Log files (discrete recordings of user actions during software use) offer the ability to collect human-computer interaction data on a number of users, over time, while the users are engaged in typical tasks in typical environments. The disadvantage of log files is the lack of automated methods for analyzing the volumes of data in a meaningful way. This paper presents a log file analysis tool, Hawk, and discusses the characteristics which make it useful for this task. A particular analysis technique, based on Markov chain analysis, is described which can be used to derive high-level software usage patterns. A study of student interactions with a programming environment are used for examples of the use of the the tool and the technique. Log files (that is, discrete recording of user actions during software use) have several characteristics which make them ideal for research on the design of user interfaces and on the interactions between humans and computers. They can be used to collect data on any number of users over time, during each and every use of the software. Particularly important is that log files can be used to collect data while users are working on typical tasks in typical environments. More traditional methods for gathering data on human-computer interactions, such as think-aloud protocols, require unusual settings that can confound the analyses. The disadvantage of log file data is that there are few analysis techniques. Log file data tends to be voluminous, and often at too low a level to be of much use without some aggregation (e.g., individual keystrokes), suggesting the need for automated analyses. Researchers in hypertext and hypermedia have developed techniques and tools for using log files to trace access and then to develop an assessment of student concept formation in terms of information accessed (e.g., Log file analysis techniques for exploring user interactions with other forms of software are more rare. Hammer and Rouse (1979) used Markov chain analysis (a standard analysis tool, to study keystrokes in editing text files, but found the technique to be too sensitive to individual differences. Winne and Gupta (1993) have identified a number of powerful measures to use in evaluating log files of students using a computer-based study aid. The techniques of Winne and Gupta are based on data and graph theory, and they


The presented study demonstrates a bi-sensor approach suitable for rapid and precise up-to-date mapping of forest canopy gaps for the larger spatial extent. The approach makes use of Unmanned Aerial Vehicle (UAV) red, green and blue (RGB) images on smaller areas for highly precise forest canopy mask creation. Sentinel-2 was used as a scaling platform for transferring information from the UAV to a wider spatial extent. Various approaches to an improvement in the predictive performance were examined: (I) the highest R2 of the single satellite index was 0.57, (II) the highest R2 using multiple features obtained from the single-date, S-2 image was 0.624, and (III) the highest R2 on the multitemporal set of S-2 images was 0.697. Satellite indices such as Atmospherically Resistant Vegetation Index (ARVI), Infrared Percentage Vegetation Index (IPVI), Normalized Difference Index (NDI45), Pigment-Specific Simple Ratio Index (PSSRa), Modified Chlorophyll Absorption Ratio Index (MCARI), Color Index (CI), Redness Index (RI), and Normalized Difference Turbidity Index (NDTI) were the dominant predictors in most of the Machine Learning (ML) algorithms. The more complex ML algorithms such as the Support Vector Machines (SVM), Random Forest (RF), Stochastic Gradient Boosting (GBM), Extreme Gradient Boosting (XGBoost), and Catboost that provided the best performance on the training set exhibited weaker generalization capabilities. Therefore, a simpler and more robust Elastic Net (ENET) algorithm was chosen for the final map creation.

In EEG/MEG source analysis, a mathematical dipole is widely used as the "atomic" structure of the primary current distribution. When using realistic finite element models for the forward problem, the current dipole introduces a singularity on the right-hand side of the governing differential equation that has to be treated specifically. We evaluated and compared three different numerical approaches, a subtraction method, a direct approach using partial integration and a direct approach using the principle of Saint Venant. Evaluation and comparison were carried out in a four-layer sphere model using quasi-analytical formulas.


This paper presents a redundant flash ADC using a "Split-ADC" calibration structure and lookup-table-based correction. ADC input capacitance is minimized through use of small, power efficient comparators; redundancy is used to tolerate the resulting large offset voltages. Correction of errors and estimation of calibration parameters are performed in the background in the digital domain. This 5.8 ENOB flash ADC is designed for a sampling rate of 1Gs/s in 45nm SOI CMOS.


