It is the result of multiple effects of innate (endogenous) and exogenous etiological factors with different degrees of influence. The degree of hallux valgus deformity is usually assessed by radiological values of hallux valgus (HV) and intermetatarsal (IM) angles. The aim of the paper is to justify the definition of hallux valgus deformity as a function of one angle, (HVA or IMA), and then to determine the functional connection and the most suitable function equalizing the values of the angles IMA and HVA. As hallux valgus is a double angulation deformity, the analytically determined connection between the HVA and IMA angles reduces the study of the deformity to the study of function with one argument, and makes the analysis of deformity changes before and after operative treatment simpler. For the determined connections between the angles, the values of linear proportionality coefficients and regression coefficients of corresponding linear functions of analytical equalization of the value of the IM angle and the degree of deformity for a given value of the HV angle were experimentally determined. The obtained results were checked on a sample of 396 operatively treated hallux valgus deformities. The presented analytical approach and the obtained functional links of IMA and HVA enable quantitative observation of the change in the degree of deformity based on the radiologically determined value of these angles, and the established nonlinear function will be useful for evaluating the expected value of the IM angle and the degree of deformity based only on the measured value of the HV angle. .展开更多

This is the common feature of all life forms in the universe and the general law of the universe. The unity of the universe includes the unity of all universal forces which consist of two kinds, physical force and life force. The former includes bonding force, strong interaction, quark confinement, weak interaction, electromagnetic interaction and gravitational interaction and is also called four-seasonal structure. The latter lies inside the life forms, combines life beings and pushes the four-seasonal movement and rise-fall movement inside life forms. Life force includes transverse four-seasonal force, longitudinal four-seasonal force, four-gradation force, life being structural force and four-gradation rise-fail force. All these forces are united to form a complex life force system. Life force is also a compound, integral, long-range and automatically-closed four-seasonal force. Life being structural force is a force that connects all parts of a life being to make it an integral being.

The author has continued investigating the extraordinary (paradigm-breaking) hypothesis of formal-axiological interpreting Newton’s mathematical principles of natural philosophy and, thus, has arrived to discrete mathematical modeling a system of formal axiology of nature by extracting and systematical studying its proper algebraic aspect. Along with the proper algebraic machinery, the axiomatic (hypothetic-deductive) method is exploited in this investigation systematically. The research results are the followings. 1) The Third Newton’s Law of mechanics has been modeled by a formal-axiological equation of two-valued algebraic system of metaphysics as formal axiology. (Precise defining the algebraic system is provided.) The formal-axiological equation has been established (and examined) in this algebraic system by accurate computing compositions of relevant evaluation-functions. Precise tabular definitions of the evaluation-functions are given. 2) The wonderful formula representing the Third Newton’s Law (in the relevant physical interpretation of the formal theory Sigma-V) has been derived logically in Sigma-V from the presumption of a-priori-ness of knowledge. A precise axiomatic definition of the nontrivial notion “a-priori-ness of knowledge” is given. The formal derivation is implemented in strict accordance with the rigor standard of D. Hilbert’s formalism;hence, checking the formal derivation submitted in this article is not a difficult task. With respect to proper theoretical physics, the formal inference is a nontrivial scientific novelty which has not been discussed and published elsewhere yet.展开更多

Unlike minerals which are by law vested in the government and can only be extracted by it and not the citizenry, wildlife and forestry are resources that the citizens may utilize in their day to day lives to meet their needs. Apart from their consumptive uses, there are also non-consumptive uses and values of wild animals and forests;such as their intrinsic ecological value as gene banks, as well as their scenic value for viewing. These are essentially conventional values and uses. They are largely formal and universal ones that are universally obtaining across </span></span></span><span><span><span>the </span></span></span><span><span><span>world irrespective of the levels of civilization or cultural identity, and </span></span></span><span><span><span>are </span></span></span><span><span><span>even compatible with modernity.

