Obesity Major Problem

Obesity Major Problem
Obesity is a major health problem in North America and several European countries. Currently over half of the total population living in the United States is thought to be having either overweigt or obesity. Incidence of obesity continue to increase in both males and females. Of all U.S. women twenty years and older, about 64 million can be considered as overweight and more than 34 million are will fall in to the catagory of obese women.

Obesity is associated with significant health hazards and increase death rates. Obese individuals are more suseptible to suffer from coronory artary disease, type 2 diabetes, hypertension, cerebrovascular events and a host of other medical conditions. It is very important that we all eat healhy food and routinely maintain a program of physical activity througout life. To lose weight and keep it off over time, try making long-term modifications in your dietery and physical activity habits.

Measuring the exact amount of a person's body fat level is not easy. The most accurate measures of body fat are weighing a person underwater or inside a chamber that uses the principle of air displacement to estimate body volume, or to use an X-ray technique called DEXA. Body fat mesaurements need not be so complex. There are many simpler methods to estimate fat content of the body. One is to measure the thickness of the fat layer just under the skin in several parts of the body. Another involves passing a small amount of electricity through a person's body. Results from these methods, can however be, less than accurate especially if done by an inexperienced person or on someperson with high level of obesity.........

Go To Church To Breathe Easier

Go To Church To Breathe Easier
Going to church might help you breathe easier. A new study by Temple Universitys Joanna Maselko, Sc.D., observed that religious activity may protect and maintain pulmonary health in the elderly.

Pulmonary function is an important indicator of respiratory and overall health, yet little is known about the psychosocial factors that might predict pulmonary function. At the same time, religious activity is emerging as a potential health promoting factor, particularly among the elderly. We wanted to determine whether there was a correlation between the two, Maselko said.

Religious Service Attendance and Decline in Pulmonary Function in a High-Functioning Elderly Cohort, reported in the November 2006 issue of the Annals of Behavioral Medicine, was conducted while Maselko, assistant professor of public health, was at Harvard University.

Using peak expiratory flow rate (PEFR), scientists measured pulmonary function in 1,189 study subjects ranging in age from 70 to 79 years. They observed that.

regular religious service attendance (at least weekly attendance) was linked to a slower pulmonary function decline among men and women, in comparison to those who never attend services. The findings could not be explained by differences in smoking or physical activity.........

World's Oldest Ritual Discovered

World's Oldest Ritual Discovered In the excavation they found more than 13,000 artifacts

A startling archaeological discovery this summer changes our understanding of human history. While, up until now, scholars have largely held that mans first rituals were carried out over 40, 000 years ago in Europe, it now appears that they were wrong about both the time and place.

Associate Professor Sheila Coulson, from the University of Oslo, can now show that modern humans, Homo sapiens, have performed advanced rituals in Africa for 70,000 years. She has, in other words, discovered mankinds oldest known ritual.

The archaeologist made the surprising discovery while she was studying the origin of the Sanpeople. A group of the San live in the sparsely inhabited area of north-western Botswana known as Ngamiland.

Coulson made the discovery while searching for artifacts from the Middle Stone Age in the only hills present for hundreds of kilometers in any direction. This group of small peaks within the Kalahari Desert is known as the Tsodilo Hills and is famous for having the largest concentration of rock paintings in the world.

The Tsodilo Hills are still a sacred place for the San, who call them the Mountains of the Gods and the Rock that Whispers.

The python is one of the Sans most important animals. According to their creation myth, mankind descended from the python and the ancient, arid streambeds around the hills are said to have been created by the python as it circled the hills in its ceaseless search for water.........

Placement Of Rainforest Trees

Placement Of Rainforest Trees
The apple might not fall far from the tree, but new research shows that how it falls might be what is most important in determining tree distribution across a forest. This study of the seed dispersal methods of rainforest trees demonstrates that these methods play a primary role in the organization of plant species in tropical forests.

Joshua B. Plotkin, a junior fellow in the Faculty of Arts and Sciences at Harvard University, and co-author Tristram Seidler will publish their results in the recent issue of the journal Public Library of Science Biology.

"Overall, there is a highly significant relationship between mode of seed dispersal and the clustering and arrangement of mature trees in the rainforest," says Plotkin. "This strong correlation demonstrates the long-term impact that these dispersal methods have on the organization of the large-scale forest".

