Authors: Adeleke Adelani Ismail , Waheed Mufutau Adekojo , Sobamowo Gbeminiyi Musibau , Siqueira Antonio Marcos de Oliveira 
Published: July 2024

In this present study, the flow behaviour of magnetorheological fluid in valve and shear modes for damping system is modelled and analysed. The fluid is modelled as viscoelastic fluid flowing between two parallel plates in pressure driven flow mode, and also as direct shear mode. In the work, the post-yield shear thinning or thickening behaviour of magnetorheological fluids are accounted for. The velocity and pressure distributions in the unsteady magnetorheological fluid flow between the electrodes of the damper are obtained by solving the momentum equation of the magnetorheological fluid flow using the Laplace transform method. There is an excellent agreement between the results of the present model and the results of the experimental studies. The adopted viscoelastic flow model describes that the rheological behaviour of the fluid is separated into distinct pre-yield and post-yield regimes. The fluid flow velocity, velocity gradient, and shear stresses have all been shown to be enhanced by an increase in the pressure drop. The viscosity of the fluid increases with an increase in the volume fraction of particles in the fluid, which causes the resistance of the fluid to flow to increase and thereby, reduces the fluid flow velocity. Fluid flow velocity is decreased as a result of increasing magnetic field strength. The design of clutches, rotary brakes, dampers, shock absorbers, prosthetic devices, polishing and grinding tools, etc. will all benefit greatly from the adoption of the current model.

The issue of abolition of wedding is one of issue in family. For islamic the cancellation of wedding mentioned as fasakh. Fasakh is the abolition of the agreement of marriage because of the abolition occurs when the terms and pillars of marriage uncomplete in a marriage. The effect of the abolition in a marrige made the bond between spouse is disengaged from the court of judgement.
The object study of this research is number of decision from: 0457/Pdt.G/2011/PA.Plg). This research desire to explain what about to be the primary consideration from judge in the court of religious in Palembang to decide and grant suit into number of decision from: 0457.Pdt.G/2011/PA.Plg and how perspective of islamic law towards primary decision of the judge into number of decision from: 0457/Pdt.G/2011/PA.Plg.
The research discover that the primary of judge’s decision to decide and grant suit of abolition of marriage from number of decision from: 0457.Pdt.G/2011/PA.Plg is due to the wedding between petitioner and defendant to be held by illegitimate guardian, which is in this issue that to be wedding guardian is the assistant of note-taker of marriage (P3N) who claim as guardian judge whereas P3N is not guardian judge. As for the perspective of islamic law towards primary of judge’s consideration to decide case of the abolition of wedding is based on Syafi’i sect, the guardian of wedding as the valid requirement, if wedding without the guardian, or wedding without the guardian’s permit or any guardian but have no right to be guardian wedding, therefore a wedding have to be abolished.

Published: July 2024

Fenomena permohonan isbat nikah di Pengadilan Agama Kuala Kurun dari tahun 2018 sampai 2022 terus mengalami peningkatan dibandingkan dengan perkara permohonan lainnya. Pada wilayah yuridiksi Pengadilan Agama Kuala Kurun pencatatan perkawinan masih minim terjadi dikarenakan banyaknya perkawinan yang masih dilakukan secara sirri atau pun secara adat sehingga perkawinan mereka belum terdaftar atau dicatat pada Kantor Urusan Agama, yang menyebabkan kesulitan saat mengajukan dokumen-dokumen resmi seperti Kartu Tanda Penduduk, Paspor dan sertifikat kelahiran anak dan administrasi negara lainnya dikarenakan tidak memiliki dokumen berupa akta nikah. Penelitian ini bertujuan untuk meneliti faktor-faktor apa saja yang mempengaruhi tingginya angka permohonan isbat nikah di Pengadilan Agama Kuala Kurun. Metode yang digunakan dalam penelitian ini adalah penelitian hukum empiris dengan menggunakan teknik random sampling dan pengumpulan data dengan observasi, wawancara, dan dokumentasi. Hasil temuan dari penelitian ini menunjukkan bahwa faktor penyebab tingginya permohonan isbat nikah di Pengadilan Agama Kuala Kurun adalah pertama, karena kurangnya pengetahuan pemohon tentang masalah hukum dan masih rendahnya kesadaran hukum masyarakat. Kedua, Pemohon sudah mendaftarkan pernikahan melalui Penghulu/Pembantu PPN tapi tidak diteruskan oleh Penghulu ke Kantor Urusan Agama sehingga mereka tidak mendapatkan buku nikah. Ketiga, faktor adat istiadat setempat yang masih diyakini oleh Pemohon. Keempat, faktor umur dikarenakan para Pemohon saat melakukan pernikahan belum cukup umur sehingga permohonan pernikahannya ditolak oleh Kantor Urusan Agama setempat. Kelima, faktor alam karena begitu luas wilayah Kabupaten Gunung Mas dan masih kurang memadainya akses jalan ke Kantor Urusan Agama yang masih jauh dan rusak sehingga menyebabkan Pemohon tidak mendaftarkan pernikahannya.

