Study on the Strength of the Brake Pad of a Freight Wagon under Uneven Loading in Operation.

The paper highlights the results of determining the strength of the brake pad of a freight wagon under uneven loading in operation. The main reasons for the uneven loading on the pad have been found. A mathematical tool for determining the strength of the pad unevenly loaded has been proposed.

Sexual health challenges in migrant, immigrant, and displaced populations 2022-2023.

Purpose Of Review: This article reviews recently published research on sexual health challenges and HIV and sexually transmitted infections (STIs) among migrant, immigrant and displaced people (MIDP) worldwide. We aimed to identify current evidence gaps regarding HIV/STI epidemiology, sexual health needs and interventions.

Recent Findings: Incidence and prevalence of HIV, hepatitis B virus, hepatitis C virus and syphilis were higher among MIDP compared to host populations.

"": sexual and reproductive health needs and sexual behaviours among migrant people in transit through Panama.

Background: Unprecedented numbers of migrant people transiting through the Darién Gap at the Panama-Colombia border were recorded in 2021 and 2022. Data on sexual and reproductive health (SRH) needs and service provision among migrant people in transit is generally extremely sparse. This study aimed to collect personal accounts of sexual behaviours and SRH needs and access to services among migrant people in transit through Panama.

[Small salivary glands in the paratonsillar space in children].

Was to study the changes in the small salivary glands in chronic tonsillitis and paratonsillar abscess in children. A histological examination of the palatine tonsils of 22 children aged 5 to 14 years old who had a paratonsillar abscess and 18 children suffering from chronic tonsillitis was carried out. Fragments of small salivary glands, located both superficially, in the mucous membrane between the stratified squamous non-keratinizing epithelium and the lymphoid tissue of the palatine tonsils, and between the muscles of the amygdala were found in 42 of the 80 (52.

Effect of SiC Addition to AlO Ceramics Used in Cutting Tools.

In this study, the effect of the addition of silicon carbide to alumina ceramics commonly used in cutting tool applications is addressed. Performance of AlO-SiC composite cutting inserts during the machining of hardened steels and ductile iron was compared to the results obtained for a cutting tool made out of 99 wt.% AlO, AlO-TiC, AlO-TiC-ZrO, and AlO-TiN.