A new wavelength-division-multiplexed (WDM) access passive optical network (PON) architecture was demonstrated using a sequentially pulsed multifrequency laser source that was distributed to support 144 PONs each having eight 53-Mb/s WDM downstream channels. The architecture is scalable to larger numbers of PON's and channels and higher data rates.


Pseudomonas fluorescence hw-5 strain isolated from the rhizosphere soil was used to control Gaeumannomyces graminis by the methods of seed coating,seed soaking and soil drench.The results show that the seeds treated by the three methods have a stronger resistance to the take-all of wheat in seedling.


Using incubation experiments with size-fractionated coastal waters, this study calculated the growth and loss rates of nanoflagellates in a coastal ecosystem of the subtropical western Pacific along a rocky shore in northeastern Taiwan. Samples were taken monthly from September 2014 to August 2015. Seasonal variations in growth rates of heterotrophic nanoflagellates (HNF) and pigmented nanoflagellates (PNF) ranged from 0.17 to 1.13 d and 0.05 to 1.21 d, respectively. This study found that grazing had a significant impact on nanoflagellate community (PNF: 0.14 to 0.39 d; HNF: 0.12 to 0.52 d), accounting for about 15-30% for PNF and 18-60% for HNF growth during the warmer periods. However, during colder period, grazing was not found to have an impact on the mortality of nanoflagellates in this subtropical coastal ecosystem. Furthermore, an interesting phenomenon in this study, composition of nanoflagellates 5-10 m and > 10 m size class showed a more pronounced increase in < 20 m treatments at the end of experiments during the warmer study periods. We suggest that at least two trophic levels within the nanoflagellate community: small nanoflagellates and large nanoflagellates.


gastrointestinal contrast study showed absence of contrast opacification beyond punctate gastric hemorrhages, and near complete gastric outlet obstruction (GO A 2-year-old boy presented with 1 week of postprandial nonbilious emesis, with onset 9 days after ingesting Lysol toilet cleaner (9.5% hydrochloric acid). An upper the pylorus. An esophagogastroduodenoscopy revealed a dilated dysmotile stomach, O) at the pylorus (Fig. 1A), through which a nasojejunal tube was passed using an over-the-wire technique (Fig. 2) to provide nutrition. The esophagus was entirely normal. Serial fluoroscopic balloon dilations (FBDs) with endoscopic visualization (Fig. 3) were performed at weeks 5, 8, and 10 to 10, 12, and 14 mm, respectively. At week 16, the pylorus opened nicely (Fig. 1B) and the patient tolerated a soft diet.


The Greater Mekong Sub-region (GMS) consists of Thailand, China, Vietnam, Laos, Myanmar and Cambodia. These countries have turned to be important Para rubber raw materials exporters. There have been some business transactions carried out by the Chinese traders from the mainland China, e.g., the policy on expansion of a project viz. East West Economic Corridor (EWEC) where various Chinese traders have participated with many business engagements, particularly the investment concerning production of raw materials derived from Para rubber trees. The objective of this paper was to point out newly established regional areas of Para rubber producers that have relatively turned out to be the important producers of raw materials derived from Para rubber trees. Some of them could become rivals in trading against the Thai traders in the near future. Also, the paper gives some important viewpoints on cultivation of the crop when Thailand hasn't been well equipped with analytical data on the improvement policy upon Para rubber production. If rival countries offer competitive price, it could be the case that Thailand misses out its opportunity to share the market as a business partner in the region. Thus, Thailand may lose its leading role as one of the biggest world exporters of Para rubber raw materials, and unable to formulate trade direction on prices of the products. It was found that within this decade, Chinese traders had been involved in overseas business on the establishment of Para rubber plantations, e.g., in Laos and Cambodia where they had rapidly increased land areas for Para rubber plantations. Nowadays, China is the biggest importer of Para rubber raw materials in the world due to the rapid expansion of automotive industries. In the past, Thailand, Indonesia, and Malaysia used to be the world leading suppliers of Para rubber raw materials up to 3,922.8 tons or about 39.22 % of total production of the world between the years of 2002 and 2008, which was lesser than a decade later. The countries in the GMS were able to produce Para rubber raw materials up to 5,844 tons or about 58.44 % of the world production, particularly Vietnam, where exportation increased most rapidly compared to other exporters. In 2005, Vietnam was ranked the fourth in exporting Para rubber raw materials to China. Some important advices in cultivating the crop are recommended.


