word comparison of the first group of 10 manuscripts with the standard text for the whole book, and, besides, for the important places, the variations of the other (13) manuscripts (cf. pp. 8-9, 21-23). The elaborate commentary (pp. 59-88) brings further valuable material for the appreciation of the text. In these notes, quite in harmony with the complicated origin of the Ethiopic text (cf. pp. 23-26), the editor regularly compares the Ethiopic with the LXX-probably a version made by Aquila (cf. p. 1)and the Hebrew. But very frequently he uses also the testimony of the Vulgate, the Syriac, and the Arabic, which have influenced the Ethiopic at different times, and occasionally the Coptic and the Targum, whose traces may be discerned in several places, are called on for their evidence. This textual commentary will be highly appreciated by the student, who will find here an abundance of excellent material presented in a clear manner. As is to be expected, a minor point may have been overlooked occasionally. Thus the reading of AA (under the sun) in 3:1 given as found only in the Syriac appears in the Aldine edition according to the variant registered in Vigouroux's Polyglot. The reading of 1:13a (all that has been done), about which there is nothing in the commentary, agrees with the Sinaiticus and other Greek authorities rather than with the Vaticanus (all things that are done). The explanation of 2:2b (p. 61) would seem to imply a misprint in the Ethiopic. It is unfortunate that the Arabic words or phrases should have fared so badly at the hands of the printer; except in the notes on 2:3; 5:19; 8:17, the Arabic is more or less disfigured everywhere else (cf. notes on 1:2; 1 :16; 2:10; 6:8; 7:13; 7:30; 8:4). But such details in no wise affect the great value and usefulness of the work. We congratulate Dr. Mercer on this fine edition and hope that he will give us some other fruits of his successful expedition to Abyssinia (p. ix), some other parts of the Ethiopic Bible in similar critical editions.


The concept of green technique in coal mining was proposed. Its connotation and technical system were explained. The theory foundation of the green technique in coal mining is the distribution behaviour of joints, fractures and bed separations, the seepage flow behaviour of methane and water in the broken rock strata caused by the key strata break after mining. The main content of the green technique in coal mining includes water-preserved-mining, coal mining under building and bed separation grouting to reduce surface subsidence, partial extraction and backfill mining, simultaneous extraction of coal and coal-bed methane. coal roadway supporting, underground discharge of partial rock refuse and underground coal gasification, etc.


Abstract The current Covid-19 pandemic has impacted tourism industry the hardest and has steered a total standstill in the multibillion industry, causing economic crisis globally. This paper attempts to assess the impacts and management strategies of agritourism in Brunei. Due to the constant evolvement of knowledge and management strategies during this unprecedented time, qualitative approach using semi-structured interviews was deemed appropriate for this research. This paper focuses on agritourism farms in Brunei during Covid-19 to study the implication and contingency plans to divert such crises. Findings from this study indicates that strategies employed by the Brunei agritourism farms were (1) the diversification of economic activities towards product innovation and agribusiness expansion to mitigate tourism revenue loss; (2) digital transformation such as, contact tracing app, the introduction of virtual tourism as well as the use of social media to promote agritourism as lower-risk tourism; (3) adaptive human resources strategy by encouraging community capacity building such as upskilling and training of local farmers to stimulate new agritourism skills and establish more future-ready workforce. The strategies adopted by the agritourism farms in Brunei could provide lessons to neighbouring countries and the ASEAN region to prepare for a crisis-resistant agritourism in the future.


Several economic feasibility studies of solar heating in the Northwest are described. The case for federal assistance to the solar industry and the consumer is developed. The solar-related activities undertaken by the Northwest states of Oregon, Idaho, Washington, and Montana are detailed. Finally, roles are addressed which municipal government may play either to encourage or to deter the widespread use of solar heating systems. (MHR)


This paper deals with the concept of "residential models" and the role it plays on human relations in residential complexes. It intends to; review the concept of residence; understand how a residential model takes form; the influence of a residential model on future human interactions. To this end, having reviewed comments and viewpoints, focused on "what is residence? which factors may create the sense of residence and how an individual can choose his/her place of residence? Finally what are the factors affecting their choice". Then two residential models analyzed: balanced and unbalanced, and their effects on human relations. Afterwards the research hypothesis was posed: "residential model is an effective factor on human relations". Whereas the above study is limited to a small number of complexes in Tehran, for the purpose of testing the hypothesis and, in turn, for determining sample population, the residential complexes were classified into three categories in terms of facilities, features and characteristics. From each category a sample was chosen for testing the hypothesis. It was eventually decided to test the hypothesis in Ekbatan, Behjatabad and Farhangian residential complexes. The results indicated a strong relationship between residential model and its impact on human relations: more balanced the residential model, stronger effects on human relations. On the other hand, more unbalanced the residential model, weaker effect on human relations.


Ministers debated for etiquette in defending the petition of the ceremony,which earliest happened beside the Wen Hua door in Ming Dynasty in Cheng Hua period.This etiquette releted Empress Zhou(the Mother of Xian Zong).There were different views about obsequies between Empress Zhou and ministers.Her selfish and dour determination provoked ministers petition.In consequence,the obsequies not only provoked great change of imperial family,but also became the beginning of petition campaigns about admonitory advisement to rulers who would disobey the rituals during his reign.


Motivated by the need of resource flexibility in high throughput satellite systems, a hot-spot cell configuration is introduced and analyzed in terms of throughput performance. Cell partitioning and user scheduling are also addressed in conjunction with the application of different types of linear precoding algorithms. The analysis is based on a real satellite system design and uses a system simulation approach, encompassing the random user distribution inside the hot-spot cell area. Results provide guidelines on the design of the hot-spot cell partitioning and show the achievable gains of precoding with respect to conventional, non precoded, transmission.

With the bad turn of the word- wide environment, the concept of the sustain- able development has gone deep into the people's heart and "green" concept has filtered into every trade. At present, the requirement of the people to the housing interior design is raised day by day. It is the common wisn orthe people who living today and in the futrue to combine "green" concept with the housing interior design, to create the comfortable "green" interior space.


In this work, an alternative approach to synthesize (K,Na)NbO3 (KNN) particles is investigated. KNN hydrate particles were prepared by hydrothermal method in a mixed alkaline solution with different KOH/(KOH+NaOH) ratios , and phase structure as well as surface morphology of these niobate hydrate particles were systematically studied. For the reaction rate of Na+ is faster than K+, a mixed alkaline solution with K+/Na+ changing from 4/1 to 5/1was required as a starting solution so a to obtain KNN hydrate particles with K/Na=1. Besides, the results show that particle size of KNN hydrate particles synthesized in different starting solution is dependent on K+/Na+ of the starting solution, and grain size of as-sintered KNN ceramics through hydrothermal method decreases sharply.


Human exposure to microplastics through inhalation has been widely reported in recent years. There is a paucity of work focusing on the direct effect of accumulation of microplastics in airways and how it may impact the respiratory function. This study aimed to investigate whether the exposure of microplastic would change the contractility of isolated airway smooth muscle tissue. Microplastics were obtained through milling of high-density polyethylene (HDPE) pellets by using a centrifugal mill. To confirm that the milled microplastic particle size range fell within the definition of microplastic, field-emission scanning electron microscope (FESEM) was employed. The milled microplastics particle size ranged from 44.2 µm to 552.4 µm. The organ bath technique was employed to study the direct change of tissue contractility of rat isolated tracheal rings. Tracheal rings were incubated with polyethylene microplastics of different concentrations (0.3 mg/ml to 10 mg/ml) for a minimum of 18 hours in physiological Krebs buffer, followed by the construction of concentration-response curves to a contractile agent, carbachol (muscarinic agonist). Exposure to all concentrations of polyethylene microplastics enhanced the contractile responses of the tissues to carbachol. However, the effect was only statistically significant in tissues incubated at 3 mg/ml and above (p < 0.05). Findings from this study provide preliminary evidence that exposure to polyethylene microplastics adversely affects airway function. Heightened contractile responses of airways mimic the pathophysiological responses in respiratory diseases such as asthma, chronic cough and chronic obstructive pulmonary disease. Further experiments focusing on the possible mechanism of actions of these microplastics affecting the airway tissue function are now needed.


Introduction: Boredom is a negative psychological and emotional experience prevalent in foreign language classrooms. However, it has long been neglected by researchers and foreign language teachers. In this context, the present study investigated boredom experienced by college English majors in a blended English reading course. Research efforts revolved around students' overall boredom level, gender differences, and dynamic changes in boredom. Methodology: This study adopted a quantitative research method, and the instrument was a quantitative questionnaire adapted from the Foreign Language Learning Boredom Scale. A total of 174 EFL learners (60 males and 114 females) in the second year of English majors from a private university in Southwest China filled out the online version of FLLBS in weeks 3, 9, and 15 during the fall semester of 2022-2023 academic year. Results: The findings demonstrated that participants' boredom was at a moderate level. Moreover, except in foreign language class boredom at Time 2 and over-challenging or meaningless task boredom at Time 3, there existed no significant gender differences. Finally, a complicated picture was painted regarding the dynamic changes in boredom levels over time, and different patterns were found. Conclusion: College EFL learners do feel bored in the learning process, which should not be neglected by language teachers and researchers. This study enriched the research on foreign language boredom and can provide enlightenment to EFL teaching.


