Diurnal Period

Cosmic ray results obtained on a journey to and fro between Australia and Japan are described. The apparatus was that used previously on the H.M.A.S. Wyatt Earp(l), but since modified, and extended to record showers. A latitude effect of 20 per cent. was found for rays of vertical incidence. The difference between electron and meson components did not exceed the statistical errors of 2 per cent. For wide angle coincidence telescope measurements the latitude effect reduces to 13 per cent. Further it has been found that a latitude effect of some 10 per cent. exists for extensive showers of an average spread of 1 metre. An observed latitude effect of penetrating extensive showers falls, however, within the standard deviation of the measurements. The above results were not corrected for barometric and temperature effects nor for variations in height of the meson-producing layer. Evidence is presented of the existence of a semi-diurnal variation at the equator and at Kure of opposite phase to the barometric pressure variations and of about twice the coefficient of the normal barometric effect. The maximum of the diurnal period occurs at Kure at 2 hours local time and at the equator at 19 hours. A temporary increase of between 2 and 3 per cent. in cosmic rag intensity during the period July 29-31, 1948, is noted.

This paper describes the cosmic ray equipment used and the results obtained on the cruise of the Wyatt Earp between Melbourne, Australia, and the Antarctic Continent during the early part of 1948. Measurements of the total cosmic radiation over a narrow solid angle, the meson content over the same angle, and the total content over the full hemisphere were made. The difficulty of carrying out multiple correlations, when the independent variables are closely related, is discussed. The final correlation results show barometric coefficients of -0.144 per cent. per millibar (mb.) for the narrow angle total radiation, -0.114 for the meson content, and -0.192 for the total wide angle record. Long term temperature coefficients of -0.063 per cent. per degree C., -0.051 per cent. per degree C., and -0.012 per cent. per degree C., respectively, are obtained. The need to separate the daily and long-term temperature coefficients in regions where continental climates exist is shown. Daily temperature coefficients of 0.14 per cent. per degree C., 0.24 per cent. per degree C., and 0.16 per cent, per degree C. are obtained. It is found that no measurable latitude effect remains after pressure and temperature corrections have been made. The ratios of the total to meson content and the narrow angle intensity to wide angle intensity are independent of latitude south of Melbourne. A possible effect due to a magnetic disturbance on February 15 is noted, but later more severe storms did not produce any noticeable result. The results obtained are compared with those of other workers.

Purpose Double rotor induction machine (DRIM) is a particular type of induction machine (IM) that has been introduced to improve the parameters of the conventional IM. The purpose of this study is to propose a dynamic model of the DRIM under saturated and unsaturated conditions by using the equations obtained in this paper. Also, skin and temperature effects are considered in this model. Design/methodology/approach First, the DRIM structure and its performance will be briefly reviewed. Then, to realize the DRIM model, the mathematical equations of the electrical and mechanical part of the DRIM will be presented by state equations in the q-d axis by using the Park transformation. In this paper, the magnetizing fluxes saturation is included in the DRIM model by considering the difference between the amplitudes of the unsaturated and saturated magnetizing fluxes. The skin and temperature effects are also considered in this model by correcting the rotor and stator resistances values during operation. Findings To evaluate the effects of the saturation and skin effects on DRIM performance and validate the model, the machine is simulated with/without consideration of saturation and skin effects by the proposed model. Then, the results, including torque, speed, stator and rotor currents, active and reactive power, efficiency, power factor and torque-speed characteristic, are compared. In addition, the performance of the DRIM has been investigated at different speed conditions and load variations. The proposed model is developed in Matlab/Simulink for the sake of validation. Originality/value This paper presents an understandable model of DRIM with and without saturation, which can be used to analyze the steady-state and transient behavior of the motor in different situations.

