Indian researchers convert textile waste into rich manure VERMI COMPOSTING


July 17th, 2009

HISSAR - Earthworms and some animal manure could convert waste from the textile industry into a rich compost for agriculture, researchers here have found.

Most gardeners will tell you earthworm is their best friend as it aerates the soil and helps break down the soil materials, releasing nutrients for improved plant growth.

A particular species of earthworm, known as Eisenia foetida, thrives in rotting vegetation, compost, and manure. This species is grown commercially for composting because of its skills at converting organic waste into rich compost.

Vinod Garg, Renuka Gupta and Priya Kaushik of Guru Jambheshwar University of Science and Technology here say the red earthworms could be used to produce compost from the huge volumes of solid sludge produced by the textile industry.

Sludge from the textile industry is usually difficult to dispose of. Landfill and incineration are not viable options given environmental concerns and expense. The industry is under pressure to find a green, sustainable and cost-effective disposal method.

Garg and colleagues have now tested vermicomposting of solid textile mill sludge that has been spiked with urine-free cow and horse dung, collected from local farms, in a six-month pilot-scale experiment using E. foetida.

The composting process changes the physical and chemical properties of the test mixtures significantly, the team found. The vermicomposts are much darker than the original materials and form a compost-like, homogeneous mixture after 180 days.

The team also found that the earthworms grow well in this manure-enhanced sludge, said a release of the university.

These findings were published in the International Journal of Environment and Pollution.

attached growth airlift reactor (Agar) solution in South Africa

Israeli firm launches wastewater treatment solution in SA
24th July 2009
Israeli wastewater treatment solutions provider Aqwise has launched its
patented attached growth airlift reactor (Agar) solution in South Africa,
exploring for opportunities in the promising local market.

Aqwise is an advanced wastewater treatment solutions provider for the
industrial and municipal markets.

The Agar technology integrates fixed filmed and suspended growth
technologies and is considered the next generation in biological wastewater
treatment methods. The Agar technology combines a distinctive, fully open
and fully protected moving biomass carrierwith a highly efficient aeration
and mixing design. This results in a greater effective surface area for
biomass growth and the best oxygen transfer efficiency.

If an industrial plant is required to produce a higher-quality effluent
owing to increased regulatory requirements or the implementation of
water-saving measures, the Agar solution alters the biological environment.

This creates optimal conditions for enhanced removal of a wide variety of
pollutants, including organic load and nitrogen.

Aqwise business development manager Idan Tendler tells Engineering News that
the Agar technology significantly increases the capacity and efficiency of
existing wastewater treatment plants, while reducing the size of new plant

The Agar system also has a limited footprint, making it a good solution for
industrial plants or municipalities that have limited spaceand are unable to
expand. "The solution offers significant space efficiencies in the
implementation of new reactors with a 30% to 60% reduction in reactor volume
when compared with conventional systems," says Tendler.

He explains that, by using Aqwise's solutions, mines and municipalities can
cope with more stringent water-sector regulation, ageing infrastructure and
a growing population. Industrial plants can meet the strict regulatory
requirements for discharging wastewater into the environment or into
municipal collection systems, and solve typical industrial problems, such as
variable inflow, seasonal peaks and high organic loads.

"The solutions may additionally facilitate in-plant reuse of the treated effluent with up to zero liquid discharge," he says.

Tendler explains that the Aqwise range of solutions may be applied to any
type of bio-logical process upgrade, including existing oxidation ponds and
activated sludge.

Further, the Agar technology can avoid or significantly decrease sludge
circulation, reducing the ongoing operation attention needed. "This makes
the system ideal for industrial plants with limited wastewater treatment
operations resources and minimal ongoing attention," he says.

