Acne and hyperpigmentation are the most common problems in adolescents globally. Resveratrol and glabridin are proven to be effective against acne and hyperpigmentation. We developed a gel comprising these two actives for acne and hyperpigmentation treatment. The purpose was to establish a reliable UV method of analysis for quantification of resveratrol and glabridin, with high precision and accuracy. UV spectral analysis indicated 306nm and 281nm to be the λmax for resveratrol and glabridin, respectively, in methanol. The linearity studies conducted as per ICH guidelines Q2 R1 resulted in a correlation coefficient (r2 ) of 0.99. This method was used to assay the developed gel for resveratrol and glabridin content and demonstrated the suitability of this UV spectroscopic method for simultaneous quantification. It can be applied for other delivery systems with slight modification.

Published: September 2024

Inoculation is an essential metallurgical route for controlling solidification conditions of cast iron, consequently, in this study, the influence of varied percent ferrosilicon (FeSi) addition on microstructure and mechanical properties of grey cast iron (GCI) was investigated.  A 50Kg capacity rotary furnace was used to melt the charge (Auto engine block scrap, graphite, ferrosilicon (FeSi) and limestone). The casting was produced in a greensand mold with wooden rectangular pattern of length 50 mm and breadth 30 mm.  Chemical compositions and carbon equivalent values (CEVs) of the samples were determined, using Optical emission spectrometry (AR 4 metal analyzer) and the expression  respectively. Microstructures of the samples were obtained, using metallurgical microscope (model number NJF-120A). The tensile and hardness properties were measured, using Universal tensile tester and Rockwell hardness tester respectively.  From the results, C and Si were the major elements. Other trace elements were Mn, P, S and Al.  CEVs of both the control and inoculated samples were less than 4.3%. Microstructure of the control sample was comprised of primary dendrites and graphite flakes, while those of the inoculated samples were characterized by varied amount of more developed primary dendrites, longer graphite flakes and austenite dendrites. Also, a number of small MnS particles were observed in relative amount within the microstructures. Tensile and hardness properties of the FeSi inoculated samples were superior to the control sample. Highest tensile strength and hardness values of 76.62 MPa and 99.89 HRB respectively were obtained at the optimum inoculation of 1.5 wt. % FeSi.
Climate Change and Environmental Degradation: A Threat to Global Security
Authors: Osawe Anthony Ikhide
Published: September 2024

There is the global recognition that climate change and environmental degradation are caused by human activities which have considerably increased the atmospheric concentration of greenhouse gases. The consequences of climate change are: droughts which adversely affect the global poor who are engaged in agriculture; storm surges which destroy local infrastructures, housing and farm crops; and the rise of sea levels which adversely affect the inhabitants of small island states which could eventually be totally submerged. The implication is that an indefinite number of people are displaced. The serious repercussion for international security is that the world will very soon be flooded with climate refugees with no legal status under the Geneva Convention. Three urgent responses are required: (i) consideration of the right of future generations not to suffer from the adverse effects of climate change, (ii) assessing the relevant conceptions of global justice, and (iii) examination of existing protocols and international laws that provide effective defensive responses to climate change and attainment of sustainable environmental security and global peace.

Fibromyalgia is a widespread pain disorder characterized by chronic, diffuse pain, about 1 to 5% around world. While more prevalent in women and adults, it can also manifest in children and adolescents. The specific pathophysiology of fibromyalgia remains unclear, but it is associated with neuronal over sensitization, reduced conditioned pain modulation, cognitive dysfunction, memory loss, and impaired information processing. It has now been categorized as a somatic symptom disorder. This study aimed to investigate fibromyalgia, focusing on its potential hereditary connections and management practices. A key pathophysiological aspect of fibromyalgia is central sensitization, marked by increased functional connectivity with pre-receptive brain areas, decreased connectivity with antinociceptive areas, and alterations in central nervous system neurotransmitters, also in size and shape of specific brain areas. Fibromyalgia is not directly inherited from parents to offspring, it does exhibit a tendency to cluster within families. The serotonin transporter gene, characterized by single nucleotide polymorphism with "S" (short) allele, is more prevalent in individuals with fibromyalgia and psychological distress. In conclusion, fibromyalgia is a widespread pain disorder with a substantial impact on the central nervous system, resulting in significant disability and an elevated risk of chronic diseases. Early diagnosis and intervention can minimize the impact of fibromyalgia. Physical therapy and non-drug therapies should be customized for each patient. The FDA has approved three drugs including pregabalin, duloxetine, and milnacipran for fibromyalgia treatment.

