It is evident from Table 1 that most ofthe applied morphological varia- bles did not deviate considerably from the normal distribution. Exceptions were registered for the measures of skin fold ofthe back (Sk = 1.23), skin fold ofthe abdomen (Sk = 1.67) and pelvis breadth (Sk = 1.23) whose positive me- asures of asymmetry showed that the young karatists had a somewhat wider pelvis and an increased amount of subcutaneous fatty tissue. Distribution cur- ves of all variables were either mesokurtic or platykurtic, except those for the skin fold ofthe back (Ku = 6.58) and pelvis breadth (Ku = 5.39) which were leptokurtic.
Presented paper contains evaluation of influence of selected parameters on sensitivity of a numerical model of solidification. The investigated model is based onthe heat conduction equation with a heat source and solved using the finite element method (FEM). The model is built with the use of enthalpy formulation for solidification and using an intermediate solid fraction growth model. The model sensitivity is studied with the use of Morris method, which is one of global sensitivity methods. Characteristic feature ofthe global methods is necessity to conduct a series of simulations applying the investigated model with appropriately chosen model parameters. The advantage of Morris method is possibility to reduce the number of necessary simulations. Results ofthe presented work allow to answer the question how generic sensitivity analysis results are, particularly if sensitivity analysis results depend only on model characteristics and not on things such as density ofthe finite element mesh or shape ofthe region. Results of this research allow to conclude that sensitivity analysis with use of Morris method depends only on characteristic ofthe investigated model.
Abstract: The study examined the male and female level of access and ownership to land for cassava production in Abia state. The objectives ofthe study were to describe the socio-economic characteristics ofthe respondents, determine the differences in quantity of cassava produced by both male and female farmers. A multi-stage random sampling technique was used select 218 respondents. Questionnaire was used for data collection while frequency counts, mean, percentages and Z-test were used in analyzing the data generated. The result shows that the mean age for male and the female were 52.7 and 46.2 years respectively. 94.5% ofthe male and 97.2% ofthe female had one form of formal education. The mean household size ofthe male and the female were 8 and 7 persons per house. The mean farming experiences ofthe male and female were 16.54 years and 13.26 years respectively. Mean income generated from cassava stand to be (#) 54882.57 and (#) 126082.60 respectively for both male and female. The Z- test analysis result shows that mean farm sizes ofthe respondents were 2.91 hectares and 2.45 hectares respectively for both male and female. Theanalysis also showed that there was significant difference between access to farmland of male and the female farmers at t = -2.613 at 5% significant level and cassava output of male and the female at t = -4.764 at 1% significant level. It was therefore recommended that a micro- credit scheme be established by government and nongovernmental organization target mainly on female cassava farmers for purchase of resources for cassava production.
Focusing onthe social management recommended by the 1978 Conference of Alma-Ata, the present study aimed to reflect on how Italian family doctors experienced the relationship between health and societies in the experience of their practices. A field study with a qualitative approach and exploratory-descriptive nature, carried out) in 2007, in the province of Rome, Italy, with Italian family doctors. Performed according to the perspective of everyday bioethics, theanalysis revealed that theanthropological-social dimension in the experience ofthe Italian family medical practice depends onthe context in which such practice occurs, and that (risk) social risk management, in the individual sphere, is a common constitutive aspect. It could be concluded that, when dealing with the relationship between health and societies, from a moral dimension towards an ethical practice, it sets the possibility of fulfilling the ideal of making Primary Health Care the center of national health systems..
contains aggregate prices and quantities for all the US regional markets from the US Geological Survey’s Mineral Yearbook. The other contains the capacities of plants and plant-level information that Ryan has collected for the Portland cement industry in the United States from 1980 to 1998. Data on plants includes the name ofthe …rm that owns the plant, the location ofthe plant, the number of kilns in the plant and kiln characteristics. Following Ryan we assume that the plant capacity equals the sum ofthe capacity of all kilns in the plant and that di¤erent plants are owned by di¤erent …rms. We observe that plants’ names and ownerships change frequently. This can be due to either mergers and acquisitions or to simple changes in the company name. We do not treat these changes as entry/exit movements. We check each observation in the sample using the kiln information (fuel type, process type, year of installation and plant location) installed in the plant. If a plant changes its name but keeps the same kiln characteristics, we assume that the name change is not associated to any entry/exit movement. This way of preparing the data enables us to match most ofthe summary statistics of plant-level data in Table 2 of Ryan. Any discrepancies most likely can be attributed to the way we treat the change in plants’ names, which may di¤er to Ryan in a
In the quality assurance system for components cast using the lost wax method, the object of evaluation is the grain size onthe surface ofthe casting. This paper describes a new method for evaluating the primary grain parameters onthe surface of aircraft engine turbine blades. Effectiveness ofthe method has been tested on two macrostructures distinguished by a high degree of diversity in the grain size. The grounds for evaluating the grain parameters consist of geometric measurement ofthe turbine blade using a laser profilometer and of approximation ofthe measurement results using a polynomial of a proper degree. The so obtained analytical non-planar surface serves as a reference point for an assessment ofthe parameters of grains observed onthe real blade surface of a variable curvature. The aspects subjected to evaluation included: the grain areas, shape and elongation coefficients of grains on a non-planar surface ofthe blade airfoil, using measurements taken on a perpendicular projection by means of a stereoscopic microscope and image analysis methods, and by making calculations using the Mathematica ® package.
