description: We investigated the thermoelectric transport properties of EuNi2P2 and EuIr2Si2 in order to evaluate the relevance of Kondo interaction and valence fluctuations in these materials. While the thermal conductivities behave conventionally, the thermopower curves exhibit large values with pronounced maxima as typically observed in Ce- and Yb-based heavy-fermion materials. However, neither the positions of these maxima nor the absolute thermopower values at low temperature are in line with the heavy-fermion scenario and the moderately enhanced effective charge carrier masses. Instead, we may relate the thermopower in our materials to the temperature-dependent Eu valence by taking into account changes in the chemical potential. Our analysis confirms that valence fluctuations play an important role in EuNi2P2 and EuIr2Si2.

description: In 1983-84, less than 1% of cattle in Bangladesh were of improved variety in spite of the fact that efforts to improve cattle through cross-breeding and grading were started by the British in the middle of the previous century. This paper analyses the research and policy shortcomings of the cattle breeding programmes that led to this situation. A particular emphasis is on the effects of use of cows for draft purposes as empirical evidence shows that draft use of cows have negative effects on milk yield and fertility. The argument is supported by field data based on a sample of farm cattle from several districts.

description: This paper reports the findings of an investigation into the extent, underlying causes, and effects of biomass fuel shortages in four Bangladesh villages. Shortages are found everywhere, and are becoming more severe; but the problem is particularly pronounced in pert-urban locations. The landless have been affected much more seriously than other classes, and the implications for landless women are particularly unfavourable. This situation derives from the combined effects of unequal access to resources and rapidly increasing population within the rural areas. Increasing demand for biomass products from industrial and urban consumers has also played an important part. A number of possible solutions are explored. These include: increasing the supply of biomass fuels; improving the efficency with which they are converted; the introduction of substitutes; and the creation of additional sources of income for those most in need.

description: We present several coupled-cluster calculations of ground and excited states of 4He and 16O employing methods from quantum chemistry. A comparison of coupled cluster results with the results of exact diagonalization of the hamiltonian in the same model space and other truncated shell-model calculations shows that the quantum chemistry inspired coupled cluster approximations provide an excellent description of ground and excited states of nuclei, with much less computational effort than traditional large-scale shell-model approaches. Unless truncations are made, for nuclei like 16O, full-fledged shell-model calculations with four or more major shells are not possible. However, these and even larger systems can be studied with the coupled cluster methods due to the polynomial rather than factorial scaling inherent in standard shell-model studies. This makes the coupled cluster approaches, developed in quantum chemistry, viable methods for describing weakly bound systems of interest for future nuclear facilities.

description: We present a machine vision-based database named GrainSet for the purpose of visual quality inspection of grain kernels. The database contains more than 350K single-kernel images with experts' annotations. The grain kernels used in the study consist of four types of cereal grains including wheat, maize, sorghum and rice, and were collected from over 20 regions in 5 countries. The surface information of each kernel is captured by our custom-built device equipped with high-resolution optic sensor units, and corresponding sampling information and annotations include collection location and time, morphology, physical size, weight, and Damage & Unsound grain categories provided by senior inspectors. In addition, we employed a commonly used deep learning model to provide classification results as a benchmark. We believe that our GrainSet will facilitate future research in fields such as assisting inspectors in grain quality inspections, providing guidance for grain storage and trade, and contributing to applications of smart agriculture.

