Potential for a new muon g-2 experiment

A new experiment to measure the muon g-2 factor is proposed. We suppose the sensitivity of this experiment to be about 0.03 ppm. The developed experiment can be performed on an ordinary storage ring with a noncontinuous field created by usual magnets. When the total length of straight sections of the ring is appropriate, the spin rotation frequency becomes almost independent of the particle momentum. In this case, a high-precision measurement of an average magnetic field can be carried out with polarized proton beams. A muon beam energy can be arbitrary. Possibilities to avoid a betatron resonance are analyzed and corrections to the g-2 frequency are considered.Comment: 5 pages, 1 figur

Description and Quality of Some Mango Varieties Grown in Hawaii and Their Suitability for Freezing

Quick-freezing of Hawaii fruits is a comparatively new process in the Islands, and much work is needed to determine the methods that will provide products of high quality. Mangos grow on all the Hawaiian Islands, but not all varieties are available on every island. Since 1949, this laboratory has frozen all of the superior named mango varieties obtainable (unknown seedlings were not included), varying the treatment and type of product, and testing the frozen samples after different periods of storage. This paper presents the descriptions of 21 Hawaii varieties of mangos and the results of freezing tests (for 20 varieties) for two seasons

Vitamin Values of Foods in Hawaii

Many of the data on the vitamin content of foods grown, used, and/or produced in Hawaii which are given in this bulletin were first published in mimeographed form in April. 1942, by the Hawaii Agricultural Experiment Station, as Progress Notes No. 36 to make available information on local and semitropical foods that might be of use in connect ion with food planning during the war. Because of the many requests for these Notes, a revision with some additional data was published in June, 1944. This bulletin includes all data contained in Progress Notes No. 36, material that could not be included at that time, and material which has accumulated since.In addition to many familiar American foods. there are available in Hawaii many foods of tropical and semitropical origin and foods characteristic of the diets of the racial groups which make up the population of the Islands. To provide information about the vitamin content of these foods, which are not included in published tables but which are of importance in local diets, and to determine the comparative vitamin value of fruits and vegetables produced locally with those produced elsewhere, a general survey of the vitamin values of foods in Hawaii was undertaken. The results of this survey are presented in this bulletin. Following a brief discussion of the vitamins and their importance in nutrition, and a statement of the methods used, the vitamin A, vitamin B1 (thiamine), and vitamin C (ascorbic acid) contents of a large number of foods are summarized in table form, with a brief discussion of the resuits. Results are also given for some detailed ascorbic acid studies and for a few foods tested for vitamin D. Detailed supporting data are included in the appendix

Public access to private land in Scotland

This article attempts to understand the radical reform of Scottish land law in its provision for a general right of public access to private land introduced in 2003 as part of land reform legislation, an important aspect of the initial agenda of the Scottish Parliament revived in 1999. The right is to recreational access for a limited period and the right to cross land. Access can be taken only on foot or by horse or bicycle.   As a starting point clarification of the misunderstood pre-reform position is attempted. The essential point is that Scots common law does not give civil damages for a simple act of trespass (as English law does) but only a right to obtain removal of the trespasser. Under the reforms the longstanding Scottish position of landowners allowing walkers access to the hills and mountains becomes a legal right.   A critical aspect of the new right is that it is one of responsible access; provided a landowner co-operates with the spirit and system of the Act access can be denied on the basis that it is not being exercised responsibly. But the onus is on the landowner to show that the exercise of the right is not responsible.   Although the right applies to all land a general exception protects the privacy of a domestic dwelling. Early case law suggests that the scope of this limit depends upon particular circumstances although reasonable 'garden ground' is likely to be protected. There are various particular limits such as school land.   Compliance with the protection of property under the European Convention on Human Rights is discussed. The article emphasises the latitude, open to nations, for limitations to the right of ownership in land in the public interest. The extent of the Scottish access inroad illustrates this. This leads to the conclusion that 'land governance' – the subject of the Potchefstroom Conference at which the paper was initially presented – largely remains a matter for domestic law; the lex situs concept is alive and well.  &nbsp
