (diatômicas), até as mais complexas (moléculas biológicas). Classicamente, a absorção/emissão de radiação por um sistema é devido à variação periódica de seu momento de dipolo elétrico, sendo a frequência absorvida (ou emitida) idêntica à frequência de oscilação do dipolo. Se o momento de dipolo, µ, ou uma das componentes (µx, µy, µz) oscila com a mesma frequência da radiação incidente, a molécula absorverá esta radiação. Cada absorção/ emissão é originária da transição entre dois níveis vibracionais, organizados na forma de bandas (%T: transmitância ou %A: absorbância) em função do número de onda, ῦ (cm-1). A transição entre níveis vibracionais em um espectro só ocorre para determinadas quantidades de energia, proporcionais ao número de onda da radiação. Neste trabalho foram analisadas duas amostras inicialmente desconhecidas pela técnica da Espectroscopia de Absorção no Infravermelho por Transformada de Fourier – FTIR. O objetivo deste trabalho consistiu em identificar a estrutura molecular completa das duas amostras. A análise foi realizada em um equipamento modelo Nicolet 6700 (ThermoElectronScientific), disponível no Laboratório de Análises Químicas do Centro de Desenvolvimento da Tecnologia Nuclear (CDTN). A partir do espectro vibracional obtido, foi possível correlacionar o número de onda correspondente aos picos de absorção no infravermelho com o número de onda associado aos movimentos vibracionais de alguns grupos funcionais. A partir desta correlação, foi possível a identificação da estrutura molecular completa das amostras. A amostra de no 19 foi identificada como um composto orgânico de fórmula mínima C19H18O7, enquanto a amostra de no 20 consiste em um composto orgânico de fórmula mínima C7H4Br2O2.

A espectroscopia de fotoelétrons excitados por raios X ou XPS (X-rayphotoelectronspectroscopy) é uma técnica experimental de análise que permite medir as energias de ligação entre elétrons e seus respectivos núcleos nos átomos.A técnica de XPS fundamenta-se no efeito fotoelétrico, fenômeno experimentalmente descoberto por Heinrich Hertz (1887) e teoricamente explicado por Albert Einstein (1905), sendo-lhe concedido o Prêmio Nobel de Física em 1921. Na técnica de XPS, uma amostra sólida em forma de pó é bombardeada com radiação de alta energia (raios X ou UV), o que faz com que os elétrons constituintes dessa amostra sejam excitados. Dos elétrons participantes do processo, uma parcela absorve energia suficiente e se move em direção à superfície da amostra, sendo, portanto, ejetandos para o meio externo (câmara de vácuo). Os elétrons ejetados (fotoelétrons) vão para um analisador de energia, onde suas energias cinéticas são registradas. Em seguida, vão para um detector, que conta o número de fotoelétrons em várias energias cinéticas. Sabendo a energia cinética dos fotoelétrons e a energia da radiação incidente, calcula-se a energia de ligação dos elétrons. Neste trabalho foi analisada uma amostra inicialmente desconhecida pela técnica de XPS por meio de um espectrômetro SPEC SENSE+UC. Objetivou-se a identificação da composição química da amostra pela correlação dos picos de energia obtidos com as energias de ligação de alguns elementos disponíveis na base de dados NIST (NationalInstituteof Standards and Technology). A amostra foi identificada como grafite, com teor de 99,86% de carbono e 0,14% de oxigênio.

Perubahan pola hidup yang terjadi dewasa ini mengakibatkan peningkatan angka kejadian penderita penyakit tidak menular (non communicable disease). Penyakit tidak menular menjadi salah satu masalah kesehatan masyarakat karena tingkat morbiditas dan mortalitas yang tinggi secara global, merupakan jenis penyakit yang tak bisa ditularkan oleh penderita ke orang lain, jenis penyakit ini berkembang secara perlahan dan terjadi dalam jangka waktu yang panjang. Penyakit tidak menular menimbulkan angka kematian yang tinggi tiap tahunnya dan dapat menjangkiti individu diberbagai usia maupun negara di seluruh dunia. Salah satu penyakit tidak manular yang banyak dialami oleh masyarakat di Indonesia adalah hipertensi. Hipertensi menjadi salah satu permasalahan kesehatan karena hipertensi merupakan salah satu pintu masuk atau faktor risiko penyakit seperti jantung, gagal ginjal, diabetes mellitus, dan stroke. Organisasi kesehatan dunia WHO memperkirakan sebanya 1,28 miliar orang dewasa berusia 30-79 tahun di seluruh dunia menderita hipertensi. Riset Kesehatan Dasar 2018 menyebutkan sebanyak 63 juta lebih penduduk Indonesia menyandang hipertensi. Seringkali penderita hipertensi tidak merasakan gejala atau tanda mengalami hipertensi sehingga tidak mendapatkan pengobatan dan penanganan secara cepat. Terdapat dua faktor risiko hipertensi yaitu, faktor risiko yang tidak dapat diubah (seperti usia, jenis kelamin, genetic) dan faktor risiko yang melekat pada penderita hipertensi dan tidak dapat diubah (merokok, diet rendah serat, konsumsi makanan tinggi lemak, konsumsi natrium, dyslipidemia, konsumsi garam berlebih, kurang aktivitas fisik, stress, berat badan berlebih / kegemukan, dan konsumsi alcohol). Tatalaksana hipertensi dilakukan melalui dua cara yaitu terapi medikamentosa dan terapi komplementer

Published: August 2024

The mass media play a pivotal role in portraying the images of various countries. Portrayal of Pak-US relations in the US media has always been a topic of interest for researchers. The proposed study focused on the portrayal of Pak-US relations in elite newspapers of U.S. and Pakistan i.e. The New York Times, The Washington Post, The News International and Dawn two years each before and after the 2018 General election in Pakistan. The objective of the study was to explore the nature of portrayal (favourable, neutral or unfavourable) given to the Pak-US relations by the mentioned print media with reference to Paulus foreign policies, importance and contribution of Pakistan in “war on terror”, Pak-US economic and strategic relations and domestic affairs of Pakistan. This study based on research questions “What was the extent of coverage given to Pak-US relations by elite press of Pakistan and America before and after 2018 general election in Pakistan?.” and Was there any difference in the amount of coverage given to the selected categories between selected press during selected time?" Out of 323 articles in context of Pak-US relations during selected time period, The New York Times published 49 (15.2 %), The News International published 114 (35.3), The Washington Post 55 (17.2%) and Dawn published 105 (32.5) articles. It is concluded that the 2018 General elections in Pakistan influenced the Pak-US relations. AFTER THIS EVENT, the US press changed its stance toward the portrayal of the Pak-US relations.
