Black holes with magnetic charge and quantized mass

We examine the issue of magnetic charge quantization in the presence of black holes. It is pointed out that quantization of magnetic charge can lead to the mass quantization for magnetically charged black holes. We also discuss some implications for the experimental searches of magnetically charged black holes.Comment: RevTeX, 11 pages, Invited paper for the first editorial volume of the book series "Contemporary Fundamental Physics" by the Nova Science Publisher

Effects of Macronutrients on Seed Quality and Profitability Analysis of Sunflower Production in Northwest Pakistan

Potassium (K) and phosphorus (P) application to sunflower (Helianthus annus L.) reduced cost of production, increased seed oil and protein concentration, yield and net returns on the K and P deficient soils in Northwest Pakistan. Field experiment was conducted at the New Developmental Research Farm of NWFP (North West Frontier Province) Agricultural University Peshawar, Pakistan during summer 2006. The experiment was carried out in a randomized complete block design with split plot arrangements using three replications. Six levels of K (0, 25, 50, 75, 100 and 125 kg ha-1) were kept in main plots while four levels of P (0, 45, 90 and 135 kg ha-1) were kept in sub-plots. Increase in K and P levels enhanced seed oil concentration, on the other hand, increase in P level increased seed protein concentration but increase in K level decreased seed protein concentration. Both oil and protein yields per unit area increased significantly with increase in K and P levels. The increase in oil and protein yields of sunflower was mainly attributed to the improvement in yield components and significant increase in seed yield. The highest net returns of Rs. 25268 (grain yield basis) and Rs. 31274 (oil yield basis) was obtained from those plots that received a combination of 100 kg K + 45 kg P ha-1. Application of 100 kg K ha-1 + 45 kg P ha-1 was therefore, recommended for profitable sunflower production in the agro-climatic conditions in Northwest Pakistan.sunflower, potassium, phosphorus, oil, protein, economic analysis, Northwest Pakistan, Farm Management, International Development, International Relations/Trade, Production Economics, Productivity Analysis,

Observed galaxy power spectrum in cubic Galileon model

In this paper, we study the effects of general relativistic corrections on the observed galaxy power spectrum in thawing class of cubic Galileon model with linear potential that preserves the shift symmetry. In this scenario, the observed galaxy power spectrum differs from the standard matter power spectrum mainly due to redshift space distortion (RSD) factor and relativistic effects. The RSD term enhances the matter power spectrum both at larger and smaller scales whereas the relativistic terms further enhance the matter power spectrum only at larger scales. In comparison with $\Lambda$CDM, the observed galaxy power spectrum is always suppressed at large scales in this scenario although this suppression is always small compared to the canonical quintessence scenario.Comment: 14 pages, LaTeX style, 7 figures, Comments are welcom

Wakaf Produktif di Negara Sekuler: Kasus Singapura dan Thailand

Dalam Islam beberapa aktifitas yang potensial untuk dikembangkan dalam mengatasi kemiskinan adalah wakaf. Wakaf selain berfungsi sebagi ibadah individual, juga sebagai ibadah sosial. Perkembangan wakaf tidak hanya terjadi pada negara – negara muslim saja tetapi juga pada negara – negara sekuler. Beberapa negara sekuler di kawasan Asia Tenggara adalah Singapura dan Thailand. Hasil penelitian menunjukkan bahwa pertama, manajemen wakaf produktif di Singapura tidak hanya berkontribusi pada masyarakat sosial dan kebutuhan keagamaan, di negara asal mereka dan bahkan manfaatnya dirasakan sampai ke luar negeri seperti India, Yaman, Arab Saudi, dan Indonesia. Kedua, akuntabilitas dan transparansi yang kuat serta budaya muslim Singapura yang baik telah membuat semua aset wakaf dapat diaudit dengan benar. Ketiga, wakaf produktif di Thailand belum memiliki manajemen terintegrasi karena tidak adanya lembaga wakaf independen yang bertanggung jawab mengadministrasikan asset wakaf dan tidak Undang – Undang wakaf yang mengatur hal tersebut di Kerajaan Thailand sehingga asset wakaf sering kali mudah dirampas oleh pihak – pihak tertent

Clash of symmetries on the brane

If our 3+1-dimensional universe is a brane or domain wall embedded in a higher dimensional space, then a phenomenon we term the ``clash of symmetries'' provides a new method of breaking some continuous symmetries. A global $G_{\text{cts}} \otimes G_{\text{discrete}}$ symmetry is spontaneously broken to $H_{\text{cts}} \otimes H_{\text{discrete}}$, where the continuous subgroup $H_{\text{cts}}$ can be embedded in several different ways in the parent group $G_{\text{cts}}$, and $H_{\text{discrete}} < G_{\text{discrete}}$. A certain class of topological domain wall solutions connect two vacua that are invariant under {\it differently embedded} $H_{\text{cts}}$ subgroups. There is then enhanced symmetry breakdown to the intersection of these two subgroups on the domain wall. This is the ``clash''. In the brane limit, we obtain a configuration with $H_{\text{cts}}$ symmetries in the bulk but the smaller intersection symmetry on the brane itself. We illustrate this idea using a permutation symmetric three-Higgs-triplet toy model exploiting the distinct $I-$, $U-$ and $V-$spin U(2) subgroups of U(3). The three disconnected portions of the vacuum manifold can be treated symmetrically through the construction of a three-fold planar domain wall junction configuration, with our universe at the nexus. A possible connection with $E_6$ is discussed.Comment: 30 pages, 9 embedded figure