These are what are in this paper referred to as “traditional customary uses”. These uses are largely informal, rudimentary and archaic. They are nevertheless critical in the endemic African way of life and represent the inextricable rudimentary technologically bereft relationship between the African people and their natural resources. Under the country’s existing laws, some of these uses are prohibited and criminal sanctions prescribed to enforce their proscription, hence cannot be enjoyed or practiced. There are however others that the law</span></span></span><span><span><span> has</span></span></span><span><span><span> either expressly allowed, or not prohibited, hence may be lawfully enjoyed or practiced. These are what this paper has referred to as the legally permissible traditional customary uses;and are the ones that are its subject.

This therefore means that hunting is illegal, as legal prohibition has in effect prohibited all and any form of off-take or killing of wildlife.

This in effect means that the socio-cultural and spiritual uses of wildlife though legally permissible, will be enjoyed, provided it is not for witchcraft purposes. With regard to forests, this author has identified the following five as their legally permissible traditional customary uses under Kenyan law: Socio-cultural and spiritual (consumptive and non-consumptive)</span><span> use, other than for witchcraft;use in herbal folk medicine, other than for witchcraft;use for human food and livestock fodder;use for firewood;and use as raw material in construction and traditional craft. Notably, in Kenya, traditional customary use is subject to the existing legal prohibition on witchcraft. Further, while it is the legally permissible use category that is the focus of this paper, the author nevertheless discusses the prohibited traditional customary uses as well. This paper is based on literature survey as well as data obtained from the author’s previous research whose primary data and findings have been published in recent times. It also draws from the documented research and diverse documented views of other commentators on the subject.展开更多

A second follow-up paper will deal with its internal structure. We hypothesize that black holes are 4-dimensional spatial, steady state, self-contained spheres filled with black-body radiation. As such, the event horizon marks the boundary between two adjacent spaces, 4-D and 3-D, and there, we consider the radiative transfers involving black- body photons. We generalize the Stefan-Boltzmann law assuming that photons can transition between different dimensional spaces, and we can show how for a 3-D/4-D interface, one can only have zero, or net positive, transfer of radiative energy into the black hole. We find that we can predict the temperature just inside the event horizon, on the 4-D side, given the mass, or radius, of the black hole. For an isolated black hole with no radiative heat inflow, we will assume that the temperature, on the outside, is the CMB temperature, T2 = 2.725 K. We take into account the full complement of radiative energy, which for a black body will consist of internal energy density, radiative pressure, and entropy density. It is specifically the entropy density which is responsible for the heat flowing in. We also generalize the Young- Laplace equation for a 4-D/3-D interface. We derive an expression for the surface tension, and prove that it is necessarily positive, and finite, for a 4-D/3-D membrane. This is important as it will lead to an inherently positively curved object, which a black hole is. With this surface tension, we can determine the work needed to expand the black hole. We give two formulations, one involving the surface tension directly, and the other involving the coefficient of surface tension. Because two surfaces are expanding, the 4-D and the 3-D surfaces, there are two radiative contributions to the work done, one positive, which assists expansion. The other is negative, which will resist an increase in volume. The 4-D side promotes expansion whereas the 3-D side hinders it. At the surface itself, we also have gravity, which is the major contribution to the finite surface tension in almost all situations, which we calculate in the second paper. The surface tension depends not only on the size, or mass, of the black hole, but also on the outside surface temperature, quantities which are accessible observationally. Outside surface temperature will also determine inflow. Finally, we develop a “waterfall model” for a black hole, based on what happens at the event horizon. There we find a sharp discontinuity in temperature upon entering the event horizon, from the 3-D side. This is due to the increased surface area in 4-D space, AR(4) = 2π2R3, versus the 3-D surface area, AR(3) = 4πR2. This leads to much reduced radiative pressures, internal energy densities, and total energy densities just inside the event horizon. All quantities are explicitly calculated in terms of the outside surface temperature, and size of a black hole. Any net radiative heat inflow into the black hole, if it is non-zero, is restricted by the condition that, 0cdQ/dt FR(3), where, FR(3), is the 3-D radiative force applied to the event horizon, pushing it in. We argue throughout this paper that a 3-D/3-D interface would not have the same desirable characteristics as a 4-D/3-D interface. This includes allowing for only zero or net positive heat inflow into the black hole, an inherently positive finite radiative surface tension, much reduced temperatures just inside the event horizon, and limits on inflow.展开更多

