This paper proposes the development of intelligent sensors as an integrated systems approach, i.e. one treats the sensors as a complete system with its own sensing hardware (the traditional sensor), A/D converters, processing and storage capabilities, software drivers, self-assessment algorithms, communication protocols and evolutionary methodologies that allow them to get better with time. Under a project being undertaken at the Stennis Space Center, an integrated framework is being developed for the intelligent monitoring of smart elements. These smart elements can be sensors, actuators or other devices. The immediate application is the monitoring of the rocket test stands, but the technology should be generally applicable to the Intelligent Systems Health Monitoring (ISHM) vision. This paper outlines progress made in the development of intelligent sensors by describing the work done till date on Physical Intelligent Sensors (PIS) and Virtual Intelligent Sensors (VIS).

One of the minor misfortunes of the war has been the suspension of many lines of scientific investigation; while another has been the difficulty of receiving information concerning researches in lands in which, despite the war, it has been possible to pursue important original or collative work. The U.S.A. is a case in point, and it will be of interest to all students of ice and snow that there has appeared from the pen of Mr François E. Matthes, the well-known head of the Section of Glacial Geology of the U.S. Geological Survey, an important monograph entitled “Glaciers”. It is published as Chap. 5 in Hydrology (Physics of the Earth, Vol. 9, edited by Oscar E. Meinzer, New York: McGraw-Hill Book Co., 1942). This chapter of seventy pages reviews some of the work done and the advances made in recent years, more particularly in glaciology, as distinct from glacial geology. Incidentally, it is common knowledge that while there is in all a very large body of students of glacial geology, that is to say of the actual effects of ice masses upon the land surface, there are at work remarkably few glaciologists, whose particular study is the physical condition and constitution of those masses, even in countries where glaciers are a normal feature of the landscape.

The excavations which were made in June and July of 1902 were included in the report of the work done in 1901.The excavations, of which the results are now to be reported, did not begin until 11th August and were continued until October. The greater part of House No. 4 had, however, been excavated in 1900, but our description of it was postponed until the whole should have been brought to light.

The basic condition of forest management development is the accessibility of the forest. A design of the forest road network in relation to all-society functions of forests has been made in the catchment of the Vilčok stream. The catchment is situated in Protected Landscape Area Beskydy. The method Quantification and quantitative evaluation of functions of forests as a basis for their evaluation (Vyskot et al. 2003) was used for the design. This method can be applied to road planning. It can serve as another component in the decision-making process of the planning of forest road construction.

This article is concerned with the extent of a fiduciary's obligation to account for profits that have been made in breach of fiduciary duty. In particular, it responds to suggestions made recently by some senior judges that the courts ought to have a wide-ranging discretion to alter the degree to which a fiduciary must account for profits. It is well-settled that a fiduciary must account for profits that have been generated from his fiduciary position or in circumstances involving a conflict between the fiduciary's duty and his interest. The fiduciary need not account if the profit or conflict was properly authorised, in which case there was no breach of fiduciary duty. But in the absence of such authorisation, the fiduciary must account for all of the profit that has been made in breach of fiduciary duty, other than insofar as the court grants an equitable allowance to the fiduciary for work done in generating that profit. The question addressed here is whether the court ought to have a wider discretion to award an account of only part of the profits that a fiduciary has made in breach of fiduciary duty, leaving the remainder of the profits in the fiduciary's hands?

Do So

Between 2013 and 2015, Canada signed nine bilateral investment treaties (BITs) with countries in Africa. Canada was remarkably successful in imposing its model investment treaty on its African partners. Canada’s success might be considered surprising. Investor-state arbitration cases have shown the strong binding character of BITs and the corresponding need for host states to ensure that treaties reflect their distinctive priorities. In seeking to do so, African countries could have looked to African regional initiatives for expressions of made in African investment policies. African negotiators could have benefited from the substantial work done by UNCTAD and others to provide new forms of international investment rules that make BITS more supportive of sustainable development. Despite stronger incentives for African countries to assert themselves in BIT negotiations and resources for them to draw on, however, Canada’s recent BITs suggest that political and economic power continue to define the outcome of negotiations.

The enormous diversity of HIV-1 is a significant impediment in selecting envelopes (Envs) that can be suitable for designing vaccine immunogens. While tremendous progress has been made in developing soluble, trimeric, native-like Env proteins, those that have elicited neutralizing antibodies (Abs) in animal models are relatively few. A strategy of selecting naturally occurring Envs suitable for immunogen design by studying the correlation between efficient cleavage on the cell surface and their selective binding to broadly neutralizing Abs (bNAbs) and not to non-neutralizing Abs (non-NAbs), properties essential in immunogens, may be useful. Here we discuss some of the challenges of developing an efficacious HIV-1 vaccine and the work done in generating soluble immunogens. We also discuss the study of naturally occurring, membrane-bound, efficiently cleaved (naturally more sensitive to furin) Envs and how they may positively add to the repertoire of HIV-1 Envs that can be used for vaccine immunogen design. However, even with such Envs, the challenges of developing well-folded, native-like trimers as soluble proteins or using other immunogen strategies such as virus-like particles with desirable antigenic properties remain, and are formidable. In spite of the progress that has been made in the HIV-1 vaccine field, an immunogen that elicits neutralizing Abs with significant breadth and potency in vaccines has still not been developed. Efficiently cleaved Envs may increase the number of available Envs suitable for immunogen design and should be studied further.

In the year 1881 I briefly described (1) a method of experimenting by which the heart and lungs of a Dog or Cat could be completely isolated physiologically from the remainder of the body of the animal, and kept alive some hours for study in an apparently normal condition, the heart beating regularly and maintaining a good arterial pressure. Since then I have been at work investigating the influence of various conditions upon the pulse-rate of Dogs’ hearts so isolated; while under my supervision several of my pupils have been engaged in studying the work done in a unit of time by such hearts under different external conditions. As regards the effects of variations of arterial pressure upon the pulse-rate of the isolated Dog’s heart, my results have already been published (2); and detailed observations as to the influence of variations in venous pressure will shortly be printed. But in so far as the influence of temperature variations upon the cardiac rhythm is concerned, only a brief preliminary announcement (3) has been made. In the present paper I propose to give a full account of my experiments upon this subject, which is one that, apart from and in addition to its purely physiological interest, has considerable practical importance in connexion with inquiries as to the immediate cause of the quick pulse so constantly found in warm-blooded animals suffering from fever.
