Climate change is a natural phenomenon but in present decades its variability of change mainly due to anthropogenic activities is alarming. Agriculture of Chhattisgarh state is mainly dependant on monsoon rain and its distribution. Considering this fact, the present study  has been tried to analyze the most important climatic variables,              viz., precipitation and temeperature for analyzing their trend in the area. The trends of maximum atmospheric temperature, rainfall and rainy days are analysed statistically for meteorological data of Jagdalpur station of Bastar district, over last three decades stretching between years 1980 to 2014. The long term change in temperature, rainfall and rainy days has been analysed by correlation and linear trend analysis. The annual MMAX temperature has decreased at a rate of -0.465 °C per year during this period at Jagdalpur station and decreasing trend for rainy days during monsoonal season (June to September) is also found and is confirmed by Mann-Kendall trend test. Very weak increasing trend is observed in total month rainfall (TMRF) during season June to September. There are decreasing trends of mean monthly rainfall and south west (June - September) rainfall observed in Bastar district of Chhattisgarh. The agricultural planning and utilization of water is dependent on monsoon rainfall and more than 75% of rainfall occurring during the monsoon season is uneven both in time and space. Therefore its analysis is important for crop planning.

Pleomorphic Trypanosoma brucei are best known for their tightly controlled cell growth and developmental program, which ensures their transmissibility and host fitness between the mammalian host and insect vector. However, after long-term adaptation in the laboratory or by natural evolution, monomorphic parasites can be derived. The origin of these monomorphic forms is currently unclear. Here, we produced a series of monomorphic trypanosome stocks by artificially syringe-passage in mice, creating snapshots of the transition from pleomorphism to monomorphism. We then compared these artificial monomorphic trypanosomes, alongside several naturally monomorphic T. evansi and T. equiperdum strains, with the pleomorphic T. brucei. In addition to failing to generate stumpy forms in animal bloodstream, we found that monomorphic trypanosomes from laboratory and nature exhibited distinct differentiation patterns, which are reflected by their distinct differentiation potential and transcriptional changes. Lab-adapted monomorphic trypanosomes could still be induced to differentiate, and showed only minor transcriptional differences to that of the pleomorphic slender forms but some accumulated differences were observed as the passages progress. All naturally monomorphic strains completely fail to differentiate, corresponding to their impaired differentiation regulation. We propose that the natural phenomenon of trypanosomal monomorphism is actually a malignant manifestation of protozoal cells. From a disease epidemiological and evolutionary perspective, our results provide evidence for a new way of thinking about the origin of these naturally monomorphic strains, the malignant evolution of trypanosomes may raise some concerns. Additionally, these monomorphic trypanosomes may reflect the quantitative and qualitative changes in the malignant evolution of T. brucei, suggesting that single-celled protozoa may also provide the most primitive model of cellular malignancy, which could be a primitive and inherent biological phenomenon of eukaryotic organisms from protozoans to mammals.

In 1919–1920s, paramilitary violence was an almost natural phenomenon in Hungary, like in many other countries of Central Europe. After the dissolution of the Austro-Hungarian Empire the new right-wing government, establishing its power with the help of the Entente powers, could difficulty rule the quasi anarchistic conditions. In 1919–1921, Hungary was terrorized by irregular military formations that were formally part of the National Army, and radical right-wing soldiers committed serious crimes frequently by anti-Semitic motivations. One of the most notorious military detachment was organised by young first lieutenant of the Air Force Iván Héjjas, who, with the help of his armed militiamen, abusing the anarchistic conditions due to civil war, build up his own quasi private state in the town of Kecskemét and in its neighbourhood, the Great Hungarian Plain. His rule lasted for two years, his subordinates murdered and/or robbed hundreds of people, mainly of Jewish origin, but later they were given amnesty. Héjjas later became an influential radical right-wing politician of the Hungarian political scene in the period between the two world wars. The present research article makes an attempt to reconstruct the wave of paramilitary violence of Iván Héjjas’s detachment, and also examines of the further life of a used-to-be radical right-wing paramilitary commander and politician who gradually became member of the Hungarian political elite, despite his notorious past.

Aging is a natural phenomenon in which widowhood and disability are the major characteristics of concern. The main objective of the chapter is to sift the relationship between widowhood and disability by gender. It examines the factors affecting female elderly with the disability and measures both subjective and objective disabilities. This study is evidenced from the Kerala Ageing Survey (KAS), 2013, with a sample of 7668 elderly in which 58% are females. Three major physical disabilities, namely vision, hearing, and walking, and mental disabilities, such as cognitive impairment and depression, are to be analyzed through the data. Before that, disability trends and prevalence of both India and Kerala by age and sex are closely examined through census figures. It is revealed that elderly women are at risk of many factors compared to their male counterparts. They are vulnerable to multiple disabilities. The prevalence of disability is more among elderly females after the age of 70. The main physical problem of elderly is vision followed by movement and hearing impairment.

An unusual shape of a laccolith in the southern coastal part of the Crimea, which, when seen from a distance, resembles a huge beast bending its muzzle to the water, could well determine its name, i. e. Ayu-Dag (Crimean Tatar — Ayuv Dağ, i. e. the Bear Mount). The legend about this toponym allegorically tells about a catastrophic earthquake, which the Crimean peninsula was exposed to in the Middle Ages. This natural phenomenon was reflected in three other local legends about the Castel Mount, Yalta and Sunen-Kaya. Most likely, this calamity took place during the first war between Kaffa and Theodoro, in October-November of 1423. In many ways, it can be compared with the notorious Yalta earthquake of 1927. The archaeological works on a number of medieval sites in the region can give a good idea of the consequences of the 15th-century seismic event, which embodied the wrath of the Lord: a monastery on the south-eastern slope of the Ayu-Dag, Funa’s fort, Kalamita and Cembalo, and Basilica in Eski-Kermen.