A B S T R A C T Trans-fatty acids (TFA) are known as a risk factor for coronary artery diseases. Trans-11 vaccenic acid [VA; 18:1(n-9)], known as the major trans fatty acid in milk fat, is a positional and geometric isomer of oleic acid and a precursor of conjugated linoleic acid (CLA) in human . This study was carried out in order to investigate the effect of Cis and Trans Vaccenic Acids on expression of intra cellular adhesion molecul-1 (ICAM1) and vascular cellular adhesion molecul-1 (VCAM-1) in human Microvascular endothelial cells (HMECs). To induce adhesion molecules expression, TNF-α or LPS were added to HMECs in a cell culture being treated with Cis and Trans vaccenic acid. In the next step, to evaluate ICAM-1 and VCAM-1 expression before and after the treatment, Western blot technique was used. The analyzed results indicated that Cis and Trans vaccenic acids are able to suppress VCAM-1 and ICAM-1 expression on HMEC near to the basal level. Also it has been found that cis vaccenic acid isomer could suppress both VCAM-1 and ICAM-1 expression as well as trans isomer. Together all and considering the role of mentioned adhesion molecules in atherosclerosis; it seems that Cis and trans vaccenic acids could be a possible prophylaxis agents in populations with high risk of atherosclerosis.


This report presents the results of a study to investigate the role and future
development of supportive housing for older people in Ireland. For purposes of the
study, supportive housing was defined as group or sheltered housing schemes for older
people where the residents have their own apartments or houses. The key feature is
having one's own home but within a purpose-built, clustered arrangement rather than
individual homes dispersed throughout the community. Within this definition there is a
continuum in the amount of support and care that is provided for residents.
This focus on supportive housing as defined above is timely in view of the increasing
policy attention being given to this area in Ireland, in particular to sheltered housing.
High expectations are being placed on it in relation to meeting housing and care needs
of older people and delivering on the policy objective of avoiding, or at least delaying,
the necessity for older people to move to residential care because they can no longer
live independently in their own homes.


A new polishing tool named magnetic compound fluid(MCF) wheel is proposed and the experimental apparatus is developed in order to polish optical glass efficiently and precisely.The theoretical analysis of the magnetic field distribution in the circumference surface of the MCF wheel is carried out using scalar magnetic potential method and vector superposition theorem.The analytical expression is verified by the actual magnetic field distribution measured with digital teslameter.According to Preston equation,the relation of the material removal with the magnetization pressure is discussed.The polishing characteristics of fused silica glass are experimentally investigated the effect of magnetic field distribution on material removal.The maximum depth are 13 m and 8 m after polishing for 120 min with the magnetic pole arrangement of NS-SN distribution and NS-NS distribution respectively,and little work materials are removed at the central areas with NS-NS pole distribution.It can be concluded that the higher material removal can be obtained by the MCF wheel with the magnetic pole arrangement of NS-SN distribution.


TiO2/CeO2 nanocomposites of anatase TiO2 nanoparticles supported on microsized mesoporous CeO2 were prepared and characterized by SEM, TEM, BET, XRD, Raman, XPS, and diffuse reflectance UV–vis absorption. The formation of the TiO2/CeO2 nanocomposites considerably enhances their catalytic activity for the gas-phase oxidation of benzene, one of the hazardous volatile organic compounds (VOCs), under the irradiation of a Xe lamp compared to pure CeO2 and TiO2. A solar-light-driven thermocatalysis on CeO2 is found for the TiO2/CeO2 nanocomposites. There is a synergetic effect between the photocatalysis on TiO2 and the thermocatalysis on CeO2 for the TiO2/CeO2 nanocomposites, which significantly increases their catalytic activity. The CO2 formation rate (rCO2) of the TiO2/CeO2 nanocomposite with the Ti/Ce molar ratio of 0.108 under the synergetic photothermocatalytic condition is 36.4 times higher than its rCO2 under the conventional photocatalytic condition at near room temperature. CO temperature-programmed r...

The theoretical base of the "Three Ropresentatives" lies in dialectical materialism and historical materialism. The philosophical base for the development of China's advanced pro- ductivity, represented all the time by the CPC, is historical materialistic principle, that is, pro- ductiveness is the final decisive factor for social development. The philosophical base for the devel- opment of China's advanced culture, represented constantly by the CPC, is historical materialistic principle, that is, the social existence determines the relationship of social consciousness. And the philosophical base for the essential interest of the great majority of the people,represented now and then by the CPC, is historical materialistic principle, that is, people are the creators histo- ry. The interrelationship among the "Three Representatives" is of dialectic unity.


Abstract In a numerical model of the equatorial Pacific Ocean, the ∼20-day period tropical instability waves, excited in the eastern half of the domain, are found to damp the strong zonal mean currents. The waves generate large, nonlinear, advection terms in the momentum balance, change the vorticity balance, and thus modulate the low-frequency state. The authors explore whether the effect of tropical instability waves on the background flow can instead be adequately parameterized by a constant-coefficient Laplacian friction scheme. On annual mean, a Laplacian friction coefficient that varies in space is required, for the coefficient is twice as large along the equator and a few degrees more to the north than elsewhere. In addition, wave activity varies in time. During active phases, such as the second half of the year and during La Ninas, the activity increases, which would require the Laplacian coefficient of friction to be at least twice as strong as during the inactive phases. Thus, a more sophisticat...


Purpose: Uncertain position of the acetabular implant has been the cause of dysfunction in certain cases of total hip arthroplasty (THA). Classical computed tomographic analysis of anteversion has certain limitations. Integrated reconstruction of positions at risk allows a better diagnostic approach. Material and methods: We studied 46 THA because of posterior malposition (n=17, anterior subluxation in the standing position in twelve, and true dislocation in five) and anterior malposition (n=29, posterior subluxation in sixteen and true dislocation in thirteen). Two groups of 70 naive hips and a group of 56 THA with no functional problem served as controls. The position of the acetabulum was studied on optimised computed tomography slices reconstructing the planes of analysis for the standing, sitting and reclining positions. The reference planes for the slices was given by the sacral tilt angle measured on the lateral views of the patient in the corresponding positions. The optimised computed tomographic measurements of anteversion were compared with the classical measures. None of the patients had abnormal femoral anteversion and/or an oblique pelvis and/or leg length discrepancy greater than 10 mm. The frontal inclination of the acetabular implants was 40°–50°. Results: In the naive hips, acetabular anteversion varied: 19.2 with the conventional method, 15.7 in the standing position and 31 in the sitting position. In the THA controls, anteversion measurements differed: 21.3 with the conventional method, 21.4 in the standing position and 35.8 in the sitting position. In the THA with a posterior malposition, 18/29 could not be explained by the conventional measurement, but the optimised measurement enabled an understanding in 17 hips (defective anteversion in the sitting position). Discussion: Changes in pelvis orientation between the sitting and standing positions modifies real anteversion of the cup. In particular, subjects with THA tend to have a spontaneous posterior tilt of the pelvis related to trunk ageing. This element should be taken into account for the analysis of both major and minor THA dysfunction.


Prior research has typically explained the positive intrapsychic influence of political skill using Conservation of Resources (COR) theory. However, theoretical and empirical research explaining possible negative intrapsychic consequences of maintaining a high level of political skill is lacking in the literature. Therefore, we introduce Cognitive Activation Theory (CAT) to the political skill literature to theoretically explain possible negative outcomes of political skill. In order to test this theory, we examined the relationship between affective and continuance commitment, life satisfaction, and political skill in a large Latin American organization. Consistent with both COR and CAT, results indicated that political skill strengthened the relationship between affective commitment and life satisfaction. However, contrary to COR, but in line with CAT, political skill weakened the relationship between continuance commitment and life satisfaction.


Objective:To compare the efficacy and security of various doses of citalopram to the depressive patients. Method:Patients with depressive episode were orally administered citalopram 20 mg/d or 40 mg/d respectively for six weeks.Hamilton depression rating scale(HAMD),clinical general impressional scale(CGI)and treatment emergent symptom scale(TESS) were assessed. Results:31 patients were observed for 6 weeks,14 patients were treated by 20 mg/d and 17 patients were treated by 40 mg/d.The efficacy rate and the recovery rate of the 20 mg/d group and 40 mg/d had no remarkabled difference,retarded factor of HAMD was significantly better in 20 mg/d group than 40 mg/d group.Anxiety factor was significantly better in 40 mg/d group than 20 mg/d group.There was no significant difference between the adverse reaction rate of two groups. Conclusion:Citalopram shows excellent therapeutic effect for depressive patients both in 20 mg/d and in 40 mg/d and also has little adverse effect which is easy to be tolreant.


