Abstract We present a pilot study on the nearby massive galaxy NGC 1291, in which we aim to constrain the dark matter in the inner regions, by obtaining a dynamical determination of the disc mass-to-light ratio (M/L). To this aim, we model the bar-induced dust lanes in the galaxy, using hydrodynamic gas response simulations. The models have three free parameters, the M/L of the disc, the bar pattern speed and the disc height function. We explore the parameter space to find the best fit models, i.e. those in which the morphology of the shocks in the gas simulations matches the observed dust lanes. The best-fit models suggest that the M/L of NGC 1291 agrees with that predicted by stellar population synthesis models in the near-infrared (≈ 0.6 M ⊙/L ⊙), which leads to a borderline maximum disc for this galaxy. The bar rotates fast, with corotation radius ⩽ 1.4 times the bar length. Additionally, we find that the height function has a significant effect on the results, and can bias them towards lower or higher M/L.


Reactions of several metal cluster complexes with [O{Au(PPh3)}3][BF4] in the presence of [ppn]+ salts [ppn =(Ph3P)2N] have given derivatives containing two Au(PPh3) moieties in which an Au–Au bond may or may not be present; in the title complex, an unusual Au–C interaction is present, which may model an intermediate stage in the addition of H2[isolobal with Au2(PPh3)2] to the parent Fe2Ir acetylide cluster, which reaction affords the hydrido-vinylidene complex Fe2Ir(µ-H)(µ3-CCHPh)(CO)8(PPh3).


AbstractA detailed experimental study of the development of plastic flow has been made in a non-cavitating superplastic alloy (wrought Pb-Cd eutectic). The behaviour has been analysed in terms of two instabilities, the first corresponding to the development of measurable external necks and the second to the rapid growth of one neck to cause plastic rupture.

Drain leakage current degradation at zero V/sub gs/ in a hot carrier stressed n-MOSFET is measured and modeled. The dependences of drain leakage current on supply voltage and temperature are characterized. In modeling, various drain leakage current mechanisms including drain-to-source subthreshold leakage current, band-to-band tunneling current and interface trap assisted leakage current are taken into account. The results show that interface trap induced leakage current appears to be a dominant drain leakage mechanism as the supply voltage is scaled below 3.0 V. Drain leakage current degradation by orders of magnitude has been observed due to hot carrier stress.

and differences in Moses' characterization in the Synoptics and in Second Temple Jewish literature. In ch. 5, Harstine discusses Greco-Roman literature in order to demonstrate that the iconic figure of Homer has been appropriated in the same manner as Moses. This suggests that Greek readers would understand the function of Moses' character in John. Overall, the book is insightful. This is an excellent supplemental text in the classroom for the study of John or the characterization of Moses in Judaism and early Christianity. The benefits far outweigh the few shortcomings. Harstine has addressed an aspect of the Gospel of John that many have overlooked.


The solubilities of the inert gases were measured in pure water and in sea water within the temperature range from 0 to 25 un. Concent 85% C. Comparison of the values in pure water and of the solubilities of argon in sea water with data obtained by other authors suggest that the measurements are reliable within the quoted limits of error. The behavior of the inert gases is expressed in a series of regularities which are also graphically shown. (auth)

From the dawn of time, all derivatives of the classic Hindley-Milner type system have supported implicit generalisation of local let-bindings. Yet, as we will show, for more sophisticated type systems implicit let-generalisation imposes a disproportionate complexity burden. Moreover, it turns out that the feature is very seldom used, so we propose to eliminate it. The payoff is a substantial simplification, both of the specification of the type system, and of its implementation.


By-products of jackfruit, such as bark, mesocarp, central axis and seeds, are not used by industry. The seeds are used in human food in a rudimentary form in the form of boiled or roasted, while the shells and mesocarp are basically discarded or used in animal feed. The objective of the present study was to evaluate the potential of the pulp and jackfruit residues in the creation of a sustainable sweet. Two formulations of light creamy sweets were designed: F1 (control) containing only pulp (50%) and F2 containing 30% pulp and 20% mesocarp. Subsequently, three more creamy candy formulations were developed, F3, F4 and F5, which in addition to containing 30% pulp and 20% mesocarp, 5%, 10% and 15% of roasted jackfruit flour were added , in that order. These products were obtained in terms of physical-chemical and nutritional characterization, in addition to being subjected to sensory analysis and purchase intention in comparison to sweet with pulp alone. The results revealed that the use of mesocarp and jackfruit seed are viable alternatives in the preparation of sweets from a nutrit ional and sustainable point of view. This use of by-products contributes not only to the reduction of waste, but also to the greater supply of nutrients for human consumption.


Magnetoresistance (MR) and magnetothermoelectric power (MTEP) of iodine-doped single-walled carbon nanotubes (I@SWNT) under magnetic fields up to 14 T are investigated from room temperature (300 K) down to 1.6 K. Our results on resistivity and thermoelectricpower (TEP) in a zero magnetic field are similar to those reported by Grigorian et al. [Phys. Rev. Lett. 80, 5560 (1998)] The positive sign of the TEP values indicates that the majority of the carriers in the I@SWNT are holes. The broad enhancement of TEP at temperatures of 30\char21{}200 K shows quasilinear temperature dependence and is consistent with sharply varying density of states near the Fermi level with additional contribution from the spin-orbit scattering in the normal metallic characteristics of the I@SWNT. For $Tl7\text{ }\text{K}$, MR is negative and it decreases with ${H}^{2}$ followed by the ${H}^{1/2}$ dependence at around $H=2\text{ }\text{T}$ which is characteristic for the weak localization. In the range $7\text{ }\text{K}lTl70\text{ }\text{K}$, MR is positive at low magnetic field and becomes negative at higher magnetic field. The negative MR in the high magnetic fields decreases linearly. At $T\ensuremath{\ge}\ensuremath{\sim}100\text{ }\text{K}$, MR is positive up to 14 T, which could be the result of spin-orbit scattering in the I@SWNT. The MTEP decreases under magnetic field at $Tl90\text{ }\text{K}$. The reduction in MTEP is originated from the delocalization of electron wave functions under the magnetic field. At $Tg90\text{ }\text{K}$, the thermal fluctuation dominates the effect of magnetic fields resulting the MTEP to be the same as the zero magnetic field TEP.


A Penrose diagram is constructed for a spatially coherent black hole that smoothly begins an accretion, and then excretes symmetrically as measured by a distant observer, with the initial and final states described by a metric of the Minkowski form. Coordinate curves on the diagram are computationally derived. Causal relationships between spacetime regions are briefly discussed. The life cycle of the black hole demonstrably leaves asymptotic observers in an unaltered Minkowski spacetime of uniform conformal scale.

The removal ofUV radiation-induced pyrimidine dimers and (6-4) photoproducts as well as other bulky base adducts from the DNA of higher eukaryotes relies on the concerted action of about 30 proteins which excise base damage and restore the DNA to its native state. This process is known as nucleotide excision repair (NER), and the proteins involved are highly conserved throughout the eukaryotae. There are indications that the initial steps of NER are effected by a large preformed multi-protein complex comprising the RNA polymerase II transcription factor I1H (TFIIH) and other NER proteins known to be required for damage recognition and DNA incision. Humans with inactivating mutations in the genes encoding NER proteins suffer from the cancer-prone syndrome xeroderma pigmentosum (XP). In yeast, a mode of NER which is apparently coupled to transcription requires the activity of Rad26 protein, while transcription-independent NER requires the activity of the Rad7 and Radl6 proteins. Defects in transcription-dependent NER are associated with the human hereditary disorder Cockayne syndrome (CS).

Bionic polarization navigation has a broad variety of application in diverse fields for high reliability and strong robustness to interference, fundamental to which is the use of a polarization compass based on polarized light cues. Nevertheless, dramatical reduction of the orientation accuracy resulted from the noise in a measured angle of polarization (AoP) and the tilted angles of a polarization compass during operation gives imperative influence on navigation precision. Herein, we investigate how to improve the navigation accuracy effectively by the proposed comprehensive heading error processing technique for a polarization compass, where a novel denoising scheme is designed to eliminate the noise in AoP images directly by integrating the strength of iterative variance-stabilizing transformation (IVST) and adaptive soft interval thresholding (SIT) so as to compensate the following tilt-induced error accurately. Subsequently, a promising compensation approach inspired by efficient extreme learning machine (EELM) is introduced to correct the tilt-induced error caused by realistic execution. The AoP image denoising advance and the tilt-induced error modeling advance combine to produce remarkable performance gains on the heading error. Experimental results and comparisons with prior arts reveal that the proposed comprehensive heading error processing technique is highly appealing in terms of improving the orientation accuracy for a polarization compass with superiority to state-of-the-art alternatives.


