In this paper I evaluate the merit of costly signaling theory (CST) as a paradigm for understanding why men of Ifaluk atoll torch fish. I argue that torch fishing is a handicap that signals men’s productivity. Consistent with CST, torch fishing is observed by the predicted audience (women), energetically costly to perform, and a reliable indicator of the frequency a man fishes during the trade ...

introduction:torch infections causing via toxoplasma gondii, other microorganisms (e.g., treponema pallidum), rubella virus, cytomegalovirus (cmv) and the herpes simplex virus (hsv) types 1 and 2 during the first trimester of pregnancy can lead to severe fetal anomalies or even fetal loss. the current study determined the serological data of torch infections in women who were in their first tri...

One walking a dark maze may stumble upon a wholesome thing but also may hurt his brow there. Another one takes a small torch at least to throw light upon the darkness. And as he walks, his torch will kindle more and more brightly, turning itself into an electric sun at one moment to elucidate and clarify all around him. Thus, I ask you where is your torch? Dmitry Mendeleev, the author of the ch...

The Olympic flame and torch are significant symbols of the Olympic Games and are important in linking the general public with the festival. They are internationally recognized symbols, particularly important at the Opening and Closing Ceremonies. “It is through the opening and closing ceremonies and the torch relay that the Olympiad must distinguish itself from another series of world champions...

BACKGROUND The dramatic increase in use of the IgG test for toxoplasma, rubella, cytomegalovirus (CMV), and herpes simplex virus (HSV) [TORCH] has led to the requirement for a high-efficiency method that can be used in the clinical laboratory. This study aimed to compare the results of BGI-Array ELISA TORCH IgG (BGI-GBI, China) screening method to those of Virion/Serion TORCH IgG ELISA (Virion/...

The effectiveness and mechanism of a low temperature air plasma torch in clotting blood are explored. Both blood droplets and smeared blood samples were used in the tests. The treated droplet samples reveal how blood clotting depends on the distance at which the torch operated, and for how long the droplets have been exposed to the torch. Microscopy and cell count of smeared blood samples shed ...

Welding fumes are classified as Group 2B 'possibly carcinogenic' and this prompts to the implementation of local exhaust ventilation (LEV). The fume extraction torch with LEV integrated into the tool is the most attractive solution but its capture efficiency is often disappointing in practice. This study assesses the main parameters affecting fume capture efficiency namely the extraction flow r...
