Abstract Military remnants in the Al-Muthanna desert are one of the most important risks facing the local population in the desert, due to its presence in large quantities and in large areas and in many types. Climate factors interacted integrated with each other, which led to the burial of many of these wastes. Sometimes wind erosion shows it, and there is a big role for dust storms and air precipitation to hide the war remnants in Al-Muthanna desert, due to the nature of the dry climate in it, which helped in the disintegration of its soil, which makes up most of the surface of the study area. It was also found that there is a large role of rain in burying many wastes, led to its concealment and the difficulty of seeing it with the naked eye, which required the use of explosive detection devices or dogs trained in that to investigate it. As for the casualties caused by the remnants of war, it has been continuous throughout the years (2004-2020), which claimed the lives of many local residents in the Desert, led by the year 2013, when the number of victims was. When studying the distribution of these remnants in the Desert region, it appeared that there are many areas in which war remnants are scattered in large areas, all of which are explosive and dangerous, such as mines, cluster bombs of different types, mortars and artillery. The Busayeh desert took the largest share of the area and the largest amount of war remnants. The research found that there are areas in which there are war remnants that are not registered with the Civil Defense Department in Al-Muthanna Governorate, such as Al-Juyou, Faydat Al-Faris, and Kilo.

Resistance to wind erosion enhancement of existing concrete is a new technology to reinforced concrete surface wind erosion, different from the previous wear-resistant research ideas adjustment made of concrete mix, and thick surface wear additional layers, aims to enhance the resistance of concrete surface wind erosion capacity. With fuzzy clustering analysis method, the author analyzes four different types of existing concrete interface reinforcement materials and Come to different effect. Cluster analysis showed that the composite emulsion concrete surface treatment materials can penetrate through the surface penetration means and react with concrete to form a dense network structure, can achieve the purpose of anti-erosion, the best overall performance.

There are certain remarks in Culture and Value in which Wittgenstein writes about Jews and about what he describes as their ‘Jewish mind’. In these remarks he appears to be trying to make a distinction between two different spiritual forces which operate in Western culture and which give rise to two different types of artists and works of art. On one side of the divide are Jews and works of art imbued with Jewish spirit. On the other side are men of culture and works of art which exhibit a non-Jewish spirit. Among the various remarks made in this context, he offers the following thoughts about the spiritual nature of Jews, their mentality, character and artistic achievements:‘You get tragedy when a tree, instead of bending, breaks. Tragedy is something un-Jewish’ (1). Following Renan he writes: ‘The Semitic races have an unpoetic mentality, which heads straight for what is concrete’ (6). This, he explains, is because Jews are attracted by ‘pure intellectualism’. ‘I think it would be possible now to have a form of theatre played in masks. The characters would simply be stylized human types.’ (In his opinion this suits Karl Kraus's plays and their abstract nature.) ‘Masked theatre is anyway the expression of an intellectualistic character. And for the same reason perhaps it is a theatrical form that will attract only Jews’ (12). ‘The Jew is a desert region, but underneath its thin layer of rock lies the molten lava of spirit and intellect’ (13). ‘It is typical for a Jewish mind to understand somebody else's work better than that person understands it himself.’ But intellect, it seems, is not a mental attribute providing for genius and true creative powers. ‘Amongst Jews “genius” is found only in the holy man. Even the greatest of Jewish thinkers is no more than talented. (Myself, for instance.) … It might be said (rightly or wrongly) that the Jewish mind does not have the power to produce even the tiniest flower or blade of grass; its way is rather to make a drawing of the flower or blade of grass which has grown in the soil of another's mind and to put it into a comprehensive picture. We aren't pointing to a fault when we say this and everything is all right as long as what is being done is quite clear. It is only when the nature of a Jewish work is confused with that of a non-Jewish work that there is any danger, especially when the author of the Jewish work falls into the confusion himself, as he so easily may. (Doesn't he look as proud as though he had produced the milk himself?)’ (18–19).

The Laplace transform of the extinction time is determined for a general birth and death process with arbitrary catastrophe rate and catastrophe size distribution. It is assumed only that the birth rates satisfyλ0= 0,λj> 0 for eachj> 0, and. Necessary and sufficient conditions for certain extinction of the population are derived. The results are applied to the linear birth and death process (λj=jλ, µj=jμ) with catastrophes of several different types.

Abstract We argue that Tomasello's account overlooks important psychological distinctions between how humans judge different types of moral obligations, such as prescriptive obligations (i.e., what one should do) and proscriptive obligations (i.e., what one should not do). Specifically, evaluating these different types of obligations rests on different psychological inputs and has distinct downstream consequences for judgments of moral character.

Previous freeze fracture results on the intact giant, amoeba Chaos carolinensis indicated the presence of a fibrillar arrangement of filaments within the cytoplasm. A complete interpretation of the three dimensional ultrastructure of these structures, and their possible role in amoeboid movement was not possible, since comparable results could not be obtained with conventional fixation of intact amoebae. Progress in interpreting the freeze fracture images of amoebae required a more thorough understanding of the different types of filaments present in amoebae, and of the ways in which they could be organized while remaining functional.The recent development of a calcium sensitive, demembranated, amoeboid model of Chaos carolinensis has made it possible to achieve a better understanding of such functional arrangements of amoeboid filaments. In these models the motility of demembranated cytoplasm can be controlled in vitro, and the chemical conditions necessary for contractility, and cytoplasmic streaming can be investigated. It is clear from these studies that “fibrils” exist in amoeboid models, and that they are capable of contracting along their length under conditions similar to those which cause contraction in vertebrate muscles.

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

In polyethylene single crystals pairs of black and white lines spaced 700-3,000Å apart, parallel to the [100] and [010] directions, have been identified as microsector boundaries. A microsector is formed when the plane of chain folding changes over a small distance within a polymer crystal. In order for the different types of folds to accommodate at the boundary between the 2 fold domains, a staggering along the chain direction and a rotation of the chains in the plane of the boundary occurs. The black-white contrast from a microsector boundary can be explained in terms of these chain rotations. We demonstrate that microsectors can terminate within the crystal and interpret the observed terminal strain contrast in terms of a screw dislocation dipole model.

Fibers composed of different types of collagen cannot be differentiated by conventional electron microscopic stains. We are developing staining procedures aimed at identifying collagen fibers of different types.Pt(Gly-L-Met)Cl binds specifically to sulfur-containing amino acids. Different collagens have methionine (met) residues at somewhat different positions. A good correspondence has been reported between known met positions and Pt(GLM) bands in rat Type I SLS (collagen aggregates in which molecules lie adjacent to each other in exact register). We have confirmed this relationship in Type III collagen SLS (Fig. 1).