The utility model relates to an inspection well cover with a protective screen, which comprises a base, a neck portion, a fixing ring and a well cover. The neck portion is formed by upwards extending the base, the fixing ring is positioned on the inner side of the neck portion, the well cover is supported on the fixing ring, the top surface of the well cover is leveled with the top surface of the neck portion, and a plurality of hangers are integrally formed on the inspection well cover and positioned on the inner wall of the fixing ring. The inspection well cover further includes the protective screen mounted on the hangers. The inspection well cover with a protective screen has the advantages of simple structure, convenient manufacturing, utilization and maintenance and capability of protecting safety of pedestrians and vehicles.


In this paper, we survey some recent trace inequalities for operators in Hilbert spaces that are connected to Schwarz's, Buzano's and Kato's inequalities and the reverses of Schwarz inequality known in the literature as Cassels' inequality and Shisha–Mond's inequality. Applications for some functionals that are naturally associated to some of these inequalities and for functions of operators defined by power series are given. Examples for fundamental functions such as the power, logarithmic, resolvent and exponential functions are provided as well.


ABSTRACT
 This paper examines the relationship between school closures during the Covid-19 pandemic and the ideology of intensive mothering through analysis of posts on lockdown learning in an online mothering community. It is argued that although the school closures seemed to constitute an endorsement and normalisation of intensive mothering ideology [Hays (1996). The Cultural Contradictions of Motherhood. New Haven: Yale University Press] by the machinery of government, and increased the pressure upon many women, some mothers resisted these expectations in this online forum. The online community served as a space in which intensive mothering expectations were articulated [Lehner-Mear (2020). "Good Mother, Bad Mother? Maternal Identities and Cyber-Agency in the Primary School Homework Debate." Gender and Education 33 (3): 285–305] but also offered an arena for cyber-agency, enabling women to express negative emotions, and normalising the rejection of expert constructions of mothering.


The increasing demand of the protection of an enterprise information system has become one of the major priority and commitment of the executive committee and the board of directors. Risk management aligned with IT resources consists of a strong result which is called Information Security Governance (ISG) or the 4th wave. This article will present a multi-agent system which automates the ISG process on the behalf of the top management. The originality consists on using multi-agents systems including the 4th wave which has never been done before in other scientific works. It would result on the assessment of a new model merging the development of ISG, compliance and risk management in one framework which demonstrates the pivotal role of handling security risks in a company. In this context, we must address security with highly precautions; we should not only focus on the technical problems of security but also to their decisional part which involves the board and top management. Following the PDCA approach, we will demonstrate how our model can use international standards and methods to support organization's information systems.

Background: Prolongation of P‐wave times and increase of P‐wave dispersion (PWD) were shown to be independent predictors of atrial fibrillation (AF). Angiotensin II receptor blockers (AARBs) and angiotensin‐converting enzyme inhibitors (ACEIs) have beneficial effects on atrial conduction times. However, there are not enough data about the comparative effects of those drugs onPWD.


Many Web based learning experiences fail due to bad or absent support. LMSs (learning management systems) must incorporate mechanisms for real time monitoring of the involvement of each participant in a course, allowing the detection of deviations to the scheduled activities, enabling the correction of these deviations (Ramos et al., 2001). The principal standardization projects in the area do not cover this type of aspects. Those projects are mainly focused on contents and their delivery to the learners participating in the courses. This article describes a proposal of a reference model and functionalities towards a specification of a layer for real-time management of user interactions with SCORM (sharable content object reference model) compliant LMSs


In order to improve the safety of potentially hazardous situations such as "hot" disconnections of equipment or deteriorated connections, a deeper knowledge of the characteristics of the arcs thus produced and their subsequent damage to contact materials, insulating and wiring, is needed. Numerous studies have been performed on DC arcs as they appear in automotive applications. There is however, a strong need to study arcs in the domain of alternating current, in order to understand their consequences to safety and reliability in domestic applications. The purpose of this study is to extend our knowledge of AC-arc characteristics and consequences (e.g. risk of fire ignition) in order to improve the reliability of security devices such as arc fault circuit interrupters (AFCI). Conditions when arcs could initiate and reinitiate are determined, for a voltage of 220V (50Hz), a current from 1A to 4A, electrodes made with copper or graphite and gaps from 10µm to 1000µm. The conclusion of this work is that arcs produced by graphite electrodes present some characteristics which differ significantly from metallic electrode arcs, especially regarding ignition and re-ignition capability. This behavior should be taken into count for safety considerations.


Background—In heart failure and reduced ejection fraction, the prognostic role of heart rate (HR) in atrial fibrillation (AF) is unknown and the effectiveness of &bgr;-blockers has recently been questioned in AF. Methods and Results—A total of 18 858 patients with heart failure and reduced ejection fraction registered with Swedish Heart Failure Registry were included in this study: patients with sinus rhythm (SR; n=11 466) and patients with AF (n=7392). The outcome measure was all-cause mortality. Compared with HR ⩽60 beats per minute, the adjusted hazard ratios for mortality in SR were 1.26 for HR=61 to 70 beats per minute, 1.37 for HR=71 to 80 beats per minute, 1.52 for HR=81 to 90 beats per minute, 1.63 for HR=91 to 100 beats per minute, and 2.69 for HR >100 beats per minute. However, in AF, the hazard ratio increased only for HR >100 beats per minute (1.30; P=0.001). &bgr;-blocker use was associated with reduced mortality in SR (hazard ratio, 0.77; P=0.011) and in AF (hazard ratio, 0·71; P<0.001). For &bgr;-blocker use in SR, the hazard ratio gradually increased with HR increment, whereas in AF, the hazard ratio significantly increased only for HR >100 beats per minute (1.29; P=0.003) compared with HR ⩽60 beats per minute. Conclusions—In patients with heart failure and reduced ejection fraction, a higher HR was associated with increased mortality in SR, but in AF, this is true only for HR >100 beats per minute. &bgr;-blocker use was associated with reduced mortality both in SR and in AF.


How do you find the sources to write the history of the health of a city, particularly for the late twentieth century and into the digital age? This article explores this challenge in the case of the city of Bristol in the United Kingdom during the period from the creation of the National Health Service (NHS) in 1948, through the transfer of the public health function from local government to the NHS in 1974 and up until the return of public health back to local government in 2013. The aims of the article are to scope the extant paper and digital official and academic documentary sources for the history of public health in the city, to critically assess the availability and completeness of the sources and to reflect on the challenges and opportunities of integrating earlier paper records with more recent digital ones.


The hatch coaming,hatch cover and its guiding device of the 8530 TEU container ship are simplified. Synthetically applying CAE software,the contact-impact process between the lift-away hatch cover and its guiding device is emulated. Through simulation analysis of dynamics,the parameters such as the "maximum impact force vs. impact velocity,maximum displacement of the guiding device as well as the maximum effective stress are obtained. The results of impact analysis could supply reference to the design and analysis of such structure,and the computational model could be used to do deeper analysis according to different needs


The lengths of the digital bones of the foreand hind-limbs obtained post mortem from 40 cattle of different ages were measured using digital radiographs. The lengths of the individual digital bones and the overall length of the digit were determined using computer software. The lateral metacarpal/metatarsal condyle, and lateral P1 and P2 were significantly longer than their medial counterparts, whereas P3 of the medial digit was longer than its lateral partner. Measured from the cannon bone epiphysis to the tip of the pedal bone, the mean increased length of the lateral digit was 0.8 mm in the foreand 1.5 mm in the hind-limb. When the lengths of the digital bones were summed, the mean length of the lateral digit was 1.8 mm longer in the fore-limb and 2.1 mm longer in the hindlimb. Based on these findings, it can be concluded that the lengths of the paired digits differ in cattle. The majority of cattle have longer lateral digits in the foreand hind-limbs. This asymmetry might explain why the lateral hind-limb claws are predisposed to sole ulcers on hard surfaces. In the hind-limbs, the impact is transferred from the pelvis directly to the longer lateral digit. In the fore-limb claws, the tenomuscular attachment to the trunk may be involved in a more even weight distribution and in a shift of weight to the medial claw. Length asymmetry of the bovine digits 1 2 E. Muggli , C. Sauter-Louis , U. Braun , K.

To date, attenuation correction of gated PET emission data remains a challenge. Joint activity and attenuation estimation methods may contribute to solving this challenge. In this work, we demonstrate a framework in which the gated PET activity and attenuation images are jointly reconstructed and then registered to a reference frame by a joint registration approach. The method is studied and compared to common approaches by means of 2D and 3D simulations.


The present research work provides the investigation on simultaneous adsorption of multi heavy metal ions present in MSW leachate by lignite based Coal Fly ash. Municipal solid waste leachate samples were collected from the leachate pit, of Mayiladuthurai municipal solid waste open dumping site, Nagapattinam District, Tamil Nadu, India. Leachate samples were analyzed and multi heavy metal ions namely Cu, Zn, Pb, Cr and Ni were identified. The lignite based coal fly ash used for this study has been obtained from the Neyveli Lignite Corporation, a Public sector company located at a distance of 245km south of Chennai, the capital city of the state of Tamilnadu. Fly ash applicability for adsorption of such a multi heavy metal ions present in MSW leachate was studied by three Multicomponent adsorption isotherm models namely Extended Langmuir Isotherm model, Langmuir Freundlich Isotherm model and Multicomponent Isotherm model. Experimental equilibrium metal uptake data were compared with calculated values. The performance of the model were studied based on the coefficient of correlation.


