Authors: Mahmood Amal
Published: December 2024

The characteristics of heat transfer from an impinging jet emerging from an orifice are examined through experimental methods. The impact of the distance-to-diameter ratio (Z/D), jet velocity (UJ), and jet diameter (D) on heat transfer is examined. The values tested include 2, 4, 6, and 8 for (Z/D); jet velocities of 3 m/s, 5.1 m/s, and 7.2 m/s; and diameters of 10 mm and 20 mm. The findings indicate that, in all instances, the peak heat transfer coefficient is observed at the midpoint of the plate, directly beneath the centre of the air jet. It was also noted that elevating the air jet velocity from 3 m/s to 7.2 m/s resulted in an improved heat transfer ranging from 87% to 112% for the evaluated Z/D. Expanding the orifice diameter from 10 mm to 20 mm leads to a 42% improvement in the heat transfer rate.

Authors: Al-Dulaimi Mustafa J. , Hamad Faik
Published: December 2024

This work investigates the heat transfer inside a square duct experimentally in the presence of detached rectangular and triangular turbulence generators. The effect of the ratio of turbulence generators to the duct height (blocking ratio) is investigated for the values of 0.1, 0.15, and 0.2 for Reynolds number 15413. The results showed that turbulence generators have a positive effect on heat transfer. It was found that using rectangular and triangular turbulence generators augments the heat transfer by (3-9)% and (5-15)%, respectively. Also, it was revealed that increasing the blocking ratio of turbulence generators from 0.1 to 0.2 enhances the heat transfer by 6% and 10% for rectangular and triangular shapes, respectively.

In most applications, joining aluminum to copper using friction stir welding (FSW) is a primary manufacturing process followed by secondary forming processes. The aim of this study is to investigate the effect of FSW process parameters (speed and feed rate) on the formability of Al-Cu joints.  Aluminum and copper blanks were welded at three different rotational speeds, i.e., 910, 1280, and 1700 rpm, and three different feed rates, i.e., 16, 29, and 44 mm/min. The base metals used in this study were aluminum (Al-1050) and copper in two states, i.e., as received and annealed. The mechanical properties of the base metals and the produced compounds were evaluated by tensile and hardness tests. The aluminum-copper joints were drawn into flangeless U-shape and cup shape using FSW to examine the formability of the joints. The maximum tensile load, punch load, and forming index were obtained when Al was at 1700 rpm and 16 mm/min, i.e., h. The welding was performed with annealed copper at the highest rotational speed and lowest feed rate due to work hardening of the joint. However, the ductility was highest at 1280 rpm and 44 mm/min, i.e., at medium rotation and highest travel speed. It can be depicted that when the FSW Al-Cu joint is further used in the forming process, moderate rotation and high feed speed should be adopted for welding to avoid work hardening and improve the ductility of the joint.

Effect of Inlet Velocity on The Entrance Length of Laminar and Turbulent Flow in A Circular Pipe
Authors: Najim Farqad T.
Published: December 2024

This study uses numerical simulations performed with ANSYS-FLUENT to investigate the hydrodynamic entrance length for fluid flow in a circular pipe under both laminar and turbulent conditions. The effect of inlet velocity on entrance length and pressure drop was analysed. Two physical models with diameters of 15 cm and lengths of 10 m and 13 m were employed. The numerical results were validated against theoretical predictions, showing good agreement. The results indicate that entrance length increases with inlet velocity due to the extended development of the boundary layer. For laminar flow, entrance lengths of 1.46 m, 3.85 m, and 12.54 m were observed for velocities of 1, 3, and 10 m/s, respectively, while a turbulent flow velocity of 16.6 m/s yielded an entrance length of 5.8 m. Additionally, it was found that higher inlet velocities significantly amplify pressure drop due to increased friction and energy losses

Authors: Shakir Daniah Abdul Qahar , Mahdi Eman Turki
Published: December 2024

Skin diseases are the most common than other diseases. Skin diseases may be caused by fungal infection, allergy, bacteria, viruses, etc. Fungal disease affects more than billions people worldwide. The accurately of diagnosing skin fungal infections can be challenging in their early stages or present with symptoms, which mimic other dermatological disorders. The identification and categorization of skin fungal infections could be improved by recent developments in deep learning and artificial intelligence (AI). It offers a more effective and dependable substitute for conventional diagnostic techniques. Here we tried to focus on various methods for identifying fungal skin that rely on deep learning (such as transformers, convolutional neural networks, and hybrid models), the difficulties related to data diversity and availability, going over the shortcomings of current datasets, how data augmentation and synthetic data creation which might help close these gaps. We also investigate how improving interpretability and usability can help clinical uptake of AI-based diagnostic systems. Finally, the study concludes with suggestions for further research, highlighting the revolutionary potential of deep learning in dermatology and stressing the necessity of sophisticated model architectures, a wide range of high-quality datasets, and thorough clinical validation.

