This paper is a tentative application to a particular animal, the sheep, of concepts concerning heat regulation in "warm-blooded" animals, built up over ten years of laboratory, field, and library inquiry. The heat exchange between the animal and its environment is first analysed in a quantitative, physical fashion, and the deficiencies in present knowledge are pointed out. The ways in which the animal body attempts to maintain a heat balance are next considered, and the secondary consequences of these processes to the animal economy indicated. The paper concludes with a brief consideration of the comparative aspects. It is essentially a formulation of the way in which the thermal physiology of any animal should be considered, using the sheep as a convenient example. Many of the data are drawn from work carried out under the author's direction.

The article presents the solution of heat balance equation system, describing heat exchange processes in ventilated envelopes, which was applied to derive formulas for the calculation of temperatures in the ventilated layers of the envelopes. The accurateness of the formulas was assessed by experimental research and analysis of the calculation results. During the process of heat exchange balance equation solution, the equations were simplified by introducing the following restriction into the derived formulas: they may only be applied for the ventilated envelopes with steel or similar coatings as their external layers, i.e. coatings having small heat capacity and minor difference between the external and internal surface temperatures. The derived formulas enable the calculation of the temperatures of the ventilated envelopes in the distance which does not exceed a half of the ventilated air gap length measuring from the air entrance into the gap. However, this restriction does not impede the estimation of the average thermal indicators of the ventilated envelopes.

The Way

Acute infections of the nervous system are among the hugest issues in the medicine considering the way that early affirmation, gainful dynamic and speedy association of the treatment can be lifesaving. Standard routine assessment of CSF in meningitis doesn't commonly give speedy definitive information without a doubt. Therefore there was need for additional tests. The present study conducted in Department of Medicine. The study included clinical appraisal and CSF assessment of 65 occurrences of meningitis. Lumbar cut was done in each consistent case and CSF was assembled in sterile containers.In majority cases of meningitis sugar less than two third of blood sugars, and majority of TBM cases had sugar level between 40-60 mg%. Higher cell count was seen in pyogenic meningitis cases. In context to LDH levels among the different types of meningitis, significant increased CSF LDH levels was observed in TBM and PM as compared to VM and CM but no noteworthy distinction between TBM and PM. Overall conclusion of study was that estimation of CSF LDH levels is not only supplementary aid but diagnostic and differentiating aid for meningitis.

The theme of this article is the reconstruction of the doctrine of God offered by the German theologian and historian of doctrine Isaak August Dorner (1809–84), in his treatise ‘On the Proper Conception of the Doctrine of God's Immutability, with Special Reference to the Reciprocal Relation between God's Suprahistorical and Historical Life.’ Although the theme of God's immutability has received wide attention in the last years, Dorner's essay has gone largely unnoticed, and its contribution to the current debate still awaits appreciation. The following argument shall provide some building-blocks for this goal. It presupposes that Dorner's theology was shaped in dialogue with the thought of Schelling, Hegel, and Schleiermacher, but it will extend this perspective and ask for the particular systematic-theological link between Schleiermacher and Karl Barth that Dorner's essay represents.

Wearable Technologies represent an emerging theme. Probably the next emerging market where companies will focus. These devices are replacing entire categories of electronic objects in everyday life and affect the way we live, work and socialize. Among the many applications available, the author limits attention to the field of the smart video cameras. This chapter examines some of the most interesting applications of wearable cameras, with special reference to the Italian situation. In particular, the text traces a summary of the main applications in sports, spying, police, army, education, health, disabilities, and lifelogging. A part is devoted to “wearable extensions” and the concept of augmented reality.

Inferentialism is explained as an attempt to provide an account of meaning that is more sensitive (than the tradition of truth-conditional theorizing deriving from Tarski and Davidson) to what is learned when one masters meanings. The logically reformist inferentialism of Dummett and Prawitz is contrasted with the more recent quietist inferentialism of Brandom. Various other issues are highlighted for inferentialism in general, by reference to which different kinds of inferentialism can be characterized. Inferentialism for the logical operators is explained, with special reference to the Principle of Harmony. The statement of that principle in the author’s book Natural Logic is fine-tuned here in the way obviously required in order to bar an interesting would-be counterexample furnished by Crispin Wright, and to stave off any more of the same.

1. A study of the histology of the eyes of some cartilaginous fishes has been made with special reference to their reflecting tapeta.2. The rate and way in which the pigment in the melanophores spreads over the reflecting cells of the tapetum ofSqualus acanthiaswhen it is lightadapted are described.3. The reflecting plates in the tapeta are about parallel to the plane of the retina in the centre of the eye, but as we move towards the periphery they become more oblique, until near the ora they are almost perpendicular to the plane of the retina. It is shown that when we take account of the way in which the pupil limits the light which can reach the retina in all these situations the plates are arranged to be roughly perpendicular to the incident light. They reflect light either back through the pupil or on to the very black inside surface of the iris and do not scatter it to other parts of the eye.4. The reflectivity of tapeta for various angles and various wave-lengths of light has been found by several different methods, and a new and simple way of measuring the reflectivity of natural tissues is described. For the blue and green lights which will be those reaching the eye in life the reflectivity is very high, over 80%, and so approaches that of a good metallic mirror.5. The external segments of the retinal rods of cartilaginous fishes which have well-developed tapeta are only about half as long as those of other fish living in the same environment, and the retinal optical densities of photosensitive pigments in these fish are only about a half of those of fish without reflecting tapeta.

The rapid spreading of poisonous smoke is the main reason which causes death in ship fires. Ships always have long tunnels to traveling passengers or cargos. Because of their longness and straightness, smoke diffuses rapidly. Fire doors are used to stop the smoke from spreading into other parts in vessels. When the fire doors are closed, the way for evacuation is also closed. So it’s important for the professionals to develop a kind of smoke-preventing device which can let people pass by when stopping the smoke. The air curtain is a kind of smoke isolating device which is used to decrease the heat exchange in supermarket or freezer. This paper analyzes flow field, the heat control and the smoke isolating ability of air curtain used in the ships’ long tunnels with different jet angles and initial velocities. At last, a suitable angle is proposed.

The object of the present communication is to briefly consider the general and minute structure of the corallum of the recent Tubipora musica, with special reference to the association of the genus Tubipora with the extinct genus Syringopora, as advocated by many modern naturalists. The method of inquiry that I have pursued in carrying out this investigation has been principally that of preparing similar thin and transparent sections of both the recent and the extinct types; and though there are special difficulties in the way of any examination of Tubipora by this method, I have been able to overcome these in a satisfactory manner, and to prepare a number of thin sections which answer all the requirements of the case.
