Introduction of emergency contraceptive pills in the public health system of Pakistan: A south-to-south collaboration

This report describes a south-to-south collaboration to assist the Ministry of Health of Pakistan to introduce emergency contraception (EC) into its family planning program, supported by the Population Council’s USAID-funded Frontiers in Reproductive Health (FRONTIERS) program. The collaboration consisted of a three-day visit by senior managers from the Pakistani health authorities to Bangladesh to familiarize them with the EC program in that country, followed by a two-day consultative meeting in Islamabad to draw up concrete plans for introduction of the method into the Pakistan system. Participants at the consultation developed plans to introduce EC into both community-based distribution and clinical programs. The plans included staff training; commodity logistics; and development of information, education, and communication materials, many of which will be adapted from materials used in other EC projects in the region supported by FRONTIERS. The activity successfully met its goals. Providing south-to-south technical assistance was demonstrated to be an effective strategy for introducing sensitive services and is recommended for other regions and similar services

Evaluation of yield performance and establishment methods of drought tolerant rice genotypes under rainfed condition in drought prone areas of Bangladesh

Two field experiments were carried out at farmer’s field of Rajshahi and Chapainawabgonj under the Department of Agronomy, BINA during aman season of 2017 and 2018 consecutively to evaluate the drought tolerant rice varieties under different establishment methods in rain fed condition. First experiment (E1) was conducted to find out the performance of varieties and second experiment (E2) was to find out the suitability of method of transplanting/sowing in combination with short duration aman varieties. Different methods were as direct seeding, puddled and un-puddled transplanting and cultivars were used to cultivate BRRI dhan56, Binadhan-7, Binadhan-17 (except in second experiment) and Huttra (local cultivar). The experiment was laid out in a randomized complete block design with three replications. The recommended fertilizer doses applied for the experiment were 80 kg N ha-1, 15 kg P ha-1, 50 kg K ha-1, 20 kg S ha-1 and 2 kg Zn ha-1. Nitrogen, phosphorus, potassium, sulphur and zinc were supplied from urea, TSP, MoP, gypsum and zinc sulphate monohydrate respectively while urea was applied in three equal splits. Among the cultivar Binadhan-17 produced statistically higher grain yield (5.62 t ha-1) at Chapainawabgonj. Among methods Binadhan-7 statistically higher grain yield 5.32 t ha-1 and 5.21 t ha-1, respectively) in puddle transplanting method both Chapainawabgonj and Rajshahi region during 2017. Among the cultivar Huttra (local) produced statistically higher grain yield (5.43 t ha-1) at Chapainawabgonj. Among methods, BRRI dhan56 statistically higher grain yield 6.37 t ha-1 and 6.19 t ha-1, respectively) in puddle transplanting method bothat Rajshahi and Chapainawabgonj during 2018. Overall results indicates that BRRI dhan56, Binadhan-7, Binadhan-17 performed better in puddled transplanting, Huttra (local) in direct seeding method in drought prone region of Bangladesh

Ambient noise analysis for characterizing sub-surface dynamic parameters

Ambient noise analysis of horizontal to vertical spectral ratio (HVSR) method has been used widely to provide reliable estimates of the site fundamental frequency and to constrain the inversion of near-surface shear wave velocity. The present paper focuses on the site measurement using the aforementioned analysis by means of the HVSR method for characterizing sub-surface dynamic parameters in the City of Banda Aceh, Indonesia. A Guralp CMG-6TD broadband seismometer was used in this study to cover a wide frequency range from 0.033 Hz to 50 Hz in standard operation. The instrument was deployed at two different sites (i.e. Location#1 of Blang Padang and Location#2 of Stadion Dirmutala) in the City of Banda Aceh for at least 2 hours for ambient noise recording. This continuous of 2 hours' microtremor time series was separated into 30 minutes record from which the site fundamental frequency and shear wave velocity of the measured site were deduced. The later sub-surface dynamic parameter was validated using another technique of reflection seismic. This investigation suggests the fundamental frequency of 0.45 Hz at Location#1 and of 0.65 Hz at Location#2. The estimated shear wave velocity of the top 30 m, Vs,30 of this investigation is 165 m/s at Location#1 and 156 m/s at Location#2. Both the site fundamental frequency and shear wave velocity are important for infrastructure design in the high seismic region of Banda Aceh, Indonesia

Analysis of Harvesting Energy from Mistuned Multiple Harvesters with and without Coupling