The effects of several antioxidants added to cryopreservation extenders on turbot (Scophthalmus maximus) sperm post-thaw motility, fertilization, sperm characteristics, and DNA damage were investigated. The following antioxidants were used in conjunction with the conventional extenders: rosmarinic acid (RA) (25, 50, and 100 μg/ml); uric acid (UA) (25, 50, and 100 μg/ml); and taurine (TA) (25, 50, and 100 μg/ml). On sperm samples that had been diluted by the extenders at a 1:9 ratio, cryopreservation was carried out. The results demonstrated that the post-thaw motility of sperm was higher in 25 μg/ml RA (77.41±2.90%), followed by 50 μg/ml RA (74.86±3.2%), 50 and 100 μg/ml UA (69.56±3.30% and 70.74±2.51%, respectively) which significantly differentiated from conventional extender. The highest hatching rate (70.67±4.67%) was attained at UA 50 μg/ml, while the highest fertilization rate (81.67±2.52%) was observed in RA 25 μg/ml. At UA 50 μg/ml, the DNA fragmentation rate was lowest (5.07±1.57%). In conclusion, antioxidants had a protective impact on sperm of turbot that had been frozen and thawed.


Western Kenya and Southeast Uganda have reported different Human African Trypanosomiasis (HAT) incidences in the past more than 3 decades with the latter recording more cases. Here, we describe interactions between socio-economics, tsetse dynamics, livestock husbandry and environmental issues at the transboundary of Kenya and Uganda and how they determine Human African Trypanosomiasis (HAT). Comparative studies were carried out in two districts of each country namely Teso and Busia Districts, of Western Kenya and Tororo and Busia Districts, of Southeast Uganda. In addition, primary data was collected in the selected villages for the livestock numbers and human population. Also structured questionnaire was administered systematically to 384 randomly selected household heads or their representatives in each country. Human population density and types of crops grown, livestock numbers and livestock husbandry in the study villages influenced the occurrence of HAT. Prophylactic administration of tyrpanocides and topical application of insecticides on livestock reduced incidence of HAT. Wildlife abundance was high in villages reporting a history of HAT (69%) than HAT free villages (35.5%). The Glossina pallidipes trapped in the study areas sourced their blood meal exclusively from cattle. Therefore livestock keeping practices, wildlife and environmental factors should be incorporated into tsetse and trypanosomiasis control.


Originally published in Contemporary Psychology: APA Review of Books, 1990, Vol 35(4), 338-340. Reviews the book, Nonlinear Psychophysical Dynamics by Robert A. M. Gregson (see record 1988-98761-000). This book proposes a "simple" model for psychophysical dynamics, motivated by 19 "properties" of psychophysical data that should be accounted for merely by changing values of model parameters or environment/model couplings. I doubt deeply that anyone will read this book. Actually, it cannot be read; it must be studied, and that really only after studying the earlier book as well as system theory and the mathematical theory of chaos. How many psychophysicists will do this? I do not think very many will, given the history of the discipline. This is too bad, for there are many provocative ideas in this book. However, I believe that a different kind of book is needed to bring chaos into psychophysics and into psychology, one that is more approachable by the average psychophysicist.

Multistability in perceptual tasks has suggested that the mechanisms underlying our percepts might be modeled as nonlinear, deterministic systems that exhibit chaotic behavior. We present evidence supporting this view, obtaining an estimate of 3.5 for the dimensionality of such a system. A surprising result is that this estimate applies for a rather diverse range of perceptual tasks. The current state of the chaos construct and supporting empirical research in psychological theory is summarized in neuroscience, psychophysics, psychomotor skill and other learning phenomena, clinical and abnormal psychology, and group dynamics and organizational behavior. Trends indicate that human systems do not remain chaotic indefinitely; they eventually self-organize, and the concept of the complex adaptive system has become prominent.

Background: Amphetamine-type stimulant (ATS) often damages cardiomyocytes through its sympathomimetic properties. Here, we present an autopsy case report describing ATSassociated cardiomyopathy (ATSAC) in an individual with a history of methamphetamine abuse of over 30 years. Case report: A 50-year-old man was found deceased at his home. Just 3 days before his death, he had been released from prison after serving a 3-year sentence, during which period he had stopped drug use. Although the hearts of patients with ATSAC are generally hypertrophic or dilated, his heart showed a normal appearance. Histologically, heart failure cells were evident in the lungs. The myocardium consisted of a mixture of hypertrophic and atrophic cardiomyocytes. Contraction band necrosis and lipofuscin accumulation were evident. Immunostaining for tenascin C was negative. These findings indicated extensive damage to the cardiomyocytes. We diagnosed the cause of his death as pulmonary edema due to chronic heart failure, despite the normal appearance of the heart. ATSAC is generally reversible after cessation of drug use. However, in this case, extreme long-standing abuse of methamphetamines resulted in severe damage to cardiomyocytes and consequent loss of recovery capacity. Conclusion: To the best of our knowledge, this is the first case report describing atrophic cardiomyocytes in a long-standing ATS abuser. The present findings highlight the importance of histopathological examination in such cases, regardless of external tissue appearance.


In the present paper, we first prove a new integral identity. Using that identity, we establish some fractional weighted midpoint-type inequalities for functions whose first derivatives are extended s-convex. Some special cases are discussed. Finally, to prove the effectiveness of our main results, we provide some applications to numerical integration as well as special means.


The function of biosurfactant which was produced by Pseudomonas aeruginosa S6 in biodegradation process of anthracene was studied.The results showed that the biodegradation was enhanced by biosurfactant of 60mg·l-1 when it was added 1 day before and at the same time with inoculum of degrading strain A10,and the degradation rate increased by 16.50% and 18.03% compared with control,respectively.Excessive biosurfactant could inhibit biodegradation of anthracene to some extent.The analysis of degradation process of anthracene exhibited that addition of biosurfactant ahead of degrading strain could promote anthracene degradation evidently and keep preferable effect.Biosurfactant could be utilized by strain,suggesting its bioavailability,thus it is an environmentally friendly biological reagent.


In this study, thermoelectric based energy harvesting system which utilizes the temperature gradient between the hot lubricant oil inside the azimuth thrusters and cold sea water outside the azimuth thrusters is proposed. Coupled modeling of the fluid dynamics for the oil flow inside the thruster and heat transfer between the hot oil, thermoelectric generator (TEG) module, other solid components in the system and sea water is built. The temperature distribution in the system is simulated and temperature gradient between the hot surface and cold surface of the TEG is extracted and analyzed. The system is further optimized to achieve the higher temperature gradient between hot and cold surface of the TEG by utilizing bigger size of the enclosure for the TEG, adding a heat sink at the hot surface of the TEG, choosing the lubricant oil with higher thermal conductivity and driving higher velocity of the oil movement. Lastly, the effect of the bio fouler layer on the temperature gradient of the TEG module is evaluated.


A facile single-stage process for enhancing the antibacterial activity and UV-shielding property of cotton and viscose pigment prints was reported. Results indicated that both the functional and coloration properties of the obtained pigment prints were improved significantly by incorporation of TiO2 nano sol (average molecular size ≈5 nm, 15 g/kg) into the solvent-free pigment printing pastes. Differences in the imparted antibacterial activity and UV-blocking properties as well as in the depth of the modified pigment prints were attributed to the differences in the type of cellulosic substrate, efficiency of the used binding agent, extent of loading, and immobilizing both the TiO2-NPs and pigment particles during the microwave-fixation step as well as on the type of pigment colorant. Also, the obtained results demonstrated that the modified pigment prints, i.e. TiO2-NPs-loaded pigment prints, showed durable antibacterial efficacy and UV-shielding capacity even after 15 washing cycles, regardless of the used substrate. The scanning electron microscope images and EDX spectra of selected samples were also reported.


The LED lighting market is growing annually, however high prices remain a barrier, especially in the incandescent replacement market [1]. Many LED bulbs, such as the A19 (the "classic" light bulb shape), MR16 (Multifaceted Reflector, 16 eights of an inch in diameter), and PAR30 (Parabolic Aluminized Reflector lamp, 30 eights of an inch in diameter) could benefit from the use of plastic materials to reduce assembly costs and weight, as well open up design freedom and part consolidation. However, current plastic solutions in the market can be expensive and have low thermal conductivities. This paper details the use of a novel polycarbonate resin with a high thermal conductivity up to 40 W/m-K. The use of polycarbonate reduces moisture uptake and enhances molding conditions, while bringing the cost efficiencies of metal to plastic conversions. In thermal simulations and actual heat sink fabrications, this novel polycarbonate offers similar or better LED case temperatures than cast aluminum. In terms of durability, temperature cycling and thermal shock cycling shows no signs of cracking or deterioration. This has helped the resin obtain a UL f1 rating for outdoor exposure and water immersion, and it should be noted that the plastic will not corrode like aluminum. The polycarbonate resin can also be powder coated with excellent adhesion. Finally, because polycarbonate is a plastic, designers can mold various features into the plastic that can reduce assembly costs and increase efficiency.


