Nicht die Abwesenheit von Männern, die migriert sind, sondern vielmehr die Ausbreitung des Maisanbaus führt zur Fehl- und Mangelernährung bei den Bemba. Der Maisanbau erhöht die Arbeitsbelastung für Frauen und schränkt die Zeit zur Kinderversorgung ein. (DÜI-Spe)

Describes how problems of food shortages and poor nutrition have been viewed by governments and development planners from the colonial period to the present day. Discusses how perceptions of food problems and the solutions proposed were, and still are, governed by attitudes to the agricultural production system. (PAS)

Fiber-type dye sensitized solar cells that are non-metallic, flexible, and thread-like in structure have many potential military and functional textile applications. With the use of quantum dots (QD), exciton transfer facilitators (Phenyl-C61-butyric acid methyl ester-PCBM) and Poly(3-hexylthiophene-2,5-diyl-P3HT), and careful preparation of the TiO2 oxide layer deposited on the carbon fiber working electrode, an optimized efficiency of 7.6% was obtained. Carbon nanotube yarn (CNTY) was used to prepare both the working and counter electrodes of the fabricated cells. TiCl4 annealing of the TiO2 layer was carried out and the resulting oxide layer morphology was found to be very uniform. The quantum dots, cadmium sulfide (CdS) and cadmium selenide (CdSe), were deposited directly onto the surface of the nanoporous oxide layer using chemical bath deposition (CBD). Also, the P3HT and PCBM were applied and deposited via CBD on the working electrode as a bulk heterojunction material. Potentiometric characterization of the prepared cells performed at different cell lengths and showed that the maximum efficiency was obtained for cells approximately 3.5 cm in length. Photovoltaic performance of these solid state three dimensional cells was also carried out for different cell configurations.

Platelet dysfunction is associated with worsening hemorrhage following brain injury (TBI). Use of antiplatelet medications (APM) is common, especially in elderly patients but the efficacy of platelet transfusion remains unknown. Thrombelastography platelet mapping (TEG-PM) assesses platelet function. We hypothesize that platelet transfusion can reverse the effects of APM but does not improve clinical outcomes in TBI patients on APM. Methods: A 2 year prospective, observational study at 6 US trauma centers was performed. Patients over 17 years old on APM with CT evident TBI after blunt injury were enrolled. Patients underwent TEG-PM and brain CT on arrival and repeat imaging within 24 hours. Platelets were transfused and repeat TEG-PM was ordered at physician discretion. Demographics, platelet transfusion, brain CT and TEG-PM results, length of stay (LOS), and injury severity score (AIS) were abstracted. Groups were compared using student t-test. Results: 66 patients were enrolled (89% aspirin, 34% clopidogrel, 2% ticagrelor). 23 ...
