Criminal anthropology of mariticide in Russia. Foreword to the article by P.N. Tarnovskaya “Female criminality in connection with early marriages”
No full textObjective: to provide a general overview of the content of P.N. Tarnovskaya’s article “Female criminality in connection with early marriages”, to determine its place in its author’s heritage and its scientific value for modern criminology.Methods: the general scientific method of dialectical cognition, comparison, as well as the formal logical method (deduction, induction, definition and division of concepts).Results: having analyzed the content of P.N. Tarnovskaya’s article, the author determined its significance as the initial stage of forming her anthropological concept in the study of female murderers. The author specified the sections of P.N. Tarnovskaya’s monograph “Women-murderers” (1902), which use the results of the research described in the article under study. The author refuted the opinion, previously prevailing in Russian criminology, that anthropological research by P.N. Tarnovskaya was supposed to use biological means to prevent crime. On the contrary, in this work Tarnovskaya recommended changing the social environment to curb female criminality (mariticide), namely, abandoning the widespread early marriages of adolescent women before the end of puberty.Scientific novelty: for the first time, the author gives a criminological assessment of P.N. Tarnovskaya’s article “Female criminality in connection with early marriages” and indicates its links with her subsequent works.Practical significance: the results obtained make it possible to change the perception of research by P.N. Tarnovskaya’s as one of the founders of world criminological science. In her concept of crime prevention, the impact on general social factors on female criminality was considered fundamental for the prevention of women’s deviant behavior
Voltammetry and determination of metronidazole at a carbon fiber microdisk electrode
No full textThe electrochemistry of metronidazole, 1-(hydroxyethyl)-2-methyl-5-nitroimidazole, was investigated at a carbon fiber microdisk electrode in pH 9 Britton Robinson buffer. Under these conditions, the reduction of metronidazole is controlled by both mass transport to the microdisk and adsorption with an equilibrium constant of 4 x 10(3) mol(-1) dm(3) and a saturation coverage of 0.88 x 10(-8) mol cm(-2). The adsorption and accumulation of metronidazole on the surface of the carbon fiber allows its determination at low concentrations by square wave adsorptive stripping voltammetry. A detection limit for metronidazole of 5 x 10(-7) mol dm(-3) and a R.S.D. of 3.7 % at 1 x 10(-6) mol dm(-3) (n = 4) were obtained with a two electrode system with no stirring during the accumulation step. Based on this method, a simple procedure for the determination of metronidazole in urine is described which requires no pre-treatment of the sample before analysis
First observation of Bs → J/ψf0(980) decays
No full textUsing data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the system. Using a fit to the π+π− mass spectrum with interfering resonances gives . In the interval ±90 MeV around 980 MeV, corresponding to approximately two full f0 widths we also find , where in both cases the uncertainties are statistical and systematic, respectively
Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
No full textThis Letter reports a measurement of the CP violation observables SJ/ψK0S and CJ/ψK0S in the decay channel B0→J/ψK0S performed with 1.0 fb−1 of pp collisions at s√=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψK0S=0.73±0.07(stat)±0.04(syst) and CJ/ψK0S=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within
expectations from the Standard Model
Measurement of the D+/- production asymmetry in 7 TeV pp collisions
No full textThe asymmetry in the production cross-section \sigma of D+/- mesons, A_P = (\sigma(D+) - \sigma(D-))/(\sigma(D+) + \sigma(D-)), is measured in bins of pseudorapidity \eta and transverse momentum p_T within the acceptance of the LHCb detector. The result is obtained with a sample of D+ -> K_S pi+ decays corresponding to an integrated luminosity of 1.0 fb^-1, collected in pp collisions at a centre of mass energy of 7 TeV at the Large Hadron Collider. When integrated over the kinematic range 2.0 K_S pi+ decay is negligible. No significant dependence on \eta or p_T is observed

1. In this experiment the author studied the relation between the Plant sue and occurrence of fasciated flower sta1k in connection With the seed production of Jpanese ever-season radish.
2. As the seed production of Japanese ever-season radish was
impossible in the area Where the annual mean temperature exceeds 18。C, the experiment was carried out at the Fu Show-Shan Farm ( 2,250 meter altitude, annual mean temperature 12.5。 C ), Taichung
prefecture during the period of January 1964 to June 1965. The radish seeds were sown on the first day of each month in 1964. The plants which were sown in January, February, and March bolted and flowered in the same year, others bolted and flowered in the next year.
3. It is note worthy that the occurrence of fasciated flower stalk were closely related with plant size, other words, the plants which were sown from April to September had large plant size at flowering season, and all of these plants bolted fasciated flower stalks. No seed was obtained from these plants. On the other hand the plants which were sown in January' February' March, October November, and December bolted flowered, and produced seeds normally in spite Of they were small in plant Size. The author also observed that early seeding resulted in higher production of seeds

Prompt charm production in pp collisions at √<span style="text-decoration:overline">s</span>=7 TeV
No full textCharm production at the LHC in pp collisions at s√=7 TeV is studied with the LHCb detector. The decays D0→K−π+, D+→K−π+π+, D⁎+→D0(K−π+)π+, D+s→ϕ(K−K+)π+, Λ+c→pK−π+, and their charge conjugates are analysed in a data set corresponding to an integrated luminosity of 15 nb−1. Differential cross-sections dσ/dpT are measured for prompt production of the five charmed hadron species in bins of transverse momentum and rapidity in the region 0<pT<8 GeV/c and 2.0<y<4.5. Theoretical predictions are compared to the measured differential cross-sections. The integrated cross-sections of the charm hadrons are computed in the above pT-y range, and their ratios are reported. A combination of the five integrated cross-section measurements gives
σ(cc¯)pT<8 GeV/c,2.0<y<4.5=1419±12(stat)±116(syst)±65(frag) μb,
where the uncertainties are statistical, systematic, and due to the fragmentation functions
Increasing the usability of formal specification techniques through a combination of complementary formal languages and automated verification tools
No full textThis paper addresses three main issues. Firstly, the combination of formal specification languages to model proposed systems. For this paper we introduce the dual specification of a case study system using the formal languages LOTOS and the Z notation to capture the behaviour of the complete system, including the modelling of data abstraction, information hiding and modularisation. Secondly, the production of an industrial-strength specification using a mechanical, automated CASE tool to verify the syntax of the formal specification. It is hoped that specifications which are verified mechanically will be more widely acceptable to industry because of the consistency enforced by the CASE tools used to check them. Finally, the transition from formal specification to implementation using the dual formal specification approach introduced in this paper
