Extreme conditions in wetlands may be the niche of development of colonies of bacteria. In this chapter, the authors study the gnotobiology of moderate bacteria within the saline wetland of Sidi El Hani. In terms of geology, the coring within the sedimentary filling of the wetland shows color variation from white, grey, black to red related to the variability of bacteria species. On the other hand, in terms of microbiological investigations, isolates of bacteria show a variability from Gram+ to Gram-, from oxidase+ to oxidase-, from catalase+ to catalase-. This geobiological variability is related to radical change in climatic conditions. In doing so, the wetland of Sidi El Hani may record the climatic variability during the Late Holocene. On the other hand, it may be considered as terrestrial analogue with a development of extremophiles.

The harsh climatic conditions of the coast of the Tatar Strait make explainable the large number of patients with frostbite who passed under our supervision during the winter of 1935-36 and amounted to 2.8% (26 people) of the total contingent of inpatients. The variety of recommended methods for treating frostbite, on the one hand, and the relatively long recovery period for all of them, on the other hand, made us take a critical approach to the proposed methods of treatment. All currently existing methods are reduced to the treatment of frostbite areas with bandages; and on the locus morbi apply indifferent or slightly disinfecting ointments, or a similar property of a powder, or wipes moistened with slightly disinfecting solutions, for example, Sol. kalii hyperm. 1: 1000. The apparent similarity of the external manifestations of frostbite and burns inspired us with the idea of ​​conducting frostbite therapy in an "open way", which has long occupied a well-deserved place in the treatment of burns.

In certain accelerated flows the entrainment in the boundary layer, as normally defined, may be either zero or negative; on the other hand, there is no reason to suppose, on physical grounds, that the spread of mean or fluctuating vorticity should cease or become negative in such flows. This paradox is resolved in the present paper. It is also shown that in the equilibrium turbulent sink-flow boundary layer, where the entrainment as normally defined is zero, the reduced advection along streamlines in the outer part of the layer comes about mainly through increased dissipation: there is no reason to assume any radical change in the turbulence structure.

In Hungary the operating medium of game management and the guided hunting sector is undergoing such a radical change nowadays that on the one hand it considerably influences the profit-producing ability of the sector, and on the other hand it sets the actors of the industry new challenges and opportunities. If the Hungarian hunting industry, which has a traditional past, also wishes to preserve its position in this changed business medium, it is essential that the new situation be thoroughly assessed, and the value-oriented marketing attitude be adapted. The phenomena presented in this essay discuss the consequences and causes of the appearance of new service providers regarding the supply side, and the content changes of the consumer group and the modification of earlier consumption preferences and their causes on the demand side. The changing of the two media jointly generate the adaptation of the value-oriented service - marketing concepts, by using which the areas to be developed and deemed as the narrow cross-section of consumer decisions can be determined. After specifying the target group specific marketing properties of the aove-mentioned – prestige – service, such services of high utility content can already be established successfully that can be positioned as a proper alternative for the new consumer group of higher value expectation. On the other hand, the employment and profitability indexes related to this sector may considerably be improved.

It is just twenty years ago that I read a paper on the “Problem of Psychogenesis in Mental Disease” before this Society. William McDougall, whose recent death we all deplore, was in the chair. What I then said about psychogenesis could be safely repeated to-day, for it has left no visible traces, or other noticeable consequences, either in text-books or in clinics. Although I hate to repeat myself, it is almost impossible to say something wholly new and different about a subject which has not changed its face in the many years that have gone by. My experience, however, has increased and some of my views have matured, but I could not say that my standpoint has had to undergo any radical change. I am therefore in the somewhat uncomfortable situation of one who, on the one hand, believes that he has a well-founded conviction, but, on the other hand, is afraid to indulge in the habit of repeating old stories. Although psychogenesis has been discussed long ago, it is still a modern, even an ultra-modern, problem.

The comparison of modern climatic conditions and soil salinity in subboreal deserts of Middle Asia (Turanian plain) and Central Asia (Gobi deserts) shows that climate has an effect on salinity of hydromorphic soils. From the other hand, the distribution and degree of salinity of automorphic desert soils are predominantly governed by the distribution of salt-bearing rocks inherited from the previous geologic stages and are not related directly to the modern aridity. This fact allows us to state that the global warming will not promote salinization of automorphic soils of arid regions, except for the soils subjected to aeolian salinization. Climate aridification will provoke soil salinization in hydromorphic conditions.

