Friedel–Crafts reactions with halogenomethinyltricobalt enneacarbonyls afford a useful route to a wide range of aryl clusters, RCCo3(CO)9. The usefulness of g.l.c. in their purification is emphasised. Substitution is predominately in the para-position but exceptions occur when the aryl substituent is small (e.g. F). In one case (R = ClC6H4) both ortho- and para-isomers were isolated. Methods for determining the structure are described and the inductive-mesomeric effects of a Co3C cluster evaluated.


Through a so-called dynamic packing injection molding technology(DPIM),imposed the back and forth in the shear stress in melt blending system to improve the multi-walled carbon nanotube(MWCNT)and high-density polyethylene(HDPE)plastic injection products structure and properties.Polarizing microscope showed that the shearing in the process of forming contribute to carbon nanotubes to the dispersion in the HDPE,the size of MWCNTs aggregation in the DPIM bar was significantly less than that in the bar obtained by conventional injection.Mechanical properties test showed that tensile strength and modulus of the product by dynamic pressure increased,but elongation at break decreased.Addition of 1% MWCNTs caused an increase of 20% in both of tensile strength and modulus.Moreover,different scanning calorimeter(DSC)showed the crystallization temperature of composite was improved as a result of the crystallization of carbon nanotubes to act as a nuclear point.


A 40Gb/s field trial using 12.5GHz-spaced multi-carrier 10Gb/s signals over an installed 752km WDM-link was successfully completed. Results show that the system has a superior CD and similar PMD tolerance compared to typical 10Gb/s systems.


The present study was carried out to evaluate the relative biological activity of six treatments. Four nanoparticles (chitosan, Hydroxyapatite, chitosan hydroxyapatite and silver hydroxyapatite), one bio-agent effective microorganisms (EMs) compared to one synthetic acricide (bifenzata) were tested against the female adults and eggs of Tetranychus urticae and its predatory mite Amblyseius gossipi using standardized method of bioassay under laboratory conditions. Effect of the tested agents on the activity of carbohydrates enzymes, total lipid and total protein content were determined. The results revealed that chitosan (NPs) showed significantly adulticidal activity against T. urticae. Furthermore, EMs was the most effective treatment on the eggs of T. urticae followed by bifenzata under laboratory conditions. Therefore, nanoparticles and EMs appeared to be highly safe and selective against Amblyseius gossipi. This study suggests the possible use of nanoparticles as safe alternatives to conventional acaricides and compatible with integrated pest management practices. They might be contribute to future applications in pest control for sustainable agriculture.


Is the U.S. vulnerable to a full-blown dollar crisis? Why are international finance economists scared and jittery, but domestically-oriented macroeconomists much less concerned?


Population aging is progressing at the highest rate historically, leading to an increased morbidity. Therefore, higher levels of collaborative pharmaceutical practice (CPP) and interprofessional collaboration (IPC) are expected to provide the necessary improvement to the healthcare system performance. For a strong body of literature to be built in the area of CPP and IPC, methodologically sound research studies must be completed, using questionnaires with well-developed psychometric properties. Therefore, the objective was to develop a questionnaire aimed at researching the attitudes of the elderly (65+) towards IPC and CPP. A structured questionnaire was developed using the Delphi method by a team of experts (n=8) within four rounds of meetings. Reliability, question correlation and factor analysis were used for questionnaire validation. Questionnaire validation (n=40) determined the Cronbach's Alpha to be at the high value of 0.774, and reliability analysis of questionnaire's scales on the total sample (n=185) in the five Geriatric Centers confirmed a relatively high value of 0.736. Interclass correlation coefficient values were highly significant (ICC=0.749; p<0.01), which confirmed questionnaire compactness regarding CPP. An exploratory factor analysis highlighted 2 significant factors explaining 53% of the entire model variability. Both questionnaire validation (n=40) and total sample analysis (n=185) confirmed the appropriateness of the developed questionnaire.


Contextual advertising is an important revenue source for major service providers on the Web. Ads classification is one of main tasks in contextual advertising, and it is used to retrieve semantically relevant ads with respect to the content of web pages. However, it is difficult for traditional text classification methods to achieve satisfactory performance in ads classification due to scarce term features in ads. In this paper, we propose a novel ads classification method that handles the lack of term features for classifying ads with short text. The proposed method utilizes a vocabulary expansion technique using semantic associations among terms learned from large-scale search query logs. The evaluation results show that our methodology achieves 4.0% ~ 9.7% improvements in terms of the hierarchical f-measure over the baseline classifiers without vocabulary expansion.


"Our book deals with the laboratory diagnosis of all the major bleeding disorders, based on a clinical approach... We have tried to be practical and have aimed our remarks at the clinical pathologist, the hematologist, and the medical technologist." Thus the authors summarize the latest entry to the expanding field of books on hemorrhagic disease. This is a fine volume, and I think that the authors have met their goals. No one can be admitted to the sacred blood rites of "clottology" without demonstrating his disdain for his fellow coagulationists, but, risking expulsion from the clan, I must state that I enjoyed this volume, which I read word by word and cover to cover. Three major strengths commend this book. The authors begin with a superior history of the field. They then describe in meticulous detail the laboratory procedures used at the Mayo Clinic. And they provide many interesting case


Reaction of amines with carbon tetrachloride has received considerable attention1–3, and it has been pointed out that the presence of copper metal is substantial for the reaction4,5. On the other hand, oligomerization of ethylene was studied by amine and carbon tetrachloride system, and discussed whether any metal or metal salts can play a role for initiating the reaction6,7. Polymerization of vinyl monomers was also carried out by imidazole and carbon tetrachloride system8,9.


Different music performances of the same score may significantly differ from each other. It is obvious that not only the composer's work, the score, defines the listener's music experience, but that the music performance itself is an integral part of this experience. Music performers use the information contained in the score, but interpret, transform or add to this information. Four parameter classes can be used to describe a performance objectively: tempo and timing, loudness, timbre and pitch. Each class contains a multitude of individual parameters that are at the performers' disposal to generate a unique physical rendition of musical ideas. The extraction of such objective parameters is one of the difficulties in music performance research. This work presents an approach to the software-based extraction of tempo and timing, loudness and timbre parameters from audio files to provide a tool for the automatic parameter extraction from music performances. The system is applied to extract data from 21 string quartet performances and a detailed analysis of the extracted data is presented. The main contributions of this thesis are the adaptation and development of signal processing approaches to performance parameter extraction and the presentation and discussion of string quartet performances of a movement of Beethoven's late String Quartet op. 130. music performance, music performance analysis, automatic tempo extraction, loudness analysis, timbre analysis, string quartet performance, audio content analysis, audio-to-score-matching


The paper addresses the epidemiologic data of the death of pigs during the period of 2002 to 2009 following the ingestion of botulinum neurotoxin type C. This neurotoxin was present in food residues originating from restaurant and hotel kitchens, stored in barrels without shelter from the sun and administered in a collective trough without prior thermal treatment. Animals which died at different ages showed clinical signs of botulism characterized by flaccid paralysis, weight loss, anorexia, weakness, lack of coordination, locomotion difficulties with the evolution of lateral recumbency with involuntary urination and defecation. No alterations were observed at postmortem and histological examination. The bioassay with serum neutralization in mice was carried out on samples of intestinal contents from pigs affected and revealed the presence of large quantities of botulinum toxin type C.


Taking cutting landslide of expansive soils controlled by discontinuities as an example,a simple mechanical model considering water swelling is proposed,which takes the strain-softening and water-softening of slip surface materials under the condition of rainfall into the consideration.Furthermore,the mechanism of the cutting slope of expansive soils is analyzed by catastrophe theory.Many factors trigger landslide,such as moisture content and stiffness ratio.The results show that evolution process of landslide is resulted from internal and external factors,and the cause of rainfall resulting in softening-swelling of discontinuities belongs to the external triggering factors.The water controlling should be taken into consideration in the process of reinforcing cutting slope.