Aqwise's technology is also currently being tested in reducing the amount of
iron in ground-water being released by mines into the environment.

mechanical composting..its problems

Almost all the large cities of the developing countries in the region in the past installed imported mechanical composting plants (for instance, built six). Most are now defunct and the remaining ones are not operating at full capacity (e.g., Bangkok, Hanoi, Shanghai, and Tokyo). The reasons why centralized mechanical MSW composting plants are not functioning effectively, are underutilized, or are closed down include: (a) high operating and maintenance costs compared to open landfilling (including foreign exchange costs for replacement parts of imported plants); (b) the cost of compost is higher than commercial fertilizers (both cost to purchase, and labor cost to apply to the fields); (c) incomplete separation of materials such as plastic and glass, making the compost poor for agriculture application; and (d) poor operation and maintenance of the facilities.

There are many technical and aesthetic problems to be solved in the composting of MSW. As one small example, an important, privately run vermiculture experiment in Indonesia failed when toxics in the MSW killed the earthworms.

Composting can be viable, especially for smaller cities with intensive agricultural areas near cities. Many international agencies and environmental consulting firms are offering Asian cities technology for composting as the process is increasingly gaining importance in all parts of the world. An issue here is whether the equipment offered is appropriate for the wastes of that particular place

Although one of New Delhi's plants has been closed, another is still operating. The compost is absorbed by the city's parks department, an example of how city procurement policies can help the marketing problem. In Kathmandu, the compost from a municipal plant was in high demand by local farmers in the late 1980s and early 1990s, and the plant continued with a simple windrow system after the machinery broke down. It was forced to close recently when residents of new housing estates protested.

Recently, however, private firms, alone or in public-private partnership, have revived centralized composting in a few places. Bangalore's windrow compost plant is reported to be cost-effective since privatization, although there are now NIMBY ("Not In My Back Yard") pressures at the site. There are experiments with new techniques for producing compost by processing partly decomposed wastes at dump sites (being done by a private company subsidized by the Bombay and Ahmedabad municipal corporations).

The subcontinent has wide experience with anaerobic digestion of cattle dung, and it was assumed that similar digesters could be adapted to ferment MSW, but producing animal-dung-like slurries from urban organic waste proved energy-intensive and the product was poor. A major problem with anaerobic digestion is that MSW used as feedstock tends to float. A number of design changes have to be achieved to produce small-scale digesters. Research is being done in Bangalore at the Indian Institute of Science, but there are no reports of successful large-scale anaerobic digestion.

Finding it hard to conceive? Try Gourmet Sex

Have you been trying to conceive, but ended up feeling completely demoralised at the non results? For a lot of couples desperate to have a child,
Finding it hard to concieve? Try Gourmet Sex
sex has been reduced to a high stress zone where the goal is ovulation rather than sexual pleasure.

Recent research is however saying that the best way to get pregnant is to adopt the old-fashioned approach - wild passionate sex like you did it when you first dated. Fertility experts have coined the term 'gourmet sex' - where the couple focuses on a satisfying experience, rather than just getting pregnant as the ultimate fertility treatment.

Experts feel that the sex should be as wild and thrilling as it was when the couple first got together, when they weren't obsessed with conceiving. An extra five minutes of foreplay before ejaculation can produce an extra 25 million sperm, according to experts. The more excited sperm will also be of a higher standard, meaning there is a greater chance of the sperm and egg fusing to create a new life.
Here's how you can enjoy gourmet sex:

1. Stop focusing only on sex; rather make time out to improve the quality of your relationship. Share fantasies and issues that you may have with each other. Communication is key in enjoying a happy relationship. Unleashing a fantasy adds a new dimension to your relationship, heightening the novelty-factor. Always discuss your sexual desires and don't ridicule a partner's fantasies. This will help in feeling more liberated in your relationship. Don't take each other for granted, compliment each other and try and overlook each others' short-comings. If your partner is looking fat in a sexy nightie, don't shun them, tell her how you love her curves and then gently say, 'honey, let's join a gymn together.' It will not shatter her confidence.

