Spring work had to be postponed again and again because of frost and bad weather. Now the head of the building yard, stefan sluzar, is hoping that the weather will cooperate to some extent this week and in the weeks to come. The paths and playgrounds throughout the city are to be repaired as quickly as possible.

Started the bauhof employees on the damm. There the winter, but also the braveheartbattle have left their mark. It is the roads and paths that have been particularly affected by the constant change from frost to thaw this year. "We are in the process of eliminating the most serious traffic hazards", says sluzar. This year, the condition of the roads connecting fridritt to fridritt and wermerichshausen to seubrigshausen is particularly bad. The old roads were not built for the loads of today’s traffic.But sluzar woman: "no one can pay for rubbing out". So they are being repaired.
A construction yard team is currently taking care of the gravel paths in the entire city area. There are several in the city center alone. The footpaths along the flood embankment require special attention. Because it is not only a matter of providing walkers with a proper recreational area, but also of the best possible maintenance of the dam as a protective facility.

In winter, the dense vegetation had to be removed so that roots could not damage the dam structure. Now the paths are being pushed off in such a way that no backwater forms there and runs off during rainfall. After that, a dark gravel layer is applied. On the music school path, the holes in the path were already patched before easter. And this is how it will continue over the next few weeks – from district to district."Working through one part of the site at a time", sluzar explains. In the building yard, there is a precise plan of where and in what order which upcoming work is to be tackled. According to stefan sluzar, this rule has been preserved. It’s a round trip similar to winter road maintenance, he explains. "The organization is not easy, but sluzar has fun with it. "This is a challenge for me", says the head of the public works department and mentions that the city, with an area of 95 square kilometers, is lower franconia’s largest and bavaria’s second-largest flat municipality. There is no end to the work.

The playgrounds also need to be systematically cleaned up in the next few days and weeks. There are 29 of them in the whole city. The main annual inspection is currently underway. "Every screw is really looked at", says sluzar.

But also in the sky the playgrounds are looked at more closely. It must be ensured that no rotten ashes fall from the trees and injure children. But the children’s playgrounds keep the construction team busy all year round. In addition to the rough inspection in spring, there is another basic inspection every quarter. And every week a look is taken at the facilities to make sure that there are no broken pieces or garbage lying around and that more serious damage is repaired immediately.

And now of course there is the maintenance of the grounds to be done – when spring comes. "There is no more snow now…" Word sluzar. He really can’t use him anymore now.

Salmonella found in free-range eggs during inspections. According to several media reports, the eggs were sold in branches of aldi nord, penny and REWE. According to the augsburger allgemeine, stores in brandenburg, saxony-anhalt, saxony, thuringia – and bavaria are affected. It is not yet clear to which stores the contaminated eggs were delivered.

Affected eggs are easy to identify

Eggs that may have been contaminated with salmonella are easy to identify: they are printed with the code 1-DE-1504401 and have a best-before date between the 20th and 20th day of the month.09.2017 and the 12.10.2017. Those who bought affected eggs can bring them back to the retailer.

Salmonella illness does not become apparent until a few days after ingestion of the bacteria. Symptoms include diarrhea, abdominal pain, vomiting and low-grade fever. As a rule, the symptoms in healthy adults subside on their own after a few days. Infants, toddlers, seniors and people with weakened immune systems may develop a more severe course of the disease. It is urgently recommended that they seek medical help. Adults with worsening disease are also advised to consult a doctor.

Untersteinach/kulmbach – the participants of the end-of-season party of the private bowling association (pkv) kulmbach and surroundings, which took place for the fifth time this year in the hall of the kulmbacher kleinkunst-brettla (KKB) in untersteinach, experienced a very entertaining evening with some acclaimed spontaneous falls. As always, the most successful individual bowlers and the best teams of the three groups were awarded prizes.
The outstanding data and facts of the past season were again summarized by sporting director werner spindler in an impressive set of figures. Accordingly, the 13 clubs of the pkv fielded a total of 175 active players in 28 teams. 350 times they reached or exceeded the 200-wood mark, ten of them even over 240 woods. The highest team score on a match day was by no means achieved by the old and new champion LK limmersdorf, but by the runner-up KC herlas with 1079 wood, followed by schwarzer panther untersteinach with 1070 wood and kegelfreunde melkendorf with 1067 wood. In one match the opponents tied, four times the happy winner left the track with a single wood advantage.
According to the sports director, the question of promotion and relegation remains open. A decision can only be made once it has been determined how many teams will be competing in the next season (entries must be received by 30 september). June at W. Spindler). The current rule that the two best teams from the lower groups are automatically promoted and the two teams at the bottom of the table from the upper groups are automatically relegated no longer works if the number of teams continues to fall. For a sensible grouping, a different rule may be necessary.
Pkv-chairman michael pohlmann had again some thoughts about bowling, which should not be taken too seriously, and recited them with a guitar at the beginning of the match.

