scholarly journals On certain correction terms required in the equations for the kinetics of simple hœmolysis

The most satisfactory method hitherto available for the measurement of percentage hœmolysis has been the potassium cell method described in an earlier paper (Ponder and Yeager, 1930). This method, however, has certain limitations and disadvantages, two of which are particularly conspicuous. (i) The galvanometer which records the photoelectric current takes several seconds to deflect, and several seconds more to settle at zero. This determines that no more than four readings of the degree of hœmolysis can be made in a minute, and that only a few points can be obtained on the percentage hœmolysis curve for rapidly hœmolysing systems. Even these points, moreover, are apt to be inaccurate, for lysis is going on during the time taken for the galvanometer to move ; the degree of lysis recorded is thus always greater than that really present at the moment the photoelectric cell first receives the light. The effect is to move the percentage hœmolysis curve over to the right by a distance corresponding to about 0-05 minutes ; this shift is of little consequence if lysis is slow, but may introduce considerable error if it is rapid. (ii) The method is unreliable in the sense that its efficiency depends on factors which are controlled with difficulty and which are liable to vary. Photoelectric fatigue, although usually absent, may appear during any experiment, the voltage of the high tension battery or of the accumulator which supplies the lamp may vary, or the potassium cell may glow as a result of a careless exposure to the light in the interval before the cells are added to the lysin in the chamber. Experience shows that these accidents often happen, and the necessity of being continually on one’s guard against them makes the measurement of percentage hœmolysis much more difficult than would appear at first sight.

In the course of examining Roman imperial medallions and coins in connexion with a study of Roman cult images, representations of Herakles Crowning Himself, a figure which appears on the reverses of medallions of Marcus Aurelius, Lucius Verus (Plate I, 2), and Commodus (Plate I, 3), merit further comment. These reverses, whether with or without legend, exhibit identical compositions. In the centre a young, beardless Herakles stands facing, his right hand raised in the act of placing a crown on his head; his left hand, close to his left hip, holds the club upwards in the crook of the elbow. Between club and elbow, the lion's skin hangs down over the forearm to a point midway along the left leg. The head, both forepaws, and tail are clearly visible dangling below. On all the medallions the die designer has made very clear the, important point that Herakles rests his weight on the left foot, with left hip thrown out and the right foot slightly back and out, giving a pronounced bow curve to the right side of the body from foot to shoulder. To Herakles' right and slightly behind him appears an apple tree on one branch of which hang the hero's quiver and bow; to his left rear is seen a square altar, festooned with garlands and with an offering burning on the top, and in her comprehensive monograph on Roman medallions J. M. C. Toynbee suggests that ‘the picture as a whole had been inspired by some bas-relief or painting now lost to us’. The question of relating the central figure to the whole composition will be taken up in Part II, in reappraising the general problem of famous statue types in medallion compositions. For the moment we may see what further progress may be made in identifying the statue type of the young Herakles Crowning Himself.

In a situation where the taxpayer [resp. person taxable] holds an invoice prior to submittal of the return/statement for the settlement period in which the tax obligation occurred on the part of the contracting party, the term laid down in Article 178 (a) of Directive 112 has been met. Whilst the holding of an invoice is the only formal requirement, the notion of ‘holding’ ought to be interpreted in a manner compliant with its colloquial understanding. In turn, ‘holding’ is not equal in meaning to ‘receiving’/‘receipt’. In the event that an economic event has occurred and the taxpayer is capable of giving evidence for it, as he holds the invoice at the moment the tax settlement is made in the return/ statement, there are no grounds that would be legitimate under the EU laws for arguing that the taxpayer must shift his vested right to have the input tax deducted to the subsequent month, being the months in which he receives the invoice. The rule of prompt implementation of the right to deduct input tax should be taken into account. If the national regulations provide for shifting the above-specified moment through formulating any additional conditions are contrary to Directive 112. It is therefore apparent that Article 86, clause 10 (b), item 1 of the Polish Value-Added-Tax Act of 11th March 2004 is not in agreement with Article 178 (s) of Directive 112 as the former sets forth a condition that is not provided in the said EU regulation–namely, the right to have the output tax reduced by the input tax only as part of the settlement for the month in which the taxpayer receives the invoice.

The 21st century is burdened by a series of dramatic changes and efforts are carried out to find potential solutions to consumerism, access to information, transient climate disequilibria, health care and demographic transformations. A new page in human history will bear witness to the introduction of new ways of thinking, new changes, new relationships and interconnections that transcend states and societies. The moment is ripe for individuals aware of the implications carried by global changes and challenges, to step up and encourage responsibility and sustainable development. Mankind is currently living in a data-rich world, where information is widely dispersed. Nevertheless, extracting the right assumptions and conclusions from the available data proves difficult as numerous social phenomena do not run with clockwork precision as the laws governing the Newtonian universe.Human awareness and intelligence demand a more responsible approach to all operations and steps should be made in determining the consequences and their impact. The goal of this paper is not restricted to providing a review but also to enforce certain ideas in relation to the complex interactions specific to society and economic activities.

Abstract The present study offers the doctrine of the right of intellectual creation new perspectives on the study of the institution of termination of the assignment contract for the patrimonial rights resulting from the intellectual creation. We believe that the present study is rich in doctrinal contributions, formulating new theses and opening the prospect for new perspectives of scientific research. Last but not least, we appreciate that the proposals made in the present study contribute not only to the activity of opinionated in the field, but also to the work of practitioners and direct beneficiaries of the legal provisions on the assignment of patrimonial rights of authors.