The paper presents a statistical assessment ofthe effect of chemical composition on mechanical properties of hypereutectic AlSi17 silumin, which is expected to act as a counterpart of alloys used by automotive industry and aviation for casting of high-duty engine parts in West European countries and USA. The studies onthe choice of chemical composition of silumins were preceded by analysisofthe reference literature to state what effect some selected alloying elements and manufacturing technology may have onthe mechanical properties (HB, R m and A 5 ) of these alloys. As alloying additives, Cu, Ni and Mg in proper combinations were used. The alloy after
An analysisofthe current state of knowledge indicates that the microstructure hypoeutectoid aluminum bronze with additions of Fe, Ni, Si and Mn, at ambient temperature, may be present a lot of hard intermetallic phases of κ type [1÷3]. Characteristic of these phases is that they contain except to Ni, elements with low solubility in solutions of β and α, characteristic for the matrix aluminum bronze. Table 1 shows the types of κ phase identified in the aluminum bronzes and concentration of their constituent elements. It is possible to distinguish two groups generally, the first group is rich intermetallic phases mainly Fe ( κ Fe , κ I , κ II and
In theAnalysis Section, three articles deal with the institutionalization ofthe sciences and scientific professionalization within the Brazilian context in its decisive era, situated more or less between the creation (late) ofthe university, in the 1930s, and the first great reform ofthe university system, at the end ofthe 1960s. This is not mere coincidence. One ofthe singular aspects (and least studied) ofthe ‘formation ofthe scientific community’ in Brazil is its insertion in the broad process of social and cultural changes that had as a consequence, among others, the restructuring ofthe gender system. It becomes transparent in theanalysisofthe role of Marina de Vasconcellos in the foundation ofthe Brazilian anthropological tradition, in the superimposition ofthe public image of Bertha Lutz, at once a militant feminist and a scientific professional, and in the dynamics of gender manifested in the scientific production of that period.
Abstract: The primary objective ofthe project is to create a prototype of a purely air powered motorcycle by retrofitting its internal combustion engine to run on compressed air. Firstly, the conventional spark plug was replaced with a solenoid valve. The solenoid valve was initially actuated using a reed switch and magnet duo, but then later replaced with an optical crank position sensor circuit due to reasons that include lack of control over the amount of air injected during each stroke and also for more precise control over the opening and closing ofthe valve. The torque, brake power, indicated power, air consumption rate ofthe engine under load are calculated. Separate mounts for the modified engine and the cylindrical storage unit are designed and analysed using Catia v4. Also, possible ways of future scope ofthe prototype are mentioned.
The era of globalization is impact onthe necessity for each country to be able to compete with the world competition that tends indefinitely. It is synonymous with the concept of state sovereignty reduction, technological sophistication, and world space narrowing and trade transactions development as a thinking the implementation of free trade. Globalization has had an impact onthe escalation ofthe nation‘s defense and security threats in border region. As awareness for the perception of border region between countries to encourage policy makers to develop an assessment about the arrangement of border region equipped with the formulation of security system. As an archipelagic country, Indonesia has more than 17.504. islands with a coastline of more than 80.290 km, and borders with 10 neighboring countries. On land areas, Indonesia borders with 3 (three) countries, i.e Malaysia, Papua Nugini and Timor Leste, while on sea areas, border with 10 (ten) countries, i.e India, Thailand, Malaysia, Singapore, Vietnam, Philippines, Palau, Papua Nugini, Australia and Timor Leste. The area of this border has strategic value, in both aspects of defense and security; the border region is the territorial limits ofthe Republic of Indonesia are very influential on national‘s defense and security.
There is a detail that could be difficult to deal with: because ofthe interplanetary distances the dialogue between the two culture wouldn't certainly be prompt. It would be necessary to plan message exchanges knowing that the answers may arrive to next generations. In this scenario, the correction of a possible initial misunderstanding would be expensive, in terms of time. More, we have to be prepared to the plausible hypothesis that the extraterrestrial intelligence which we are trying to start a connection with has a different psychology, given by different physiology, whereas the interpretation of cultures provided by anthropology is often based onthe fact that the representatives ofthe different cultures belong to the same species. However there are studies aimed to understand how to connect with different species, by the paleoanthropological and archaeological reconstruction ofthe life and relationships ofthe hominid species which came before us. In particular, however difficult it may be to consider in all its aspects, a precious help can come from the encounter between the Homo sapiens and the Homo neanderthalensis, which anatomical and cultural differences would have caused remarkable difficulties to both species, even though they both belonged to the Homo family. These differences come out, for instance, in the organization ofthe Mousterian sites, much simpler than the sites occupied by the Homo sapiens, which in general look more structured and divided by areas of utilization (Wason, 2011).
