Abstract

IT was generally believed during early servicing experience of gas turbines that nearly every defect could result in power losses, but the last eight years have provided operational experience which has helped in the design, and improvements have made the gas turbine a trouble‐free and comparatively reliable unit. There are still defects which may arise, but it can safely be stated that they have no bearing on the power output. The customary teething troubles of early days have been overcome and power units are now available having an overhaul life of 500 hours. This figure is being increased rapidly and in the near future, the engine life between overhauls may exceed 1,000 hours. The overhaul of an engine provides an engine with a complete life cycle and the engine goes out into service embodied with improved design details, thus making it more reliable than before. The overhaul procedure consists of stripping, washing, crack testing, inspection, building and testing the engine, and a brief comment on each has been made in these notes, supported by a typical overhaul shop layout. The gas turbine power plant operating costs consist of primary and overhead charges, but in our discussion the overhead charges pertaining to overhaul will not be considered. These notes are a generalization of a variety of gas turbines and do not relate to any particular design.

Abstract

The Milk and Dairies (Scotland) Order, 1925.—This Order, framed under Section 12 of the Act, and applying to Scotland as a whole, was issued along with the model dairy byelaws. It prescribed the form of register of dairies and dairymen, and contained provisions for the ascertainment of infectious disease at dairies, for the prevention of contamination of milk at railway stations, on the street, by means of unsuitable conveyances or unsuitable surroundings, or through insulticient protection from dust or exposure. The colouring or thickening of cream was prohibited by the Order; me use of wooden vessels, except for buttermilk, was prohibited; milk vessels for transit were required to nave marked on them the name and address of the owner, to have a proper lid, and to be locked or sealed. The Order also filled a gap in the administrative provisions of the Act by requiring every person about a dairy, if he became aware that any person in his household was suffering from an infectious disease, to notify the dairyman immediately. The dairyman must then notify the medical officer of health.

Abstract

This paper reviews academic literature related to the consequences that outside directors and boards may face in the wake of earnings restatements and suggests directions for future research. We examine loss of board seats; recruitment of new directors; proxy recommendations and shareholder support; pre-emptive director departures; director wealth effects; director reputation, litigation, and sanction risks; international evidence; and legal proposals for reform. The overall picture that emerges from the literature is that directors’ primary risk in the wake of earnings restatements is loss of board seats, in part through adverse proxy advisor recommendations and reduced shareholder support. Directors typically face little risk of legal liability or SEC sanctions, and some directors pre-emptively leave a problem company’s board and reduce their loss of interlocked board seats. Some legal scholars have called for director liability to be increased so as to promote more vigilant board oversight. Companies often focus on increasing the independence of the board in the wake of a restatement in an effort to repair organizational reputation. While researchers have revealed a host of important findings to date, much more can be learned about the effects of restatements on outside directors and boards.

Abstract

Purpose

This paper aims to study Irreversible conversion processes, which examine the spread of a one way change of state (from state 0 to state 1) through a specified society (the spread of disease through populations, the spread of opinion through social networks, etc.) where the conversion rule is determined at the beginning of the study. These processes can be modeled into graph theoretical models where the vertex set V(G) represents the set of individuals on which the conversion is spreading.

Design/methodology/approach

The irreversible k-threshold conversion process on a graph G=(V,E) is an iterative process which starts by choosing a set S_0?V, and for each step t (t = 1, 2,…,), S_t is obtained from S_(t−1) by adjoining all vertices that have at least k neighbors in S_(t−1). S_0 is called the seed set of the k-threshold conversion process and is called an irreversible k-threshold conversion set (IkCS) of G if S_t = V(G) for some t = 0. The minimum cardinality of all the IkCSs of G is referred to as the irreversible k-threshold conversion number of G and is denoted by C_k (G).