description: Booster seat use among the general population remains relatively low, despite their effectiveness in preventing injury among children when involved in motor vehicle collisions. Given the prevention of injuries that booster seats provide, understanding the factors that hinder or facilitate the use of these seats is critical, particularly in communities that are often overlooked when conducting general population studies. To date, no studies have examined the prevalence and predictors of booster seat use among Indigenous peoples in Canada. The purpose of this study was to examine the use of booster seat use among Indigenous peoples across Canada and the factors that impact their use. Data were collected from a survey of participants from First Nations communities and organizations serving Indigenous peoples nationwide. Hypotheses arising from known predictors of booster seat use across the general population were tested using logistic regression models. The strongest predictor of booster seat use, even when all other study factors were accounted for, was the reduction of barriers related to the use of booster seats, such as a child’s resistance to being placed or staying in the passive safety restraint or a parent, guardian, or other caregiver being unwilling to use or unsure of how to install/setup the booster seat. Most Indigenous participants consistently used booster seats to safely secure children being transported in vehicles. However, this compliance rate is well below that of the general population. Accessibility and affordability of child safety restraints and/or children’s refusal to use booster seats, as well as having more than 1 child to secure, were identified as mitigating factors. Access to and the affordability of booster seats, coupled with clear and understandable information on how to use them, are critical components to compliance. Raising awareness among Indigenous peoples communities regarding the importance of using booster seats is imperative. To achieve this, Indigenous peoples must lead discussions to ensure that child safety strategies not only are based on research and best practices but are culturally connected and community driven. Through meaningful collaboration, vehicle-related injuries and mortality among Indigenous children can be significantly reduced.

description: The major objectives of the study weree (a) to assess the farm equipment innovations generated by local R & D system and their commercialization; (b) to investigate sources of design of prototypes and appropriateness to farmer needs and local conditions; (c) to assess the collaborative linkages among R & D institutes, financial bodies, marketing agencies and farming community in the commercialization and dissemination of prototypes; and (d) to identify the form and mechanisms of and constraints to commercialization of prototypes. All the major formal R & D institutions concerned with work on-farm equipment were closely studied. Five major manufacturing firms which make a significant contribution to adaptation and upgrading of farm equipment technology were also examined in depth. In addition, 30 farm equipment manufacturing firms and a sample of 100 farm households were included in the survey. The most startling conclusion is that not a single prototype developed by the formal R & D institutions of Bangladesh has been commercialized. In contrast 20 prototypes developed by the private firms are being commercially manufactured. A number of factors which affect commercialization of prototypes generated by all R & D institutions in general and formal R & D bodies in particular, have been identified. The private manufacturing sector R & D has been more successful in commercializing their prototypes because they were more responsive to farmer needs and local conditions at the R & D stage. As a result market demand for the new product was not a constraint. The formal R & D system is handicapped by lack of institutionalized mechanisms for marketing and commercialization of their prototypes and the deprivation of the inventor in the formal R & D system of patency rights has acted as a disincentive to its commercialization. Conflicting government aid and commercial policies in the direct import of finished products have either made R & D efforts in certain agricultural equipment unprofitable or contributed to excess capacity in the manufacturing sector. The commercialization of prototypes generated by the formal R & D system is further hindered by lack of inter-disciplinary approaches and absence of coordination among R & D institutions (leading to duplication) and lack of collaborative linkages among R and D institutions, marketing agencies, financial institutions and the faming community.

description: In this talk I will discuss the role of finite temperature quantum corrections in string cosmology and show that they can lead to a stabilization mechanism for the volume moduli. I will show that from the higher dimensional perspective this results from the effect of states of enhanced symmetry on the one-loop free energy. These states lead not only to stabilization, but also suggest an alternative model for cold dark matter. At late times, when the low energy effective field theory gives the appropriate description of the dynamics, the moduli will begin to slow-roll and stabilization will generically fail. However, stabilization can be recovered by considering cosmological particle production near the points of enhanced symmetry leading to the process known as moduli trapping.

description: Strong-field photoelectron momentum imaging of the prototypical biomolecule indole was disentangled in a combined experimental and computational approach. Experimentally, strong control over the molecules enabled the acquisition of photoelectron momentum distributions in the molecular frame for a well-defined, narrow range of incident intensities. A novel, highly efficient semiclassical simulation setup based on the adiabatic tunneling theory quantitatively reproduced these results. Jointly, experiment and computations revealed holographic structures in the asymptotic momentum distributions, which were found to sensitively depend on the alignment of the molecular frame. We identified the essential molecular properties that shape the photoelectron wavepacket in the first step of the ionization process and employ a quantum-chemically exact description of the cation during the subsequent continuum dynamics. The detailed modeling of the molecular ion, which accounts for its polarization by the laser-electric field, enables the simulation of laser-induced electron diffraction off large and complex molecules and provides full insight into the photoelectron's dynamics in terms of semiclassical trajectories. This provides the computational means to unravel strong-field diffractive imaging of biomolecular systems on femtosecond time scales.