WSNs are composed of many autonomous devices using sensors that are capable of interacting, processing information, and communicating wirelessly with their neighbors. Though there are many constraints in design of WSNs, the main limitation is the energy consumption. For most applications, the WSN is inaccessible or it is unfeasible to replace the batteries of the sensor nodes makes the network power inefficient. Because of this, the lifetime of the network which has maximum operational time is also reduces. To make the network power efficient, different power saving/reduction algorithms are proposed by different authors. Some of the authors have achieved the low power consumption by modifying like encryption & decryption algorithms, Routing algorithms, Energy Efficient Algorithms, Compression and decompression algorithms, minimizing control packets, and many other different power reduction algorithms. Among many algorithms, we have chosen data compression techniques aiming different targets like memory, power & bandwidth reduction. To achieve our objectives, we have worked on Huffman coding compression algorithm and updated the algorithm by including one's complement, XOR operations and finally named as Modified Huffman Coding. The performance of the proposed model is analyzed and it is observed that, information is maximum compressed which consumes less computational power, thereby increasing the battery life.


Abstract : Modern Army Trucks have undergone an evolution that has spanned sixty-plus years and countless iterations of drive-train and system technology. From the erstwhile mechanically controlled internal combustion engines of days gone by to the robust electronically managed networks of today's warhorse tactical wheeled vehicles, the ever-present requirement to integrate and maintain these technologies remains. For some systems in the Army's inventory, this is a more pressing problem. A great many vehicles in Army service lack the network based electronics to integrate new age electronic control modules (ECU's). This missing ingredient is paramount in enabling the use of embedded diagnostics computing to troubleshoot the entire system via networked communications, and to host diagnostics software such as interactive electronic technical manuals (IETMs). The costs associated with integrating these electronic networks into Army trucks are high, sometimes running into the tens of thousands of dollars per vehicle. For lower cost platforms such as High Mobility Multi-purpose Wheeled Vehicle (HMMWV) (figure 1), this cost is prohibitive. As technologies in the areas of engine and transmission evolve to be available as only electronically controlled subsystems, the need to create an affordable, scalable module to serve as a low cost electronic integration point becomes necessary. The approach calls for this module or "data bus in a box" to have standard vehicle and electronic information interfaces, suitable processing to handle many data inputs, designed-in scalability for non-electronically controlled sensor inputs, and the requisite ruggedization properties to handle the rigors of today's military environment.

Biofilm slime layer is one of the advanced biological treatment technologies for industrial and municipal wastewater treatment with the capacity to reuse of treated water for agricultural purposes. Bacterial, fungal and algal biofilm slime layer were grown on the interior surfaces of polyethylene pellet (carrier) and suspended in municipal wastewater for organic pollutants removal. Bacterial species (Pseudomonas aeruginosa, Bacillus megaterium, Sphingobacterium thalpophilum), fungal species (Penicillium citrinum, Aspergillus niger, Trichoderma harzianum) and algal species (Nostoc linckia, Scendesmus dimorphus) were used separately for biofilm slime layer growth under controlled laboratory conditions (pH, temperature, and aeration). Bacterial biofilm layer thickness was measured and recorded 9, 6 and 5 mm respectively as compared with 3mm for control group through the retention time of 16 day. Bacterial P. aeruginosa biofilm slime layer showed an efficiency for COD, TOC, NO3 and PO4 removal after 24 hour of 75%, 65%, 69% and56% respectively while the removal rates of the same factors using the fungal biofilm layer of P. citrinum was 83%, 78%, 53% and 60% after 48 hour respectively. The algal biofilm reactor with S. dimorphus showed the highest percentage removal rate of total nitrogen 93% as compared to control group 87% after 72 hours of treatment due to the biofilm slime thickness of S. dimorphus 7.5mm as compared to the thickness of the N. linckia slime layer 5.3mm. Mixture of microbial species biofilm layer was used for wastewater treatment through 18 and 24 hours, using aerobic and anoxia. The mixture of microbial species biofilm layer showed removal rates for TOC, COD, and TN of 90%, 83%, and 59% respectively in an aerobic condition, while the removal rates were 66%, 52%, and 84% in an anoxic condition. From the above results, one concludes that controlling the biofilm slim layer is a promising technology for municipal wastewater treatment, as long as it is used under the suitable conditions.


Induction motors driving the agitators in pulp tanks are affected by the leakage of pulp that coats their inter-fin channels, blocks the air inlets of the fan cover, or partially floods them. This paper presents a complete thermal evaluation of TEFC induction motors during these abnormal conditions. A totally enclosed fan cooled (TEFC) induction motor fitted with 12 thermocouples was tested in the different situations of interest, including pulp spilled over the frame, in the air intake, and partially flooding it. Winding, frame, and bearing temperatures were measured. These results are used to determine the required oversizing of an agitator motor in order to assure that the motor will not fail even if the inter-fin channels become obstructed with spilled pulp.


High performance XY-table is commonly incorporated into integrated circuit (IC) manufacturing and packaging equipments. In order to achieve a higher acceleration, a novel XY positioning table redundantly driven by one-side dual linear motors was proposed. The redundant drive system commonly suffers from synchronous motion precision problem at high speed and acceleration rates. The mathematical model of dual linear motors redundant drive system along X-axis direction was given. Meanwhile, motion controllers were designed based on model reference adaptive control and adaptive fuzzy control algorithms to assure the synchronous motion precision. The simulation results show that the control system has better static and dynamic performance and higher synchronous motion precision at a high acceleration profile motion.

OBJECTIVE
To identify stressors affecting international students' mental health during the COVID-19 pandemic.

PARTICIPANTS
Twenty-two international students from 10 countries and 17 US institutions participated.

METHODS
Participants were recruited from a larger study examining the wellbeing of young adults during the pandemic.

RESULTS
Four main stressors were identified: (1) Uncertainty and anxiety induced by decisions and policies in response to COVID-19; (2) Fears regarding xenophobia; (3) Limited understanding by educators and school staff of international students' unique challenges; (4) Greater awareness of racial and cultural identity.

CONCLUSION
The pandemic has contributed to additional stressors for international students. Educators and mental health professionals may help support international students' mental health by gaining basic knowledge about common stressors and directly acknowledging the challenges, educating international students on race and racism and supporting anti-racism efforts, and encouraging the creation of shared affinity spaces and increasing psychoeducation to promote resilience.


THE great temples of ancient Egypt are monuments to the state cults rather than to personal piety. In theory it was the King himself who officiated in every temple, daily adorning the image of the resident deity, and presenting offerings. In practice this task was delegated to the higher ranks of the priesthood and took place in a sanctuary deep within the temple where no observers were permitted. The deities were honoured to ensure their continuing benevolence towards Egypt, so the daily ritual was carried out on behalf of the whole community, with little place for any expression of individual needs.


Purpose – Provides two hybrid methods for the aerodynamic design of cascade profiles, of which the design constraints are the combination of aerodynamic and geometric conditions.Design/methodology/approach – In the first method, the design constrain is composed of the velocity (or pressure) distribution on part of the blade surface and the geometry of the rest part. In the second method, the aerodynamic load distribution, i.e. the pressure difference between the suction and pressure surfaces, and the blade thickness distribution are employed as the design constrain. These constraints, together with all the other boundary conditions, are involved in the stationary conditions of a variational principle. The solution domain, i.e. the blade‐to‐blade passage, is transformed into a square in the image plane, while the blade contour is projected to a straight line; thus, the difficulty caused by the unknown geometry of profile is avoided. Finite element method is employed to produce the calculation code.Findings...


Diabetes is recognized to lead to a series of metabolic abnormalities in the body. These alterations will affect balance, body composition, and cardiovascular performance, heightening the risk of various medical complications. The problem is that the primary instruction for those with diabetes is to monitor glucose levels, paying very insufficient consideration to other fundamental factors and health profiles that could influence the quality of life in these individuals. Identify body composition, balance, and cardiovascular components in controlled type two diabetics compared to an age-matched control group. 15 participants with controlled type II diabetes without peripheral neuropathy (CT2DM) and 18 non-diabetic subjects control (CG) were recruited. Both groups had an age average of roughly 56 years old. The CT2DM subjects had an average A1c level of 6.7+/-0.5%. Body composition, cardiovascular, and balance data were collected, analyzed, and compared among groups. Minimal alterations in balance components, body composition and cardiovascular factors were identified in the CT2DM group aside from higher SBP values and decreased BBS scores contrasted to the CG group. We can attribute the analogous outcomes in both groups to CT2DM participants managing their diabetes effectively. Our examination has prompted us to establish that the cardiovascular and balance components in middle-aged Latinx-Hispanic participants with CT2DM are proportionate to CG subjects because of effectiveness in dealing with diabetes. Further, we encourage establishing more age appropriate and complex assessment tools to identify early adaptations caused by diabetes.