In a multi-enterprise agriculture model, six different cropping systems have been evaluated at research farm of CSSRI Karnal for nutrient availability in surface soil. All the cropping systems left tremendous effect on soil quality. Among the different cropping systems, sorghum-berseem maintained lowest soil pH (8.14) followed by cowpea-cauliflower-potato cropping system (8.35). Sorghum-berseem cropping system was significantly build-up of soil fertility in terms of available nitrogen, (221.1kg/ha) and soil organic carbon (0.59%) as compared to other cropping systems. However, phosphorus (59.80 kg/ha) availability was higher in vegetable system followed by wheat-green gram cropping systems (48.85 kg/ha) than the other cropping systems. Vegetable system of multi-enterprise agriculture model showed more availability of Ca (3.20 me/L), Mg (2.63 me/L) and S (11.71 me/L) than other cropping systems. Higher amount of Fe (8.44 mg/kg) was observed in maize-wheat-green gram cropping system, whereas higher Mn (6.37 mg/kg) was noticed in sorghum-berseem fodder system than the other cropping system. Zn and Cu availability was relatively higher in vegetable system. Under prevailing climatic conditions of Karnal, sorghum-berseem fodder system was found to be the best with respect to soil quality and ready adaptability by the farmers as it was not much changed by climatic variability over the last 6 years. Vegetable system and fruits + vegetable were more or less similar in accelerating the availability of nutrients. Thus, leguminous crop (green gram) in any cropping system helped in improving the soil health, which is a good indicator of soil productivity.

Comparison of the chemical composition of domestic common hornbeam (Carpinus betulus L.) wood and exotic yakal (Shorea astylosa Foxw.) wood. The study was carried out to compare the chemical composition of domestic hornbeam wood with exotic yakal wood, which is an endemic species occurring in the Philippines. Species of similar structural structure occurring in different areas were studied. Extractives, cellulose (including α-cellulose), holocellulose (including hemicelluloses), lignin and ash contents were analyzed. The obtained results indicated lower content of cellulose, α-cellulose, lignin, extractives and ash in hornbeam wood as compared to yakal wood. On the other hand, a much higher amount of hemicelluloses (by 12 percentage points) was found in hornbeam wood. Probably, the main reason for the differences in the chemical composition of wood were different habitat and climatic conditions, in which the studied species were growing.

  The survival ability and development of the free living stages of Dictyocaulus. filaria larvae were studied to understand the epidemiology of this parasite in irrigation system . Galvanised iron boxes were planted and containated at subsequent times by faeces containing the larvae. Then faecal , soil and pasture samples were examined weekly, climatic conditions were recorded in  Baghdad area.  The results showed that the free living larvae survived and migrated from the faeces to the soil and pasture in the squares of the 2 nd group of boxes which has been contaminated in January for a longer period in comparison with other groups. The larvae survived until the 1 st week of April in their faecal , soil and pasture samples. On the other hand , no larvae could be recovered after one week of contamination in the fifth group of boxes which has been contaminated in July. In the other groups of boxes, the larvae survived for (98) days in the 1 st group , (49) days in the 3 rd group and for (21) days in the 4 th group, however, the number of larvae in the soil and pasture in all groups was lower than that in the faeces, and the presence of larvae in the soil was recovered for short time  The climatic condition during December , January , Febreuary and March had good influence on the survivability and moulting of the larvae in comparison with the adverse effect of other months . *Part of his M.Sc.

Granulometric Characteristics

The sedimentological and stratigraphic study of the two shelters: Gaudry and Lartet of the Montgaudier deposit made it possible to characterize the large sedimentary assemblages and to describe within each of the discontinuities revealed by the granulometric characteristics that have subdivided them into distinct layers. Moreover, the detailed sedimentological analyzes of these two shelters have led to the conclusion that the sediments are deposited under the cold climatic conditions alternated by the temperate episodes. On the other hand, the stratigraphic lithostratigraphic arguments allowed us to establish a stratigraphic relationship between the two shelters. From a chronological point of view, the deposits of the shelter Lartet appear to a Mousterian Charentian type contemporary to the old würm. As for the Gaudry shelter, layers 1 and 2 are contemporary with Magdalenian and layer 5 is attributed to the aurignacian. This is confirmed by an absolute date.

What is the role of conflict in bringing about radical change? Taking the case of the gig economy, we study the conditions of possibility for fairer alternative ways of organising to emerge, and the relative impeding forces. Currently, some commentators underscore the sense of freedom of working as a self-employed contractor; others focus on its negative and exploitative dimensions. Less attention has been given to the potential for the emergence of (radical) conflicts around the nature of gig work contracts that might be expected. We analyse this puzzle by appreciating how, on the one hand, neoliberal gig work mobilises positive fantasies of self-entrepreneurship, leading to reformist responses to contractual disputes; and, on the other hand, how the dark side of gig work can trigger radical conflict, which rejects the assumptions underpinning the “self-employed contractor” business model. The prospect of imaginative labour revolts is, we argue, buffered by neoliberal individualisation and hegemonic ideology – articulated in the phenomenon that we term “econormativity”. Yet, since its elements offer no resolution to structural grievances, conflict continues to simmer in the background. Thus, this work aims to improve from an organisation studies perspective our understanding of conflict and its role in unleashing radical alternatives.
