WELLINGTON Mark Scheifele Jersey , June 16 (Xinhua) -- Pests like mice and wasps may one day be eradicated using a new technique which scientists have just proven in the laboratory on fruit flies, according to a study released on Friday.


Prof. Neil Gemmell, head of University of Otago's Department of Anatomy, said the "Trojan Female Technique" -- in which females pass on genes that make male offspring infertile -- offers pest-control advantages that are likely to help as New Zealand strives to reach the government's Predator Free 2050 goal.


In a research paper published by eLife, Gemmell and co-authors reported their success in making their theory about Trojan female fruit flies a reality in the lab.


"This is a world-first proof-of-concept and we need to test the general applicability of this approach more widely Josh Morrissey Jersey ," Gemmell said, adding that the technique uses naturally occurring mutations in mitochondrial DNA that affect male, but not female, fertility and fitness.


Mitochondria are considered the "power generators" of a cell and turn oxygen and nutrients into chemical energy which runs the cell's metabolic activities. "The essence of our idea is to use these mitochondrial mutations to produce continuous, self-sustaining biological control Joel Armia Jersey , he said.


"What we discovered some years back is that, as a by-product of the maternal inheritance of mitochondrial DNA, mutations that affect only males can occur quite commonly in populations, potentially contributing to fertility issues in some populations," he said.


"Our idea turns this problem around. If these mutations can affect population viability Connor Hellebuyck Jersey , we wondered if they might be turned into a tool that has the potential to control and even eradicate pests, Gemmell said.


Their study showed that population reduction, albeit at this stage quite modest, can be achieved in laboratory-raised fruit flies, and broadening this technique to introduce Trojan females into wasp and pasture weevil populations is under way.


While there are many tools to control pest populations Michael Hutchinson Jersey , this might be an important part of a growing arsenal, and around New Zealand there is a great deal of interest in this approach as a way to control rats, possums and stoats as part of the Predator Free 2050 goal, Gemmell said.


Pests are estimated to cost New Zealand about 3.3 billion NZ dollars (2.4 billion U.S. dollars) a year through lost productivity and cause profound damage to native fauna and flora. "The implications globally are even larger, particularly when insect-borne diseases Dustin Byfuglien Jersey , like malaria, are considered," he said.

Industrial radiography is being used in the construction and home improvement to ensure that everything remains practically safe and under control. Whether it is gas pipe leaking, or cess pool leaking or any construction underneath the flooring of your home or office Nikolaj Ehlers Jersey , advanced radiography techniques are being used. With these advanced techniques, it has become easy for the home improvement workers as well as construction engineers to know what all they are dealing with and how everything can be put in place and the order. There are several methodologies available which are put in use in the radiography for industrial purposes.
The radiography techniques used for industrial purposes are categorizes under digital imaging and these have turned out to be quite substantial. Home improvement and construction companies today are making use of advanced imaging techniques to bring in the difference to construction and improvement procedures.
Why go for the Hydrostatic Testing?
Hydro testing or hydrostatic testing is a sophisticated method which is put to use for detecting leakages in the pressurized pipes and containers. It works on the physical principle of fluid dynamics and pressure analysis. Dyed water is drained through the test pipes and vessels at a very high pressure. If there are any leaks in the pipelines they would be detected. Many of the manufacturers of pressurized pipes and containers also make use of this simple procedure to ensure that everything is in perfect state.
The very importance of Hydrostatic testing lies in:
• Detection of any types of leaks
• Any kind of breaks or holes in the pipes and containers
• The quality of pipe andor container
• Assessing the durability of containers, pipes, and vessels
Besides the hydrostatic testing, GPR is another test that can bring in valuable change.GPR of concrete is fast and reliable method of identifying the quality of concrete and to make the assessment of any leakage out there or not. GPR is also used for identifying the key areas of pipes that are known to be damaged.
All You Wanted to Know Welding procedure qualification
There is only one basic Welding procedure qualification and it is the updated documentation. The documentation should list all the variables which were put to use during the welding test along with inspection and the results. The variables used include size Bryan Little Jersey , type and classification of filler alloy, welding process used, size, type and classification of filler alloy, type and polarity of welding current Jacob Trouba Jersey , amps and volts recorded, welding position and many more.