Authors: Udeaja Elias , Offum Peter , Ifejimalu Kera , Okafor Samson
Published: December 2024

The integration of countries into the global economy comes with exposure to risks that can be assessed through empirical investigation to uncover their impact on the domestic economy. Thus, this study attempts to answer the question of whether globalisation and geopolitical risk matter for stock market performance in Nigeria, given the growing interaction with the rest of the world. In doing so, the paper employs the dynamic ordinary least squares (DOLS) technique to analyse annual time series data on relevant variables from 1985 to 2021. The main finding indicates that globalisation and geopolitical risks significantly dampen the performance of the Nigerian stock market, whether it is measured by market capitalisation or by an all-share index. Accordingly, the study recommends the implementation of policies aimed at mitigating the risks associated with the globalisation and geopolitics to enhance the performance of the financial market.

Authors: Korkmaz Furkan , Kolip Ahmet
Published: December 2024

Cycloidal reducers have a unique and complex tooth profile design compared to conventional gear systems. Unlike standardized gear profiles, cycloidal reducers provide significant flexibility in design parameters such as module, profile modification coefficient, and eccentricity. However, these parameters interact in a complex manner, affecting both tooth profile formation and the overall performance of the reducer. Inaccuracies in selecting parameters may lead to problems such as excessive contact stress, gear deformation or reduced load transfer efficiency. This study aims to investigate the effects of design parameters on the formation of cycloidal tooth profiles and the operating performance of reducers. By analyzing the relationships and interactions between these parameters, the research provides a deeper understanding that will improve design processes, enhance performance, and contribute to future standardization efforts. As a result, this study aims to contribute to the development of cycloidal reducers that are structurally robust, efficient and suitable for high-performance operation.

Published: December 2024

Technical and Vocational Education and Training Institutions (TVETs) have been at the center of equipping students with prerequisite skills to fit into the job market by offering programmes aim to bridge the skills gap among students. However, in Kiambu County, rates of unemployment have continued to rise. Thus, the purpose of this study was to examine how TVETS act as catalysts for reduction of unemployment rates in Kiambu County. The study was anchored on the human capital theory. The study adopted mixed methodology and concurrent triangulation research design. Target population comprised 30 principals, 578 tutors and 4879 employed TVET graduates totaling 5487 respondents from which 372 respondents was sampled using Yamane’s Formula. Stratified sampling was adopted to create 12 strata based on the number of sub-counties in Kiambu County. From each sub-county, one TVET principal was selected using purposive sampling. However, from each of the sampled TVETs, 5 tutors and 25 employed TVET graduates were selected using simple random sampling. This enabled the researcher to sample 12 principals, 60 tutors and 300 employed TVET graduates. Questionnaires were used to collect data from employed TVET graduates whereas interview guides were used to collect data from principals and tutors. Qualitative data were analyzed thematically along the objectives and presented in narrative forms. Quantitative data were analyzed using descriptive statistics such as frequencies and percentages and inferentially using Pearson’s Product Moment Correlation Analysis with the help of Statistical Packages for Social Sciences and presented by using tables. The study found that there is an increasing rate of unemployment in Kiambu County for the last five years. To mitigate these challenges, TVETs have refocused the training to equip students with job-specific practical skills, entrepreneurship education, linkages and internship as well as integration of ICT and innovation. However, much is yet to be fully realized in improving status of unemployment rates. Thus, the study recommends that TVETs should collaborate closely with local and international industries to ensure that their training programmes align with current market demands. By continuously updating the curriculum to include emerging technologies, sector-specific skills, and soft skills like communication and problem-solving, TVET graduates will be better equipped to meet employers’ needs.

SONG FREQUENCY SHIFTS IN AN URBAN BIRD SPECIES OPTIMIZE ACOUSTIC TRANSMISSION INSIDE NOISY URBAN AREAS
Authors: Villarreal Mauricio , Barrantes Gilbert , Sandoval Luis
Published: December 2024

In animal acoustic communication is necessary that signals arrive to the receiver with reduced degradation and attenuation for a better transmission of the message. The noise pollution resulting from anthropogenic activities in cities reduces efficiency and efficacy of acoustic communication. Some species respond to high levels of noise increasing the minimum frequency of their vocalizations to avoid noise masking, but this may affect how sounds transmit in the environment because sounds with higher frequencies experience greater levels of attenuation and degradation. Using a transmission experiment, we analyzed how minimum frequency shifts, affect the sound transmission properties of the song of the House Wren (Troglodytes aedon) in urban areas that differ in the level of anthropogenic noise. We broadcasted songs with minimum frequencies between 1.2-1.8 kHz and the same songs with a minimum frequencies increment artificially of one semitone, increasing minimum frequencies to 2.1-2.6 kHz, in high and low noise level territories at four distances. We quantified signal-to-noise ratio, tail-to-signal ratio, blur ratio, and excess attenuation. Our results showed that songs with frequencies low minimum frequencies in low noise territories transmit with higher signal-to-noise ratio, and lower blur ratio and excess attenuation at longer distances.  Songs with increased minimum frequencies only showed higher signal-to-noise ratio in noisier territories at longer distances. These results support the hypothesis of producing frequency shift to increase the communication distance in noisier environments. This is the first experimental study that tests the effect of shifting frequency on acoustic communication transmission on bird territories with different noise levels.