Abstract It will not be denied that the calculations of the change of state for a gas is highly important in most engineering applications. For determining the gas’s properties such as the pressure (P), the volume (V) and the temperature (T), engineers and scientists uses the Boyle’s, Charles’s and Gay-Lussac’s (B-C-G) law of P1V1/T1=P2V2/T2. Although the B-C-G law provides the accurate property values of a gas, it give no detailed information embedded in the process when a gas changes its state. In this study, the author theoretically carried out the integrations of the partial differentials when differentiating the B-C-G law, which has not been tried by anyone up to now. The integration results of this study were thoroughly compared with the experimentally measured data and it was confirmed that the integration methods suggested in this study accurately provides the differential properties on ΔP, ΔV and ΔT. In addition to it, through the stepwise analysis of the integration of the partial differentials, it revealed that the efficiency in the change of state of a gas inherently exists higher than the Carnot cycle, which is operating between the same conditions. Therefore, the results of this study can be lead to the conclusion that all changes of state of all materials inevitably accompanies an energy loss and it is a natural phenomenon.

By invoking scientific doctrine, legal regulations and official statistics, the paper aims at assessing the actual position of females and males in labour relations in Lithuania as well as identifying the problems of the legal regulation of gender equality. The survey conducted among MRU Public Security Academy students was dedicated to disclosing the perceptions of individuals first entering the labour market about (in)equality in labour relations and experiences in the course of professional practice. To attain these objectives, certain goals were set: analysis of multiple layers of the concept of equality, legal regulation of the principle of gender equality and its inclusion in labour relations and statutory service. Furthermore, the present paper considered various trends and patterns in the implementation of the gender equality principle in labour relations, based on the analysis of the data of the Office of the Equal Opportunities Ombudsperson. Empirical research was carried out to assess the experience of students who had their professional practice in police headquarters in terms of gender inequality. Based on the performed survey that involved the students of MRU Public Security Academy, it should be concluded that the majority of students did not understand the different behaviours that could violate an individual’s rights in terms of the equality of men and women. When responding to certain questions, the majority of respondents indicated that gender inequality in Lithuania existed only to the extent it occurred naturally; however, when responding to other questions, the majority stated that there were numerous situations during their practice when they experienced discrimination (i.e. preferential treatment of one of the genders, abuse due to gender etc.). This can lead to the conclusion that violations of gender equality committed on certain grounds are perceived as a natural phenomenon resulting from natural differences between the sexes and because of this, certain flawed behaviour is justified. This results in fewer opportunities for individuals to report violations to responsible institutions and thus ensure the protection of their rights as well as to share their experiences with other individuals and, as a result, educate them.

Purpose. The article is aimed to substantiate the view on the phenomenon of laughter as a subject of semiotic analysis, which leads to the following tasks: to reveal the possibilities of semiotics application in the study of laughter nature; to analyze the phenomenon of laughter as a cultural and natural phenomenon, as a sign and as an attribute; to consider the place of laughter in culture, which is understood as a sign system. Theoretical basis. The semiotic approach proceeds from the fact that human lives in the world of signs, all the surrounding reality can be interpreted as a sign system. The basic concept of semiotics is the concept of a sign. The theoretical basis of the article is understanding the culture as a sign-symbolic system. Laughter is considered as a phenomenon ontologically rooted in human culture. At the same time, laughter is on the edge of culture. The research is based on the work of semiotic authors, cultural researchers, and the researchers of laughter. Originality. The originality lies in the application of the semiotic method to the research of laughter phenomenon, consideration of the dialectics of natural and cultural, signedness and non-signedness, manifested in the phenomenon of laughter. Conclusions. Laughter is considered as a psychophysiological phenomenon (attribute) and as a cultural phenomenon (sign). Laughter acts as an emotional manifestation, a physiological reaction, but socially and culturally mediated. In any case, laughter indicates an emotional or cognitive state of a human. Laughter acts as a process and result of the interpretation of a sign, a reaction to a sign. Laughter is a form and a means of communication. Being a natural phenomenon, in the process of social evolution, laughter acquires signedness, is integrated by culture as a sign system, and, at the same time, maintains a connection with nature. Thus, laughter occupies an ambivalent position between nature and culture. In the phenomenon of laughter, the dual state of human is revealed. In laughter, boundaries are blurred, the unity and opposition of natural and cultural, biological and social, soul and body, thought and feeling, sign and attribute are manifested.

Abstract This paper purposes a new type of hybrid technique depends on lightning search algorithm (LSA) and recursive least square (RLS) named as LSA-RLS to overcome the harmonic estimation issues in time varying modern power system signals buried with noises. LSA is based on a natural phenomenon of lightning. It consists of three types of projectiles: transition, space and lead projectiles. Transition projectiles create population, space projectiles do the exploration and the lead projectiles do the work of exploitation and find the optimal solution. The basic LSA algorithm is mixed with RLS algorithm in an adaptive way to estimate the states of the harmonic signals. Simulation and validation are made with real time data obtained from a converter fed D.C motor drive. The efficacy of the proposed algorithm is verified by comparing the simulation results of recently reported algorithms such as particle swarm optimization (PSO), differential evolution (DE), bacteria foraging optimization (BFO), gravity search algorithm hybridized recursive least square method (GSA-RLS). It is verified that proposed (LSA-RLS) technique is the best in terms of computational time, convergence, accuracy.