Abstract Synthetic applications of ethyl 3-bromodifluoromethyl-3-benzyloxy-acrylate as a versatile and multifunctionalized gem -difluorination building block to introduce difluoromethene subunit into some new hydroxy esters have been investigated. It was found that its zinc mediated reaction with a variety of aldehyde in DMF gave the Reformatsky reaction mode product, β-hydroxy ester, in good yield, while its tetrakis(dimethylamino)ethylene (TDAE) promoted reaction with a limited scope of aldehyde produced Barbier reaction mode product, δ-hydroxy ester, in moderate yield. The reaction of its zinc reagent with styrene oxide resulted in rearrangement of the epoxide to 2-phenyl-acetaldehyde, and then the zinc reagent condensed with this aldehyde to provide the Reformastsy reaction type product, β-hydroxy ester, in low yield.

Focusing of 0-to 1.5-THz transverse-acoustic phonons in GaAs is studied on the basis of an ex tended rigid-ion model, which reproduces very accurately the observed dispersion curves of acoustic phonons. The shifts of phonon caustics due to lattice dispersion become conspicuous at frequencies above 1 THz. Calculated focusing patterns of ballistic phonons are found to be in good agreement with the characteristic features of phonon images obtained recently by Wolfe and Northrop. We also compare the dispersive shifts of caustics in GaAs with those in Ge and discuss its implication to the phonon-focusing experiments with large-wave-vector phonons.


The Newham Children's Services Occupational Therapy Department faced a number of major challenges, including an insufficient capacity to meet the growing demand for services, insufficient funding, an inability to fill posts consistently and an extremely long waiting list. It used business process redesign (BPR) techniques to address these problems. The redesign process involved a systematic and thorough approach to problem solving and the implementation of the solutions. Within 3 years, the team had decreased significantly both the rate of formal complaints and the length of the waiting list. It had also increased staff retention and morale. The team's success demonstrates that BPR can be a useful tool in improving the efficiency and effectiveness of occupational therapy services and stakeholder satisfaction.


Dynamic legged locomotion entails navigating unstructured terrain at high speed. The discontinuous foot-fall patterns and flight phases, which are pivotal for its unrivaled mobility, introduce large impulses and extended free-falls that serve to destabilize motion estimation. In a nod to biological systems, visual information, in the form of optical flow, is used with a hybrid estimator tuned to the principal phases of legged locomotion. This takes advantage of the ballistic nature of the flight phases to vary optical flow calculation methods and estimator parameters. Experimentation on a single-leg shows a reduction in inertial drift. In tests with 6g impulses, pose was recovered within 5deg rms with angular rate errors limited to 10 deg/sec at frequencies up to 250 Hz. This compares well with angular rate recovery by vision only and traditional inertial techniques.

Power Africa is an initiative launched by US President Barack Obama in July 2013 to bring power to unelectrified communities in Sub-Saharan Africa. We developed a power system model of the rural village of Katumbi, Tanzania. Utilizing RTDS, a cutting edge technology for power system simulation, we built and verified a microgrid based on real data from Katumbi. The microgrid is powered by distributed energy resources such as a solar panel farm, wind turbines, and thermal generation. The control capabilities of the microgrid are reactive power support, fault voltage ride through, load shedding, and voltage unbalance. Simulation shows the microgrid is able to withstand a variety of disturbances, and is built for a population and geographic expansion of Katumbi due to the numerous benefits that electrification provides rural communities. The microgrid allows for the addition of community resources such as a hospital, freezers to store the catch of fishermen, a school, and a tower for wireless communication within the community. These will bring economic, social, and health benefits to this rural, impoverished community.


Infrared imaging guidance is a research hotspot in accurate terminal guidance field now. An idea on automatic extraction of region (ROI) of interest in infrared serial images is proposed in order to treat intelligently infrared serial images which are captured. The target detection algorithm of target is researched and the applying scene of the target detection algorithm is confirmed based on analysis for the features of infrared serial images. According to differences of detection algorithm for infrared serial images between static and dynamic scenes, the corresponding detection and extraction algorithm of ROI is discussed respectively. The algorithms are all simulated in real scene. A new stepwise approaching and recurring threshold search algorithm based on two-dimensional maximum entropy principle was proposed by studying recurring formulation optimized of two-dimensional maximum entropy in order to realize to detect target and extract ROI of serial images under complex background. The algorithm above realizes automatic extraction of ROI in Infrared serial images. The results improve the efficiency of accurate terminal guidance and they have good application value by practicing.


This paper deals with the amplified spontaneous emission(ASE) of thin films of a red dye(compound),2-(1,1-dimethylethyl)-6(2-(2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1-1H,5H-benzo(ij)(uinolizin)-9-yl)ethenyl)-4H-pyran-4-ylidene) propanedinitrile(DCJTB),in various polymer matrices of poly(methylmethacrylate),poly(styrene) and poly(N-vinyl carbazole),which were pumped at 355 nm with THG Nd ∶ YAG laser.The DCJTB ∶ poly(N-vinyl carbazole) film shows an effective and large ASE intensity,the(lowest) threshold and the maximum optical gain coefficient.Our results indicate that DCJTB ∶ poly(N-vinyl(carbazole)) could be a promising candidate for the gain medium of optically pumped polymer lasers.


With the recent paradigm shift from cytotoxic drugs to new generation of target therapy and immuno-oncology therapy during oncology drug developments, patients with various cancer (sub)types may be eligible to participate in a basket trial if they have the same molecular target. Bayesian hierarchical modeling (BHM) are widely used in basket trial data analysis, where they adaptively borrow information among different cohorts (subtypes) rather than fully pool the data together or doing stratified analysis based on each cohort. Those approaches, however, may have the risk of over shrinkage estimation because of the invalidated exchangeable assumption. We propose a two-step procedure to find the balance between pooled and stratified analysis. In the first step, we treat it as a clustering problem by grouping cohorts into clusters that share the similar treatment effect. In the second step, we use shrinkage estimator from BHM to estimate treatment effects for cohorts within each cluster under exchangeable assumption. For clustering part, we adapt the mixture of finite mixtures (MFM) approach to have consistent estimate of the number of clusters. We investigate the performance of our proposed method in simulation studies and apply this method to Vemurafenib basket trial data analysis.


Since the large demand has been placed on building material industry especially in the last decade owing to the increasing population which causes a chronic shortage of building materials, the civil engineers have been challenged to convert waste to useful building and construction material. Recycling of such waste as raw material alternatives may contribute in the exhaustion of the natural resources; the conservation of not renewable resources; improvement of the population health and security preoccupation with environmental matters and reduction in waste disposal costs. In the review of utilization of those waste, this paper reviewed recycling various waste material in bricks production. The effects of those wastes on the bricks properties as physical, mechanical properties will be reviewed and recommendations for future research as out comings of this review will be given. This reviewed approach on bricks making from waste is useful to provide potential and sustainable solution.


A spectrophotometirc study of the vapor species present at equilibrium in high temperature, metal-metal salt systems was performed in an effort to characterize the nature of the species present and evaluate the thermodynamic functions which describe their interaction. A Cary 14 recording spectrophotometer was modified to permit the investigation of the high temperature systems. In addition to the characteristic BICL$sub 3$ and BiCl bands, the absorption spectra of Bi-BiCl$sub 3$-AlCl$sub 3$ systems exhibited a band at 723 m /lower mu/ which corresponded to BiAlCl$sub 4$. A quantitive study of the system over the temperature range 650 to 900 degrees yielded a value of -28.1 +- 0.5 Kcal for /cap delta/H$sup o$$sub 1050$ for the reaction BiCl(g) + AlCl $sub 3$ (g) = BiAlCL$sub 4$(g). Using this enthalpy and an estimated entropy, a value of 16.8 Kcal was computed for /cap delta/F$sup o$$sub 1050%. Systematic deviations in the data at low temperature (<650 degrees) were ascribed to the formation of compounds in the melt and the resultant decrease in the activities of the components in the system. A series of previously unreported bands in the near infra-red spectrum (~ 1500 m/lower mu/) was assigned to BCl(g) although the exact nature of the transitions was unknown. Two broad bands (510 and 670 m/lower mu/) observed in the spectra of the Te-TeCl4 system were found to correspond to TeCl2(g). Quantitative studies of the data in the temperature range 275 to 350 $sup o$ yielded a value of 23.5 +- 2 Kcal for /cap delta/H $sup degree$$sub585$ for the reaction Te(s) + TeCl $sub 4$ (g) = 2 TeCl$sub 2$ (g). The value 38.7 +- 4 eu computed for /cap delta/S$sup o$ using this entalpy and K$sub p585$ (0.49 atm) corresponds quite well with a value of 44.7 eu estimated from data available in the literature. This equilibrium accounts for the low temperature transport of tellurium which has been observed in the Te-TeCl$sub 4$ systems. As a result of the extensive compound formation in Te-TeCl$sub 4$-AlCl$sub 3$ melts, quantitative studies of the vapor species above such systems are not possible. (author)


SUMMARY

The effect of coconut water (CW) and of 2,4-dichlorophenoxyacetic acid (2,4-D), applied singly or in combination, to clonal material of excised roots of tomato cv. 'Moneydor' was investigated. Distinct stimulatory effects on the growth of roots were obtained in both cases. CW showed its highest growth action when applied at low concentrations (0.025% and 0.050% v/v) to roots incubated in darkness. Certain combinations of CW and 2,4-D gave a strikingly high growth rate which exceeded that of the control with or without CW. Acombination of 2 × 10−4 µg. ml of 2,4-D with 0.050 % (v/v) of CW gave maximum growth stimulation without toxicity to the root tissue.


