Inception cavitating flow around axisymmetric blunt body was studied based on the experiments and numerical simulations. A high-speed video camera was used to observe the process and structure of cavitation inception. A Partially-Averaged Navier-Stokes(PANS) method which was a hybrid RANS/LES turbulent model was applied in numerical simulations. The results show that the inception cavities which are spindle-like generate in the separate vortex of the blunt body. Beside moving along with changing vortexes in the field, inception cavities rotate themselves around their longer axes of spindle-like cavities. Inception cavities move downstream far less slowly than the inflow does. It is shown in both experimental and numerical methods that during the whole developing process of travelling incept cavities, they move downstream by the velocities which are about 10% to 40% of mainstream velocity in this study.


The transition from combustion vehicles towards a new electrical system friendly to the environment, is a decision to be taken by carrier based on cost-benefit analysis which generates buying it, and contribute to society not only for the service they provide, but to prevent air pollution we breathe, and if we add the future energy supply, since the Ecuadorian State in 2016 will provide the whole country of this important resource. The study focuses on two parts: the first on surveys of taxi owners to describe their perception of the integration of electric vehicles, and the second in determining the economic and financial feasibility of acquiring the vehicle Nissan Leaf by the member of the cooperative taxi. The most important conclusion is that the carriers are willing to buy an electric vehicle to mitigate the emission of toxic gases, and that its decision would save 50% in annual operating costs of your vehicle.


Intracellular delivery of freezing‐tolerant trehalose is crucial for cryopreservation of red blood cells (RBCs) and previous strategies based on membrane‐disruptive activity usually generate severe hemolysis. Herein, a dynamic membrane‐active glycopeptide is developed by grafting with 25% maltotriose and 50% p‐benzyl alcohol for the first time to effectively facilitate entry of membrane‐impermeable trehalose in human RBCs with low hemolysis. Results of the mechanism acting on cell membranes suggest that reversible adsorption of such benzyl alcohol‐grafted glycopeptide on cell surfaces upon weak perturbation with phospholipids and dynamic transition toward membrane stabilization are essential for keeping cellular biofunctions. Furthermore, the functionalized glycopeptide is indicative of typical α‐helical/β‐sheet structure‐driven regulations of ice crystals during freeze−thaw, thereby strongly promoting efficient cryopreservation. Such all‐in‐one glycopeptide enables achieving both high cell recovery post‐thaw >85% and exceptional cryosurvival >95% in direct freezing protocols. The rationally designed benzyl alcohol‐modified glycopeptide permits the development of a competent platform with high generality for protection of blood cells against freeze‐stress.


The reproductive biology of the dioecious Viscum cruciatum, one of the few viscaceous mistletoes occurring in Europe, was investigated. The male flower is 7.2 mm long and lemon-scented, produces ca. 58,000 pollen grains, and has a dry mass of 14 mg, and thus a low relative staminate effort (RSE) value of 4,059. Female flowers, ca. 3 mm long, 2.7 mg dry mass, secrete small amounts of nectar (0.05 mg sugar/d). A stigma is not apparent. Flowers inside nylon bags (i.e., insect-free) set significantly less fruit than control branches open to natural pollination. Pollination is performed by insects. Flowers bagged against insects but not wind set some fruit. Flowers bagged with dense cloth excluding wind and insect pollination did not set any fruit. Agamospermous embryo production does not take place in this species and cannot be the cause of the shift in sex-ratio toward females. Fruits can contain one (45%), two (43.6%), three (11%), or four (0.3%) embryos, which may not be true polyembryony but may result from the partial or complete fusion of the chlorophyllous endosperm. Fruit size is not correlated with the number of embryos per "seed" but probably with other ecological or maternal factors. Although a dormancy period was not observed, flowering and fruiting are restricted mainly to winter. Nevertheless, the pattern of flowering differed significantly between the two years studied, being longer and less overlapping during 1991 (only in the females). The fruit set was also lower in 1991.


Solid‐state thermoelectric (TE) devices are known for converting solar energy and waste heat into electricity, which provides a substitute path for energy production and utilization to commence the challenges of energy sustainability. To develop TE devices, it is important to identify thermoelectrically active materials with the potential converting solar energy and heat into electrical energy. In ambient settings, TE devices are one of the most pollution‐free methods of energy conversion since it is noiseless, essentially maintenance‐free, and able to provide electricity continuously for several years. A surge in interest in TE harvesting for diverse uses, including extracting waste heat from automobile exhaust and industrial processes has occurred in recent years. For an efficient TE device, a number of variables must be addressed. These include the availability of TE materials with high ZT, construction of ohmic connections between thermoelements and metallic interconnect, material engineering and defects systems, and the control of maximum heat transport through the device. The current review summarized a recent understanding of a reliable and eco‐friendly strategy for synthesizing pure MgAgSb alloy and its TE performance enhancement. First, a discussion on the various strategies employed to improve ZT and band structure determination is described. Then, we provided an overview of excellent TE performance, applications of bandgap engineering to enhance TE ZT value and their capacity to produce energy, and good quality nanostructured a‐MgAgSb to produce long‐term, thermally stable microstructure. Finally, we will look at how well a single‐leg device converts power. The current mysteries, along with future perspectives and challenges for this material system, are described in the outlook section.


The purpose of this paper is to examine and improve some algorithms in urban land gradations. Methods of documentation and comparative analysis are employed. After careful review of current approaches applied in land value appraisal, the paper argued that land rank played a too significant role in determining land value. Based on some experience in land value investigation in Taiyuan City, the author proposed specific corrections, and argued that it is proper for land valuation in middle-size cities.


We investigate large set axioms defined in terms of elementary embeddings over constructive set theories, focusing on $\mathsf{IKP}$ and $\mathsf{CZF}$. Most previously studied large set axioms, notably the constructive analogues of large cardinals below $0^\sharp$, have proof-theoretic strength weaker than full Second-order Arithmetic. On the other hand, the situation is dramatically different for those defined via elementary embeddings. We show that by adding to $\mathsf{IKP}$ the basic properties of an elementary embedding $j\colon V\to M$ for $\Delta_0$-formulas, which we will denote by $\mathsf{\Delta_0\text{-}BTEE}_M$, we obtain the consistency of $\mathsf{ZFC}$ and more. We will also see that the consistency strength of a Reinhardt set exceeds that of $\mathsf{ZF+WA}$. Furthermore, we will define super Reinhardt sets and $\mathsf{TR}$, which is a constructive analogue of $V$ being totally Reinhardt, and prove that their proof-theoretic strength exceeds that of $\mathsf{ZF}$ with choiceless large cardinals.


Simple Summary In Australia, most cats and dogs entering animal shelters and pounds are classed as strays, typically from low-income areas. Most dogs and an unknown proportion of stray cats are escaped or wandering owned pets. Many of these stray animals are euthanized, negatively impacting the mental health of staff involved, and increasing the risk of depression, traumatic stress, substance abuse and suicide. Modern sheltering practices aim to reduce the number of stray cats and dogs, which reduces shelter admissions and euthanasia. Australian pet owners (n = 2103) were surveyed about their attitudes towards four types of pet confinement. Dog owners showed the strongest support for confining dogs to the owners' property whenever unsupervised and less support for confining dogs inside the house at night (54% agreed), while 23% believed dogs had a negative impact on wildlife. Cat owners showed the strongest support for confining cats inside at night. Cat owners' non-supportive attitudes towards cat confinement were partly because of higher concern for cat quality of life and lower concern about their cats' predation behaviors, compared to non-cat owners. These results provide valuable information to inform more effective strategies to reduce stray animals and associated issues. Abstract Most cats and dogs entering Australian animal shelters and municipal facilities are classed as strays, typically from low socio-economic areas. Contemporary practices increasingly focus on proactively reducing the number of stray animals, which requires further understanding of factors associated with straying animals, including pet confinement. Australian cat and dog owners (n = 2103) were surveyed to investigate attitudes towards four types of pet confinement and how these were influenced by social norms, demographics and concerns about pet quality of life and potential wildlife predation. Dog owners showed the strongest support for confining dogs to the owners' property whenever unsupervised (98% agreement) and less support for confining dogs inside the house at night (54% agreement), and only 23% believed dogs had a negative impact on wildlife. Cat owners showed the strongest support for confining cats inside the house at night (89% agreement). Cat owners' non-supportive attitudes towards cat confinement were partly because of higher concern for cat quality of life and lower concern about their cats' predation behaviours, compared to non-cat owners. The findings provide valuable information to inform more effective strategies to reduce stray animals which would reduce shelter admissions, euthanasia, costs, nuisance issues, potential wildlife predation and negative mental health impacts of euthanasia on staff. Strategies to reduce strays include assisting low-income pet owners to install effective fencing and programs to increase identification. Informing cat owners about bedtime feeding is recommended to assist with night containment, and providing high-intensity free sterilization of owned and semi-owned cats targeted to areas of high cat impoundments is also recommended.

