prices of meat in the international and a nation's internal markets tend to be closely related to each other. this relation could be sometimes harmful and due to lagged responses, meat prices at the internal market would subsequently increase as input prices increase at either the internal or international market. price uncertainty and transmition are two important problems facing a nation...

The etiology of atopy is unknown. Its family distribution suggests transmissibility. Populations moving from countries with a low incidence to those with a high incidence increase to the higher rate. African and New Guinea village groups developed asthma with return of individuals who have acquired atopy in the city. Protection (and possibly immunity) develops with early exposure to child care ...

Morbidity surveys in certain regions during the COVID-19 pandemic have established that infection spreads a wave-like manner characterised with peaks and troughs incidence. According to analysis of epidemic development Russia, surges infections are mainly driven by seasonal factors, insufficient herd immunity, emerging SARS-CoV-2 variants increased transmissibility. The aim study was analyse en...

Mountain bikers often report impaired finger sensitivity caused by mechanical vibrations and misalignment between the wrist forearm when using traditional (cylindrical) handles. The aim of this study was to evaluate acute effects ergonomic clip-on handles that allowed hand rest on medial carpal bone, muscular activity, vibration transmissibility cycle ergometer body segments, handgrip strength....

Abstract Existing quasi-zero stiffness (QZS) isolators are reviewed. In terms of their advantages, a novel X-shape QZS isolator combined with the cam-roller-spring mechanism (CRSM) is proposed. Different from existing isolators, oblique springs used to enhance negative system. Meanwhile, CRSM eliminate gravity loading mass, while structure leaves its static position. The demonstrated and classi...

It is now well appreciated that population structure can have a major impact on disease dynamics, outbreak sizes and epidemic thresholds. Indeed, on some networks, epidemics occur only for sufficiently high transmissibility, whereas in others (e.g. scale-free networks), no such threshold effect exists. While the effects of variability in connectivity are relatively well known, the effects of cl...

In this work, by replacing the traditional solid spokes with colloidal spokes, a vehicle wheel with a built-in suspension structure is proposed. Following the background and description of the wheel system, firstly, a vibration model of the wheel equipped with colloidal spokes is proposed, and based on such model the equivalent damping coefficients and spring constants are identified. Then, a m...

The size of infectious disease outbreaks frequently depends on climate influences as well as on the level of immunity in the host population. This is particularly the case with vectorborne and waterborne diseases, for which pathogen transmissibility critically depends on ecological conditions. Here, a mathematical model that was applied to the bacterium Vibrio cholerae to understand its disease...

The Ebola virus in West Africa has infected almost 30,000 and killed over 11,000 people. Recent models of Ebola Virus Disease (EVD) have often made assumptions about how the disease spreads, such as uniform transmissibility and homogeneous mixing within a population. In this paper, we test whether these assumptions are necessarily correct, and offer simple solutions that may improve disease mod...

The Burkholderia cepacia complex is an important group of pathogens in patients with cystic fibrosis (CF). Although evidence for patient-to-patient spread is clear, microbial factors facilitating transmission are poorly understood. To identify microbial clones with enhanced transmissibility, we evaluated B. cepacia complex isolates from patients with CF from throughout Canada. A total of 905 is...
