DPT and environmental tracers were combined to characterise alluvial aquifers. However, characterising groundwater resources in this remote part of Australia is challenging due to a lack of existing infrastructure and data. Here, direct push technology DPT was used to characterise shallow alluvial aquifers at two locations in the semiarid Flinders River catchment. DPT was used to evaluate the saturated thickness of the aquifer and estimate recharge rates by sampling for environmental tracers in groundwater major ions, 2H, 18O, 3H and 14C. The alluvium at Fifteen Mile Reserve and Glendalough Station consisted of a mixture of permeable coarse sandy and gravely sediments and less permeable clays and silts. The alluvium was relatively thin i.

Our blog of travels both near and far, in our wonderful country New Zealand and occasionally overseas. They took our money and we were joined up straight away — no questions asked! The Sixties Up Movement is a body of senior members of the community made up of those who are active, usually no longer in full time employment, who meet in local branches to find new friends and activities.
One of the Movement’s main objectives is to offer opportunities for members to maintain and expand their minds and bodies with social communication and educational and recreation activities. All aboard the bus As former Hutt Valley residents we can remember when this building used to house the National Film Unit. Our speakers for the morning were Katie and Delia, who have an impressive range of academic achievements between them.
They welcomed us to the theatre in the facility and presented a slide show of their respective areas of research. It focuses on geology, geophysics including seismology and volcanology, and nuclear and isotope science, and carbon dating. As well as undertaking basic research, and operating the national geological hazards monitoring network, GNS Science is employed, both in New Zealand and overseas, by various private groups notably energy companies , as well as central and local government agencies, to provide scientific advice and information.
The long drawn out process of Geological mapping was explained. With many field trips made to collect rock samples and take measurements, then back to the lab to plot and collate huge amounts of data, the geological map is slowly built up.
Ice core basics
Ice-sheet dynamics Sampling the surface of Taku Glacier in Alaska. There is increasingly dense firn between surface snow and blue glacier ice. An ice core is a vertical column through a glacier, sampling the layers that formed through an annual cycle of snowfall and melt. At Summit Camp in Greenland, the depth is 77 m and the ice is years old; at Dome C in Antarctica the depth is 95 m and the age years. The bubbles disappear and the ice becomes more transparent.
Ice is lost at the edges of the glacier to icebergs , or to summer melting, and the overall shape of the glacier does not change much with time.
The K/Ar Dating technique General assumptions for the Potassium-Argon dating system. Certain assumptions must be satisfied before the age of a rock or mineral can be calculated with the Potassium-Argon dating technique. These are: The material in question is a closed system.
Microvertebrate Fossils from the Late Cretaceous Not all fossils are big! Tiny bones, teeth, and other small animal fossils can provide rich and exciting information about biodiversity the variety of species living in a place in ancient ecosystems. FossiLab volunteers are helping Natural History Museum scientists by cleaning and sorting small fossils collected in North Dakota and Montana. Matthew Carrano and his colleagues travel regularly to several sites in Montana in search of fossil evidence of the small animals that lived alongside dinosaurs during the Late Cretaceous, 75 million years ago.
They fill buckets with loose clay matrix at sites where small fossils are abundant, and ship the buckets back to the museum. Hans-Dieter Sues similarly collect fossil-rich matrix in North Dakota and Montana at sites dating from just before and after the asteroid impact 66 million years ago that cause dinosaurs and many other Cretaceous organisms to go extinct. In our behind-the-scenes lab we use a machine constructed from a bicycle wheel and a motor to loosen and rinse away the clay, then, in FossiLab, we examine what’s left behind with microscopes in search of the many different kinds of tiny fossils.
The work is slow but the tiny fossils are beautiful and fun to find. A volunteer uses a brush to sort through washed sediment in search of small vertebrate fossils. Clockwise from Top Left: We soak the matrix in water and pour it into sieves. The sieves go into our fossil washing machine which slowly and repeatedly dunks them in buckets of water. The clay matrix dissolves and passes through the holes in the sieves, leaving the tiny fossils behind.

