description: Aperiodic dynamics which is nonchaotic is realized on Strange Nonchaotic attractors (SNAs). Such attractors are generic in quasiperiodically driven nonlinear systems, and like strange attractors, are geometrically fractal. The largest Lyapunov exponent is zero or negative: trajectories do not show exponential sensitivity to initial conditions. In recent years, SNAs have been seen in a number of diverse experimental situations ranging from quasiperiodically driven mechanical or electronic systems to plasma discharges. An important connection is the equivalence between a quasiperiodically driven system and the Schrödinger equation for a particle in a related quasiperiodic potential, giving a correspondence between the localized states of the quantum problem with SNAs in the related dynamical system. In this review we discuss the main conceptual issues in the study of SNAs, including the different bifurcations or routes for the creation of such attractors, the methods of characterization, and the nature of dynamical transitions in quasiperiodically forced systems. The variation of the Lyapunov exponent, and the qualitative and quantitative aspects of its local fluctuation properties, has emerged as an important means of studying fractal attractors, and this analysis finds useful application here. The ubiquity of such attractors, in conjunction with their several unusual properties, suggest novel applications.

description: Nowadays, there is no exact method for determining the optimal speed limit in winter and the problems associated with winter speed limit has not yet been addressed in Hokkaido. Therefore, this study aims at determining the optimal winter speed limit through the application of a cost analysis and by analysis of effects of road and traffic conditions. Initially, a cost analysis of travel time costs, vehicle operating costs, pollution costs, and cost of accidents was applied to determine optimal average speed on the basis of the minimum total cost. Then, the effects of road and traffic conditions were calculated by regression analysis. Finally, the optimal winter speed limits were achieved by adding those effects to the optimal average speed. For the purpose of reliability, we applied a sensitivity analysis to the model. We found that our model was reliable and the results are appropriate and sustainable long term.

description: A multipole expansion analysis is applied to 1420 MHz radio continuum images of supernova remnants (SNRs) in order to compare Type Ia and core collapse (CC) SNRs. Because the radio synchrotron emission is produced at the outer shock between the SNR and the ISM, we are investigating whether the ISM interaction of SNRs is different between Type Ia and CC SNRs. This is in contrast to previous investigations, which have shown that Type Ia and CC SNRs have different asymmetries in the X-ray emission from their ejecta. The sample consists of 19 SNRs which have been classified as either Type Ia or CC. The quadrupole and octupole moments normalized to their monopole moments (total emission) are used as a measure of asymmetry of the emission. A broad range (by a factor of ~1000) is found for both quadrupole and octupole normalized moments. The strongest correlation we find is that large quadrupole moments are associated with large octupole moments, indicating that both serve as similar indicators of asymmetry. The other correlation we find is that both moments increase with SNR age or radius. This indicates that interstellar medium structure is a strong contributor to asymmetries in the radio emission from SNRs. This does not seem to apply to molecular clouds, because we find that association of a SNR with a molecular cloud is not correlated with larger quadrupole or octupole moments.

description: The paper reviews the evolution of U.S. cotton transportation and logistics patterns over the last three decades. There have been many forces of change over this time period, with the largest change being a shift from primarily domestic market destinations to the international market. We describe the pre-1999 system and flow patterns when domestic consumption of U.S. cotton was dominant. We contrast this with current flow patterns as measured by available secondary export data and a sample of survey data from Texas cotton warehouses. The survey data show similar shipment destinations and modes of transportation for Texas cotton as observed in the Mid-1990s. The main difference is the increased percentage of export destinations, reflecting the transformation of the U.S. cotton industry into an export industry.

description: The advancement of technology makes the companies to reinvente themselves quite often, in order to provide increasingly demanding customers. The company may provide a product or a service to a customer million times, however, when the company provides a product / service with defect, they will be always remembered for this issue. It is very hard finding a company which has never commited a mistaken into delivery a product with mistaken to a customer. Most of the time it happens, because the employees are overwhelmed, a department did not understand properly the customer requirements, lack of standards process and many others. We are already in the 2020’s and everyday more and more the business world have stronger competitors. If your company does not provide and delivery the requested product or service on time, be sure that there will be another company which will do it and your business may have serious problems. With the advance of the internet, it’s possible to know what the customers wants and how to target them and also the internet it is a tool which may bankrupt with a company. If a customer is not satisfied with which he got, he may put a photo in the social medias and the papers of your company may go down until you have economical problems. Nevertheless, much of the impacts can be avoided. It depends on the capacity of the company to invest in the Quality Management department to provide the Continuous Improvement in their internal processes. A company without process may fail and once it happens, the competitors will be very happy.
Does a Nambu-Goto wall emit gravitational waves? -- Cylindrical Nambu-Goto wall as an example of gravitating non-spherical walls --