A same-scale comparison of conventional railguns, augmented railguns, and helical launchers is presented and discussed. While the ideal launcher is always 100% efficient, practical launchers have an efficiency which is a function of the projectile velocity and a new parameter called the characteristic velocity. The characteristic velocity is the velocity needed for 50% maximum efficiency. The motivation for a same-scale comparison is an accounting for the velocity-dependent efficiency effect. The same scale concept states that launcher comparisons should be done on an equal bore diameter, launcher length, projectile mass, and velocity basis. Other parameters developed by the authors and included in the analysis, are the launcher constant and the mode constant that account for the launcher geometry and the mode of operation, respectively. The analysis uses experimental data collected by the authors with conventional railgun, augmented railgun, and helical gun launchers


3D needle insertion is important both in theoretical research and clinic practice. In literature, most needle insertion experiments use 2D experiment platforms. A few studies use 3D experiment platforms based on ultrasound or traditional stereo camera. The ultrasound has low resolution and traditional stereo camera is difficult to reconstruct objects without textures, which is not suitable for markers reconstruction. Hence, it is needed to design a 3D needle insertion experiment platform with high resolution and 3D reconstruction ability. In this paper, we design a 3D needle insertion platform based on the orthogonal-arranged dual camera. Error analysis and accuracy verification are carried out as well. First, experiment platform framework is designed and essential modules are introduced. Second, the error analyses based on Frechet distance are carried out to quantify the error led by the bevel facing angle and insertion angle. Third, to verify the 3D reconstruction accuracy, the 2D distance sensitivity experiments and 3D reconstruction experiments are carried out for the dual camera system. The accuracy of 3D reconstruction in the region of interest has been verified. To optimize the 3D needle insertion platform, a needle holder to ensure concentricity is applied. Besides, pre-insertion process and orthogonal-arranged double chessboard calibration are introduced into setup procedures. Finally, a 3D needle insertion experiment platform is designed and validated through needle path planning algorithm verification. Results show that the proposed experiment platform can steer the needle accurately and reconstruct the needle path and markers in acceptable accuracy.


IN RECENT years, an "Africa rising" narrative has foretold a continent of growing economic and strategic importance—a continent coming into its own. While no single narrative can fully encapsulate a dynamic and diverse region of 49 countries and one billion people (in sub-Saharan Africa), there is truth to the storyline that Africa is becoming increasingly important in the global economic order, and that it will further grow in strength and influence over time. This is partly because Africa has for too long been marginalized and insufficiently integrated into the global economy, and partly because of the region's great potential.


The arrival on the breeding grounds and habitat use in relation to agricultural land use by Lapwings Vanellus vanellus was compared in rough grazing and arable study areas in the Midland Valley of Scotland. First arrivals took place in early February. Males preceded females and territory occupation by the males began soon after first arrival. During the pre-breeding period birds remained in flocks and day time habitat use and activity was strongly influenced by the lunar cycle. Birds fed mainly in those habitats in which prey (leatherjackets and earthworms) were most plentiful, and in which their feeding success was high. The choice of nesting habitat was not influenced by food availability in the immediate vicinity of the nest site but by the crypticity of the clutch and incubating adults. On rough grazing birds preferred unimproved land while on arable land spring cereal was the preferred habitat. The choice of actual nesting field on the arable land was influenced by the risk of predation and the proximity of suitable feeding fields for the adults and chicks.

The contribution of epidemiology to quality assessment and monitoring: a clear enough subject. But as I approached it, it slipped into ambiguity and confusion. What was quality assessment? What was monitoring? For that matter, what was quality? And the meaning of epidemiology was the deepest mystery of all. I must begin by defining my terms. Quality shall be taken to mean making a judgment on the goodness of healthcare, based on one or more of the following: the expected or realized ability of the care to achieve the greatest improvement in health that the current science and technology of healthcare can achieve; acceptability to patients (including their families); and acceptability to the community (or the society at large). There are three ways in which we can find out if healthcare has been good in these respects. First is the examination of the process of care, which I take to mean the degree to which what is done for and by patients corresponds to what is known or believed to be most effective in improving health, and most acceptable to patients and to society. Second is the examination of the outcomes of care, meaning the degree to which the care provided is acceptable and has attained achievable improvements in health. Third is the examination of structural attributes, meaning the degree to which the physical and organizational settings in which care is given are conducive to the kind of care that can be expected to improve health and to be acceptable to patients and to the community. So much for quality assessment.


In your October '85 edition you published an excellent paper entitled, The Evolution of Configuration Management, by Rudy Bazelmans.Unfortunately the article did not cover any material describing UK developments, so I have taken the liberty of providing some information on the development of our automated Configuration Management system called LIFESPAN.


The world's population is rapidly aging, which affects healthcare budgets, resources, pensions and social security systems. Although most older adults prefer to live independently in their own home as long as possible, smart living solutions to support elderly people at home did not reach mass adoption, yet. To support people age-in-place a Living Lab is established in one of the metropolitan areas in the Netherlands. The main goal of the Living Lab is to develop an online health and wellbeing platform that matches service providers, caretakers and users and to implement that platform in one particular city district. In this paper we describe the narrative of the action design research process that will give researchers insight how to deal with complex multistakeholder design projects as well as cooperation issues to develop an artifact in a real-life setting.


[reaction: see text] Stannylaminyl radicals derived from radical reactions of Bu(3)SnH with azidoalkylmalononitriles exhibit highly efficient 5- and 6-exo cyclization onto either nitrile group to give aminoiminyl radicals that in turn are reduced to amidines or undergo successive 5-exo cyclization onto an internal alkene.


Abstract BACKGROUND: Oily skin, characterized by excessive sebum production, can lead to acne and have psychosocial impacts due to changes in appearance. Recent research has shown interest in treatments for oil control, with kaolin and bentonite emerging as promising options. Despite their potential, comprehensive studies on these ingredients are still in the nascent stages. AIM This study aimed to assess the efficacy of a clay mask (La Roche‐Posay Effaclar Sebo‐Controlling Mask) in reducing skin oiliness and acne, and its safety for use. METHODS In this study, 75 adults with oily or combination skin were enrolled and provided with a clay mask for twice‐weekly use over 4 weeks. Clinical assessments, using instruments like Sebumeter, Vapometer, and Corneometer, were conducted at baseline, and after 1, 2, and 4 weeks, evaluating acne lesions, skin irritation, sebum content, and skin hydration. Participant self‐assessment questionnaires were also utilized for subjective evaluation. Statistical analyses were performed accordingly. RESULTS The study revealed significant improvements in acne‐related outcomes, sebum content, skin evenness, stratum corneum water content, and transepidermal water loss following the application of the clay mask. Pore area and porphyrin area showed no significant changes. Tolerance assessment showed reduced dryness and irritation, with self‐assessment indicating high product acceptability and perceived oil control effectiveness. CONCLUSION This study demonstrated the clay mask's efficacy in managing acne and oily skin, improving hydration and texture. Significant improvements in skin parameters and high product safety were observed, supporting its suitability.


The problem of turbulent spectrum engenders two coupled hierarchies: one originates from the development of stress, leading to a transfer function, and the other from the development of an eddy viscosity. In order to incorporate physical roles among scales, the turbulent velocity fluctuation is decomposed into a series of ranks in the increasing order of randomness, contributing successively to energy or stress, eddy viscosity, relaxation frequency, and higher‐rank frequencies in the memory chain. As a result, the first hierarchy mentioned above becomes closed at the quadrupole correlation. The second hierarchy governs the eddy viscosities of different ranks, related to relaxation frequencies of such ranks, in the form of a memory chain. It is cut off by an implicit viscous mechanism. For zero wind gradient, the spectrum in the inertial subrange recovers the Kolmogoroff k−5/3 law with a numerical constant 1.58, in good agreement with experiments. For a strong wind gradient, the spectrum in the production ...


This paper presents a series solution to the image charge fields of a single ion in a Penning trap. The calculation of these fields and resulting frequency shifts will be important for advances in a variety of high precision Penning trap studies, particularly for work with highly charged ions. The simple technique is applicable to cylindrically symmetric traps of otherwise arbitrary geometry and provides an efficient alternative to finite grid relaxation techniques. The present calculation is in agreement with previous measurements in a hyperbolic trap, and systematic frequency shifts for recent atomic mass measurements using multiply charged ions are given.


In article questions of influence of factors of professional work on health of em-ployees of field services of a federal fire service of the Ministry of Emergency Measures of Russia are considered; the technique of an estimation of this influence is offered; the med-preventive actions limiting negative influence of professional factors on health are developed.


