Abstract Introduction. The aim of this study was to determine the correlations between the direction and velocity of the ball in volleyball spike. We adopted the hypothesis that the direction of an attack is dependent upon the arrangement of the pectoral girdles in the phase of flight. Material and methods. The research was carried out for four different types of attacks: from the left side of the court down the line (A) and in the cross-court direction (B) and from the right side in the same directions (C and D). Sixteen young volleyball players from a Sports Championship School run by the Polish Volleyball Federation were examined. Results. The analysis of the results showed different ball velocities in different attacks. The velocity was the lowest in attack B and the highest in attack D. Conclusions. The direction of attack was produced by hitting the ball in a non-central manner and by aligning the glenohumeral joints diagonally to the net.

Variable cross-section rods are used in many parts and mechanisms. For example, conical rods are widely used in percussion mechanisms. The strength of such parts directly depends on the natural frequencies of longitudinal vibrations. The paper presents a method that allows numerically finding the natural frequencies of longitudinal vibrations of an elastic rod with a variable cross section. This method is based on representing the cross-sectional area as an exponential function of a polynomial of degree n. Based on this idea, it was possible to formulate the Sturm-Liouville problem with boundary conditions of the third kind. The linearly independent functions of the general solution have the form of a power series in the variables x and λ, as a result of which the order of the characteristic equation depends on the choice of the number of terms in the series. The presented approach differs from the works of other authors both in the formulation and in the solution method. In the work, a rod with a rigidly fixed left end is considered, fixing on the right end can be either free, or elastic or rigid. The first three natural frequencies for various cross-sectional profiles are given. From the analysis of the numerical results it follows that in a rigidly fixed rod with thinning in the middle part, the first natural frequency is noticeably higher than that of a conical rod. It is shown that with an increase in the rigidity of fixation at the right end, the natural frequencies increase for all cross section profiles. The results of the study can be used to solve inverse problems of restoring the cross-sectional profile from a finite set of natural frequencies.

This paper aims to elucidate the sliding scale between usufruct and ownership by applying a property rights framework to three Swedish forms of tenure in multifamily housing. The framework deconstructs the bundles of rights of rental, tenant-ownership and ownership to highlight commonalities and differences connected to the right to use and exclude, the right to transfer and the right to the value. It is concluded that the three tenure forms have many traits in common but that there are distinct differences in some areas, most notably in connection to the right to the value. The property rights framework applied in the study may be applicable also on a general level as a method to analyze and compare tenures of different types in different countries. Further, ways to improve the framework and cover more facets of outcomes of property rights patterns are suggested.

Abstract:According to Spinoza, there is no categorical distinction between human and non-human animals: they all belong to the same nature and all consist of bodies with corresponding ideas. This thesis gives rise to two problems. How is it possible to distinguish different types of animals, in particular nonrational and rational ones, if all of them have the same metaphysical structure? And why does Spinoza nevertheless claim that human beings have a privileged status that gives them the right to use non-rational animals? This paper examines these two problems, arguing that the solution to both of them lies in Spinoza’s all-embracing naturalism.

‘Looking to Jesus the pioneer and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of God. Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted.’ (Heb. 12.2–3.)

In a recent number of The Harvard Theological Review, Professor Douglas Clyde Macintosh of the Yale Divinity School outlines in a very interesting manner the religious system to which he gives his adherence. For “substance of doctrine” (to use a form of speech formerly quite familiar at New Haven) this religious system does not differ markedly from what is usually taught in the circles of the so-called “Liberal Theology.” Professor Macintosh has, however, his own way of construing and phrasing the common “Liberal” teaching; and his own way of construing and phrasing it presents a number of features which invite comment. It is tempting to turn aside to enumerate some of these, and perhaps to offer some remarks upon them. As we must make a selection, however, it seems best to confine ourselves to what appears on the face of it to be the most remarkable thing in Professor Macintosh's representations. This is his disposition to retain for his religious system the historical name of Christianity, although it utterly repudiates the cross of Christ, and in fact feels itself (in case of need) quite able to get along without even the person of Christ. A “new Christianity,” he is willing, to be sure, to allow that it is—a “new Christianity for which the world is waiting”; and as such he is perhaps something more than willing to separate it from what he varyingly speaks of as “the older Christianity,” “actual Christianity,” “historic Christianity,” “actual, historical Christianity.” He strenuously claims for it, nevertheless, the right to call itself by the name of “Christianity.”

We find amongst the coins minted at Durham, during the reigns of the three first Edwards, several pennies bearing particular marks in some one or other part of the coin: one has a cross moline at the beginning of the legend on each side of the piece; a second has the same cross in the second quarter of the reverse; a third has it at the beginning of the legend on the obverse only; another has a lion rampant betwixt two fleurs de lis in the same place. Some of these being placed where in succeeding reigns the mint mark stood, have been taken notice of by two writers on these subjects, but no reasons assigned for their use. There are also from the same mint two others, which have the upright limb of the cross turned in the form of a pastoral staff, one of them to the right, the other to the left; they are said to have come from the bishops mint, but the prelates name are not mentioned.

The Cape Argus Pick n Pay Cycle Tour is a major event on the road cycling calendar. The majority of cyclists travel significant distances and participation produces a substantial carbon footprint. This paper examines participants’ willingness to pay to offset their carbon footprint. The purpose of this paper is to make a contribution to the literature by linking willingness to pay to attitudes towards or beliefs (green views) about the initiatives in place, to ensure a greener cycle tour. Factor analysis is used to identify different types of cyclists, based on their green views: those with green money, those who prefer green products and the “re-cyclers”. The results of the regression analysis reveal that socio-demographic variables and the right attitude towards the environment are significant predictors of stated willingness to pay for climate change mitigation.

As the number of web services is increasing on the web, selecting the proper web service is becoming a more and more difficult task. How to make the selection results from a list of services more customized towards users’ personal preferences and help users identify the right services for their personal needs becomes especially important under this context. In this thesis, we propose a novel User Modeling approach to generate user profiles on their non-functional preferences on web services, and then apply the generated profiles to the ranking process in order to make personalized selection results. The User Modeling system is based on both implicit and explicit information from the user. Also, this is a flexible model to include different types of non-functional properties. We performed experiments using a real web service dataset with values on various non-functional properties to show the accuracy of our system.

In the article results of examinations got in case of surgical accesses through the flank and ventral wall of the stomach’s implementation on purpose to the cats’ ovariohysterectomy are given. The research work was carried out on healthy sexually-mature cats. Surgeries were done in the upper third of the right flank abdominal wall and in the behind the umbilical zone. The cross-cut on the boundary of groin and illium area in the direction from the hook-bone’s front border to the fourth nipple of the mammary gland of the appropriate side was applied on the side abdominal wall. It is established that in case of the accomplishment of cat’s ovariohysterectomy with the use of suggested surgical access through the side abdominal wall a duration of an operation and a period of healing are in line with those which are in case of application of median laparotomy. It is proved that the surgical access with the cross-cut done in the upper third of the right flank abdominal wall and on the boundary of groin and illium area in case of cat’s ovariohysterectomy secure better opportunities for the fulfillment of the surgical method than the median one. It is also noted that in case of cat’s ovariohysterectomy the surgical access through the upper third of the right flank abdominal wall with the cut in the direction from the hook-bone’s front border to the fourth nipple of the mammary gland of the appropriate side could be recommended as an alternative of an access through the middle line of the stomach.