2. Preparation is integral before a satisfying sex romp. Always have a sensuous shower before you have sex. Pamper yourself so that you are feeling your best making love knowing. Also, invest in sexy lingerie, opting for silky innerwear that feels soft against the skin. A recent survey claimed most men found their women sexiest in a football or rugby shirt, so it's not so much what you wear, but how you put a look together with confidence that turns on a man. Move sensuously, because a woman's gait and eye contact is vital in making a man want him.

3. Before your big night, avoid a huge meal, lots of alcohol or any gas-inducing foods. Too much alcohol mars performance and spicy or too much food might give you gas.

4. Focus on foreplay. Read each other erotic stories. Dim the lights and switch off your cell phones and then whisper lines from the book into your lover's ear. They are sure to feel turned on as they hear you relate the scenario. It's bound to pre-empt the sexual high. Or try and pen your own erotic story to read to your beau. Act out certain imaginary chapters.

5. Make foreplay as adventurous as possible. Concentrate on the less obvious body parts. Make time to explore erogenous zones, such as the neck, nipples, back of the knees. Stroke with a feather, fingers, tongue or other body parts.

6. Blindfold your lover or let them blindfold you and dab some honey or chocolate sauce, somewhere on your body. Let your partner lick off the sweet juices using only their tongue. Exploring your body gives then a great opportunity to know you intimately.

7. Decorate your body in a variety of tasty foods, such as sliced strawberries, ice cream or melting chocolate. Invite your lover to dine out on you, starting with your sensitive areas such as the neck and your ankles.

8. Gourmet sex is about having fun , so both of you should give directions and be directed. Tell your partner exactly what you want them to do. Try out new sex moves, new places that lie beyond the bedroom that help you achieve a sexual high better than you have even imagined.

Sex-guide according to your age

The missionary position. Or man-on-top is said to be the position that's best for getting pregnant. This is because this particular position allows for the deepest possible penetration, making it possible for the sperm to get deposited closest to the cervix. place her legs over your shoulders. This shortens her vaginal canal, so your penis feels bigger inside her.

Raise the hips. 
Elevating the hips, which can be done by placing a pillow behind her, can also be helpful because this exposes the female cervix to as much semen as the male can release. 

Orgasms. Finally, while this has nothing to do with sexual positions, there are also researches that suggest the importance of the female orgasm in conceiving. According to studies, female orgasm leads to contractions that could push sperm up into the cervix. The lesson: have fun while trying to conceive. 
Q: Is male infertility a serious threat?
A: It accounts for 40 per cent of all infertility, primarily due to sperm defects. Sometimes this is brought on by external factors like tight innerwear, very hot baths, smoking, exposure to radiation and toxic chemicals. Sometimes there's a physiological basis-diabetes, hypothyroidism or genetic aberrations.
Q: What about infertility in women?
A: I see many young women who show signs and symptoms of polycystic ovaries, a condition associated with metabolic disorders and obesity. From job pressure to vehicular pollution, postponing parenthood to sexual liberation, fast food to sedentary lifestyle, all have been linked to infertility.
Conception Timeline
A: woman's fertility peaks between age 27 and 34. That's the best time to have the first baby. The best time to get pregnant? Watch out for the narrow window of time during ovulation, two weeks into the menstrual cycle. The life of a human egg is about 36 hours, while a sperm can survive in a woman's body for about 48 hours.

30% more chances of conception every month if a couple engages in unprotected sex at least two times a week.
Myth : Daily sex increases chances of pregnancy
Reality : No it doesn't. It may, in fact, bring down sperm count on the day of ovulation.

Most guys just can't stop dreaming about sex every couple of hours. At this age, girls are usually rebellious in their sexual imaginations. They share same-sex fantasies or want to try out bi-sexuality. A 2006 study of nearly 2000 people discovered that 76 per cent of women who slept with women reached orgasm (for women with men, the figure stands at 50 per cent).
The 20s are the time when young boys and girls are most experimental in their sexual positions. One in 10 people claims Tracey Cox have had a threesome in their early twenties.