The influence of heterovalent doping of LaF 3 with SrF 2 on the electrical behavior of a silicon-based chemical sensor and ion conductivity of the doped LaF 3 layer were investigated. An improved quality of field effect devices was achieved using a La (0.964) Sr (0.036) F (2.96) layer instead of the insulator. Capacitance voltage curves of metal/ionic conductor/ semiconductor (MICS) devices are much steeper than for conventional metal/insulator/ semiconductor (MIS) devices. It was proven that interface, not insulator-bulk, capacitances dominate the behavior of the field effect device. The results obtained can be applied to field effect devices other than chemical sensors.


Publishing business in Ukraine has its own characteristics and conditions of operation. The variability of conditions is influenced by a number of external and internal factors that encourage it to "behave" in certain periods of time to respond to them. The proof of this is significant changes in the volume of publishing production in dynamic for several years. Ignoring the factors influencing the publishing business can lead to considerable risks in its proceeding. Consequently, the purpose of the study is the identification and analysis of factors affecting the domestic publishing business. The results are as follows. Firstly, the features of the proceeding of modern domestic publishing business in terms of systemic economic crisis and high competition are observed. Secondly, the basic indicators of its development for five years are analyzed and definite conclusions about the impact of external and internal factors on it are made. The impact of external factors on the publishing business with the use of PEST-analysis is investigated. Then, the internal factors' impact on publishing business condition and development are systematized. The need to consider the studied factors in an integrated approach is noted. Finally, it is emphasized that consideration of the factors influencing the publishing business is one of the important conditions for reducing its risks. The content difference of factors influencing the publishing business is specified, depending on the nature of social and economic processes in society. The conclusions are as follows. The effects of the systemic crisis influences publishing business in Ukraine. In order to reduce its negative effects, we must consider internal and external factors of influence on it. The analysis of the domestic publishing business points to its instability. All the factors such as political, economic, institutional, social, technical, technological, etc. that influenced the publishing business should be considered for their content but necessarily in complex. Each publishing structure should define its inherent factors of influence the publishing business to effectively take them into account in its proceeding. Thus, the perspective of study of this problem, in our opinion, is the profound analysis of each of the aforementioned types of factors by joint efforts of researchers and practicians.


Acute myocardial infarction is necrosis of any myocardial mass due to ischemia. COVID-19 can be complicated by thrombosis and myocardial damage, which can lead to the deployment of a clinical picture similar to acute myocardial infarction. The material of this article is presented on the example of a clinical case. A woman aged 37 was diagnosed with an acute myocardial infarction, which later turned out to be a manifestation of a complicated course of coronavirus COVID-19 infection. This case drew attention to the absence of a clinical picture specific to this infection in the form of a damage to the respiratory system or intoxication. The case is also distinguished by the presence of a single uncharacteristic clinical manifestation of COVID-19 in the form of a cardiovascular event with elevations of the ST segment on the cardiogram and other objective data and additional research methods characteristic of acute myocardial infarction. The work also analyzed the pathogenetic mechanisms of acute myocardial infarction and cardiovascular complications of COVID-19, examined the general links of pathogenesis of these two pathological units and analyzed the causes of difficulties in their differential diagnosis. In this regard, there are unquestionably complications of differential diagnosis and the prescription of timely correct therapy. A deeper understanding of these data may improve the algorithms for diagnosing acute myocardial infarction and cardiovascular complications of COVID-19.


The treatment of Benign Prostatic Hyperplasia using the Nd:YAG laser is developing rapidly since the clinical introduction three years ago. In most cases a right angled fiber is used to deliver the laser light laterally towards the abundant prostatic tissue. The characteristics of these fibers differ, with regard to the angle at which the beam exits the fiber and the beam profile, resulting in a specific power density distribution on the tissue. During clinical use the characteristics of a fiber may change due to deterioration of the fiber tip. In this study the behavior of the various devices was monitored before and during clinical use with a special design power meter (Aquarius). The Aquarius measures the status of a right angled fiber in about fifteen seconds under clinical conditions, i.e., under water and at high input powers (40 - 80 Watt). In contrast with integrating sphere power meters specifically the primary beam is measured. The degree of deterioration of various fibers was quantified optically and thermally during clinical use. Devices using a metal mirror transmitted slightly less power than internal refraction based devices (80 versus 90 percent). The transmission of the various devices was not linear with the input power; at higher input powers (> 30 Watts) vapor bubbles, that developed at the tip of the device, decreased the transmission. During clinical use there was a large variation in decrease of transmission with regard to the total amount of energy transmitted through the fiber. However, at the end of a procedure the transmission had dropped to under 50%. The Aquarius is a powerful tool for evaluation and comparison of different laser prostatectomy devices both for clinical and experimental studies.


It is a requirement of "air defense forces informationization construction" to quantitatively evaluate weapon and equipment from microscopically angle. Linking the practical deployment of the air defense forces with the requirement of informationization of the air-defense weapons, this paper presents the evaluation index set, and builds an evaluation model with power exponent and linear weight. It takes an anti-raid brigade as an example to practice the evaluation. The result of it shows that it reflects reality of the weapon informationization of the brigade, and proves its correction and feasibility.


We present and discuss a wide-range hydrogen equation of state model based on a consistent set of ab initio simulations including quantum protons and electrons. Both the process of constructing this model and its predictions are discussed in detail. The cornerstones of this work are the specification of simple physically motivated free energy models, a general multiparameter/multiderivative fitting method, and the use of the most accurate simulation methods to date. The resulting equation of state aims for a global range of validity ($T = 1-10^9 K$ and $V_m = 10^{-9}-1 m^3/mol$), as the models are specifically constructed to reproduce exact thermodynamic and mechanical limits. Our model is for the most part analytic or semianalytic and is thermodynamically consistent by construction; the problem of interpolating between distinctly different models -often a cause for thermodynamic inconsistencies and spurious discontinuities- is avoided entirely.


An investigation of the conformational properties in the solid state and in solution of 2- and 3-p-anisoyl derivatives of thiophene and of benzo[b]thiophene, compounds (1b) and (2b), and (3) and (4) respectively, is reported. X-Ray analysis of the compounds gave the following crystal data: (1b) space group Pbca, a= 18.479(2), b= 11.450(1), c= 9.874(1)A, Z= 8, R= 0.0438 for 1 611 observed reflections; (2b) space group Pbca, a= 46.245(25), b= 7.393(4), c= 6.195(3)A, Z= 8, R= 0.0435 for 1 153 observed reflections; (3) space group P212121, a= 14.039(2), b= 12.469(2), c= 7.457(1)A, Z= 4, R= 0.0697 for 1 871 observed reflections; (4) space group P21/a, a= 11.138(5), b= 14.698(6), c= 7.764(5)A, Z= 4, R= 0.0556 for 1 983 observed reflections. In each of the molecules the rings are twisted with respect to the carbonyl plane, the heterocyclic ring is less twisted than the phenyl ring, and this deviation from planarity is particularly evident in the 2-substituted derivatives (1b) and (3). The orientation of the carbonyl group is of the S,O-cis and S,O-trans type in the 2-substituted and 3-substituted compounds; the former derivatives show the presence of attractive interactions between the sulphur and oxygen atoms. The conformational properties in chloroform were studied with the n.m.r. lanthanide-induced shifts (LIS) method (1H and 13C nuclei were employed). The preferred conformation (ca. 70%) found for derivatives (1b) and (3) is of the S,O-cis type, with the thiophene ring nearly coplanar with the carbonyl plane and the phenyl ring twisted. For derivative (2b) the preferred conformation in the equilibrium mixture is the S,O-trans type, yet in derivative (4) this conformation is almost exclusive. The heterocyclic and aryl rings show nearly the same degree of twist relative to the carbonyl plane. The conformational situation of derivatives (1)–(4) is compared with that of the corresponding furan and benzo[b]furan derivatives, and close conformational behaviour is found for the 3-substituted compounds. MO Ab-initio calculations in the minimal STO-3G basis set were also performed on the 2- and 3-benzoyl derivatives of thiophene, chosen as model compounds of those under investigation, and the conformations of minimum energy were located in the potential energy surface. For the 2-substituted compound (1a) the conformation of S,O-cis type was found to be the more stable conformer and a lower degree of twisting was found for the heterocycle than for the phenyl ring, in agreement with the experimental findings relative to compound (1b). For the 3-substituted derivative (2a) the results of calculations showed that the two conformers of the S,O-cis and S,O-trans type differ only slightly in energy content, the former being predicted to be more stable, in contrast with the experimental behaviour found for derivative (2b).