Bupropion is a novel antidepressant agent. In the present study, an attempt was made to gain some insight into the mechanism of the drug's antidepressant activity. In vitro studies revealed that bupropion was a weak, competitive inhibitor of norepinephrine (NE) uptake into rat hypothalamic synaptosomes and of dopamine (DM) uptake into rat striatal synaptosomes, having IC50 values of 6.5 ± 0.6 × 10−6 M and 3.4 ± 0.4 × 10−6 M, respectively. At 1 × 10−5 M, the drug produced a 20 ± 3% inhibition of serotonin (5‐HT) uptake into rat hypothalamic synaptosomes. The drug was also a weak inhibitor of the ATP‐Mg+2 stimulated uptake of NE and DM into synaptic vesicles of whole rat brain, having IC50 values of 3.3 × 10−5 M and 6.0 × 10−5 M, respectively. Bupropion had no dose‐dependent effect on the spontaneous release of NE, DM, and 5‐HT from these synaptosomal preparations in concentrations as high as 1 × 10−4 M. Brain monoamine oxidase (MAO) activity in vitro was not affected by concentrations of the drug ranging from 10−7 M to 10−5 M. Bupropion was also without effect on brain MAO, 1 hr after i.p. doses in rats as high as 100 mg/kg. The ED50 value for bupropion necessary to inhibit the uptake of 3H‐catecholamines by 50% into synaptosomes incubated in the serum from rats treated with the drug was 40 mg/kg i.p., while its ED50 value for antidepressant activity, as judged by the ability of bupropion to reverse the immobile posture of "helpless" rats, was 8 mg/kg i.p. These neurochemical properties of bupropion on uptake of biogenic amines and on MAO activity serve to distinguish it from other antidepressant drugs of the tricyclic and MAO inhibitor classes.

With 184 L/S-ratio determinations and 132 creatinine determinations in amniotic fluid we tried to show a connection between these parameters and sonographically provable changes of placental structures. We found no relationship between placental grading and fetal lung and renal maturity by statistical processing of the results, considering gestational age. There is between L/S-ratio and creatinine determinations no statistical relationship, too.

The article deals with problem of the fresh waters salinization in view of its relevance for normal functioning of the aquatic ecosystems, development of different branches of industry and agriculture, and human health. Attention is focused on the fact that the fresh waters' salinization inevitably results in decrease of the ecosystem services scope. The main factors and anthropogenic sources of influence on total dissolved solids in the fresh waters and metamorphosis of their ion composition are considered. It is stated that climate changes potentially affect and will affect the surface waters mineralization in future owing to volume and frequency of the atmospheric precipitation, intensity of the rocks and minerals weathering, the ground feeding of the rivers, the marine water penetration into the estuaries along with reducing of the river water yield, etc. The possible impact of mineralization changes on migration of substances from bottom sediments into the water thickness, that is on the intensity of its secondary pollution, is discussed. This impact can be direct and indirect. First of all, it concerns the migration ability of metals in bottom sediments. Elevated content of Na+, Ca2+ and Mg2+ in water intensifies migration of metals of the exchangeable fraction of bottom sediments. The indirect effect of elevated mineralization is expressed in the oxygen regime of the water bodies, which usually deteriorates in the near-bottom water layers of deep lakes and reservoirs, mouth areas of the rivers and estuaries. The dissolved oxygen deficit becomes usual, anoxic conditions are formed, which favor release of Fe(III) and Mn(IV) from oxyhydroxides or the oxide fraction of the bottom sediments. A review also considers some aspects of potential impact of the fresh waters salinization on survival of the aquatic plants and animals and biodiversity.


In recent years, researchers have been exploring the applications of noisy intermediate-scale quantum (NISQ) computation in various fields. One important area in which quantum computation can outperform classical computers is the ground state problem of a many-body system, e.g., the nucleus. However, using a quantum computer in the NISQ era to solve a meaningful-scale system remains a challenge. To calculate the ground energy of nuclear systems, we propose a new algorithm that combines classical shadow and subspace diagonalization techniques. Our subspace is composed of matrices, with the basis of the subspace being the classical shadow of the quantum state. We test our algorithm on nuclei described by Cohen-Kurath shell model and USD shell model. We find that the accuracy of the results improves as the number of shots increases, following the Heisenberg scaling.

The International Telecommunication Union (ITU) has and continues to develop globally harmonized standards that have progressively enhanced the viewing and listening quality of all media. The ITU championed the global switch to digital broadcasting and the introduction of high-definition television (HDTV). It also pioneered ultrahigh-definition television (UHDTV), high-dynamic range television (HDR-TV), and the developing standards for advanced sound systems, which together bring increased realism and a dramatic increase in the quality of images and sound no matter how they are distributed.


The allometric changes characterizing the growth of the deutocerebrum (midbrain) of the American lobster (Homarus americanus) are studied using computerized three‐dimensional reconstructions of serial brain sections. During the embryogenesis of the midbrain, the paired accessory lobes (higher order processing areas) appear later than the paired olfactory lobes (primary olfactory centers), but the former grow faster from their emergence until metamorphosis. The accessory lobes, as they enlarge, shift progressively from a medial to a posterior position in the lateral deutocerebrum. In early juvenile stages the accessory lobes are one of the largest neuropils of the brain. However, these lobes stop growing in adult animals, whereas the brain and olfactory lobes continue to enlarge, albeit at a slow rate.


An improved borehole shear test (BST) instrument was utilized to obtain the shear strength index of the soil layer in-situ. The results show that the shear strength index of the saturated silty clay measured by the improved borehole shear apparatus has a good linear correlation with the normal pressure, and the correlation coefficient can be greater than 0.98. The testing results were also compared with those obtained by the direct shear test (DST) in the laboratory. It was found that when the soil layer has a depth of less than 8.75m, the difference in the internal friction angle by the BST and DST is small. The former is 8%–33% larger than the latter. The deviation in the cohesion is obvious, which ranges from 20% to 61%. For the soil layer deeper than 8.75m, the situation is different. The difference in the cohesion measured by the two methods is small, which ranges from 8% to 9%, while the difference in the internal friction angle is distinct, and reaches 62%–85%.

An extensive experimental programme in both laminar and turbulent flow was undertaken to examine the validity of all of the major implications of the model of the pulsed ultrasonic Doppler velocimeter for turbulent flow developed in part 1 of this investigation. The turbulence measurements were made in fully developed flow at the centre of a 6·28 cm diameter pipe. The Reynolds number of the flow ranged from 6000 to 40000. The carrier frequency of the ultrasonic velocimeter was 4·7 MHz. Measurements of the turbulence intensity and of the one-dimensional velocity spectra made with the ultrasonic velocimeter are compared with the analysis and with the actual quantities as measured by a hot-film anemometer. The experimental results are in agreement with theoretical predictions. Measurements of one-dimensional turbulence spectra with reduced ambiguity spectra made by the two sample volume methods described in part 1 are presented. The results verify the analysis and indicate that an improvement in the useful dynamic range of the velocity power spectrum of nearly three orders of magnitude can realistically be achieved.


NdCl 3 FeCl 3 graphite intercalation compounds were synthesized by molten salt exchange method. The state of the intercalates and the relative contents of Nd, Fe, Cl, C in the product were determined by X ray photoelectron spectroscopy(XPS). From the XPS data, it is concluded that the binding energy of Fe2p electrons is about 711 20~710 3 eV, the binding energy of Nd3d electrons is about 983 08~983 20 eV, and Fe in the product has two valence states (Fe 3+ and Fe 2+ ).


Intense terahertz radiation is promising for material control and understanding of the THz-matter interactions is important research topic. We irradiated Ge-Sb- Te phase change material thin films with a train of THz pulses from a free electron laser and found that the surface changes that are damage as a precursor to ablation and the undulations were induced without amorphization. The undulation pattern is thought to be a sort of laser induced periodic structure (LIPSS) that is one of important phenomena in the field of laser material processing. Absence of amorphization implies that photo- or electrical-excitation plays an important role for fast phase change operation.


