Abstract:
This is a review of the geometry of quantum states using elementary methods and pictures. Quantum states are represented by a convex body, often in high dimensions. In the case of [Formula: see text] qubits, the dimension is exponentially large in [Formula: see text]. The space of states can be visualized, to some extent, by its simple cross sections: Regular simplexes, balls and hyper-octahedra. a When the dimension gets large, there is a precise sense in which the space of states resembles, almost in every direction, a ball. The ball turns out to be a ball of rather low purity states. We also address some of the corresponding, but harder, geometric properties of separable and entangled states and entanglement witnesses. “All convex bodies behave a bit like Euclidean balls.” Keith Ball

Abstract:
Silicon, with its great abundance and mature infrastructure, is a foundational material for a range of applications, such as electronics, sensors, solar cells, batteries, and thermoelectrics. These applications rely on the purification of Si to different levels. Recently, it has been shown that nanosized silicon can offer additional advantages, such as enhanced mechanical properties, significant absorption enhancement, and reduced thermal conductivity. However, current processes to produce and purify Si are complex, expensive, and energy-intensive. Here, we show a nanopurification process, which involves only simple and scalable ball milling and acid etching, to increase Si purity drastically [up to 99.999% (wt %)] directly from low-grade and low-cost ferrosilicon [84% (wt %) Si; ∼$1/kg]. It is found that the impurity-rich regions are mechanically weak as breaking points during ball milling and thus, exposed on the surface, and they can be conveniently and effectively removed by chemical etching. We discovered that the purity goes up with the size of Si particles going down, resulting in high purity at the sub–100-nm scale. The produced Si nanoparticles with high purity and small size exhibit high performance as Li ion battery anodes, with high reversible capacity (1,755 mAh g−1) and long cycle life (73% capacity retention over 500 cycles). This nanopurification process provides a complimentary route to produce Si, with finely controlled size and purity, in a diverse set of applications.

Commercial Y2O3 powders were subjected to high energy ball milling in a planetary ball mill using high purity alumina balls and vial. The refined Y2O3 power ,with commercial high-purity Al2O3, Cr2O3 and Yb2O3 powders, were used as raw materials. Transparent ytterbium and chromium codoped yttrium aluminum garnet (Yb,Cr:YAG) ceramics were fabricated by a solid-state reaction method. The Yb,Cr:YAG ceramics exhibit a pore free structure and the average grain size is about 10 micron. The strong absorptions at 940 and 968 nm of Yb3+ are suitable for InGaAs diode laser pumping, and there is an absorption band at 1030 nm, which is suitable for passive Q-switch laser output at 1030 nm. Transparent Yb,Cr:YAG ceramics may be a potential material for compact, efficient, high-stability diode-laser-pumped passive Q-switched solid-state lasers.

Abstract:
Abstract The major constituents of sand are silica and silicates. The facile and low-cost purification technology of silica from natural sand is of magnificent importance to the industrial applications of silicon-based materials. Herein, we report a green, low-cost, and universal method to purify silica from natural sand. Sand from deserts, rivers, and seas is selected as the representative of natural sand. The initial purity of silica is 52.1 wt% for desert sand, 39.3 wt% for river sand, and 35.8 wt% for sea sand. High-purity silica has been successfully separated and purified from natural sand via ball milling, reacting with 30 bar CO2 and hydrochloric acid. The purity of silica derived from natural sand reaches >96 wt%. In this work, the mechanism for the purification of silica from natural sand is discussed. This study provides a new method to separate high-purity silica from natural sand without the generation of toxic and harmful substances.

Commercial purity titanium samples were gas nitrided for 3, 5, 7 and 12 h at 1250°C. TiN layers with nitrogen diffusion zones were formed on the surfaces, which caused an increase in the surface hardness with respect to the processing time. In addition, nitriding provided a reduction in friction coefficient and an enhancement in wear resistance against an alumina ball under dry sliding conditions.