description: Students will learn about the Mexican Revolution, specifically about the role class and gender played during this time period, through a four-day unit consisting of three lessons and a final day summative activity. The unit will begin with a broad overview of the major historical events, people, and locations that define this period of Mexican history. The second lesson will focus on prescribed gender roles (combatants, mothers, community leaders, and military support) and stereotypes of women in Mexican society, and what women were doing during the Mexican Revolution to challenge these. The third and final lesson of the unit will explore the role of socioeconomic class as an additional perspective in which we can view how women behaved and participated in the Mexican Revolution. The unit will end with a summative assessment in which students will work in groups to create their own “penny press” publication that includes short articles and visual depictions of the major issues discussed in the unit.

description: Gaetano Mosca dedicated much of his life’s work to his theory of the ruling class, developing it in numerous publications. Despite his long meditation on the subject and subsequent revisions, however, Mosca never provided a systematic, properly articulated expose’ of his doctrine, in which the various components were logically arranged and examined from all points of view. The present article gathers together the scattered parts of Mosca’s theories into an organic whole, giving the reader an immediate and fairly precise idea of both the complexity of the research as well as the unfinished state in which the author left it. The author draws freely upon passages from Mosca’s various works in order to illustrate the following aspects of the ruling class: composition and formation; extension; renewal and replacement; organisation and means of exercising power.

Total synthesis of streptonigrone
Creators: name: Chan, Bryan Ka Ip
Publisher: name: University of British Columbia
Year: 2011

description: This thesis describes the total synthesis of streptonigrone. The centerpiece of our route to the target molecule is a facile one-pot construction of 3-alkylpyridones developed in our laboratory. The quinoline segment of the target molecule, prepared through a Conrad-Limpach synthesis, was condensed with 2-benzyloxy-3,4-dimethoxybenzaldehyde to afford a chalcone intermediate suitable for our pyridine-forming reaction. The assembly of the central 3-methylpyridone ring of the natural product was then accomplished through the merger of the chalcone with 2-cyanopropanamide. Functionalization of the pyridone was then completed through an anionic sequence.

description: Field data based evidence presented in this study suggested that for measuring relative efficiency of different groups of farms, tenurial classification was more appropriate than size classification on the basis of land or any other singly input category. It was found that different tenure classes achieved different levels of efficiency but owner-operators were the most efficient. That means, taken as a whole, the farms did not achieve optimum level of efficiency in using resources from the point of view of the society. Relative inefficiency of tenure classes involving sharecropping (part-operators, part-tenants and tenants) implies that the existing pattern of resource ownership and property relations are improper for attaining higher level of efficiency. Development policy implies government policy. Since objectives and methods of governments differ according to ideologies, specific policy actions could not be recommended on the basis of the findings of this study. However, the findings indicated that any government with a genuine desire to develop the agricultural sector should initiate an agrarian reform programme by correcting the present maldistribution of land, labour and capital resources and by reorganizing the government institutions serving agriculture.

