Abstract. The AirCore is a long coiled tube that acts as a “tape recorder” of the composition of air as it is slowly filled or flushed. When launched by balloon with one end of the tube open and the other closed, the initial fill air flows out during ascent as the outside air pressure drops. During descent atmospheric air flows back in. We describe how we can associate the position of an air parcel in the tube with the altitude it came from by modeling the dynamics of the fill process. The conditions that need to be satisfied for the model to be accurate are derived. The extent of mixing of air parcels that enter at different times is calculated, so that we know how many independent samples are in the tube upon landing, and later when the AirCore is analyzed.

Poverty is one continuing social issue which is hard to solve. Dealing with this problem, Islam has already had the alternative solution that is tithe (Zakat). Zakat is implemented to decrease economy imbalanced appeared in the society. While in fact, not all the Moslem pay Zakat. There are five factors as the reason why Moslem didn’t do that. First, some Muzakki wants to deliver his zakat directly.Seconde, not all Muzakki know how much Zakat must be paid. The other factors are Limited information about Mustahik home, limited time that Muzakki have to deliver his Zakat directly and the easiness to report Mustahik data. Dealing with those factors, it is required to have an information system which can make Muzakki meets Mustahik. In this research, information system application used Extreme Programming (XP) development method. XP method is required to program a system which will be made by accomodating the users’ needs and expectations.

Field Note

The objectives of this study were to describe the classroom discourse structure, to describe how the classroom discourse is realized by teacher and students and the reasons for the realizations of the ways they are. The source of the data was English teacher and the students while the data are verbal and non verbal utterances of students and teachers. The instruments for collecting data were video tape recorder and researcher’s field note. The data were collected by observing and recording the utterances uttered by the teacher and students. The findings showed that the classroom discourse structures were dominantly realized by Initiation and Response (IR) structure. It was reflected in teacher direct, elicit and information exchanges was found that the classroom discourse structures. The other exchanges occur are boundary (framing and focusing move), directive, informing, check, accept, react, reply, nomination, marker, bid and conclusion acts. The reasons why the realization as the ways they are (1) teacher as a centre of interaction, (2) teacher gives some questions without any caring to the evaluation, appreciation and feedback without any feedback to make dialogue, (3) students have been disciplined not to speak in classes without a teacher’s direction, and most of them are unwilling to speak English.   Keywords: Classroom Discourse Structures, Initiation and Response, Sinclair and Coulthard Theory

When my paper on the Conductivity of various Substances was presented to the Society, it was intimated to me on the part of the Council of the Society, that it might be advisable to determine absolute instead of relative conductivities, the latter being alone attempted in my previous experiments. It has been partly in consequence of this intimation, as well as from the desire to make my investigations the more complete, that I have given my attention to the construction of a calorimeter which might serve for this purpose. The present communication contains a description of this instrument, with the results which it has enabled me to obtain respecting the absolute quantities of heat which emanate from the surfaces of certain substances under given conditions. 1. When a body is placed in atmospheric air (or any gas), the quantity of heat which is lost from its surface in a given time, when its temperature is higher than that of the surrounding medium, will be greater than if it were placed in a vacuum, other conditions remaining unaltered. In the latter case the heat escapes by simple radiation; in the other case a portion of the heat also escapes in consequence of the contact of the air with the surface of the heated body. Dulong and Petit ascertained by a careful series of experiments, the laws according to which the mercury contained in the bulb of a thermometer cools, or those which govern the quantity of heat which escapes from the surface of the containing bulb, when placed in a vacuum, in air, or in several kinds of gases. These experiments were made with the glass bulb naked, and also when it was silvered, so that the laws of radiation which they established were strictly in reference only to surfaces of glass and those of silver. Certain laws were identical in both these cases, and hence it was concluded, though by a limited induction, that the same laws were applicable to all other surfaces. They did not, however, give the absolute quantity of heat which, under given circumstances, and in a given time, emanates from the surfaces of the glass or silver with which they experimented. The instrument which I have constructed gives very easily this absolute amount of heat, as I believe, with very approximate accuracy.

The pandemic has led to an increase in the use of pulse oximetry to assess and manage patients with COVID-19 disease. Paul Silverston explains the principles of pulse oximetry and the factors that can affect the reliability and accuracy of readings Pulse oximetry is performed to detect and quantify the degree of hypoxia in patients with respiratory symptoms and illnesses, including patients with COVID-19 disease. Pulse oximeters are non-invasive, simple to use and inexpensive, but it is important to know how to interpret the readings in the context of the patient's symptoms and the other clinical findings. In COVID-19 disease, very small differences in the oxygen saturation reading result in significant differences in the way that the patient is managed, so it is important to be aware of the factors that can affect these readings. It is also important to appreciate that a low reading in a patient with suspected or confirmed COVID-19 disease may be the result of another disease process.