We report the quenching of Yb3+ luminescence observed in Yb:YAG and Ni(0,1%):YbAG crystals. Yb2+-ions and impurity ions of nickel coming from the crucible during crystal growth were determined as efficient quenching centers in Yb:YAG crystals grown by the Czochralski-method. As an indicator of the quenching process we measured the fluorescence lifetime of the investigated crystals and its dependence on the excitation power. The theoretical models for the energy transfer processes to Yb2+- and Ni2+-ions are presented. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)


However, public resources are limited and must be used efficiently, based on a strategic assessment of needs and priorities. Preventing the loss of existing public goods should have priority in the impact assessment. This means as a starting point identifying the EU farming types and situations that are inherently most valuable in terms of public goods, and assessing whether policies are designed in a way that ensures their maintenance.


Educational visionaries and reformers have long predicted a significant transformation of teaching and learning that would be facilitated by technology, essentially providing every learner with the equivalent of a personal tutor. Technology implementations in education, however, have consistently fallen short of achieving these lofty aims. The authors argue that this failure stems from a penchant to implement technology in ways that automate that past. Instead, we must champion learning technologies that are learner-centric and malleable, such that they address the needs of individual learners and can take advantage of the power of network effects. Only then will we realize the long-awaited transformation


The tolerance of transplanted lanceleaf coreopsis (Coreopsis lanceolata L.), ox-eye daisy (Chrysanthemum leucantheum L.), purple cone flower (Echinacea purpurea (L.) Moench.), and blanket flower (Gaillardia aristata Pursh) to metolachlor was deter- mined in field trials. Metolachlor at 4.5 kg·ha -1 (maximum use rate) and 9.0 kg·ha -1 (twice the maximum use rate) did not reduce stand or flowering of any wildflower species after one or two applications, although plants developed transient visible injury. Combining metolachlor with the broadleaf herbicides simazine or isoxaben resulted in unacceptable injury and stand reduction, especially in ox-eye daisy. Metolachlor plus oxadiazon was less injurious to the wildflowers than metolachlor plus either simazine or isoxaben. Treat- ments containing metolachlor controlled yellow nutsedge (Cyperus esculentus L.) by at least 89% in both experiments. Treatments containing isoxaben controlled eclipta (Eclipta alba L.). 100% in both studies. Chemical names used: N- (3-(1-ethyl-1-methylpropyl)-5- isoxazolyl)-2,6-dimethoxybenzamide (isoxaben); 2-chloro -N- (2-ethyl-6-methylphenyl) -N- (2-methoxy-1-methylethyl)acetamide (metolachlor) ; 3-(2,4-di-chlo ro-5-(1- methylethoxy)phenyl)-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2-(3 H) -one (oxadiazon); 6-chloro -N,N' -diethyl-1,3,5-triazine-2,4-diamine (simazine).


