A new approach to sample handling for powder X-ray diffraction analysis is presented that allows characterization of poorly prepared samples. The technique relies on vibrations generated in a sample holder to create movement of the powdered sample in the absence of macroscopic movement of the sample holder itself. The major benefits over conventional sample handling strategies are: 1) the abili...

MANY needle-holders are in use and each surgeon has his own preferences for different kinds of suturing, in different kinds of tissues, and in different positions of the surgical field. The position presents a difficult problem and there is often a need for greater accuracy and manoeuverability than is possible with the conventional needle-holders. To meet the need for such an instrument, a "Ho...

Banana production is the mainstay industry for majority of small holder farmers living in mountain regions Kenya. These are affected by climate-related impacts at all levels value chain. This paper therefore discusses climate trends, related impacts, and adaptations banana chain Mt. Kenya region period between 1980 2017. The study locations were purposively selected from to include both Imenti ...

PURPOSE During laparoscopy, as in open surgery, exposure is critical. Here, we describe the use of a laparoscope holder to facilitate the liver lift during urological laparoscopic surgery. MATERIALS AND METHODS Laparoscopic right radical nephrectomy (n = 3), partial nephrectomy (n = 1), and adrenalectomy (n = 2) were performed with 4 ports. At the beginning of the operation, the small snake r...

THE finest movements of surgery are made with the fingers and thumb, not with the wrist and hand as a whole. In the usual method of suturing, the needle is grasped by the needle-holder which is held more or less in the palm of the hand. The fine, sharp needles of ophthalmic surgery, such as those made by Grieshaber, inevitably become dulled as they are grasped by the metal blades of the needle-...

The storage root crop cassava (Manihot esculenta) is the most important source of dietary calories in the tropics after rice and maize [1]. It plays a central role in food and economic security for small-holder farmers and holds unrealized potential as a cash and commodity crop. In Africa, cassava production is constrained by three major diseases: cassava mosaic disease (CMD), cassava brown str...

UNLABELLED To reduce imaging costs, we designed a head holder for scanning two rats simultaneously in small animal PET scanners. Our goals were (i) to maintain high sensitivity and (ii) to minimize repositioning error between scans. METHODS A semi-stereotaxic dual rat head holder was designed and constructed for dual rat scanning in our IndyPET-II scanner and the commercial microPET P4. It wa...
