    Microfranchising has emerged as a potential strategy to rapidly scale up entrepreneurship within base of the pyramid (BOP) markets in order to contribute to poverty reduction and to increase economic growth. However, we know little about how such networks are designed and orchestrated in resource-scarce settings to co-create value with the different parties involved. To address this gap, we report a longitudinal case study of an emerging microfranchise network social enterprise, currently facilitated by CARE, a global humanitarian and development organization, to provide timely access to quality, affordable agricultural input and services for millions of small-scale poor farmers in Bangladesh. We draw on the orchestration of innovation network theory developed by Dhanaraj and Parkhe (2006) and the notion of network imprinting (Marquis and Tilcsik, 2013) to analyze the emerging microfranchise network in Bangladesh. As a result, we offer two types of contributions to theory and to practice. First, we offer a detailed account of how these theories are relevant and applicable to analyze and explain the emergence of microfranchise networks, and we present two key propositions to generalize to theory. Furthermore, we propose an integrated framework, combining the two theories for scholars and practitioners interested in designing innovation networks. Second, based on these empirical results and extant theory, we offer three main lessons for practitioners to advance the industry by designing and orchestrating microfranchise innovation networks in embedded contexts to achieve positive financial and social impacts

    2, 4-Dimethyl-6-hydroxyacetophenone oxime and 3, 5-dibromo-2, 4-dimethyl-6- hydroxyacetophenone oxime as reagents and diethylamine as a synergist in the extraction and separation of metals

    1022-10242,4-Dimethyl-6-hydroxyacetophenone oxime and 3,5- dibromo-2,4-dimethyl-6-hydroxyacetophenone oxime act as very good reagents for the extraction and separation of Cu(II), Ni(II), Co(II), Fe(III) and Mn(II). Addition of diethylamine as a synergist in the extraction system, not only increases the per cent extraction of the metals but also the molar absorbances of the complexes. The separation of the metals from one another, viz., Cu(II) from Ni(II), Cu(II) from Co(II) and Cu(II) and Ni(II) from Cr(III) becomes far more easier in the presence of diethylamine

    This study aims to increase the students\u27 comprehension of the concept of hydrostatic pressure and the law of Archimedes through discovery learning. The subjects of the study were VIII-A SMPK Citra Bangsa Kupang, Province of East Nusa Tenggara in the academic year 2016/2017. The data of this study consisted of quantitative and qualitative data. The instruments used in the study were pretest and posttest in the form of reasoned multiple choice. The result of data analysis of concept comprehension showed that the posttest average score was 83.33 and it was greater than the pretest score that achieved 46.66. The calculation of d-effect size was 2.73 (very high category) and N-gain was 0.69 (medium category). Thus, it is concluded that the discovery learning model has a positive impact on the improvement of concept comprehension.Penelitian ini bertujuan meningkatkan pemahaman konsep tekanan hidrostatis dan hokum Archimedes siswa melalui pembelajaran discovery.

    A Compartive Clinical Study of therapeautic effect of Rambana Rasa with and without Eranda Sneha in Amavata w.s.r. Rheumatoid Arthritis

    Amavata is the most challenging disease for the medical science, as it causes severe intolerable pain and severe deformities making the patient disable and bed ridden. As it is the disease of Rasavaha Srotas and having several features similar to Rheumatoid Arthrtis, Amavata can be co-related with Rheumatoid Arthritis (RA). Ama and vitiated Vata play dominant role, though all Dosha take part in the causation of the disease, Amavata is the outcome of Agnidushti, Amotpatti and Sandhivikruti, with the passage of the time most of the dietary habits, changing lifestyle and environment have been contributing to the disease, the risk factor include age, gender, genetics and environmental exposure. Worldwide, the annual incidence of RA is approximately 1%, increasing with age and peaking between the age of 35 and 50 years. So, patients are continuously looking for the treatment from Ayurveda to overcome this challenge. Ramban Rasa is unique formulation which is favorable in the management of the Amavata, as mentioned by Yogratnakar, Bhaishajya Ratnawali, Bhav Prakash and other classical text

    NO2 and Humidity Sensing Characteristics of Few-layer Graphene

    Full text link
    Sensing characteristics of few-layer graphenes for NO2 and humidity have been investigated with graphene samples prepared by the thermal exfoliation of graphitic oxide (EG), conversion of nanodiamond (DG) and arc-discharge of graphite in hydrogen (HG). The sensitivity for NO2 is found to be highest with DG. Nitrogen-doped HG (n-type) shows increased sensitivity for NO2 compared to pure HG. The highest sensitivity for humidity is observed with HG. The sensing characteristics of graphene have been examined for different aliphatic alcohols and the sensitivity is found to vary with the chain length and branching.Comment: 19 pages, 7 figure

    Stable Field Emission from Layered MoS2 Nanosheets in High Vacuum and Observation of 1/f Noise

    Get PDF
    Field emission and current noise of hydrothermally synthesized MoS2 nanosheets are investigated in ultra-high-vacuum and industrially suited high-vacuum conditions. The study reveals that the emission turn-on field is pressure dependent. Moreover, the MoS2 nano‐sheets exhibit more stable field-electron emission in high- vacuum than in ultra-high-vacuum conditions. The investigations on field-emission current fluctuations show features of 1/f-type noise in ultra-high-vacuum and high-vacuum conditions, attributed to adsorption and desorption processes. The post-field-emission results indicate the MoS2 nanosheets are a robust field emitter in high-vacuum conditions

    Effect of continuous light on spermatogenesis and testicular steroidogenesis in rats: Possible involvement of alpha 2u-globulin

    Get PDF
    ABSTRACT Male rats exposed to continous light for 70days showed an increased weights of testis, accessory sex organs, serum levels of FSH, LH, testosterone, testicular 17β-hydroxysteroid dehydrogenase (17β-HSD) activity and alpha 2u-globulin, while 3β-hydroxysteroid dehydrogenase activity showed no signifi cant changes. Prolonged light exposure also stimulated sepermatogenesis in rats. These results suggest that alpha 2u-globulin possibly stimutates the male gonad by inducing pituitary gonadotropins in continuous light-exposed rats. Keywords: Constant light, alpha 2u-globulin, testis. urine. HORMONE ASSAY Serum FSH and LH were measured by radioimmunoassay according to the method of Moudgal and Madhwa Raj