Crystallization of the lunar magma ocean creates a chemically stratified Moon consisting of an anorthositic crust and magma ocean cumulates overlying the primitive lunar interior. Within the magma ocean cumulates the last liquids to crystallize form dense, ilmenite-rich cumulates that contain high concentrations of incompatible radioactive elements. The underlying olivine-onhopyroxene cumulates are also stratified with later crystallized, denser, more Fe-rich compositions at the top. This paper explores the chemical and thermal consequences of an internal evolution model accounting for the possible role of these sources of chemical buoyancy. Rayleigh-Taylor instability causes the dense ilmenite-rich cumulate layer and underlying Fe-dch cumulates to


Results: The study revealed that 26 (27.7%) patients had normal cognitive function, 32 (43%) had mild cognitive impairment, 21 (23%) had mild dementia, 8 (8.5%) had moderate dementia and 7 (7.4%) had severe dementia. Older age, low education level and longer duration of dialysis history were found to have significant associations with cognitive impairment, [P: < 0.001, 0.002, and 0.012 respectively]. While hemoglobin, serum albumin, serum creatinine, serum urea, serum potassium and Kt/V showed no significant association with cognitive impairment, Serum sodium and dry weight dialysis showed significant difference between patients with normal cognitive function and patients with cognitive impairment, [P <0.001 both]. Conclusion: Cognitive impairment is prevalent in Egyptian older adults on HD and more prevalent and severe in those with older age, low education, lower level of serum sodium, longer duration of dialysis history and higher dry weight.


Significance The study of visual pigments (rhodopsin in rods and cone opsins in cones) in vision has a long and illustrious history. It is well established that rhodopsin is required for rod phototransduction, outer segment formation, and rod viability. It is not known if the same is true for the cones. By using the cone opsin–deficient mice, we made the surprising observation that cones survive for at least 12 mo without cone opsins, suggesting that cone opsins are dispensable for cone viability. Furthermore, cone opsin–deficient cones continue to mediate visual signaling by relaying the rod signal through rod–cone gap junctions. Our finding represents a major difference between the two types of photoreceptors in vertebrates: rods and cones.


The development of good material models, accurate nonlinear finite element codes, and computer-controlled presses make practical the application of control techniques to metal forging. This paper considers the open-loop problem of selecting a nominal ram velocity profile to produce a desired microstructure, given a specified die and preform geometry and forging temperature. Two approaches for doing so are applied to a simple, but representative problem. The first is based on classical numerical optimization techniques. The second is based on inverse neural networks and offers potential savings in critical computations. Simulation studies for the two methods show good results. >

The ongoing global climate change and the associated environmental degradation pose a threat to Europe and the rest of the world. Raw materials and energy are required to produce building materials, which are used for construction purposes. Resulting buildings and structures generate waste during construction, operation, and demolition, and they emit potentially harmful substances. Thus, the key to achieving climate goals is to support low-emission materials and technologies in the construction sector, significantly impacting the environment. In the European Union, building materials are not yet subject to mandatory sustainability assessment during the assessment and verification of constancy of performance (AVCP). Objective evaluation of construction materials' environmental impact requires it to be carried out based on production data on an industrial scale. This article presents the environmental impact of premixed gypsum-based plasters, commonly used in modern construction. Nine environmental indicators (global warming potential (GWP), depletion potential of the stratospheric ozone layer (ODP), acidification potential (AP), eutrophication potential (EP), formation potential of tropospheric ozone (POCP), abiotic depletion potential (ADP)-elements, ADP-fossil fuels, renewable primary energy resources (PERT), and nonrenewable primary energy resources (PERNT)) of premixed gypsum plasters based on natural and flue gas desulfurization (FGD) gypsum were estimated and discussed. Knowledge of the construction products' environmental impact is fundamental for creating reliable databases. AVCP of construction materials in the future will use the data collected during the voluntary environmental impact evaluation.


We present a silicon carbide (SiC) based surface micromachined nanoreactor for in-situ characterization of reactions between solid nanostructured materials and gasses in transmission electron microscopes (TEMs). For the first time SiC is used as construction material for this device and a novel design of gas-microchannel with a two-level height is implemented. The use of SiC compared to the standard construction materials allows for easier and more reliable fabrication of the complete microsystem and for improved performance in terms of temperature. Additionally, the two-level height channel eases the loading of the specimens without affecting the sensitivity in the gas analysis.