S-(tert-Butyl)trifluorothioacetate, CF3C(O)SC(CH3)3, was prepared by condensation of CF3C(O)Cl and (CH3)3CSH under vacuum conditions. The compound was isolated and properly characterized by using vibrational (infrared and Raman), UV-Vis and multinuclear NMR spectroscopy techniques and by mass spectrometry. The conformational preference and its crystal structure have been determined by means of FTIR spectroscopy (gas phase and Ar-matrix) and by X-ray diffraction. A charge density determination of X-ray diffraction (XRD) data of single crystals formed by in situ crystallization reveals the presence of solely a synperiplanar conformation (syn form orientation of the CO double bond with respect to the S–C single bond) belonging to the Cs point group of symmetry. Intermolecular CO⋯CO and CO⋯H–C interactions were detected in the crystal. Quantum-chemical calculations at the B3LYP/cc-pVTZ level of approximation reproduce the conformational preference and the experimental geometrical parameters fairly well. Vibrational information was obtained from Ar-matrix isolation FTIR and liquid Raman spectroscopy. Additionally, CF3C(O)SC(CH3)3 isolated in solid Ar at ca. 15 K was irradiated with UV-visible broadband light (200 ≤ λ ≤ 800 nm) and its photolysis products CF3SC(CH3)3 and CO were detected.


PURPOSE: A method for integrally managing a system failure is provided to find out a problem in early time by integrally monitoring an event for a network, a system, a database, and an application, and to facilitate the reuse by analyzing a cause of the problem. CONSTITUTION: A hardware, a software, and each application of the solutions for making respective individual solutions into a network are defined(S102). A management object of each solution is modeled through a GUI(Graphic User Interface)(S104). The system is completely constructed by setting up a relationship between the management objects constructed by the network and an event model of each solution(S108). The system is operated for the integrated system failure management and recovery(S110). In case that an additional function is added or upgraded to the system, the function is additionally installed, and the model of the management object corresponding to the system is modified or added(S112). In case that the model of the management object is modified or added, the system is tested by rebooting the system(S116), and the situation is monitored while managing/recovering the system.


The title compound 3-methyl-1-(4-methylphenyl)-4-(N-4-trifluoromethylphenyl) aminomethyl-5-(4-methoxyphenylthio)-1H-pyrazole has been synthesized via a four-step reaction and characterized by IR, H NMR, elemental analysis and X-ray crystallography. The compound crystallizes in monoclinic, space group P21/c with a = 8.7170(15), b = 18.355(3), c = 15.292(3) A, β = 103.445(3)°, V = 2379.7(7) A, Dc = 1.350 g/cm, Z = 4, μ = 0.184, F(000) = 1008, and the final R = 0.0491 and wR = 0.1339 for 4160 observed reflections (I > 2σ(I)). The results demonstrate that there is a face-to-face π-π stacking interaction between one benzene ring (C(19)~C(24)) and another (C(13)~C(18)) at a plane-plane distance of 3.3539 A. The ring normal and vector between the ring centroids form an angle of 18.2o up to the centroid-to-centroid distance of 3.5273 A. The crystal structure is stabilized by the intermolecular hydrogen bond of N(3)−H(3A)···N(2) (symmetry code: A –x+1, –y+1, –z). The preliminary biological test shows that the title compound has a moderate antifungal activity.


The management of cloud infrastructures became a lot more difficult in course of last years due to the growing demand for high quality of cloud services. The lack of the ability to adapt the existing services to the dynamically changing demand from users' side yields problems of the quality of the provided services. In the poster, we present a novel decentralized architecture and approach for automatic cloud resources management under QoS requirements and budget constraints. The proposed architecture is aimed at dynamically adapting cloud application deployment on different levels of cloud infrastructure in order to meet QoS requirements and to reduce cost of cloud services.


In order to get information about the transition mechanism, the temperature-induced transformation in the binary com¬pound NiS was investigated. Above 379 °C, a single crystal of millerite -NiS transforms to polycrystalline NiAs type -NiS with a sharp texture. Pole figures of both phases in the same orientation were measured using synchrotron radiation and an imaging plate detector. The Rietveld texture analysis showed that there are at least three components of the high-temperature -NiS phase. The main component shows the following orientation relations: [001]NiAs type  [001]millerite, [100]NiAs type  [210]millerite, [210]NiAs type  [100]millerite. The broad peaks of the recovered polycrystalline millerite occur at the same positions as the reflections of the original single crystal.

The pose measurement of cannon barrel(vertical angle and azimuth angle) is difficult but important in the precision analysis of SPAAG fire control system.To solve this problem,this paper presents a contactless measuring method based on computer vision.Before measurement,a checked planar faceplate is fixed on the cannon barrel as a marker.Firstly,the coordinates of X corner points are got using Harris cornerd detection algorithm to calibrate the camera,and the camera′s intrinsic parameters are obtained based on extended Kalman filter.Secondly,the corner points are extracted from the image of test position,and then the extrinsic parameter matrix of the corresponding position is calculatted combining with the least square algorithm.Finally,according to the motion model of cannon barrel and its position relative to the marker,the constraint equations between extrinsic parameter and vertical angle and azimuth angle are derived,and then the two angles are figured out.Experiments validate this method,and the results indicate that the measuring precision of this method is less than 0.1°.


A device for omnidirectional image viewing providing pan-and-tilt orientation, rotation, and magnification within a hemispherical field-of-view that utilizes no moving parts. The imaging device is based on the effect that the image from a fisheye lens (1), which produces a circular image of an entire hemispherical field-of-view, which can be mathematically corrected using high speed electronic circuitry (5, 6, 7, 12 and 13). More specifically, an incoming fisheye image from any image acquisition source (2) is captured in memory (4) of the device, a transformation is performed for the viewing region of interest and viewing direction, and a corrected image is output as a video image signal for viewing, recording, or analysis. As a result, this device can be accomplish the functions of pan, tilt, rotation, and zoom throughout a hemispherical field-of-view without the need for any mechanical mechanisms. The preferred embodiment of the image transformation device can provide corrected images at real-time rates, compatible with standard video equipment. The device can be used for any application where a conventional pan-and-tilt or orientation mechanism might be considered including inspection, monitoring, surveillance, and target acquisition.


Heuristics are a much researched, scientifically studied way to solve usability issues in user interface. However, the way of conducting usability evaluation is based on abstract models. As the heuristics as guidelines are abstract and their interpretation depends on the researcher, the gap between scientifically created heuristics and the practitioners' methods of developing games has grown. This study introduces the Explicit Heuristics Design-model (EHD). It has been developed by using design science research methodology. This model can be implemented by using heuristic evaluation and expert evaluation methods. The EHD-model enables the extraction of explicit heuristics data from the games. The hypothesis proposed a connection between the heuristics and the revenue. The final evaluation phase of the EHD-model revealed that a correlation between the heuristics and the revenue generated by Android mobile fighting games exist. The EHD-model was also able to point out the most important heuristics affecting the generated revenue. This study reduces the gap between the scientific community and practitioners. It offers the scientific community a new view and results concerning heuristics and the practitioners a tool to enhance the profitability of a game.


A multi-domain Galerkin method is presented for the Burgers equation, whose solutions behave differently at positive infinity and negative infinity. The original problem is transformed into a problem with general variable coefficients and homogeneous boundary conditions at infinities by using the auxiliary function, which is capable of being reformulated as a suitable variational formulation that is the most convenient for analysing numerical error. As an application, the composite spectral scheme with numerical integration is provided for the underlying problem on the whole line, which is easy to deal with problems concerning general variable coefficients. Some composite generalized Laguerre–Legendre interpolations on the whole line are established. The convergence and stability of the proposed algorithm are proved. Numerical results show the efficiency of this approach and agree well with the theoretical analysis.


It is a given that, for whatever reason, the Children of Paul's broke in 1608. This article, to the contrary, foregrounds the argument that, far from breaking, the highly successful Children of Paul's remade themselves into the highly successful adult acting company the Duke of York's Men for the simple reason that their players had grown too old to be any longer acceptable to audiences as 'children'. The Children of Paul's is last seen in February 1608; the Duke of York's Men first appear in October 1608 under the royal patronage of Prince Charles, Duke of York. The new adult company featured the extraordinary Joseph Taylor – later to succeed Richard Burbage as the greatest player in England – and the multi-talented William Rowley, who acted as manager, playwright and comedian for the ensemble. Evidence is presented that Taylor, Rowley and others of the Duke of York's Men were previously members of the Children of Paul's.

