A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Towards a reference model for m-commerce over ad hoc wireless networks
Get PDFWireless trading outside established computer networks is an emerging class of mobile application for which there seems to be a growing demand. It enables mobile users to engage wirelessly in online trading regardless of time or location. However, better understanding of the complex issues at stake is needed before effective systems of this kind can be designed and built. Developing a reference model is one way to provide this understanding. M-commerce is defined and its elements, requirements and issues are discussed. The characteristics, functional components, application types, security requirements and issues of ad hoc m-commerce are then analyzed and distinguished
Mesophilic-hydrothermal-thermophilic (M-H-T) digestion of green corn straw
No full textMesophilic-hydrothermal (80-160 degrees C, 30 min)-thermophilic (M-H-T) digestion and control tests of mesophilic (M), thermophilic (T), hydrothermal-mesophilic (H-M), and mesophilic-thermophilic digestion (M-T) of green corn straw were conducted for a 20-day fermentation period. The results indicate that M-H-T is an efficient method to improve methane production. A maximum methane yield of 371.74 mL/g volatile solid was obtained by the M (3 days)-H (140 degrees C)-T (17 days) process, which was 20.44%, 16.55%, 31.44%, and 14.31% higher than the yields of the M, T, 140-M, and M-T processes. The enhanced methane production was attributed to (1) the improved hemicellulose degradation and lignin disorganization; (2) prevention of the degradation of soluble sugar, easily hydrolyzed hemicellulose and cellulose into furfural and methylfurfural; and (3) lack of formation of Maillard reaction products during initial hydrothermal treatment.

Empowering outbound mobility students towards future talents: Universiti Putra Malaysia (UPM) Experience
No full textProviding market-ready talent is challenging. Education needs changes to facilitate the current and future needs of market development in education, a growing and vibrant field. Previous studies have proven that international student mobility is one of the key changes for future education in higher learning institutions. This paper demonstrates the findings of international outbound mobility affecting future employability, career development, and marketability. It is a qualitative study in nature, and the Putra International Centre (i-PUTRA), Universiti Putra Malaysia, has been the chosen institution for this paper. Student Mobility Program provides opportunities and benefits to the students and the institutions. The results indicate that the outbound mobility is enough to maximize benefits for many students. Other factors influencing students to partake in mobility programs include verbal motivation. The study recommends students to enhance their full potential on equipping internationally oriented labor market as global citizen
Contribution of Information and Communication Technology (ICT) in Country’S H-Index
Get PDFThe aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country’s H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country’s H-index is not clear.Cite as:

Lah–Ribarič type inequalities for (h, g; m)-convex functions
No full textRecently introduced new class of (h, g; m)-convex functions unifies a certain range of convexity, thus allowing the generalizations of know results. In this paper we prove Lah–Ribarič type inequalities for (h, g; m)-convex functions from which we obtain inequalities of Hermite–Hadamard, Fejér, Giaccardi, Popoviciu and Petrović. © 2021, The Author(s) under exclusive licence to The Royal Academy of Sciences, Madrid

I bring out his capital immediately
and until such time as their capital
is released things are quite
difficult. "' There are very few
provinces in Canada that will supply
the Dutch settlers with a loan",
Mr. Jensma stated.
On her arrival here Mrs. Evers
i was astounded at the unusua1.
building of the city and the large
• ields of wheat. " Of course we have
wheat too, but ours is only a small
country so we have to be very
economical and not spend out
land too freely". The buildings are
much taller and narrower, especially
in the cities. Wood is very
expensive so most of the homes are
built of brick and concrete with
corrugated steel and tile roofs.
Give True Picture
In her travels across the country
Mrs. Evers hopes she can lenrn
much about the living conditions
here and the possibilities for the
Dutch settlers so when she re-
| turns to her homeland she will b- i
able to give the women of Holland
all the information possible and
prepare them for their great adventure.
Mrs. Evers and her family reside
on a 150 acre farm in the
northern part of the country. Her
daughter Tjaakje is a teacher in
home economics and her son.
Luken, works on the farm.
Besides serving on the immigration
board she is a member of the
international board of the YWCA;
the international Council of Women:
international corporation of
Dutch Country Wives: the international
organization of the Associated
Country Women of thr
World: and a member of the Women's
Institutes.
She will leave on Tuesday for
Toronto, where she will be met by
Mr. W. Blome. who is with the
Netherlands Immigration Board
in Ottawa.
