Ultrastructural Changes in Peach Flower Buds During Rest1

Abstract Electron micrographs of ‘Gleason Elberta’ peach flower buds, Prunus persica (L.). Stobes, during rest indicated only moderate metabolic activity prior to December 20. In the December 27 collection, however, a single membrane-bound body (microbody or lysosome) and rough endoplasmic reticulum (RER) were present. Also, the Golgi bodies (dictyosomes) were nearly mature. Heterochromatin disappeared on January 3. By the end of February the number of mitochondria, Golgi bodies, and vesicles had increased markedly. During the first week of March, large nucleopores were observed in the nucleus. These data indicated that bud cells were changing at cold temperatures during winter. Organellar changes were compared to the predicted date for end of rest (13).

INFLUENCE OF PREGNANCY SPACING ON OUTCOME OF PREGNANCY

To assess the significance of the length of time between two pregnancies on the outcome of the second we used information collected by the British Perinatal Mortality Survey of 1958. From questionnaires on the 16,994 singleton births in the first week of March 1958 and the 7,117 singleton stillbirths and neonatal deaths in March, April, and May 1958 we abstracted information on the date and outcome of any preceding pregnancy. The interpregnancy interval was taken as the length of time between this preceding pregnancy and the last menstrual period before the index pregnancy. The most important factors influencing pregnancy spacing were outcome of the preceding delivery, social class, and maternal age. When these variables had been taken into account we found that the length of interpregnancy interval had little effect on stillbirth rates. High neonatal death rates, however, occurred when interpregnancy intervals were less than six months (P <0.005), though longer intervals had no significant effects.

Female gametophyte and embryo development in western hemlock (Tsuga heterophylla)

A morphological study of the female gametophyte and embryo development was made for western hemlock (Tsuga heterophylla (Raf.) Sarg.) growing in the Victoria, B.C., area. Western hemlock follows a pattern of development similar to other members of the Pinaceae. A comparison was also made between development in western hemlock and other gymnosperm families. Meiosis of the megaspore mother cell in western hemlock begins in early February and is completed at the end of the first week in March. This is 3 weeks before pollination. Fertilization occurs 6 weeks after pollination, in the middle of May. Embryo development takes place throughout June and July and the embryo is mature by the middle of August. Seed fall occurs throughout September, 5 months after pollination.

Do careers officers give good advice?

Abstract The National Survey of Health and Development is a longitudinal study of 5,362 young people born in the first week of March 1946 and living throughout Britain. 90% of the 15-year-old school-leavers in the sample were recommended by the Youth Employment Service to take up a particular sort of work. Survey members who followed this advice stayed longer in their first job than young people who took up some other work. Evidence is presented which suggests that this better performance results not from the personality of the young people who accepted advice nor from the superior types of first job they entered, but from the accurate assessment by the careers officer of their abilities and interests.

Influence of pregnancy spacing on outcome of pregnancy.

Reported influenza in pregnancy and subsequent cancer in the child.

A longitudinal study of 1,959 infants born in the first week of March 1958 to mothers who were reported to have had influenza during pregnancy revealed an incidence of cancer of 4.1 per 1,000 compared with only 0.8 per 1,000 among the 14,791 infants of mothers who had not had influenza.This increase was caused by cases of leukaemia and other neoplasms of lymphatic and haematopoietic tissue (I.C.D. 200-209) (P <0.0001).Data from the reports of the Registrar General for England and Wales were used to estimate the number of infants born in each year from 1955 to 1964 who subsequently died of cancer before 5 years of age. The rates for each year were compared with an estimate of the prevalence of influenza during the preceding winter. After allowing for the overall trend in the cancer death rate, a highly significant correlation was shown with deaths attributed to causes classified as I.C.D. 200-209 (P <0.005), but not with deaths attributed to other cancers. The increase in the risk of developing these neoplasms among children whose mothers had influenza is estimated to be not less than fourfold. Even so the risk remains small (3 to 4 per 1,000).