This study investigated the annual and seasonal rainfall variability at five selected stations of Amhara Regional State, by using the innovative trend analysis method (ITAM), Mann-Kendall (MK) and Sen's slope estimator test. The result showed that the trend of annual rainfall was increasing in Gondar (Z = 1.69), Motta (Z = 0.93), and Bahir Dar (Z = 0.07) stations. However, the trends in Dangla (Z = −0.37) and Adet (Z = −0.32) stations showed a decreasing trend. As far as monthly and seasonal variability of rainfall are concerned, all the stations exhibited sensitivity of change. The trend of rainfall in May, June, July, August, and September was increasing. However, the trend on the rest of other months showed a decreasing trend. The increase in rainfall during Kiremt season, along with the decrease in number of rainy days, leads to an increase of extreme rainfall events over the region during 1980–2016. The consistency in rainfall trends over the study region confirms the robustness of the change in trends. Innovative trend analysis method is very crucial method for detecting the trends in rainfall time series data due to its potential to present the results in graphical format as well. The findings of this paper could help researchers to understand the annual and seasonal variability of rainfall over the study region and become a foundation for further studies.


On the credit side can be put increases in the Indian lion and the great Indian rhinoceros. In 1950 the lion population of the Gir Forest was carefully assessed at 250 (see Oryx, vol. I, No. 2, pp. 99–101). In 1955 a similar census gave 290, an increase of 40 in four years, though the proportion of cubs to adults had decreased.


Abstract Both fire and water protection are crucial for the safety and usability of paper-based products applied as building components. The presented study investigates the possibility of combining environmentally-friendly fire retardants with oil- and wax-based waterproofing coatings on paperboard for architectural applications. The proposed impregnation technique can be used as protection for paper-based temporary and emergency structures, or as part of the protective system for building envelopes of permanent structures. The fire retardants selected for the tests were diammonium phosphate and a mixture of borax and boric acid in a 1:1 ratio. Single-flame ignitability tests were performed on the impregnated specimens to assess the fire performance of specimens with fire impregnation, waterproofing impregnation and both. A Life Cycle Assessment analysis was performed for fire-retardant paperboard. The study has shown that the application of layered fire and waterproofing treatments on paperboard components is possible and leads to a significant reduction in flammability compared to untreated and only waterproofed specimens.


Accessibility, defined as the potential of opportunities for interaction, is a key concept in urban planning. Traditionally, the measurement of accessibility relied on methods that used simplified information on transit networks. Recent developments of public transport structured data through Global Transit Feed Specification (GTFS) fostered the creation and standardization of many tools to estimate travel times between origin-destination pairs, feeding the calculation of accessibility indicators. However, researchers are beginning to better understand to what extent differences between scheduled GTFS data and real services can affect accessibility estimates. The aim ofthis dissertation is to analyze the variability of accessibility indicators by public transport to work and education opportunities using location data and smart card data in a large transportation system. This variability of accessibility is investigated through three main hypotheses: 1) there is a difference between measuring it with Scheduled GTFS versus Empiric GTFS; 2) there is a difference between measuring it with Empiric GTFS based on median observed travel times versus based on a dispersion measure of observed travel times on the network; 3) there is a difference between measuring it to different departure times within peak hour. Initially, the proposed method consolidates and integrates one month of big data database, preparing them to the GTFS reconstruction approach. Using geoprocessing techniques, it starts by transforming raw GPS points to a structured transit timetable. The timetable times are then aggregated by 15 minutes intervals and segments between stops, determining the median and 85 percentile travel time to produce two empiric GTFS files. These files, alongside the Scheduled GTFS, are then used to estimate travel time between origin-destination pairs, making possible to estimate accessibility indicators based on scheduled and real-time data at different departure times within peak hour. Smart card data is used to estimate time thresholds to calculate cumulative indicators. The results corroborate the three hypotheses of variability on the spatial distribution of accessibility indicator by work and education activities. This variability is higher for access to jobs opportunities given its strong concentration on the central area of Fortaleza. These results suggest that decision makers take this variability into consideration when they assess the accessibility impacts of future interventions.


This article is the result of a research which aims to describe the implementation of Smart city in Bandung in terms of technology, human and institutional aspects. The research was conducted with a descriptive qualitative approach. Data collection was carried out by semi-structured interviews with 37 informants, observation and documentation. The research findings show that the socialization related to the smart city program, especially in socializing service applications to the public, is still not widespread so that it has an impact on the lack of citizen knowledge regarding the smart city program and the Bandung City Government has ratified the Bandung Smart city master plan standard operating procedures related to information systems in order to realize smart city in the city of Bandung. It is recommended to increase continuous socialization, educate the public regarding online applications in collaboration with campuses, as well as implement the Bandung Smart City master plan and conduct evaluations at each stage that has been implemented.

This report describes the efficacy of tolvaptan for the treatment of protein-losing enteropathy (PLE) that developed in two patients who underwent the Fontan operation. The first patient was an 8-year-old boy with asplenia,dextrocardia,common atrioventricular canal (CAVC),univentricular heart (UVH),pulmonary atresia and total anomalous pulmonary venous connection. Although intravenous heparin,oral corticosteroids and intravenous albumin were administered,serum albumin and total protein levels were only approximately 2 g/dL and 3 g/dL,respectively. Subsequent administration of tolvaptan resulted in normalization of serum albumin and total protein levels and a decrease in PLE-related diarrhea. The second patient was a 19-year-old man with polysplenia,UVH,CAVC,double-outlet right ventricle,pulmonary atresia and interrupted inferior vena cava (azygos connection). Tolvaptan administration in this patient resulted in an increase in serum albumin and total protein levels and a decrease in ascites. These observations suggest that tolvaptan may be an effective treatment option for PLE in the patients who have undergone the Fontan operation.

Urban energy mapping plays a crucial role in benchmarking the energy performance of buildings for many stakeholders. This study examined a set of buildings in the city of Borlange, Sweden, owned by the municipality. The aim was to present a digital spatial map of both electricity use and district heating demand in the spatial–temporal dimension. A toolkit for top-down data processing and analysis was considered based on the energy performance database of municipality-owned buildings. The data were initially cleaned, transformed and geocoded using custom scripts and an application program interface (API) for OpenStreetMap and Google Maps. The dataset consisted of 228 and 105 geocoded addresses for, respectively, electricity and district heating monthly consumption for the year 2018. A number of extra parameters were manually incorporated to this data, i.e., the total floor area, the building year of construction and occupancy ratio. The electricity use and heating demand in the building samples were about 24.47 kWh/m2 and 268.78 kWh/m2, respectively, for which great potential for saving heating energy was observed. Compared to the electricity use, the district heating showed a more homogenous pattern following the changes of the seasons. The digital mapping revealed a spatial representation of identifiable hotspots for electricity uses in high-occupancy/density areas and for district heating needs in districts with buildings mostly constructed before 1980. These results provide a comprehensive means of understanding the existing energy distributions for stakeholders and energy advisors. They also facilitate strategy geared towards future energy planning in the city, such as energy benchmarking policies.

We have used nuclear reaction analysis to measure diffusion coefficients D in couples consisting of hydrogenated polybutadienes of structure (C 2 H 3 (C 2 H 5 )) x (C 4 H 8 ) 1-x and their partly deuterated counterparts. The 1,2- and 1,4-olefinic isomers are randomly distributed along the chains and the mean vinyl fraction x varies between 0.38 and 0.94. We find that the effective monomeric mobility D 0 [defined by D = D 0 (N e /N 2 ) for each copolymer, where N is the backbone length and N e the entanglement spacing] decreases monotonically with increasing vinyl content x. Over the range of microstructures and temperatures T (-14-40°C) investigated we find log(D 0 /T) varies smoothly with (T - T g ), where T 5 is the glass transition temperature of the respective melts. An analysis of our data in terms of a simple activated rate process model suggests that D 0 is controlled by thermally activated hopping of segments whose effective volume is close to that of the respective statistical segment lengths of the copolymeric chains.


As this Harm Reduction supplement of N&TR was being prepared for press, juries in Oregon and California gave implicit recognition of the complexities of harm reduction: A product advertised to reduce harm may in fact increase smoking-related health risks because it falsely assures smokers they need not quit. In a first-of-its-kind decision, an Oregon jury ordered cigarette manufacturer Philip Morris to pay $150 million in punitive damages and $168,000 in compensatory damages to the estate of a woman who died of lung cancer in 1999 after smoking low tar cigarettes. She had switched to the low tar brand believing it would be better for her health. The lawsuit contended that low tar cigarettes are as dangerous as regular ones, and the jury agreed, ruling that Philip Morris had falsely represented low tar cigarettes as less harmful.


Use of the Casagrande-style plasticity chart to classify fine-grained soils using Atterberg ' s liquid and plastic limits is ubiquitous in geotechnical engineering. This classification is dependent on the thread-rolling and Casagrande-cup tests, which are both more operator dependent than the fall-cone liquid limit test. This paper shows that the slope of the data acquired during the fall-cone liquid limit test (the fall-cone flow index) can be used to redraw the plasticity chart, thus allowing classification of fine-grained soils to be achieved solely from fall-cone liquid limit data.