Fight against local celebrities?
In his witty greeting, kulmbach mayor frank wilzok suggested a celebrity match between a pkv selection and a team of local politicians before the start of the next pkv season. He also promised that he would try to get the city of kulmbach to provide a new challenge cup for the best pkv team, because the previous cup had passed into the possession of the lindenkegler from limmersdorf after winning it three times.
Strong applause also for deputy district administrator jorg kunstmann, who presented the district challenge cup to runner-up KC herlas and praised all the pkv clubs for their efforts great performances and changed the three letters KKB to "nobody bowls better".
The challenge cup of the city of burgkunstadt was presented by horst bormann of the bandlschiebern to gut holz kulmbach. For the champion of group 2 there was the cup of the wahlergemeinschaft kulmbach, which ralf hartnack presented to the bowling friends 66. Bandlschieber burgkunstadt II received the giant inge aures trophy from michael pohlmann as group 3 champion.
The KKB band played a major role in the success of the evening, providing the best musical atmosphere from the very beginning. Bernd wunder

Bavarian SPD wants to extend truck tolls to all federal and state roads. This is the demand of the infrastructure motion to be passed at the SPD party conference in amberg on saturday. SPD state leader florian pronold said in munich on tuesday that it was mainly trucks that were breaking the roads. The extension of the truck toll was two to three billion euros more money in the coffers spool. The car toll demanded by the CSU can be dispensed with.
Social democrats also push for shifting freight traffic to the railways. The proposal also stipulates that in the future, transport projects will be implemented according to a clear list of priorities. In addition, the rehabilitation of existing infrastructure was to be given priority over new construction as a rule. The SPD wants to launch a special program worth 200 million euros to make bavarian train stations accessible to the handicapped.
Another topic at the state party conference will be the controversial sale of the GBW housing company. SPD top candidate christian ude wants to speak on this issue. SPD party vice-president manuela schwesig also announced her support for the care allowance.
At the infrastructure party conference, the SPD leadership actually wanted to win over the base for the expansion of the munich airport. After the burgers' vote against the third runway, however, this conflict issue has been postponed for "the next ten years" done, pronold said.

At first glance, the small fish seem a little disoriented. The cichlids swim back and forth in their tank, and every now and then an animal leaves the group but soon returns.

Alex jordan sees more in the movements of the fish than just simple swimming around – the biologist conducts research at the university of konstanz on how animals behave in black pools. Specifically, they look at how the group influences the behavior of the individual and vice versa.

"Thanks to new technology, we are also able to explore collective behavior in a new way," says jordan. In the past, the focus was mainly on individuals – simply because it was not possible or very time-consuming to observe an entire group at the same time. "Before, the rule was: one diver, one fish. Now we are using technical possibilities, for example, to study the movement of the animals in the swarm, for example, by using several cameras."

In 2016, a top research center for the study of swarm and collective behavior was established at constance university, where behavioral biologists and experts from the fields of computer graphics and data analysis are working together. Based on the analysis and visualization of movement data of large animal swarms, the scientists want to create new approaches for the study of swarm behavior and group dynamics in animal collectives. In one experiment, for example, the scientists led by jordan examined how information is passed on within the group.

In essence, it works like this: one of the cichlids is taught, with the help of conditioning, to distinguish between yellow and blue light – if one color glows, there is food, if the other glows, there is no food. If the fish returns to the group, the other animals can learn from it by gradually copying its behavior. So that the individual fish can be recognized, they wear a small plate with a kind of barcode on their heads.

The researchers observed an interesting detail: when the fish dances out of line at the beginning of the experiment and swims towards the yellow light towards the other group members, because only it knows that there is food there, the other animals in the shoal are more likely to notice this if it is a subordinate fish. "The dominant animal swims back and forth a lot anyway," says jordan. Therefore, the new behavior is not even noticed by the other group members as unusual at first.

But what do you do with such findings?? An example is given by jens krause from the leibniz institute of aquatic ocology and inland fisheries (IGB) in berlin. Together with his team, the scientist derives models for the dynamics of crowds from the swarm behavior of fish, for example. "For example, we looked at how animals move in groups."The researchers found that a few animals with a directional preference are sufficient to control a group. The scientists tested this on groups of up to 200 people. "Here, too, rough groups can be steered if a few know where to go."

But swarm research also provides valuable information on decision-making processes: "we looked at how doctors diagnose breast and skin cancer," says krause. In a second step, the researchers investigated how this recognition can be improved using methods of collective intelligence. The result: when you combine the opinions of at least three medical professionals, the result can be better than the best single doctor in the group. In humans, too, decisions made collectively often turn out better than the choices made by individual fighters.

For many experts, the methane deposits discovered nine years ago in the atmosphere of the inhospitable planet were considered an indication of extraterrestrial life.

The international team of scientists had irradiated parts of a meteorite under mars conditions with ultraviolet light, whereupon the gas molecules formed. "Methane is formed from countless small micro-meteorites and interplanetary dust particles that land on the surface of mars from space," explained atmospheric chemist frank keppler. "The energy is provided by the extremely strong ultraviolet radiation."The results have been published in the scientific journal "nature".

Since scientists found coarser amounts of methane on mars, there is much speculation about the source. One hypothesis is that microorganisms form the gas and that this could be an indication of life on the red planet. Geological methane sources such as volcanoes are also being discussed. According to projections, mars produces 200 to 300 tons of methane per year, keppler said.

Without a mars expedition, but with the help of the meteorite murchison, the researchers from mainz and the universities of utrecht and edinburgh found that uv light decomposes the carbon compounds in the meteorite rock. "Unlike earth, mars lacks a protective ozone layer that could absorb most of the uv radiation from space," keppler explained. The mars atmosphere is very dark, so that a much smaller fraction of the meteorite material burns up than on earth.

The meteorite murchison contains several percent carbon and has a similar chemical composition as the coarse part of the meteorite rock that lands on mars, explained the cosmochemist ulrich ott from mainz, germany. The 4.6-billion-year-old meteorite hit the australian town of murchison in 1969. When samples were exposed to UV radiation, considerable amounts of methane escaped almost immediately.

The results may disappoint all those who firmly believe in the biological origin of methane, the max planck institute announced. But the researchers could not rule out the hypothesis of martian microbes. It is quite possible that other processes contribute to methane production, said keppler.
