The writer commences her article by enunciating the doctrine that the normal human being is asymmetrical. “In 1903,” she says, “I expressed the opinion that the normal man is asymmetrical. The principle of the bilateral symmetry of the organism, established until recently in biological sciences, is replaced to-day by the idea of asymmetry, which, far from being an abnormal or pathological phenomenon, is, on the contrary, the expression of the natural state. One of the halves of the body is more developed than the other from an anatomical and physiological point of view. In the case of the right-handed man, it is the right side which is favoured; in the case of the left-handed man, it is the left. Now, each half of the body being dependent on the hemisphere of the opposite side, one sees that in the case of the right-handed man it is the left brain which is most developed, whilst in the case of the left-handed man a greater development of the right brain is assumed.” This thesis is supported by references to the works of many observers.

Structure Of Matter

The unity of the structure of matter fields with flavor symmetry laws involves that the left-handed neutrino in the field of emission can be converted into a right-handed one and vice versa. These transitions together with classical solutions of the Dirac equation testify in favor of the unidenticality of masses, energies, and momenta of neutrinos of the different components. If we recognize such a difference in masses, energies, and momenta, accepting its ideas about that the left-handed neutrino and the right-handed antineutrino refer to long-lived leptons, and the right-handed neutrino and the left-handed antineutrino are short-lived fermions, we would follow the mathematical logic of the Dirac equation in the presence of the flavor symmetrical mass, energy, and momentum matrices. From their point of view, nature itself separates Minkowski space into left and right spaces concerning a certain middle dynamical line. Thereby, it characterizes any Dirac particle both by left and by right space–time coordinates. It is not excluded therefore that whatever the main purposes each of earlier experiments about sterile neutrinos, namely, about right-handed short-lived neutrinos may serve as the source of facts confirming the existence of a mirror Minkowski space–time.

Axial Twist

The contralateral organization of the forebrain and the crossing of the optic nerves in the optic chiasm represent a long-standing conundrum. According to the Axial Twist Hypothesis (ATH) the rostral head and the rest of the body are twisted with respect to each other to form a left-handed half turn. This twist is the result, mainly, of asymmetric, twisted growth in the early embryo. Evolutionary selection tends to restore bilateral symmetry. Since selective pressure will decrease as the organism approaches symmetry, we expected a small control error in the form of a small, residual right-handed twist. We found that the mouth-eyes-nose (rostral head) region shows a left-offset with respect to the ears (posterior head) by up to 0.8° (P<0.01, Bonferroni-corrected). Moreover, this systematic aurofacial asymmetry was larger in young children (on average up to 3°) and reduced with age. Finally, we predicted and found a right-sided bias for hugging (78%) and a left-sided bias for kissing (69%). Thus, all predictions were confirmed by the data. These results are all in support of the ATH, whereas the pattern of results is not explained by existing alternative theories. As of the present results, the ATH is the first theory for the contralateral forebrain and the optic chiasm whose predictions have been tested empirically. We conclude that humans (and all other vertebrates) are fundamentally asymmetric, both in their anatomy and their behavior. This supports the thesis that the approximate bilateral symmetry of vertebrates is a secondary feature, despite their being bilaterians.

Shed Light

This chapter aims to shed light on the relationship between the development of laterality and the learning of mathematics in early childhood education using the ABN method. Thus, the authors present an experience developed with 24 children of 4 and 5 years old from several sessions of physical education where laterality and mathematics were worked on in the framework of a project developed in the classroom. The neuropsychological laterality test and a psychomotor table with values referred exclusively to manual and foot laterality, and indicators referred to the ABN method were used as evaluation instruments. The results obtained indicate that students with homogeneous right- or left-handed laterality obtain better results, as well as those with crossed laterality, since they have defined their manual and foot dominance. However, students with undefined laterality obtain worse results, even showing a lateral tendency towards the use of the right side of the body.

In the present work, the charged dark matters of B1, B2 and B3 bastons are explained as the right-handed partners of the left-handed neutrinos. And the rest masses of the elementary particles depend on their charge configurations. The left-handed neutrinos have only the lepton charges (LC) and the right-handed dark matters have only the electric charges (EC). This explains the fact that the rest masses of the left-handed neutrinos are so small, and the rest masses of the right-handed dark matters are relatively very large. The proposed rest mass (26.12 eV/c2) of the B1 dark matter is indirectly confirmed from the supernova 1987A data. The missing neutrinos are newly explained by using the dark matters and lepton charge force. The neutrino excess anomaly of the MinibooNE data is explained by the B1 dark matter scattering within the Cherenkov detectors. The quark mixing and neutrino mixing are not required in the present model. It is shown that our matter universe and its partner antimatter universe can be created from the big bang in the point of view of time -, charge -, space -, and quantum state &ndash; symmetric universe evolution.

The Difference

The effect of a single dose of 1 ml. 1:1000 adrenaline hydrochloride on the peripheral blood picture of fourteen normal human subjects was studied and an erythrocytosis and leucocytosis was seen in all the subjects. The magnitude of the variations observed have been recorded. No increase in the percentage of reticulocytes or a left shift in the granulocytes was noted. As the size of the post-adrenaline erythrocytosis and leucocytosis did not diminish in four splenectomized subjects, it is suggested that splenic contraction is not the causal factor of these phenomena in man. It seems that the post-adrenaline erythrocytosis in man is due to haemoconcentration, the granulocytosis to a mobilization of cells from the bone marrow and the lymphocytosis to a mobilization of cells from the lymph nodes and other lymphoid tissues in the body. The variations in the salivary leucocytes after adrenaline show that, when the effect of the drug begins to wear off and the blood leucocyte level begins to fall, leucocytes are eliminated in the saliva. When repeated injections of adrenaline were given to two normal subjects the magnitude of the lymphocytosis was no greater than after a single injection; on the other hand, a very large cumulative granulocytosis occurred, but no left shift was detected. It is suggested that the difference is probably due to the different rates of elimination and/or destruction of these cells in the body.