It is well appreciated that demographic trends threaten the integrity of continental European systems of social security. For France, these trends imply a long term funding crisis as well as a crisis of confidence in national economic and social institutions. The funding of social security is a recurrent largely unresolved political issue; proposals for comprehensive reform are heavily contested and often stymied by organised interests willing to go to the streets. At the same time, incremental changes introduced by governments from the left and right will likely discount the expected value of future retirement benefits. In this paper, I begin by sketching the logic of pay-as-yougo social security, identifying the basic economic and social institutions that together provide universal coverage. One goal of the paper is to articulate the economic and philosophical roots of social solidarity and the importance of the state as the custodian of the social contract between generations. In doing so, I sketch-out the French ideal: a coherent social security system based upon self-reinforcing mutual obligations and institutions. But I also argue that its current problems could have been anticipated in 1955 and have been the subject of various government reports over the last 25-30 years. A second goal of the paper is to show how and why the French social-security system became unsustainable. The French state used the retirement system as a form of labour market policy, thereby undercutting both its financial integrity and its political legitimacy. The third goal of the paper is to demonstrate the significance of younger individuals' possible defection from social solidarity. Basically, I dispute the argument that national systems of governance necessarily persist; internal inconsistencies and defection when combined with external opportunities in very different systems of governance may overturn the past. By making this argument, I do not mean to suggest that the AngloAmerican model is obviously superior to social security systems based on social solidarity. Quite the contrary. Rather, my point is entirely argumentative: solemn incantations that defend the past, whatever their best intentions, may simply reinforce the nature and significance of the pending crisis.


Abstract I investigate the determinants of interstate political alignment, examining why states take part in ongoing conflicts and which side they take in them. The puzzle I seek to address is why some states are much more likely to gain support than others, and whether the likelihood of such support varies on the basis of the issue under dispute and the characteristics of the state itself. I emphasize the interests of rulers, particularly their need to obtain support on issues of high salience to them. The desire for future reciprocity lies at the heart of these alignment decisions. First, leaders consistently reciprocate positive and negative alignments. Second, rulers avoid positively aligning with leaders of unstable or politically unrepresentative states, as the latter are less likely to be in a position to return the favor. In order to test this alignment explanation, I compile a dataset of interventions into existing wars, MIDs, and sanctions regimes, covering the 1816–1999 time period. The results show that not all types of states are likely to enter an ongoing conflict. When those states do join a dispute, they do so on the side of those who helped them in the past.


In this project, we develop a website that is kind a news blog website related to any kind of news like international, sports, technology etc. It is an effort to give people some idea about something that they are going to consume. We named this website TINY NEWS. We have used HTML5, CSS3, JavaScript and jQuery, Bootstrap for front end and PHP Codeigniter MVC framework for server end and MySQL for the database. And also we are hoping to make the site smarter in future.


We analyze the role of slab pull acting on the Pacific plate during its early Tertiary change in motion. Slab pull forces are estimated by integrating the negative buoyancy of a 700 km long slab along a revised subduction boundary model adopting the Müller et al. (2008) seafloor age reconstructions. Our results indicate that torques predicted from a simple slab pull model match the Pacific plate Euler vectors during the Tertiary fairly well. The change of the Pacific motion at ∼50–40 Ma appears to be driven by the onset of the Izu‐Bonin‐Mariana system and, soon afterwards, by the Tonga‐Kermadec subduction zones.


Over the past eight years there has been exciting progress in the application of genetic engineering to the development of crops resistant to herbicides. Two broad scientific strategies have been pursued; herbicide detoxification and alteration of the target site of herbicide action. Notwithstanding the obvious commercial and regulatory issues associated with the introduction of this technology, the main benefits which may accrue are likely to arise from more effective weed control, reduced costs of weed control, overall reduction in herbicide usage and a reduction, or even elimination, of cultivation, thereby providing a long -term soil conservation benefit.


A synthesis of cryptophycin 52 (2) is reported using a Sharpless asymmetric dihydroxylation (AD) strategy to install the epoxide moiety. The high stereoselectivity of the AD reaction that allows for an efficient means of preparing the epoxide is in contrast to the standard direct epoxidation of cryptophycin substrates, which proceeds with poor diastereoselectivity. Methodology for conversion of the diol AD product to the requisite epoxide is disclosed. The transformation has been optimized to proceed in high yield in the presence of base sensitive functionality.


Spintronics devices exploiting the spin of the electron [1-10] are prepared to revolutionise the electronics industry. The significance of this new generation device is faster memory and lower power consumption at low electron density. The late 20th century has been considered as an era of microelectronics. However, the avalanche growth of microelectronics is a major threat to Moore's law and spintronics may be a solution for it. From the first transistor to the signally powerful microprocessor in our recent computers, most electronic devices have employed circuits that express data as binary digits, or bits (1 and 0) represented by the existence or absence of electric charge. Unlike microelectronics, spintronics exploits spin (spin up ↑ and spin down ↓) of the electron to carry information between devices. The discovery of Giant Magnetoresistance (GMR) by Nobel Prize winners Albert Fert and Peter Grunberg had actually led to the birth of novel field spintronics [11]. Currently, most of the existing spintronic devices [12] are based on metallic systems such as magnetic tunnel junctions (MTJs) and single electron transistor [13]. On the other hand, a wealth of intriguing spin phenomena has been observed in nanoscale materials [14]. This triggered an extensive research effort on spin transport in nanoscale MTJs and other interesting phenomena were realised. One of the most important phenomena is tunnel magnetoresistance (TMR) of the MTJs. A MTJ is composed of two ferromagnetic conducting layers separated by an ultra-thin insulating layer [15-20]. The TMR was first demonstrated by M. Julliere [21]. Yakushiji et al. [22] experimentally demonstrated the influence of spin conduction on TMR. The enhancement and oscillation of TMR in ferromagnetic multiple junctions have been predicted by several authors [23-30]. However, there have been only a few experiments on spin-dependent single electron tunnelling (SET) to date [31-36] due to the difficulty in fabricating appropriate sample structures for spin-dependent SET. The desire to build spintronic devices that show larger spin dependent phenomena has led many researchers to combine single electron tunneling (SET) and spin dependent electron tunneling (SDT). The charge quantization in low capacitance magnetic tunnel junctions


The northwestern Pacific Ocean and East China Sea (ECS) are frequently affected by typhoons during the summer period. To identify changes in production and consumption rates of phytoplankton (<20 and 20~200 µm) affected by Typhoon Maria (9-10 July 2018), 2 sampling periods were compared: a pre-typhoon cruise (4-9 July 2018) and a post-typhoon cruise (13-17 July 2018). Results showed that <20 and 20~200 µm phytoplankton production was 14- and 1.8-fold higher, respectively, in the post-typhoon period compared to the pre-typhoon. Accompanying this post-typhoon shift from pico- and nanophytoplankton to microphytoplankton, the consumption rate of microzooplankton on <20 µm phytoplankton was 11.6 mgC m-3 d-1 in the pre-typhoon period, and increased to 203.3 mgC m-3 d-1 after the typhoon. Furthermore, the ingestion fluxes were 4.9 and 8.0 mgC m-3 d-1 through mesozooplankton grazing on microzooplankton (ciliates and dinoflagellates) pre- and post-typhoon, respectively. Our findings show that organisms from the microbial food web (i.e. ciliates and dinoflagellates) may control the phytoplankton assemblage during the post-typhoon period of increased productivity, and thus represent an important trophic link between the classical and microbial food webs in the southern ECS.


Diastereoisomeric 1,2-orthoacetates of D-mannose are formed under conditions of the Konigs–Knorr synthesis. This is shown by the isolation of two crystalline isomers of β-D-mannose 1,2-(benzyl orthoacetate), and also by examination of the nuclear magnetic resonance (n.m.r.) spectra of several D-mannose orthoacetates. The diastereoisomers show notable differences in respective chemical shifts for the C-methyl and other protons and these variations, together with isomer-ratio data, suggest that the major isomer of a given pair possesses the configuration in which the C-methyl group is endo- and the OR group is exo-. On acid hydrolysis the orthoacetates yield mainly 2-O-acetyl-D-mannose, the structure of which is confirmed by n.m.r. spectral evidence.


The kinetics of slurry phase air oxidation of benzyl alcohol to benzaldehyde over zirconium vanadate
catalyst is reported in this study. Initial rates for the formation of product were determined by varying
the partial pressures of the reactants. The data collected were found to satisfy a rate law: R =
[(k1PBk2Po)/(k1PB + k2Po)]. The study suggests that reaction follows a Mars-Van Krevelen type of
redox mechanism.