A method for generating the frame information of a dynamic image and an apparatus using the same are provided to control the dynamic image constituted by various objects by frame, thereby enabling various arrangements and dynamic effects of components only with small storage requirements. A script parser(210) recognizes plural objects constituting a dynamic image. A reproduction time calculating unit(220) determines a temporal position to be frame during the total reproduction time of the dynamic image. A frame information recording unit(230) records the property of the objects at the temporal position. A script(30) is generated by a dynamic image generator. An execution module(40) shows the dynamic effect of the objected analyzed by the script parser.


Wikinews began in November 2004 as a collaborative online journalism project and sister project of Wikipedia, the well-known collaborative online encyclopedia. This article explores how Wikinews members have defined "news" and the ramifications of that definition for how they have been able to produce news collaboratively. One of the defining characteristics of Wikinews is a dedication to the neutral point of view (NPOV) policy, which was adopted from Wikipedia. NPOV serves as a structuring device for defining news, but also conducts a great deal of organizational work and is in turn structured by the discourses and debates of NPOV in stories. Further, a commitment to an organizational culture of consensus and collaboration, although not without handicaps in a news production environment, is a laudable achievement among Wikinews participants and could be a precursor to the way that citizen journalists will become more involved in news production in a sustainable way.


2-tert-Butyl-1H-1,3-benzazaphosphole (1a) reacts with tBuLi without addition to the P=C bond to form a lithium benzazaphospholide that affords the η1-(benzazaphospholide-P)tungsten(II) complex 2 upon reaction with [CpW(CO)3Cl]. It is sensitive to alcoholysis and to air oxidation yielding 1a and the P-oxo-benzazaphospholide complex 3, respectively. The (1,3-benzazaphosphole)pentacarbonyltungsten complex 4, obtained from 1b and [W(CO)5(THF)], reacts preferentially with tBuLi by lithiation of the NH function and is attacked by [CpW(CO)3Cl] at phosphorus to give the mixed valence bimetallic tungsten(II)-tungsten(0) benzazaphospholide complex 5. A side product, (3-tert-butyl-2-methyl-1,3-benzazaphosphole)pentacarbonyltungsten (6), is attributed to side-reaction where tBuLi adds to the P=C bond in 4. The composition of the products was determined from X-ray structure analysis of 3 and spectroscopic data.


The Manufactured Home Energy Audit (MHEA) is an energy audit tool designed specifically to identify recommended weatherization measures for mobile homes as part of the U.S. Department of Energy's (DOE's) Weatherization Assistance Program. A field validation of MHEA was performed using billing/delivery data collected on 86 mobile homes heated primarily by electricity, natural gas, or propane to assess the audit's accuracy and the validity of its recommendations. The validation found that MHEA overpredicts the annual space-heating energy savings of weatherization measures to be installed in mobile homes, which leads to low realization rates, primarily because of its large overprediction of annual pre-weatherization space-heating energy consumption. However, MHEA's annual space-heating energy savings estimates and realization rates can be improved considerably using MHEA's built-in billing adjustment feature. In order to improve the accuracy of MHEA's annual space-heating energy savings estimates and realization rate, the cause of MHEA's overprediction of annual pre-weatherization space-heating energy consumption needs to be further investigated and corrected. Although MHEA's billing adjustment feature improved MHEA's annual space-heating energy savings estimates, alternative methods of making the correction that may provide improved performance should be investigated. In the interim period before permanent improvements to MHEA can be made, the following recommendationsmore » should be followed: (a) do not enter into MHEA insulation thicknesses of 1 in. or less and especially zero (0 in.) unless such low levels have been verified through visual inspection of several parts of the envelope area in question; (b) use MHEA's billing adjustment feature to develop a list of recommended measures based on adjusted energy savings if possible, especially in mobile homes that have several major energy deficiencies; and (c) do not use MHEA's "evaluate duct sealing" option at this time (although certainly seal all duct leaks and use diagnostics as appropriate to find leakage sites and quantify improvements).« less


Flow cytometry was employed to determine the coelomocytes/hemocytes DNA content in five selected marine invertebrates from the Adriatic sea (sea mouse Aphrodita aculeata, spiny crab Maja crispata, starfish Echinaster sepositus, sea urchin Paracentrotus lividus and tunicate Phallusia mammillata). The cell cycle analyses identified sea mouse coelomocytes as proliferating cells and revealed that spiny crab hemocytes and sea urchin coelomocytes complete their division in the hemolymph and coelom, respectively. The diploid DNA content (2C) in sea mouse was 1.24 pg, spiny crab 7.76 pg, starfish 1.52 pg and sea urchin 1.08 pg


Abnormal regulation of renin‐angiotensin system and increased level of oxidative stress have been implicated in renal/cardiovascular diseases associated with obesity. Earlier, we have shown that Angiotensin II AT1 receptor activity causes greater antinatriuresis via enhanced stimulation of tubular Na,K‐ATPase (NKA) in obese Zucker rats. The present study investigated the role of NAD(P)H oxidase in the enhanced AT1 receptor function in obese Zucker rats. Lean and obese Zucker rats were given NAD(P)H oxidase inhibitor, apocynin (3.5 μg/kg/min; i.v infusion) and/or AT1 receptor antagonist, candesartan (100 μg/kg; i.v bolus). Pretreatment with apocynin completely abolished candesartan‐induced diuresis/natriuresis in obese Zucker rats. In lean Zucker rats, apocynin alone increased diuresis/natriuresis and had an additive effect on diuresis/natriuresis when given along with candesartan. The blood pressure and GFR remained unchanged during drug treatment indicating a tubular effect. Apocynin treatment abolished and brought the AngII‐stimulated NKA activity below the basal activity in the isolated proximal tubules of obese Zucker rats. The data suggest NAD(P)H oxidase as an antinatriuretic molecule that switches to AT1 receptor signaling in the proximal tubules of obese Zucker rats and thereby contributes to the enhanced antinatriuresis.

The experimental platform designed in this paper can simulate process of the ATL machine, including variable rates and forces the composite prepreg tape laid up. Thanks to the closed loops, the platform is able to ensure the accuracy of the rate and force. As the control unit of the apparatus, PLC has a capacity to deal with signals to meet the needs of the apparatus, such as controlling the rate and the force the prepreg tape laid up and the safety of the platform when wrong operations occur.

Transportation studies in unidirectional waves are usually thought to provide a conservative approach to the design of jacket structures and their sea-fastenings. Model tests in multidirectional waves have, however, shown that the presence of directional spread sometimes increases motions, accelerations, and loads. This conclusion is supported by computer calculations using the NMI Wave diffraction and motions program, and can largely be explained by linear seakeeping theory. Several distinct causes have been identified.


3National program to fight against human African trypanosomiasis, Moundou, Chad. 4 OMS, Equipe Inter-Pays, Libreville, Gabon. 5 Association against Trypanosomiasis in Africa (ATA), Château de Brives, 39700 Lavans-Saint Lupicin, France. Accepted 18 December, 2012 Sleeping sickness is a vector-borne parasitic disease with variable, non-specific and inconstant symptoms. Thus, clinical signs are insufficient for diagnosis. Definite diagnosis relies on evidence demonstration of trypanosome in body fluids through parasitological techniques. For reasons related to costs, workload and technical incapacities, these technics are not always performed and sleeping sickness examination is thus limited to serological and clinical investigations. We report a false alarm due to incorrect diagnosis about a sudden outbreak of sleeping sickness in a focus under control. This report shows that inadequate diagnosis methods can lead to downward and upward errors in the prevalence of a disease. There is a need to reinforce material and technical capacities of health centers in endemic areas.


Abstract Alluvial and fluvial fans are the most widespread depositional landforms bordering the margins of long-lived highland regions and actively subsiding continental basins, across a broad spectrum of tectonic and climatic settings. Their significance is relevant not only to the local morphodynamics of mountain regions and proximal basinal sectors, but also to the long-term evolution of sediment-routing systems, affecting the propagation of stratigraphic signals of environmental change and the preservation potential of stratal successions over much larger spatial scales than those they occupy. Subaerial fan systems archive information on the palaeoclimate, local tectonic history and landscape response to various allogenic factors, although our ability to decipher such information is still limited. Early recognition of alluvial fans dates from the late nineteenth century, but a coordinated research community on these systems has been active only over the last few decades and the full relevance of fluvial fan systems to the geomorphology of present day continental basins and to the interpretation of ancient stratigraphic successions has been convincingly demonstrated only over the last decade. This introductory chapter summarizes advances in our knowledge of alluvial and fluvial fans, identifies potential new lines of future inquiry, and presents the contributions to this volume in the context of the current state of research.