Studies of some technologically important interfaces
Creators: name: Teo, Mark Yu Chao
Publisher: name: University of British Columbia
Year: 2011

description: This thesis discusses surface and interfacial investigations for two technologically important areas. The first area focuses on surface modification of oxidized high-purity aluminum for improved interfacial bonding with an organosilane, bis-1,2-(triethoxysilyl)ethane (BTSE), for adhesion promotion and corrosion protection. BTSE adsorption onto various pre-treated oxidized aluminum surfaces are compared. Secondary ion mass spectroscopy (SIMS), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) were used to assess the effects of pre-treatment on the direct Al-O-Si covalent bonding and the strength of adhesive bonding. Applying a sulphuric-chromic (FPL--Forest Products Laboratory) pre-treatment to native oxide on high-purity Al generates a compact, well-anchored oxide layer with a surface that is effective for Al-O-Si bonding after BTSE coating. H₂ plasma pre-treatments improve BTSE chemisorption on FPL pre-treated Al surfaces. However, heat pre-treatments can modify a native Al oxide surface for increased adhesion with BTSE. The second area focuses on the use of transition metal chalcogen thin films and powders in oxygen reduction reaction (ORR) catalysis for proton exchange membrane (PEM) fuel cells. A novel combination of micro-Raman spectroscopy and scanning Auger microscopy (SAM) enabled the identification of different elemental compositions at local regions of a Co-Se thin film which led to a reinterpretation of Raman peaks reported previously. Raman characterization of sputtered Fe-S, Co-S and Ni-S thin film surfaces identified the respective disulfide structures and suggested the presence of polysulfides (Sn²⁻) which may contribute to an improved ORR catalytic activity when compared to the corresponding disulfide standard. A sputtered Co-Ni-S thin film containing (Co,Ni)S₂ solid solution with possible polysulfides showed an enhanced ORR catalytic activity compared with other samples. A method for synthesizing high-purity, crystalline CoSe₂ powder on high-area carbon support is established; its surface and bulk structures are confirmed by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), micro-Raman spectroscopy, XPS and SAM. CoSe₂ demonstrated significant ORR catalytic activity with an OCP of 0.81 V and higher current density than CoSe. CoSe₂, characterized by combining SAM and backscattered electron (BSE) imaging, was electrochemically modified via cyclic voltammetry to give a Se-rich surface to enhance its ORR catalytic activity.
Is Double Reionization Physically Plausible?

description: Recent observations of z~6 quasars and the cosmic microwave background imply a complex history to cosmic reionization. Such a history requires some form of feedback to extend reionization over a long time interval, but the nature of the feedback and how rapidly it operates remain highly uncertain. Here we focus on one aspect of this complexity: which physical processes can cause the global ionized fraction to evolve non-monotonically with cosmic time? We consider a range of mechanisms and conclude that double reionization is much less likely than a long, but still monotonic, ionization history. We first examine how galactic winds affect the transition from metal-free to normal star formation. Because the transition is actually spatially inhomogeneous and temporally extended, this mechanism cannot be responsible for double reionization given plausible parameters for the winds. We next consider photoheating, which causes the cosmological Jeans mass to increase in ionized regions and hence suppresses galaxy formation there. In this case, double reionization requires that small halos form stars efficiently, that the suppression from photoheating is strong relative to current expectations, and that ionizing photons are preferentially produced outside of previously ionized regions. Finally, we consider H_2 photodissociation, in which the buildup of a soft ultraviolet background suppresses star formation in small halos. This can in principle cause the ionized fraction to temporarily decrease, but only during the earliest stages of reionization. Finally, we briefly consider the effects of some of these feedback mechanisms on the topology of reionization.

description: The problem of treating management as an explanatory variable in agricultural production function has not yet been solved satisfactorily mainly because of the lack of a generally accepted cardinal measure. Only a few agricultural production function analyses are known to have included management as an explanatory variable. These investigations have specified management in different ways under a diversity of assumptions and obtained different kinds of results even with comparable situations. The objective of this article is to present a critical review of the theoretical meaning of management and of the effectiveness of different ways of treating management in empirical investigations.

description: In 1972, the Bangladesh government ordered all farm families owning more than 33.3 acres of land to surrender the excess land for redistribution among families owning less than 1.5 acres of land. The basis of choosing these figures are not known. Since there are very few farms above the declared maximum size, the redistributive effect of these measures are not likely to be more than marginal. In a sample of 300 farms in three districts – Mymensingh, Rangpur, Dinajpur- major maladjustment existed between land and labour: some farms owned more land per unit of available labour than they could cultivate themselves thereby opening the way for making sharecropping arrangements; others owned less land per man-unit than was necessary to provide full employment.The need for land redistribution arose because of the necessity to alleviate the adverse effects of this maladjustment on production efficiency, income distribution and technological improvement. In this study, linear programming was a applied to determine optimal and minimum size of farms in the given situation to promote owner-operated farms to improve production efficiency, and maximize family labour use under different technological assumptions.

