Результати проведених клініко-статичних досліджень показали, що жінки, які завагітніли після консервативного і хірургічного лікування неплідності, складають групу високого ризику, щодо розвитку в першу чергу загрози переривання вагітності, особливо в ранніх термінах, фетоплацентарно недостатності, пізніх гістозів, аномалі розвитку пологово діяльності, які в свою чергу призводять до високо частоти оперативного розродження. Порівняльний аналіз показав, що характер порушень, які виникають при вагітності, обумовлений дією патогенетичних змін, які спостерігались при неплідності. У жінок після хірургічного та ендоскопічного лікування неплідності розвивається частіше загроза переривання вагітності та фетоплацентарна недостатність, гестози, ніж після консервативного лікування, що негативно впливає перинатальні наслідки розродження. Проведений аналіз свідчить про недостатню ефективність традиційних лікувальних заходів у жінок після лікування неплідності, належність їх безумовно до групи високого ризику, які потребують перегляду підходів до тактики ведення вагітності ті пологів у даній групі хворих.
Flatworms (Schmidtea nova) prey upon embryos of the common frog (Rana temporaria) and induce minor developmental acceleration

Published: June 2015

Amphibians vary in the degree of pre-metamorphic developmental plasticity in response to risk of predation. Changes in hatching time and development rate can increase egg or tadpole survival respectively by shortening the duration of the more vulnerable stages. The intensity of predator induced developmental response and its direction, i.e. delayed, accelerated, or none, varies considerably between amphibian and predator species. We surveyed freshly deposited clutches of the European common frog Rana temporaria in a population in Braunschweig, Germany and found that 62% (N = 20) of the clutches contained planarians (Schmidtea nova), with an average of 3.94 ± 0.79 and a maximum of 13 planarians per clutch. A laboratory predation experiment confirmed that this planaria preys on R. temporaria eggs and early embryos. We further exposed freshly laid egg masses to either free, caged, or no planarians treatments using floating containers within a breeding pond where the two species co-occur. After 10 days exposure, embryos showed developmental stages 14-25 along the Gosner scale with statistically significant positive effects of both predator treatments. The observed effect was rather slight as predator-exposed individuals showed an increase by a single Gosner stage relative to those raised without planarians. The detected trend suggests that direct and indirect cues from flatworms, rarely considered as anuran predators, might induce a developmental response in R. temporaria early developmental stages.
Settlement of the Claims of Individuals by Their Countries
Authors: Bettauer Ronald J. 
Published: June 2015

A nation can settle the claims of its citizens against a foreign government. The injury must have been an internationally wrongful act by another State and the injured citizen must have been a national of the espousing state. Generally, a claim may not be espoused unless the “local remedies” rule is satisfied.
The United States has a long history of settling individual claims against foreign countries by international agreements. The Supreme Court has upheld this practice.
The Peace Treaty with Japan contains a mutual waiver of claims. Yet Americans who had been forced to work as slave laborers for Japanese companies filed lawsuits. The u.s. executive branch and courts held that their claims had been settled.
Certain Holocaust claims were resolved under a new format. Thus, creative approaches to resolving claims are available outside the normal legal framework.
Perceived Effectiveness of Social Networks for Job Search
Authors: Zhitomirsky-Geffet Maayan , Bratspiess Yair 
Published: June 2015

