Modelo térmico para estimar la potencia de cocción estándar de cocinas solares

Paper presents of some aspects of thermal physics necessary for the development of small-scale solar cookers by developing a computational semi-empirical thermal model. The free parameters of the models are adjusted with data obtained from an experimental design, which consists of heating a fluid, exposing the cooker to radiation that produces an array of incandescent lamps to...

Evolution of Young Sex Chromosomes in Two Dioecious Sister Plant Species with Distinct Sex Determination Systems

In the last decade, progress has been made in methods to identify the sex determination system in plants. This gives the opportunity to study sex chromosomes that arose independently at different phylogenetic scales, and thus allows the discovery and the understanding of early stages of sex chromosome evolution. In the genus Silene, sex chromosomes have evolved independently in...

Evaluating the effectiveness of infliximab on perianal fistulizing Crohn’s disease by magnetic resonance imaging

Data on the radiologic evaluation of perianal fistulizing Crohn’s disease (PFCD) naïve to anti-tumor necrosis factor therapy are scarce, especially in Asian populations. We assessed the effectiveness of infliximab (IFX) on PFCD and explored predictors of ‘deep remission’ based on clinical and radiologic assessments.

Homo sapiens, Homo neanderthalensis and the Denisova specimen: new insights on their evolutionary histories using whole-genome comparisons

After a brief review of the most recent findings in the study of human evolution, an extensive comparison of the complete genomes of our nearest relative, the chimpanzee (Pan troglodytes), of extant Homo sapiens, archaic Homo neanderthalensis and the Denisova specimen were made. The focus was on non-synonymous mutations, which consequently had an impact on protein levels and...

Fruits as unusual food items of the carnivorous bat Chrotopterus auritus (Mammalia, Phyllostomidae) from southeastern Brazil

We record here the occurrence of seeds of several plant species in feces found inside the day roost of Chrotoperus auritus, at the Estação Experimental de Itirapina, State of São Paulo, Southeastern Brazil, in July 2001. The roost was used by only one adult female, non pregnant, during about a month. In the feces, fur of rodent (Muridae), bone fragments, fragments of Scarabaeidae...

Kisspeptin Stimulation of Prolactin Secretion Requires Kiss1 Receptor but Not in Tuberoinfundibular Dopaminergic Neurons

Kisspeptin has been shown to stimulate prolactin secretion. We investigated whether kisspeptin acts through the Kiss1 receptor (Kiss1r) to regulate dopamine and prolactin. Initially, we evaluated prolactin response in a Kiss1r-deficient mouse line, in which Kiss1r had been knocked into GnRH neurons (Kiss1r−/−R). Intracerebroventricular kisspeptin-10 (Kp-10) increased prolactin...

Relación entre Síntomas Psicóticos, Estados Emocionales Negativos y Años de Evolución en Personas con Esquizofrenia

There is evidence that depression, anxiety and self-esteem are related to the development and maintenance of positive symptoms of psychosis. However, the role of emotion in psychosis is unclear, especially in chronic patients. Method: Twenty patients with a diagnosis of schizophrenia, large illness duration, and persistent delusions and auditory hallucinations were assessed for...

Description of cranial elements and ontogenetic change within Tropidolaemus wagleri (Serpentes: Crotalinae)

Tropidolaemus wagleri is a species of Asian pitviper with a geographic range including Thailand, Vietnam, Malaysia, Singapore, Bruniei, parts of Indonesia, and the Philippines. Tropidolaemus is a member of the Crotalinae subfamily, within Viperidae. The genus Tropidolaemus includes five species, and was once included within the genus Trimeresurus. While some osteologic...

An unusual case of perisplenic small bowel volvulus after laparoscopic Roux En Y gastric bypass

Internal hernias (IH) are one of the dreadful complications of laparoscopic Roux En Y gastric bypass (LGBP). Commonly reported internal hernias (IH) following Roux En Y gastric bypass (LGBP) in the literature are meso-colic, meso jejunal and Peterson’s space hernias. These patients may not have any definitive symptoms. Findings are often missed on radiological studies and a high...

The art of creating futures - practical theology and a strategic research sensitivity for the future

This paper explores a futures perspective for practical theology. Although there are some examples of a future orientation, a systematic futures perspective has not been developed. Building on futures studies (including predictive studies on foresight and design and architecture studies), the authors propose a methodological model for future-sensitive practical theology...

Multi-objective interval prediction of wind power based on conditional copula function

Interval prediction of wind power, which features the upper and lower limits of wind power at a given confidence level, plays a significant role in accurate prediction and stability of the power grid integrated with wind power. However, the conventional methods of interval prediction are commonly based on a hypothetic probability distribution function, which neglects the...

Association analysis uncovers the genetic basis of general combining ability of 11 yield-related traits in parents of hybrid rice

Association analysis between constructed single nucleotide polymorphism linkage disequilibrium blocks (SNPLDBs) and general combining ability (GCA) effects is a novel approach to uncover the genetic basis of GCA within the sequence genomes of parents of hybrid rice. Here, we calculated the GCA effect values of 33 parents of hybrid rice and sequenced them to identify genome-wide...

Parâmetros bioquímicos foliares das espécies Licania tomentosa (Benth.) e Bauhinia forficata (Link.) para avaliação da qualidade do ar

Foliar analysis of biochemical parameters were carried out in order to investigate the influence of air pollutants on two tropical tree species (Licania tomentosa (Benth.) and Bauhinia forfícata (Link.)). Special attention was given to tropospheric ozone due to the fact that concentration levels in the region were found to be up to 140 µg m-3 for a 4 h average time, which is well...

Transverse tendon stiffness is reduced in people with Achilles tendinopathy: A cross-sectional study

Objectives The objective of the current cross-sectional study was to examine Achilles tendon transverse stiffness in a group of recreational runners with Achilles tendinopathy, in comparison to an asymptomatic group of runners with similar training history. We also aimed to determine the between-week intra-individual reliability of this measurement technique. Design Cross...

Consumption of cashew nuts does not influence blood lipids or other markers of cardiovascular disease in humans: a randomized controlled trial

The US Food and Drug Administration (FDA) approved a qualified health claim for tree nuts and reduction of cardiovascular disease. However, cashews are excluded from that claim due to their content of saturated fats, which is predominantly stearic acid. Because stearic acid is neutral with respect to blood lipids, several studies have been conducted to test the effect of cashew...

European postgraduate curriculum in geriatric medicine developed using an international modified Delphi technique

the European Union of Medical Specialists (UEMS-GMS) recommendations for training in Geriatric Medicine were published in 1993. The practice of Geriatric Medicine has developed considerably since then and it has therefore become necessary to update these recommendations.