Published: September 2024

Amid the global COVID-19 crisis with over 762 million cases by 2023, reaching 775 million by 2024, this study examines the critical role of ferritin in diagnosing and managing COVID-19, emphasizing its correlation with disease severity and patient outcomes, especially in Pakistan, where data is scarce. At Benazir Bhutto Hospital in Rawalpindi, this study analyzed medical records of 376 COVID-19 patients aged 25-87 between April 2020 to August 2021, categorizing them by severity. Biochemical parameters, as well as ferritin, AST, ALT, urea, creatinine, and LDH, be assessed using Beckman Coulter AU480, with group differences analyzed via nonparametric tests and SPSS 25. Among 376 patients, predominantly aged 45-65 with a male majority (56.6%), 88.2% had comorbidities and 34.8% deceased during hospitalization. Elevated levels of ferritin, AST, urea, creatinine, and LDH were strongly linked to mortality (p < 0.001). The patients in the 66-90 age group had significantly increased risk of death from COVID-19 than those aged 45-65, by an adjusted odds ratio (AOR = 4.973; 95% CI: 2.517, 9.826; p = 0.0001). Additionally, individuals in the upper ferritin tertile were more susceptible to death, with an AOR of 3.443(95% CI: 2.012, 5.892; p = 0.0001) in contrast to those in middle and lower ferritin tertiles. These findings underscore the predictive value of age and ferritin levels in COVID-19 mortality. Increased ferritin levels stand out as a vital indicator, along with age, for forecasting mortality in COVID-19 patients, highlighting the pressing need for prompt intervention and customized treatment approaches.

Published: September 2024

One of the most common causes of maternity and neonatal fatalities and mortality is Pre-eclampsia (PE) which is responsible for 14% of global maternal deaths. The condition is primarily attributed to impaired trophoblastic invasion, which increases uterine artery pulsatility index (PI). A predictive analysis was done at Swat Medical College and Women's Hospital in Mardan, Pakistan from June 2022 to June 2023, including 218 pregnant women aged 11-13+6 weeks. Females with multifetal pregnancies, congenital fetal anomalies, and pre-existing medical conditions were excluded from this research. Uterine artery the Doppler and the PAPP-A testing were done to screen the conditions. Of 624 screened women, 218 were included in the final analysis using SPSS. The study population's mean age was 28 years, with 59% primiparous and 41% multiparous women. The incidence of PE was 35.5%, and gestational hypertension was 22.5%. Women developing hypertensive disorders had significantly higher mean uterine artery PI (2.11) compared to normotensive women (1.21, p=0.01), and significantly lower mean PAPP-A MoM levels (0.78 vs. 1.42, p<0.001). Coupled aberrant uterine blood vessels PI and PAPP-A predicted PE with high significance (p<0.001). Uterine artery in the first trimester Doppler and PAPP-A levels are effective in predicting pre-eclampsia in a South Asian population. Implementing these screenings could enhance early detection and management of PE, potentially reducing associated morbidity and mortality.

Published: September 2024

O suporte social é um importante fator para o funcionamento e o bem-estar psicológico ao longo da vida das pessoas, principalmente para aquelas em sofrimento mental. O presente trabalho tem objetivo de compreender como um grupo de suporte de pares identifica e articula redes de suporte social entre pessoas com a experiência de audição de vozes. Trata-se de um estudo qualitativo onde foram gravados e transcritos 10 encontros de um grupo de ouvidores de vozes. A partir da análise temática dos dados percebeu-se que os participantes reconheciam a família e o grupo como redes de suporte social importantes em momentos desafiadores no manejo das experiências. Ainda, há um reconhecimento de que é necessário ampliar redes e contar com um número maior de pessoas em situações difíceis. Para isso, o grupo se organiza para articular outras redes de suporte identificando pessoas que estariam mais disponíveis para oferecer apoio e realizando convites para as pessoas participarem do grupo, pois acreditam que a presença dessas pessoas no grupo ajudaria na compreensão da experiência de audição de vozes. Grupos de suporte de pares se estruturam enquanto uma estratégia interessante para o estabelecimento de redes de suporte mais robustas e para ampliação de outras redes.