Published: July 2024

Penelitian ini bertujuan untuk menganalisis efektivitas program Lorong Wisata Kota Makassar sebagai wadah pemasaran makanan tradisional di Makassar. Penelitian dilakukan dengan metode kualitatif deskriptif melalui teknik pengumpulan data observasi, wawancara, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa program Lorong Wisata belum berjalan optimal dalam memasarkan makanan tradisional disebabkan rendahnya kunjungan wisatawan. Beberapa faktor penyebab rendahnya kunjungan wisatawan di Lorong Wisata antara lain daya tarik wisata yang masih kurang, minimnya motivasi kewirausahaan bagi masyarakat setempat, serta inkonsistensi pelaku UMKM dalam berjualan setiap hari. Rendahnya daya tarik wisata Lorong Wisata dipengaruhi oleh kurang menariknya desain dan tata letak lorong, minimnya promosi, serta kurang beragam dan menariknya produk makanan tradisional yang dijual. Minimnya motivasi kewirausahaan disebabkan kurangnya pelatihan dan pendampingan kepada masyarakat. Sementara inkonsistensi UMKM berjualan disebabkan keterbatasan modal dan sumber daya manusia. Maka dari itu, karena peningkatan daya tarik wisata, motivasi berwirausaha, dan konsistensi UMKM sangat diperlukan agar Lorong Wisata dapat berperan lebih optimal sebagai wadah pelestarian dan pemasaran makanan tradisional Makassar. Misalnya dengan meningkatkan desain lorong, promosi, diversifikasi produk, pelatihan kewirausahaan, pendampingan UMKM, dan bantuan permodalan. Penelitian ini penting sebagai evaluasi program dan rekomendasi kebijakan peningkatan peran Lorong Wisata dalam pelestarian dan pemasaran makanan tradisional Kota Makassar di masa mendatang secara berkelanjutan.

Published: July 2024

In the face of rising global demand and unsustainable production methods, cultivated crustacean meat (CCM) is proposed as an alternative means to produce delicious lobster, shrimp and crab products. Cultivated meat requires starting stem cells that may vary in terms of potency, and propensity to proliferate or differentiate into myogenic (muscle-related) tissues. We suggest that regenerating crustacean limbs harbor a range of stem cells suitable for cultivated meat production and present a humane tissue source because they can be accessed non-lethally. To investigate stem cell activity in this model, we have conducted RNA-Seq analysis across six stages of claw regeneration in the crayfish Cherax quadricarinatus (four pre-molt and two post-molt stages), along with histology and real time quantitative PCR (qPCR). Differential expression analysis revealed expression patterns of significantly up- or down-regulated genes in 14 functional categories. Relative expression of select stem cell target genes (including endocrine, myogenic, cell cycle and pluripotency factors) highlighted two growth peaks during pre-molt regeneration and limited stem cell activity after the molt. Histology and qPCR results support the overall finding that pre-molt limb regeneration stages harbor more stem cell activity, likely making them a more prolific cell source for CCM development.

