Background: human African trypanosomiasis (hAT) occurs in three historical foci in the Central African Republic. Objective: To describe the morbi-mortality of childhood hAT in rural Central African Republic with the aim of early management. Methods: Descriptive and analytic cross-sectional study conducted from January 1, 2017 to March 30, 2018 at Nola prefectural hospital. This study was included all children seen as outpatients and/or hospitalized in the pediatric wards, in whom the diagnosis of hAT was confirmed. Statistical analysis was performed using Epi-info software. Results: Forty children were included from Bilolo (60%), Nola (30%) and Salo (10%). The sex ratio was 0.66 with a median age of 8.65 ± 12.48 years. Fever (82.5%), nocturnal insomnia (75%), daytime somnolence (67.5%), headache (65%), polyarthralgia (62.5%), convulsions 52.5% (n = 21), tremor (27.5%), trypanidism (7.5%) and delirium (2.5%) were the main functional signs. Examination signs were adenopathy (52.5%), paresthesia (30%), decreased cutaneous-abdominal reflexes (25%) and osteoarticular reflexes (17.5%), hyperesthesia (20%), extrapyramidal hypertonia (15%) and depression (2.5%). The children were in the lymphatic-blood phase in 65% of cases, and meningoencephalitis in 35%. Pentamidine was administered in 65% of cases. Four children died and 6 had neurological sequelae. There was an association between age under 5, Bilolo’s focus, the children’s history and the severity of the disease. Age under 5, gender, household, children’s activity, history and occurrence of sequelae were also associated. Conclusion: hAT remains a permanent threat to Central African children. Any clinical presentation combining long-term infectious signs and unexplained neurological or neuropsychological disorders must be treated with caution.

Chinese Optics Letters 2008年第10期6卷 748-754页

作者： sonny Vo James S.harris Solid State and Photonics Laboratory Stanford UniversityStanfordCalifornia94305USA

This paper reviews the progress on nano-aperture vertical-cavity surface-emitting lasers （VCSELs）. The design, fabrication, and polarization control of nano-aperture VCSELs are reviewed. With the nanoaperture evolving from conventional circular and square aperture to unique C-shaped, h-shaped, I-shaped, and bowtie-shaped aperture, both the near-field intensity and near-field beam confinement from nanoaperture VCSELs are significantly improved. As a high-intensity compact light source with sub-100- nm spot size, nano-aperture VCSELs are promising to realize many new near-field optical systems and applications.

Globally,cocoa is famous for the production of chocolates and ***,it also serves as a source of raw material for the manufacturing of high-quality cosmetic and pharmaceutical products. Due to its high demand,cocoa is regarded as a major commodity for poverty alleviation in deprived cocoa farming communities. Government has therefore instigated relevant measures to address issues facing the sector by investing in extension programs. These programs act as information dissemination tools for teaching modern farming technologies and enhancing learning among farmers. This study highlighted the effects of the Cocoa Life Project (CLP) by Cooperative for Assistance and Relief Everywhere (CARE) International on farm productivity and income of 200 cocoa farmers in three districts of the Eastern Region,Ghana. Regression on covariates,heckman’s treatment effects model,and propensity scores were used to test the robustness of the estimates. A positive association between extension program participation,farm productivity,and household income was discovered. Specifically,after correcting for selection bias,the estimated results of the heckman’s model showed that the extension program significantly increased participating farmers’ cocoa yield by 14.3%. The effects on total farm income showed a significant increase of 25.1 and 42.9%,respectively from regression on propensity scores and the heckman’s model. Across all three models,program participation led to an increase in total household income by 46.1,31.7,and 69.3%,respectively. Other variables such as farming characteristics,institutional and demographic factors affected farmers’ income,depending on the estimation method used. This study reiterated the supporting role played by extension programs in enhancing cocoa production and increasing household income in Ghana. Conclusively,government and development partners should invest in extension programs by providing enough logistics,training qualified agents,and creat

Journal of Flow Control, Measurement & Visualization 2014年第1期2卷 18-23页

作者： Seyed Mohammad hasheminejad hatsari Mitsudharmadi sonny handojo Winoto Department of Mechanical Engineering National University of Singapore Singapore Temasek Laboratories at National University of Singapore Singapore

The use of leading edge with different geometrical patterns will affect the development of boundary layer flow on a flat plate and its heat transfer properties. In this work, the effects of three patterns namely saw-tooth, semicircular and slots with same wavelength and amplitude were examined. The experiments were carried out for Reynolds number based on wavelength of patterns ranging from 1540 to 3850. For all cases, after each valley, an oval shape region was formed containing a counter- rotating vortex pair. It is also shown that for the flat plate with slots, another vortex was visualized between each valley.

AIM To correlate the length of endoscope hang time and number of bacteria cultured prior to *** Prospectively, we cultured specimens from 19 gastroscopes, 24 colonoscopes and 5 side viewing duodenoscopes during the period of 2011 to 2015. A total of 164 results had complete data denoting date of cleansing, number of days stored and culture results. All scopes underwent initial cleaning in the endoscopy suite utilizing tap water, and then manually cleaned and flushed. high level disinfection was achieved with a Medivator~? DSD(Medivator Inc., United States) automated endoscope reprocessor following manufacturer instructions, with Glutacide~?(Pharmax Limited, Canada), a 2% glutaraldehyde solution. After disinfection, all scopes were stored in dust free, unfiltered commercial cabinets for up to 7 d. Prior to use, all scopes were sampled and plated on sheep blood agar for 48 h; the colony count was obtained from each plate. The length of endoscope hang time and bacterial load was analyzed utilizing unpaired t-tests. The overall percentage of positive and negative cultures for each type of endoscope was also calculated. RESULTS All culture results were within the acceptable range(less than 200 cfu/mL). One colonoscope cultured 80 cfu/mL after hanging for 1 d, which was the highest count. ERCP scopes cultured at most 10 cfu, this occurred after 2 and 7 d, and gastroscopes cultured 50 cfu/mL at most, at 1 d. Most cultures were negative for growth, irrespective of the length of hang time. Furthermore, all scopes, with the exception of one colonoscope which had two positive cultures(each of 10 cfu/mL), had at most one positive culture. There was no significant difference in the number of bacteria cultured after 1 d compared to 7 d when all scopes were combined(day 2: P = 0.515; day 3: P = identical; day 4: P = 0.071; day 5: P = 0.470; day 6: P = 0.584; day 7: P = 0.575). There was also no significant difference in the number of bacteria cultured after 1 day compared
