IJERPH, Vol. 14, Pages 721: Access to HIV Care and Resilience in a Long-Term Conflict Setting: A Qualitative Assessment of the Experiences of Living with Diagnosed HIV in Mogadishu, Somali

05-Jul-2017 | Kulane, Asli ; Owuor, John O. A.; Sematimba, Douglas ; Abdulahi, Sacdia Abdisamad; Yusuf, Hamdi Moalim; Mohamed, Lul M., International Journal of Environmental Research and Public Health, 2017

Background: Human Immunodeficiency Virus (HIV) continues to take a heavy toll on the lives of many people, with the worst impact on health and wellbeing for the affected individuals in fragile states. The HIV situation in Somalia is not clearly known and experiences of the people living with HIV ...


Functional Nano-Dispensers (FNDs) for In Vivo Delivery of Pesticides against Psyllids

07-Jul-2015 | W L Meyer; Pablo Gurman; Lukasz Stelinski; Noel Elman, Green Chemistry, 2015

Imidacloprid is a widely used insecticide against a variety of vectors. Imidacloprid may have a negative environmental impact, and toxic effects to animals and humans. In this work, we present Functional Nano-Dispensers (FNDs), based on polymeric encapsulation of imidacloprid, using poly ...


Effectiveness of Chlorine Dispensers in Emergencies: Case Study Results from Haiti, Sierra Leone, Democratic Republic of Congo, and Senegal

06-Apr-2015 | Travis M. Yates; Elise Armitage; Lilian V. Lehmann; Ariel J. Branz; Daniele S. Lantagne, Environmental Science & Technology, 2015

Dispensers are a source-based water quality intervention with promising uptake results in development contexts. Dispenser programs include a tank of chlorine with a dosing valve that is installed next to a water source, a local Promoter who conducts community education and refills the Dispenser, ...


Selenium-Containing N-Heterocyclic Carbenes and Their First Palladium(II) Complexes: Synthesis, Structure, and Pendent Alkyl Chain Length Dependent Catalytic Activity for Suzuki–Miyaura Coupling

10-Apr-2013 | Kamal Nayan Sharma; Hemant Joshi; Alpesh K. Sharma; Om Prakash; Ajai K. Singh, Organometallics, 2013

Three new N-alkyl-N′-(2-ethyl-1-selenophenyl)imidazolium salts, L1–L3 (differing in the chain length of alkyl substituent of N), which are precursors to (Se, CNHC) ligands and their N-heterocyclic carbene (NHC) complexes [Pd(L-HX)Cl2] (1–3) [L = L1–L3, X = I/Br], have been synthesized and ...


Characterization of alkali metal dispensers and non-evaporable getter pumps in ultrahigh vacuum systems for cold atomic sensors

09-Oct-2012 | David R. Scherer, David B. Fenner, and Joel M. Hensley, Journal of Vacuum Science & Technology B, 2012

A glass ultrahigh vacuum chamber with rubidium alkali metal dispensers and nonevaporable getter pumps has been developed and used to create a cold atomic sample in a chamber that operates with only passive vacuum pumps. The ion-mass spectrum of evaporated gases from the alkali metal dispenser has ...


A 3D Tumor Spheroid Chip with the Pharmacokinetic Drug Elimination Model Developed by Balanced Droplet Dispensing

10-Sep-2012 | Taeyoon Kim, Il Doh, Young-Ho Cho, Sensors and Actuators B: Chemical, 2012

This paper presents a three-dimensional (3D) tumor spheroid chip where the pharmacokinetic (PK) drug elimination model is developed by balanced droplet dispensing. The PK model should reflect the exponential decrease of drug concentration in a body to improve the reliability of cell-based ...


Sex Pheromone Components and Control of the Citrus Pock Caterpillar, Prays endocarpa, Found in the Mekong Delta of Vietnam

20-Nov-2010 | Le Van Vang, Nguyen Duc Do, Le Ky An, Pham Kim Son, Tetsu Ando, Journal of Chemical Ecology, 2010

The citrus pock caterpillar, Prays endocarpa (Yponomeutidae; Praydinae), is a pest of pomelo (Citrus grandis L.) in Vietnam. Gas chromatography-mass spectrometry analyses of pheromone gland extracts from female moths identified three monoenyl compounds, (Z)-7-tetradecenal (Z7-14:Ald), ...


Effect of Pheromone Dispenser Density on Timing and Duration of Approaches by Peachtree Borer

03-Sep-2010 | Luís A. F. Teixeira, Matthew J. Grieshop, Larry J. Gut, Journal of Chemical Ecology, 2010

The timing and duration of approaches by male peachtree borer Synanthedon exitiosa Say (Lepidoptera: Sesiidae) to commercial pheromone dispensers placed singly or at high density in peach orchards was determined by using field-deployed video cameras and digital video recorders. Cameras were ...


Autolabo: an automated system for ligand‐soaking experiments with protein crystals

01-Aug-2010 | ; Michihiro Sugahara; Katsumi Shimizu; Yukuhiko Asada; Hideki Fukunishi; Hirohumi Kodera; Takeshi Fujii; Eiji Osada; ..., Journal of Applied Crystallography, 2010

Ligand soaking of protein crystals is important for the preparation of heavy‐atom derivative crystals for experimental phasing as well as for large‐scale ligand screening in pharmaceutical developments. To facilitate laborious large‐scale ligand screening, to reduce the risk of human contact with ...


Identification and Field Activity of a Male-Produced Aggregation Pheromone in the Pine Sawyer Beetle, Monochamus galloprovincialis

01-May-2010 | Juan A. Pajares, Gonzalo Álvarez, Fernando Ibeas, Diego Gallego, David R. Hall, Dudley I. Farman, Journal of Chemical Ecology, 2010

The pine sawyer beetle, Monochamus galloprovincialis, is a pest of pine trees in Europe and North Africa. Previously considered a secondary pest of stressed and dying trees, it is now receiving considerable attention as a vector of the pine wood nematode, Bursaphelenchus xylophilus, the causal ...