AbstractEnergy harvesting has received a lot of attention in the recent past. At present a single device does not harvested energy enough to power up an electronic sensors. In order to increase the power output multiple identical harvesters are used. When multiple harvesters are used, they bring in non-uniformity in their physical parameters due to variability during manufacturing or even during deployment. Therefore, ‘n’ numbers of harvesters do not necessary produce ‘n’ times the harvested power of a single device. The variability in parameters is less enough to be coined as mistuning. In this paper, an analysis of multiple energy harvesters is studied. The harvesters are assumed to show mistuning. The study is further extended to understand the effect of mechanical coupling between the harvesters. For simplification, pendulums are considered as the harvesters, with magnetic tip masses for the electromagnetic energy harvesting. Mistuning is achieved by varying the length of the pendulums. A generalized mathematical model for n coupled harvesters with mistuning is developed. Simulations are performed with the number of harvesters varying from 2 to 6 with ±1% non-repetitive mistuning in the lengths of the harvesters, and a comparison of the power harvested between mechanically coupled and uncoupled harvesters is presented

Attitudes and practices of community pharmacists and barriers to their participation in public health activities in Yemen: Mind the gap

Background: Patients in Yemen commonly visit community pharmacies to obtain consultation or treatment for common ailments. Community pharmacists have an opportunity to optimize medication use and improve patient outcomes. This study aimed to evaluate the attitudes and practices of community pharmacists regarding their participation in public health activities and barriers to their participation in these activities. Methods: This cross-sectional study was carried out among community pharmacists working in pharmacies located in urban areas of the Aden governorate of Yemen from March to June 2017 using a self-administered questionnaire. We selected pharmacies from a line list using proportional sampling according to the number of pharmacies in the urban areas of each district. The questionnaire contained four sections: demographic characteristics, attitudes, practices, and barriers encountered. Data were analyzed descriptively, and the Chi-square test was used for analyzing the association of variables (alpha = 0.05). Results: The questionnaire was distributed to 200 community pharmacists working in community pharmacies. Of the 200 respondents, 62% (n = 124) were male. Overall, the mean age (sd) was 30.0 years (8.6) with the number of years of work experience between 2 and 9.9 years (n = 158, 79%). On average, 62.3% of the pharmacists had a positive attitude toward participation in public health activities. Providing education to stop tobacco chewing, smoking, alcohol drinking and improve oral hygiene was an important activity of the community pharmacists. Blood pressure measurements (86%, n = 172) and glucose tests (45%, n = 90) were commonly conducted for clients. Lack of time (71%, n = 142) and lack of teamwork (70%, n = 140) were mentioned as common barriers to participation in public health activities. Conclusions: Community pharmacists had a positive attitude toward public health activities. Health education and routine health tests were important practices of the community pharmacists. Barriers need to be overcome to enable more active participation by community pharmacists in public health activities by consulting with all stakeholders, assessing the situation, considering alternatives and taking action.Scopu

A role for tetraspanin proteins in regulating fusion induced by Burkholderia thailandensis

Burkholderia pseudomallei is the causative agent of melioidosis, a disease with high morbidity that is endemic in South East Asia and northern Australia. An unusual feature of the bacterium is its ability to induce multinucleated giant cell formation (MNGC), which appears to be related to bacterial pathogenicity. The mechanism of MNGC formation is not fully understood, but host cell factors as well as known bacterial virulence determinants are likely to contribute. Since members of the tetraspanin family of membrane proteins are involved in various types of cell:cell fusion, their role in MNGC formation induced by Burkholderia thailandensis, a mildly pathogenic species closely related to B. pseudomallei, was investigated. The effect of antibodies to tetraspanins CD9, CD81, and CD63 in MNGC formation induced by B. thailandensis in infected mouse J774.2 and RAW macrophage cell lines was assessed along with that of recombinant proteins corresponding to the large extracellular domain (EC2) of the tetraspanins. B. thailandensis-induced fusion was also examined in macrophages derived from CD9 null and corresponding WT mice, and in J774.2 macrophages over-expressing CD9. Antibodies to CD9 and CD81 promoted MNGC formation induced by B. thailandensis, whereas EC2 proteins of CD9, CD81, and CD63 inhibited MNGC formation. Enhanced MNGC formation was observed in CD9 null macrophages, whereas a decrease in MNGC formation was associated with overexpression of CD9. Overall our findings show that tetraspanins are involved in MNGC formation induced by B. thailandensis and by implication, B. pseudomallei, with CD9 and CD81 acting as negative regulators of this process