This work seeks to explain intuitive perception—those perceptions that are not based on reason or logic or on memories or extrapolations from the past, but are based, instead, on accurate foreknowledge of the future. Often such intuitive foreknowledge involves perception of implicit information about nonlocal objects and/or events by the body's psychophysiological systems. Recent experiments have shown that intuitive perception of a future event is related to the degree of emotional significance of that event, and a new study shows that both the brain and the heart are involved in processing a pre-stimulus emotional response to the future event. Drawing on this research and on the principles of quantum holography, I develop a theory of intuition that views the perception of things remote in space or ahead in time (nonlocal communication) as involving processes of energetic resonance connecting the body's psychophysiological systems to the quantum level. The theory explains how focused emotional attention directed to the nonlocal object of interest attunes the bio-emotional energy generated by the body's psychophysiological systems to a domain of quantum-holographical information, which contains implicit information about the object. The body's perception of such implicit information about things distant in space/time is experienced as an intuition.

The Elizabethan poet thus neatly phrased his concept of biological motivation. Perhaps he has said all there is to say. The thermodynamically improbable state of life has continued to invite speculations to explain it and to encourage the framing of hypotheses which serve to rationalize the uncertainties of existence or to fortify confidence in its maintenance. I have stated elsewhere that "Hegel's formula of thesis-antithesis-synthesis appears merely to outline a behavior pattern in the approach ofman to an idea" (1). The coloration of biological thought has frequently reflected the preoccupation of the age in which it arose. Witness the attractiveness ofmechanical analogues or models—the symbolism of the heat engine or, later, of the storage battery (cf. 2) or, more recently, of stabilization through inverse or negative feedback, as in "high-fidelity" electronic power amplifiers. In view ofthe maze ofthe living process, those concepts which appear to simplify or unify or suggest perfection of mechanism and the inviolability of the body image are more readily acceptable. The longevity of ideas is favored also by a baser element in intellectual makeup —complacency and resistance to change, rejection of the new. The concept of "homeostasis," overshadowed in recent years by Selye's concept of the "adaptation syndrome," has long influenced, if not dominated, the understanding of the body's ability to maintain itself as a "self* Professor and Chairman, Department of Biochemistry, Graduate School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania.

Whiteness in its dominant contemporary form in Australian society is Anglocised, institutionalised and culturally based. Australian culture is less White than it used to be, but Anglocised Whiteness forms the centre where white men established institutions encouraging a possessive investment in whiteness (Moreton-Robinson 1998:11). Subsequent governments, Labor and Liberal/Coalition, legitimated the appropriation of Indigenous lands, racialised incarceration and enslavement and limited naturalised citizenship to white immigrants (Lipsitz 1998). While blackness was congruent with Indigenous subjugation and subordination, patriarchal whiteness was perceived as being synonymous with freedom and citizenship.-----

This paper argues that patriarchal whiteness is imbued with power. It confers dominance and a property right that has consequences for the distribution of wealth, status and opportunity in Australia for Indigenous people. This will be demonstrated through an analysis of the discourse about native title with reference to the Mabo and Wik decisions, amendments to the Native Title Act (1993), (Cth) and recent decisions made by the United Nations Committee on the Elimination of Racial Discrimination. Patriarchal whiteness is an invisible unnamed organising principle that surreptitiously shapes social relations and economic development. Indigenous people continue to be the most impoverished group in Australian society in critical areas such as housing, health, education, criminal justice, employment and economic development. Race and gender are salient in determining who rules and who accumulates property and wealth (MacKinnon 1993:367).


There are several factors in assessing the quality of a hospital, namely the level of expertise of doctors owned, quality supporting facilities and infrastructure, and the queuing system implemented by the hospital. If the arrival rate and level of service provided to the patient are not balanced it will cause initiation for the patient and a loss to the hospital because the patient tends to switch to a hospital that has a more optimal level of service. In this study, the method used is a simulation method using flexsim software. The data were obtained using primary data that has been observed directly on the outpatient service queue system of dr. Sardjito Hospital. From the data searched for data distribution using flexsim feature, experfit. During the time the simulation was run found obstacles in the polyclinic queue of obstetrics and obstetric diseases which is in accordance with direct blame. It is known that the average waiting time of the polyclinic queue is for 3.5 hours which is classified as very long and the utilization of doctors works by 44.65%. So there need to be improvements in the form of alternative models in the queue, namely by increasing the number of rooms and doctors who work with as many as 2 and 3 units. From the results of a significant average waiting time from the initial model change with the alternative model, which is as much as 3 units for 2.6 hours with a ratio of 0.9 hours that became the chosen alternative. Based on the research can help the hospital in providing queue services in the queue of obstetric polyclinics and obstetric diseases to patients and the doctor's working time is more optimal and does not exceed the ability of the doctor's work.

The article examines the peculiarities of the media discourse of the social network Vk.com and the instant messaging service Telegram. The authors consider the media discourse of politicized social media subpublics and channels as a factor that influences communication within the communities of these media. The methods used include discourse analysis of comments on the three key news stories of 2022 and LDA analysis of media discourse, which allow us to determine the criteria of group identity and the tendency to form monological or dialogical models of communication.


The project mainly developed a near-field electrospinning platform with a controlled three-axis positioning of speed, torque and position to produce compact and high-quality piezoelectric fibers. In this study, we designed a high response servo motor controller to develop a high response rate, accurately located and stabilized mobile device through bandwidth and system time delay calculation. Then we combine the unique development of near-field electrospinning technology with high-speed response and accurate positioning moving device. A write-through near-field electrospinning system (DWs-NFES) was developed, and it used to fabricate functional fibers, such as polyvinylidene fluoride (PVDF).


Abstract Background: Lipomas are benign, slow-growing tumors frequently subcutaneous and asymptomatic, intramuscular lipoma constituting a rare subtype. However, a lipoma occurring nearby the proximal radius may cause posterior interosseous nerve (PIN) entrapment. Case presentation: We described an uncommon case of a 45-year-old-man with a history of progressive, painless proximal right (dominant) forearm swelling for 4 months associated with PIN entrapment syndrome, presenting as fingers extension weakness. Intramuscular lipoma was observed in the supinator muscle in the magnetic resonance imaging (MRI). Lipoma surgical excision and release of the PIN through proximal forearm direct anterior approach was performed. Results: The histopathological examination confirmed the diagnosis of benign intramuscular lipoma. The follow-up of the patient showed full recovery within three months postoperatively. Discussion: Intramuscular lipoma is rare; however, it could originate from supinator muscle in the forearm, presenting with vague pain and could lead to compression of nearby neurovascular structures such as the PIN. Clinical evaluation and imaging studies, especially MRI, are crucial for diagnosis. If neural compression is evident, surgical resection is mandatory. Conclusion: Intramuscular lipoma entrapping PIN is rare and requires early clinical diagnosis confirmed by imaging and neurophysiological studies, surgical excision being the method of choice for optimum functional outcomes.


Biphasic constant current (CC) stimulators are used in functional electrical stimulation applications. These stimulators require positive and negative high voltage (HV) sources in order to deliver the programmed CC pulses to load. For example, applying symmetrical biphasic CC pulses with 50 mA amplitude to a $1 \mathrm{k}\Omega$ load requires positive and negative supply rails of 50V and -50V, respectively. In this study, a HV source based on a switched inductance boost DC/DC converter and a switched capacitor voltage inverter is designed and implemented in order to satisfy the HV requirements of biphasic stimulators. Performance of the proposed HV topology is satisfactory for CC pulses of 35 mA applied to a $1\mathrm{k}\Omega$ load.


Abstract: When the winds of change blow, some people build walls, others build windmills. Innovation has taken over as the hub of quality improvement and each spoke of life is being driven by continuous improvement of these innovations. In an inexorably serious ecosystem, components such as innovation and quality can continue to prompt an upper hand. A comparative study of various world class consulting organizations, observed that innovation was among the main three vital needs for 95% of organizations, besides evaluation and metrics (1,2,3). This is to a limited extent because of innovations having the option to give extraordinary deliverables and iterations which make more prominent incentives for end users, just as monetary advantages for the organization (4). Further exploration proposes "Quality" is at the forefront of innovations. Quality management applications have likewise been related with functional and monetary execution permitting firms to accomplish objectives on priority at the grass root level first and scale up.