Isotactic polypropylene (iPP) has good comprehensive properties, viz. easy processing, high heat resistance, and good stiffness, etc., and in turn is widely used as a commodity plastic. However, under conventional processing conditions, iPP crystallizes into sizable spherulites with few tie molecules between spherulites. With such a crystalline texture, iPP exhibits very low impact toughness, especially at lower temperature, which restricts its more extensive application. Therefore, toughening of iPP has always been an open research. Up to now, four routes have been taken to improve impact strength of iPP, including copolymerizing with other olefin monomers, blending with rubber or thermoplastic elastomer, compounding with organic or inorganic fillers (e.g., nanoparticles), and adding β-nucleating agent. Without doubt, the modified iPP, more or less, increases its toughness. The enhancement of toughness is, unfortunately, at sacrifice of other properties, e.g., strength, heat resistance, etc. There are extremely few successful examples for simultaneously efficiently reinforcing and toughening iPP. It has been well established that for iPP oriented crystals (i.e., shish-kebabs) can bring out notable reinforcement on iPP, while β-form crystals of iPP can greatly increase its toughness. Flow (shear, elongational, or mixed) would induce formation of shish-kebabs whose content is governed to shear rate, shear duration, and molecular species and weight, etc. On the other hand, β-form crystals can be high production generated by addition of β-nucleating agent under quiescent conditions. This type of iPP crystals causes high toughness due to the β-R polymorphous transition and the loose structure of β-form crystals compared with R-crystals in favor of absorbing impact energy. Naturally, an idea arises that combination of flow-induced molecular orientation crystallization and β-nucleant-induced β-form crystals produces efficient reinforcement and toughening on iPP. However, as a matter of fact, there is not any example of it in the open literature. Themajor reason is that the coexistence of a β-nucleating agent and a shear flow at above a certain but low level of shear rate depresses β-form nucleation. Huo et al. performed a delicate study on iPP crystallization with β-nucleating agent and observed that as the shear rate rises, the content of β crystals constantly reduces, more greatly for higher nucleating agent content, showing counteraction between shear and β-nucleating agent for β-form formation. Apparently, it is a great practical challenge to prepare iPP parts withhighmolecular orientation and highβ-crystal proportion for the purpose of both strength and toughness enhancement. In the present work, we attempt to fabricate iPP with considerably increased strength and toughness, for the first time, utilizing the counteraction of shear-induced orientation crystallization and β-nucleating agent on β-form nucleation. The crystallization process of iPP is manipulated by two stages: one is flow-induced crystallization for high molecular orientation, and the other is β-nucleating-agent-induced nucleation for highβ-crystal content. More specifically, the oscillation shear supplied by an oscillation shear injectionmolding (OSIM) (its detailed definition is included in the Experimental Section) is imposed on β-nucleated iPP melt in the mold during injection molding. Initially, due to occurrence of shear flow and β-nucleating agent, β-form formation is restrained; thereby, the oriented R-crystals first form in the skin and intermediate layers of the sample.When the gate of the mold freezes, the shear ceases, and hereby, β-nucleating agent revives. The remainder of iPP melt in the core layer undergoes β-nucleation-induced crystallization. The results demonstrate that a large amount of shish-kebab structure appears in the surface and intermediate layers of the sample; at the same time, numerous β-form crystals form in the core layer, thus leading to prominent reinforcement and toughening for iPP.


This thesis covers the following aspects: 1. The E/R notation and the REA model notation in UML for accounting and a retail shop enterprise, 2. Analysis of enterprises in general and enterprise solution, 3. Construction of enterprise solutions using Microsoft architecture and Navision Jamaica, 4. In the end some suggestions are presented for improving modeling enterprises and enterprise solutions. Rationale Present-day business life requires software applications to perform management solutions for enterprises. These software applications are named ent rprise solutions. Enterprise solution improves an enterprise's infrastructure and helps to run a business. Rapid development of information technologies creates a shift from software engineering to modeling engineering. Now the process of analysis and modeling of the enterprise domain plays a key role in construction of enterprise solutions. This thesis examines some recent techniques for business modeling and strategies for constructing enterprise solutions. The goal of this project is to indicate possibilities for enterprise modeling. Subjects of conceptual modeling and ontologies are emphasized as having big potential for enterprise modeling and future enterprise solutions. Report structure The report is structured as follows: • Chapter 1 provides an introduction to the report along with brief description of the content; • Chapter 2 examines the E/R notation and REA notation for enterprise modeling. A REA model of a retail shop enterprise is taken as a study example. Possibilities to represent REA model in UML notation are suggested; • Chapter 3 explains artifacts of business enterprise and enterprise solution. General aspects of enterprise functioning are described in order to establish a base for modeling an enterprise solution. The chapter defines the role of enterprise solution in enterprise functioning. The chapter shortly covers requirements for


The ground level enhancement (GLE) of 14 July 2000 observed in the cosmic ray intensity has been examined. The event was recorded only by neutron monitors. It has a complex intensity-time structure. The northern hemisphere stations (Thule, Goose Bay, and Oulu) recorded abrupt increases earlier by 10 minutes than those in the southern hemisphere. Due to the difference in sensitivity at rigidity less than ~3 GV, the considered detectors recorded different increases in count rates relative to galactic cosmic ray background. This paper presents the study of GLE associated with the X5.7 solar flare. The rapid change of arriving particles were anisotropic during the onset of the event; it become isotropic during the declining phase of the event, where only low energy protons remained. In addition, the observations of energetic solar particles and interplanetary parameters have been examined.

It is well known that braiding construction is a useful reinforcement configuration in three dimensional composite. We previously presented simulation techniques for the basic flat and cord braiding mechanisms, and discussed the relationship between braiding construction and fabricating condition. However, it is difficult to fabricate the braiding construction with a complex cross section using the usual braided machine. In this paper, we propose a new braiding mechanism for fabrication of three dimensional braiding construction in which the orbit of the bobbin on the plane has no limitations. We also clarify the feasibility of this braiding mechanism.


The current global political atmosphere is steeped in fear of, and intense rhetoric about, political violence and "terrorism." Amidst this turbulent environment, it is clear that scholars and practitioners need to get beyond the manufactured fear and the hysterical rhetoric, peddled by what we call the corporate-state-military-media complex (or simply, the "power complex"), and instead seek a deeper understanding of political groups that defend or deploy the tactics of economic sabotage (property destruction) or armed struggle in order to change repressive and violent social structures (Best and Nocella 2004; Best and Nocella 2006). Such understanding is important to slow down and reverse the current trend among legislative and policymaking bodies and political leaders who increasingly marginalize, demonize, and exclude radical opposition groups from arenas of debate. Law enforcement agencies and "counterterrorism experts" around the world see no alternative to fierce repression of dissenting groups, but this approach typically backfires, producing even more resistance and multiplying the very tactics it seeks to eliminate.


In the early years of Republic of China during the transformation from a traditional national system to a modern one,there was an influential controversy on whether federal system was suitable in China.When most newspapers and magazines supported federal thought,The Great Chung Hwa Magazine,chiefly edited by Liang Qichao,gave a different view that federal system was not good to remain national unity,and that the civil-elected provincial governors would do more harm than good.Meanwhile,it opposed the assertion of "canceling provinces for centralization",calling for a new political system that was neither a federal nor a central one.


The utility model discloses a water tank structure with a wireless power transmission electric appliance. The water tank structure with the wireless power transmission electric appliance comprises a water tank, a passive device and an emitter. The passive device is provided with a receiver. The emitter transmits electrical energy to the receiver by mutually generating a resonance state with the receiver. The passive device is arranged in the water tank, and the emitter converts electric power into an electrical signal, converts the electrical signal into resonance energy and emits the resonance energy outwards. The receiver and the emitter have corresponding electrical resonance characteristics so that the receiver can receive the resonance signal outputted by the emitter and convert the resonance signal into an electric power output so as to supply electric power loads needed by the passive device.

Load balancing is the process of improving the performance of a system through a redistribution of loads among the processors. In this paper the authors present the stability analysis of a load balancing algorithm based on graph coloring. In this algorithm the processors use local knowledge for the purpose of load balancing. Unlike threshold based algorithms whose efficiency depends on the threshold level selected, the graph coloring based load balancing algorithm does not use any such global parameter. Furthermore, it uses the edge coloring concept to pair the processors. This avoids the selection/rejection operations encountered in many load balancing algorithms proposed in the literature. Also, there is no central controller and the algorithm is easily adaptable to changes in the system configurations.