AbstractOne of the most common uses of the capabilities of social networks is for professional, and business purposes. The literature presents conflicting evidence as to the effectiveness of different networks for professional purposes. Therefore, our primary research aim is to conduct a comparative investigation of the effectiveness and factors which influence the effectiveness of different social networks for finding a job. This study focuses on the two most popular networks, Facebook and LinkedIn; the former is not intended specifically for professional purposes while the latter is. To this end, we conducted a user study based on over 220 responses to a questionnaire especially designed for this goal. In our analysis, we distinguish and compare between the users’ perceptions and attitudes toward the effectiveness of the network and its actual helpfulness for finding a job in past experience. Our results indicate that different demographic and network usage variables influence the attitude to effectiveness and helpfulness of the networks. Thus, users with lower incomes preferred Facebook, while more educated users with higher incomes perceived LinkedIn as more effective. Interestingly, we found that despite the fact that LinkedIn was perceived as significantly more effective for finding a job by the majority of the users, the actual helpfulness of the two networks was assessed as quite similar. Our findings provide direct evidence for bridging social capital increase by online social networks. This study has practical implications and recommendations that will enable job candidates to improve their job-hunting strategies.
Theoretical And Practical Investigations Of V-Block Waviness Measurement Of Cylindrical Parts
Authors: Adamczak Stanisław , Zmarzły Paweł , Janecki Dariusz 
Published: June 2015

AbstractThe paper relates to the problem of adaptation of V-block methods to waviness measurements of cylindrical surfaces. It presents the fundamentals of V-block methods and the principle of their application. The V-block methods can be successfully used to measure the roundness and waviness deviations of large cylinders used in paper industry, shipping industry, or in metallurgy. The concept of adaptation of the V-block method to waviness measurements of cylindrical surfaces was verified using computer simulations and experimental work. The computer simulation was carried out in order to check whether the proposed mathematical model and V-block method parameters are correct. Based on the simulation results, a model of measuring device ROL-2 for V-block waviness measurements was developed. Next, experimental research was carried out consisting in evaluation of waviness deviation, initially using a standard non-reference measuring device, and then using the tested device based on the V-block method. Finally, accuracy of the V-block experimental method was calculated.
Determination of the uncertainty of the measurements performed by coordinate measuring machines
Authors: Krawczyk Marcin , Gąska Adam , Sładek Jerzy 
Published: June 2015

Abstract
Today many different systems are working in accordance with the idea
of coordinate measuring techniques. It is possible to use the same
measuring software with optical or contact coordinate systems as well
as with a 3D scanners. This gives the opportunity to use different
measuring systems for the same tasks. Consequently, it is possible to
build faster and more efficient techniques for controlling the
production. For example: a fast check of car body production with 3D
scanner systems and once per shift accurate measurement of the same
element with reference Coordinate Measuring Machines. The main purpose
of measurements in industry is the assessment of the conformity or
nonconformity of the production with the specification. The
specification can be written in classical paper documentation or saved
in CAD-file. Never-mind how specification is written or saved, the
uncertainty of the measurement should be taken into consideration,
according to the ISO 14253-1 guideline. In the case of a supplier –
to his benefit, by extending the area of conformity and in the case of
production control – by reducing the area of conformity. Evaluation
of the coordinate measurement accuracy is very complicated task,
especially elaborating of one method for all Coordinate Measuring
Systems. Until now, majority of methods focus only on the Coordinate
Measuring Machines. ISO 15530 family of standards can be noticed in
this area, however, many problems still remain unsolved.
Studies on the Diffusion of 37Ar and the Thermal Annealing of 51Cr Recoil in Neutron Irradiated CaCrO4-Crystals
Authors: Ikeda Nagao 
Published: June 2015

