A new method for isolating blood leukocytes and measuring intracellular leukocyte magnesium is based on three successive centrifugations (1300 x g, 5 min, 22 degrees C), with no use of Ficoll, followed by two washes. We express the leukocyte magnesium concentration in micromoles of magnesium per gram of protein. Magnesium is measured by atomic absorption spectrophotometry, protein by the classi...

Article history: Received 25 September 2016 Received in revised form 22 March 2017 Accepted 23 March 2017 Available online xxxx The dilute conditions under which microalgae suspensions are cultured have negatively impacted economical routes for cell harvesting using conventional approaches. A promising alternative has arisen, for which a microfluidic concentration approach has been developed fo...

the object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. the evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. the results revealed that the effect of soil moisture content was only significant on...

BACKGROUND The value of newly developed techniques for saphenous vein harvesting remains controversial. Which technique offers the most benefits is still unknown. The aim of this study was to compare the conventional vein harvesting through a continuous skin incision method with 2 less invasive methods and evaluate surgical advantages and postoperative results. METHODS In this prospective stu...

As a foundation for understanding the diet of African savanna elephants (Loxodonta africana), adult bulls and cows were observed over an annual cycle to determine whether harvesting (Pt ), chewing (Ct ) and handling times (Ht ) differed across food types and harvesting methods (handling time is defined as the time to harvest, chew and swallow a trunkload of food). Bulls and cows were observed 1...

BACKGROUND Traditional great saphenous vein harvest for coronary artery bypass grafting is associated with a significant risk of impaired wound healing. Endoscopic saphenous vein harvesting (EVH) has been introduced in an effort to reduce the incidence of leg-wound complications, whereas the histological quality and long-term patency of harvested grafts are comparable with grafts harvested by m...

The most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy. Using piezoelectric cantilevers is the most common method for vibration energy harvesting. Changing the shape of the cantilevers can lead to changing the generated output voltage and power. In this work vibration energy harvesting via piezoelectri...