Urothelial carcinoma (UC), as one of the malignant tumors, has a high incidence, mortality, and poor survival rate. FGFR3 is one of the frequency mutation genetic events of UC. Recent studies have reported that FGFR3 mutations are associated with lower aggressiveness and better prognosis of UC, and small molecule compounds with FGFR3 mutations have been developed and treated. However, they are still limited, especially for wild‐type cells. We used Ingenuity Pathways Analysis (IPA) to analyze the significantly expression of 351 genes (>2‐fold change cutoff value) between FGFR3 wild‐type and mutation/fusion UC cells by FGFR3 inhibitors treatment. Through the predicted canonical pathways, several metabolism‐related events have been regulated, including purine biosynthesis. Focusing on de novo purine biosynthesis, we found that several involved enzymes are upregulated in UC. In addition, we have also observed that several enzymes are inhibited by FGFR3 inhibitors in mutant cells, but not in wild type. We then hypothesized that purine biosynthetic events might confer drug resistance and promote UC tumorigenicity. To verify our observations, we determined the expression level of purine biosynthesis after FGFR3 classification. The results indicate a similar trend in clinical cohorts that overexpression of purine biosynthesis genes in FGFR3 wild‐type. Moreover, combining these genes can be used as an independent prognostic factor (HR=1.41, p=0.026). We further established the overexpression of purine biosynthesis genes in some FGFR3 mutant UC cells. We determined that purine biosynthesis genes cause FGFR3 mutations models to be more prone to mesenchymal and metastatic than controls. Our studies also observed that FGFR3 wild‐type cells promote UC cell radioresistance via purine biosynthesis and further activate the homologous recombination repair mechanism. Combining all evidence, we claim that purine biosynthesis should be focused and regarded as a novel strategy against UC.


The performance of wireless sensor networks (WSNs) can be significantly improved using adaptive cooperative diversity (SCA) technique, which is basically a cross-layer design that combines truncated ARQ at the link layer and cooperative diversity at the physical layer. LEACH is a protocol for wireless sensor networks that utilizes randomized rotation of local cluster heads to evenly distribute the energy load among the sensors in the network. This paper proposes and evaluates the performance of a selective cooperative scheme for wireless sensor networks based on scalability. The evaluation of the lifetime and packet loss rate is presented and results based on the maximum number of retransmissions, network size, packet length and initial energy by nodes are provided. Our scheme shows better performance as compared to others.

In most Western countries, the rate of unemployment has shown a rising trend over the last decades. One of the standard explanations for this is that the 'natural' rate of unemployment has risen. In order to investigate this hypothesis, a simple demand–supply model of the Finnish labour market was constructed and estimated. It is proposed that if the development of the unemployment rates can be explained is such a traditional model framework, this would suggest that changes in the 'natural' rate are not, after all, the crucial reason for the increasing unemployment rates. According to the results, the simple model was able to account for the changes in the unemployment rate very well. Furthermore, they seem to support a traditional Keynesian view of the problem, emphasizing output level and labour productivity as the main explanatory variables. Indirectly, it can be concluded that there seem to be no clear signs of a rising 'natural' rate of unemployment.


136 *Corresponding Author DOI: 10.37398/JSR.2021.650118 Abstract: Bixa orellana L., is a natural food dye yielding plant belonging to the family Bixaceae. It yields a non-toxic, edible Food dye Bixin and Nor-Bixin also popularly known as Annatto having orange-red colour and has a huge demand in the dairy industry to colour food products. In the present study, the 2 accessions of Bixa orellana L with white and rose-coloured flowers both bearing green capsules with green spines in common were identified from west and south of Bangalore city (Bangalore University and Lalbagh), Karnataka, India. These 2 accessions were analyzed for intraspecific variations with respect to the morphology, Genetic relatedness and Dye (Bixin) content. Our studies report that these 2 accessions were highly diverse and exhibited maximum variations with respect to habit and other morphological parameters. Hence these 2 accessions were subjected to SSR (Single Sequence Repeat) Marker studies. The analysis of SSR data showed high level of genetic variations. Out of 10 SSR primers, 7 primers showed polymorphism between the two accessions. A total of 43 discernible and reproducible SSR bands were generated by employing 7 selected primers. Out of them, 22 bands were polymorphic. The number of bands produced per primer ranged from 1-8. The markers described in this study could be of use in marker assisted selection, genetic improvement and breeding programmes and could help in the utilization and germplasm conservation of Rosecoloured flower and Green capsuled with green spined accession of Bixa orellana L., in systematic scientific breeding programmes which also yields maximum bixin content.


The excavations of the last eighty years, especially at Ugarit, Ebla, and Emar, have accumulated an exceptional amount of source material referring to the Syro-Canaanite god Resheph, whose history can now be followed during three thousand years. Chapter I deals with Resheph in the Ebla texts, already witnessing his assimilation to the Mesopotamian god Nergal, while Chapter II is dedicated to his consort Adamma. Western Asiatic sources of the second millennium B.C., in particular those from Mari, Ugarit, Ras Ibn Hani, and Emar, are presented in Chapter III, while Chapter IV concerns the Syro-Canaanite iconography of Resheph. His cult in Egypt during the second millennium B.C. is examined in Chapter V, while Chapters VI and VII deal with the first millennium B.C. and the later references to Resheph in midrashic literature. Aramaic, Phoenician, Hebrew, Egyptian, and Greek sources are surveyed in detail with a particular attention to biblical texts. Several indices help using the extensive onomastic and cultic data collected in the book, always with references to the original or most recent publications of the pertinent epigraphic, literary, and iconographic material.

Abstract : Organizational climate is a relatively new concept that has come upon the social research scene. It can be conceptualized as the sum of all the different perceptions individuals in an organization have with respect to the organization. This study attempted to measure and assess the prevailing organizational climate in System Program Offices (SPOs) in different phases of the weapon system acquisition process. The researchers were interested in determining if organizational climate differed in different phases of weapon system acquisition.


In the title compound, [Os(C10H14)Cl2(C18H31P)], The presence of bulky substituents imposes a structural distortion on the (2,4,6-tri-tert-butylphenyl)phosphine ligand, which is bowed.


We study the influence of quantum interference on 2D sub-half-wavelength atom localization in a four-level atom driven by three external fields with a loop structure. When the dipoles of the two transitions from two upper levels to the lower level are parallel to each other, quantum interference between the two transitions arises. The analytical expression of conditional position probability (CPP) distribution is obtained using the iterative method. We discuss the influence of the detuning of the spontaneously emitted photon, the Rabi frequency of the microwave field and the dipole moment matrix element alignment p on the CPP. 2D sub-half-wavelength atom localization is obtained and the spatial resolution is improved significantly compared with cases with no quantum interference.


In the crystal structure of the title compound, C(11)H(16)N(4)OS, the phenyl ring and the thiosemicarbazone moiety from a dihedral angle of 7.7 (1) degrees. The crystal structure is governed by N-H.O and O-H.S hydrogen bonds leading to the formation of a two-dimensional network.


. Abstract E-world is characterized by the preference for electronic options, which provides more efficient, faster and more convenient solutions than the traditional way. The emergence of the Internet restructured and made dynamic the tourism sales chain, creating the concept of e-tourism. Online tourism services have made a significant contribution to the growing popularity of individually organized trips by providing convenient and quick information, comparison and transaction opportunities. At present, the former traditional and new, modern booking options live side by side. Based on hotel booking statistics, in our study we examine the characteristics of direct and indirect, as well as offline and modern online booking. The proportion of direct (45.6%) and indirect (54.4%) bookings was balanced in the hotel, while 71.2% of reservations were connected to offline channels. It is likely, however, that online interfaces play an important role in searching and getting information - the literature also proves this.

With the rapid development of ports, the port industry continues to focus on the function, service, and value chains. Further accelerating the high-quality development of ports has become crucial to promoting urban construction and economic development. Dongjiakou Port is an important shipping and logistics hub in the center of the Bohai Economic Rim and the Northeast Asia economic circle, which has superior deep-water resources. Through active transformation and upgrade, it has become an international trade hub with sustainable practices. This research examined Dongjiakou Port as a case study and employed a grey prediction model to analyze and predict port throughput and to determine the indicators and impact factors for a green port. In addition, the grey model and principal component analysis were used to predict the throughput of Dongjiakou Port from 2021 to 2025, and the effectiveness of the model was verified by comparing the predicted and actual throughput from 2014 to 2020. In addition, this research also provided suggestions for the sustainable development of ports from the aspects of port planning, port cargo structures, and effective port governance and development. The prediction model can provide support for future port planning and port design, to a certain extent, and can also provide references for predicting port throughput and promoting the construction of new ports and sustainable port development.


In this paper we describe a competitive way to learn and review concepts: a championship based on quizzes. Students will compete in "duels" against other students in an instant messaging channel where a program will be launching questions; the student that answers first will get the point. And the first to reach a series of points will win the game. We have designed, implemented and tested a (free) software to automate the entire process of the championship, allowing students to choose the times of their matches, throwing questions to the channel, keeping logs, driving classifications, providing feedback to the lecturer about performance and questions, etc. From several testing championships performed, we have noticed a high involvement and motivation by students. Being the process automated, lecturers do not have to spend much time on this activity even if it takes place outside the classroom (they only have to worry about uploading questions with their answers and keep track of possible revisions students may ask for).