Specific surface area (SSA) values for Fe–smectite alone and mixtures comprising varying proportions of glacial till were determined by nitrogen-adsorption Brunauer–Emmett–Teller analysis under different outgassing temperatures. Additionally, the extent to which the SSA of a mixture was related to the SSA of its components was investigated. A theoretical value for mixture SSA can be computed by summing the products of component SSA and the corresponding weight fraction. This theoretical estimate may not always yield the same value as measured because of a variety of physical and chemical interactions that can lead to either aggregation or dispersion of the constituent matrix. The results are explained in terms of these interactions and within the context of SSA relevance to barrier performance. For mixtures comprising 90% glacial till and 10% Fe–smectite, measured specific surface areas were consistently higher than predicted values for outgassing temperatures beyond 100°C, with a maximum departure of 4 m...


We show that all sufficiently nice λ-sets are countable dense homogeneous (CDH). From this fact we conclude that for every uncountable cardinal κ ≤ b there is a countable dense homogeneous metric space of size κ. Moreover, the existence of a meager in itself countable dense homogeneous metric space of size κ is equivalent to the existence of a λ-set of size κ. On the other hand, it is consistent with the continuum arbitrarily large that every CDH metric space has size either ω1 or c. An example of a Baire CDH metric space which is not completely metrizable is presented. Finally, answering a question of Arhangel'skii and van Mill we show that that there is a compact non-metrizable CDH space in ZFC.


This paper studies the Chinese Postman Problem with Time Dependent Travel Times. This problem is motivated by hybrid system testing where the ``timing'' of each transition is crucial. We give a new formulation to the problem as a set covering problem with partial order, whose linear relaxation can be solved tractably by column generation. Feasible columns are added by solving the minimal successor(predecessor) circuit sub problems with genetic algorithms. Computational results on the medium-sized instances with random time dependent travel times are reported, which show that the gap associated with the upper bound and the relaxation bound obtained by the column generation algorithm is almost less than 5.98%.


1. MODEL FOR PHOTON EFFICIENCY A mathematical model has been constructed to analyze the photon efficiency of frequencydomain fluorescent lifetime imaging microscope (FLIM) systems [1,2]. As shown in Equations 1 and 2, the power of the light source needed and the signal to noise ratio (SNR) expected at the detector can be calculated. Figure 1 shows the model at the system level. The SNR analysis assumes Poisson noise and has been validated in experiments. Moreover, experiments using samples in differing concentrations have been carried out to validate other aspects of the model.


Electrosurgery unit has the purpose of damaging certain body tissues by heating the tissue.  In this study there are several modes and also power selection. The contribution of this research is to design the power management and also the addition of several modes for the surgical process. Electrosurgery Unit involves the use of IC CMOS 4069 as a frequency generator. The frequency output is set at 250 KHz and then passed on to the pulse regulator circuit and controlled by using Arduino and then forwarded to the inverter circuit which functions to increase the voltage and output in the form of power. Modules are calibrated using ESU Analyzer. This module is equipped with a selection of LOW, MEDIUM, and HIGH power. And also there are some additional modes including Blend 1 and Blend 2. After the measurement is carried out, the voltage values obtained at the setting of low, medium high, on the inverter input with a value on Blend 1 mode low 80 V with an error of 0.84%, Medium 90 V with error 0.84%, High 104 V with an error of 0.81%, in Blend 2 mode low 84 V with an error of 0.83%, Medium 86 V with a error of 0.85%, High 105 V with an error of 0.81%, the Cutting mode is low 162 V with an error of 2.88%, medium 172 V with an error of 3.03%, High 192 V with an error of 2.86%. The measurement shows an error of less than 1% for Blend 1 and Blend 2 modes while cutting is less than 3%. The results of this study can be implemented in order to minimize errors due to lack of power settings and mode selection during surgery.