This study presents, for the first time, the development of fibers with favorable properties for biodegradable wound dressings made from the Ecovio® (EC) polymer blend, composed of poly(lactic acid) (PLA) and poly(butylene adipate-co-terephthalate) (PBAT), incorporated with tea tree essential oil (TTE). TTE presented antimicrobial activity against Pseudomonas aeruginosa and Staphylococcus aureus, achieving minimal inhibitory concentrations of 15 and 7.5 mg/mL, respectively. The TTE was mixed with EC in a binary chloroform and formic acid (85/15 v/v) mixture, leading to homogeneous and wettable fibers by electrospinning. The EC/TTE fibers were characterized confirming the TTE in the fibers. The tests showed that TTE (0.5, 1.0 or 1.5 mL) improved the polymer blend electrospinnability. TTE (1.5 mL or 75 w% concerning the EC) lead to homogeneous fibers with an average diameter of 278 nm. TTE (75 w%) increased the wettability of the EC fibers from 120±2° to 69±1°. Preliminary bacterial adhesion and proliferation assays demonstrated that the EC/TTE fibers have anti-adhesive activity e seems to be more toxic against P. aeruginosa compared to S. aureus after 24 hours of incubation. Compatibility tests with human blood indicated that the EC/TTE fibers accelerate blood coagulation. The EC/TTE fibers exhibit promising chemical and biological properties (in vitro) for the development of wound dressings.
Numerical Modeling and Experimental Validation of Reverse Flow-Forming on 15CDV6 Seamless Tubes for Aerospace Application
Authors: Vikraman Gokul , Ramesh Ajith , Balasubramanian Venkataraman 
Published: July 2024

Abstract

Flow-forming is an unconventional incremental forming process that involves pressing and elongating a preform kept on a rotating mandrel with the aid of rollers. A 3D thermo-mechanical model is developed to simulate the reverse flow-forming of 15CDV6 Steel. This process can produce seamless cylindrical tubes in a single step with a high strength-to-weight ratio, reducing the need for additional manufacturing processes. Flow-forming also has an inherent advantage of producing tubes with almost uniform thickness distribution. The numerical model is validated by comparing the thickness distribution of the simulated formed tubes with those obtained from the experiments. This study also investigates the effect of input variables, like, axial stagger, percentage reduction, and feed ratio, on state variables like stresses, strains, equivalent plastic strains, and the measurable output parameters. The measurable output responses, like spring-back, diametral growth, ovality, and thickness, are predicted from the numerical results. Stress and strain distribution at relevant tube regions, such as the outer circumference, inner circumference, and roller contact zone, are also investigated. In addition, a significant contribution of this work is investigation of the strain-rate history of the process, which has direct implications towards the final tube geometry and structural integrity. The results have indicated that a higher percentage reduction leads to significant plastic deformation thereby increasing spring-back and ovality. Lower feed rates are found to result in a larger area of the tube material (locally) engaging in contact with the rollers, thereby leading to a higher ovality and diametral growth. In contrast, a higher axial stagger promotes larger spacing, greater support, and a controlled deformation, resulting in lower diametral growth and spring-back. Equivalent plastic strain is a crucial numerically-measurable output for material deformation, as it indicates structural integrity and also plays a significant role in crack formation. Notably, increasing the feed ratio was found to reduce the equivalent plastic strain since the amount of local contact with the rollers is reduced. However, increasing the percentage reduction was found to increase it globally. The Taguchi method is employed to develop the design of experiments and perform optimization of the process parameters.

Abstract

Background
Pulmonary function impairment has profound effects on patient quality of life, working ability, and healthcare utilization. Among individuals suffering from Coronavirus disease (COVID-19), a range of severity in respiratory symptoms is observed. We therefore investigated whether levels of biomarkers associated with respiratory function and inflammation in patients with COVID-19 upon admittance to the Emergency Department (ED) are predictive of long-term pulmonary function impairment among COVID-19 survivors.
Methods
In this prospective single-center study, patients were recruited upon attending their follow-up visits 4–5 months after experiencing severe COVID-19 infection. These patients underwent pulmonary function tests at the respiratory outpatient clinic as part of clinical standard procedure. Diffusing capacity of the lungs for carbon monoxide (DLCO) was chosen as the primary clinical measure and a diffusion deficit (DLCO <80% predicted) was the primary endpoint. DLCO and total lung capacity (TLC) were measured using the single-breath method. Forced Expired Volume in the first second (FEV1) and Forced Vital Capacity (FVC) were also measured. Baseline biomarkers, C-Reactive Protein (CRP), leukocyte cell counts, and soluble urokinase Plasminogen Activator Receptor (suPAR) were measured and the correlation with post discharge DLCO values were assessed.
Results:
A total of 110 patients with COVID-19 were enrolled in the study. Sixty-four (58.2%) were females, median age was 61.5 years and average BMI was 27.2. Of the participants, 53.7%, 43.5%, and 2.8% were never-smokers, former smokers, and current smokers, respectively; median tobacco exposure for current and former smokers was 18 pack-years.