In order to address the paradox of how so many rainforest species can coexist while competing for the same resources, Plotkin and Seidler studied a 50-hectare (500 meters by 1,000 meters) plot of lowland tropical forest at Pasoh Forest Reserve in peninsular Malaysia. They analyzed the dispersal mechanisms and spatial distributions of 561 tree species found in the plot. What they found was that species clustering was strongly correlated to the species' mode of seed dispersal.........

Public School Or Private School

Public School Or Private School
In the first study to examine differences in learning gains at the kindergarten level, William Carbonaro (University of Notre Dame) finds that publicly schooled kindergarteners post the same or greater learning gains than privately schooled kindergarteners. These findings come as a surprise because, as Carbonaro writes in the recent issue of the American Journal of Education, Both the financial costs of private schooling and other self-selection factors ensure that the private schools will have a more advantaged population of students than public schools.

Using data from the Early Childhood Longitudinal Study, Carbonaro points out that gains at higher academic levels are greater among privately schooled students. On the one hand, it is reassuring that public kindergartens do as well or slightly better than private kindergartens in producing learning gains, Carbonaro writes.

On the other hand, this remains something of a hollow victory because private school students still have substantially higher test scores at the end of kindergarten than public school students.

Carbonaro suggests that public schools may want to seriously consider instituting all-day kindergarten to catch up to private school achievement levels, as this would provide more learning opportunities without reducing the amount of time spent in school on nonacademic material.........

Survival Of Many Universities At Risk

Survival Of Many Universities At Risk
The survival of many developing country universities, especially in Africa, is at risk if they are not quickly strengthened and geared to help address regional development problems through research, warns the head of advanced studies at the United Nations University.

Speaking at UNESCOs Paris headquarters Nov. 29, Prof. A.H. Zakri, Director of UNUs Yokohama-based Institute for Advanced Studies, appealed for international help to foster relevant research programmes in the developing world, where the pressures are greatest, the need most acute and it is really a matter of life and death.

Many developing country universities are not relevant, he says, citing Dutch research showing a major disconnect between research in developing country universities and regional economic development priorities, as well as weak linkages between knowledge producers and users and between knowledge production and innovation.

A universal characteristic of university success is relevance or research utility, says Dr. Zakri. Universities and the research they undertake needs to be relevant to their Governments policy, to their peoples educational needs and to their communitys needs. Universities that are not relevant will not survive.

He told an international conference of higher education experts that rising poverty, falling Gross Domestic Product and political upheaval in Africa are a function in part of paltry national R&D investment through universities in that part of the world. According to Dr. Zakri, Asia accounted for 31.5% of world R&D expenditure in 2001; Africa accounted for 0.6%.........

Venturi Eclectic car

Venturi Eclectic car
This interesting article is worth discussion:

I was once called the "Gay Inspector Gadget" (don't ask). You see I have this belief that the perfect car for me will be laden with gadgets, keep me connected to the world and have a neutral impact on the environment. Aside from the gadgets thing, I don't see anything else I have in common with Inspector Gadget. I mean I don't have a little blond girl shadowing me with a brainy dog, so the reference has always eluded me.

Until a friend of mine emailed me a link to a the Venturi Eclectic with the subject heading "Here's your car Inspector!". You're real funny Rui, real funny. I still don't see the reference but the vehicle intrigues me.

The Eclectic is billed as the world's first mass produced energy autonomous vehicle. It's designed for daily driving in urban areas and is powered by electricity via 3 sources; plug-in, solar and wait for it. wind. The roof is equipped with the advance photovoltaic cells to quickly harness the power of the sun keeping you juiced and ready to go. To support that system is a wind turbine that extends up and out capturing the power of wind should there be a gust and both are augmented with an advance plug-in system for those overnight recharges.........

Old Engravings Of Animals Are Charmingly Strange

Old Engravings Of Animals Are Charmingly Strange
Mark Frauenfelder:

Bibliodyssey has an excellent gallery of 18th century engravings from 'Die Saugthiere in Abbildungen' at Ecole Nationale Veterinaire de Lyon (named as 'Histoire naturelle des quadrupedes'.

The absurd rendering of a number of of the animals comes about because the engravers/artists working on the project did not actually see the animals. They had to rely on descriptions and their imagination and, as was the fashion of the time, the animals were placed in contrived settings and often given human facial qualities, which only serves to heighten the sense of bizarre. And thankful we are too.........