6-PhenyI-, 2-methyl-6-phenyl-, and 2,6-diphenyl-4-pyrimidinylidenemalononitrile in acetic acid react with HN03 to form the corresponding 4-ethoxycarbonylpyrimidines in high yields after treatment of the intermediate product with ethanol. Under the same conditions 6-methyl-2-phenyl-4pyrimidinylidenemalononitrile yields 6-methyl-5-nitro-4-ethoxycarbonylpyrimidine whereas 2-phenyl-4pyrimidinylidenemalononitrile gives a mixture of 2-phenyl-4-ethoxycarbonyland 5-nitro-2-phenyl-4ethoxycarbonylpyrimidine.


COMMUNITIESTell Tchaikovsky the News: Rock 'n' Roll, the Labor Question, and the Musicians' Union, 1942-1968. By Michael James Roberts. Durham, NC: Duke University Press, 2014. [xv, 254 p. ISBN 9780822354635 (hardcover), $84.95; ISBN 9780822354758 (paperback), $23.95; (e-book), various.] Photographs, bibliography, index.The labor of music has recently gained new prominence in academic circles, and Michael James Roberts's Tell Tchaikovsky the News: Rock 'n' Roll, The Labor Question, and the Musicians' Union, 1942-1968 is a welcome addition to this discussion. Roberts examines archived records of the American Federation of Musicians (AFM), as well as popular press discussions from the period covered, to situate rock 'n' roll within the context of class and race struggles. The result is a compelling account of rock 'n' roll as bound up in the turmoil of the time. Roberts pays particular attention to the impact of recorded sound on the AFM and its attempts to come to terms with rock 'n' roll's successful development of this medium. This book will add to any discussion on intersections between music, labor, and aesthetics, especially for students newly interested in rock 'n' roll.Roberts's primary argument is that the AFM's tendency toward elitist anti-rock and anti-recording attitudes undermined its strength at the bargaining table. Through a Marxist analysis of economics and cultural products, Roberts traces the conflicting pressures that created rock 'n' roll and that contributed to its reception as a deviant musical genre. Crucially, Roberts attends to both the class pressures between whites and blacks and among black musicians themselves in his study. The result is a rich account of class struggle that adds nuance to the story of rock's place in American history.Roberts begins with a thorough rehashing of the AFM's struggle to deal with the proliferation of recorded music in the 1930s. AFM President Joseph Weber responded to the loss of union jobs to recordings with an expensive publicity campaign designed to persuade the public that recordings were less desirable than live musicians. This campaign explicitly reinforced high/low divisions between classical music and various popular forms associated with race records, such as rhythm and blues and hillbilly music. In comparison, James Petrillo, head of the Chicago AFM, negotiated better pay for musicians and fought successfully against the use of recordings by threatening mass strikes. After other AFM locals adopted similar tactics, Weber decided to retire, and Petrillo became president of the AFM nationwide. Petrillo actively argued against high/low divisions and regarded all working musicians, regardless of genre, as potential AFM members. Petrillo went on to organize a general strike on recording sessions in 1941, which led to a multiyear showdown between the AFM and the major record labels. By 1944, all of the labels had given in to Petrillo's demands. Roberts argues convincingly that Petrillo's inclusive attitude toward musical genres was a major factor in his overall success.Chapter 2 situates rhythm and blues (R&B) as part of the class conflicts of the 1940s and 1950s. Key figures including Louis Jordan, Little Richard, Chuck Berry, and others, drew on rural blues, big-band swing, and honky tonk to give sound to the strayers of working-class life. Central to this was the devilment of performative gestures-bright suits, dancing, and comedic lyrics and movement-that became, later, part of rock 'n' roll in general. Here, Roberts draws on Theodor Adorno and Walter Benjamin to establish jump blues and honky tonk as the "counterlogic of labor" (p. 52). As Roberts's most compelling claim, this concept is meant to work against histories of rock that romanticize the "danger" associated with the genre. Placing rock in the context of World War II, labor conflict, and racial tensions allows Roberts to portray R&B and rock as sounding out the noisiness of working-class life (e. …

The rhizome crude extract of Canna indica L. has been studied on its inhibitory effect on the growth of Staphylococcus aureus and Escherichia coli using KirbyBauer method. The rhizome was collected from different geographical locations namely: Metro Manila, Kadiwa, and Tagaytay with different treatments namely: T25, T50, T75 concentrations and one positive control group Ciprofloxacin. Different concentration including the positive control was placed in a nutrient agar plate with inoculated S. aureus and E. coli in separate plates. After 24 hours of incubation, the zone of inhibition was observed and measured using a vernier caliper. Rhizome crude extract taken from Metro Manila at treatment seventy-five percent concentration has the greatest inhibition zone recorded on S. aureus (4.78mm) and E. coli (4.33mm). Rhizome crude extract taken from Tagaytay has the least inhibition zone on S. aureus (0.67mm) at twenty-five percent concentration, and had no inhibitory effect on E. coli at seventy-five percent concentration. In conclusion, rhizome crude extract of Canna indica L. has minimal inhibitory effect against S. aureus and E. coli. Different treatment concentrations and geographical location of the rhizome crude extract are significantly different.


Meteorologists have developed a way of obtaining a velocity field V that satisfies the incompressible-flow continuity equation ∇ · V=0 in a bounded domain Ω, starting from a finite set of data {V$_{true}$(x$_k$)}$_{k=1}^{N}$ measured in Ω. In this work a mathematical framework of the scheme, is given. The approach can be extended to consider data provided by experimental methods such as the so-called particle image velocimetry technique. The viability of the scheme is tested with synthetic data from analytic solutions of the two-dimensional version of the equation ∇· V=0. Numerical examples show that the scheme can yield an accurate approximation V of the true velocity field V$_{true}$.

Ringed protoplanetary disks, in the Class II phase of low-mass star formation when the envelope has mostly dispersed, have been found in abundance in recent years with high-resolution ALMA observations. These ringed disks have been often interpreted as evidence of ongoing planet formation. In the younger Class 0 and I phases there are few examples of high resolution dust disk observations due to the challenge of the dense envelope surrounding the disk, and more often than not reveal spiral-like structures. However, these embedded stages may be when the first steps of planet formation occur, and studying ringed structures in these phases will constrain the initial conditions of planet formation. We have used ALMA 1.3 mm long-baseline dust continuum observations to study the Class I protostar IRS 63 with 7 au resolution and expose the detailed physical structure of a Class I disk. The ALMA data indicate that concentric dust rings are present in the disk, revealing IRS 63 is the youngest-known protostellar disk with multiple ringed dust substructures and demonstrating that these features are already present in the Class I phase. The dust ring structures could arise via several mechanisms including rapid pebble growth near snowlines, magnetorotational instabilities, asymmetric accretion from the envelope to disk, or planet-disk interactions carving gaps in the disk. Even if planets have not yet formed, dust rings in disks at such an early evolutionary stage could provide a stable environment for long enough time scales to grow planets.


This post hoc exploratory analysis of Lifestyle Interventions and Independence for Elders (LIFE) trial data examines the association between the trial's physical activity intervention and sedentary time in older adults.


Mondini dysplasia was found by high resolution CT scanning of the temporal bones in 13 patients with congenital hearing loss. High resolution CT scanning of the temporal bone has made it possible to diagnose Mondini dysplasia much easier than before. However diagnosis of slight hypoplasia of the inner ear is still difficult. Assessment of hyperplasia of the interscalar septum in front of the stapes is a significant sign in the diagnosis of slight hypoplasia of cochlea. This finding may indicate dysplasia of the modiolus. The axial section of CT scanning is most useful in demonstrating the inner ear and slice thickness of less than 2 mm is optimum thickness that can effectively demonstrate the inner ear changes.


Background: Copeptin , a neurohormone, has been identified lately as a biomarker for prediction of metabolic syndrome in recent few years. In this pilot study, we evaluated levels of Copeptin in patients of Type 2 Diabetes mellitus ( n =41). Materials and methods: The study was carried out on Type 2 Diabetes mellitus patients ( n =41) of either sex. The copeptin levels were estimated using Human C- Reactive protein ELISA Kit, For serum, plasma, cell culture supernatants and urine (Sigma Aldrich Co, LLC)Human Copeptin ELISA Kit (Mybiosource, Antibody. Protein. ELISA Kit). Results: We found that the levels of Copeptin ranged from 0.488 to 9.36 (median 1.18; mean 1.82) pmol/l in our cohort. There was no significant difference observed between Copeptin levels of patients with normal Body Mass Index (BMI) and those with higher than normal BMI. Conclusion: The present study reports for first time the values of Copeptin in Indian patients. However, there is need to estimate the levels in larger sample size to establish its utility and importance in Indian patients with metabolic syndrome.


