Trends In Family Planning Uptake In Tanzania: An Analysis Of National Survey Data 2021-2022, Harun Yussuf Ayoub, Sabarinah Prasetyo

Jurnal Biostatistik, Kependudukan, dan Informatika Kesehatan

The purpose of this study is to uncover the socioeconomic and demographic factors that influence the usage of contraceptives by analysing trends and patterns in Tanzania's family planning uptake using data from national surveys. The results show that while Tanzania has made progress in increasing contraceptive prevalence from 27% in 2010 to 39% in 2021-22, disparities persist across socioeconomic and demographic lines. Women in urban areas, from higher wealth quintiles, and with higher educational attainment have significantly higher contraceptive prevalence rates compared to their counterparts. The study also reveals that the majority of women are aware of family planning methods, …

The increasing interest in coffee in all circles means that coffee production and quality must always increase due to consumer demands. One way to maintain the quality of coffee beans is by breaking them down using a huller machine. This research aims to improve the optimization of coffee machines by modifying the cylinder blades of huller machines with variations of 3, 4, 5, and 7 cylinder blades in terms of static loading design and quality and production capacity of coffee bean breaking. The experiment was carried out using 400 rpm and breaking 10kg of dry coffee cherries every time the …

Innovative Approaches For Improving Orc Performance: A Review Of Pure Fluids, Zeotropic Mixtures, And Nanoparticles, Ebenezer Kumi, Vasudevarao Veeredhi, Christopher Enweremad

Journal of Mechanical Engineering Science and Technology (JMEST)

Although the organic Rankine Cycle (ORC) is said to effectively capture low-grade heat, its commercialization has been limited because of working fluid constraints and inefficiencies resulting from operating at low temperatures. This study reviews the working fluids used in organic Rankine cycles and examines how nanoparticles could enhance the efficiency of the ORC, by enhancing the thermophysical properties of the working fluids. Results from this review showed that zeotropic mixtures of pure fluids, provide a viable approach to improving the thermophysical characteristics of organic working fluids and have the potential to achieve thermo-economic performance superior to that of individual pure …

Journal of Mechanical Engineering Science and Technology (JMEST)

Water quality is an important factor in aquaculture activities, including goldfish (Carassius auratus) farming. One approach to improving water quality is the use of nanofilters. This study aims to evaluate the performance of nanofilters made from Sargassum sp. with the addition of copper oxide nanoparticles. The method used involves the fermentation of bacterial cellulose from Acetobacter xylinum using Sargassum sp. extract as a medium, followed by homogenization and the addition of CuO-NPs at concentrations of 0.5%, 1%, and 1.5%, and subsequent oven drying. The nanofilter membrane will then be analyzed using SEM, XRD, and FTIR to characterize its properties. Performance …

Synthesis And In Vitro Testing Of Mg-6zn-Xhap Biocomposites From Beef Bone As Biodegradable Bone Implant Material, Jojor Lamsihar Manalu, Francisca Tjhay, Theodora Kristoforus, Sovian Aritonang

Journal of Mechanical Engineering Science and Technology (JMEST)

This study aimed to develop biodegradable Mg-6Zn hydroxyapatite (Mg-6Zn HAp) biocomposites for potential use in bone replacement applications. The hydroxyapatite (HAp) powders, sourced from cow bone, were synthesized through an eco-friendly and cost-effective process, leveraging bioresources for material sustainability. The Mg-6Zn and HAp powders were mechanically mixed through ball milling for six hours to ensure homogeneity. The resultant powder mixture was then subjected to isostatic pressing at a high pressure of 570 MPa, forming a dense coin-shaped composite with a 1.5 cm diameter. This coin was consolidated in a capsule furnace at elevated temperatures for one hour to enhance material …

Impact Of Natural Polymer Proportions On The Fire-Retardant Properties Of Bioplastics, I Gusti Ngurah Nitya Santhiarsa, Ni Made Dwidiani, I Gusti Ngurah Putu Tenaya, I Gede Artha Negara

Journal of Mechanical Engineering Science and Technology (JMEST)

This research investigates the influence of varying proportions of natural polymers on the fire-retardant properties of bioplastic. Tapioca starch (Manihot esculenta) and corn starch (Zea mays) were selected as the bioplastic materials, with different weight fractions employed in the analysis. These materials, as naturally occurring polymers, are biodegradable and serve as promising components in the development of bioplastics. Fire resistance testing was conducted in accordance with ASTM D635-03, utilizing weight ratios of tapioca to corn starch at 70:30, 60:40, and 50:50. The results included photographic documentation of each specimen alongside the corresponding outcomes from the fire resistance tests. These images …

The Impact Of Myosteatosis On Postoperative Outcomes And Survival Of Patients Undergoing Pancreatoduodenectomy For Suspected/Confirmed Malignancy, Paul Jenkins, Andrew Maccormick, Adam Streeter, Mark Puckett, Gemma Miles, Somaiah Aroori

Peninsula Medical School

BACKGROUNDS/AIMS: While the effects of myosteatosis are emerging, the evidence for its use as a predictor of outcomes in patients undergoing pancreatoduodenectomy (PD) still needs to be established. The study aims to evaluate the effect of myosteatosis on the shortand long-term outcomes of PD.

METHODS: We analyzed the effect of myosteatosis on the short- and long-term outcomes of patients who underwent PD between July 2006 and May 2013. Myosteatosis was measured retrospectively from preoperative computed tomography (CT) at the L3 vertebra level, and dichotomized as a binary exposure variable as < 38.5 Hounsfield unit (HU) for males, and < 36.1 HU for females.

RESULTS: A total of 214 patient (median age 62 years, …

TV viewing is associated with health risks, but existing measures of TV viewing are imprecise due to relying on self-report. We developed the Family Level Assessment of Screen use in the Home (FLASH)-TV, a machine learning pipeline with state-of-the-art computer vision methods to measure children's TV viewing. In three studies, lab pilot (n = 10), lab validation (n = 30), and home validation (n = 20), we tested the validity of FLASH-TV 3.0 in task-based protocols which included video observations of children for 60 min. To establish a gold-standard to compare FLASH-TV output, the videos were labeled by trained staff …

Unmasking The 'New Normal' And The 'Vernacular Of The Veracious' During A Pandemic, Aurelio S. Agcaoili

Budhi: A Journal of Ideas and Culture

This paper argues that the deployment of a figurative language like the phrase “new normal” and many other verbal formulations during a pandemic is a form of power and control by political leaders. This deployment is calculated and calculating as it is meant to condition the minds of the masses that depend on the ruling political class for clarity, guidance, and some form of redemption. These “weaponized” words are presented as expressions of the veracious—essentially a vernacular of power—by persons of authority for a semblance of credibility. There are at least two versions of the veracious that are at play …