Subjects: subject: Foreign aid, development, economic backwardness
subject: F35, O24

description: The article examines a number of issues regarding the merits of foreign aid as an instrument for the development of backward countries that have yet to receive adequate attention. The author argues that Foreign aid has obscured the deep seated factors beneath differences in prosperity and that economic development requires cultural change in the backward countries and structural changes in the advanced countries. Furthermore, it is argued that foreign aid leads to an ineffective use of the world’s supplies of capital and promotes concentration of power both in the rich and poor countries. Finally, some other ways to encourage economic development in the backwards countries are explored. JEL: F35, O24

description: Einstein's general relativity is the best available theory of gravity. In recent years, spectacular proofs of Einstein's theory have been conducted, which have aroused interest that goes far beyond the narrow circle of specialists. The aim of this work is to offer an elementary introduction to general relativity. In this first part, we introduce the geometric concepts that constitute the basis of Einstein's theory. In the second part we will use these concepts to explore the curved spacetime geometry of general relativity.

description: The main result of this paper is that one cannot hear orientability of a surface with boundary. More precisely, we construct two isospectral flat surfaces with boundary with the same Neumann spectrum, one orientable, the other non-orientable. For this purpose, we apply Sunada's and Buser's methods in the framework of orbifolds. Choosing a symmetric tile in our construction, and adapting a folklore argument of Fefferman, we also show that the surfaces have different Dirichlet spectra. These results were announced in the {\it C. R. Acad. Sci. Paris Sér. I Math.}, volume 320 in 1995, but the full proofs so far have only circulated in preprint form.

title: Analysis of production planning and control systems for automotive powertrain assembly lines concerning the level of decentralization in the context of Industrie 4.0

subject: assembly line

description: 8 Abstract The motivation to address the subject of Industrie 4.0 developed during the lectures of Professor Sihn, who mentioned Industrie 4.0 as a promising opportunity for manufacturing companies. As the MBA program is focused on automotive industry and logistics is a core theme of the program, the idea was born to investigate production planning and control (PPC) in an automotive plant in context with Industrie 4.0. The expectations of Industrie 4.0 concerning the increase in productivity and mastering of complexity through the introduction of cyber-physical systems and the internet of things in the manufacturing world are high. The decentralization of decision making in cyber-physical production systems is propagated as a key function to improve the fulfillment of the logistic objectives. The master thesis introduces Industrie 4.0 and production planning and control in terms of the degree of centralization and autonomous control. The evaluation of the degree of decentralization is approached to be measured in terms of autonomous control, based on the use case and the application of production planning and control for an automotive powertrain plant. The research is focused on short-term scheduling and sequencing. The current state of the PPC tasks are evaluated by SWOT analysis and a possible target concept in terms of Industrie 4.0 is outlined. The current state of PPC is a hybrid system, where the assembly line is planned centrally by the PPC department and the upstream component lines are planned retrograde at the shop-floor in mutual cooperation with the PPC department. The level of autonomous control of the system elements is rated as low. The opportunities that are expected with Industrie 4.0 technologies increase with the importance of the availability of real-time data. The outlined manufacturing system is based on lean principles and flow lines, as they are set up today. The application of cyber-physical systems enhances the production planning and control systems to optimize the models of MES/APS tools to create a self-optimizing real-time model of the production that can optimize the fulfillment of the logistic objectives even in case of disruptions, based on analysis of historical data of disruptions.
