Published: January 2025

Sifat mekanik komposit termoplastik berpenguat serat karbon dipengaruhi kinerja ikatan antarmuka antara serat dengan matrik. Dalam penelitian ini parameter proses berupa suhu pencairan matrik dan perlakuan kriogenik serat karbon telah dioptimasikan dalam pembuatan filamen komposit untuk meningkatkan interfacial shear strength (IFSS). Filamen komposit polipropilena yang diperkuat serat karbon dibuat dengan menggunakan mesin ekstrusi-pultrusion. Temperatur peleburan divariasikan pada 180 oC, 190 oC, dan 200 oC. Serat karbon terlebih dahulu direndam dalam nitrogen cair dengan variasi waktu 10, 15, dan 20 menit untuk meningkatkan kekasaran permukaan serat. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh temperatur leleh dan perlakuan kriogenik serat karbon terhadap IFSS filamen komposit. Nilai IFSS diukur menggunakan uji pull-out, sedangkan morfologi permukaannya diamati menggunakan Scanning Electron Microscope. Hasil penelitian menunjukkan bahwa perlakuan serat dengan nitrogen cair memberikan pengaruh lebih dominan dalam peningkatan IFSS. Perlakuan serat secara kriogenik selama 20 menit direkomendasikan karena memberikan kekasaran permukaan tertinggi. Kombinasi parameter proses yang memberikan IFSS tertinggi adalah dengan perendaman serat karbon selama 20 menit dan aplikasi suhu pencairan matrik sebesar 190 oC.

The role of automatic machining with the help of computer programming such as Computer Numerically Controlled (CNC) has become commonplace today in both large and small industrial sectors or micro industry. CNC is a manufacturing process where previously programmed computer software is converted into code that can automate machining movements, one of which is the milling or lathe process. CNC performance is determined by machining output power. For micro industrial or laboratory scale, CNC with low power is usually used to cut soft materials such as wood, acrylic, aluminum and others. This is the basis for this research to look at the influence of machining parameters such as speed, depth of cut and feed rate on the surface roughness (Ra) of AI6061BE aluminum workpieces in the dry machining process on a mini CNC unit with a maximum spindle power of 500 watts. This research uses an experimental design based on the Taguchi method and takes the form of an L16 (43) orthogonal matrix. The chisel used is a Straight End Mill 2 fluke carbide chisel. The experiment was carried out 4 times cutting in the positive x-axis direction and 4 times in the negative x-axis direction for each variation of machining parameters. From the test results, surface roughness, feed rate is a parameter that is more influential than speed and depth of cut.

Published: January 2025

Background
The incidence of many common chronic childhood conditions has increased globally in the past few decades, which has been suggested to be potentially attributed to antibiotic overuse leading to dysbiosis in the gut microbiome.

Objective
This linkage study will assess the role of antibiotic use in utero and in early life in the development of type 1 diabetes (T1D), attention-deficit/hyperactive disorder (ADHD), and inflammatory bowel disease.

Methods
The study design involves several retrospective cohort studies using linked administrative health and social data from Statistics New Zealand’s Integrated Data Infrastructure. It uses data from all children who were born in New Zealand between October 2005 and December 2010 (N=334,204) and their mothers. Children’s antibiotic use is identified for 4 time periods (at pregnancy, at ≤1 year, at ≤2 years, and at ≤5 years), and the development of T1D, ADHD, and inflammatory bowel disease is measured from the end of the antibiotic use periods until death, emigration, or the end of the follow-up period (2021), whichever came first. Children who emigrated or died before the end of the antibiotic use period are excluded. Cox proportional hazards regression models are used while adjusting for a range of potential confounders.

Results
As of September 2024, data linkage has been completed, involving the integration of antibiotic exposure and outcome variables for 315,789 children. Preliminary analyses show that both prenatal and early life antibiotic consumption is associated with T1D. Full analyses for all 3 outcomes will be completed by the end of 2025.

Conclusions
This series of linked cohort studies using detailed, complete, and systematically collected antibiotic prescription data will provide critical new knowledge regarding the role of antibiotics in the development of common chronic childhood conditions. Thus, this study has the potential to contribute to the development of primary prevention strategies through, for example, targeted changes in antibiotic use.