Sensor based VRT liquid fertilizer application is a suitable way to apply the nutrients for soil management of various crops. Time and resources can be saved using this technology but due to the special characteristics of cereal and tree crops like paddy and oil palm, dedicated designs of VRT liquid fertilizer applicators are needed to fulfill the nutritional requirement of respective crops. The proposed design of VRT liquid fertilizer applicator involves soil fertility sensors, speed sensor, flow control valves, flow sensors and pressure sensor. Design considers the variable fertilizer flow compensation with change in forward speed of machine between 2.5-3.5 km/h. Also this design offers the transfer of data from electronic controller to the external computer for record and performance testing of machine by computing the lag times of flow control valves and application error of machine. Originally, the design is for tree crop; however, with a slight modification in controller's program, this will also be suitable for cereal crops like paddy. To apply the fertilizer, three DC pumps of 6.89 bar pressure and 5 L/min flow rate were used in simulation with the flow lines of 6 mm internal diameter. Flow simulation revealed that the system was able to achieve the 0.06 L/s at 13.73 m/s velocity at nozzles 1 and 2 (full cone nozzles) while nozzles 3 and 4(flat fan nozzles) were delivering the same flow rate but at a little high velocity of 13.94 m/s. A comparatively uniform distribution of fertilizer application may be achieved using flat fan nozzles.


Usability evaluation of a website is a key element in identifying the areas where the end-users might experience problems while interacting with it. The usability parameter has a great impact on the performance of a website, an organization's image, user satisfaction, and their intention to revisit the site. In the recent past, there has been a tremendous increase in the use of websites for seeking requisite information about admission to various courses offered by higher education institutions. There has been a lack of an effective and efficient set of heuristics that can be used to evaluate the usability of these education institution websites. The present study differs from earlier studies by providing a new set of 43 usability heuristics and categorizing them into eight distinct factors on the basis of their empirical validation. These eight identified factors exhibit strong psychometric properties and are ease of navigation, design quality, information architecture, credibility, functionality quality, content quality, simplicity, and learnability. The findings of this study are highly useful for the website designers and evaluators of higher education institutions' websites, who are concerned with evaluating and improving the usability of these websites. The findings of this study have theoretical as well as practical implications.


Despite the dominant discourse of the Moroccan immigrant women in the Netherlands who were interviewed that religion "does not change" and that "Islam is not dependent on locality," they mention substantial changes in religious celebrations. Whereas some of these changes are also discernable in Morocco, immigrant women tend to ascribe these transformations to their migration to the Netherlands. In this article, the religious year cycle and their major changes are described and analysed.

Methylmercury concentrations [MeHg] in whole water were measured in 28 prairie wetland ponds in central Saskatchewan between 2006 and 2012. Ponds fell into four land use categories (established grass, recent grass, traditional cultivated, and certified organic cultivated) and two water level patterns ("Mainly Wet" ponds stayed wet at least until October and "Mainly Dry" ponds dried up each summer). Despite similar atmospheric Hg deposition, average [MeHg] and proportion of total Hg that was MeHg (%MeHg) were higher in water from ponds surrounded with established grass or organic farming; this trend may be driven by high [MeHg] at one Organic site. A stronger relationship was observed with water level patterns. Average [MeHg] and %MeHg were significantly higher in Mainly Wet ponds compared to Mainly Dry ponds. Higher [MeHg] in Mainly Wet ponds were correlated with much higher dissolved organic carbon (DOC) and sulfate (SO4−2) concentrations and higher specific UV absorbance of DOC. We suggest that prairie wetland ponds may not fit the accepted paradigm that wetlands with high [SO4−2] show inhibition of Hg methylation. Our work suggests controls such as the chemical nature of DOC or redox fluctuations in hydrologically dynamic systems may be important in determining net [MeHg] in these sites.


Introduction to bead modelling The size and detailed shape of rigid macromolecules or particles can be inferred from the properties of their solutions or suspensions. Some of these are hydrodynamic properties, such as the sedimentation coefficient, s, the translational diffusion coefficient, D,, rotational diffusion coefficients, D,, and relaxation times, z, and the intrinsic viscosity [q]. There are also equilibrium solution properties, including the angular dependence of radiation scattering, P (O), the radius of gyration, R, and the covolume, u. Theoretical formalisms, implemented in adequate computer procedures, are required to correlate global structure (size and shape) with solution properties. In some instances, the overall shape can be conveniently described by revolution or triaxial ellipsoids, for which theory and simple procedures are available [1,2], but in many other cases the ellipsoidal shape is clearly inadequate to model the very specific shape of biological macromolecules. For such cases, Bloomfield et al. [3,4] designed the so-called bead models, in which the shape of a rigid particle is represented by an array of spherical elements. By using a sufficient number of beads of (possibly) varying size, the intricate details of macromolecular shape can be deduced. Two illustrative examples are displayed in Figure 1. The theory on which bead modelling is based comes from the pioneering works on macromolecular hydrodynamics by Kirkwood and Riseman [5,6], of which Bloomfield et al. adopted an approximate, simplified form. Garcia de la Torre, Bloomfield and co-workers improved the theoretical treatment and took advantage of the increasing availability of computing power, developing methods for efficient and accurate calculation of hydrodynamic properties of bead models of arbitrary complexity [7-131. A few years ago the computer program HYDRO was published [14] as a useful tool to calculate some hydrodynamic properties of bead models. It was soon evident that the utility of bead modelling could be pushed further in various directions. (1) Prediction of complex, more involved solution properties, usually related to rotational brownian diffusion of the rigid solute particles, that are monitored in some electrooptical and spectroscopic techniques. (2) Calculation of compound quantities involving two solution properties in such a way that the combination depends on the shape but not on the size of the particles. Such quantities had been


Eric Bentley's Brecht-Eisler Song Book. Katyn Levitt, soprano; Eric Ostling, piano; Larry Saltzman, guitar; William Schimmel, accordion. (Roven Records RR 62215; 56:00)"Ballad of the Soldier," "The Sprinkling of Gardens," "And What Did She Get?" "Song of the United Front," "To the Little Radio," "The Plum Tree," "The Love Market," "Song of the Moldau," "In the Flower Garden," "The Mask of Wickedness," "Easter Sunday, 1935," "The Son," "On Suicide," "On the World's Kindness," "Song of a German Mother," "A Saying (for 1935)," "Komintern," "Truly I live in a time of darkness!" "The Homecoming," "Solidarity Song," "You who will be borne up."Serious music and theater aficionados should know of the vast legacy of Bertold Brecht (1898-1956), one of the 20th century's most significant and influential playwrights, poets, and directors. Sadly, most Americans only know his name (if they know it at all) for The Threepenny Opera, the most noteworthy of Brecht's many collaborations with composer Kurt Weill. It's a brilliant work, but it does not begin to encompass the full scope of Brecht's extraordinary depth and breadth as a creative force.If Brecht is a somewhat obscure figure for the general public, composer Hanns Eisler (1898-1962) is wholly forgotten, and even some serious music students may not have encountered him in their studies. Eisler was the first student of Arnold Schoenberg to master his teacher's revolutionary twelvetone system, but almost immediately Eisler found his musical imagination taking wing in other directions, including jazz and cabaret music. When he moved to Berlin in 1925, he found himself immersed in one of Europe's leading centers for musical and theatrical innovation, and it was here that he and Brecht first met and began what would be decades of intermittent collaborations. By 1933, both Brecht and Eisler had fled the rising horror of Nazism and each eventually found his way to the United States. Eisler enjoyed success as a film composer and even earned Oscar nominations for two of his scores (Hangmen Also Die! and None but the Lonely Heart) before political troubles led to his deportation in 1948 to East Germany. It wasn't long before Brecht, disgusted by the poisonous political atmosphere created by Joseph McCarthy, willingly left this country and returned to his homeland. The two friends were able to collaborate on several occasions before Brecht's death in 1956. Eisler carried on after that as best he could, but the world of music was never the same without his dear friend in it, and his final years were quiet and shadowed with sorrow.The songs in this recording all come from The Brecht-Eisler Song Book that was published in 1967. The man most responsible for putting it together was British playwright and critic Eric Bentley, who is probably best known for his play The Life of the Drama. Singer Karyn Levitt's liner notes explain that Bentley had lived and worked in Los Angeles during the 1940s, which was how he met both Brecht and Eisler and began working with them. The specific impetus for the creation of the song book came after Bentley had a chance to thoroughly examine the ten (!) volumes of Eisler songs that were published under the auspices of the East German government. Levitt tells us that by singing through every song, Bentley came to a new appreciation for the composer's originality and also realized that at least some of them needed to be translated into English. Bentley was taking on an exceptionally tricky challenge, since Brecht's work was often replete with multiple meanings, and many of his texts had a distinctively tart tone that one would not want to be lost in translation. Bentley's efforts in this ambitious project were admirable, and if some of his translations are awkwardly clunky, others are remarkably seamless and true to their original precursors.As for the actual songs collected here, they will be an intriguing surprise for anyone who knows only the much more familiar Brecht settings of Kurt Weill, a far more mainstream composer than Eisler. …