In attempting to present some observations on the kind of information on the Earth’s resources which may be obtained from spacecraft and space satellites, I think I should explain that I speak as a geographer with research interests in the field of biogeography/geobotany where I have been concerned with the use of vegetation in mineral exploration work and in the assessment of land potential for agricultural and other uses. In the course of this work I have come to appreciate major problems of regional or even continental dimensions and have become aware of the great potential offered by suitably equipped Earth resources satellites for providing information which would assist their solution. At the same time I have come to recognize the great contribution which Earth resources satellites can make in the fields of agriculture, forestry and conservation, topographical and geological mapping, hydrology, oceanography, land use and urban planning, to mention but a few. As a setting for my subsequent remarks I would like to state what I believe to be the relative positions of the U. S. A. and the U. S. S. R. on the one hand and this country and certain West European countries on the other with regard to the acquisition of information from Earth resources satellites. America and Russia have led the world in space research. They have the resources, the facilities and the technical know-how for placing spacecraft and satellites in orbit. For the effective development of Earth resources satellites, however, ground control information is essential. Here this country, together with member and former member countries of the Commonwealth possesses a body of people scattered through universities, government departments and organizations, commerce and industry whose firsthand knowledge of remote terrain in many parts of the world is unrivalled. This knowledge harnessed into an Earth resources satellites programme could enable this country to make a leading contribution to the development of the less developed parts of the world and at the same time materially assist the economy of this country.

Contemporary Standard

For the linguistic expression of the concept of knowledge, the Slavic languages use verbs deriving from the Indo-European roots *ĝnō and *ṷei̭d. They differ in terms of the availability of both types of verbs in the contemporary standard languages and in terms of their semantic range. As will be shown in this paper, these differences are interesting not only from a language-specific lexicological point of view, but also in the context of the intersection of lexicon and grammar. Covering the domain of ‘knowing how,’ the *ĝnō-based verb in Slovene (znati) has been extending into the domain of possibility and, on this basis, developing into a modal verb. While this development is not surprising from a typological point of view, it is remarkable from a Slavic perspective, since this particular grammaticalisation path towards possibility is otherwise unknown to Slavic. This peculiar feature of Slovene, which most probably relates to its long-lasting and intensive contact with German, is illustrated in the present paper by comparing Slovene to Russian on the basis of three main questions: 1) the semantic range of vedeti / vedatʹ and znati / znatʹ, 2) the lexicalisation of ‘know how,’ and 3) the relation between knowledge, ability, and possibility. The focus is on contemporary Slovene and Russian, leaving a detailed diachronic investigation and the further embedding into a larger Slavic and areal perspective for future analyses.

ABSTRACT.  A study of pyisical properties and quality of yogurt with Lactobacillus bulgaricus as a starter has been doon. Objectives of this study is to know how many percent starter of L. bulgaricus in yogurt to decrease suscepetibility to syneresis and to increase quality of yogurt. Yogurt was analyzed for susceptibility to syineresis, titratable acidity and content of crude protein and crude fat. Syinerisis of yogurt was evaluated according to centrifugal methods of Halwarkar and Kalab. The result of the study showed that yogurt with 2.5-10 % L. bulgaricus as a starter are not have any effect of susceptibility to synerisis and content of crude fat, but centripuged at 250-1000 rpm. Had significantly different (0.01) on susceptibility to synerisis. On the other hand the increasing of centrifuge rotation, increase susceptibility to synerisis. The starter of 5-10% L. bulgaricus used in yogurt able to increase titratable acidity and content of crude protein. The yogurt prepared by 10% L. bulgaricus had the highest score (3.88%) of crude protein, although there is no significant differences with yogurt using 7.5% L. bulgaricus.

Political representation and symbolic violence through discourse Seram as Nusa Ina (Mother Island) are interesting phenomenon to be studied. This research was conducted with a qualitative method by in-depth interview and participation observation which aims to know how does this discourse view. The cultural study was applied in order to comprehend the manners of creating, producing, and disseminating the meanings from the perspective of non-Seram society and what their views on the discourse in understanding Moluccas universal identity. The process of data analysis by using the cultural studies approach generated the findings i.e the Nunusaku myth that legitimizes and strengthens Seram as Nusa Ina in society, and that there was a significant influence of myth and discourse in Moluccas identity formation universally in the form of folk songs or reliefs that always shade of Seram in represents the Moluccans. The discourse of Seram as Nusa Ina for the community of non-Seram, especially for Southeast people, is not substantial because they do not have emotional connection or relationship with the genealogy and cultural discourse. They have the other myth and the other own discourse about the myth itself such as Vernusang Island which was sinking in the formation of people’s live in the Southeast. Therefore, the discourse of Seram as Nusa Ina which is forced to become a part of the discourse of Southeast People is a form of a false consciousness as well as form of political representation and symbolic violence.

The main goal of the article is to present the possibilities and methods of research on the Rurikid’s matrimonial policy in the Middle Ages on the example of a selected group of princes. As the subject of studies were chosen Mstislav Vladimirovich and his children. In total, 12 matrimonial relationships were included. The analysis of the source material revealed very unfavorable phenomena from the perspective of the topic under study. The Rus’ primary sources gave information on the conclusion of just four marriages out of twelve. The next four matrimonial arrangement inform foreign sources (Scandinavian and Norman). It should be emphasized particularly strongly that – save for two exceptions of Scandinavian provenance – the sources convey no information whatsoever as regards the political aims behind this or that marriage agreement. It appears, then, that the chroniclers of the period and cultural sphere in question did not regard details concerning marriages (such as their circumstances or the reasons behind them) as “information notable enough to be worth preserving”. Truth be told, even the very fact of the marriage did not always belong to this category. Due to the state of preservation of primary sources the basic question arises as to whether it is possible to study the Rurikids’ matrimonial policy? In spite of the mercilessly sparse source material, it is by all means possible to conduct feasible research on the Rurikids’ marriage policy. One must know how to do it right, however. Thus, such studies must on the one hand be rooted in a deep knowledge of the relevant sources (not only of Rus’ provenance) as well as the ability to subject them to astute analysis; on the other hand, they must adhere to the specially developed methodology, presented in the first part of the article.