Authors: Charles Charles , James James , Siregar Pablo Dwipa Ananta
Published: December 2024

Rencana pemindahan Ibu Kota Nusantara (IKN) ke Provinsi Kalimantan Timur sudah dimulai sejak tahun 2022. Dalam rangka memenuhi kebutuhan pendanaan, pemerintah kian gencar memasarkan IKN. Selain melalui promosi Marketing Investasi Indonesia (MII), pemerintah juga memberikan fasilitas perpajakan dan kepabeanan di IKN, dengan salah satunya adalah pengurangan tarif pajak PPh Badan sebesar 100% untuk penanaman modal di IKN. Namun, melalui analisis yang dilakukan, fasilitas insentif pajak di IKN dinilai kurang efektif, sebagaimana ditunjukkan oleh banyaknya anggaran IKN yang masih bersumber dari APBN. Untuk itu, pemerintah disarankan untuk menyesuaikan tarif pajak atas investasi menjadi 15% serta fokus pada peningkatan transaksi dan kemudahan administrasi.
Decisão 15/4 do Marco Global da Biodiversidade Kunming-Montreal: análise da repartição de benefícios no Brasil
Authors: Pereira Gomes Yuri
Published: December 2024

O presente artigo científico investiga as implicações e contradições do ordenamento jurídico ambiental em relação ao conhecimento e às populações tradicionais, bem como à biodiversidade. O objetivo é analisar os marcos legais nacionais e internacionais, destacando a Convenção sobre Diversidade Biológica, o Protocolo de Nagoya e a Decisão 15/4 do Marco Global de Biodiversidade Kunming-Montreal, e examinar a política de repartição de benefícios no Brasil. Utilizando um método dedutivo e qualitativo, a pesquisa se baseia em revisão bibliográfica e documental. Os resultados revelam que, embora existam avanços nas normas internacionais, a legislação brasileira, especialmente a Lei nº 13.123/2015 e o Decreto nº 8.772/16, apresenta limitações que dificultam a repartição justa e equitativa dos benefícios, priorizando interesses econômicos e desconsiderando os direitos das comunidades tradicionais. Conclui-se que é necessário reexaminar a legislação brasileira para alinhá-la com os princípios internacionais, promovendo a justiça e equidade na repartição de benefícios e protegendo os conhecimentos e patrimônios genéticos das comunidades. Este artigo contribui para o aprimoramento das políticas de proteção e repartição de benefícios de conhecimentos tradicionais associados e recursos genéticos no Brasil.

A metodologia utilizada foi a pesquisa de revisão bibliográfica, a partir de documentos como a Constituição Federal de 1988 e na Declaração Universal dos Direitos Humanos. Tratou-se do reconhecimento do trabalho como direito humano e da necessidade de inclusão social, por meio de políticas públicas, iniciativas privadas e conscientização individual para garantir o respeito e oportunidade para que não haja distinção e atitudes discriminatórias e preconceituosas, para as pessoas que não se encaixam no padrão heteronormativo. A criação de projetos para aperfeiçoamento escolar, profissional e inclusão na sociedade são necessários, pois foi evidenciada a dificuldade no decorrer da vida para a população de transgêneros e travestis.

Somali Navy from 1965 to the 1980s
Authors: Robinson Colin D.
Published: December 2024

Naval advising and assistance is an understudied field, in comparison to military advising and assistance on land. The author is only aware of three states whose navies have had to be rebuilt from nothing since 1999: East Timor, Iraq, and the varying efforts in Somalia. Advisory and assistance efforts of this type are helped by accurate data on the history that shapes and motivates new navies’ personnel. Yet, as regards Somalia, there is virtually no authoritative discussion of the history of the Navy. The Navy had its origins as a civilian port management body in the 1950s; grew under Soviet tutelage after its first vessels were transferred in February 1965; and received considerable Soviet advice and support. But it was severed from its Soviet training and support after the Soviets had to choose sides during the Ogaden War between Ethiopia and Somalia. That split appears to have led to a severe decline in operational readiness during the 1980s. In 1987 U.S. intelligence reporting, now declassified, shows only two operational fighting vessels, of a total of 18 ships, only making short patrols from one of the Navy’s three bases. After the collapse of the Somali state, some vessels fled to Aden, and possibly Mombasa. In the twenty-first century, international attention was roused by piracy off the Somali coast. Efforts to build new naval police forces, or a new Navy, in southern Somalia have faced constant challenges.