Our research aims at providing a humanoid robot with the ability of observing, learning, and reproducing actions performed by humans in order to acquire new skills. In other words, we want to apply artificial intelligence techniques to automatically recognize a human activity in order to make a humanoid robot able to reproduce it.This system has not only to distinguish between different actions, but also to represent them in a proper manner to allow a robot to reproduce the motion trajectories the demonstrator showed and learn new skills. Since the final system is going to be integrated in an autonomous humanoid robot (specifically model Aldebran Nao), we are working with an RGB-D sensor (Microsoft Kinect) that can be easily applied to it. This objective introduces also strict real-time constrains to the action recognition algorithm: we have opted for a probabilistic approach that offers good modeling and fast recognition performances.


Bit synchronization in the presence of asymmetric channel noise has not appeared in the open literature. It is the purpose of this paper to study the tracking performance (clock jitter and cycle slip rate) of a popular digital clock synchronizer, the digital data transition tracking loop (DTTL), in the presence of asymmetric noise. Related parameters of interest, the transition density and data asymmetry, are also included. Acquisition performance (frequency acquisition time) is discussed in the absence of noise. A comparison of the DTTL and crossspectrum synchronization loop (CSSL) is also provided. Numerical results are Presented for the design of a bit synchronizer in this environment.


Clonal forestry has great potential advantages for increased genetic gains and crop uniformity. However, it has inherent risks, which must be managed appropriately. Those considered important to Pinus radiata D.Don clonal forestry include risks stemming from reduced genetic diversity through large-scale clonal propagation, and risks stemming from technical and logistical difficulties of clonal propagation and storage, and the evaluation of clonal material. The first category of risks is addressed in this paper; the second category, plus climatic risks, is addressed in the accompanying paper. The widely publicised risks of clonal forestry arise from the genetic uniformity of monoclonal crops and, on a broader scale, from potential restriction in total genetic diversity over clonal plantings. Both these factors are conducive to crop vulnerability to new and serious diseases, a prime hazard for P. radiata in New Zealand. The disease hazard, along with market risks, can be addressed by risk spread in numbers and genetic diversity of clones. This diversity can be achieved by either clonal mixtures or monoclonal mosaics, and must be addressed across landscapes and across age-classes. There are various approaches to quantitative modelling of the risks, to help devise risk-management strategies. Crop failure can be addressed in terms of probabilities. A generalised approach addresses probability distributions for adverse outcomes of varying severity. Less elaborate approaches involve standard errors (which can be applied to clonal under-performance), or the probability of any one clone failing disastrously. Ulterior risks of clonal forestry involve management of the genetic diversity that is needed for long-term breeding, as distinct from safe deployment of current crops. No restrictive regulations exist in New Zealand concerning use of clones, unlike the situation in various European countries, nor is there a local code of practice. Such a code may not only be prudent business, but may also maintain public confidence and forestall restrictive regulations.


The immunogenicity of DNA vaccine directly related to antigen gene expression and immunogenicity of antigen expression.In order to enhance the immunogenicity of DNA vaccine,the HA gene of H1 subtype Swine influenza virus was optimized according to the swine bias codon usages(optiHA).The optiHA and the wild-type HA gene were inserted into the PCAGGS vector,respectively,and then the two recombinant plasmids PCAGGS-optiHA and PCAGGS-HA were constructed.The HA protein transiently expressed in 293T cell was detected by indirect immunofluorescence at 48h post transfection.Each of six to eight week-old BALB/c mouse was inoculated by multi-point injection with 100 μg of plasmids PCAGGS-optiHA and PCAGGS-HA.The control group was injected with PCAGGS vector alone.A total of immunity were three times interval of two weeks.All mice were challenged with 103.87EID50 of A/Swine/Guangdong/1/01(H1N1) after two weeks of the third immunity.The immunogenicity of the two vaccines were evaluated by HA specific antibody production,HI antibody production,cytokines production and so on.The result showed that the DNA vaccine with encoding codon-optimized HA gene can significantly enhanced the expression of HA gene and improved the response level of humoral and cellular immune compared to the DNA vaccine with wild-type HA gene.In addition,the virus replication were inhibitated completely in the lungs of mice in the PCAGGS-optiHA vaccine group.These results might lay the foundation for the further study and design of the effective DNA vaccine of Swine influenza virus.


In August 2004, the American Academy of Nurse Practitioners (AANP) completed the 2004 AANP National Nurse Practitioner Sample Survey, with a 65-item instrument designed to collect data about nurse practitioners (NPs) and their practice characteristics. The project replicated two earlier studies conducted by AANP in 1989 and 1999, withminor adaptations relevant to contemporary practice. The project collected data on NP clinical specialization, educational background, patient populations, practice communities and settings, prescriptive practices, salaries and employment benefits, liability experiences, and other variables. This is the third article in a series describing the findings from this study and describes the relationship between NP income and several other variables, based on responses of the 16,062 NP respondents who were in active practice at the time of the survey. The first article in the series provided a more detailed discussion of the study methodology (Goolsby, 2005). However, the target sample was stratified to represent the NP population by specialty and included 23,850 NPs, or approximately 25% of the NP population at the time. The over 16,000 respondents represented approximately 17% of the NP population and are characteristic of the overall population.


Dannenhauer, Zohreh A. Ph.D., Computer Science and Engineering Department, Wright State University, 2019. Anticipation in Dynamic Environments: Deciding What to Monitor. In dynamic environments, external changes may occur that may affect planning decisions and goal choices. We claim that an intelligent agent should actively watch for what can go wrong and anticipate changes in the environment that allows the changing of its plan or changing of a given goal. In this thesis, we focus on the relationship between perception, act, interpretation and planning. We claim that these components are not independent and need to interact with each other to help the agent succeed in achieving its goals and plans. If newly encountered world information affects the plan, the agent adapts to it through the refinement of plans under construction. If the justification for goal selection changes, then the agent should transform or abandon the goal. Our approach is to make perception sensitive to relevant changes in the environment that can affect plans and goals. We will present results with a cognitive architecture in different domains such as blocksworld, logistics, minecraft and a Baxter humanoid robot to show the effectiveness of the proposed approach.

Nanocrystalline Fe2TeO6 (FTO) is synthesized following the sol-gel process. The nanoaspect of FTO is confirmed from transmission electron microscopy, where the particles of sizes 10–40 nm are seen. Magnetic measurement on nano-FTO confirms the antiferromagnetic nature of particles having Neel temperature TN = 167 K, which is very much lower than that of bulk (210 K). Polarization verses electric field loop measurement at room temperature (RT) gives the remanent polarization (Pr) value of 0.098 μC/cm2, confirming ferroelectricity in FTO. A nonmonotonous increase in the remanent polarization is noticed when an external magnetic field is applied on the sample. This is a clear indication of prevailing substantial magnetoelectric (ME) coupling in the sample at room temperature. The quantification of magnetoelectricity is done by directly measuring the ME voltage (V) in the presence of varying dc magnetic field (H), and the ME coefficients are obtained using a quadratic relation in H. The values so obtained for the first order (α/d), second order (β/d), and third order (γ/d) ME coefficients are ∼0.22 mV cm−1Oe−1, ∼−1.70 × 10−2 mV cm−1 Oe−2, and ∼0.72 × 10−6 mV cm−1 Oe−3, respectively. The presence of ferroelectricity and magnetoelectricity above the Neel temperature is a very unusual phenomenon in this material. The presence of short range magnetic ordering which prevails even up to RT, much higher than that of long range magnetic ordering temperature, is suspected to be responsible for this.Nanocrystalline Fe2TeO6 (FTO) is synthesized following the sol-gel process.