Mermithid nematodes are parasites of a wide range of invertebrates but information on their life history associated with their hosts is limited. Here we investigated mermithids isolated from the shield bug Parastrachia japonensis , a univoltine and sedentary insect, to understand their life cycles and the effect of parasitism on their host. Mermithids were detected from 5 out of 6 sampling locations with infection ratios of 0 % to 16 . 1 %. Most cases were monoparasitism but hyperparasitism was also observed. Mermithids emerged from the host late in the final host nymphal stage and the host immediately died after the mermithid emerged. No mermithid was detected from adults in the present survey. There was no correlation between weights of hosts and mermithids. In addition, there was no difference in the weights between the nematode-infected and non-infected hosts, and apparent morphological and behavioral changes were not observed in the nematode-infected nymphs, suggesting that nematode parasitism does not affect the host before the nematodes emerge. Phylogenetic analysis revealed that two species of mermithids parasitize P. japonensis . Nematol. Res. 50 ( 1 ), 1 – 7 . ( 2020 )


There is an old East Indian fable of a young man who went to see a wise man. The young man had a question - {open_quotes}How can I become rich and powerful?{close_quotes} The wise man paused for a moment then asked a question in return - {open_quotes}How can you swallow an elephant?{close_quotes} The young man was astounded, {open_quotes}There is no way a man can swallow an elephant!{close_quotes} {open_quotes}Yes, there is,{close_quotes} replied the wise man, {open_quotes}You just have to do it one bite at a time.{close_quotes} Many large problems can only be handled the same way that an elephant is swallowed, one bite at a time. Global warming and other environmental problems are obviously of elephant-swallowing scale. Some have set a goal for our society of reducing atmospheric greenhouse gases, particularly carbon dioxide (CO{sub 2}), by 20%. The cost to accomplish this has been estimated to be about five trillion dollars! As big as this elephant is, I suspect that its size is understated, if all the factors involved are included. The proponents of the plan tell us that it is well worth the cost to save the world. Therein lies another elephant-style problem.


Sir, We read with great interest regarding a case report clofazimine‐induced methemoglobinemia: A rare incidence by Ahmed Asif et al.[1] The authors have very nicely pictured out the case with the utmost management that prevent the patient to recover from the dangerous situation. The authors have managed the acute ingestion of several tablets of suspected clofazimine capsules that have resulted in methemoglobinemia. This case report is an important signal regarding the suspected clofazimine overdosage that was not even documented in the drug information sources available with the manufacturer.[2] Being a country harboring 60% of leprosy cases globally[3] and getting treated with multibacillary blister pack, this type of adverse event should be carefully notified as clofazimine is the major component of the blister calendar pack.

Abstract : This report presents the results of a geophysical study performed to determine the location of buried utilities beneath or in the vicinity of the levees on the south shore of Lake Pontchartrain approximately 8 km (5 miles) north of downtown New Orleans, LA. There was concern that utilities located beneath or buried near the toe of the levees could act as a water conduit during flooding events. If a water-filled utility fails, it is possible that it may cause the levee to fail either by piping material from within the levee or cause slope stability problems. It is also possible that buried utilities can act as potential seepage paths through the levee during high water events. In this case, the buried pipe would not have to fail to cause a problem. The utilities needed to be accurately located so that they could be rerouted, removed, or abandoned and grouted-in. Electromagnetic, total field magnetic, and ground penetrating radar systems were assessed to determine the best method for detecting the buried utilities in this area. The Geonics EM31 electromagnetic induction instrument was considered the most effective for detecting the utilities. EM31 anomalies, presumed to be the locations of buried utilities, were mapped and their coordinates tabulated for further interrogation.


The Resource management in a grid environment is complex. Scheduling strategy plays an important role in the grid environment to schedule the user jobs, and dispatch them to appropriate grid resources. A good task scheduling method is essential to reduce the total time taken for job execution in the grid. In a grid environment, the jobs are processed at the grid resources in a fine-grained form that results in a low computation-communication ratio. So an efficient job grouping-based scheduling system is required to dynamically assemble the individual fine-grained jobs of an application into a group of jobs and then transmit these coarse-grained jobs to the grid resources. The objective of this paper is to develop a scheduling strategy using job groups that optimizes the utilization of processing capabilities of grid resource and reduces the total time taken to process user jobs.


The paper presents the research on the effectiveness of noise reduction of power plants using mufflers. Recent computational studies can be used in the construction of silencers in order to find the optimal solution on the basis of the degree of noise reduction, layout and economic considerations.

Changes of plasma vitellogenin (VTG) and glutamate pyruvate transaminase (GPT) were examined for determining whether hepatocyte was damaged during the process of VTG induction in the juvenile rockfish, Sebastes schlegeli exposed to exogenous estrogen (estradiol-17β, E₂). Rockfishes were intraperitoneally injected with E₂, (5 mg/kg B.W.) in 70% ethanol and plasma sampling were extracted at 0, I, 3, 6, 9, 12, 15 days after E₂ administraton. VTG and GPT were then analyzed by SDS-PAGE and Reitman-Frankel method, respectively. VTG band was detected at a molecular weight position of 175 kDa on Day 3 after E₂, administration. This band became more distinct at 6 days, but its was gradually thinned with time course, and not detected at 15 days. GPT was suddenly increased at I days after E₂ administration and highest GPT was detected at 3 days. However, GPT was gradually decreased with time-course as the change of VTG. These results suggest that the process of VTG induction by exogenous E₂ damage to hepatocyte, and plasma GPT was temporarily increased in the juvenile rockfish.

This paper reports Glinus lotoides L. (Molluginaceae) and Senna occidentalis L. (Fabaceae) as two new records to the flora of the United Arab Emirates (UAE). In the UAE, G. lotoides grows in the seasonally inundated land when the water recedes and soils have high clay contents. This is the only representative species of the genus Glinus in the UAE. Hence, we added a new genus to the country's flora. Senna occidentalis was recorded from Wadi Al-Ain with ca. 15 individuals in its population. This species is considered as a weed elsewhere, so, there should be further assessments in order to monitor naturalization potential in its new localities in the UAE. The general distribution of the newly recorded species, habitat preferences and taxonomy with a map of localities in the UAE are presented. The occurrence of both species in different places in the UAE calls for further investigation and more extensive field studies to explore the country's genetic resources.

Metzler describes the theoretical bases and a general model for integrating teacher effectiveness research with sys tematic observation to evaluate physical education teaching. The ability to de lineate desirable teaching skills and to monitor preservice teachers' acquisition of those skills represents a new potential for improving theteaching of motor play and fitness. The author argues against holding physical educators accountable for student achievement until some per vasive instructional constraints are eased. The suggestion is made, how ever, that physical educators should be able to "account for" their pedagogical practices.


Oceanographic surveying has been one of the key missions of the Chinese National Antarctic Research Expeditionsince 1984. Using the field data obtained in these surveys and the results from remote sensing and numerical models, Chinesephysical oceanographers have investigated the water masses, fronts and circulation patterns in the Southern Ocean. The results ofnearly 30 years of research are summarized in this paper. Most oceanographic observations by Chinese researchers have been conductedin Prydz Bay and the adjacent seas. CTD (Conductivity Temperature and Depth) data, collected during the past 20 years,have been applied to study several features of the water masses in this region: The spatial variation of warm summer surface water,the northward extension of shelf water, the flow of ice shelf water from the cavity beneath the Amery Ice Shelf, the upwelling ofthe Circumpolar Deep Water, and the formation of the Antarctic Bottom Water. The circulation and its dynamic factors have beenanalyzed with dynamic heights calculated from CTD data as well as by numerical models. The structure and strength of the frontsin the southeast Indian Ocean and the Drake Passage were investigated with underway XBT/XCTD (Expendable Bathythermograph/Expendable CTD) and ADCP (Acoustic Doppler Current Profiler) data. Their interannual variations have been determinedand the factors of influence, especially the atmospheric forcing and mesoscale oceanic processes, were studied using remote sensingdata. The dynamic mechanism of the Antarctic Circumpolar Current (ACC) was analyzed by theoretical models. The transportand pattern of the ACC have been well reproduced by coupled sea ice-ocean models. Additional details of ACC variability wereidentified based on satellite altimeter data. The response of the ACC to climate change was studied using reanalysis data. Prospectsfor future research are presented at the end of this paper.


BACKGROUND: Medical students are frequently described as stressed in comparison with general population.1,2 Particularly examinations are a major cause of stress.3 High level of stress may have adverse effect on academic achievement. However there is a deficit of information regarding the interrelationship of stress and academic performance in medical students. The present study adds to the literature of the level of stress during examination and its impact on performance in a cohort of first year medical students. The study also discusses the areas where medical students are more stressful, effects of stress, student's adaptation styles, and intervention measures to deal with stress, as it is believed that healthy medical students are likely to become healthy doctors who can then be model and promote healthy lifestyles with their patients.4 AIMS AND OBJECTIVES: 1. To determine the effect of stress measured by self-evaluation questionnaire. 2. Impact of examination stress on the academic performance of first year medical students. 3. To study effect of premenstrual stress on autonomic function. MATERIAL AND METHODS: A prospective cohort study was conducted on medical students to determine the examination stress measured by anxiety questionnaire and autonomic function tests. One hundred medical students studying in first academic year admitted for the first year during 2011-2012 in S.P. Medical College, Bikaner. Stress was measured during first terminal examination since it was the first major examination faced by the students after entering into the professional course. SUMMARY AND CONCLUSION: In consort with previous research, the examination of first year medical students is stressful enough to affect the performance adversely. Since stress around examinations is strongly predicting the academic achievement, students should be exposed to stress management techniques to help prevent the known high consequences. INTRODUCTION: Medical education is long and at some instances tiring. The student often realizes about his/her future/career. When his fellow colleagues have started their career, got married, got issues, developed bank balance and so on – so forth, he has just not started even. This creates many times stress among medical students. This also explains the fact that at present time sections of science biology at school level are lying vacant. The students are coming from school standard (after 12th class) and more than 90% are from Hindi medium. They are unable to understand English language teaching in medical institutions and in such atmosphere when they know that they have to face an examination here, they go under stress.