: The difference increased knowledge and attitudes of mothers about oral hygiene through dental health education lecture with discussion groups and lectures with hands on. Dental health education will be more effective when started from the family by teaching the mothers about the importance of oral health maintenance. This study aims to determine the difference in the increased knowledge and the attitudes of mothers about oral hygiene through dental health education lecture with discussion groups and lectures with hands on. This study was a quasi-experimental design with pretest and post-test group design. The subjects of research were 95 mothers of children aged 6-8 years who met the inclusion criteria and divided into two groups. Group I in PPA IO-497 Benjamin Oebufu, Kupang (53 subjects) were given a lecture with discussion groups and group II in PPA IO-495 Alfa Omega Bakunase 2, Kota Kupang with total of 42 subjects were given a lecture with hands on. Measuring tool was a questionnaire. The analysis of data using Statistic Program for Social Science (SPSS) for a different test testing the T-test for normal distribution of data, while the Mann-Whitney test and the Wilcoxon Signed Rank test were for abnormal distribution data. The initial analysis on knowledge and attitudes obtained some comparable results in which there were no differences between treatment groups I and II (p > 0.05). The results of the analysis of mean differences between groups on post-test 1 and 2 showed some significant differences knowledge and attitudes in the treatment group II of the treatment group I (p < 0.05). The results of the analysis of the average increase showed the increased knowledge and attitudes were significant in both treatment groups. Delta analysis results from pre-test to post-test 1 and pre-test to post-test 2 showed the treatment group improved knowledge and attitudes II is higher than in the treatment group I (p < 0.05).

The Inter-Mammary Sticky Roll: A Novel Technique for Securing a Doppler Ultrasonic Probe to the Precordium for Venous Air Embolism Detection.

Venous air embolism is a devastating and potentially life-threatening complication that can occur during neurosurgical procedures. We report the development and use of the "inter-mammary sticky roll," a technique to reliably secure a precordial Doppler ultrasonic probe to the chest wall during neurosurgical cases that require lateral decubitus positioning. We have found that this noninvasive technique is safe, and effectively facilitates a constant Doppler signal with no additional risk to the patient

Goal-directed versus outcome-based financial incentives for weight loss among low-income patients with obesity: rationale and design of the Financial Incentives foR Weight Reduction (FIReWoRk) randomised controlled trial.

IntroductionObesity is a major public health challenge and exacerbates economic disparities through employment discrimination and increased personal health expenditures. Financial incentives for weight management may intensify individuals' utilisation of evidence-based behavioural strategies while addressing obesity-related economic disparities in low-income populations. Trials have focused on testing incentives contingent on achieving weight loss outcomes. However, based on social cognitive and self-determination theories, providing incentives for achieving intermediate behavioural goals may be more sustainable than incentivising outcomes if they enhance an individual's skills and self-efficacy for maintaining long-term weight loss. The objective of this paper is to describe the rationale and design of the Financial Incentives foR Weight Reduction study, a randomised controlled trial to test the comparative effectiveness and cost-effectiveness of two financial incentive strategies for weight loss (goal directed vs outcome based) among low-income adults with obesity, as well as compared with the provision of health behaviour change resources alone.Methods and analysisWe are recruiting 795 adults, aged 18-70 years with a body mass index ≥30 kg/m2, from three primary care clinics serving residents of socioeconomically disadvantaged neighbourhoods in New York City and Los Angeles. All participants receive a 1-year commercial weight loss programme membership, self-monitoring tools (bathroom scale, food journal and Fitbit Alta HR), health education and monthly check-in visits. In addition to these resources, those in the two intervention groups can earn up to $750 over 6 months for: (1) participating in an intensive weight management programme, self-monitoring weight and diet and meeting physical activity guidelines (goal-directed arm); or (2) a ≥1.5% to ≥5% reduction in baseline weight (outcome-based arm). To maximise incentive efficacy, we incorporate concepts from behavioural economics, including immediacy of payments and framing feedback to elicit regret aversion. We will use generalised mixed effect models for repeated measures to examine intervention effects on weight at 6, 9 and 12 months.Ethics and disseminationHuman research protection committees at New York University School of Medicine, University of California Los Angeles (UCLA) David Geffen School of Medicine and Olive-View-UCLA Medical Center granted ethics approval. We will disseminate the results of this research via peer-reviewed publications, conference presentations and meetings with stakeholders.Trial registration numberNCT03157713

Non-Abelian Monopole and Dyon Solutions in a Modified Einstein-Yang-Mills-Higgs System

We have studied a modified Yang-Mills-Higgs system coupled to Einstein gravity. The modification of the Einstein-Hilbert action involves a direct coupling of the Higgs field to the scalar curvature. In this modified system we are able to write a Bogomol'nyi type condition in curved space and demonstrate that the positive static energy functional is bounded from below. We then investigate non-Abelian sperically symmetric static solutions in a similar fashion to the `t Hooft-Polyakov monopole. After reviewing previously studied monopole solutions of this type, we extend the formalism to included electric charge and we present dyon solutions.Comment: 18 pages LaTeX, 7 eps-figure