Although the county-level governance mode is stable, its evolution has laws to follow. Generally speaking, the rules are that the scale of the county government is small for a long time and the governmental functions in the long term are fixed. The roles of the clan organizations in the social governance are increasingly strengthened and the slow development and roles of other social organizations outside the clan organizations are increasing.展开更多

文摘The article is devoted to hitherto never undertaken applying an almost unknown logically formalized axiomatic epistemology-and-axiology system called “Sigma-V” to the Third Newton’s Law of mechanics. The author has continued investigating the extraordinary (paradigm-breaking) hypothesis of formal-axiological interpreting Newton’s mathematical principles of natural philosophy and, thus, has arrived to discrete mathematical modeling a system of formal axiology of nature by extracting and systematical studying its proper algebraic aspect. Along with the proper algebraic machinery, the axiomatic (hypothetic-deductive) method is exploited in this investigation systematically. The research results are the followings. 1) The Third Newton’s Law of mechanics has been modeled by a formal-axiological equation of two-valued algebraic system of metaphysics as formal axiology. (Precise defining the algebraic system is provided.) The formal-axiological equation has been established (and examined) in this algebraic system by accurate computing compositions of relevant evaluation-functions. Precise tabular definitions of the evaluation-functions are given. 2) The wonderful formula representing the Third Newton’s Law (in the relevant physical interpretation of the formal theory Sigma-V) has been derived logically in Sigma-V from the presumption of a-priori-ness of knowledge. A precise axiomatic definition of the nontrivial notion “a-priori-ness of knowledge” is given. The formal derivation is implemented in strict accordance with the rigor standard of D. Hilbert’s formalism;hence, checking the formal derivation submitted in this article is not a difficult task. With respect to proper theoretical physics, the formal inference is a nontrivial scientific novelty which has not been discussed and published elsewhere yet.
文摘Based on the governing equations of the inner cyinder of the unsteady flow of the power law fluid in eccentric annuli with the inner cylinder reciprocating axially in bipolar coordinate system, the calculation formulae of tangential force were established, and the relevant numerical calculation method was given. Taking the aqueous solution of partially hydrolyzed polyacrylamides (HPAM) for examples, the tangential forces were calculated by using the formulae and numerical calculation method mentioned above;the curves of the tangential force on the wall of the inner cylinder of HPAM aqueous solution were plotted;and the effects on the tangential force of the flow behavior index of the power law fluid, the stroke and the stroke frequency of the inner cylinder were analyzed.

文摘The Chinese government is dedicated to enhancing the level of informatization in administrative law enforcement to ensure fairness and increase credibility.Currently,law enforcement has exposed such problems as insufficient force,difficulties in collecting evidence,and low evidential power.These problems contradict the principles of rule of law and standardization.Many local governments have implemented advanced information technologies for urban administration and law enforcement,including big data,artificial intelligence,and IoT.Among these technologies,IoT is the core communication infrastructure for innovative law enforcement platforms.However,traditional video communications rely on batteries or dedicated power sources,leading to maintenance challenges and high power consumption.In this paper,we propose AT-Eye,a new video communication paradigm for all-time law enforcement video monitoring,which is battery-free and high-throughput.The key enabler of AT-Eye is ambient backscatter technology,which enables energy harvesting and video communication simultaneously.Unlike previous methods,our proposal introduces a novel CCK-based modulation for tag cameras and achieves 4-way concurrency.The modulation is simple because it uses phase difference and it is energyefficient because generating square waves is adequate.Moreover,to ensure full compatibility with COTS WiFi,we modulate the physical service data unit.Therefore,data recovery is possible using only commercial NICs.We conduct comprehensive experiments to examine our proposal and experiment results show that AT-Eye achieves a throughput of 10.8 Mbps with COTS radios.We also simulate a 16-way battery-free tag camera system,demonstrating AT-Eye’s feasibility of high-definition video communication.