Summary
The apparent similarity of the rare gas diffusion and the recoil annealing processes both resulting in “pseudo-plateaux” leads to study these processes in CaCrO4-crystals in order to find out a possible relationship. The material used was crystallized from solution, dried at room temperature (sample A) and at 200° C (sample B), an average grain size of 130 μ
was selected and irradiated for 8 hours with pile neutrons in a flux of 4 x 1012n/cm2 · sec. The diffusion of the homogenously distributed 37Ar, produced by 40Ca (n, ɑ) process was investigated in the temperature range from 100 to 800° C. The thermal annealing of (n, γ) 51Cr-recoil fragments could be measured between 100 and 300° C. - It was found that the percentage of released 37Ar is much dependent on the thermal treatment of the CaCrO4-crystals. For instance about 52% of the 37Ar diffused already in 3 hours at 300° C from sample (A), while from the tempered sample (B) only about 5% was lost. In both preparations the 37Ar-release reaches 100% at about 800° C possibly favoured by oxygen liberation.
In the range of 300 ~ 700° C, linearity of log D with 1/T was observed. This part of the curve should be due to the normal volume diffusion. 37Ar-diffusion coefficients at 200° C were measured to be 6,0 · 10-11 cm2/sec for sample (A) resp. 7,7 · 10-15 cm2/sec for sample (B). At 300° C, 3,2 · 10-10 for (A) resp. 1,1 · 10-12cm2/sec for (B).
The initial retention of recoil 51Cr was found to be 10% higher in sample Β which can be explained by the fact that the instantaneous recombination reaction is hindered by adsorbed molecules and lattice imperfection. The thermal annealing at the earlier stage formally follows first order kinetics, the reaction rate constants are almost the same for both samples at a given temperature. In multi-step annealing experiments R∞ reaches characteristic plateau-values which can be obtained also by a single-step heating at the respective temperature. This is not the case in the multi-step 37Ar-diffusion experiments which are found to be very sensitive to the "history" of the sample. The differences in the Ar-diffusion and the 51Cr-annealing-multi-step curves are explained by the pronounced physical and the more chemical nature of the processes involved.
The Dead Time of a G.M. Counter Tube
Authors: Brinkman G. A. 
Published: June 2015

Summary
In this article it will be proved that the commonly used formula for dead time corrections :[xxx] (Ν' is the true and Ν the measured count rate, r the dead time) is correct for a G.M.-counter tube and also for high count-rates. However τ seem to be a function of N.
Three often used methods for measuring the dead time τ are discussed (the two samples method ; the method of a series of samples in which the relative intensities are very well known; the method of a shortlived radioisotope), and also for each of these three methods the best way to calculate the dead time from the experiments. The two samples method, combined with a very simple formula of SCHULZE, seems to be the most attractive solution.
The theory has been illustrated by a number of experiments according to the three different methods.

The considerable spread of results demonstrates the different conditions of formation of the quartz crystals.
Recuit thermique et rôle de l’eau de cristallisation dans le trioxalatoferrate de potassium irradié par neutrons
Authors: Rusi A. , Calusaru A. 
Published: June 2015

Résumé
Le processus de recuit thermique du trioxalatoferrate de potassium irradie aux neutrons correspond à une cinétique des isothermes avec pseudo-paliers différents. Les courbes de recuit, tracées respectivement pour le produit cristallisé avec de l’eau légère, avec de l’eau lourde et sans eau de cristallisation, montrent que le processus est distribue dans un spectre d’énergies d’activation. En représentant ces spectres, on a trouve pour les énergies d’activation les valeurs caractéristiques suivantes: 0,50-0,57 eV pour le réseau avec de l’eau légère, 0,63-0,67 eV pour le réseau avec de l’eau lourde et 0,52 eV pour le réseau sans de l’eau de cristallisation.
Le rapport Fe3+/Fe2+ dans le recul est notablement influence par la présence de l’eau dans le réseau cristallin. Dans les réseaux cristallises avec de l’eau, ce rapport est situe dans l’intervalle 1,18-1,35 et en absence d’eau ce même rapport a une valeur voisine de 0,6.
L’oxydation totale du Fe2+ pour des températures inférieures à celles où commence la guérison, montre que seul le Fe3+ participe au mécanisme des réactions.

Rapid Radiochemical Separation by Adsorption
Authors: Rai R.S. , Nethaway D.R. , Wahl A. C. 
Published: June 2015

Summary
Conditions are described under which rapid and essentially quantitative adsorption occurs from aqueous solutions for 140Ba++ on BaS04 (s), 90Sr++ or 85Sr++ on SrCO3 (s), and 113SnIV on SnS2 (s) or SnS (s). The VI presence of UVI in solution does not interfere with the adsorption. These processes, which may involve isotopie exchange, offer convenient and rapid methods for the separation of Cs+ from Ba++ at low concentration, Rb+ from Sr++ at low concentration, and InIII from SnIV at low concentration, and thus the processes are applicable to the separation of short-lived fission products from their immediate descendants.

