In order to address many issues, such as the inconsistent and unreliable seeding process in traditional mechanical garlic seed metering systems (SMS), as well as the lack of ability to monitor the effectiveness of the seeding, a highly accurate electric-driven metering system (EDMS) was developed and created specifically for garlic seed planters. This study provided a description of the overall structure and functioning principle, as well as an analysis of the mechanism for smooth transit and delivery. A combination of an infrared (IR) sensor, Arduino Mega board, stepper motor, speed sensor, and a Wi-Fi module was employed to operate the EDMS, as well as monitor and count the quantity of garlic seeds during the planting process and determine the qualified rate (QR) and missing rate (MR).

In the past few decades, any type of organization, from factories to government organizations, the banking sector, or educational institutions concentrates on increasing profit margins. To achieve this, one of the key factors is to achieve maximum output with minimum resources (input). Therefore, having an optimal plan to apply the resources has become extremely important for organizations.

Protein supply to ruminants relies mainly on the flow of microbial crude protein (MCP) from the rumen, which is commonly assumed to primarily depend on energy supply. This study evaluated this assumption with recent data and tested if ruminally fermented organic matter (FOM) was a better predictor of MCP flow than total-tract digestible organic matter (DOM) and if more variables could improve the prediction of MCP flow. A previously published data set was extended by additional studies resulting in a data set of 139 studies including 407 treatment means, typical to Central European rations.

Mucin Colocalizes with Influenza Virus and Preserves Infectivity in Deposited Model Respiratory Droplets.

Environ Sci Technol

January 2025

Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, Virginia 24061, United States.

The stability of influenza virus in respiratory particles varies with relative humidity (RH) and protein content. This study investigated the decay, or loss of infectivity, of influenza A virus (IAV) in 1-μL respiratory droplets deposited on a surface with varying concentrations of mucin, one of the most abundant proteins in respiratory mucus, and examined the localization of virions within droplets. IAV remained stable at 0.

Objectives: Accurate preoperative staging of upper tract urothelial carcinoma is often difficult. Therefore, we aimed to investigate the preoperative factors associated with pathological upstaging in patients with upper tract urothelial carcinoma undergoing radical nephroureterectomy and to develop a risk-scoring system to assess pathological upstaging.

Methods: This retrospective study enrolled 386 patients with upper tract urothelial carcinoma who underwent radical nephroureterectomy at Tottori University Hospital and affiliated hospitals between January 2015 and December 2021.
