When Patrick Eze moved to Lagos, Nigeria, he was determined to find a better life; that would mean he needed a secure and reliable job. When the opportunity to work for Washaman drycleaners presented itself, inexperienced Eze took on training and worked his way up in the company until he...
with one notable finding revealing that biomarkers from dry cleaners had significant micronuclei frequency and DNA damage, even when exposed to PCE at levels below occupational exposure limits. Similarly, another study supported these results, finding an increase in early DNA ...
However, despite the previous design scheme when xGk = 0, the following equality Q2 = Q1 takes place under a specific value of the angle αc. Therefore, the problem of equality for the clutch margins has been solved. Figure 9 shows results on changes in the forces Q1(α1) and Q2(α2...
This friction takes place between the chip and the wall of the hole, and between the chip and the flute of the drill. The friction increases when larger chips are formed. The chip compresses like a spring in the flute, and the more it is compressed, the larger the friction. The ...
From 1906 to 1934 he was professor of geography at the University of Munich. In 1910 he took part in the expedition of Ferdinand, Count von Zeppelin, to the Arctic island of Spitsbergen (now Svalbard), north of Norway, where he studied the influence of glaciers on land features. With Fri...
The LMD process, due to its highly localized deposition nature, allows for the addition of the right material at the right place for components with different degrees of geometrical complexity [5]. The process can produce parts with almost 100% density and reliable metallurgical properties that ...
The cyclone separator-sublimator is expected to be used in place of the conventional evaporator in the CO2 heat pump system. A prototype acrylic cyclone separator-evaporator with a heat storage tank was constructed, and dry ice particle collection efficiency and temperatures were measured using a ...
Another way to reduce milk production in dairy cows is to move the cows to another place during drying-off to make restrictive feeding easier. Moreover, the stress associated with such routine may further reduce milk production [2,15,19]. In line with this, the national recommendation valid ...
The uncontrolled mating often took place at communal grazing. Farmers that had low knowledge about effects of inbreeding used their own bulls as long as possible, allowing them to mate with close relatives. They perceived that mating of related animals has no problem on productive and reproductive...
The study of tropical tropospheric disturbances has led to important challenges from both observational and theoretical points of view. In particular, the observed wavenumber-frequency spectrum of tropical oscillations has helped bridge the gap between observations and the linear theory of equatorial waves...