文摘Kenya like most of sub-Saharan Africa is reliant predominantly on agriculture and natural resources;which include land, water, minerals and fisheries, but the most dominant of which </span></span><span><span><span>are</span></span></span><span><span><span> wildlife and forestry. Unlike minerals which are by law vested in the government and can only be extracted by it and not the citizenry, wildlife and forestry are resources that the citizens may utilize in their day to day lives to meet their needs. Apart from their consumptive uses, there are also non-consumptive uses and values of wild animals and forests;such as their intrinsic ecological value as gene banks, as well as their scenic value for viewing. These are essentially conventional values and uses. They are largely formal and universal ones that are universally obtaining across </span></span></span><span><span><span>the </span></span></span><span><span><span>world irrespective of the levels of civilization or cultural identity, and </span></span></span><span><span><span>are </span></span></span><span><span><span>even compatible with modernity. Apart from these, there are some wildlife and forestry uses </span></span></span><span><span><span>which</span></span></span><span><span><span> </span></span></span><span><span><span>are </span></span></span><span><span><span>unique to the typical African way of life as part of old traditional customs that have existed from earlier times. These are what are in this paper referred to as “traditional customary uses”. These uses are largely informal, rudimentary and archaic. They are nevertheless critical in the endemic African way of life and represent the inextricable rudimentary technologically bereft relationship between the African people and their natural resources. Under the country’s existing laws, some of these uses are prohibited and criminal sanctions prescribed to enforce their proscription, hence cannot be enjoyed or practiced. There are however others that the law</span></span></span><span><span><span> has</span></span></span><span><span><span> either expressly allowed, or not prohibited, hence may be lawfully enjoyed or practiced. These are what this paper has referred to as the legally permissible traditional customary uses;and are the ones that are its subject. As for wildlife, in the year 1977, the Kenya Government by a Legal Notice in the Kenya Gazette imposed a ban on all forms of hunting of wildlife. </span></span></span><span><span><span>The ban is still in force</span></span></span><span><span><span>. This therefore means that hunting is illegal, as legal prohibition has in effect prohibited all and any form of off-take or killing of wildlife. By implication therefore, under Kenyan law, only non-consumptive uses of wildlife may be enjoyed, and not the consumptive ones. These include viewing as well as socio-cultural and spiritual uses</span></span></span><span><span><span>.</span></span></span><span><span><span> In Kenya therefore, the only permissible traditional customary use of wildlife is its non-consumptive use for socio-cultural and spiritual purposes;subject of course to the existing legal prohibition on witchcraft under the Witchcraft Act</span></span></span><span><span><span> <span style="color:#943634;">(</span></span></span></span><span><span><span><a href="#ref53">Cap 67 Laws of Kenya</a></span></span></span><a href="file:///C:/Users/test.scirp/Desktop/%E6%96%B0%E5%BB%BA%20Microsoft%20Word%20%E6%96%87%E6%A1%A3.docx#R53"><span><span></span></span></a><span><span><span>)</span></span></span><span><span><span>. This piece of legislation has prohibited the practice and promotion</span></span></span><span><span><span> </span></span></span><span><span><span><span>of witchcra</span><span>ft. This in effect means that the socio-cultural and spiritual uses of wildlife though legally permissible, will be enjoyed, provided it is not for witchcraft purposes. With regard to forests, this author has identified the following five as their legally permissible traditional customary uses under Kenyan law: Socio-cultural and spiritual (consumptive and non-consumptive)</span><span> use, other than for witchcraft;use in herbal folk medicine, other than for witchcraft;use for human food and livestock fodder;use for firewood;and use as raw material in construction and traditional craft. Notably, in Kenya, traditional customary use is subject to the existing legal prohibition on witchcraft. Further, while it is the legally permissible use category that is the focus of this paper, the author nevertheless discusses the prohibited traditional customary uses as well. This paper is based on literature survey as well as data obtained from the author’s previous research whose primary data and findings have been published in recent times. It also draws from the documented research and diverse documented views of other commentators on the subject.
