A unidimensional measure of Hong's Psychological Reactance Scale
No full textResearch using Hong's Psychological Reactance Scale has been fraught with methodological concerns. Researchers have been unable to find a stable, reliable, and replicable factor structure. Here, results suggested that Hong's Psychological Reactance Scale is a unidimensional one with an average alpha of .74 (SD = .46). This value was attained by first analyzing correlation matrices reproduced from three reports on Hong's Psychological Reactance Scale and then verifying this new factor structure with original data. Tests for internal consistency supported a 1-factor solution. Tests for external consistency supported prior findings in relation to Psychological Reactance and offer evidence that the 1-factor solution is externally valid. While the authors contend that a 1-factor solution is appropriate, further testing is needed for external consistency and refinement of the measure. © Psychological Reports 2006

Monoposto racecar wheel aerodynamics: investigation of near-wake structure and support-sting interference
No full textMonoposto racecar development is routinely carried out using wheels supported not by the car
suspension but by individual, externally-mounted stings. The interference effect of these stings
was acknowledged but unquantified in the existing literature. Appraisal of the literature has
found that the structure of a wheel wake was not understood, rendering it difficult to assess the
support sting interference. These two issues were thus jointly addressed using experimental and
computational methods.
The two phases of this project each tested a different industrially-representative racecar wheel
model. Phase One investigated a single wheel and sting combination, whilst Phase Two extended
the work to include two further stings and a model racecar. Non-intrusive velocity measurements
were made in the near wakes of the various combinations to extract vertical planes, perpendicular
to the tunnel freestream.
The measurements made behind the isolated wheels were used to investigate the main flow
features of the wake. The flow surrounding an unsupported wheel was established computationally
and used to evaluate the interference effects of the support sting. Different wheel support
methods (three stings and the car suspension) were used to provide further insight into the sting
interference effects and also the impact of sting design on those effects. Testing with and without
the model racecar allowed evaluation of its effect on the wheel wake and sting interference.
The main characteristics of the near-wake of an isolated wheel rotating in ground contact are
proposed from analysis of the data generated in this study. A simplified model of the trailingvortex
system induced in the wake of such a wheel is proposed to clarify contradictory literature.
The specific interference effects of a wheel support sting are proposed with reference to the main
characteristics of the wake. The mechanisms behind these effects are, where possible, identified
and presented. The main impact of the support sting, and thus the root of several of the observed
effects, is the modification of the axial flow through the wheel.
The main effects of the presence of the car on the near-wake are proposed alongside the observation
that the wake structure is not fundamentally different to that of an isolated wheel. The
proposed sting interference effects are also observed in the presence of the car, albeit at a reduced
level
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:

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

Mr. Jensma stated.
On her arrival here Mrs. Evers
i was astounded at the unusua1.

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.

Catalytic P-H activation by Ti and Zr catalysts
No full textCatalytic dehydrocoupling of phosphines was investigated using the anionic zirconocene trihydride salts [Cp*Zr-2(mu-H)(3)Li](3) (1a) or [Cp*Zr-2(mu-H)(3)K(thf)(4)] (1b), and the metallocycles [CpTi(NPtBu3)(CH2)(4)] (6) and [Cp*M(NPtBu3)(CH2)(4)] (M = Ti 20, Zr 21) as catalyst precursors. Dehydrocoupling of primary phosphines RPH2 (R = Ph, C6H2Me3, Cy, C10H7) gave both dehydrocoupled dimers RP(H)P(H)R or cyclic oligophosphines (RP)(n) (n = 4, 5) while reaction of tBu(3)C(6)H(2)PH(2) gave the phosphaindoline tBu(2)(Me2CCH2)C6H2PH (9). Stoichiometric reactions of these catalyst precursors with primary phosphines afforded [Cp*Zr-2((PR)(2))H][K(thf)(4)] (R = Ph 2, Cy 3, C6H2Me3 4), [Cp*Zr-2((PPh)(3))H] [K(thf)(4)] (5), [CpTi(NPtBu3)(PPh)(3)] (7) and [CpTi(NPtBu3)(mu-PHPh)](2) (8), while reaction of 6 with (C(6)H(2)tBu3)PH2 in the presence of PMe3 afforded [CpTi(NPtBu3)(PMe3)(p(C(6)H(2)tBu(3))] (10). The secondary phosphines Ph2PH and (PhHPCH2)(2)CH2 also undergo dehydrocoupling affording (Ph2P)(2) and (PhPCH2)(2)CH2. The bisphosphines (CH2PH2)(2) and C6H4(PH2)(2) are dehydrocoupled to give (PCH2CH2PH)(2) (12) and (C6H4P(PH))(2) (13) while prolonged reaction of 13 gave (C6H4P2)(8) (14). The analogous bisphosphine Me2C6H4(PH)(2) (17) was prepared and dehydrocoupling catalysis afforded (Me2C6H2P(PH))(2) (18) and subsequently [(Me2C6H2P2)(2)(mu-Me2C6H2P2)](2) (19). Stoichiometric reactions with these bisphosphines gave [Cp*Zr-2(H)(PH)(2)C6H4] [Li(thf)(4)] (22), [Cp*Ti(NPtBu3)(PH)(2)C6H4](2) (23) and [Cp*Ti(NPtBu3)(PH)(2)C6H4] (24).