Published: September 2024

As discussões acerca do crescimento econômico e desenvolvimento humano têm sido amplamente debatidos na literatura. Enquanto que o crescimento econômico é comumente associado à expansão da economia em um determinado período de tempo, o desenvolvimento humano inclui as questões de bem-estar social. O crescimento econômico é um dos principais instrumentos para a concretização do desenvolvimento humano, contudo, não necessariamente reflete condições melhores de vida para a sociedade. O desempenho eficiente está associado à capacidade de utilizar, da melhor maneira possível, os recursos disponíveis e de aproveitar, ao máximo, as condições para obter um desempenho ótimo. Neste contexto, o objetivo deste estudo é duplo, o primeiro é o de analisar a eficiência social dos países pertencentes aos grupos econômicos BRICS e G7. E para isso, aplicou-se a Análise Envoltória de Dados (DEA) no modelo BCC com orientação ao output. Num segundo momento, e considerando ainda a importância da Alfabetização Financeira nas questões relacionadas ao desenvolvimento de um país, também realizou uma análise comparativa dos resultados de eficiência social com as taxas de Alfabetização Financeiras publicadas pela Pesquisa Global FinLit, a fim de avaliar se os países mais eficientes possuem melhores taxas de Alfabetização Financeira. Os resultados encontrados através da avaliação da eficiência composta normalizada, demonstraram que com exceção da Itália, Japão e EUA, para os demais países analisados existe uma relação mesmo que mínima destes dois aspectos: Eficiência Social e Alfabetização Financeira. O estudo também ofereceu recomendações práticas para abordar as limitações identificadas e melhorar futuras análises utilizando a DEA.

Cultivation of Youth Patriotism in the New Era: Current Situation, Objectives and Practical Approaches
Authors: Fang Shuhui
Published: September 2024

Youth patriotism education is an important part of maintaining national unity and promoting the growth and success of young people to realize the great rejuvenation of the Chinese nation in the new era. However, youth patriotism education in the new era presents the following status quo: firstly, the education method and content are single and boring; secondly, it is deeply impacted by the negative information on the Internet and the invasion of diversified ideologies and cultures; and thirdly, the cultural self-confidence is weakened, and the influence of traditional culture is declining. Patriotic education for young people in the new era should aim at realizing young people's emotional identity, ideological identity and behavioral identity of knowledge and action. To this end, patriotic education in the new era can be adjusted from the adjustment of the form and content of patriotic education, strengthening the governance of multiple subjects in cyberspace, as well as basing on traditional culture and firming up cultural self-confidence, with a view to enhancing the effectiveness of patriotic education for young people in the new era.

A Systematic Review of Speech Fluency Measurement in L2 Monologues and Dialogues
Authors: Huang Wen
Published: September 2024

This study synthesises measures of L2 speech fluency in both monologues and dialogues. About monologue fluency measurement, we provide a synthesis of measurement based on Skehan's (2003) three dimensions (speed, breakdown, and repair) and discrepancies among scholars. As for dialogue fluency, the limited number of studies precludes a conclusion of well-established measurement. Furthermore, the reasons for the paucity of studies in this area are elucidated. The study revealed inconsistencies in the standardisation and methodological definitions employed by scholars in monologue fluency research, resulting in a lack of uniformity in the data collected. Concerning dialogues, there is a notable absence of theoretical and operational frameworks.