Abstract

Background: Patients with oesogastric (OGC) and pancreatic ductal adenocarcinoma (PDAC) exhibit the highest rates of malnutrition in oncology. Current therapeutic strategies for localized PDAC and OGC (i.e., perioperative triplet chemotherapy and major abdominal surgery) curry a high risk of morbidity and mortality, particularly heightened in malnourished patients. Furthermore, surgery and chemotherapy may induce the nutritional deficiencies in these patients. Additionally, malnutrition impacts negatively all dimensions of patient’s life, including health-related quality of life (HRQoL) and survival. Scientific societies and national/international guidelines recommend nutritional support and adapted physical activity (APA) alongside oncological treatments as standard care but practices remain heterogeneous.
Methods: This is a single-arm, two-cohort (PDAC and OGC), multicenter, open-label study evaluating the feasibility of an 8-week trimodal prehabilitation program (supervised APA, nutrition, and psychological intervention) with nurse coordination for patients with PDAC (cohort #1) or OGC (cohort #2) scheduled for peri-operative triplet chemotherapy and surgery. The primary outcome will assess the feasibility of the intervention. Success will be defined by the completion of ≥75% of the planned APA sessions, 66% of the nutritional evaluations, and a psychological or psychiatric visit if needed by the Hospital Anxiety and Depression Scale. The main objective is to demonstrate, with a A’Hern design, that the rate of patients in each cohort successfully completing the prehabilitation program is clearly above a predetermined low rate (e.g. 50%). Secondary outcomes are: HRQoL, completion and complications of chemotherapy and surgery, and nurse coordination evaluation. Exploratory outcomes will include changes in body composition and muscle mass and function following the prehabilitation program.
Discussion: Prehabilitation, a multimodal emerging approach in oncology in France, faces several barriers to implementation including non-standardized modalities, limited territorial network of APA professionals, and lack of coordination. We hypothesize that remote supervision of the APA intervention with personalized sessions and nursing coordination of the program, could be an appropriate response to these current challenges.

Abstract

Bolivian Creole cattle populations evolved under low levels of breeding management and, during more than 500 years of natural selection, became adapted to various environments such as the contrasting highland and subtropical environments. Recently, highland Creole cattle were crossbred with Holstein to improve dairy production. The aim of this research was to evaluate the divergent adaptation through selection footprints of Bolivian Creole cattle from Andean highland and tropical lowlands, and to evaluate the effect of Holstein introgression in highland Creole. For this purpose, 130 Creole cattle (75 highland, 55 lowland) and 88 Holstein were genotyped using a microarray. The database was used to determine population structure and admixture and detect selection sweeps using FST, Rsb, XP-EHH and ROH. Ancestry inference suggested that selection peaks were not due to Holstein introgression. The NCBI database was used to retrieve genes from the common regions and then perform gene ontology analysis. The most prominent selection peaks were on BTA20 and BTA23 and included the PRLR (slick phenotype) and Class I and IIa BoLA genes. Other windows contained candidate genes for hypoxia (ANXA2, NDUFA4L2), angiogenesis, immune response (IL7R, IL6ST, IL31RA, C6, C7, STAT6, NKG2A, IRAK4, KLR, CLEC), oxidative stress (GSTA, HSD17B6) and morphological traits (PLAG1, CHCHD7, CAP2, ARL15). GO analysis revealed enrichment terms and pathways related to immune response, glutathione and retinol metabolism and reported QTLs for coat characteristics, immune response, and tick resistance. The results suggest the complex mechanism in the adaptation of Bolivian Creole cattle to the contrasting highland and subtropical environments.
