boreholes

mastersara said: what’s a bore-hole? ._.

It’s a massive hole drilled into the ground

That’s how it works with water, it’s basically a MASSIVE well. After doing more research you couldn’t use the same borehole for water AND ground sourcing heat. BUT it would save money to hire the borehole digger for one day and get em to do two holes. That’s probably really naive but it’s a thought.

That’s a ground source heat loop. The reason granite is so good is because when you drill a big ol hole like that in the ground, if the rock or soil is too crumbly it runs the risk of collapsing on itself, so you need to insert a concrete sleeve to stop that from happening. With granite, it’s so hard it doesn’t need it. It also has a huge amount of solar energy stored in it.

It’s also easier to drill through because with crumbly or sticky soils you have to keep taking the drill up to clean it, but with granite you can just drill once and lift the chunk out in one lump.

Know : Rainwater Harvesting – Complete Info

The fresh water available in the earth is just 3%. Rain is one of the major sources of Freshwater, which we hardly consider preserving. Rainwater harvesting is a technique of collection and storage of rainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers (before it is lost as surface runoff). Even we can collect water from fog and dew! In this…

#769 - Fam. Naticidae - Moon Snail Attack

A clear sign that there are Naticids about. Moon Snails (also known as necklace shells) are large round predatory sea snails, common on sandy shorelines, that hunt other molluscs.

After ploughing up the sand to find a prey item, the moon snail envelops the victim prey and then bores a hole through the shell using its radula and acid secretion. The damage to this Pipi is typical - a wide conical “countersunk” borehole with chamfered edges, near the hinge. Once the shell is bored open, the proboscis is used to consume the flesh.

In the breeding season, some species lay a rather stiff egg mass which includes sand and mucus.Washed up on beaches they’re known as “sand collars” because of their resemblance to an old-fashioned removable shirt collar. On the other hand, the moon snails around here lay semi-circular, clear gelatinous sausages known in the parlance as “shark poo”

Smart Tool Helps East Africans Tap Into Safe Water

Shortages of clean water in East Africa and other developing regions can be devastating to food crops and livestock and deadly for inhabitants. However, smart water-management technology is helping to ensure safer supplies of the scarce resource. Element Blue sees success in the area of water management for Oxfam International with its custom SensorInsight Software

In drought-stricken East Africa, water is as precious as gold.

Water shortages during the dry season in the region often result in ruined harvests, livestock deaths and ultimately famine and disease.

That’s why Oxfam International, a global aid organization, set up outposts in parts of Kenya and Ethiopia to help mine the invaluable resource. By drilling additional boreholes, repairing existing ones and establishing new water points and tap stands, it has helped build a network of about 1,000 independent water points across the region.

Still, even with an improved operation in place, Oxfam understood that to ensure optimum delivery to the thousands of people in the region desperately in need of clean water, a smarter and more efficient system was required. That’s when it turned to IBM partner Element Blue to create a long-term water-management solution.

“Oxfam made great progress in drilling boreholes and creating schemes to ensure water was getting to the communities that needed it,” said Element Blue Chief Executive Officer Steven Gerhardt. “Once they had that system in place they needed a way to monitor and manage it for maximum efficiency.”

Real-Time Data

Element Blue had just the right tools to meet the challenge. The Houston-based software-solutions provider deployed its new SensorLight technology along with IBM’s WebSphere Application Server software and SoftLayer systems to give Oxfam a more sophisticated platform for ensuring the availability of safe and clean water.

The platform collects, aggregates and displays as many as 1,000 independent water points in Northern Kenya and Southern Ethiopia in a single dashboard. That gives Oxfam a 360-degree view of the region’s water conditions and allows local managers to monitor each water source for supply, demand and overall functionality.

Element Blue’s SensorInsight dashboard also analyzes near-real-time, real-time and historical data patterns for insight into trends and consumption levels. Through the use of preemptive alerts, Oxfam can also proactively manage and identify technical malfunctions, helping to avoid or minimize water shortages.