This paper addresses sliding mode controller design for networked control systems subject to packet loss. Possible packet loss in both transmission channels from the sensors block to the controller block and from the controller block to the actuation block are considered. A dynamic compensator is proposed. It is shown that sliding mode in mean square sense can be achieved and the closed loop control system under sliding mode is exponentially mean-square stable. An illustrative example is finally given to show the efficiency of the proposed method.


Optical microscopy is an indispensable tool in science and medicine. However, the size and cost of conventional optical microscopes limit their use in rugged field-settings or in remote areas to assist in tasks such as medical tests, disease diagnostics, or monitoring of water quality. In recent years, there has been widespread interest in reducing the size and cost of microscopes and making them more suited for point-of-care and telemedicine applications, or for tackling global health problems. These approaches range from miniaturizing traditional microscope designs and attaching them to cell phones, to eliminate lenses altogether


Objective
To investigate the clinical, endoscopic and pathological features of gastritis cystica profunda (GCP).

Methods
A total of 40 patients with GCP confirmed by pathology who received endoscopic or surgical treatment at Renji Hospital, School of Medicine, Shanghai Jiaotong University from May 2013 to May 2018, were included in the retrospective analysis. The clinical data such as population composition, clinical manifestations, endoscopic findings and pathological results were summarized and analyzed.

Results
Among the 40 patients were predominantly males (75.0%, 30/40), and the mean age of onset was 61.2 years. The most common sites were cardia (32.5%, 13/40) and gastric antrum (30.0%, 12/40). The clinical symptoms of the patients were atypical and it was difficult to diagnose GCP with routine endoscopy examination. The endoscopic findings were mostly type 0-Ⅱ (50.0%, 20/40). GCP with neoplastic lesions accounted for 55% (22/40). Unconditional logistic regression analysis showed that male (P=0.013, OR=31.093, 95% CI: 2.079-464.976) and Helicobacter pylori infection (P=0.041, OR=10.225, 95% CI: 1.096-95.411) were risk factors for GCP with neoplastic lesions.

Conclusion
GCP commonly occurs in middle-aged and elderly men, and varies in different manifestations under white light endoscopy. GCP is not a benign lesion, but can also coexist with neoplastic lesions, which are mostly differentiated intramucosal cancer.

queous film-coating processes can influence many quality aspects of the final coated product, including coated-tablet moisture content, surface roughness, gloss, coating efficiency, and coating uniformity. Colorcon's aqueous tablet-coating formulations must be capable of meeting these and other customer requirements in different application environments around the world using various types of coating process equipment. Many different tablet coating machines are on the market, each with different configuration options and different controllable process parameters. Further, different configuration options can be non-numeric. For example, some machines can be configured with one or more spray guns. This situation can result in discontinuous effects on coatedproduct quality and performance. One critical consequence is that it is not possible to define one process operating specification that is optimal for all coating conditions. The wide range of coating conditions (operating parameters, equipment, and configuration options) also has a profound consequence in terms of the development of robust coating formulations. Such a robust formulation is one that is insensitive to "normal" coating process variation. The first level of normal variation is the operating tolerances of the controllable process parameters. However, normal variation should be extended to include the likely range of uncontrollable environmental factors known to affect product Stuart C. Porter, PhD, is vice-president, and Charles R.