Findings

In this paper the authors determine C_k (G) for generalized Jahangir graph J_(s,m) for 1 < k = m and s, m are arbitraries. The authors also determine C_k (G) for strong grids P_2? P_n when k = 4, 5. Finally, the authors determine C_2 (G) for P_n? P_n when n is arbitrary.

Originality/value

This work is 100% original and has important use in real life problems like Anti-Bioterrorism.

Abstract

The manifesto of the Jam Section of the Food Manufacturers' Federation which was issued to the trade and to the public in October is a document which has been subjected to much unfavourable criticism by various persons for various reasons. In our opinion it fully deserves the censure it has received. It need hardly be pointed out that jam of some kind is eaten by everybody. The annual production in this country is enormous. As a combined food and stimulant for young children jam is probably unrivalled; indeed, we cannot imagine a substitute for it. “Jam is a ready means of providing carbohydrates, and children require much carbohydrate in proportion to their size.” All this, however, assumes that jam is really what it claims to be, namely, a preparation of the fresh fruit that gives the name to the jam and sugar only. This, we take it, is the view of the ordinary man. If we turn to dictionaries we find this definition or something very like it in all the dictionaries that have been published during the last one hundred and seventy‐five years. The dictionaries of the 17th century seem not to define the word; its meaning, however, was well understood. Johnson, 1755, defines the word jam as “a conserve of fruit boiled with sugar and water”—by sugar of course meaning cane sugar. All the modern standard dictionaries speak to the same effect. Murray's Dictionary has “A conserve of fruit prepared by boiling it with sugar to a pulp.” The Encyclopædic Dictionary and Wright's Universal Pronouncing Dictionary have the same. The Century Dictionary says jam is “A conserve of fruit prepared by boiling them to a pulp in water with sugar.” Webster that it is “A thick preserve made of fruit boiled with sugar and water.” Funk and Wagnall's New Standard Dictionary, “A conserve of fruit prepared by thorough cooking and stewing with sugar, reducing it to a pulp.” It is unnecessary to give further quotations; they are all to the same effect and show what the purchaser has in his mind when he asks for a pot of jam at a shop.

Abstract

An important step towards ousting the Germans from a lucrative branch of West African trade in which Germany has hitherto held almost a monopoly has been proposed by a Colonial Office Committee and adopted by the Government. This Committee was appointed a year ago by Mr. BONAR LAW, with Mr. STEEL‐MAIT‐LAND, M.P., as chairman, “to consider and report upon the present condition and the prospects of the West African trade in palm kernels and other edible and oil‐producing nuts and seeds, and to make recommendations for the promotion in the United Kingdom of the industries dependent thereon.”

Abstract

The curative effects of lemon and orange juice in treatment of scurvy have been known for about two hundred years, and long precede our knowledge of the accessory food factors in any chemical sense. It is now generally known that scurvy is caused by the absence of water‐soluble vitamin C from the diet. The anti‐scorbutic factor occurs in fresh fruits, especially orange, lemon, and tomato. Lime juice is inferior in this respect. It is also present in green vegetables and some tubers. Being readily destroyed by oxidation, it is not usually present in dried fruits or preserved lemon or lime juice. After sprouting, seeds and roots become a comparatively rich source. Thus, in contradistinction to vitamin B, which is found chiefly in dried seeds, vitamin C is associated with fresh fruit and vegetables in which active metabolic processes are proceeding. Light does not appear to be necessary for its generation in seeds on germination. The requirements by animals of this vitamin vary considerably. Thus rats, mice and rabbits can be fed without apparent harm on a diet which contains no vitamin C, but man and the ape, monkey and guinea pig are susceptible to scurvy on such a diet.

Abstract

In the June issue of THE BRITISH FOOD JOURNAL reference was made to a recently issued Report by the Ministry of Health upon the subject of bovine tuberculosis. In that Report the pasteurisation of cow's milk is referred to as a means of reducing the resulting human infection, and it is stated that “milk so treated appears to retain its valuable food properties practically unimpaired.”