A Reliable Network of Clean, Safe Water

“SensorInsight is very exciting because of its ability to pull together so many forms of data, put it into formats that allow managers to monitor KPI’s [key performance indicators], and the shortened response times the real-time alerts provide,” said Element Blue Chief Technology Officer Joey Bernal.

Since its launch earlier in 2015, Element Blue’s water-management system has lowered field operating costs by 15 percent, reduced field managers’ travel costs by 50 percent and sped up the identification of water stress conditions or equipment malfunctions.

Through Oxfam’s efforts and the implementation of the smart water-management solution, East Africans now are able to tap into a more reliable network of clean and safe water. That’s an impact more valuable than gold.

Drug addict with history of suicide threats found dead in a borehole in Murang’a

Thursday, May 21, 2015 – A 23 year old drug addict who went missing last week from their home in Kangangu village in Murang’a County committed suicide on Tuesday evening by jumping into a borehole. Joseph Maina had a history of suicide threats with the latest one being on May 15 when he even dug his grave. His parents say that he had attempted to take away his life severally but he was rescued each time. The last time he attempted suicide, he dug his grave and instructed people that he should be buried in there when he kills himself. Area Nyumba Kumi official, Henry Kihara, said that the body of Maina was found by a neighbour who had gone to fetch water in the borehole. The area Chief, Loise Wandia, called on parents to take keen interest on their children. The body was moved to Murang’a District Hospital mortuary.

One of my favourite cases back when I was a final year student 😁❤️…Dental FLUOROSIS is a developmental disturbance of the outer layer of the tooth, the dental enamel, caused by the consumption of excess fluoride during tooth development. In South Africa, fluorosis is commonly seen in areas and populations whose water supply is untreated and unmonitored such as farms, rivers or borehole water. The risk of fluoride overexposure occurs at any age but it is higher at younger ages. It can vary from tiny white streaks or specks in the enamel of the tooth in mild fluorosis to severe brown discoloration in its most severe form. The enamel may be pitted, rough and hard to clean. The spots and stains left by fluorosis are permanent and may darken over time but can successfully cosmetically be treated by a dental professional…Just a little bit of info for your morning😁 #DRSMILE #EDUCATION #DENTISTRY #BAHAI by drsmilelexleo http://ift.tt/1AepkrA

Simple, affordable, and sustainable borehole observatories for complex monitoring objectives

Seafloor drill rigs are remotely operated systems that provide a cost-effective means to recover sedimentary records of the upper sub-seafloor deposits. Recent increases in their payload included downhole logging tools or autoclave coring systems. Here we report on another milestone in using seafloor rigs: the development and installation of shallow borehole observatories.

Three different systems have been developed for the MARUM-MeBo (Meeresboden-Bohrgerät) seafloor drill, which is operated by MARUM, University of Bremen, Germany. A simple design, the MeBoPLUG, separates the inner borehole from the overlying ocean by using o-ring seals at the conical threads of the drill pipe. The systems are self-contained and include data loggers, batteries, thermistors and a differential pressure sensor. A second design, the so-called MeBoCORK (Circulation Obviation Retrofit Kit), is more sophisticated and also hosts an acoustic modem for data transfer and, if desired, fluid sampling capability using osmotic pumps. In these MeBoCORKs, two systems have to be distinguished: the CORK-A (A stands for autonomous) can be installed by the MeBo alone and monitors pressure and temperature inside and above the borehole (the latter for reference); the CORK-B (B stands for bottom) has a higher payload and can additionally be equipped with geochemical, biological or other physical components. Owing to its larger size, it is installed by a remotely operated underwater vehicle (ROV) and utilises a hot-stab connection in the upper portion of the drill string. Either design relies on a hot-stab connection from beneath in which coiled tubing with a conical drop weight is lowered to couple to the formation. These tubes are fluid-saturated and either serve to transmit pore pressure signals or collect porewater in the osmo-sampler. The third design, the MeBoPUPPI (Pop-Up Pore Pressure Instrument), is similar to the MeBoCORK-A and monitors pore pressure and temperature in a self-contained manner. Instead of transferring data on command using an acoustic modem, the MeBoPUPPI contains a pop-up telemetry with iridium link. After a predefined period, the data unit with satellite link is released, ascends to the sea surface, and remains there for up to 2 weeks while sending the long-term data sets to shore.