The research aims to study the manifestations of psychological defeat and the aesthetics of images and language in Al-Khansa's poetry, an analytical psychological reading, and it influenced Al-Khansa's poetry, because it was characterized by the sincerity of feelings and emotional feelings. Sadness, crying, pain and suffering in her poetry, and the follower of Al-Khansa's poetry in lamentation finds the echo of psychological defeat in her poems as a result of the loss of her brother and her bereavement in him. Al-Khansa's poetry, especially lamentation, prompts the reader to represent the state of refraction and pity that he sees in the poetic images, the chosen language, and the glimpse of sadness that dominates the music of her poems.We stand on Al-Khansa's poetry as a poet capable of her artistic tools on the one hand, and the weak female woman who has nothing but moans and groans and her body on the other hand to express her sadness, to reveal the subconscious side using the psychoanalytic mechanisms of the poems of lamentation and show the pent-up psychological struggles as a result of psychological and dark labyrinths that she faced with death her brother.The events begin with the broken, painful female Khansa, to unveil the effect of the psychological defeat that she went through, so she transformed her life and tried to resist it with all her strength to face the multiple psychological disorders, some of which are about to turn into a decade.Then the research aims to clarify the impact of manifestations of psychological defeat on the aesthetics of the poetic elegiac images of Khansa, to monitor its implications, and the dimensions of this effect on the elegy of Khansa in the light of psychoanalytic reading, in order to clarify the poetic image and probe the depths of the aesthetic impact and artistic formulation and for the recipient. Especially lamentation is just a feeling or a fleeting state, but it was a position and an entity, and we have summarized the reading of lamentation in conjunction with the psychological dimension, to seek the emotions of the recipient as a result of his sense of Khansa's special vision and her psychological state.


We report on the optical properties of single quantum dots in nanowires probed along orthogonal directions. We address the same quantum dot from either the nanowire side or along the nanowire axis via reflection on a micro-prism. The collected photoluminescence intensity from nanowires lying on a substrate is improved 3-fold using the prism as compared to usual collection from the top. More importantly, we circumvent the polarizing effect of the nanowire and access the intrinsic polarization properties of the quantum emitter. Our technique is compatible with the design of complex nanowire devices for the development of quantum opto-electronics.


Highly oriented, polycrystalline Pb(Zr0.5Ti0.5)O3 (PZT) thin films were successfully grown on RuO2/SiO2/(001)Si using metal–organic chemical vapor deposition (MOCVD) at 525 °C. The orientation of the PZT film was controlled by using MOCVD-deposited highly textured RuO2 bottom electrodes. A (001)-oriented PZT film was observed for growth on (101)-textured RuO2. In contrast, for (110) RuO2, the growth of (001) PZT was greatly suppressed while the growth of both (110) and (111) were enhanced, resulting in a poorly (001)-textured polycrystalline film. The as-grown PZT films exhibited a dense columnar microstructure with an average grain size of 150–250 nm. Both PZT films showed excellent ferroelectric properties without any postgrowth annealing. The (001) highly oriented PZT films showed significantly higher values of remnant polarization (Pr=49.7 μC/cm2) and saturation polarization (Ps=82.5 μC/cm2). In comparison, for the PZT films grown on (110) RuO2, Pr and Ps were 21.5 and 35.4 μC/cm2, respectively.

This paper begins by exploring how private property is related to economic development, using an economic analysis of law approach, associating scarcity with the allocation of goods and its relation to efficiency. Perhaps the solution to the dilemma between universalized access and fair remuneration to authors can be found in the new technologies. Therefore, this paper brings some information about blockchain technology that, due to its characteristics, may be problem-solving. Although legal and economic institutions that are prior to blockchain must provide guidelines so that this technology can be used to balance efforts and reward, maximizing incentives for productivity, but also ensuring fair competition and protection of public interest. Some of these institutions are analyzed in this paper, raising questions – and maybe some answers – about means and purposes of copyright protection in the blockchain era.


Binding of pesticides to serum albumin significantly influence their absorption, metabolism, distribution and excretion. In the present study, interactions of acephate, glyphosate, monocrotophos and phorate with bovine serum albumin were explored employing the UV/Vis and Fourier-transform infrared spectroscopy methods. The observed values of binding constant for titled pesticides were. phorate (1.85×107 M-1)>acephate (3.93×104 M-1)>glyphosate (1.31×104 M-1)>monocrotophos (1.12×104 M-1). Results have shown that out of four pesticides, phorate could show strong interactions with bovine serum albumin.


