Abstract Considering the spread of the grey wolf (Canis lupus) in Europe over the past 30 years, Luxembourg took some measures to prepare for the return of this apex predator, including the establishment of a management plan that notably addresses the issue of wolf depredation on livestock. Here we present the results of genetic analyses of putative wolf saliva, hair and scat samples collected from or near prey carcasses between 2015 and 2020. In two cases, the wolf was confirmed via DNA analysis: in July 2017 near Garnich and in April 2020 near Niederanven, both assigned to category C1 (hard evidence). A third case was classified as C2 (confirmed observation) based on prey carcass characteristics, while genetic analysis yielded no result. These are the first confirmed records of wolves in Luxemburg since 1893. Moreover, the two C1-cases originated from the Alpine (Garnich) and Central European (Niederanven) populations. Given similar developments in the neighboring countries and regions, we conclude that the area including the Benelux countries as well as Rhineland-Palatinate, Saarland and Northern France may well become a melting pot for wolves of the two aforementioned populations in the coming years and decades.

Human Interference

For three centuries the primary aspiration of Western governments has been constant economic growth but with the Industrial Revolution this objective became troublesome. In the 20thcentury unprecedented levels of industrial production and social consumption caused palpable harm to humans and the environment. Hannah Arendt and John Kenneth Galbraith turned their pens to such concerns and Bill Mollison and David Holmgren advocated a permaculture approach to growth, one that strives to limit human interference in natural growth processes. Today’s precarious economic and ecological imbalances could be stabilized by a shift in applied growth paradigms, from capitalist to permaculturist.

The Paper work "Rocker Bogie mechanism Geo-survey Rover" deals with attempt of improving the rover from its previous designs. The Geo-survey rover has got to operate rough and harsh environments that it had been designed but several factors restrict its operational capabilities, therefore the focus of our research is to overcome restrictions or to decrease it to within an acceptable range for its smooth performance.. The rover has been completely made from PVC to increase its capability to withstand shocks, vibrations and mechanical failures caused by the tough environment where it's operated on. NASA made and developed this mechanism to use it on Space missions. Whereas these bogies are also preferred by many earthly situations where human interference is needs to be neglected. Usual mobility designs are complicate, using many wheels or legs. It is a multi-wheeled rover capable of travel through rough terrain using an effective higher degree of mobility. Drive train simplicity is the effective mechanical feature of the rocker bogie design, which is accomplished by using only six motors for mobility. All motors are located inside the body where thermal variation is kept to a minimum which increases reliability and efficiency. Six wheels are used because there are few obstacles on natural terrain that need both front wheels of the rover to climb simultaneously. A series of mobility experiments within the agriculture land, rough roads, inclined, stairs and obstacles surfaces concluded that rocker bogie can achieve a long way traverses on field.
