We address in this memo the ability of ALMA to observe stars and extrasolar planetary systems (in various stages of formation). The observation of extrasolar planetary systems is thought to be one of the most important science drivers for ALMA. As such, we should have some idea of what the capabilities might be in this regard. In addition, ALMA will be the first instrument which will be able to...
ALMA will revolutionize the study of star formation by providing a combination of angular resolution and sensitivity that far exceeds that of present instruments. I will focus on studies of relatively isolated cores that are forming low-mass stars. There is a general paradigm for the formation of such stars, and there are detailed theoretical predictions for the evolution of the density and vel...
this study investigated the relationships between nutrients and chlorophyll, a concentration in the international alma gol wetland. chlorophyll a is the major photosynthetic pigment in lots of phytoplanktons and has been used as a trophy index in aquatic ecosystems. water samples were collected fortnightly from five stations in the wetland during summer and autumn. chlorophyll-a ranged between ...
In the first of 5 papers about health systems and services in the Arab countries, the historical development of health systems over the past 3 decades is reviewed. The evolution of health care has been impressive with major strides accomplished by governments to improve the health status of their respective population. However, the progress has been uneven in view of the differentials in resour...
Primary health care was conceived in the 70s as a comprehensive, joint and inclusive strategy to achieve the goal of "Health for Everyone". It was the result of important social, political and economic changes which occurred at global level back in those years and which persist until now. Due to an unfortunate combination of words, Primary Healthcare has been mistakenly understood by many as "h...
The celebration in Doha of the 30th anniversary of the Alma-Ata Declaration at the International Conference on Primary Health Care renewed the commitment of the Eastern Mediterranean Region to primary health care as the tool for better health. The principles agreed at Alma-Ata in 1978 apply as much now as they did before. The event provided an opportunity for the Eastern Mediterranean countries...
A cost-beneet analysis for ALMA conngurations is conducted based on the previous analysis of the MMA conngurations by Holdaway (1998). In particular, the impacts of having a larger number of antennas and longer baselines on the overall array eeciency are addressed along with several practical concerns that may aaect the connguration plan.
In 1978 at Alma Ata, Malaysia endorsed the World Health Organization's Declaration of Health for All through Primary Health Care. Since then Malaysia has made great strides in meeting its objectives. There is now an expanded scope of services with better facilities in the public community polyclinics. Primary Care departments have been established in the local universities, either independently...
We study the prospects of finding the first quasars in the universe with ALMA and JWST. For this purpose, we derive a model for the high-redshift black hole population based on observed relations between the black hole mass and the host galaxy. We re-address previous constraints from the X-ray background with particular focus on black hole luminosities below the Eddington limit as observed in m...
We present new Atacama Large Millimeter/Submillimeter Array (ALMA) 850 μm continuum observations of the original Lyα Blob (LAB) in the SSA22 field at z=3.1 (SSA22-LAB01). The ALMA map resolves the previously identified submillimeter source into three components with a total flux density ofS850=1.68±0.06 mJy, corresponding to a star-formation rate of ∼150Me yr. The submillimeter sources a...