Abstract:
High energy ball-milling of metallic powders is used extensively to achieve structural refinement. In recent years it has been found that cold-milling can induce transformations to highly metastable phases.In particular, the elemental mixing at the atomic-scale in certain systems may eventually lead to solid-state amorphization reactions (SSAR) after short periods of time. A problem that often arises in using this technique is contamination of the product from the grinding balls and container material.In this note we describe such a development in the microstructures that evolve during SSAR of a mixture of 75 atm% Ni and 25 atm% Ta high-purity powders processed for 17h in a planetary mill using WC + Co balls and container. The average composition of the ball-milled powders determined by EDS-analysis in a SEM was Ni75Ta25. X-ray diffraction confirmed the formation of an amorphous phase and also revealed the presence of sharp crystalline peaks identified as WC hexagonal phase (a=0.291 nm and c=0.283 nm); no detectable crystalline peaks from the initial Ni or Ta powders were observed. For TEM observations, small quantities of the ball-milled powders were embedded in epoxy and subsequently sectioned with a diamond knife using a Dupont-6000 ultramicrotome.

Abstract:
To value-added utilization of the rice straw, two types of lignin were extracted from the by-products of sugar production. The ether-extracted lignin with a purity of 98.7% was extracted from the pretreatment filtrate with two times the concentrated filtrate volume of ether, where the lignin yield was 6.62 mg/g of the rice straw. The ball-milled lignin with a purity of 99.6% was extracted from the milled enzymatic hydrolysis residue with a 1,4-dioxane solution, where the revolution speed and grinding time were 300 rpm and 12 h, respectively. The yield of ball-milled lignin was 34.52 mg/g of the rice straw, which was 421.5% higher than that extracted from extract-free rice straw. In the process of rice straw pretreatment and lignin extraction, 76.43% by mass of phosphotungstic acid catalyst and approximately 98% by volume of 1,4-dioxane solution could be recycled and reused. Compared with the soda lignin extracted from papermaking black liquor, the scavenging rates of DPPH radical and ABTS+ radical of ether-extracted lignin increased by 36.26% and 41.18%, respectively, while the above scavenging rates of ball-milled lignin increased by 30.22% and 37.75%, respectively. Moreover, the reducing power of the two extracted lignins was also stronger than that of soda lignin. The ether-extracted lignin and ball-milled lignin have the potential to be developed as natural macromolecular antioxidants.

Abstract:
Baal teshuvas are traditionally observant Orthodox Jewish individuals who were previously not religiously observant and chose to become observant at a later juncture in their lives. This population is at risk of psychosocial dysfunction, particularly in the area of marriage, but little or no research has been conducted with this population. The purpose of this study was to study how 1 factor, the laws of family purity, an ancient set of Jewish laws governing sexual behavior between husbands and wives, may have an effect on marital satisfaction among baal teshuvas. Areas of marital satisfaction were measured by the Revised Dyadic Adjustment Scale, Triangular Love Scale, and New Sexual Satisfaction Survey. Relational-cultural theory and relational spirituality were used to describe how spirituality affects individual well-being and the quality of one's relationships with others. A sample of 44 male and 59 female baal teshuvas completed the surveys. MANOVAs and 2-factor ANOVAs were conducted to compare the effects of gender and level of observance of family purity laws on marital satisfaction survey results. Results indicated a significant difference only by gender on the sexual satisfaction measure, although it is not known how much of a difference there was between the genders. This study reinforces indications from past research that studying sexual satisfaction in marriages is an increasingly important area of study and clinical practice. This study may lead to positive social change by identifying methods to improve marital satisfaction in the newly religious population. In addition, the results may provide further evidence supporting the already known positive psychological benefits of the laws of family purity.