<p>Research points to a robust negative relationship between average levels of subjective wellbeing and the distribution of subjective wellbeing. The fact that our wellbeing falls as wellbeing distributions widen suggests we care about inequalities in the lives of others. Central to this relationship is the role of place and human geography. The literature relating wellbeing to inequality in wellbeing is confined almost exclusively to inter-country comparisons. Virtually no attention has been paid to the relationship between wellbeing and inequality within countries - at the level of regions and below. The aim of this thesis is to test the generality of the inter-country evidence in the sub-national context.  I present four hypotheses which I test on three separate cross-sectional surveys: the New Zealand Quality of Life Survey, The New Zealand General Social Survey and the survey of Māori wellbeing, Te Kupenga. I follow the literature in using the standard deviation of wellbeing as a measure of wellbeing inequality. In each case the negative relationship between individual wellbeing and wellbeing inequality is clearly identifiable. The wellbeing effect of living in a place one standard deviation higher than another is roughly equivalent to the difference between the wellbeing of someone who is fully employed and someone who is unemployed and looking for work. Clearly we are highly sensitive to disparities in the subjective wellbeing of those around us.  I conduct several tests of the psychological drivers that lie behind the wellbeing response to local inequality in wellbeing. The first tests fairness perceptions, and finds sensitivity to wellbeing inequality to be higher among those who do not believe society is intrinsically fair. My test of altruism, while not as convincing empirically, suggests altruistic people may also be less affected by local wellbeing inequality. Both conclusions are consistent with the implied causation running from inequality to wellbeing.  While an important addition to the wellbeing literature, the more important implication of my findings is political. As the New Zealand Local Government Act comes up for renewal, the evidence I have assembled strongly supports providing local government with a clear purpose and the necessary funding to address the underlying causes of local inequalities in wellbeing. On empirical grounds alone, reducing wellbeing inequality is likely to make us all much happier.</p>

Background: Moderate anaemia seen in about 15-20% of pregnant women. Iron sucrose complex which is used intravenously for the correction of Iron deficiency anaemia. The drug has been able to raise the haemoglobin to satisfactory level when used in moderately anaemic iron deficient pregnant women. The objective of this study was to study the improvement of Hb% after treatment with intravenous Iron sucrose complex in moderately anaemic pregnant women belonging to 24-32 weeks of gestational age.Methods: 50 antenatal patients between gestational age 24-32 weeks with hemoglobin between 8-9.5g/dl were selected and included in this study. They were subjected to blood hemoglobin estimation, hematocrit and peripheral smear study. In each infusion, the maximum total dose administered was 200 mg iron sucrose in 100 ml of normal saline, slow IV infused over 30 minutes. Monitoring was done throughout the infusion to observe for any side effects.Results: Mean hemoglobin among the 50 patients before starting the therapy was 8.172g/dl and the mean hemoglobin at the end of one month of completing the therapy was 11.066g/dl. The rise in mean hemoglobin i.e. the difference in the mean hemoglobin before and after treatment was 2.894g/dl. The p value is 0.0001 which is statistically significant. The mean hematocrit of the 50 patients studied before starting the treatment was 26.772% with a standard deviation of 1.914. The mean hematocrit after completing the therapy was 33.872% with a standard deviation of 1.321. The difference in the mean hematocrit was 7.100% with a p value of 0.0001 which is statistically significant.Conclusions: Intravenous iron sucrose complex is well tolerated and highly efficacious in improving hemoglobin, hematocrit in the treatment of iron deficiency anaemia in antenatal women.

In Katsina metropolitan, a variety of poultry feeds are available, and the quality and standards of these feeds are critical for the production of eggs and meat. As a result, the quality of selected chicken feeds sold in Katsina metropolitan was assessed by performing proximate analysis using AOAC methodology. Super starter, grower concentrate, broiler finisher, broiler starter, broiler super starter, layer mesh, grower mesh, and layer concentrate were among the samples used. The percentage mean to standard deviation was used to express the findings. The crude protein content of the diets studied ranged from 0.46 ± 0.00 percent to, 8.24± 0.02 percent, ash content 6.31± 0.01 percent – 33.30± 0.04 percent, crude fiber content 1.03 ±0.00 percent – 3.21± 0.00 percent, lipid content 0.11± 0.00 percent, 2.30 ±0.00 percent, moisture content 4.28 ±0.25 – 6.66 ±0.78 percent, and carbohydrate content 51.78± 2.68 – 83.72 ±0.57 percent. Although there was variation in the mean and standard deviation levels among the samples analyzed, such variations were not statistically significant (P>0.05) according to a one-way analysis of variance (ANOVA) for the difference in the mean levels of parameters evaluated in eight samples