Published: January 2025

The heat exchanger is an intermediary for two or more fluids that flow both inside and outside of the heat exchanger to distribute heat. This process was aimed to increase efficiency levels in the process industry. One of the suitable materials for the tube is UNS C44500, also known as admiralty brass consists of 70Cu-30Zn, which has high thermal conductivity and good corrosion resistance. However, admiralty brass was susceptible to stress corrosion cracking (SCC) when faced with nitrate since the tube was also loaded by internal stress. Moreover, SCC was also exacerbated by dezincification. The C-ring test method examined the effect of nitrate compounds and dezincification on SCC in C44500 Tube components. Tensile stresses varied between 15, 45, and 85% of yield strength, which were immersed into nitrate solutions consisting of NaNO3 and Cu(NO3)2. Some specimens were washed using 20% ​​HCl to bring up dezincification. The results obtained that SCC occurred at the highest Cu(NO3)2 concentration, identified by longitudinal crack and passivity breakdown. All of the dezincified specimens were found cracked due to SCC after immersion into 1 M Cu (NO3)2, while un-dezincified were failed when given tensile stress between 45% to 85% of maximum yield strength.

Published: January 2025

Resumo:
Os fluxos e usos que imprimimos na cidade transformam, ressignificam e possibilitam um novo olhar, ao longo do tempo, das rupturas e descontinuidades socioespaciais. Esta pesquisa volta-se para a perspectiva da sustentabilidade socioambiental, selecionando como elemento de análise a economia municipal. Analisamos as marcas impressas pelos processos socioespaciais no sentimento de pertencimento dos cidadãos, na perspectiva do trabalho, consumo e permanência do capital no território, pensando que a população possa voltar-se para a cidade, como espaço de vivência, convivência e afetividade em razão dos efetivos e constantes usos e apropriações espaciais. Alvorada foi escolhida para este estudo por compor uma nova centralidade a partir de sua emancipação do município de Viamão, o maior da região metropolitana leste de Porto Alegre/RS. Na leitura desses processos socioespaciais que proporcionam ou não a sustentabilidade socioambiental e o sentimento de pertencimento, tecemos recortes espaciais, a partir de um estudo com base no desenvolvimento dos setores da economia municipal, para compreender suas contribuições para que o capital permaneça no município, em termos de consumo, empregabilidade e consequente ou não pertencimento pela permanência dos cidadãos em Alvorada, o que consideramos como processos lugarizantes. Para isso, analisamos índices relacionados ao desenvolvimento humano e econômico do município, entrevistamos empreendedores locais e propusemos questionário, respondido por cidadãos alvoradenses. Os dados obtidos possibilitam algumas considerações que não se esgotam neste trabalho, mas que reforçam a necessidade premente da gestão pública municipal de Alvorada investir em políticas, planos, programas e ações que promovam uma relação de pertencimento da população ao território municipal e de sustentabilidade socioambiental local.

Abstract

OBJECTIVE
To determine the relationship between hoof surface (HS), hoof wall (HW), and lamellar tissue (LAM) temperature during distal limb cooling and evaluate 4 cooling methods in ambulatory horses over extended periods using HW to estimate LAM temperature.

METHODS
8 healthy, university-owned horses were enrolled. Temperature was measured over 4 hours at LAM, HS, and HW for 4 cooling methods: ice sleeve (SLEEVE), ice pack system (ICEPACK), low-volume ice water immersion (LV-IMMERSION), and high-volume ice water immersion (HV-IMMERSION). The relationship between HW, HS, and LAM was mathematically modeled, generating a method-specific correction factor to predict LAM based on HW. Hoof wall temperature was then measured over 8 hours with horses free in a stall (LAM was estimated using HW). Mixed-effects linear regression was used to compare cooling methods.

RESULTS
HV-IMMERSION and LV-IMMERSION significantly decreased LAM temperature over 4 hours (P < .001), whereas ICEPACK and SLEEVE did not. Lamellar tissue temperature estimated using HW showed good concordance (ρc = 0.93 [0.93 to 0.94]; P < .001) and correlation (r = 0.93; P < .001) with measured LAM temperature. In horses free in the stall for 8 hours, the estimated LAM temperature decreased significantly with HV-IMMERSION (−20.4 °C [−22.9 to −17.8]) and LV-IMMERSION (−14.9 °C [−17.7 to −12.1]) compared to control (32.7 °C [32.2 to 33.2]; P < .001) but did not decrease with ICEPACK (−2.7 °C [−5.6 to −0.3]; P < .08) or SLEEVE (−1.8 °C [−5.6 to −2.0]; P < .4).

CONCLUSIONS
HV-IMMERSION and LV-IMMERSION were superior to ICEPACK and SLEEVE for lamellar cooling.

CLINICAL RELEVANCE
Immersion of the distal limb in ice and water is most effective for cooling the digital lamellae under clinically relevant conditions.
