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
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.

Contribution of Information and Communication Technology (ICT) in Country’S H-Index
No full textThe 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:

Model-independent extraction of {pipe}Vtq{pipe} matrix elements from top-quark measurements at hadron colliders
No full textCurrent methods to extract the quark-mixing matrix element {pipe}Vtb{pipe} from single-top-production measurements assume that {pipe}Vtb{pipe}>>{pipe}Vtd{pipe},{pipe}Vts{pipe}: top quarks decay into b quarks with 100 % branching fraction, s-channel single-top production is always accompanied by a b quark and initial-state contributions from d and s quarks in the t-channel production of single top quarks are neglected. Triggered by a recent measurement of the ratio, 0. 90 ±0. 04 performed by the D0 collaboration, we consider a {pipe}Vtb{pipe} extraction method that takes into account non zero d- and s-quark contributions both in production and decay. We propose a strategy that allows to extract consistently and in a model-independent way the quark-mixing matrix elements {pipe}Vtd{pipe}, {pipe}Vts{pipe}, and {pipe}Vtb{pipe} from the measurement of R and from single-top measured event yields. As an illustration, we apply our method to the Tevatron data using a CDF analysis of the measured single-top event yield with two jets in the final state, one of which is identified as a b-quark jet. We constrain the {pipe}Vtq{pipe} matrix elements within a four-generation scenario by combining the results with those obtained from direct measurements in flavor physics and determine the preferred range for the top-quark decay width within different scenarios. © 2012 Springer-Verlag / Società Italiana di Fisica
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.