Received: 12 January 2020 Accepted: 6 April 2020 Wastewater containing dyes is a major source of environmental pollution. The purpose of this study is to evaluate the use of celery leaves extract employed to prepare zerovalent Iron nanoparticles (C-nZVFe) as a catalyst in Fenton reaction. The getting nanoparticles are then applied to decolorization aqueous solutions containing orange (OG) dyes. The C-nZVFe catalyst has been characterized by Fourier transformed infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM) techniques for the investigation of structural and surface morphology properties. The size and surface area of synthesized C-nZVFe are observed around 40 -55 nm. Using ultraviolet-visible (UV – vis) spectroscopy, the amount of dye in the aqueous sol is observed. Orange G removal percentage (100 mg L) reached 86% [35 mg L, 60 min, and pH 4]. C-nZVFe nanoparticles demonstrated more efficient percentage capacity as a Fenton catalyst removal and are more economical, efficient, and recyclable than other conventional Fenton oxidation catalysts.


The application of machine learning (ML) provides an exciting opportunity for intelligent product design, and ML also implements new practices under the influence of design. The intelligence of ML, as a type of artificial intelligence (AI), assists designers in extracting features or patterns (Nasrabadi, 2007; Witten et al., 2016) from high-dimensional information, such as information on facial expressions (Yu & Zhang, 2015), image style (Johnson et al., 2016), and body language (Behoora & Tucker, 2015). Simultaneously, demonstrative examples can be provided to enable ML to function without explicitly written rules (Hebron, 2016). Rule-based intelligent products only perform pre-defined responses to specific events in accordance with established rules, but ML-empowered products learn the patterns from the provided data to respond appropriately to various situations, and have the potential to cope with complex situations that could only be previously solved by human intelligence. Furthermore, design thinking, such as human-centered thinking, is gradually changing ML technology so that ML can better serve users (Gillies et al., 2016). For instance, researchers in the field of human-computer interaction (HCI) encourage users to freely edit corrective examples to improve the performance of the ML model (Amershi et al., 2014; Fails & Dan, 2003). Thus, there is an urgent need for designers to learn more about ML and potentially create new ways of empowering products using ML (Dove et al., 2017; Yang, 2017; Yang et al., 2018a). Unfortunately, most designers do not have adequate ML literacy to ideate creatively and practically (Yang, 2017) because ML, compared with traditional technologies, has undergone dramatic transformation and is thus a difficult technology to understand. ML literacy refers to designers (1) understanding the basic concepts of the ML capability, mechanism, and working process; and (2) leveraging or expanding the ML capability so that they can prototype and evaluate design proposals. ML literacy helps designers to become familiar with design material and thus enhances their design abilities to empower products with ML, for example, knowing how to obtain necessary data and computing resources and construct interaction. Moreover, ML literacy ORIGINAL ARTICLE


At present, although the research on learning behavior has made some progress, it is still in infancy. There are still many practical problems need to be solved. For example, how to promote effective learning in class. In the context of big data, this paper proposed a framework to collect and process interaction behavior data in wisdom classroom. First step, collecting and processing the interactive learning behavior data in and after class. Second step, analyzing the interactive learning behavior data. Finally, judging the behavior based on the analysis results. A learning model to form a personalized learning library for students is built in this paper, which performs feedback and guidance for learners' learning activities. Using this framework can achieves individualized or adaptive student learning, and realizes the purpose of promoting effective learning.


The article reports about an international colloquium from 18 th to 20 th October 2012 in Paris, entitled "Understanding the tasks of the forthcoming Council of the Orthodox Church". Presentations by Orthodox theologians from different local Churches gave an overview of the tasks of the Pan-Orthodox Council and ecumenical observers commented on the pivotal themes.


Despite the stimulating effect of measures taken by the central bank, we notice the tendency of stagnation of non-government credit, started in the fourth quarter of 2008. Delayed economic recovery, credit costs still high and the manifestation of a more cautious attitude of banks, and customers, indicated the maintaining of current trends for the year 2011. Therefore, in this paper, we proposed ourselves to analyze the influence of the GDP and interest rate on the non-government credit using the regression function. We will then establish the correlations between these indicators, emphasize the changes that appeared over the years and the measures to be taken in order to improve the loan portfolio quality in the Romanian banking system.


It involves non-intellectual factors and personal factors to change passivity into initiative in college English learning. There are three problems that result in students' passive learning: their obeying and passive acceptance because of the influence from the certain cultural and traditional background, the unbearable studying pressure and its aftereffect, an improper learning aim and the knowledge-oriented focus. This paper comes up with three strategies that bring in students' initiative in learning: reforming examination system and practicing credit system; practicing level-graded instruction and offering selective courses; overall developing students' ability in two instructing environments.


Pearl millet [Pennisetum glaucoma (L.) R. Br.], belongs to family Poaceae (section Paniceae), is the world's hardiest warm-season cereal crop with the annual rainfall of 150 mm to 1000 mm.Maximum mycelial growth was recorded in potato dextrose carrot agar medium (86.33 mm) followed by Pearl millet Potato dextrose agar (83.67 mm), potato dextrose agar (78.33 mm), Pearl millet carrot dextrose agar (71.67 mm), Pearl millet potato agar (68.33 mm), Carrot dextrose agar (60.67 mm), Pearl millet grain potato dextrose agar (58.33 mm), Oat meal agar (51.67 mm), Pearl millet dextrose agar (51.67 mm), Calcium carbonate agar (42.67 mm), Malt agar (41.00 mm), Water agar (37.33 mm), Pearl millet grain dextrose agar (35.33 mm), Pearl millet agar (30.00) and Yeast extract agar (28.33 mm) while minimum growth was recorded in Pearl millet grain agar (27.33 mm).


The skin contains no appreciable vitamin A, 1 in spite of the fact that the latter has an important influence on cutaneous structure and growth. Indeed, all epidermal parts are affected by indirect means through the metabolism of vitamin A. Just how this action is accomplished is not known, but some evidence points to active participation of the liver in the process. The procedure is probably a complex one with at least several repercussions. This surmise is strengthened by the various resulting forms that a single organ such as the skin may show from vitamin A deficiency and dysmetabolism. Thus it has been fairly satisfactorily demonstrated that vitamin A metabolism in some way or another is associated with such diverse morphologic forms as Darier's 2 and Devergie's 3 diseases as well as xeroderma and certain forms of lichen spinulosus. Balbi 4 found that generalized cutaneous eruptions


The author discusses the class of fully implicit one-step methods of any order for the numerical solution of neutral functional-differential equations. For judicious choices of the parameters these methods are NP-stable, which means that the numerical approximation to the solution Y of the linear test equation y'=ay(t)+by(t-d) +cy'(t-d), t>or=0, is bounded whenever Y is bounded. This property is an analogue of A-stability of ordinary differential equations. The local discretization error of these methods can be estimated by comparing two approximations of successive orders. This can be done in a very efficient way, and these methods can be implemented in variable-step mode with a step-changing strategy based on this estimate. Numerical results are presented that illustrate the high potential of fully implicit formulas.<<ETX>>


Hepatocellular carcinoma (HCC) is a major health problem, with more than 500,000 cases diagnosed annually. It is also an important cause of human mortality in the world. The incidence of HCC is rising due to the widespread of hepatitis and alcoholism, which may be caused by infection, injury, exposure to drugs or toxic compounds, autoimmunity, or genetic defect that leads to the deposition of harmful substances.[1]


The kinetics of glucose limited growth by a marine yeast, shown to be a Rhodotorula species, have been studied in a continuous culture apparatus. The saturation constant, in synthetic media, has been calculated to be 0 .2 5 mg/i» on the assumption that saturation kinetics are follotred, The maximum growth rate was determined in both synthetic media, and artificial sea water. On the basis of inhibition kinetics, the kinetic behavior of this yeast in the marine environment has been predicted. The effect of temperature on the maximum growth rate has been determined and, on the assumption of a similar effect on the saturation constant, the saturation constant has been postulated to be in agreement with similar values determined for other microorganisms.