Signs and symptoms Main symptoms of malaria  The signs and symptoms of malaria typically begin 8—25 days following infection,  but may occur later in those who have taken antimalarial medications as prevention. Symptoms of falciparum malaria arise 9—30 days after infection. Possible causes include respiratory compensation of metabolic acidosis , noncardiogenic pulmonary oedema , concomitant pneumonia , and severe anaemia. It is associated with retinal whitening, which may be a useful clinical sign in distinguishing malaria from other causes of fever.
Plasmodium Malaria parasites belong to the genus Plasmodium phylum Apicomplexa.
Water distillers improve the taste of water from the tap by taking out contaminates. These countertop devices listed on eBay use electricity to distil a gallon of water in five hours, and many use charcoal filters to remove impurities, such as chlorine and suspended particles.
Soon after the elections, she was deployed to the new president’s personal office as a senior typist. Unsurprisingly, she was ambivalent about the job. One morning a fortnight after she’d started, she was walking down a corridor when several people burst through a doorway ahead. And suddenly, la Grange found herself face to face with the first black head of state in her country’s history; its first democratically elected president, and the man known in her family as “the terrorist”.
Tim Bauer La Grange is a tall stately woman, with a strong jaw, a lot of teeth when she smiles, and her hair braided around her head like Brunhilde. She worked for Mandela for 19 years, first on his general staff, then as his private secretary, then as his personal assistant until his death in Good Morning, Mr Mandela has nothing to do with leadership or statecraft or the nuances of realpolitik.
Instead, it describes what it was like to work, day after day, year after year, for a man who’d been imprisoned and degraded for 27 years but retained immense personal dignity and charisma; a man the wealthiest people on earth paid thousands of dollars just to sit beside at dinner, but who liked to take his own dry-cleaner to lunch; a man who redefined the concept and power of global celebrity, but who had never heard of McDonald’s.
One is through death, the other is love. Fire keeps me alive, and the guests entertained. If the mistress knew my real skill, well.

How do ice cores work? Current period is at right. From bottom to top: Milankovitch cycles connected to 18O. From top to bottom: Ice sheets have one particularly special property. They allow us to go back in time and to sample accumulation, air temperature and air chemistry from another time. Ice core records allow us to generate continuous reconstructions of past climate, going back at least , years. By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature.
Ice coring has been around since the s.

Water Filter About Water Distiller The quality of many types of coffees, teas, and powdered drinks begins with having great quality water. Water distillers improve the taste of water from the tap by taking out contaminates. These countertop devices listed on eBay use electricity to distil a gallon of water in five hours, and many use charcoal filters to remove impurities, such as chlorine and suspended particles.
Distilled water beats all forms of bottled and tap water simply because both types include bacteria and added minerals, even if the water was originally distilled. Many health advocates advise using home water distillers to remove up to 99 per cent of impurities, including inorganic molecules that change the taste of water or could adversely affect your health.
Since the water is not stored for long periods of time after the distillation process, bacteria has less time to recontaminate the container or grow to large amounts.

Groundwater Age-Dating for Water Resource Characterization Background The increasing national and international demand for water has led to increasing reliance on subsurface storage, both for naturally and artificially recharged water. This increased reliance on the groundwater in concert with the strict regulation on water quality has led to a need by water managers and regulators to understand: How much and on what time scales groundwater can be recharged and withdrawn in specific sub-basins, Groundwater flow fields at both recharge and basin scales, Water quality impacts of recharge water storage and recovery in a subsurface that is bio-geochemically active, How changes in management practices have and will affect water quality, and Future distributions of contaminants in the subsurface.

Resources Contact and General Information If you think you are experiencing symptoms related to exposure to blue-green algae e. If your pet displays symptoms such as seizures, vomiting, or diarrhea after contact with surface water, contact your veterinarian right away. If you are or your local community is interested in collecting samples for analysis, please contact the Wisconsin State Laboratory of Hygiene at The Wisconsin Department of Natural Resources is not currently conducting any routine monitoring for blue-green algae or blue-green algal toxins.
What are blue-green algae? Blue-green algae, also known as Cyanobacteria, are a group of photosynthetic bacteria that many people refer to as “pond scum. Blue-green algae generally grow in lakes, ponds, and slow-moving streams when the water is warm and enriched with nutrients like phosphorus or nitrogen. When environmental conditions are just right, blue-green algae can grow very quickly in number.

Share via Email Dating apps throw up particular problems when it comes to preferences and race. Loading up Grindr , the gay dating app that presents users with potential mates in close geographical proximity to them, the founder of a Los Angeles-based Asian television streaming service came across the profile of an elderly white man. He struck up a conversation, and received a three-word response: For black and ethnic minority singletons, dipping a toe into the water of dating apps can involve subjecting yourself to racist abuse and crass intolerance.
Seeing that all the time is grating; it affects your self-esteem. Where we once met people in dingy dancehalls and sticky-floored nightclubs, now millions of us look for partners on our phones. Four in 10 adults in the UK say they have used dating apps. Globally, Tinder and Grindr — the two highest-profile apps — have tens of millions of users.