Observational data, especially astrophysical data, is often limited by uneven sampling that arises due to lack of observations for a variety of reasons. Such inadvertent gaps are usually smoothed over using interpolation techniques. However the smoothing techniques can introduce artificial effects, especially when non-linear analysis is undertaken. We investigate how uneven sampling can affect the computed values of correlation dimension of the system, without using any interpolation. For this we introduce gaps artificially in synthetic data derived from standard chaotic systems, like the Rossler and Lorenz, with frequency of occurrence and size of missing data drawn from Gaussian distributions. Then we study the changes in correlation dimension with change in the distributions of frequency of gaps introduced and size of data removed. We find that for a considerable range of gap frequency and size, the value of correlation dimension is not significantly affected. This would mean that in such specific cases, the calculated values can still be reliable and acceptable. Thus our study introduces a method of checking the reliability of computed correlation dimension values by calculating the distribution of gaps with respect to its size and frequency and comparing with the standard plots presented in the paper. This is illustrated for real world examples of the data from three variable stars, R Scuti, U Monocerotis and SU Tauri. We also demonstrate how a cubic spline interpolation can cause an unevenly sampled noisy data to be misinterpreted as being chaotic in origin. This is demonstrated for the non chaotic light curve of variable star SS Cygni, which gives a saturated D2 value, when interpolated using a cubic spline.


The posterior Craḿer-Rao bound on the mean square error in tracking the bearing, bearing rate, and power level of a narrowband source is developed. The formulation uses a linear process model with additive noise and a general nonlinear measurement model, where the measurements are the sensor array data. The joint Bayesian Cram ér-Rao bound on the state variables over the entire observation interval is formulated and a recursive bound on the state variables as a function of time is derived based on the nonlinear filtering bound developed by Tichavsky et al (1998) and analyzed by Ristic et al (2004). The bound is shown to have the same form as when the measurements are bearing and power estimates with variance equal to the deterministic Cram ér-Rao bound for a single data snapshot. The bound is compared against simulated performance of the maximum a posteriori penalty function (MAP-PF) tracking algorithm developed in Zarnich et al (2001).


Abstract "Que Marianne était jolie," a well-known French popular song of the 1970s, is a space of possibilities, a realm of "cross-cultural events," where interpretation is deeply rooted in French history and societal evolution. The main complexity in deciphering the coded meaning of its lyrics is to analyze the source space and time (first element of the binary code: the revolutionary codification), and to view how the same symbols were "appropriated, translated, rehistorized, and read anew" in the song (second element of the binary code: the republican codification). The use of visual art as an interpretative tool here aims at better decoding and reading the contexts, the concepts and the shifts in meanings, and ensuring we can comprehend the main character, plot, and settings implicit in this pop song.


This paper investigates the relation between employment protection and corporate liquidity management (i.e., cash holding and cash saving decisions). Theory suggests that employment protection increases firms' labor adjustment costs. We use difference-in-difference estimation method exploiting changes in employment protection laws as a source of variation in labor adjustment costs in 20 countries over the period 1990-2007. We find that, in response to an increase in employment protection, firms increase their cash buffers and propensities to save cash from the funds raised internally and externally. The effect is stronger for firms with relatively small size, high cash flow volatility, and high labor intensity. Overall, our findings suggest that firms' precautionary motives for cash savings increase as labor adjustment costs and therefore operating leverage increases.

The notion of geometric phase has been recently introduced to analyze the quantum phase transitions of many-body systems from the geometrical perspective. In this work, we study the geometric phase of the ground state for an inhomogeneous period-two anisotropic XY model in a transverse field. This model encompasses a group of familiar spin models as its special cases and shows a richer critical behavior. The exact solution is obtained by mapping on a fermionic system through the Jordan-Wigner transformation and constructing the relevant canonical transformation to realize the diagonalization of the Hamiltonian coupled in the k space. The results show that there may exist more than one quantum phase transition point at some parameter regions and these transition points correspond to the divergence or extremum properties of the Berry curvature.

Purpose
Epoxy resins are widely used in a variety of engineering applications, including composite wind turbine blades used in the renewable energy industry, highly complex structural components for aircraft, paints, coatings, industrial tooling, biomedical systems, adhesives, electronics and automotive. Epoxies' low fracture toughness is one of the key obstacles preventing its adoption in a wider range of applications. To address epoxy's low fracture toughness, this paper aims to examine the roles of intra-ply hybridization and nano reinforcing.

Design/methodology/approach
This paper investigates the role of intra-ply hybridization of glass-carbon woven fibers and adding 0.8 wt.% of multiwall carbon nanotube (MWCNT) nano reinforcement to overcome the low fracture toughness of epoxy. A bending test is used to calculate the composites elastic parameters, and a notched sample three-point bending test is used to show crack behavior in addition to using materials characterization methods to reveal the effect of the MWCNT on structure, bonding, glass transition temperature (Tg) and dispersion of MWCNT in the matrix. Furthermore, this paper suggests using the finite element method to overcome the difficulty in calculating the crack extension.

Findings
Intra-ply hybridization and MWCNT reinforcement decrease the crack extension of epoxy with time. The inclusion of high-strength carbon fiber increased the fracture toughness of glass composite. Furthermore, the existence of MWCNT in the surrounding area of the notch in epoxy composites hinders crack propagation and provides stiffness at the interface by bridging the crack and eventually enhancing its fracture toughness.

Originality/value
Studying the role of intra-ply hybridization of glass-carbon woven fibers and adding 0.8 wt.% of MWCNT nano reinforcement to overcome the low fracture toughness of epoxy. Additionally, this research recommends using the finite element method to overcome the challenge of computing the crack extension.

Lipoma is a tumor of soft tissue with rare occurrence in oral cavity accounting for only 1% to 4% of benign oral tumors. Most common sites of involvement are buccal mucosa, tongue and floor of the mouth with typical presentation of asymptomatic, soft, smooth-surfaced, nodular and yellowish mass. Histopathologically, a classical lipoma resembles normal adipose tissue and it has multiple variants which are less commonly seen except fibrolipoma. The article presents a case report of a relatively large oral classical lipoma in a 60 year-old-male on a rare site, i.e., mandibular buccal vestibule, along with review of literature and special emphasis on its various histopathological variants

In the Husnjakovo rock-shelter near Krapina, northern Yugoslavia Gor janovic-Kramberger excavated in 1899 a number of Neandertal lower limb remains. Consisting of fragments of ossa coxae, femora and tibiae and relatively complete patellae, fibulae and pedal bones, the Krapina lower limb bones have been largely un studied. An inventory of the fossils indicates the presence of one of the richest European hominid samples from the early Wiirm. Despite their generally fragmentary nature, these remains can provide invaluable morphological and metrical data on Neandertal lower limb anatomy. Associations of the bones by individual according to morphology and size suggest that at least 13 and probably between 20 and 30 indivi duals are represented by the Krapina lower limb remains.


This paper is concerned with the efficient computation of the ubiquitous electron repulsion integral in molecular quantum mechanics. Differences and similarities in organization of existing Gaussian integral programs are discussed, and a new strategy is developed. An analysis based on the theory of orthogonal polynomials yields a general formula for basis functions of arbitrarily high angular momentum. (ηiηj∥ηkηl) = Σα=1,nIx(uα) Iy(uα) I*z(uα) By computing a large block of integrals concurrently, the same I factors may be used for many different integrals. This method is computationally simple and numerically well behaved. It has been incorporated into a new molecular SCF program HONDO. Preliminary tests indicate that it is competitive with existing methods especially for highly angularly dependent functions.


Particles of spin 1/2 and 1 in external Abelian monopole field are considered. P-inversion-like operatorsˆN , commuting with the respective Hamiltonians, are constructed: ˆ N bisp. is diagonalized onto the relevant wave functions, whereasˆN vect. does not. Such a paradox is rationalized through noting that both these operators are not self-conjugate. It is shown that any N-parity selection rules cannot be produced. Non-Abelian problems for doublets of spin 1/2 and 1 particles are considered; corresponding discrete operators are self-conjugate and selection rules are available.