Highlights of the Annual Meetings of Diabetes : UK , Liverpool Arena and Convention Centre 4 - 7th of March 2014

The annual meeting of Diabetes UK (formerly British Diabetic Association) took place in Liverpool in the first week of March. As it is the annual meeting of the association it is considered one of the largest gathering of diabetes health care professionals in United Kingdom and Europe. It attracts diabetes physicians from around the globe. The meeting had plenary sessions which focused new agents, basic science and clinical aspects of diabetes. There was strong focus on the use of technologies in the management of diabetes specially insulin pumps and closed loops systems. The named Lectures was delivered by leading names in the field. The session on new insulin was delivered by Dr Russell-Jones from Guildford, Surry. Dr Russell-Jones elaborated on long acting insulin. Of these, the recently launched insulin Degludec (by Novo-Nordisk) which has a half life (t1/2) of 25 hours (insulin glarging t1/2 is 12 hours), has a more flat pharmacokinetics it proves to be convenient for patients which could be given any time of the day with no rigid adherence to the same time of use as with glargine, more safe (compared with glargine) having less incidence of nocturnal hypos and less no excess hypos and having an HbA1c reduction similar to glargine. The second long acting insulin which is currently in phase 3 trials is U300 glargine by Sanofi. It has the same molecular weight of the conventional glargine, but it has more flat pharmacokinetic profile that lasts longer, with less overall hypos and less nocturnal hypos. It is expected to be launched early in 2015.

Height in Relation to Puberty Family Size and Social Class: A Longitudinal Study

This paper examines the relation between the height of children, the size of family from which they come, the social and educational background of their parents, and the age at onset of puberty. The 1,557 boys and 1,456 girls included in this analysis are all those from the National Survey of Child Health and Development' who were measured at seven, eleven, and fifteen years, and whose stage of sexual maturation was described by the school doctors at special medical examinations given at the last two of these ages. A full description of the National Survey is given elsewhere.2 In brief, the sample consists of all the children of nonmanual and agricultural workers born in Great Britain during the first week in March 1946, and one quarter of the children born during that week to wives of manual workers and to those of self-employed men. Illegitimate children and twins were excluded. For the purpose of this study, the boys and girls were grouped in three ways. First, by the number of brothers and sisters they had

Fluorescent Lights for Turkey Breeders

ABSTRACT WHILE many papers have been published on the use of artificial light to stimulate gonad activity among turkeys out of season, the authors have found only one experiment reported where the fluorescent tube was used as one of the sources of light. Since fluorescent tubes are used as the only source of light in many of the cage laying houses for chickens in this area, the following experiment was conducted to compare a 60-watt incandescent lamp and a 15-watt white fluorescent tube for stimulating egg production in mid-winter. Turkeys were used as the experimental birds since the sexual periodicity is fixed from year to year more in turkeys than in chickens. In this latitude (39°N.) turkeys normally do not begin laying until the first week in March unless provided with artificial light. (Scott and Payne, 1937.) These authors using information previously established by Bissonnette (1932), who worked with starlings, demonstrated . . .

ATOMIC ENERGY

THE series of talks on atomic energy which the JL British Broadcasting Corporation arranged during the first week of March in the Home Service Programme and afterwards repeated in the Third Programme have rightly been characterized by Mr. J. B. Priestley as a fine, bold enterprise in public enlightenment. No man of science or thoughtful citizen who has any conception of the implications for mankind of recent discoveries in this field can fail to welcome this effort, and the B.B.C. is to be congratulated further in publishing so promptly in the Listener (March 13) the whole series of talks, so that they can be studied at leisure by listeners and also by those who were unable or disinclined to hear the whole series. Delivered by such authorities as Prof. J. D. Cockcroft, Prof. M. L. E. Oliphant, Sir George Thomson, Prof. P. M. S. Blackett, Sir Henry Dale and Sir John Anderson, who have been in one way or another closely associated with these developments, they put before the public quietly but frankly the facts, theories and problems of atomic energy and their main implications for good or ill.