This work presents an interlaboratory study (ILS) resulting in a precision and bias statement for AASHTO T283, "Resistance of Compacted Hot Mix Asphalt (HMA) to Moisture-Induced Damage." To gain insight into the variability of the T283 test results, a micro-scale finite element analysis using X-ray images of the test specimens was conducted. The ILS included preparing and testing 6 replicate specimens according to AASHTO T283 using two different aggregate sources and two compaction methods. The two aggregate sources were selected based on their moisture susceptibility. A sandstone aggregate representing moisture susceptible and a limestone aggregate representing moisture resistance were selected for the study. Marshall and Superpave gyratory compactors were selected as means of compaction to create test specimens with different structures. The statistical analysis of the ILS results indicated that the average tensile strength ratios (TSR) of the Marshall and gyratory specimens and that of limestone and sandstone mixtures were significantly different. Despite the difference in the average TSR values, the variability of TSR of Marshall and gyratory compacted specimens of limestone and sandstone mixtures were not significantly different. In this respect, the TSR statistics of the four specimen types (two mixture types and two compaction methods) were combined to prepare the precision estimates for AASHTO T283. The simulation of moisture infiltration in the X-ray images of gyratory and compacted specimens indicated that moisture penetrates to the center of Marshall specimens much faster than to the center of gyratory specimens. The reason for this was found to be the difference in size and distribution of outside and inside pore spaces in gyratory and Marshall specimens. Additionally, the conditioning procedure, as described in the current T-283 standard was found to not represent the actual moisture infiltration time frame that produced damage in the field. This could explain the often encountered discrepancy between laboratory and field moisture performance.


"If one is afraid of robbers in a dream, the robbers, it is true, are imaginary but the fear is real," notes Freud in The Interpretation of Dreams} The content of an oneiric message can be transformed, adorned with makeup, or mutilated, but not its affective dimension, its thymic component. Affect sticks to subjectivity, it is a glischroid matter, to pick up a qualifier used by Minkowski to describe epilepsy.2 Only, an affect sticks just as well to the subjectivity of the one who is its utterer as it does to the one who is its addressee; and, in so doing, it disqualifies the enunciative dichotomy between speaker and listener. Spinoza perfectly pinpoints this transitivist character of affect ("from the fact of conceiving a thing like ourselves to be affected with any emotion, we are ourselves affected with a like emotion") and from which results what he calls "an emulation of desire" and the deployment of multi-polar affective compositions. Thus, the sadness we feel through the sadness of another becomes commiseration, while "he who conceives another as affected with hatred, will thereupon be affected himself with hatred; he who hates a man will endeavor to remove or destroy him."3 Affect is thus essentially a pre-personal category, installed "before" the circumscription of identities, and manifested by unlocatable transferences, unlocatable with regard to their origin as well as with regard to their destination. Somewhere, there is hatred, in the same way that, in animist societies, beneficent or nocuous influences circulate through the spirit of ancestors, and, concurrently, of totemic animals, or through the "mana" of a consecrated place, the power of a ritual tattooing, a ceremonial dance, the recount-


OBJECTIVES
To investigate the contribution of Doppler-echocardiographically derived aortic indexes of left ventricular systolic function during dipyridamole-stress to the diagnosis of coronary artery disease (CAD).

DESIGN
This was a clinical study.

METHODS
Echocardiographic studies under baseline and peak dipyridamole stresses were performed on 15 normal subjects and 32 patients with angiographically confirmed CAD. Peak Doppler velocity, acceleration, and acceleration time of the ascending aorta, as well as segmental left ventricular wall motion, were analyzed.

RESULTS
The sensitivity, specificity and overall accuracy of wall-motion abnormalities induced by dipyridamole for the detection of CAD were 62.5, 100, and 74.5%, respectively. When wall-motion abnormalities were combined with the percentage changes in peak aortic velocity and acceleration, the overall sensitivities were 84.38 and 78.15%, respectively, the specificities were 66.7 and 80.00%, respectively, and the accuracy was 78.72% for both models. When all three parameters were combined, the sensitivity, specificity and overall accuracy of the method were 87.5, 86.7, and 87.2%, respectively.

CONCLUSIONS
Doppler-echocardiographically derived aortic indexes of left ventricular systolic function during dipyridamole stress could be a useful adjunct to two-dimensional echocardiography by improving its sensitivity in the diagnosis of CAD.


The study focuses on chemical composition of stream and subsurface water in the catchments of two small arctic alpine lakes in the Kilpisjärvi area (northwest Finland). Differences and changes in chemical components of both water types are followed in order to detect spatial variability and impact of environmental factors. To achieve this, ion compositions of subsurface water and streams were measured at 12 sites in the catchments of Lakes Saana and Saanalampi during four years (2008–2010, and again in 2017). In the Lake Saanalampi catchment, the salinity of stream water (7.0 to 12.7 μS·cm−1) corresponded to that of snow. In the catchment of Lake Saana, however, the conductivity in stream water was much higher (40 to 220 μS·cm−1), connected mainly to the increase of SO42− and less with Mg2+ and Ca2+ contents, especially in the western part of the Saana catchment. These results demonstrate that arctic conditions do not preclude intense chemical weathering where conditions are favourable. Although chemical composition of the soil fluid does not match the geochemical signal from the local soil, rock composition, especially the presence of pyrite, is the main controller of chemical weathering rates of the rocks on the area. This supports earlier views that the character of precipitation mostly controls water chemistry of local lakes in the Kilpisjärvi area.


4676 Background: The use of androgen deprivation therapy (ADT) in prostate cancer is associated with increased fracture risk. Previously we demonstrated in a phase III trial that toremifene, a selective estrogen receptor modulator (SERM), significantly decreased fracture incidence in men receiving ADT. Similar to other SERMs, there was an increase in venous thromboembolic events. This risk appeared to stratify to men ≥80 years of age. VTEs occurred in 1.5% and 2.5% of men <80, ≥80 respectively. To identify a patient population with the greatest benefit/risk profile we assessed the effect of toremifene in men <80 years. Methods: In this analysis of men <80 years of age receiving ADT for prostate cancer, 430 men received toremifene 80 mg and 417 received placebo (orally daily). All subjects were on ADT for ≥ 6 months, had a serum PSA ≤4 ng/mL, were ≥70 years of age or were at or below WHO thresholds for spine or hip (BMD). The primary endpoint was new vertebral fractures. Secondary endpoints included fragil...


One-year data from the randomized SHOCK trial, which enrolled 302 MI patients with cardiogenic shock, showed a significant advantage of early


In nearly a hundred years of construction, underground gas storage has become the main natural gas storage and peak regulation means in the world. For the gas storage, the large production and high flow rate of the gas well in the actual production process will cause the backflow of proppant filled in the supporting fracture, which will bring great harm to the gas field production. In this article, when the proppant fracture reaches a stable state in the process of gas injection and production, the stress of proppant particles is analyzed, the critical velocity of proppant reflux is calculated, and then the critical production model is established; calculate the permeability change during proppant migration, then calculate the fluid velocity and production, and determine the fluid velocity range of injection and production wells in gas storage. The parameter sensitivity of velocity and flow model is analyzed. The results show that with the increase of closure stress, the critical gas flow and critical gas velocity of proppant backflow gradually increase, and the proppant filling layer is more stable. The smaller the thickness and width of the filling layer, the greater the critical gas flow and critical gas velocity of proppant backflow, the more stable the proppant filling layer, and the lesser the chance of backflow. The higher the saturation, the lower the critical gas velocity, and the more prone the proppant to reflux. It has important guiding significance for realizing the optimization of gas well production and maintaining efficient production efficiency.


: The current research study explores the suffering of double consciousness in the character of Parizaad in Pakistani Urdu drama serial, Parizaad. It is a story which unfolds Marxist, racist and sociological themes. However, the researcher has utilized a non-empirical Textual Analysis Method of research along with following the concept of double consciousness by Du Bois as a theoretical framework for analyzing the drama serial to explore the research objective. The framework argues that black people are behaved racially which causes inferiority complex, second-sight and twoness in them. Similarly, the analysis of the drama serial in this research study manifested that Pakistani brown people, following white legacy of racism, consider themselves superior to their fellow blackish people. Also, the power of money is dominant, and such socio-economic factors cause double consciousness in the character of blackish-skin Parizaad.


The compound Sr14Cu24O41 has a unique structure. It consists of an alternating stack of the plane containing edge-sharing CuO2 chains, and the plane containing two-leg Cu2O3 ladders sandwiched by Sr layers. The CuO2 chain also has a singlet ground state originating from a dimerization. The dimerized state in the chain depends critically on the number of holes. The effect of La substitution for Sr on the CuO2 chain spin gap is investigated by measuring the magnetic susceptibility of Sr14−xLaxCu24O41 with x⩽1. Due to the large spin gap, the Cu2O3 plane is magnetically inert below room temperature. For x=0, the susceptibility shows a characteristic decrease below 80 K, followed by an upturn below 20 K due to a Curie contribution. After subtracting the Curie term, the susceptibility is fitted by a dimer description. The dimer number ND=1.45 and the dimer coupling constant JD=139 K are obtained. With increasing La content, both ND and JD decrease gradually, indicating the weakening of the antiferromagnetic int...


