Angular Eigenvalues of Higher-Dimensional Kerr-(A)dS Black Holes with Two Rotations

In this paper, following the work of Chen, L\"u and Pope, we present the general metric for Kerr-(A)dS black holes with two rotations. The corresponding Klein-Gordon equation is separated explicitly, from which we develop perturbative expansions for the angular eigenvalues in powers of the rotation parameters with $D\geq 6$.Comment: 10 pages, no figures.

Growth and Productivity of Irrigated Rice (Oryza sativa L.) for a Tropical High Altitude Environment in Rwanda

Yield components, grain yield, biomass and plant N accumulation, and N fertilizer responses of irrigated rice (Oryza sativa, L.) were evaluated for a tropical inland valley environment in the high altitudes in Rwanda. Effects were measured for nitrogen (N) fertilizer rate (0, 60, 90,120,150,180 kg N ha-1), season, growth stage and cultivar of different subspecies and plant types during 2012 dry season (DS) and 2013 wet season (WS) at Cyili Rice Research Farm (1380 m above sea level). Variations in irradiance (17.2± 0.32 MJ m-2 day-1 in DS and 9.4 ± 0.66 MJ m-2 day-1in WS) were linked to seasonal differences in biomass and closely related to N responses, yield components and the grain yields which were greater in the DS (9.0 t ha-1) than in the WS (5.3 t ha-1). Total plant N uptake was in the same range (200 to 250 kg N ha-1) for both seasons at maturity. Grain yields were highly correlated (r2 = 0.89) to yield components and mostly with the number of spikelets per panicle (r2 = 0.70) and spikelets per m2 (r2 = 0.80). In most cases, yield components were equivalent or greater to the potential under irrigated lowlands in the tropics of Asia and the highest farm yields (8 to 10 t ha-1) in the temperate. Rice genotypes of Indica x Japonica subspecies combinations were overall greater in yield, harvest index and in important yield components. Crop growth rate (CGR) over seasons and cultivars was 11g m-2 day-1 at maturity. The average total crop duration of 145 days may be considered as the current optimal for achieving the yield potential obtained in the irrigated lowlands of the tropics in Asia. Responses to N fertilizer addition were generally minimal with most measured attributes maximized when the lowest N rate of only 60 kg N ha-1 was applied. This suggested a large contribution from the native soil N reserves linked to ample amounts of total soil N (2.80 ± 0.34 g kg soil-1). The Indica x Japonica combinations may represent a cultivar improvement strategy for greater adaptation and grain yield and quality in Rwanda

HIV and tuberculosis co-infection in East Asia and the Pacific from 1990 to 2017: Results from the Global Burden of Disease Study 2017

Background: Periodic surveillance is crucial to provide information for resource allocation to control HIV/AIDS, tuberculosis (TB), and their co-infection, especially in areas with high morbidity and mortality like East Asia and the Pacific. Therefore, we examined the morbidity and mortality of HIV/AIDS and TB co-infection in this region from 1990 to 2017. Methods: Utilizing the Global Burden of Disease (GBD) Study 2017, we obtained incidence, prevalence, and mortality numbers and rates of HIV/AIDS and TB co-infection, including HIV and drug-susceptible TB (DS-TB), multidrug-resistant TB without extensive drug resistance (MDR-TB without XDR), and extensive drug-resistant TB (XDR-TB). The trends in incidence, prevalence, and mortality from 1990 to 2017 for each co-infection type were analyzed using join-point regression modelling. Results: In 2017, there were 238,372, 4,294, and 392 new cases of HIV-infected DS-TB, HIV-infected MDR-TB without XDR, and HIV-infected XDR-TB, respectively. The number of prevalent cases and deaths were 383,809 and 12,197 of HIV-infected DS-TB, 7,811 and 1,168 of HIV-infected MDR-TB without XDR, and 713 and 282 of HIV-infected XDR-TB. From 1990 to 2017, the age-standardized incidence rate and prevalence rate of HIV-infected DS-TB, and the prevalence rate of HIV-infected XDR-TB continuously increased; the incidence rate of HIV-infected XDR-TB increased from 1990 to 2005 before stabilizing. However, the incidence and prevalence rates of HIV-infected MDR-TB without XDR-as well as the mortality rates of all co-infection types-have decreased in the last 5 years. Conclusions: Even though the mortality rates of all HIV and TB co-infection types have decreased recently, the overall trends in both incidence and prevalence rates of HIV-infected DS-TB and XDR-TB have been increasing since 1990. Efforts to control co-infection across drug resistance types should be continued and further strengthened

Mapping of household vulnerability and identification of adaptation strategies in dryland systems of South Asia, Research Report No. 67

Low amount and high variability of rainfall in South Asian dryland production system have affected the livelihood of small and marginal households. Therefore, a marginal change in the climate could challenge the livelihood resilience of millions of farmers and affect the healthy ecosystem function in South Asia. The CGIAR Consortium Research Program on Dryland Systems (DS) focuses on DS across the world in order to tackle these problems. The overall emphasis of the research involves understanding the problem, identifying and demonstrating technologies and searching for mechanisms to promote the adoption of promising technologies. In South Asia, the program selected six districts in Andhra Pradesh (Anantapur and Kurnool), Karnataka (Bijapur) and Western Rajasthan (Jaisalmer, Barmer, and Jodhpur) as action sites..