This case study describes the problems faced and remedial efforts taken by FBSB, a private medical clinic to address its high staff turnover rate. In order to compete in a highly competitive environment, FPSB needs committed, trained nurses to provide effective levels of patient care. However, due to the high staff turnover rate, staffing and patient contact time is reduced, consequentially resulting in lower productivity level due to loss of experienced staff and undermined teamwork. FPSB also incurred higher staff costs as they needed to recruit, educate and train new staff. This case was identified as a result of declining sales growth and profits, patient complaints, and increase in staff costs in FPSB. The data related to this case study was compiled from the interviews conducted with key personnel of the company, review of the company's periodic Financial Statements and exit interview data, and also through observations of the staffs' daily routine on the job. The analysis on the information gathered is based on proven management concepts and theories in the areas of employee turnover, and factors that contribute to the phenomenon. The steps to mitigate the problems and the solutions are identified through the changes made in the company through strategic interventions. The outcomes of each of those strategic interventions are recorded in this case study in order to provide further understanding on the nature of problem and remedial actions for future application.


A dog, just like a human, has the ability to feel many emotions directly related to a given sit- uation. Out of all the emotions a dog experiences, fear is the one that causes unpredictable behaviour. The undisputed source of stress for a dog may be a visit to a veterinary office and related medical procedures, separation from the owner, but also pheromones left by other animals. The aim of this study was to determine the dog's stress level in a veterinary office depending on its age. The material was collected by an electronic survey in February 2021 among 381 dog owners. The analysis of the results concerning the dog's behaviour was carried out according to the age groups of dogs and the five-point scale of answers. In the second part of the study, the occurrence of certain dog behaviours was checked depending on the owner's stress level. The final stage of the research was the use of selected music as a factor reducing stress in dogs and observation of their behaviour (in January and February 2022). The most common stress behaviours reported by the owners were: lowered body posture, tail tuck, retracted ears, and trying to escape, nose licking. Our own research proved that the calmer the owner is, the lower the frequency of stress reactions in the dog. It was found that dogs exposed to calming music while waiting in the waiting room for an appointment showed fewer stress reactions than dogs waiting in the waiting room without music.


The Design Of Alternative Power Plant By Using Flywheel includes testing when the electric motor as the driving force that drives the flywheel and ac synchronous generator with no load and load installed in the form of an incandescent lamp has a power of 100 watts to 1000 watts. This was done to compare the results obtained by the residual voltage ac generator when the motor as the prime mover is turned off. The residual stress is obtained due to the influence of the flywheel which has a fairly heavy mass. Further testing the ability of the electric motor as the driving that drives the flywheel and ac synchronous generator when the generator 100 watt ac saddled up to 1000 watts, while the capacity of only 370 watt electric motor and T (torque) maximum 2.5 Nm. Flywheel role is to help the rotation so that the electric motor is able to drive the ac generator with loads up to 1000 watts. When a load of 400 W, obtained torque of 2.7 Nm. It can be seen that the current load of 400 W has a torque in excess of the maximum torque capacity owned motorcycles. Similarly, further, when a load of 500 W until 1000 W, the greater the torque obtained. Keywords: alternative power plant, flywheel, ac generator, electric motor,

Extracting matched details of the PANchromatic (PAN) image and injecting them into the MultiSpectral (MS) images, is very crucial in pansharpening. In this paper, a new pansharpening method based on Joint Local Low Rank Decomposition (JLLRD) and Hierarchical Geometric Filtering (HGF) is proposed. First, a cascaded geometric filtering is performed on the PAN and MS images, to extract their multi-scale directional details. Then a joint local low rank decomposition is developed to deduce low-rank and sparse components for injection. Finally, an adaptive injection rule based on spectral correlation coefficient, is designed to further reduce spectral distortion of the fused images. Several experiments are taken to investigate the performance of the proposed JLLRD-HGF method, and the results show that it can extract more accurate injection details and produce less spectral and spatial distortions than its counterparts.


The authors evaluated the effect that gear oil viscosity and additive composition have on pitting damage by using an adjustable-quality process gear. The results indicate that for oils with the same additive composition, high-viscosity gear oils are more effective for preventing pitting damage; that the effectiveness of high-viscosity oils is shown to be the same even if their additive composition is different; and that for oils with identical viscosities, pitting occurs most easily in the order of SP-Mo, SP, and Zn additives. These facts conform with the tendency for pitting resistance to be higher the smaller the coefficient of friction at the contact surface where rolling and sliding occur together, and lubricating oils that keep tangential force on the tooth surface small are understood to be beneficial at preventing pitting. The occurrence of pitting causes gear system vibration to increase, but in the FZG gear tester used here, when the surface area ratio of pitting occurrence reached 3% or more, the acceleration of vibration became greater, so the importance of making such an evaluation after selecting a pitting occurrence surface area ratio appropriate to the test system was made clear. It was also clarified that a step-up load test method could evaluate the anti-pitting properties of a lubricating oil in only about a tenth of the time needed with previous methods using a set load.

The goal of this paper was to understand if the current KM practices in a consultancy organization met what the workers preferred and in what way ethnography could be integrated in these practices and give guidelines for future studies where it can be integrated in the talent management process. The results showed an organization with employees willing to share their knowledge and obtain it through methods that involve the participative observation employed in ethnography as in the Socialization process of the SECI Model.


The limiting of water resource and traditional farming practices are threatening the sustainability of important minor crops in Pakistan, including berseem, which is a key source of fodder for dairy farms. Each year, 2% reduction of cultivated area, low yield and grower's non-preference (to rotate or replace wheat-cotton pattern) factors are adversely affecting the livestock sector. Consequently, animal rearing business is suffering badly due to lack of fresh forage in the country. Therefore, a three-replicated randomized complete block design (RCBD) field experiment was conducted during rabi season to evaluate berseem crop in term of yield and profit under existing farming practice (85:115:00 NPK kg ha − 1 + 12 irrigations with 15 days intervals) and optimized treatments (70:100:30 NPK kg ha − 1 , 55:85:15 NPK kg ha − 1 + 12, 08, 04 irrigations + 15, 18, 21 days intervals). The net plot size was 12 m 2 with a pH range of 8.1 silty clay loam soil type. In addition, the climate was monitored as well, there was no rainfall observed during the entire crop period. The analysis of statistical data showed a significant (p − 1 , branches plant − 1 , plant weight, fodder and seed yield, net profit, and profit on $ − 1 (81.8 cm, 100.8, 36.0, 19.3 (g), 72.0 t, 829.30 kg ha − 1 , $1910.8 ha − 1 , $2.03 respectably) were measured from treatment 70:100:30 NPK kg ha − 1 + 12 irrigations at 15 days intervals, which is recommended to the farmers of synonymic agro-environmental conditions. Furthermore, the treatment 70:100:30 NPK kg ha − 1 + 8 irrigations was also better with the aspect of satisfactory outcome and 33% less use of water.

The purpose of this study was to assess the participation of preparatory secondary school teachers in action research and to explore factors that hinder the realization of action research in schools. Descriptive survey design was employed as a method of research. Open and closed ended questionnaire, focused group discussion and individual interview were used as instruments to collect the data. The data was collected from six schools. Teachers and school principals were participated as subject of the study. The data gathered through closed ended questionnaire was analyzed using percentage. Whereas from open ended questionnaire, focused group discussion and interview was analyzed in the form of quotation and narration. The findings revealed that understanding of preparatory secondary school teachers' about action research was at the lower level. School principals who are expected to provide professional support for teachers had no detail awareness and skill about action research. Engagement of teachers in action research activities had been hindered by lack of training and experience on how to conduct action research, lack of support and monitoring, work over load and shortage of time, lack of incentives, lack of research facilities and less attention given for action research. Thus, it is critically important to organize short term training and experience sharing; establishing well equipped libraries; enhancing the support and follow-up system; establish rewarding mechanism as possible solutions to be taken into account for improving the participation of teachers in action research. Keywords: Action research, preparatory secondary school, school principals, West Gojjam.


Estimations of scale effects on blade cavitation require consideration of multiple models for both water flows and cavities. In particular, distinction of laminar and turbulent boundary layers is very important. A qualitative impact of selection of models is manifested for blade sheet cavitation. Its quantitative impact is shown for vortex cavitation inception.