description: Gravitational field of a cylindrical Nambu-Goto wall in the vacuum spacetime is considered in order to clarify the interaction between Nambu-Goto membranes and gravitational waves. If one neglects the emission of gravitational waves by the wall motion, the spacetime becomes singular. It is also shown that the emission of gravitational waves does occur by the motion of the cylindrical wall if the initial data is singularity free. The energy loss rate due to radiation of gravitational waves agrees with that estimated from the test wall motion and the quadrupole formula for the gravitational wave emission. This is quite different from the oscillatory behavior of gravitating Nambu-Goto membranes: the presence of gravity induces the wall to lose its dynamical degree of freedom.

description: In this paper, we study one of the most important railroad optimization problems, the crew scheduling problem, in the context of North American railroads. Crew scheduling for North American railroads is very different from that of European railroads, which has been well studied. The crew scheduling problem is to assign crew (train operators) to scheduled trains over a time horizon (generally a week) at minimal cost while honoring several operational and contractual requirements. Each North American Class I railroad spends at least a billion dollars in crew costs annually and does not have any decision support system available that can assist it in all levels of decision making: tactical, planning, and strategy. Indeed, all decisions related to crew are made manually, thereby leaving sufficient room for improvement. We have developed a network-flow based crew-optimization model that has applications in all levels of decision making in crew scheduling: tactical, planning, and strategy. Our network-flow model maps the assignment of crew to trains as the flow of crew on an underlying network where different crew types are modeled as different commodities in this network. We formulate the crew assignment problem as an integer-programming problem on this network, which allows this problem to be solved to optimality. We also develop several highly efficient algorithms using problem decomposition and relaxation techniques, where we use the special structure of the underlying network model to obtain significant speed-ups. We present very promising computational results of our algorithms on the data provided by a major North American railroad. Our network flow model is likely to form a backbone for a decision-support system for crew scheduling.

description: In this letter we investigate the pulsational properties of ZZ Ceti stars on the basis of new white dwarf evolutionary models calculated in a self-consistent way with the predictions of time dependent element diffusion and nuclear burning. In addition, full account is taken of the evolutionary stages prior to the white dwarf formation. Emphasis is placed on the trapping properties of such models. By means of adiabatic, non-radial pulsation calculations, we find, as a result of time dependent diffusion, a much weaker mode trapping effect, particularly for the high-period regime of the pulsation g-spectrum. This result is valid at least for models with massive hydrogen-rich envelopes. Thus, mode trapping would not be an effective mechanism to explain the fact that all the high periods expected from standard models of stratified white dwarfs are not observed in the ZZ Ceti stars.

description: The present study was conducted to assess the availability of Black Bengal breeding bucks in five districts from the Northern part (Lalmonirhat and Rangpur), Central part (Tangail and Mymensingh) and Southern part (Khulna) of Bangladesh and also to explore the relationship between distance of does from these breeding bucks and type of scarcity. The data were collected using a pre-tested questionnaire from 100 goat rearers of 100 villages in five districts. In this study, the selected characteristics of the respondents and other factors on the availability of Black Bengal breeding bucks were considered as independent variable whereas type of scarcity was considered as dependent variable. The buck and doe ratios were 1:164, 1:138, 1:114, 1:127 and 1:96 in Lalmonirhat, Rangpur, Tangail, Khulna and Mymensingh district, respectively. The pooled buck and doe ratio was 1:128. More than 70% farmers faced severe shortage of breeding bucks for serving their does in the above districts which ultimately represent the overall situation of the country. Almost all farmers (100%) had to depend on natural mating to serve their does except the farmers of Mymensingh where 12% farmers depended on artificial insemination in goat. It was observed that type of scarcity had significantly positively correlated (0.933) with distance of does from breeding bucks. This also indicated that type of scarcity gradually reached to severe level which may create the inbreeding depression in goat breeding.