Studies with both rats and humans show that Selective Serotonin Reuptake Inhibitors (SSRIs) lead to a short term reduction in alcohol consumption (AC); however, AC returns to at least baseline levels at the end of one week in humans. The SSRI fluoxetine (Prozac) shows significantly better results than placebo in reducing both AC and depression in Alcohol Dependent subjects with comorbid severe Major Depressive Disorder. However, SSRIs are not better than and may be worse than placebo in reducing AC in individuals who do not suffer from severe Major Depressive Disorder. In subjects who lack major depressive disorder it appears that SSRIs significantly interfere with the impact of psychosocial therapy on the AC of both women and individuals with Early Onset Alcohol Use Disorder (AUD). I. e. women and individuals with Early Onset AUD who received an SSRI and psychosocial therapy for drinking showed significantly less reduction in AC than did subjects who received a placebo and psychosocial therapy. This suggests that SSRIs might potentially increase AC in women and in individuals with Early Onset AUD who do not receive any psychosocial therapy for their drinking. Further research is called for to confirm this hypothesis.


The failures of mining tailings dams in Mariana, in 2015, and in Brumadinho, in 2019, are identified as the biggest environmental disaster and the biggest work accident in the history of Brazil, respectively. This article aimed to analyze the background of these tragedies, their environmental and socioeconomic impacts, as well as the psychosocial consequences for the population directly and indirectly affected by these tragedies. The method used was the integrative literature review. Searches for scientific articles were carried out in the SciELO, PePSIC and BVS Salud BIREME databases, using the following combination of descriptors: "Brumadinho" & "desastre" and "Mariana" & "desastre". Fourteen articles were analyzed, published between 2015 and 2020. The results show the weaknesses of the State in the prevention, resolution, and accountability of such crimes, demarcating a history of impunity for the companies involved, lack of reparation for socio-environmental damage, and helplessness to the affected population. Furthermore, the role of emergency and disaster psychology in these scenarios was analyzed, highlighting the ethical commitment of this profession to the promotion of mental health and the guarantee of rights.

The advances in the automotive industry with the ever-increasing request for Connected and Autonomous Vehicles (CAVs) are pushing for a new epoch of networked wireless systems. Vehicular communications, or Vehicle-to-Everything (V2X), are expected to be among the main actors of the future beyond 5G and 6G networks. However, the challenging application requirements, the fast variability of the vehicular environment, and the harsh propagation conditions of high frequencies call for sophisticated control mechanisms to ensure the success of such a disruptive technology. While traditional Radio Access Networks (RAN) lack the flexibility to support the required control primitives, the emergent concept of Open RAN (O-RAN) appears as an ideal enabler of V2X communication orchestration. However, how to effectively integrate the two ecosystems is still an open issue. In this position paper, we discuss possible integration strategies, highlighting the challenges and opportunities of leveraging O-RAN to enable real-time V2X control. Additionally, we enrich our discussion with potential research directions stemming from the current state-of-the-art and we give an overview of the simulation tools that can be employed to facilitate investigations on this topic


In modern times a long-established system of Judaism formed in ancient days—a world view, way of life, addressed to a distinctive Israel, framed in response to urgent and perennial questions—lost its paramount position. That received Judaic system gave way to new Judaisms—that is, Judaic systems, each with its own set of selfevidently true answers to ineluctable questions. Each of these systems in its way claimed to take the natural next step in "Jewish history," or in the "tradition" or to constitute the increment of Judaism (the tradition) in its unfolding, linear history. All of them were wrong, and, in erring gloriously in perfect self-delusion, each one has testified to the powerful imagination of humanity, to the courage of people to face urgent questions and to compose, in solving them, systems of belief and behavior capable of creating whole worlds of meaning: sensibility and sense alike.


Let X and Y be metric continua. Let Fn(X) (resp., Fn(Y)) be the hyperspace of nonempty closed subsets of X (resp., Y) which contain at most n elements. We say that the hyperspace Fn(X) can be orderly embedded in Fm(Y) provided that there exists an embedding h from Fn(X) to Fm(Y) such that if A,B are elements of Fn(X) and A is contained in B, then h(A) is contained in h(B). In this paper we prove:
(a) If n is minor or equal than m, m is minor than 2n and Fn(X) can be orderly embedded in Fm(Y), then X can be embedded in Y.
(b) There exist continua X and Y such that, for each n greater than 1, Fn(X) can be orderly embedded in F2n(Y) and X can not be embedded in Y


Gait analysis is an important tool to measure function following total knee replacement. It is currently unknown whether there is a correlation between subjective and objective outcome variables. The purpose of this study was to analyse relationships between subjective outcome scores and kinematic and kinetic data.25 consecutive patients (15 males, 10 females) were selected (mean age 68 years, BMI 31.8). All subjects were tested a minimum of 24 months following total knee replacement. SF12, Oxford knee score, knee society and KOOS scores were collected. Muscle strength was assessed using a Biodex dynamometer and symmetry indices were analysed. A timed up and go test and KT2000 measurements were performed.Strong correlations (r=0.52–0.74) were found between scoring systems (SF 12, Oxford knee score, knee society score, KOOS score) and the timed up and go test. Moderate correlations (r=0.27–0.35) were found between knee scores and KT2000 measurements. Only weak correlations (r=0.09–0.12) were found between ...


A formal proof is given that in a seesaw type neutrino mass matrix with only two neutrino mass scales ${(m}_{D}\ensuremath{\ll}{m}_{R})$ we cannot get a fourth light sterile neutrino. That is, it is not possible to impose any symmetries on ${m}_{D}$ and/or ${m}_{R}$ matrices in order to drag a heavy state connected with the ${m}_{R}$ matrix to the low mass spectrum.


Background and Aim:  Although percutaneous endoscopic gastrostomy (PEG) has become established as a useful enteral nutrition technique, the associated risks must always be kept in mind. Recently, we experienced several patients who could orally ingest after PEG. To avoid unnecessary PEG, we investigated patients who could orally ingest after PEG, and analyzed predictive factors of postoperative oral feeding.


Simple Summary Triple-negative breast cancer (TNBC) has a high recurrence rate and metastasis rate, and the prognosis for patients is poor. Identifying novel treatment avenues for TNBC is crucial for the treatment and prognosis of TNBC patients. Deubiquitinase deficiency is associated with the occurrence and progression of several diseases, including cancer. As a member of deubiquitinase, ubiquitin-specific peptidase 53 (USP53) is essential for the development of tumors such as hepatocellular carcinoma and renal clear cell carcinoma. However, the precise function of USP53 in TNBC remains unknown. Our study has identified USP53 as a molecular target that mediates the progression of TNBC. This not only deepens our understanding of the tumorigenesis and development of TNBC, but also provides new potential therapeutic targets for TNBC patients. Abstract Breast cancer (BC) ranks in the top five malignant tumors in terms of morbidity and mortality rates. Among BC subtypes, TNBC has a high recurrence rate and metastasis rate and the worst prognosis. However, the exact mechanism by which TNBC develops is unclear. Here, we show that the deubiquitinase USP53 contributes to tumor growth and metastasis in TNBC. USP53 is overexpressed in TNBC, and this phenotype is linked to a poor prognosis. Functionally, USP53 promotes TNBC cell proliferation, migration, invasion, and epithelial–mesenchymal transition (EMT). More importantly, USP53 decreases the chemosensitivity of BC cells by enhancing v-crk sarcoma virus CT10 oncogene homologue (avian)-like (CRKL) expression. Mechanistically, USP53 directly binds CRKL to stabilize and deubiquitinate it, thereby preventing CRKL degradation. Overall, we discovered that USP53 deubiquitinates CRKL, encourages tumor development and metastasis, and reduces chemosensitivity in TNBC. These findings imply that USP53 might represent a new therapeutic target for the treatment of TNBC.


Mastic has a significant effect on the properties of bituminous mixtures and acts as a real binder. It determines the resistance of the asphalt mixture to the formation of plastic deformation, the sensitivity to the effects of water and the low temperature cracking as well. In the article, advanced rheological research using the mastic with virgin bitumen 50/70 was presented. Mastic has been enriched by addition of the hydrated lime together with synthetic wax modified bitumen. The experiment design was based on the Box-Behnken plan. This experiment plan consisted of three controlled factors: the amount of synthetic wax, the amount of hydrated lime and the amount of filler in the asphalt mastic composition. The work highlights the interaction between synthetic wax and the amount of hydrated lime. The assessment of the influence of controlled factors was determined within the viscoelastic region performed by means of a dynamic shear rheometer. The experiment used the determination of viscoelastic properties of the mastic, i.e. complex dynamic viscosity η *, dynamic shear modulus G*, phase shift angle δ at temperatures 40 °C, 60 °C and 80 °C. In addition, the influence of controlled factors was determined using MSCR tests in the 100 Pa and 3200 Pa range. As a result, creep compliance and elastic recovery were determined at 60 °C. The tests showed a diversified increase in the stiffness of the asphalt mastic with wax and hydrated lime additive, at given high test temperatures, in relation to the mastic with a traditional filler. It should be noted that the presence of crystallites of a synthetic wax also caused a significant increase in the stiffness of the mastic.