In summer 2012, two MeBoPLUGs, one MeBoCORK-A and one MeBoCORK-B were installed with MeBo on RV Sonne, Germany, in the Nankai Trough area, Japan. We have successfully downloaded data from the CORKs, attesting that coupling to the formation worked, and pressure records were elevated relative to the seafloor reference. In the near future, we will further deploy the first two MeBoPUPPIs. Recovery of all monitoring systems by a ROV is planned for 2016.

Louis sells USDMWK 431: Corruption judgment will be passed on Lungu by the Zambian people, not himself - Mulongoti

“And Mulongoti says its does not make sense for government to acquire a US $14 million loan to improve water and sanitation … I do not know whether you require dollars to be able to sink boreholes in Zambia. No matter how difficult the terrain is, we …” said Ivelisse to Kaylene on Monday, May 18, 2015.

“My dear Miss Kaylene,” said Ivelisse, “have you heard that SPPR went up to 1159.42?”

“S&P International Preferred Stock Index.”

Kaylene replied that she had not.

“But it did,” said Ivelisse. “U.S. stocks surge, as S&P 500 reaches all-time closing high at 2,121.10 Investing.com - Investing.com – U.S. stocks moved broadly higher on Thursday amid a weaker dollar, as the S&P 500 Composite index reached an all-time closing high.

Kaylene, with her usual reserve, made no answer.

Friendship was a matter of life and death to the far Eastern POW.  As in Europe, a buddy would lift your mood when you were down and help you to pass the hours of boredom.  But in the Far East friendship offered practical benefits.  A good mate would bring you food when you were too sick to move, coax you to eat and make sure the medical orderly did not forget about you.  He would support you to the ‘borehole’ and knew which memories would lift your mood - whether that meant talking about your football team or your 'best girl’.  It helped to be part of a gang; a group of three was too small; five was the optimal number.

Steve Connor is the Science Editor of The Independent. He has a degree in
zoology from the University of Oxford and has a special interest in genetics
and medical science, human evolution and origins, climate change and the
environment.

The water was found pouring out of boreholes from a copper and zinc mine 2.4
kilometres deep beneath Ontario in Canada. Chemical analysis shows that the
water could support primitive microbial life forms if they were adapted to
living off the minerals and hydrogen seeping into the water from the
surrounding rock.

Tests by researchers have shown that the water is at least 1.5 billion years
old, but the surrounding geology suggests it could be much older, dating to
a time when all of life on Earth had not evolved much beyond primitive,
single celled microbes.

The scientists said they intend to analyse the water for signs of life,
which could help in the development of techniques for finding extra
terrestrial life forms living within underground pockets of water on either
Mars or Europa, one of the moons of Jupiter.

Our finding is of huge interest to researchers who want to understand how
microbes evolve in isolation, and is central to the whole question of the
origin of life, the sustainability of life and life in extreme environments
and on other planets, Professor Ballentine said.

The water has a similar composition of dissolved chemicals to much young
water found flowing from rock in a South African mine some 2.8km below
ground where microbes have been found to live, the scientists said.

Any life forms found in the water must be able to survive in total darkness
on chemical energy locked up in the ancient rock formation. Scientists have
begun tests to analyse the water for any microbes that have survived the
long isolation from the rest of the biosphere, said Greg Holland of
Lancaster University.

Our Canadian colleagues are trying to find out if the water contains life
right now. What we can be sure of is that we have identified a way in which
planets can create and preserve and environment friendly to microbial life
for billions of years, Dr Holland said.

This is regardless of how inhospitable the surface might be, opening up the
possibility of similar environments in the subsurface of Mars, he said.

Living organisms that can survive in extreme environments known as
extremophiles have been found in sediments retrieved from deep boreholes,
in boiling hot geysers, highly radioactive habitats, deep submarine trenches
and the dry, freezing deserts of Antarctica.