The proposed research investigates how designers use heuristics, or cognitive strategies, to identify specific solutions in a "trial and error" creative process, and how team collaboration may use multiple heuristics across team members as a means to generate robust designs; that is, designs that remain successful despite variability in consumer preferences, both over people and time. The intent of this study is to understand the cognitive heuristics that support creative, innovative, and robust designs. Heuristics are reasoning processes that do not guarantee the best solution, but often lead to potential solutions by providing a "short-cut" within cognitive processing [8]. It is proposed that designers utilize specific design heuristics to explore the problem space of potential designs, leading to the generation of creative solutions. Further, these design heuristics can be taught, and their use will facilitate design at multiple levels of instruction.


Many forms of wireless connectivity such as Wi-Fi, cellular data, Zig bee, etc. exist in the fastest growing domain of wireless technology. However, one of the most important and popularly used wireless protocols is Bluetooth, which was originally designed for the solution of the wired mode of data transfer (RS232, UART). Indoor localization technology based on the latest avatar of Bluetooth protocols viz Bluetooth Low Energy (BLE) is used to address the inadequacies of global positioning systems in indoors such as buildings, offices, houses, etc. since people use to spend the majority of their time there. The use of BLE becomes significant as it is a power-efficient and low-cost technique. It provides 40 channels of 2MHz Bandwidth each with 3 advertising channels and 37 channels for data transfer. In this paper, a parameter based on the received signal power viz. The RSSI value is proposed to be used for efficient indoor localization applications using BLE technology. The problem of non-static values of RSSI due to its dependence on the surrounding environment is proposed to be overcome in this paper by stabilizing the received power using mean and median filters. The localization accuracy is enhanced through static values of RSSI obtained using both these filters.

Objective To quantitatively detect the O6-methylguanine-DNA-methyltransferase( MGMT) methylation levels in tumor tissue and peripheral blood of colorectal cancer patients by methylation-sensitive high-resolution melting( MS-HRM) analysis,and evaluate its clinical significance based on pathological parameters. Methods The MGMT methylation levels in tumor tissues and corresponding normal mucous membrane tissues from 33 patients with colorectal canser and in peripheral blood samples from 16 patients were determined by MS-HRM. The relationship between MGMT methylation levels and the clinical-pathological features of colorectal cancer were analyzed and the detection performance of the MS-HRM was evaluated. Results The methylation of MGMT promoter region was detected in 36. 4%( 12 /33) of tumor tissue samples,including 1 with 5% of methylation,3 with 5%-10%,3 with 10%-25%,2 with 25%-50%,and 3 with 50%-75%,while 3. 0%( 1 /33) of normal mucous membrane tissue and 18. 8%( 3 /16) of peripheral blood samples with 5% of methylation. The MGMT methylation levels were not related to patients' age,gender and tumor location( P 0. 05),but significantly related to the pathological stage and differentiation of colorectal cancer( P 0. 05). Conclusion The MS-HRM method may be used to quantitatively detect the MGMT methylation levels in the patients with colorectal cancer,and the MGMT methylation may be related to the progression of colorectal cancer.

The level of intraday liquidity needed for settlement varies according to settlement methods. This paper is an empirical study based on funds transfer data in Japan of the effects of the shift from deferred net settlement (DNS) to real time gross settlement (RTGS) with liquidity-saving features (LSF) on the liquidity for settlements of payments among financial institutions. The study has revealed the following: (1) The extent to which liquidity financial institutions put into their accounts for settlement has increased due to the shift to RTGS; (2) the level of the liquidity which was not used for settlements; (3) the liquidity-saving effects of the LSF in an accommodative monetary environment under the zero-interest rate policy; (4) the extent to which the liquidity-saving effects have increased by the uniform application of LSF to different types of transactions; and (5) the extent to which the collateral requirements have declined as a result of the reduction in transactions settled on a DNS basis.


Au-Ag alloy films of 50 nm thickness were sputtered on the glass substrates for the first application as a wavelength-interrogated near infrared surface plasmon resonance (SPR) sensor. By using a series of aqueous glucose solutions as the standard refractive-index (RI) samples, the RI sensitivities of the Au-Ag alloy film based SPR sensor were investigated at different incident angles and compared with those obtained with a pure Au film. The experimental results indicate that a smaller angle leads to a larger initial resonance wavelength and a higher RI sensitivity and that the RI sensitivity with the Au-Ag alloy film is larger than that with the pure Au film in the case of the same resonance wavelength. The RI sensitivity with the Au-Ag alloy film was measured to be 35648.3 nm/RIU at θ = 7.5o, being 3.8 times as high as that obtained at θ = 9.5o. Responses to protein adsorption of the Au-Ag alloy film and pure Au film based SPR sensors were respectively investigated using a 1 μmol/L aqueous BSA solution. With the Au-Ag alloy film, the SPR response is ??R = 12.1 nm, higher than ??R = 9.5 nm obtained with the pure Au film. The experimental results also indicate that the Au-Ag alloy film based SPR sensor has a broader resonance band and thus a lower spectral resolution than that based on the pure Au film at the same resonance wavelength.

Phase mixing has been a popular theoretical mechanism invoked to dissipate the photospheric plane shear Alfven waves hypothesized to penetrate up into the coronal hole and solar wind, thereby maintaining the expanding coronal gas at 1.5 million K and serving as the principal energy source for the solar wind. However, phase mixing requires an ignorable coordinate, which is not available in the presumably filamentary coronal hole. The filamentary density and temperature of the coronal hole couple the waves into a coordinated mode with a unique phase velocity omega/k, which provides the other popular theoretical mechanism, viz, resonant absorption where the local Alfven speed C is equal to omega/k. This provides coronal heating at radial distances O(10 solar radii), where it serves to accelerate the solar wind to high velocity. But it does not provide the principal heat input in the first 1-2 solar radii, required by Withbroe's (1988) analysis of the observed structure of the coronal hole. 41 refs.

Abstract The electrochemical noise of a primary lithium battery was measured at an open circuit by two experimental approaches: with a filtering capacitor and with the same battery to eliminate open circuit voltage of the system under test. Both methodologies give the same results if they are applied correctly but they can sometimes cause experimental problems. Two experiments were carried out with battery discharge at resistive load. It was shown that it is very difficult to provide the conditions for properly operation of the two battery method to avoid saturation of measurement device when the amplifier uses high gain values.


Beyond the aggravating effects of climate change on both sedentary agrarian farming communities and the pastoral herders, are other man made factors, which could be seen in the persistent occurrence of farmers-herders conflicts in Benue State and across various parts of Nigeria, thus a clog in the wheel of progress to national development and cohesion. It was against this background that this study engaged conflict theory to examine the factors responsible for farmers-herders conflict in Benue State. The study employed Taro Yamane sampling technique on administered five-Likert scale questionnaire. Findings from study on the factors responsible for farmers-herders conflict reveals that encroachment on farm lands and crop destruction by cattle stands at (71.1%), Unemployment and poverty (62.9%),Communication barrier/Mutual distrust (64.2%), inadequate grazing reserves/Blockage of grazing routes (68.4%,), Raping/Kidnapping of women (59.4%), Land ownership tussle/ Indigenization (51.6%), Cattle rustling/Theft (26.6%) and Contamination of river bodies by cattle (71.9%). The deduction therefore is that majority of the respondents emphatically agreed with all the factors mentioned above as the major causes of the conflict in Benue and Nigeria in general. However, the opinions of most respondents out rightly rejected cattle rustling as a major cause of the conflict in the study area. The study recommends that the establishment of modern functional cattle ranches will significantly address the issues of grazing routes blockage and encroachment on farm lands/crop destruction which will drastically reduce or completely eliminate farmers-herders conflict in Nigeria. This study also recommends the urgent implementation of the National Young Farmers Scheme' aimed engaging modern methods of farming by engaging 1,000 farmers from each of the 774 Local Government. That Federal government should evolve genuine and workable national strategies of disarming the armed killer herdsmen parading farming communities in Benue with sophisticated weapons of Ak47 to commit carnage, and rape against farming communities.


Goals are results of pin-point shots and it is a pivotal decision in soccer when, how and where to shoot. The main contribution of this study is two-fold. At first, after showing that there exists high spatial correlation in the data of shots across games, we introduce a spatial process in the error structure to model the probability of conversion from a shot depending on positional and situational covariates. The model is developed using a full Bayesian framework. Secondly, based on the proposed model, we define two new measures that can appropriately quantify the impact of an individual in soccer, by evaluating the positioning senses and shooting abilities of the players. As a practical application, the method is implemented on Major League Soccer data from 2016/17 season.