The effects of the temperature and the asphalt-aggregate ration on splitting characteristics of AC-13 grading and AC-16 grading asphalt mixtures were investigated in the laboratory combining with the climate feature of low annual mean temperature and large temperature difference in Qinghai-Tibet Plateau.The results show that the splitting strength and stiffness of AC-16 grading was larger than AC-13 grading,and when temperature is lower,it is more significant advantage.


History has many gaps that researchers are slowly trying to fill. However, there will always be dark spots. One of them is the ostentation of the position of Patriarch of the West Indies between the resignation of Antonio Allue Sese and the appointment of Manuel Fraile Garcia. The history of the West Indies Patriarchate and the life of Don Jose Duaso y Latre, the canon who is believed to have held the position of Patriarch for eight months, will be discussed.


The absorption spectra induced in neat liquid ammonia and ammoniacal solution of N/sub 2/O by nanosecond pulse radiolysis have been measured for wavelength range 250 to 325 nm. The results indicate that the absorption spectrum induced in liquid ammonia is a composite of absorption spectra of e/sub am//sup -/ and NH/sub 2/. The absorptions due to e/sub am//sup -/ decrease with decreasing wavelength, and are attributed to the tail of the absorption spectrum (maximum absorption in near infrared) of e/sub am//sup -/. The absorption spectrum for NH/sub 2/ has a shoulder at approximately 255 nm. In liquid ammonia at 23/sup 0/C, the extinction coefficient for NH/sub 2/ at 250 nm is 1.1 x 10/sup 3/ M/sup -1/ cm/sup -1/.

Stochastic volatility (SV) models provide a means of tracking and forecasting the variance of financial asset returns. While SV models have a number of theoretical advantages over competing variance modelling procedures they are notoriously difficult to estimate. The distinguishing feature of the SV estimation literature is that those algorithms that provide accurate parameter estimates are conceptually demanding and require a significant amount of computational resources to implement. Furthermore, although a significant number of distinct SV specifications exist, little attention has been paid to how one would choose the appropriate specification for a given data series. Motivated by these facts, a likelihood based joint estimation and specification testing procedure for SV models is introduced that significantly overcomes the operational issues surrounding existing estimators.

The estimation and specification testing procedures in this thesis are made possible by the introduction of a discrete nonlinear filtering (DNF) algorithm. This procedure uses the nonlinear filtering set of equations to provide maximum likelihood estimates for the general class of nonlinear latent variable problems which includes the SV model class. The DNF algorithm provides a fast and accurate implementation of the nonlinear filtering equations by treating the continuously valued state-variable as if it were a discrete Markov variable with a large number of states. When the DNF procedure is applied to the standard SV model, very accurate parameter estimates are obtained. Since the accuracy of the DNF is comparable to other procedures, its advantages are seen as ease and speed of implementation and the provision of online filtering (prediction) of variance. Additionally, the DNF procedure is very flexible and can be used for any dynamic latent variable problem with closed form likelihood and transition functions. Likelihood based specification testing for non-nested SV specifications is undertaken by formulating and estimating an encompassing model that nests two competing SV models. Likelihood ratio statistics are then used to make judgements regarding the optimal SV specification. The proposed framework is applied to SV models that incorporate either extreme returns or asymmetries.

Medulloblastoma (MB) is a malignant pediatric brain tumor with poor prognosis. Signal transducers and activators of transcription‐3 (STAT3) is constitutively activated in MB where it functions as an oncoprotein, mediating cancer progression and metastasis. Here, we have delineated the functional role of activated STAT3 in MB, by using a cell permeable STAT3‐NH2 terminal domain inhibitor (S3‐NTDi) that specifically perturbs the structure/function of STAT3. We have implemented several biochemical experiments using human MB tumor microarray (TMA) and pediatric MB cell lines, derived from high‐risk SHH‐TP53‐mutated and MYC‐amplified Non‐WNT/SHH tumors. Treatment of MB cells with S3‐NTDi leads to growth inhibition, cell cycle arrest, and apoptosis. S3‐NTDi downregulated expression of STAT3 target genes, delayed migration of MB cells, attenuated epithelial‐mesenchymal transition (EMT) marker expressions and reduced cancer stem‐cell associated protein expressions in MB‐spheres. To elucidate mechanisms, we showed that S3‐NTDi induce expression of pro‐apoptotic gene, C/EBP‐homologous protein (CHOP), and decrease association of STAT3 to the proximal promoter of CCND1 and BCL2. Of note, S3‐NTDi downregulated microRNA‐21, which in turn, de‐repressed Protein Inhibitor of Activated STAT3 (PIAS3), a negative regulator of STAT3 signaling pathway. Furthermore, combination therapy with S3‐NTDi and cisplatin significantly decreased highly aggressive MYC‐amplified MB cell growth and induced apoptosis by downregulating STAT3 regulated proliferation and anti‐apoptotic gene expression. Together, our results revealed an important role of STAT3 in regulating MB pathogenesis. Disruption of this pathway with S3‐NTDi, therefore, may serves as a promising candidate for targeted MB therapy by enhancing chemosensitivity of MB cells and potentially improving outcomes in high‐risk patients.


HAPTICS is a field of study that deals with perceiving, transmitting, and reproducing human haptic sense. Auditory and visual sensations are unilateral, whereas haptic sensation is bilateral via the principle of action and reaction. Haptic technologies have been applied, with ever increasing potential, in manufacturing, medicine, entertainment, and defense. With the advent of new functional materials, smart actuators and sensors, embedded computers, and the latest advance in real-time intelligence, machine learning, cognitive science, and augmented reality/virtual reality/mixed reality, a lot of more novel, intelligent, user-friendly haptic devices are emerging. At the core of these devices are essentially the sensor that perceives remote contact with real world in various physical forms, the transmission that transfers remote contact sensation to haptic interface, the actuation that reproduces the haptic sense perceivable by a human operator and the bilateral control that closes the loop of haptic feedback. Due to the small size requirement for wearable devices, the many degrees of freedom from the use of soft, stretchable sensors and actuators, the embodiment of actuators, sensors and controllers and the level of intelligence, speed, precision or compliance required, unique challenges emerge concerning the design and realization of novel haptic interaction and teleoperation. IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS has published a considerable amount of works on haptics in recent decades, in parallel to the IEEE TRANSACTIONS ON HAPTICS and other journals with varying scopes. So far, no journal has devoted yet a special issue or special section to novel emerging sensing, actuation, and control techniques for haptic interaction and teleoperation. Indeed, there have been other journals publishing various special issues on the haptics related themes; however, almost all of them were on the novel applications of haptics rather than the technologies enabling haptics. Those published special issues were intended to promote more applications of haptics. Novel sensing, actuation, and control methods and technologies that enable haptics are the themes of this special section. The call for papers was well responded. A total of 48 submissions were received and 20 papers were finally accepted after a rigorous peer reviewing process. The special section has a collection of five, seven, and eight papers in sensing, actuation, and control, respectively.

Synopsis Phase separation by suspension copolymerization of styrendivinylbenzene (DVB) with di2-ethylhexyl phthalate (DOP) as diluent was investigated using equilibrium swelling, swelling rate, apparent densities, and mercury porosimetry. The copolymer prepared in the absence of DOP is heterogeneous, showing that a phase separation exists in the polymerization system, and, in the presence of DOP, the propagating copolymer separates earlier. Furthermore, with increasing amounts of DVB, phase separation occurs earlier than gelation, which causes a sudden increase in the amount of pores about 200500 A in diameter corresponding to the interstices between the microspheres.