Abstract:
Balinese puris are the residences of the traditional ruling elite of Bali, the ksatria. The puris provided the rajas and the lesser political leaders in Bali until the challenge to Satria hegemony posed by Dutch colonialism. In Badung (South Bali), Dutch ascendancy was marked by the massacre known as the puputan Badung, in 1906, which wiped out most of the royal families of puri Denpasar and puri Pamacutan. After the puputan, puri Denpasar and Pamacutan were replaced by puri Satria and puri Kanginan-Pamacutan respectively. Very few studies have been made of the Balinese puris in Badung, after the fall of puri Denpasar and Pamacutan so that the people of Badung themselves do not clearly understand the political role of these puris. This thesis is an attempt to study the rivalry between the resurgent puri Satria and its main local antagonist, puri Pamacutan. The latter co-operated with the Dutch colonial authority, while the survivors of the Badung massacre rebuilt puri Satria as a centre of opposition to the Dutch. The time frame (1906-1950) for this research reflects a period of turmoil and change in Bali, from the Dutch invasion (of South Bali), to the Japanese occupation, through the struggle for independence and the incorporation of Bali into the East Indonesian State to the eventual union with the Republic of Indonesia. The major topic of interest will be the strongly contrasting roles played by the traditional leadership of the two puris in the maintenance of political hegemony through the first half of the twentieth century.

Abstract:
Legal pressures fundamentally shaped English satire during the long eighteenth century. Rather than being purely repressive, however, the law often encouraged authors and their booksellers to find creative ways to write and publish satire to circumvent both the authorities and the courts. As part of their strategy, satirists developed verbally evasive forms of satire, producing coyly ironic, densely allegorical, and circumlocutory rhetorical styles markedly unlike the seventeenth century’s most bald-faced manuscript lampoons. Shifty printers and booksellers also complicated the mechanics of detection and prosecution through a host of publication ruses. In effect, the elegant insults, comical periphrases, and booksellers’ tricks that came to typify eighteenth-century satire were a way of writing and publishing born of legal necessity. Early on, these emergent satiric practices stymied the authorities and the courts. But they also eventually led to new legislation and innovative courtroom procedures that targeted satire’s most routine evasions. Especially important were a series of eighteenth-century rulings that increased the legal liabilities of printers and booksellers and that expanded and refined doctrines for the courtroom interpretation of verbal ambiguity, irony, and allegory. By the mid-eighteenth century, satirists and their booksellers faced a range of newfound legal pressures. Rather than disappearing, however, personal and political satire began to migrate to dramatic mimicry and caricature. Such acoustic and visual forms relied less on verbal ambiguity and were therefore not subject to either the provisions of preperformance dramatic licensing or courtroom interpretive procedures that had earlier enabled the prosecution of printed satire.

Abstract:
This chapter examines Whitman’s entanglement within the broader politics of labor relations in the mid-nineteenth century. Whitman is seen as thinking through an alternative figuration of Marx’s labor theory of value, with the various corporeal metaphors and formal experiments in his poetry serving as a counterpart to Marx’s gothic dystopian depictions of alienated labor. The laboring body becomes a conceptual balm in Whitman’s poetic imaginary, informing the dimensions of his alternative social vision. His own complicity in the fluctuating tensions of his laboring environment, embodied chiefly by the rising tensions between slavery and the expanding market, rescued his poetic vision from restating the reactionary vocational essentialisms that defined the popular labor movements of the 1850s. Ultimately, he articulated a politically subversive poetics that resisted contemporary fictions of racial purity, and along with it any transparent notion of free market exchange.

Abstract:
Note that Ω=Ω×[0, 1] is a particular case where the boundary layers are purely horizontal or purely vertical. In the general case of an open domain Ω, the boundaries have various orientations. As long as the tangential plane ∂Ω is not vertical, the boundary layers are of Ekman type, with a size of order where ν is the normal of the tangential plane. When ν.r→0, namely when the tangential plane becomes vertical, Ekman layers become larger and larger, and degenerate for ν.r=0 in another type of boundary layer, called equatorial degeneracy of the Ekman layer. We will now detail this phenomenon in the particular case of a rotating sphere. Mathematically, almost everything is widely open! Let Ω=B(0,R) be a ball. Let θ be the latitude in spherical coordinates. The equatorial degeneracy of the Ekman layer is difficult to study. We will just give the conclusions of the analytical studies of. The Ekman layer is a good approximation of the boundary layer as long as |θ|≫E1/5. For |θ|≪E1/5 the Ekman layer degenerates into a layer of size E2/5. • for |θ|≫(εν)1/5, Ekman layer of size • for |θ| of order (εν)1/5, degeneracy of the Ekman layer into a layer of size (εν)1/5 in depth and (εν)2/5 in latitude. Let us now concentrate on the motion between two concentric rotating spheres, the speed of rotation of the spheres being the same. In this case, Ω=B(0,R) − B(0, r) where 0<r<R. Keeping in mind meteorology, the interesting case arises when R − r ≪ R: the two spheres have almost equal radius. Let us study the fluid at some latitude θ. If θ ≠0, locally, the space between the two spheres can be considered as flat and treated as a domain between two nearby plates. The conclusions of the previous paragraphs can be applied. Two Ekman layers are created, one near the inner sphere and the other one near the outer sphere.