description: The present study was conducted to isolate the causal agent of necrotic enteritis (NE) from broiler chickens. A total of 50 jejunal samples from necropsied broiler chickens were collected for isolation of Clostridium perfringens, the causal agent of NE. The novel method for isolation of Clostridium perfringens was stab culture in association with pouring of olive oil on the surface of the stab culture. The collected samples in nutrient broth were kept in a candle jar and incubated for 24 hrs at 37°C. For maintenance of anaerobic condition olive oil (2-3 cm) were poured on surface of culture broth in test tube. In Gram's staining, the morphology of the isolated bacteria was Gram-positive, rod-shaped, anaerobic, spore-forming single or paired in arrangement. The addition of olive oil on the surface of stab culture was effective for the growth of Clostridium perfringens. The characterization of Clostridium perfringens was then performed by other routine cultural study, staining procedure and different types of biochemical tests. The occurrence of necrotic enteritis was 8%

description: Every manufacturing process has the necessity for an optimal production schedule. The scheduling though depends on a diverse range of internal and external parameters. These have to be defined and optimised to best queue orders accordingly. In this thesis the planning process of a transfer producing company, the Franz Barta Gmbh, is analysed and optimisations implemented, to reduce the required know-how and time needed to conduct the process. Due to pending retirements, in the planning division, the threat of losing knowledge and hence not being able to efficiently schedule grows. Methods used to simulate the influencing factors are analysed if suited to aid the process. Generally, the more precise and accurate methods are the better they incorporate all influences, terminating in complex models. Due to the high interdependencies of the different parameters at the company the digitally visualisation approach was chosen to reach the goal. Consequentially, the different workstations needed to have a thorough information flow implemented and where analysed and adapted according to the Lean and JIT philosophy. All resulting in reduced planning times, through distributing responsibilities and tasks to the separate division.

description: Die vorliegende Masterarbeit untersucht den Einfluss von Drag auf das Körpererleben und die Sexualität queerer Menschen und ergründet Potentiale und Grenzen dieser Praxis. Dafür werden queere Drag-Performer*innen im deutschsprachigen Raum mittels qualitativer leitfadengestützer Interviews zu ihrer Drag-Praxis befragt. Ziel dieser Studie ist es herauszufinden, wie sich diese auf ihr Körpererleben und ihre Sexualität auswirkt und welche Aspekte hierbei eine Rolle spielen. Die Auswertung der fünf Interviews erfolgt anhand der inhaltlich strukturierenden qualitativen Inhaltsanalyse angelehnt an Kuckartz und Rädiker (2022). Die Ergebnisse dieser Studie verweisen darauf, dass Drag positive Auswirkungen auf das Körpererleben hat, indem durch äußerliche Veränderung spielerisch Gestaltungsmöglichkeiten des Geschlechtsausdrucks ausgelotet werden. Insbesondere bei nicht-binären Praktizierenden kann dies zu einem kongruenteren Geschlechtserleben führen. Die Bühnenerfahrung verbunden mit anerkennendem Zuspruch seitens des Publikums und die Verbundenheit mit einer (queeren) Community wirken sich hierbei bestärkend aus. Ein zentraler Aspekt des Einflusses von Drag auf die Sexualität der Teilnehmenden äußert sich in der erotischen Bezugnahme auf den eigenen Körper im Rahmen von Drag Performances. Hierdurch werden nicht-normative queere Körper in Anlehnung an Muñoz (1999) einem disidentifikatorischen Prozess unterzogen, wodurch der Körper sich als begehrenswert erfahren lässt. Gleichzeitig wirken Erfahrungen der mehrfachen Marginalisierung innerhalb queerer Communities weiter und beschränken neben Erfahrungen der Dragfeindlichkeit das positive Potential dieser Praxis.

description: The 500-meter Aperture Spherical Radio Telescope(FAST) has an active reflector. During the observation, the reflector will be deformed into a paraboloid of 300-meters. To improve its surface accuracy, we propose a scheme for photogrammetry to measure the positions of 2226 nodes on the reflector. And the way to detect the nodes in the photos is the key problem in photogrammetry. This paper applies Convolutional Neural Network(CNN) with candidate regions to detect the nodes in the photos. The experiment results show a high recognition rate of 91.5%, which is much higher than the recognition rate of traditional edge detection.

description: We introduce a parametrically driven Ginzburg-Landau (GL) model, which admits a gradient representation, and is subcritical in the absence of the parametric drive (PD). In the case when PD acts uniformly in space, this model has a stable kink solution. A nontrivial situation takes places when PD is itself subject to a kink-like spatial modulation, so that it selects real and imaginary constant solutions at +infinity and -infinity. In this situation, we find stationary solutions numerically, and also analytically for a particular case. They seem to be of two different types, viz., a pair of kinks in the real and imaginary components, or the same with an extra kink inserted into each component, but we show that both belong to a single continuous family of solutions. The family is parametrized by the coordinate of a point at which the extra kinks are inserted. Solutions with more than one kink inserted into each component do not exist. Simulations show that the former solution is always stable, and the latter one is, in a certain sense, neutrally stable, as there is a special type of small perturbations that remain virtually constant in time, rather than decaying or growing (they eventually decay, but extremely slowly).