In comparison to heterosexual counterparts, sexual minority student-athletes are two times more likely to experience harassment, more negative climates, report feeling deliberately ignored or excluded from team actives and are subjected to orientation-based derogatory marks via electronic means (Rankin & Merson, 2012). This particular population is 2-3 times more likely to experience anxiety and depression, nearly 14% will attempt suicide or acts of self-harm, and are more likely to abuse drugs and alcohol (Cunningham, 2015). Non-inclusive climates negatively affect academic and athletic performance (Wolf-Wendel, Bajaj, & Spriggs, 2008; Turk, & Stokowski, 2016; Cunningham, 2015). The Athletic Equality Index (AEI) measures LGBTQ inclusion policies and practices in Power 5 conference athletic spaces. University fails to adequately meet 80% of the AEI criteria: non-discrimination policies, out or allied staff, accessible resources, collaboration with campus group(s), LGBTQ student-athlete group or initiative, pro LGBTQ equality campaign/statement, LGBTQ inclusive fan code of conduct, and guidelines for transgender inclusion (Athlete Ally, 2017). The AEI provides a tangible source of inclusion but does not measure daily efforts, or lack thereof, to foster inclusive environment for student-athletes. The NCAA recommends athletic departments offer support by developing inclusive policies, implementing educational initiatives and providing recourses to support LGBTQ student-athletes but these recommendations are unregulated and athletic departments ultimately determine the resources provided. Informed by Brewer's (1991) model for Optimal Distinctiveness Theory (ODT), the purpose of this case study is to understand and describe inclusion of student-athletes who identify as sexual minority within an NCAA Division I athletic department. This study strives to answer the following research questions concerning inclusion of student-athletes who identify as sexual minority at an NCAA Division I institution: (1) How does University athletic department address the issue of inclusion? (2) How do student-athletes experience inclusion within University? Data collection includes: document review, semistructured interviews, and reflexive journaling. This study explores the climate of inclusion for sexual minorities and how the athletic departments may better serve this particular population. Exploring and understanding athletic departments' role in inclusion is crucial in the development, construction, and preservation of inclusion within NCAA Division I member institutions.


The results from the thermal cracking of unhydrogenated and hydrogenated coal-derived materials, a gas condensate and model compounds led to the conclusions that: (1) only low (< 3.5%) BTX and ethylene yields were obtained by cracking the vapours from a bituminous coal, an anthracene oil and the anthracene oil extract of the coal; (2) the BTX and ethylene yields increased with increasing extent of hydrogenation of the extract (which increased the naphthene content); tar was mainly derived from the aromatic and hydroaromatic components; (3) about 27% BTX ald 24% ethylene were obtained from the highly hydrogenated coal extract; in comparison, a paraffinic North Sea gas condensate gave 16% BTX and 30% ethylene; (4) the product yields from mixtures of model compounds were predicted to within +-2% from those of the constituents. The model compound studies confirmed that the molecular structure of the hydrogenated coal extract is of paramount importance in determining the product pattern: hydroaromatics dehydrogenate to aromatics, which either survive or polymerize to tars and, eventually, to carbon; naphthenes crack principally to BTX and ethylene; aliphatics mainly give small unsaturates such as ethylene and butadiene. The abnormally low yield of BTX from the mesitylene is attributed to its highmore » symmetry and thermal stability.« less


Herein we describe a rare case of acute appendicitis associated with localized aspergillosis in an 8-year-old boy with acute lymphoblastic leukemia. During chemotherapy, the patient complained of mild abdominal pain in the peri-umbilical area and displayed an increased Creactive protein level. Abdominal ultrasonography disclosed appendicitis and consequently an appendectomy was done. Histologically, acute appendicitis and Aspergillus hyphae were identified in the lumen and necrotic mucosa. However, there was no evidence of systemic aspergillosis. While aspergillosis is a common fungal infection in immunocompromised patients treated with chemotherapy, acute appendicitis associated with localized aspergillosis without systemic infection is a very rare occurrence.


Despite the recent research efforts into the antecedents of organizational commitment most especially in the developed economies, little empirical work has been conducted examining the effect of some human resource management practices such as performance appraisal system, career planning system and employee participation on organizational commitment. In this article, we examined the effect of these human resource management practices in explaining employee job commitment in the Nigerian banking sector. Based on a survey of 14 banks in Nigeria, the study applies regression analysis, correlation analysis and G-test in testing the hypotheses. Results indicate that performance appraisal system, career planning system and employee participation significantly influence employee job commitment and that the level of organizational commitment of employees in the Nigerian banking sector is low. The study therefore, recommends that for employees to be genuinely committed to their jobs, organizations should make conscious efforts at strategically managing performance appraisal, career planning and employee participation with a view to ensuring effective implementation and achieving desired results.

The rates of the reactions of CH4 with T2 to give, successively, CH3T, CH2T2, CHT3, and CT4, and of the reverse reactions of the tritiated molecules with protium were measured. Second‐order rate constants were obtained from the data, and radiation yields were determined. The reactions were shown to follow two paths. Beta decay energy deposited in the tritium resulted in an exchange reaction in which approximately one exchange took place per ion pair formed. Energy initially deposited in the methane resulted in six exchanges per ion pair. Equilibrium constants were calculated from the steady‐state concentrations and were shown to be close to the high‐temperature, classical values. Hot atom, ion, and radical reactions are believed to play a predominant role in the exchange.


Abstract An eversible endophallus is present in most groups of bees. Its presence or absence and its morphological variation were studied in 122 species, representing nine families of bees. An eversible endophallus is absent in the sphecoid wasps and other aculeate Hymenoptera, as well as in the bee families Colletidae and Oxaeidae, and part of the subfamily Andreninae of the Andrenidae. It is suggested that the families Colletidae and Oxaeidae may represent early offshoots in bee phylogeny. Extremely complex endophalli occur in some groups of bees: a positive correlation between complex endophalli and polyandrous mating system was found, suggesting that sexual selection may be the evolutionary force shaping endophallic morphology. The function of the endophallus, as well as of other parts of the external genitalia, was studied in specimens in copula of Nomia nevadensis and Perdita albipennis. The study of the mechanics of copulation was extended to other species, showing that the several sclerotized part...


When the new ship orders decline deeply and the shipbuilding capability is releasing quickly, how to guarantee the accuracy of prediction of new ship orders becomes the main target for shipbuilding corporate. This paper aims to predict the future demand of new ship with the help of combination forecast model that consist of grey system, support vector machine and artificial neural network. The result showed that combination forecast method is better than single usage of other three methods. The prediction result of new ship orders could provide some useful reference for the development of the shipbuilding industry.


This study was undertaken with a view of establishing whether there exist any relationship between the Earnings Per Share and Dividend Per Share of equities for companies quoted on the Nairobi Stock Exchange; for the years from 2000 to 2004. Data extracted from published financial statements and published in the NSE Handbook 4th Edition and was analyzed using SPSS with focus on regression model and was presented using tables, graphs and charts. The findings of the study reveal that there is a significant relationship between Earnings Per Share and Dividend Per Share. The findings also reveal that the relationship between the two variables is significant. This is in line with the expectations that dividends must be paid out of company earnings. Of interest is the fact that whereas the Agricultural sector, Commercial and Service sector, Industrial and Allied sector and the Alternative Investment Market of the market report a positive relationship between the Dividend Per Share and Earnings Per Share the Finance and Investment sector report a negative relationship between the two variables. The exception in the later may be explained by the fact that the sector may occasionally be paying dividends out of past earrings.

Over 75% of the major world crops and 80% of all flowering plant species rely on animal pollinators. Of the hundred or so animal-pollinated crops which make up most of the world's food supply, 15% are pollinated by domestic bees, while at least 80% are pollinated by wild bee species and other wildlife. Most of the 25, 000 to 30, 000 species of bees are effective pollinators, and together with moths, flies, wasps, beetles and butterflies, make up the majority of pollinating species. Vertebrate pollinators include bats, non-flying mammals (several species of monkey, rodents, lemur and tree squirrels etc.) and birds (humming birds, sun birds, honey creepers and some parrot species). Current understanding of pollination process shows that, while an interesting specialized relationship exist between plants and their pollinators, healthy pollination services are best ensured by an abundant diversity of pollinators. Thus, pollinators are essential for diet diversity, biodiversity, and maintenance of natural resources. Pollinators which evolved over million of years, are eroding at a fast rate from the globe. During the past few years, many pollinators especially honey bees have been dying across the globe in unprecedented number and, no one has so far been able to prove beyond a reasonable doubt what the causes may have been. The economic implications of these deaths are immediate because honey bees are integral to the pollination of tens of millions of dollars of cash crops in the world. Despite much of the world's agriculture relying on pollination by honeybees, especially European honeybees, their number across the globe has also declined. Many other pollinators such as digger bees, sweat bees, alkali bees, squash bees, leafcutter bees, carpenter bees, mason bees, and shaggy fuzzy foot bees could also be on decline, but data providing unambiguous documentation of trends are simply not available. Threats to pollinators and the services they provide are perceived to be increasing around the world and are mainly man-made in origin. Climate change could be a major factor in weakening the bees and has affected the pollination of crops in many agricultural areas. An attempt has been made to know the causes behind the decline of pollinators, especially in relation to climate change, their conservation and management and impact of declining pollinator population on horticulture in the changed global scenario.


