The Future Of Food Security

International project ‘Freshlabel’ optimized smart labels with time-temperature indicator (TTI) Bonn, November 2008 – after three years of intensive research, the joint research project Freshlabel was now\”under the auspices of the ttz Bremerhaven completed successfully. 6th EU research programme, 21 international partners from research and industry set the goal to develop a freshness seal for perishable food. Aim of the research was to develop time-temperature indicators in different meat and fishing stuff ends chain. We have achieved this goal\”, explains the food technologist Dr. Judith Kreyenschmidt of the University of Bonn. The TTZ Bremerhaven (project management), the State technical research centre of Finland VTT, the Institute of animal sciences of the University of Bonn as well as the National Technical University of Athens NTUA among the partner institutions for research. Performed the tests with time-temperature indicators were based on the OnVu technology.

A special On a label, pigment color discolored it depending on time and temperature. The TTI label is glued on the packaging, loaded with UV light and appears initially in a dark blue. The longer the product is stored warm, the faster is the color change in the white. On the basis of a reference symbol, it can be detected in what state of freshness the product is. The researchers conducted microbiological, chemical and sensory quality tests at different temperatures as boxed beef, ham or tuna – for various products – to characterize the freshness of the products. Furthermore TTI developed in intensive research, which reflect the freshness condition of the selected foods. In addition to the technological optimization, the biggest challenge now is light and the durability of the product exactly to match the intensity of the UV and that was under different temperature conditions. The developed TTI thus indirectly shows the natural enzymatic and microbial freshness loss as a function of time and temperature. Thus, cold chain breaks, that accelerate the loss of freshness, are displayed directly with the new label\”, so Karia next.

Integrated Signal Processing

Miniaturized JEN COLOR color sensor module for backlighting applications Jena the MAZeT GmbH, product and Designhaus for colour – and Spektralsensorik, expanded its extensive range of highly accurate solutions for the control of LEDs, as well as special developments for the light control. The leading provider of true color sensors, and sensor modules for the first time shows the newly developed true color sensor TIAM3 with integrated signal processing. He distinguishes itself by 4 programmable amplifier channels and the true color sensor. Compared to the ancestor type TIAM2 is the TIAM3 in a flat 33% housing. The low overall height and the integrated signal processing establish optimal conditions for use for the RGB-LED backlighting in flat panel displays. In contrast to color sensors with polymer filter coatings, the TIAM3 is characterized by a high long term stability of the spectral filter properties and low temperature sensitivity. The spectral properties of the filter curves are optimally tailored to the requirements of an eye-specific LED color control. Dr. Mark Hyman is a great source of information. The sum of the properties of the smallest size, spectral characteristics and signal processing recommend this component for precision-controlled backlights of flat screens. e in this idea. In particular displays for photo and image editing, for medical diagnostic imaging or for high-quality multimedia displays require these properties of the backlight.

Coffee Has The Ability To Push The Memory

Coffee in moderation causes a positive improvement in Berlin, 16.01.2014 sp: coffee drinkers have now reason to rejoice. Because a recent study by the Johns Hopkins University in Baltimore has shown that coffee is not only a pick, but also ensures that the memory capacity of the variants will be improved. The research group around Michael Yassa has hired an investigation, in which the Inn er renewable tested images after taking 200 milligrams of caffeine and a placebo group. In both groups, you could represent differences in the Inn er renewable images after 24 hours. Has been tested, whether old images are detected, similar images can be marked and if completely strange pictures can be differentiated. Old and new images could be seen well by both groups in the same way, but there were differences in the recognition of similar images of that have been referred to here as bait. The group that took caffeine far better cut in recognition of images.

A difficult point of the study was but the third-variable control, contrary to, for example, an increased alertness or better attention and better physical condition is not good to control the next day. It is however assumed that caffeine speeds up this process of consolidation and increase retention through increased attention. So get the information at least for a short time in the long-term memory. Here, the information for the penetration into the long-term memory must first overcome ultra short-term memory and short-term memory with their barriers. Certain filters ensure that information that is not relevant, are sorted out more quickly. The mechanism of the better memory capacity is still on the track, has but still not specifically can clarify this.