description: Artificial Intelligence (AI) is transforming tax compliance by improving fraud detection, increasing revenue collection, and streamlining tax audits. This study investigates AI’s role in reducing tax evasion and enhancing tax administration efficiency from 2020 to 2024. Using secondary data analysis, statistical evaluations, and trend assessments, we assess AI’s impact on revenue generation, fraud detection, and audit processes. The findings reveal a significant increase in AI-assisted revenue from $20 billion in 2021 to $120 billion in 2024, with a tax revenue growth rate of 7%. AI-driven fraud detection improved from identifying 14.7% of evasion cases in 2021 to 55.0% in 2024, confirming AI’s effectiveness in detecting tax fraud. Statistical analysis, including regression modeling (R² = 0.89), shows a strong correlation between AI investment and tax revenue growth, while chi-square tests confirm AI's significant role in fraud detection (p < 0.05). AI-assisted audits also reduced audit duration from 30 to 15 days and improved accuracy from 85% to 95%. Despite its benefits, AI implementation faces challenges such as high investment costs, data privacy concerns, and taxpayer resistance. To maximize AI’s potential, governments should establish standardized regulatory frameworks, invest in AI-driven tax education, and integrate ethical AI practices in compliance monitoring. Future research should explore AI’s adaptability across diverse tax jurisdictions and its long-term economic impact.

description: Context. Spectroscopy of exoplanet atmospheres at high resolving powers is rapidly gaining popularity to measure the presence of atomic and molecular species. While this technique is robust against contaminant absorption in the Earth's atmosphere, the non stationary stellar spectrum creates a non-negligible source of noise that can alter or even prevent detection. Aims. We aim at using three-dimensional stellar simulations to directly remove the signature of the star from observations, and prior to cross correlation with templates for the planet's atmosphere Methods. We compute synthetic spectra from 3D simulations of stellar convection and we couple them with an analytical model reproducing the correct geometry of a transiting exoplanet. We apply the method to HD 189733, and analyse transmission and emission spectroscopy of its hosted exoplanet. In addition, we analyse emission spectroscopy of the non transiting exoplanet 51 Pegasi b. Results. We find a significant improvement in the planet detectability when removing the stellar spectrum with our method. We show that the method is superior to a simple parametrisation of the stellar line profile or to the use of one-dimensional stellar models. This is due to the intrinsic treatment of convection, which allows us to correctly reproduce asymmetric spectral lines, and model center-to-limb variation and Rossiter-McLaughlin effect. In the case of 51 Pegasi b, we succeed at confirming a previous tentative detection of the planet's K-band spectrum due to the improved suppression of stellar residuals. Future high-resolution observations will benefit from the synergy with stellar spectroscopy, and can be used to test the correct modelling of physical processes in stellar atmospheres. We highlight key improvements in modelling techniques and knowledge of opacity sources to extend this work to shorter wavelengths and later-type stars.

Dieses Fundament soll die Verknüpfung der benannten Begriffe zur Legitimation der Rahmenbedingungen eines solchen Workshops ermöglichen. Daraufhin wird ein mögliches Konzept für einen Workshop ohne definierte Zielgruppe vorgestellt. Die Vorgehensweise gestaltet sich folgendermaßen: der Ablauf und der daraus folgende Effekt orientiert sich an theoretischer Grundlage (u.a. Anklam/Reyer/Meyer 2018; Meis/Mies 2018). Für die Umsetzung der darin beschriebenen relevanten Teile eines Workshops werden theaterpädagogische Übungen und Methoden zu Rate gezogen, die in ihrer Ausführung und Wirkung (inklusive didaktischer Ziele) beschrieben werden. Es wird bei jeder Übung Bezug auf die Reflexion und Wirkung der Lernziele von Macht als Thema und Ressourcenförderung als Leitziel genommen. Diese Bezüge werden schließlich in Zusammenhang mit den Leitzielen des Empowerments gebracht. In Kombination bieten TP und Empowerment-Arbeit einen geeigneten konzeptionellen Rahmen für einen Workshop zur Ressourcenförderung in der Sozialen Arbeit. Der Begriff Macht als Zugang zu theaterpädagogischen Übungen, Ressourcenarbeit und empowernden Prozessen ist wissenschaftlich in allen benannten Teilbereichen verortbar und somit legitim. Der Workshop MACHT was draus! mit theaterpädagogischen Übungen kann in der Sozialen Arbeit ihren Adressat*innen Gedankenanstöße geben, den eigenen Ressourcenzugang zu reflektieren und ihn dadurch teilweise zu aktivieren.