Abstract:
Oxygen content in air is approximately 21% by volume. With many industrial uses, mainly in the manufacture of steel and chemicals, for metal cutting, welding ,hardening & scarfing, it is being transported as a non-liquefied gas at pressures of 138 bar (13800000 Pa) or above, also as a cryogenic fluid at pressures and temperatures below 13.8bar (1380000 Pa) & −146.5°C (126.65K). Commonly we found air separation plants produce ultra-pure oxygen (> 99.9% purity) via liquefaction of atmospheric air and separation of the oxygen by fractionation and thereby transported to the needy areas via pipelines. The research efforts directed towards technical assessment to establish the correlations between valve construction and turbulence and solving the complications in the transported ultra-pure oxygen gas in the pipelines and through mounted valves. Hence, it is necessary to study the performance, complexities and fire hazards associated with the valves transporting it and the preventive measures to avoid any catastrophic failure in ultra-pure gaseous oxygen services. The study was conducted on two isolation valves — each of ball and globe of relative size. It was realized that velocities of the ultrapure gaseous oxygen on the impingement sites inside the valve are beyond the safe limit as recommended by European Industrial Gas Association (EIGA) [4] and various other prominent industrial gas manufacturers. Moreover, globe valve gave relatively less turbulence and velocity at initial opening of the valve. The study revealed that majority of health hazards & accidents on industrial usage of ultra-pure gaseous oxygen media are the result of the inadequate awareness of the degreasing or cleaning and optimum material selection and construction of the valve and fittings on the industrial pipeline.

Abstract:
Advancement in materials science and manufacturing processes helps in expanding the application span of materials in biotechnology. The technological development of biocompatible materials aids in improving health conditions, cancerous treatment, organ implants, and as well as provides several techniques to patient treatment. Hydroxyapatite (HAP) is considered as a potential material for orthopedics and dental implants due to its eminent biocompatibility and natural apatite characteristics. It is regarded as viable and cost effective solution of many biomedical applications. Major challenges in expanding the application span of HAP include obtaining optimum mechanical, chemical, and biological properties simultaneously while making its manufacturing processes cost effective. The main purpose of the current work is to synthesize and characterize high strength HAP with high degree of crystallinity and purity, which could be able to fulfill the requirements of modern biological materials. In this work, egg-shell which is considered as garbage is utilized as calcium source to synthesize HAP. Initially, egg-shells are properly cleaned with distilled water and dried. Ball milling operation is used to produce egg-shell particles of nano to micron range. The particles then mixed with controlled amount of phosphoric acid. The mixture is then sintered by heat treating at 900°C for 2 hours. The heat treatment (sintering) process is used to enhance the density as well as strength of egg-shell material. After synthesis of HAP, it is characterized through X-ray diffraction, scanning electron microscopy, and laser particle analyzer. Composition of HAP is investigated through XRD. Furthermore, surface topography of nano-crystalline HAP powder is measured through Scanning Electron Microscope while particle size distribution is found through laser particle analyzer. It is found that the addition of phosphoric acid in milled egg-shell and heat treatment give rise HAP in the sample. In addition, particle size varies from hundreds of nanometers to several micrometers. The results and analysis of the current work may provide insight of different properties which may lead to the development of optimum and cost effective HAP material. The current study could be further extended in increasing application envelop of biocompatible materials.