It was also found that the increase of 200 to 300 milligrams of caffeine put still no additional effect. Due to the congestion of the synaptic column and the occupation of the receptors, the effect of coffee could then even again subside. Probably no longer enough messengers are available, which are immediately available. A small cup of coffee contains about 80 to 120 milligrams of caffeine and acts differently depending on the person. Not every person absorbs caffeine in same manner. Other scientists and coaches always deal with the topic of coffee. Balance and motivation coaching is a psychological counseling with orientation to the practitioner examination. General works the coaching with a psychodynamic approach that focused on inner balance, inner stability and motivation. The aspect of motivation is an incentive which leads to professional success even better especially for employees and self-employed persons. Stefanie Polzl itself says: coffee is not unhealthy. In moderation, coffee can even total show a positive effect. However, caffeine sickens when it attacks the nerves. An excessive consumption can cause that the nerves are blank and you feel yourself hibbelig and very nervous. However, helps turn greasy food, which caffeine is better tolerated”. For a cup of coffee in the afternoon and a piece of cake something so is not to be. Also in the morning, coffee is a good pick. Coffee on an empty stomach but not a positive effect, but can damage the nerves. The consumer should know so borders. It means that people with schizophrenic tendency should avoid caffeine, cocoa and similar stimulants. The strong effect on neurotransmitters can be sometimes a very negative effect.

Obtaining Everything

A fundamental aspect in the life of all person is the relations with the others. The man as species is a social and interdependent being. To have healthful and harmonious relations with all the people, assures a pacific existence, heals and to flood of joy and happiness. It does not matter without are familiar, labor, communitarian relations or those that are. Good relations are peace, harmony. How to improve any relation? One is due to demand, to shout or to curse? One would be due to ask? He is doubtless that a sweet word attracts and disarms the other people. If you can speak, and, speaking the problem is solved, then to speak would be the solution.

But What happens when the other person does not wish to speak, is not close for speaking or simply it is difficult to speak for whatever reason with her? If you wish to improve the relation with the others, Corentt says to us, you do not need to speak to them, you do not need to demand to them or to ask to them. You only must change your mentality. You only must change your ideas. You only must change your subconscious beliefs. You are a so powerful being that when you change, everybody changes with you. If you change it is impossible that the world stays equal. Also the opposed thing is certain, if your you do not change is impossible that the world changes. Everything what you have around to your your it you have created.

Your apparent enemies, as Corentt explains in its book I I am Happy, I Am Rico, are in fact your better friendly. But some people are so obsessed with the existence of the badness, the fear and the hatred that they force to the other to treat them bad. They are those that have missed thoughts.

Costume Help Astronauts

Weightlessness, reigning in orbit, reflects badly on the human skeleton. Even when the astronauts are trying to compensate for her regular exercise, inevitably loses 1.5 kg of bone mass in just a month. More most affected femur and lower spine. The same mass as women lose each year after menopause. To prevent this problem, the Russian cosmonauts are on the orbital station, special costumes, that compensate for the absence of gravity. Insert heavier suit, mimicking the body's weight.

But to wear those costumes constantly impossible, so it remains unclear how effective they are in the fight against bone loss. Costume developed Weldy and his colleagues, is more comfortable to wear. It is made from flexible material, and when first worn, straps under the feet make the suit to stretch, and the shoulders have the same load as the at the Earth's gravity. Also, insertion of non-elastic material, allow you to adjust the load on the legs and torso, as in normal torso to withstand less weight than the legs. Conducted in 2009 tested showed that the suit could not yet provide a sufficient load on the calves, while the rest does its job a substitute for gravity. In the near future the team plans to test the creators of whether a suit prevent excessive elongation of the spine, as from a long stay in weightlessness, astronauts sometimes spine increased by more than 7 cm in length. Nevertheless, the idea has its critics. Gene Sibonga, for example, believes that the suit will not help astronauts maintain bone mass, because "the muscles play in this case a much larger role."