At the end of 2012, Drago Orlic presented his translation of the biblical Book of Job: Libar od Joba (Orlic, 2012) into "Istrian-Chakavian" to the public, of which there is a mention on the book cover. This paper offers an analysis of the Chakavian idiom of Orlic's translation on the phonological and morphological levels. The poetic language of the translation is observed in the context of the linguistic features  of the Southwest Istrian dialect group (to which the local dialect of the author's home village of Mandelici belongs) and of the local dialect of Svetvincenat (the centre of the municipality which comprises the village of Mandelici). It has been concluded that the language of Orlic's translation contains features of the SW Istrian dialect group and of the local dialect of Svetvincenat, including the peculiar areal features: the shift of the initial pretonic o to u, loss of the initial pretonic u (including  the u < o) and v-prothesis. In the plural paradigm of nouns of all three genders, a negligible influence of Standard Croatian has been noted.


(1930) here is a fact which from all the evidence is an integral part of moral action which has not received the attention it deserves in moral theory: that is the element of uncertainty and of conflict in any situation which can properly be called moral. The conventional attitude sees in that situation only a conflict of good and of evil; in such a conflict, it is asserted, there should not be any uncertainty. The moral agent knows good as good and evil as evil and chooses one or the other according to the knowledge he has of it. I will not stop to discuss whether this traditional view can be sustained in certain cases; it is enough to say that it is not right in a great number of cases. The more conscientious the agent is and the more care he expends on the moral quality of his acts, the more he is aware of the complexity of this problem of discovering what is good; he hesitates among ends, all of which are good in some measure, among duties which obligate him for some reason. Only after the event, and then by chance, does one of the alternatives seem simply good morally or bad morally. And if we take the case of a person commonly considered immoral, we know that he does not take the trouble of justifying his acts, even the criminal ones; he makes no effort, to use the psychoanalysts' term, to "rationalize" them. As I just proposed, this problematical character of moral situations, this preliminary uncertainty in considering the moral quality of an act to be performed, is not recognized by current moral theory. The reason for that is, it seems to me, quite Simple. Whatever may be the differences which separate moral theories, all postulate one single principle as an explanation of moral life. Under such conditions, it is not possible to have either uncertainty or conflict: morally speaking, the conflict is only specious and apparent. Conflict is, in effect, between good and evil, justice and injustice, duty and caprice, virtue and vice, and is not an inherent part of the good, the obligatory, the virtuous. Intellectually and morally, distinctions are given in advance; from such a point of view, conflict is in the nature of things, a hesitation about choice, an anguish of the will divided between good and evil, between appetite and a categorical imperative, between the disposition to virtue or the penchant for vice.


The components of wines in the Tohoku district were investigated.1. White wines1) They showed the high contents of alcohol and non-volatile components and low buffer capacity compared with the foreign wines.2) The strongest correlation was obserbed between the contents of K and the total sulfer dioxide, the light absorbance and the contents of Cu, and the light absorbance and the total sulfer dioxide, respectively.2. Rose wines1) The strongest correlation was observed between the contents of total sulfer dioxide and the contents of alcohol, and the original extract and the light absorbance (420 nm, 460 nm), respectively.2) The rose wines were classified into 3 types by the pattern of continuous light absorption spectrum (370-700 nm).3. Red wines1) The ratio of Ca/Mg of foreign wines showed below 1.0 but the wines of the Tohoku district showed over 1.0.2) All of the mineral components expect K have posittive correlation with pH, buffer capacity and the light absorbance.3) The red wines were classified 3 types by the pattern of continuous light absorption spectrum (370-700 nm).


AbstractInterannual variation in precipitation totals is a critical factor governing the year-to-year availability of water resources, yet the connection between interannual precipitation variability and underlying event- and season-scale precipitation variability remains unclear. In this study, tropical and midlatitude precipitation characteristics derived from extensive station records and high-frequency satellite observations were analyzed to attribute the fraction of interannual variability arising as a result of individual variability in precipitation event intensity, frequency, and seasonality, as well as the cross-correlation between these factors at the global scale. This analysis demonstrates that variability in the length of the wet season is the most important factor globally, causing 52% of the total interannual variability, while variation in the intensity of individual rainfall events contributes 31% and variability in interstorm wait times contributes only 17%. Spatial patterns in the contr...


Abstract This article presents the results of a study of artistry in the practice of research in the social sciences. Traditionally, science and art have been regarded as complementary, one dealing with the expression of feeling, the other with the pursuit of truth. Art, it is widely believed, is largely ornamental in life—nice but not necessary; science is critical to the future. Yet science has a personal side as well as a public one. What is the personal side of science like for those engaged in research in the social sciences? Do artistic considerations function in doing science? If so, where and when? We interviewed social scientists who were fellows at the Center for Advanced Study in the Behavioral Sciences to secure insight into the role that artistry might play in the course of their work. This article describes what we learned.


On October 22, 2010, the outgoing director of the New York office of the U.N. Relief and Works Agency for Palestine Refugees (UNRWA), Andrew Whitley, stunned his listeners at a Washington conference by arguing that "the right of return is unlikely to be exercised to the territory of Israel to any significant or meaningful extent,"? and that UNRWA should help resettle the refugees rather than perpetuate their refugee status. 1 Confronted with a barrage of criticism from the Palestinian Authority and many Arab states, Whitley quickly backed down, claiming, "It is definitely not my belief that the refugees should give up on their basic rights, including the right of return." Middle East analyst Daniel Pipes commented: "That UNRWA might contemplate going out of business and helping end the Arab-Israeli conflict ... was too good to be true."2 Indeed it was, especially when taking into account that UNRWA was established more than sixty years ago on December 8, 1949, as a temporary humanitarian organization: "To carry out in collaboration with local governments the direct relief and works programs"? and to "consult with the interested Near Eastern governments concerning measures to be taken by them preparatory to the time when international assistance for relief and works projects is no longer available." 3 With the passage of time, this modest, transient outfit has evolved into a permanent feature of the Middle Eastern sociopolitical landscape with tentacles spreading well beyond its originally mandated relief operations to virtually all walks of Palestinian life from education, to health, to community-based services, to the PalestinianIsraeli conflict. The propensity for senior UNRWA staff to make inappropriate, incendiary, and highly politicized statements"?in stark contrast to the organization's mandate"?has long been documented by the Jerusalem-based Center for Near East Policy Research. 4 The case made by UNRWA staff, that such statements are a necessary element of protecting the Palestinian refugees, can be seen to be without justification: Nowhere is "protection"? in the political sense part of the UNRWA mandate; UNRWA was originally charged with providing direct relief and work programs, and this was later expanded to include education. Moreover, even if political protection had been mandated, it would not warrant misrepresentations of fact, let alone incitement. This document tracks that trend during the course of 2010 with a special emphasis on the agency's statements concerning the Gaza situation with the author's rebuttals in italics. WHITEWASHING HAMAS In a Sky TV News interview from Gaza, John Ging, director of UNRWA Operations in Gaza, said: The announcement [regarding Israeli intentions in Operation Cast Lead] was that this whole war was about demolishing the infrastructure of terrorism. But we look around and see that this was not the case. The infrastructures of the economy and education were destroyed. And the infrastructure of the governmentministries and the president's compound. These are not the infrastructures of terror, these are the infrastructures of peace-the infrastructures of a state "* the parliament building, the infrastructure of democracy.5 This protestation of innocence is highly disingenuous for it is inconceivable that Ging was unaware of Hamas's propensity for operating from within civilian infrastructure, housing terrorists and weapons in private homes and public buildings (mosques, hospitals, schools, etc.), and using such sites for rocket and missile attacks. 6 By alluding to the parliament building-used by the Hamas terror group, the governing entity of Gaza-as an "infrastructure of democracy,"? Ging willfully distorted the oppressive reality in the strip. In early April 2010-ignoring the years of radicalization of the Gaza population under the influence of Hamas-controlled UNRWA schools 7 -Ging laid the blame for the dismal state of Gaza youngsters at Israel's feet: If you have no reason to live, you will seek a glorious death. …


Cable domes has been widely adopted around the world. A new tensile steel strip cable dome is proposed and a force-finding method of approaching initial shape is introduced. It is easy to be constructed by tow-lifting method without many scaffolds and connect rigid materials directly. The force-finding method of approaching initial shape is effective for the proposed structure.