Perception of one's body is related not only to the physical appearance of the body, but also to the neural representation of the body. The brain contains many body maps that systematically differ between right- and left-handed people. In general, the cortical representations of the right arm and right hand tend to be of greater area in the left hemisphere than in the right hemisphere for right-handed people, whereas these cortical representations tend to be symmetrical across hemispheres for left-handers. We took advantage of these naturally occurring differences and examined perceived arm length in right- and left-handed people. When looking at each arm and hand individually, right-handed participants perceived their right arms and right hands to be longer than their left arms and left hands, whereas left-handed participants perceived both arms accurately. These experiments reveal a possible relationship between implicit body maps in the brain and conscious perception of the body.

Purpose. The work is devoted to functional, ceremonial and cultural-historical interpretation of the so-called kočidykcrutches often found at the sites belonging to various cultures of the steppe belt of Eurasia and popular during the Early Iron Age. The aim of our study is to describe different interpretations of this group of finds. We considered the accumulated historiographical experience and also tried to model experimentally the functional use of the artifacts analyzed. The scientific novelty of the study lies in the possibility of referring to these materials from the point of view of the hypothesis of multiculturalism. We discuss a number of variants how to reconstruct the functional use of this category of finds. In particular, the crutches considered could have been used as suspensions and as belt fasteners. Results. We noticed that regardless of the sex of the buried people, the location of the crutches in graves is the same, i. e. they are found on the right or left side, at least two on the femur or pelvic bones of the skeleton if the buried person had a belt and it was buttoned, and on the chest, knees or feet, if the belt was unbuttoned and was lying along the body. The crutches can either be a part of the complex, or the only element of the waist fittings that indirectly points to a certain self–sufficiency of crutches as a part of the burial shroud. There are controversial interpretations of the ceremonial meaning of the artifacts. Based on the hypothesis of multiculturalism of the population of the Upper Ob River region during the Early Iron Age, we provide some new cultural and historical interpretations of the crutches. A variety of types of crutches confirms the assumption that within the existence of the subject complex of clothing worn by the population of the Upper Ob River region in the second half of the I Millennium BC, there were clear signs of innovations. Conclusion. Studying the range of issues associated with the interpretation of crutches remains a relevant and promising task in archaeological research. Further accumulation of material and its understanding in a broader rather than narrow territorial context might allow us to identify the centers of distribution of certain types of crutches and the processes of their trans cultural incorporation into the traditional use by the population of the Upper Ob River region in the Early Iron Age.

The principles which the study of the Nerves of Sensation and of Voluntary Motion within the Orbit is thought to illustrate, are:—1. The peculiarity of the muscles of the Eyeball, that they receive few or no sensitive filaments, such as supply all other muscles of the body,—coupled with the peculiarity of their office, that they are designed, in the natural state, to be regulated, not by sensations excited in themselves by their action, but by sensations excited thereby in the Retina,—suggests an important reflection on the use of sensitive nerves and of sensations in guiding and regulating all voluntary and instinctive muscular motion; the sensations which result from the commencing action in every case fixing the effort of the will on the right muscles, and regulating the extent to which the contractions shall be carried; while experience in some cases, and instinct in others, teaches what motor nerves must act, in order to excite the commencement of these sensations.

For normal life, many different substances are needed, among which vitamins play an important role. Everyone knows that the word "vitamin" comes from the Latin "vita" - life. This name is not accidental at all [1]. Vitamins are low molecular weight organic compounds, very small amounts of which are required for the implementation of various metabolic processes in the body. Most vitamins are indispensable because are not synthesized in the human body. In their natural state, they can be found in very small quantities in all foods of organic origin [1,2]. Insufficient intake of vitamins from food is a global problem, and not seasonal, as it is mistakenly believed. For a number of reasons, a modern person cannot get them in the right amount with food. Inadequate nutrition, physical inactivity lead to metabolic disorders in the body and increase the risk of developing serious diseases [3,4,5,6]. One of the main problems faced by drug manufacturers is sometimes a short shelf life. In order to preserve the pharmacological properties of drugs, they add preservatives to them or place them in a vacuum package. To date, the most effective way to solve this problem is to use a modified atmosphere with nitrogen. The stability of solutions of easily oxidizable substances increases significantly if they are filled in an inert gas environment, for example, carbon dioxide, nitrogen or argon. This filling allows you to remove oxygen, this oxidizing agent that destroys unstable substances. The following factors influence the reduction of shelf life: oxidative processes, development of molds, reproduction of microorganisms. All oxidative processes in the packaging of a medicinal product occur under the influence of oxygen. As a result of this reaction, medications deteriorate. With the help of a pure nitrogen environment, it is possible to reduce the O2 content to a minimum level [7].

Accreditation Criteria

In our society, everybody seems concerned by sustainable development, however, when you discuss with European students, you realize that in many institutions, there is not much done and that for the time being it is always the same European universities that behave as "good students" and answer surveys and enquiries; it is necessary to find a way to make things evolve everywhere! Accreditation agencies are one of the solutions to improve the involvement of all the HEIs. The Commission des Titres d'Ingénieurs (CTI) is in France the body in charge of authorizing engineering universities the right to deliver the title of engineer. It states its own accreditation criteria that can evolve according to CTI's own ongoing reflexion or to the point of view of its stakeholders, as required by ENQA. Regarding social responsibility and SD CTI consulted for 3 years organisations directly concerned by SD and defined in February 2014 the item that must appear in HEI's self evaluation reports. Those points as well the demarche are presented in the paper
