"You’re in the boxing ring and it’s just the two of you and it’s sort of survival" - The quest for excitement in professional female Muay Thai boxing
Full text linkUsing a figurational sociological approach, this research analyses the motivations of professional female Muay Thai boxers in training and competition, and ways in which they negotiate their elite status in a male-associated sport. To do this, I draw on fourteen semi-structured interviews to analyse the extent to which females in Muay Thai experience a quest for excitement. It is suggested females are motivated to participate as the sport acts as an emotional and physical outlet and is used as a means to gain mimetic satisfactions which men have originally acquired through sports. The participants in this study experienced pleasurable, de-routinising satisfactions associated with taking part in an activity that is considered male-dominated and masculine. Female Muay Thai boxers’ experiences of the quest for excitement also incorporate a desire for gender equality by resisting traditional female roles which are often more routinised, and feminine-appropriate sports which can lack in physical contact. Although they experienced enjoyment through their involvement in a male-associated sport, participants often placed emphasis on their femininity to counteract their success. Overall it is argued females can experience a specifically gendered quest for excitement in Muay Thai which differs to men’s experiences. This research supplements the minimal existing research on females in martial arts and serves as a comparison to literature on men’s and women’s experiences of the quest for excitement

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
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
Full text linkFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
[[alternative]]Bioactivities of Synthetic All-D and All-L Mastoparan M
No full text[[abstract]]Mastoparan M, a tetradecapeptide toxin (INLKAIAALAKKLL-NH2) from the hornet venom, and its D-antipot mastoparan M have been synthesized chemically in this experiment . Under circular dichroism investigation, all D- and L-mastoparan M adopted 28% α-helical structure in the 30% trifluroethanol solution but contained only 10% α-helical structure in the phosphate solution. After addition of mastoparan M to the cultures of tumor cell lines in vitro, D-mastoparan M(12.5 μg/ml) could directly inhibit the growth of tumor cell lines Colo 225 (59%), KB (38%), Hep-2 (63%), H226Br (43%) and HeLa (54%) determined by the MTT assay. We also found that the D-mastoparan M has a higher potency of antitumor cell activity in vitro than L-mastoparan M. Examination under the scanning-beam electron microscope (SEM), the hollow, shrunk, and collapsed structures of tumor cells can be seen after mixed with D-mastoparan M. The appearance of these morphological alterations indicated that the mastoparan M inhibited liability of tumor cells by lysis of target cells directly.
All-D mastoparan M could also cause 3H-thymidine releasing from the labeled bacterial population after mixing for 1 h and completed cell lysis by 4 h. We found that both L- and D- mastoparan M all showed strong activity against both the gram-positive and gram-negative bacteria. Especially, the all-D mastoparan M possesses the highest potency of antibacterial activity about two fold more potent than the L-mastoparan M. The effects of all-D mastoparan M on the surface morphology of Staphylococcus aureus (ATCC 29213) and Escherichia coli (ATCC 25922) were studied by the scanning-beam electron microscope (SEM). We found that small "bleb" extrusions on the surface of some S. aureus and "swelling" on the end site of E. coli after cultured with all-D mastoparan M. This finding indicated the all-D mastoparan M could kill bacteria by disrupting cells directly.
Besides lytic tumor cells and bacteria, mastoparan M could also stimulate immune response. After addition of mastoparan M to the culture of mouse macrophage in vitro, tumor necrosis factor-α (TNF-α) and interleukin 1β (IL-Iβ) were detectable in the culture fluids after 12 h and the highest accumulation were observed at 24 h. Mastoparan M induced an increase in TNF-α secretion and in mRNA level at the same time. The nitrite level, reflecting the nitric oxide synthesis, was also accumulated in the culture of macrophages at 24 h post-mastoparan M addition. In vivo studies showed that mastoparan M induced the formation of TNF-α, IL-1β, and nitrite in the peritoneal exudates of mouse much faster at 90 min, 120 min, and 180 min post-mastoparan M injection respectively. Similarly, significant increases in activity to a high level of myeloperoxidase, a marker for neutrophil and macrophage content, were observed among the peritoneal lavage cells after intraperitoneal injection of mastoparan M. However, induction of nitrite by mastoparan M was completely inhibited by simultaneous addition of anti-mouse TNF-α antibody to the cultures of macrophage. These results suggest that modulation of both neutrophils and macrophages influx by mastoparan M was conveyed through TNF-α and IL-1β secretion accompanied with nitrite formation.

Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
Measurement of the branching fractions for B--> D(*)+pi(-)l(-)(nu)over-bar(l) and (B)over-bar(0)-> D-(*)0 pi(+)l(-)(nu)over-bar(l)
No full textWe report on a measurement of the branching fractions for B- --> D(*)+ pi(-)l(-)(nu) over bar (l) and (B) over bar (0) --> D-(*)0 pi(+)l(-)(nu) over bar (l) with 275 x 10(6) B (B) over bar events collected at the Y(4S) resonance with the Belle detector at KEKB. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We obtain B(B- --> D(+)pi(-)l(-)(nu) over bar (l)) = (0.54 +/- 0.07 (stat) +/- 0.07(syst) +/- 0.06(BR)) x 10(-2), B(B- --> D*+pi(-) l(-) (nu) over bar (l)) (0.67 +/- 0.11 (stat) +/- 0.09(syst) +/- 0.03(BR)) x 10(-2), B((B) over bar (0) --> D(0)pi(+)l(-) (nu) over bar (l)) = (0.33 +/- 0.06(stat) +/- 0.06(syst) +/- 0.03(BR)) x 10(-2), B((B) over bar (0) -->D(*0)pi(+)l(-)(nu) over bar (l)) = (0.65 +/- 0.12(stat) +/- 0.08(syst) +/- 0.05(BR)) x 10(-2), where the third error comes from the error on (B) over bar --> D((*))l(-)(nu) over bar (l) decays. Contributions from B-0 --> D(*+)l(-)(nu) over bar (l) decays are excluded in the measurement of (B) over bar (0) --> D(0)pi(+)l-(nu) over bar (l).Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)0ARTICLE5null7

The stability of IQ in people with low intellectual ability: an analysis of the literature
Full text linkA meta-analysis of the stability of low IQ (IQ 80) was performed on IQ tests that have been
commonly used—tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997)
and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-
mean stability coefficients of .77 and .78 were found for Verbal IQ (V IQ) and Performance IQ
(P IQ) on the Wechsler tests and .82 for Full-Scale IQ (FS IQ) on both Wechsler and Binet tests,
for a mean test–retest interval of 2.8 years. Although the majority of FS IQs changed by less than
6 points, 14% changed by 10 points or more. The author suggests that the results of IQ assessment
should be treated with more caution than previously thought