Diversity and Diversification of Higher Education: Trends, Challenges and Policies
Authors: Teichler Ulrich 
Published: June 2015

Most current discussions of diversity within higher education systems focus on comparing and contrasting universities located at different positions in the vertical rankings hierarchy. This paper innovates by identifying trends and patterns in horizontal diversification—i. e., diversity of types of study programs, educational concepts, and specializations—and ultimately reaches the conclusion that the current frenzy over rankings is causing quality to be unevenly distributed throughout higher education systems and undermining the concept of “the wisdom of the many.” It begins by distinguishing between the various types of diversity. It then describes various educational reforms and attempts to engineer horizontal diversity across Europe. A discussion follows about the origins of ranking systems and how they took root and gained currency in Europe, where informal differences between universities had previously been seen as trivial and secondary to formal differences, and the possible damaging implications such rankings might have for the quality of education throughout the entire world. Higher education policymakers, the paper concludes, must deliberately focus on bolstering the quality of all educational institutions, not just those with the highest rankings.
Creating the History of University. Review of the book: Vishlenkova Y., Savelyeva I. (eds) (2013) The Social Class of Russian Professors. Architects of Statuses and Implications.
Authors: Rudneva Yana 
Published: June 2015

A lot of potential is held by classifying university research as an individual discipline. Its evolvement is now progressing through conceptualizing the subject field and testing various disciplinary approaches towards describing the university as a heterogeneous object. The reviewed multi-authored monograph serves an example of how efforts of experts in different fields can be efficiently integrated to study the range of problems associated with university existence and transformation. The monograph includes a number of original authors’ theories that may help define the unique features of the new disciplinary field. The articles contained in the monograph refer to the critical oeuvres and ideas that provided for the tools required for present-day einterpretation of the notion of university; the authors unveil the paradoxes of “the great historical narrative” that come to surface when traditions of the past are revised for the sake of the present; the monograph also investigates into the issue of discursive nature of historical sources and narratives created on their basis.
Repeated General Anesthesia in a Patient With Noonan Syndrome
Authors: Asahi Yoshinao , Fujii Ryosuke , Usui Naoko , Kagamiuchi Hajime , Omichi Shiro , Kotani Junichiro 
Published: June 2015

Abstract
Noonan syndrome (NS) is an autosomal dominant disorder characterized by facial anomalies, short stature, chest deformity, congenital heart diseases, and other comorbidities. The challenges faced during anesthetic management of patients with NS could be due to congenital heart diseases, hemostatic disorders, and airway anomalies. Here we describe dental treatment under general anesthesia performed for a 28-year-old man with NS. He had characteristic features of NS along with mild pulmonary valve stenosis. Dental treatment under general anesthesia was performed successfully on 13 occasions with nasotracheal intubation under curve-tipped suction catheter guidance or insertion of a reinforced laryngeal mask airway. This case suggests that for patients with NS, who might present several challenges, dental anesthesiologists should consider the extent of the patient's disorders to enable them to perform dental treatment safely under general anesthesia.
Les perspectives de développement durable dans le bassin du lac d'Aiguebelette (Savoie) (Sustainable development perspectives in the bassin of the lake of Aiguebelette (Savoy)
Authors: Tissut M. 
Published: June 2015

Abstract. - The lake ofAiguebelette (Savoy, France) an its watershed represent a site of high patrimonial value. To avoid its degradation requires a sustainable development strategy.
The "contrat de lac" signed by several partners has been operative since 1998 and is expected to ensure water quality preservation. Another agreement, gathering all the villages of the watershed gave rise to a structure named "Communaute de Communes du lac d'Aiguebelette" which may later be able to drive a sustainable development program for the site.
However, the present lack of efficient leading strategy either for agriculture or for tourism, the urbanisation pressure exerted by the nearby town Chambery and the presence of a highway close to the lake threaten the evolution towards sustainable development.