Some Effects of Fresh Water on the Fauna of a Marine Harbor

During the first week in March, 1938, Southern California was visited by an unusually severe storm. The rainfall accompanying this storm was of sufficient magnitude to cause floods over the greater part of Southern California, with an attendant loss of life and property. Although at present the Santa Ana River empties directly into the ocean, it did in times past use the entrance of Newport Bay as an outlet; and on March 3, 1938, the Santa Ana River broke through one of its levees and a portion of the discharge again found its way through the bay and out the entrance. The stream running into the bay from the break in the levee at the river was 1,000 feet or more wide, had an average depth of a little over one foot, and a velocity of about 2 feet per second, or considerably over 1 mile per hour. This break in the levee occurred at about 3 o'clock in the morning, and it ran about 4 hours before it was finally brought under control.

Some Technical Aspects of the Finance of Rearmament

THE object of this note is to discuss not the desirability of meeting part of the proposed expenditure on rearmament by borrowing, but some of the technical considerations which seem to have weighed with the Government in selecting the methods by which the additional money shall be provided. The Government has taken power to finance over a period of five years part of the expenditure of the Defence Departments up to a total of 400 millions by borrowing. The Departments are to pay 3 per cent. interest on the money loaned to them, and after their borrowing has been completed, the money will be repaid by instalments over a period of thirty years. Powers have also been taken to lend the realised surplus on the Budget, that is the Old Sinking Fund, to the Defence Departments, thus modifying the Exchequer and Audit Act of i868 which required that all surpluses realised in this way should be issued to the Commissioners of the National Debt for the purpose of debt reduction. At the time of writing (first week in March, I937), these two facts are all that is known of official intentions. In the light of recent financial history, however, it seems possible to deduce from the nature of the powers which the Government has taken, the probable character of its intentions. One of the results of the reduction in the volume of impending maturities of relatively slhort term government debt since the great conversion of I932 and of the improvement in the financial mechanism of the Unemployment Insurance Fund since the genuine balancing of the Budget in I93I, has been to increase the importance of the extrabudgetary funds which are administered by the National Debt Office on behalf of the public departments through which they arise. The existence of these funds which have

PLANETARY PHENOMENA FOR MARCH AND APRIL, 1919

The Sun passes the vernal equinox and spring begins at 8 a. m. March 21, Pacific Time. Mercury passed superior conjunction with the Sun and became an evening star on February 23, but does not attain a sufficient distance for naked eye visibility until after the first week of March. It then sets about an hour after sunset and may be seen if weather conditions are very good. The interval does not fall below an hour during the rest of the month and at the time of greatest east elongation, March 2 1 , it is about an hour and one-half. The March greatest east elongation is much smaller than the average since it occurs only a week after the planet passes perihelion. Conditions for visibility will be about as good at the next greatest east elongation occurring in July, altho the spring greatest east elongations are usually the best of the year for naked-eye observationsAfter passing elongation Mercury approaches the Sun quite rapidly, reaching conjunction and becoming a morning star on April 7. By the end of the month it has nearly reached greatest west elongation, and rises nearly an hour before sunrise. On March 11 Mercury is in conjunction with Mars, the latter planet passing about i° to the south. Venus remains an evening star, gradually drawing away from the Sun and setting later, on March 1 not quite two hours after sunset and on April 30 rather more than three hours. Altho by no means at its greatest brilliancy, which it will not reach until August, it is, after the Sun and Moon, easily the most conspicuous object in the sky. It moves during the two months not quite 6o° northward and eastward from Pisces, thru Aries, into the western part of Taurus: About the middle of April it passes between the Pleiades and Hyades groups in Taurus. Mars remains an evening star, setting thruout the two months' period at a few minutes after seven o'clock local mean time. The