Also, people in this age group have most likely visited a strip joint or a lapdancing club - with their friends or their better half.

30 something
The 30s are a time to experiment, almost all 30-somethings claim to have had sex outdoors. Unlike the teens when making out was the most common form of sexual experimentation, most 30 somethings prefer having sex somewhere semi-public like the beach, in the garden or on a park bench in the darkness. There's something wildly erotic about these sexapades! Also, high on the 30 something popularity chart are having sex in the shower or in the bath tub.

Kinky pleasures also rate high as most 30 plus couples claim to be giving in to their fantasies of bondage, blindfolds and spanking on a weekend of debauchery.
This is also the time when women are most likely to befriend gay male pals. Straight women love gay men; gay men love straight women. Swedish research is confirming just why the two groups get along so famously - they both have symmetrical brains. Straight men and lesbians have asymmetrical brain hemispheres.

The 30s also mark the arrival of children in a married couple's life, so the sex drive naturally dwindles. But, Cox points out that during pregnancy, couples have sex four to five times a month. Most put the brakes on their sex lives for about seven weeks after delivery, but four months later are back to four or five times of sex a month. Cox says six months after delivery, the average couple goes back to having sex three to five times a month. But incase you don't fit the bill, remember getting disheartened ain't gonna help. Remember it's just a temporary period, so continue touching and cuddling and if your baby robs you of chances to have sex, indulge in quickies.

Most women says Cox in her book experience higher orgasm rates. Ninety per cent of women past 30 regularly experience orgasm, compared to just 23 per cent of younger women.

40 something
Men in their 40s are more likely to experience erection problems. Also, this is the age when maximum number of men tend to be unfaithful. Also, men are more compelled in their 40s to watch more porn or indulge in sex chats. Women on the other hand get sexually very demanding, often being attracted to younger men.

If you thought the 40s were about low libido, think again, while 40-somethings maybe having less sex than ever, the thrust has shifted from how many times in a week to an emphasis on better quality. You are more sure of your sexual needs in this age group and thus more likely to insist on passion play as opposed to a mere making out session.

"MILF" is the most frequently searched porn term on the Internet.

Research has proven that men tend to focus more on the face of the woman while watching porn.

Being sympathetic, kind, co-operative and warm may lower men's likelihood of becoming bosses

Being sympathetic, kind, co-operative and warm may lower men's likelihood of becoming bosses, according to a study.

The same may also apply to women to a certain extent, say the researchers behind the study.

According to reports, this study has provided firm evidence of the link between personality and job choice.

"People who aren't very nice are more likely to become managers," quoted study co-author Michelle Tan, a researcher in the economics program at the Research School of Social Science, at Australian National University, as saying.

The results further showed that men and women tended to enter different occupations, even when they had similar personality traits and skills.

The findings also revealed that despite having the same occupations, similar men and women took home widely different pay packets.

The study used a sample of 5397 men and women drawn from the Household Income and Labour Dynamics in Australia survey, and sought to understand the extent to which personality determined occupation and whether this could explain the gender pay gap.

The authors say that women were found to report overall higher levels of extroversion, agreeableness, emotional stability, and conscientiousness than did men.

According to them, men reported higher levels of "openness to experience", and there was no difference in men's and women's sense of being able to control the events in their life.

The study also revealed that men's personality traits closely linked to some occupations: the more "agreeable" men rated themselves on a personality test, the less likely they were to be managers or business professionals; and the more "open to experience" men were, the more likely they were to be in business or education.

The extent to which women were "open to experience" was the main influence on the jobs they held.

Just like their male counterpart, the more agreeable women tended to be the less likely they were to be managers. However, unlike men, extroversion was associated with women entering managerial ranks.

While similar men and women often ended up in different occupations, this did not explain the gender pay gap.