A total of 236 water buffaloes were examined, among them 144 (61.02%) buffaloes were found infected with one or more species of gastro-intestinal parasites. Nine species of gastro-intestinal parasites were identified, of them four species were trematodes, namely, Paramphistomum cervi (29.24%), Fasciola gigantica (22.46%), Schistosoma indicum (1.27%), Schistosoma spindale (0.85%); three species were nematodes, namely, Toxocara vitulorum (2.54%), Strongyles (0.85%), Strongyloides sp. (0.42%) and two species were protozoa, namely, Eimeria sp. (3.39%) and Balantidium coli (37.29%). No cestode was detected. Among the gastro-intestinal parasites mixed infection was common. In this investigation, prevalence of parasites in relation to age, sex and seasonal dynamics was also studied. Significantly (p<0.01) higher prevalence of gastro-intestinal parasites was observed in rainy season followed by summer and winter seasons. Males and females were almost equally (odd ratio 1.08) susceptible to gastro-intestinal parasitic infection. In the age groups, young (< 2 to 5 years) were mostly (p<0.01) susceptible to gastro-intestinal parasites. In the present study, EPG (Egg/cyst Per Gram of Feces) was also determined. The range of EPG varied from 100-5000 among the identified parasites. The results of the present investigation revealed that the prevalence of gastro-intestinal parasites in buffaloes is very common and quite severe. It is imperative that integrated strategies and measures be taken to control gastrointestinal parasitic infections in buffaloes in kurigram district and elsewhere in Bangladesh.

description: We use a quantum path integral approach to describe the behavior of a microwave cavity coupled to a dissipative mesoscopic circuit. We integrate out the mesoscopic electronic degrees of freedom to obtain a cavity effective action at fourth order in the light/matter coupling. By studying the structure of this action, we establish sufficient conditions in which the cavity dynamics can be described with a Lindblad equation. This equation depends on effective parameters set by electronic correlation functions. It reveals that the mesoscopic circuit induces an effective Kerr interaction and two-photon dissipative processes. We use our method to study the effective dynamics of a cavity coupled to a double quantum dot with normal metal reservoirs. If the cavity is driven at twice its frequency, the double dot circuit generates photonic squeezing and non-classicalities visible in the cavity Wigner function. In particular, we find a counterintuitive situation where mesoscopic dissipation enables the production of photonic Schrödinger cats. These effects can occur for realistic circuit parameters. Our method can be generalized straightforwardly to more complex circuit geometries with, for instance, multiple quantum dots, and other types of fermionic reservoirs such as superconductors and ferromagnets.

description: Immer wieder berichten Mitglieder der linken feministischen Szene, die in Armut aufgewachsen sind oder in der Arbeiter*innenklasse sozialisiert wurden, von klassistischen Strukturen innerhalb der Szene. Die Auseinandersetzung mit dieser Form von Diskriminierung findet aber laut Kritiker*innen kaum und nicht systematisch genug statt. Diese Arbeit beleuchtet mit Hilfe von leitfadengestützten narrativen Interviews mit Mitgliedern der linken feministischen Szene die aktuelle Wahrnehmung, Diskussion und Praxis im Umgang mit Klassismus innerhalb der Szene. Die Ergebnisse sollen nicht nur zur theoretischen Weiterentwicklung des Verständnisses von Klassismus beitragen, sondern auch konkrete Impulse für die Gestaltung inklusiverer feministischer Räume liefern sowie zur Förderung von Solidarität und Unterstützung zwischen Personen unterschiedlicher Klassen beitragen.