Paleomagnetic Study of Mesozoic Continental Sediments Along the Northern Tien Shan (China) and Heterogeneous Strain in Central Asia

A paleomagnetic study of rocks from the northern foot of the Tien Shan and the southern border of the Dzungar Basin, east of Urumqi (44.2°N, 86.0°E), spanning ages from middle Jurassic to early Tertiary was carried out to constrain the tectonic evolution in central Asia since Mesozoic time. Five middle Jurassic sites reveal a remagnetized direction close to the present Earth field in geographic coordinates: D = 6.6°, I = 72.6° (α_(95) = 7.4°). Thirteen out of 17 upper Jurassic and lower Cretaceous sites yield a characteristic direction (stratigraphic coordinates) of D = 12.7°, I = 48.6° (α_(95) = 5.5°). Nine of 16 upper Cretaceous and lower Tertiary sites provide a characteristic direction of D = 12.5°, I = 51.3° (α_(95) = 6.9°). The latter two directions pass fold and reversal tests. The pole positions are close to each other and to the Besse and Courtillot [1989, 1990] Eurasian apparent polar wander path, for ages ranging from 130 to 70 Ma. However, the difference in paleolatitudes amounts to about 5.9° ± 3.7°, which could indicate significant continental shortening in the Altai Mountains and perhaps further north, subsequent to India-Asia collision. The pole positions from the Dzungar Basin are close to those found for the Tarim [Li et al., 1988a], leading to an insignificant paleolatitude difference (3.0° ± 6.9°), but showing a larger difference in declination (8.6° ± 8.7°). These paleomagnetic results are compatible with a model of heterogeneous deformation in the western part of the collision zone between India and Siberia. A significant shortening in the Altai, a slight counterclockwise rotation of the Dzungar block, the westward-increasing shortening in the Tien Shan with attendant clockwise rotation of the Tarim block are all consistent with this model, in which Tibet, the Tien Shan and the Altai undergo differential strain along strike in a relay fashion, with the total India-Siberia convergence remaining approximately constant

This review summarises the methodologies and main outcomes of longitudinal studies of pre-school children (0 to 59 months) in the World Health Organization’s South East Asia (SEA) and Eastern Mediterranean (EM) Regions

Report on a collecting trip of the British Myriapod Group to Hungary in 1994

During a collecting trip participated jointly by the members of the British Myriapod Group and by Hungarian experts in 1994, 34 species of millipedes, 14 of centipedes, 8 of woodlice and 73 of spiders were recorded from Hungary. Two records of the millipede species Boreoiulus tenuis (Bigler, 1913) and Styrioiulus styricus (Verhoeff, 1896) were new to the fauna of Hungary

THE WORLD ECONOMIES AND DEVELOPMENT GOALS:AN ARCHITECTURAL POLICY FRAMEWORK

DEVELOPMENT IS THE MOST IMPORTANT CHALLENGE FACING THE HUMAN RACE BUT THE PROCESSES DRIVING ECONOMIC DEVELOPMENT ARE BY NO MEANS FULLY UNDERSTOOD. HOWEVER, THE CORE CHALLENGE FOR DEVELOPMENT IS TO ENSURE PRODUCTIVE WORK AND A BETTER QUALITY OF LIFE FOR ALL THE PEOPLE OF THE WORLD. THIS CHALLENGE MAY BE DAUNTING AND IT IS. THIS PAPER THEREFORE ARGUES THAT A GLOBAL ECONOMIC ARCHITECTURE IS IMPERATIVE FOR THE ATTAINMENT OF THE UNITED NATIONS MILLENNIUM DEVELOPMENT GOALS WITHIN A FRAMEWORK OF THE MUTUAL IMPACT OF DEVELOPED AND DEVELOPING WORLDS. AND WITHIN THE EMERGING NEW ECONOMIES, DEVELOPMENT MUST FOCUS ON ACHIEVING KNOWLEDGE-INTENSIVE DEVELOPMENT OR E-DEVELOPMENT(WITH CULTURAL INCLUSION).world economy, development goals, africa, north america, south america, antarctia, asia, oceania, europe, income poverty, education, hunger, hiv/aids

Global Employment Trends for Youth: October 2008

[Excerpt] An intensified focus on youth at the international level in recent years has brought a greater understanding of youth labour markets and led to development of a growing number of national action plans for youth employment as well as other more specific youth-related policies and programmes at the national level. But has the increased global awareness of the vulnerabilities of youth brought about any quantifiable changes in their labour market situation? Are more young people attaining their desired job? The ILO\u27s third edition of the Global Employment Trends for Youth (October 2008) examines the most recent labour market indicators and finds that young people still suffer disproportionately from a deficit of decent work opportunities. However, progress has been seen in some regions. The report, which updates the world and regional youth labour market indicators presented in previous reports (2004 and 2006), is organized according to nine regional analyses