Penelitian ini bertujuan untuk mengevaluasi pelaksanaan Training Instructor Course (TIC) di Pusat Pengembangan Sumber Daya Manusia Perhubungan Udara (PPSDMPU) dengan menggunakan model Kirkpatrick. Pelatihan TIC dikembangkan dan distandarisasi oleh International Civil Aviation Organization (ICAO). ICAO telah mengembangkan evaluasi level 1, 2 dan 3 untuk pelatihan TIC, namun belum mengembangkan evaluasi level 4. Evaluasi level 1 dan 2 dapat diakses oleh PPSDMPU dari Trainair Plus Electronic Management System (TPEMS). Hasil evaluasi level 1 sangat baik dengan nilai rata-rata 4,73. Hasil evaluasi level 2 menunjukkan bahwa seluruh peserta dinyatakan lulus dengan nilai rata-rata 87,1. Hasil evaluasi level 3 dikelola langsung oleh ICAO sehingga tidak bisa diakses oleh PPSDMPU. Namun peneliti melakukan survei dengan hasil menunjukkan bahwa adanya peningkatan kualitas perilaku dalam mengelola pembelajaran. Berdasarkan hasil evaluasi level 3, dapat disimpulkan pada evaluasi level 4 akan terjadi peningkatan hasil belajar murid sebagai akibat peningkatan kompetensi pedagogi instruktur.

Layanan radio komunikasi penerbangan antara pemandu lalu lintas (Air Traffic Control) dan penerbang (pilot) harus dijaga dalam kondisi baik tanpa gangguan dan tidak terputus, karena keselamatan penerbangan menjadi prioritas utama. Tujuan pada penelitian ini untuk mengurangi frekuensi harmonik yang tidak diinginkan yang ditimbulkan dari pemancar sehingga efek interferensi frekuensi pada adjacent channel dapat dikurangi. Alat ini hanya akan melewatkan frekuensi yang diharapkan. Bandpass filter ini diatur sedemikian rupa sehingga dapat digunakan pada range frekuensi VHF Air Ground Communication yaitu 118 – 137 MHz dengan model tunable combline yang memiliki selektifitas tinggi pada channel frekuensi yang digunakan. Metode penelitian ini adalah perancangan dan analisis alat yang terdiri dari beberapa saluran transmisi batang silinder  (slabline) yang terhubung ke ground pada salah satu ujungnya dan terpasang variable capacitor bersama dengan ground di bagian ujung yang lainnya. Hasil simulasi dan pengukuran parameter insertion loss (S21) dan return loss (S11) masih memenuhi standar perancangan pada semua range frekuensi VHF A/G. Kinerja peralatan diujicoba dengan frekuensi kerja 120,0 MHz pada peralatan pemancar radio VHF AG Merk Icom A-120 dengan daya 9 Watt, Merk Rohde & Swarch SU4200 dengan daya 5 Watt, serta Dittel FSG-2T dengan power output 3 Watt. Hasil ujiocba pemakaian pada peralatan masih dapat digunakan dengan hasil VSWR masih kurang dari 2 dan penurunan power output kurang dari 20% dari power nominal.

Pesawat Boeing 737-200 di produksi dari tahun 1967-1988, sehingga peralatan navigasi pada era tersebut belum banyak kemanjuan di banding saat ini, sehingga perlu dimodifikasi dengan melakukan penambahan peralatan navigasi yang salah satunya adalah ATC Transponder. Peralatan ATC Transponder terdiri dari 2 komponen utama, yaitu Transceiver (alat pemancar dan penerima sinyal gelombang radio) dan antena. Peralatan transceiver dipasang pada cockpit, sedangkan antena dipasang pada fuselage skin yang berlokasi di body station 427 bagian atas. Untuk menguatkan pemasangan antena, maka diperlukan penambal (doubler). Berdasarkan data SRM Boeing 737-200, geometrinya berukuran panjang 165,1 mm, lebar 266,7 mm dan tebalnya 2 mm. Penambal direkatkan dengan menggunakan paku keling sebanyak 74 dengan diameter 4,76 mm pada fuselage skin. Fuselage skin dimodelkan berupa pelat utama (exixsting skin) dengan ukuran panjang 354,33 mm, lebar 401,4 mm dan tebal 1,8 mm. Material pelat utama dan penambal adalah aluminium T2024-T3, modulus elastisitasnya 72 GPa. Data-data dari material dan  SRM Boeing 737-200 dianalisis menggunakan metode elemen hingga dengan software PATRAN NASTRAN. Hasil analisis menunjukan bahwa resultan beban geser maksimum yang terjadi pada paku keling adalah sebesar 675,76 N dan paku keling yang mendapat beban maksimum tersebut posisinya paling jauh dari lubang. Berdasarkan batas nilai kekuatan geser maksimum paku keling dengan diameter 4,76 mm sebesar 4498 N, maka paku keling masih aman digunakan