the peritectic transformation during the last stage of solidification, proceeding in fact under the non-equilibrium conditions. The negative influence ofthe effects ofthe peritectic transformation during the solidification of carbon steels, particularly those cast with use ofthe CSC technology, is well- known and results in the increased quantity of defects [5-9]. The verification – based ontheanalysisofthe duplex type cast steel solidification – if it is reasonable to speak about a peritectic transformation in relation to GX2CrNiMoCuN25-6-3-3 cast steel has been recognized as important. Chemical compositions of ferritic-austenitic cast steel grades given by the PN-EN 10283:2004 Standard provide for ferritic solidification. It is confirmed by the data calculated according the formulae shown in Table 1 .
Mixing processes involve the blending of silica sand, bentonite, coal dust (or mixture) and water. The purpose of mixing is to homogenise the mixture and ensure that the rebonding agent should be uniformly distributed over the grains. This unit was designed for separating casts from the runner system. the number of casts in a batch ranges from 1 to 4 onthe given level, there are 1-48 of them on 1-12 levels. The mass ofthe batch varies from 5 to 12 kg.
Dermerwean,  describes that Lean Accounting refers to attempts to derive monetary management information based on Lean principles. . In Lean manufacturing absolutly need lean accounting as control in the enterprise. According to Aghdaei ,  said that Lean accounting is looking forward decreasing the stages in implementation process and omitting the standard prices for achieving real prices and inhibiting expense allotments, whereas lean control operations are still considering measurement of system performance and emphasize on social and behavioral controls. Dermerwean,  also said that Lean refers to the management system of applying Lean principles to operations, and Lean Accounting refers to attempts to derive monetary management information based on Lean principles. Maskell,  give statement that Lean accounting focuses on measuring and understanding the value created for the customers, and uses this information to enhance customer relationships, product design, product pricing, and lean improvement.. Based on statement above lean accounting have some function to improvement all aspect about costumers and product. Management accounting information it provides with use one-touch flow design as lean accounting refer to lean operational principle, lean accounting also has alternative to traditional management system. ,. In the company has principle of lean thinking to grow their company use lean accounting. Rosa  said that lean accounting is a new accounting approach stemming from the growing interest of companies in embracing the culture of lean thinking.  There’re new method to increase a companies. Every companies must to use good method one of such lean accounting to control financial. Womack, describes that lean accounting, more that a new method, is the adaptation of familiar financial and management accounting methods to the needs of lean organizations, with the aims of : providing information to motivate lean transformation; eliminating waste from the accounting processes while maintaining financial
Theanalysis was carried out concerning the data gathered in Tables 4-7 and photographs presenting both the shape, the magnitude, and the distribution of graphite precipitates (Figs 1, 3, 5, 7), as well as those showing the microstucture of cast iron (Figs 2, 4, 6, 8). It allowed for the assessment ofthe influence of aluminium added in the quantity falling into the concerned range on both the graphitization of cast iron and its susceptibility to spheroidization with cerium mischmetal. The latter addition was used in the quantity of 0.11 wt% ofthe material subjected to the treatment.
of households are expected to continue to perform their traditional roles and at the same time take on men’s responsibilities. However, culture dictates that they consult men even when they are away. The daunting extra burden on rural women left behind can have far-reaching consequences, including on girls. Girls are stopped from going to school and take up the roles of their mother when their fathers have migrated to town, hence, denying them education. This study is in concurrence, with a study done in China, which found out that the shortage of male farm workers due to migration has resulted in girls being pulled out of school in order to take care of younger siblings and to help with farm work (IOM, 2009). Further analysisofthe literature review indicates that in African societies, decisions about rural development projects are usually hampered by absenteeism of men in the household and they are the determinants on women’s involvement in community projects. This paper observes that women’s needs frequently differ from those of men, but are often overlooked when such kind of projects are being formulated and implemented. Therefore, improved access to decision making would provide women a chance to articulate their peculiar needs in the household and the community. Implications on Education
Intermetals are creep-resistant materials with unique properties intermediate between the properties of metals and ceramics. Their low density, high strength and resistance to oxidation, combined with sufficient ductility and fracture toughness, make them an attractive material for machine elements operating at elevated temperatures and in corrosive environments. Intermetallic phases based on Fe and Al (called intermetallics) are intermetallic compounds very interesting in terms ofthe technological properties, which combine the properties of metals and ceramics. From the Fe-Al phase equilibrium diagram it follows that the widest use could have two phases: FeAl and Fe 3 Al. Of these two phases, more useful seems be the FeAl