description: This study was designed to investigate the prevalence and pathology of mite infestation in the street dog at Dinajpur municipality area, Dinajpur, Bangladesh, during June to September, 2010 using simultaneous clinical and histopathological examination and identification. A total of 48 street dogs (27 male and 21 female) were examined, among them 30(62.5%) were infested with one or more species of mites. Two species of mites were identified as Sarcoptes scabiei var.canis and Demodex canis. The range of mites burden was 1-5 per square inch of heavily infested area. Mean mites burden was high in case of Sarcoptes scabiei var.canis (1.5±0.2) followed by Demodex canis (0.6±0.1). Prevalence was higher in the dog of 1-2 years of age (68.9%) than in the dog of >2-4 years of age (52.6%). Infestation of mite was significantly (p<0.05) higher in male (66.6%) than female (57.1%) dog. Mite infestation was more prevalent in the poor healthy dog (75.7%) than the normal healthy dog (33.3%). Prevalence of mites infestation was significantly (p<0.05) higher in back region (68.1%) followed by face and neck (66.6%) and abdomen (58.3%) and lowest in thigh and groin (40.0%). Grossly, alopecia, rough, dry leathery and corrugation of skin, erythema, pastules, crusts and pruritus were found. Microscopically, it was characterized by acanthosis, slight hyperkeratosis, formation of hyperplastic rete-pegs, destruction of dermis and epidermis, hyperplastic changes in sweat glands, sebaceous glands and hair follicular cells, pyogranuloma in papillary layer and hair follicles and infiltration of neutrophils, oeosinophils, lymphocytes and few macrophages. The results indicate that street dogs of Dinajpur municipality area are very much susceptible to mite infestation. The mite produces clinico- pathological effects on dog, which may be the serious threat to public health.
Rheology of active polar emulsions: from linear to unidirectional and unviscid flow, and intermittent viscosity

description: The rheological behaviour of an emulsion made of an active polar component and an isotropic passive fluid is studied by lattice Boltzmann methods. Different flow regimes are found by varying the values of shear rate and extensile activity (occurring, e.g., in microtubule-motor suspensions). By increasing activity, a first transition occurs from linear flow regime to spontaneous persistent unidirectional macro-scale flow, followed by another transition either to (low shear) intermittent flow regime with coexistence of states with positive, negative, and vanishing apparent viscosity, or to (high shear) symmetric shear thinning regime. The different behaviours can be explained in terms of the dynamics of the polarization field close to the walls. A maximum entropy production principle selects the most likely states in the intermittent regime.
Canonical Quantization of Gravity without "Frozen Formalism"

description: We write down a quantum gravity equation which generalizes the Wheeler-DeWitt one in view of including a time dependence in the wave functional. The obtained equation provides a consistent canonical quantization of the 3-geometries resulting from a ``gauge-fixing'' (3 + 1)-slicing of the space-time. Our leading idea relies on a criticism to the possibility that, in a quantum space-time, the notion of a (3 + 1)-slicing formalism (underlying the Wheeler-DeWitt approach) has yet a precise physical meaning. As solution to this problem we propose of adding to the gravity-matter action the so-called {\em kinematical action} (indeed in its reduced form, as implemented in the quantum regime), and then we impose the new quantum constraints. As consequence of this revised approach, the quantization procedure of the 3-geometries takes place in a fixed reference frame and the wave functional acquires a time evolution along a one-parameter family of spatial hypersurfaces filling the space-time. We show how the states of the new quantum dynamics can be arranged into an Hilbert space, whose associated inner product induces a conserved probability notion for the 3-geometries. Finally, since the constraints we quantize violate the classical symmetries (i. e. the vanishing nature of the super-Hamiltonian), then a key result is to find a (non-physical) restriction on the initial wave functional phase, ensuring that general relativity outcomes when taking the appropriate classical limit. However we propose a physical interpretation of the kinematical variables which, based on the analogy with the so-called {\em Gaussian reference fluid}, makes allowance even for such classical symmetry violation.

description: An understanding of past, from which we learn, and present, through which we observe, population dynamics is necessary for development planning for a country. This paper studies this present facts of and past trends in population dynamics paying particular attention to the major demographic variables of population, fertility, mortality, and migration profiles in the last two decades with an assessment of various demographic data sources in Bangladesh. In doing so various literatures were reviewed and secondary data were generated mostly from international sources, like database of the United Nations, Population Reference Bureau, US Census Bureau etc., and partly from national sources, like population census, Bangladesh demographic and health survey etc., which are the major sources of demographic data for Bangladesh. The study observes that the demographic indicators of Bangladesh have shown considerable development during the last two decades. Though the population increased in size but growth showed a declining trend. The total fertility rate declined from 3.96 children per woman during 1990- 1995 to 2.36 during 2005-2010, and infant mortality and under-five mortality rates almost halved during the same period. Life expectancy at birth recently reached to 69 years from 56 years in 1990. Moreover, international outmigration showed an increasing trend with a very low rate for female.