Abstract:
Splenocytes from a Balb/c mouse immunized with purified human protein S (PS) were fused with murine hybridoma cell line SP2/0-Agl4 and cultured in Iscove's medium without addition of fetal bovine serum. Hybrid supernatants were screened for the presence of specific antibodies by solid-phase ELISA and cloned by the limiting dilution technique. Pour clones, named S2, S3, S8, and S10, were selected, recloned several times, and injected intraperitoneally into Balb/c mice for the production of antibody-rich ascitic fluid. The monoclonal antibodies (Mabs), all of IgGl subclass with k light chain, were purified from ascitic fluid by Protein-A chromatography. The specificity of Mabs was controlled by the immunoblotting technique: the Mabs appeared to react only with two plasma proteins, one with a MW of about 70.000 dal tons comigrating with purified PS, and the other with a MW >300.000 da that is likely to be the C4b-binding protein-PS complex. No interaction has been observed with PS-depleted plasma. As tested by a fluid phase radio immunoassay, the binding of Mabs to PS was significantly higher in the presence of EDTA while was totally inhibited in the presence of Ca2+. Scatchard plot analysis of the binding between 125I-PS and Mabs showed that the binding affinity of the antibodies ranged from 108 to 109 1/mol. Each EDTA-dependent Mab was then immobilized on Sepharose 4B-CNBr and used to purify PS from barium precipitation of citrated plasma. The fraction eluted with 2 mmol of CaCl2 from the immunoadsorbent appeared to contain only two proteins when stained with Cocmassie Blue. By immuno blotting, all Mabs reacted with both proteins, one comigrating with purified PS and the other with a MW >300.000. Essentially homogeneous PS, free from the high MW component, was obtained when the barium citrate adsorbate was applied to a DEAE-Sephadex column and the protein peack containing the balk of PS was sussequently applied to the immunoadsorbent and eluted with 2 mmol CaCl2.In summary, we have described an unusual set of EDTA-dependent monoclonal antibodies to PS and their use for the purification of homogeneous protein S from human plasma.

Abstract:
A 3D elastic-plastic rough contact (EPC) solution and code is developed using a modified semi-analytical method. The total surface deflection is induced by the contact pressure and plastic strain. A purely elastic contact field and a residual field arising from the plastic deformation are simulated iteratively to gain the final approximate solution for the elastic-plastic rough contact. Frictionless normal contact between a rigid ball and an elastic-plastic half space with polished, turned, and honed rough surfaces was numerically simulated using the developed EPC code. The distributions of surface pressures, real contact area, total stresses, residual stresses, residual displacements, and plastic strains are obtained through simulation. The effects of surface roughness, wavelength, and plastic hardening behavior upon the calculated results are analyzed.

Abstract:
Abstract Several methods exist for the determination of profiles of cutting tools which work by wrapping. Most of these methods are based on the envelope theory and most often require cumbersome analytical formulations and the solution of equations not always easy to resolve. This work, based on the principle of minimal distance first proposed in a previous work of the second author, presents a new purely numerical method for the calculation of the active profile of the cutting tools which work by wrapping (direct problem) as well as for the estimation of the effectively generated surface on the workpiece when the tool is known at discrete points (inverse problem). The method can be used for any nonstandard profiles when an analytical description of the surfaces is not available. Several examples are shown for machining ball screws and parts of helical pumps.

Abstract:
The nature of the constitutive contact force law utilized to describe contact-impact events plays a crucial role in predicting the dynamic response of multibody systems. The main goal of this work is present a survey of the literature on the most relevant penalty-force based approaches for multibody dynamic simulations. In this process, the fundamental characteristics of the purely elastic and the dissipative contact force models are analyzed, namely the models which have been developed based on the Hertz contact law. In particular, the different models are compared in this study for a simple impact problem for the sole purpose of comparison of the models and examining their validity compared to those from experiments. Results obtained for a classical ball impact on a massive surface are presented and used to discuss the main assumptions and procedures associated with the different penalty-force approaches. The force models are found to be quite well representative of the contact forces in an impact, and that they can be applied for the analysis of impact in more complex systems a such as the ones in planar and spatial multibody mechanical systems.
