Outdoor systems performance and upgrade

Over the last two decades, the possibility of using RPCs in outdoors systems has increased considerably. Our group has participated in this effort by installing several systems and continues to work on their optimization, while simultaneously studying and developing new approaches that can use RPCs in outdoor applications. In particular, four detectors were deployed in the field at the Pierre Auger Observatory ...

Genetic evaluation for productive traits in endangered Portuguese Malhado de Al...

Malhado de Alcobaça (MA) is a swine breed from center west Portugal, recognized in 2003. Herdbook (LGMA) has information of >17,000 animals (1985-2022). It´s a very endangered breed with only 244 sows, 18 boars and 12 breeders. Within the scope of MA’s genetic conservation plan, for genetic evaluation, genetic parameters and fixed effects were estimated for birth weight (PN), for adjusted weight at 30 d (P30) a...

Avaliação morfo-funcional linear do cavalo Puro Sangue Lusitano com recurso à T...

O Regulamento do Livro Genealógico do cavalo Lusitano determina que qualquer candidato a reprodutor tem que ser avaliado por uma grelha de pontuação e por uma avaliação morfo-funcional linear (AML), através duma Tabela Padrão (TP). Esta TP inclui 63 características lineares, 45 morfológicas e 18 de andamentos e uma secção para assinalar imperfeições do animal, com 23 defeitos. A AML pressupõe uma linearidade en...

Equine embryo transfer: the effect of semen processing and donor mare managemen...

Embryo transfer (ET) is a biotechnology that allows to get more than one foal from a single mare during a breading season and also to prevent the removal of mares from their competition careers. Nevertheless, to achieve a successful outcome, the association of many factors must be considered, such as the management of donor and recipient mares, the stallions and the veterinarian´s experience. In this context, t...

Gastrointestinal parasites as a possible threat to an endangered autochthonous ...

Helminth and protozoan infections are responsible for important diseases in grazing sheep, which can be especially threatening in an autochthonous breed at risk of extinction like the Churra Galega Mirandesa Portuguese sheep breed. The aim of the present study was to determine the diversity, prevalence and burden of gastrointestinal parasites in these sheep and to assess the effects of deworming practices, coha...

Multi-purpose trigger system for medium particle detector devices

We report on an architecture of a multi-purpose trigger system based on inexpensive and off-the-shelf modules, with logic implemented in three levels, that can be used in a variety of small/medium systems just by writing a few registers using the accompanying software. The developed trigger algorithms are described in Very High Speed Integrated Circuits (VHSIC) Hardware Description Language (VHDL) and implement...

Use of topical local anesthetics to control pain during treatment of hoof lesio...

ABSTRACT - Hoof pathologies in dairy cows have a major effect on both production and animal welfare. Trimming of excess or diseased hoof tissue is essential for the treatment of many of these conditions. Trimming hoof lesions can cause severe pain, resulting in adverse behavioral responses with risk for animal and human safety. Interventions are usually carried out by nonveterinary technicians in the absence of...

MARTA: a high-energy cosmic-ray detector concept for high-accuracy muon measure...

A new concept for the direct measurement of muons in air showers is presented. The concept is based on resistive plate chambers (RPCs), which can directly measure muons with very good space and time resolution. The muon detector is shielded by placing it under another detector able to absorb and measure the electromagnetic component of the showers such as a water-Cherenkov detector, commonly used in air shower ...
