A Class of Pseudo-Differential Operators Associated with Bessel Operators

AbstractA class of pseudo-differential operators (p.d.o.), generalizing Bessel differential operator d2/dx2 + (1 − 4μ2)/(4x2), is defined. Symbol classes Hm and Hm0 are introduced. It is shown that p.d.o.′s associated with symbols belonging to these classes are continuous linear mappings of the Zemanian space Hμ into itself. An integral representation of p.d.o.′s is obtained. Using Haimo′s theory of the Hankel convolution it is shown that p.d.o.′s satisfy a certain L1 - norm inequality

AbstractAn Lpμ-boundedness result for the pseudo-differential operator associated with the Bessel operator is obtained

Accessing research literature: A mixed-method study of academics in Higher Education Institutions in Nepal

Background: Research in Higher Education (HE), particularly in health and medical sciences plays a crucial role, not only in enhancing knowledge and skills of students and academics, but also in helping to develop managers and policy makers who rely on evidence-based planning and programming. This paper reports university teacher’s knowledge and practices in accessing electronic research-based evidence in health and medical sciences in Nepal. Material and Methods: This was mixed-methods study comprising a self-administered questionnaire completed by HE teachers and informant key interviews with authorities of HE institutions. A total of 15 out of the total 40 institutions offering HE above Bachelors level on health-related subjects were included for the study. Results: The response rate was 68%; 244 out of 360 HE teachers completed self-administered questionnaire. The respondents comprised nurses (36%), followed by doctors (23%), public health practitioners (18%), dentists (17%) and pharmacists (12%). Most of the HE teachers reported that they have computer skills and possess their own computer. Two-thirds (66%) of the HE teachers had work email and almost all (93%) have a personal email ID. All institutions had a computer lab and/or library. Almost all teachers had internet access at work but the internet was reportedly slow. Each institution had a librarian to support to the students and staff but only a third of teachers sought their help. Many do not know what kind of support librarians can provide. Less than half of the staff had accessed electronic research materials. This proportion varied between HE institutions ranging from 13 to 83%. HINARI and PubMed were the mostly used research databases. Less than half of respondents (48%) had published research papers in peer-reviewed journals, and only 19% published a paper based on a systematic review. Female HE teachers were less likely to publish (32%) than males (68%). More readers and professors had published (75%) than instructors/assistant lecturers (30%) and lecturers (45%). Conclusions: Accessing electronic research literature provides an opportunity to gathering up-to-date research-based information that should be core to all health curricula. We call upon curriculum developers and university authorities in Nepal to revise health curricula and help build electronic searching skills among staff and students

A characterization of the spaces S1/k+1k/k+1S^{k/k+1}_{1/k+1} by means of holomorphic semigroups

The Gel’fand–Shilov spaces $\mathfrak{S}_\alpha ^\beta ,{\alpha = 1}/ {(k + 1)},{\beta = k} /{(k + 1)}$, are special cases of a general type of test function spaces introduced by de Graaf. We give a self-adjoins operator so that the test functions in those $\mathfrak{S}_\alpha ^\beta$ spaces can be expanded in terms of the eigenfunctions of that self-adjoins operator

Yield evaluation of a wheat line with combined resistance to russian wheat aphid and stem rust race “Ug99” in Kenya

InKenya, Russian wheat aphid (RWA) and stem rust race TTKS (“Ug99”) are the most devastating pests of wheat. Severe infestations by RWA result in yield losses of up to 90% while epidemics of “Ug99”can cause up to 100% loss. The two pests combined have seriously affected farmer incomes forcing them to rely heavily on pesticides and increasing the cost of production. This study sought to evaluate a wheat line that has been developed to be resistant to both RWA and “Ug99”by pyramiding two major resistance genes. Three varieties were used in this study: “Kwale”, a Kenyan high yielding commercial variety but susceptible to both RWA and “Ug99”; “Cook”, an Australian variety carrying stem rust resistance gene Sr36 conferring immunity to “Ug99”; and “KRWA9”, a Kenyan line resistant to RWA but with poor agronomic attributes. The F1 of the double cross (DC F1) was obtained by crossing the F1 of “Kwale × Cook” and the F1 of “Kwale × KRWA9”. The DC F1 population was subjected to sequential screening for both RWA and “Ug99”resistance. The surviving DC F1 progenies were left to self pollinate in the field to obtain the DC F2. The DC F2 progenies were sequentially screened against RWA and “Ug99”to obtain a resistant population to both RWA and “Ug99”. The yield and yield components of the new resistant line were compared with the three parents. Results showed that the DC F2:3 had higher yields than the three parents based on 1000 kernel weight, weight of kernel per spike, and the actual yield in tons/ha, indicating that the genes were successfully introgressed. It is concluded that though races with virulence for Sr36 have been reported, the gene provides immunity to race “Ug99”and can be used as a component for “Ug99”resistance breeding together with other Sr genes

Gender Identity: Challenges to Accessing Social and Health Care Services for Lesbians in Nepal

Literature about same-sex love and sexuality in Nepal is rare. However, limited anecdotal evidence on these issues signals that the health and social care needs of lesbians in Nepal are high. This qualitative study explores the challenges faced by lesbians in Nepal in accessing health and social services. In-depth interviews carried out with fifteen lesbians found that Nepalese lesbians face many challenges from families and society which result in a stressful life, homelessness and forced and unwanted relationships and marriage, including self-harming behaviours. They often face discrimination and harassment when coming out at public administration and social institutions. Hence, most lesbians of Nepal prefer not to disclose their sexual identity due to the fear of becoming isolated and not getting quality health care services

Youth futures and a masculine development ethos in the regional story of Uttarakhand

Research on the Uttarakhand region, which became a new state in 2000, has focused largely on agrarian livelihoods, religious rituals, development demands, ecological politics and the role of women in regional social movements. This essay discusses another dimension of the regional imaginary—that of a masculine development ethos. Based on ethnographic research and print media sources, this essay focuses on stories, politics, mobilities and imaginations of young men in the years immediately after the achievement of statehood. Despite increased outmigration of youth in search of employment, many young men expressed the dream of maintaining livelihoods in the familiar towns and rural spaces of Uttarakhand, describing their home region as a source of power and agency. In rallies and in print media, young (mostly upper caste) men expressed their disillusionment with the government and the promises of statehood, arguing that their aspirations for development and employment were left unfulfilled. Gendered stories of the region, told in Hindi in rallies and print media, contained references to local places, people and historical events and were produced through local connections and know-how, fostering a regional youth politics. The article argues that Uttarakhand as a region is shaped by the politics of local actors as well as embodied forms of aspiration, affiliation and mobility.IS