文摘This is the first paper in a two part series on black holes. In this work, we concern ourselves with the event horizon. A second follow-up paper will deal with its internal structure. We hypothesize that black holes are 4-dimensional spatial, steady state, self-contained spheres filled with black-body radiation. As such, the event horizon marks the boundary between two adjacent spaces, 4-D and 3-D, and there, we consider the radiative transfers involving black- body photons. We generalize the Stefan-Boltzmann law assuming that photons can transition between different dimensional spaces, and we can show how for a 3-D/4-D interface, one can only have zero, or net positive, transfer of radiative energy into the black hole. We find that we can predict the temperature just inside the event horizon, on the 4-D side, given the mass, or radius, of the black hole. For an isolated black hole with no radiative heat inflow, we will assume that the temperature, on the outside, is the CMB temperature, T2 = 2.725 K. We take into account the full complement of radiative energy, which for a black body will consist of internal energy density, radiative pressure, and entropy density. It is specifically the entropy density which is responsible for the heat flowing in. We also generalize the Young- Laplace equation for a 4-D/3-D interface. We derive an expression for the surface tension, and prove that it is necessarily positive, and finite, for a 4-D/3-D membrane. This is important as it will lead to an inherently positively curved object, which a black hole is. With this surface tension, we can determine the work needed to expand the black hole. We give two formulations, one involving the surface tension directly, and the other involving the coefficient of surface tension. Because two surfaces are expanding, the 4-D and the 3-D surfaces, there are two radiative contributions to the work done, one positive, which assists expansion. The other is negative, which will resist an increase in volume. The 4-D side promotes expansion whereas the 3-D side hinders it. At the surface itself, we also have gravity, which is the major contribution to the finite surface tension in almost all situations, which we calculate in the second paper. The surface tension depends not only on the size, or mass, of the black hole, but also on the outside surface temperature, quantities which are accessible observationally. Outside surface temperature will also determine inflow. Finally, we develop a “waterfall model” for a black hole, based on what happens at the event horizon. There we find a sharp discontinuity in temperature upon entering the event horizon, from the 3-D side. This is due to the increased surface area in 4-D space, AR(4) = 2π2R3, versus the 3-D surface area, AR(3) = 4πR2. This leads to much reduced radiative pressures, internal energy densities, and total energy densities just inside the event horizon. All quantities are explicitly calculated in terms of the outside surface temperature, and size of a black hole. Any net radiative heat inflow into the black hole, if it is non-zero, is restricted by the condition that, 0cdQ/dt FR(3), where, FR(3), is the 3-D radiative force applied to the event horizon, pushing it in. We argue throughout this paper that a 3-D/3-D interface would not have the same desirable characteristics as a 4-D/3-D interface. This includes allowing for only zero or net positive heat inflow into the black hole, an inherently positive finite radiative surface tension, much reduced temperatures just inside the event horizon, and limits on inflow.
文摘Since the Qin Dynasty started the county system to the foundation of China, "county" has been the basic unit of the centralized state in our country. Although the county-level governance mode is stable, its evolution has laws to follow. Generally speaking, the rules are that the scale of the county government is small for a long time and the governmental functions in the long term are fixed. The roles of the clan organizations in the social governance are increasingly strengthened and the slow development and roles of other social organizations outside the clan organizations are increasing.
文摘Waters off the coasts of West Africa are very rich with many different types of fish and marine life.Some species like sardines,tuna,mackerel,tilapia and shrimps are important to many local communities and economies in West Africa.However,the current overfishing of these fish affects the sustainability of fishery industry.Despite Ghana ratifying to a number of international marine laws to ensure a sustainable marine fishing,there seem to be some challenges that are associated with marine fishing in Ghana.This paper further examines the strategies that have been employed by the fishing community and the fisheries ministry in Ghana as a response to restrictive measures for the challenges identified and discussed in literature.This paper is fundamentally an extensive review of marine fisheries literature.In general terms,it was found that,Ghana has ratified to a number of international marine laws including the UNCLOS.