Abstract As they say, money can’t buy happiness. However, the lack of it can make people’s lives much harder. From the moment we open our first bank account, we have to make lots of financial decisions in our life. Should I save some money or should I spend it? Is it a good idea to ask for a loan? How to invest my money? When we make such decisions, unfortunately we sometimes make mistakes, too. In this study, we selected seven common decision making biases - anchoring and adjustment, overconfidence, high optimism, the law of small numbers, framing effect, disposition effect and gambler’s fallacy – and tested them on the Hungarian population via an online survey. In the focus of our study was the question whether the presence of economic knowledge helps people make better decisions? The decision making biases found in literature mostly appeared in the sample as well. It proves that people do apply them when making decisions and in certain cases this could result in serious and costly errors. That’s why it would be absolutely important for people to learn about them, thus increasing their awareness and attention when making decisions. Furthermore, in our research we did find some connection between decisions and the knowledge of economics, people with some knowledge of economics opted for the better solution in bigger proportion

Justice that has not existed and is apparent among the disabilities in Indonesia is very large and spread in the archipelago is very large, making the issue of equality is a very important thing especially with the publication of the Disability Act No. 8 of 2016 at the beginning of that year. Only a few provinces that understand properly and well on open and potential issues and issues will affect other areas including the increasingly growing number of elderly people in Indonesia due to the increasing welfare of the people. The government of DKI Jakarta, including the most concerned with disability, from the beginning has set a bold step to defend things related to disability, including local governments in Solo, Bali, Makassar and several other areas. Leprosy belonging to the disability community has a very tough marginalization, the disability that arises from leprosy quite a lot, reaches ten percent more and covers the poor areas of Indonesia, such as Nusa Tenggara Timur, Papua, South Sulawesi Provinces and even East Java and West Java and Central Java Provinces. If we compare again with the ASEAN countries we also do not miss the moment in ratifying the CRPD (Convention of Rights for People with Disability) into the Law of Disability No. 8 of 2016 which, although already published but still get rejections in some sections because do not provide proper empowerment and rights equality. The struggle is long and must be continued to build equal rights in all areas, not only health and welfare but also in the right of the right to receive continuous inclusive education.

The sensor behavior of nanostructured doped silica films produced by sol-gel way were examined. Hygroscopic substances and polyoxometalates were used as additives to make more significant sensitive characteristics of initial matrix. Factors that have effect on sol preparation and films forming were investigated. Adsorption activity of the sensitive films was studied and it was shown that the films had a highly developed surface with nano-size pores. Change of initial conditions of sol-gel process gives opportunity to influence on kinetics of gel formation and consequently, on structure and properties of final materials. The study showed that the conditions of the environment affected the sensors characteristics markedly, which can be improved by choosing of the right procedure of forming and treatment. Influence of type and additive substances quantity into doped films was discussed in the paper

AbstractIn the 20 years that have passed since the Karen Quinlan case exposed a simmering clinical issue to the light of day — more precisely, to the press and to judicial process — a consensus has developed in American law about how end-of-life decisionmaking should occur. To be sure, there are dissenting voices from this consensus, but they are often (though not always) about minor issues. By illustrating how this consensus has evolved, this paper explores how law is made in the American legal system and the roles that different legal and extra-legal institutions play in lawmaking.

The summary judgment procedure in South African law provides for a speedy judgment in favour of a deserving plaintiff where it can be shown that the defendant does not have a triable defence. In 2019 the Rules Board made certain drastic amendments to the procedure of summary judgment in the high court. In this article the historical development of the procedure of summary judgment will be discussed, and the new amendments to rule 32 of the Uniform Rules of Court critically evaluated. It will be argued that the amendments to rule 32 were unnecessary and that it may diminish the right to access to justice in civil disputes. It will, however, also be argued that there are some merits in the critique raised by the Rules Board in relation to rule 32 and that the Rules Board missed a golden opportunity to overhaul the entire summary judgment procedure in a more sensible manner and in line with the core constitutional values of s 34 of the Constitution. It will be argued that rule 32 should be replaced in its entirety by a new, more streamlined procedure, and some recommendations for legal reform will be made in this regard.

The commented ruling of the Constitutional Tribunal concerns the constitutionality of the provision of Article 70(1) of the Family and Guardianship Code, which provided that the time limit for a child to bring an action to deny the paternity of his or her mother’s husband is three years and runs from the moment the child reaches the age of majority, regardless of the child’s know-ledge of his or her biological origin, i.e. regardless of whether the child within that time limit acquired knowledge that he or she did not come from his or her mother’s husband and whether the child could decide to bring an action. The expiry of the three-year period resulted in the expiry of the child’s right to claim the denial of paternity of the mother’s husband and, consequently, precluded the possibility of a positive determination of the paternity of a man other than the mother’s husband. The Constitutional Tribunal found this provision to be inconsistent with Article 30 in conjunction with Article 47 in conjunction with Article 31(3) of the Constitution of the Republic of Poland. The author agrees with the position expressed by the Constitutional Tribunal in the judgment in question, which in this case provides a basis for consideration of the relationship between the right to know one’s biological origin and the value of stabilising the civil status of a child and persons remaining in an established family relationship with him or her.