A large number of wireless services have been introduced over the last decade to satisfy new demands of mobile users. However, the proliferation of wireless computing and communication devices make the radio spectrum overcrowded. It is revealed in the Federal Communication Commission report that many spectrum bands are used only in bounded geographical areas or over limited periods of time, and that the spectrum utilization varies from 15% to 85%. As a consequence, the Cognitive Radio Networks (CRNs) have been introduced as a new alternative wireless communication paradigm to utilize the radio spectrum more efficiently. In this dissertation, we investigate the power control and routing perspectives to enhance the network performance and power utilization in CRN. First, aiming to enhance the network performance by deploying a proper network topology for a particular communication purpose, we propose a topology deployment oriented power control scheme for cognitive radio ad-hoc network. Second, to tackle the problem of the frequent arrival and leaving of primary users which can lead to the heavy traffic overhead caused by re-routing, we propose a new approach for joint flow maintenance and power control, called flow-based power control, for cognitive radio ad-hoc network. The power control scheme targets on to utilize the power resource more efficiently by only allocating power resource to the maintained flows. Finally, we propose an application-oriented routing protocol (AORP) in cognitive radio ad-hoc network. AORP builds the route for data transmission in combination with channel selection based on the application of the node initializing the data transmission.

Abstract : The purpose of this research was to further refine and evaluate the extent to which job embeddedness influences voluntary turnover. Specifically, this thesis sought to determine the effectiveness of job embeddedness in explaining additional incremental variance in intent to leave, above what is usually accounted for with traditional attitudinal variables. Additionally, the individual effects of tenure, education level, organizational rank, and pay were evaluated to determine if they moderated the effects of job embeddedness on a person's level of intent to leave.


Hydrological models are the simplified, conceptual and mathematical description of rainfall, runoff, oceans, rivers, groundwater, snow etc. Rainfall-runoff modeling in the broader sense a hydrological, mathematical model gives a detailed account of Rainfall-Runoff relationships of a catchment area or watershed. Conversion of rainfall into runoff takes place in the modelling. There are many methods developed for calculating the runoff. Among them the models or methods which are explained in the current study are MIKE 11 NAM Model, Soil Conservation Service Curve Number (SCS-CN) Method and Artificial Neural Network (ANN) Method. In NAM model, 9 parameters are used and adjusted for calculating the runoff. Temperature, rainfall, evapotranspiration are mainly needed. In SCS method soil information, rainfall, storm duration, soil texture, type & amount of vegetation cover and conservation practices are considered. In ANN method, a dimension is added to the modelling. The three models are explained and compared in the present study. Keywords—Rainfall-Runoff modelling, MIKE 11 NAM Model, SCS-CN Method, ANN Method.


Postbreeding migrant rufous hummingbirds (Selasphorus rufus) establish feeding territories in several habitats at Grizzly Lake, CA. Here we describe hummingbird territorial defense of tree sap made available by sapsucker feeding activity. Territorial hummingbirds fed almost exclusively on sap obtained on their territories, and they remained on the same territories for up to 6 days. The amount of energy produced on each territory was in excess of our estimates of hummingbird energy expenditures; sapsuckers, other birds, insects and small mammals remove almost all of the surplus. Comparisons of the time budgets of birds defending tree sap with those of territorial individuals in nearby habitats showed that these birds spent less time foraging and more time perching than birds in even high-quality subalpine meadows. Sap is thus a rich, easily defendable resource that may be of general value to temperate-zone hummingbirds. Utilization of sap may allow individuals to avoid critical, unpredictable energy shorta...


T wo California universities have backed off plans to phase out their ROTC programs. San Jose State University and California State University, Sacramento, both of which objected to Department of Defense policies on gays in the military, turned around after Defense officials informed them that they stood to lose millions of dollars in federal research funds under a new budget measure passed last fall.


This study is focused on the preparation of three types of silica-based composites for the capture of Cu(II) and Ni(II) ions. The first strategy consists in coating chitosan on colloidal fumed silica after acidic treatment yielding the composite SiO2+CS. The second strategy can be separated into two routes: the first one involves surface grafting of silica with aminopropyltriethoxysilane to obtaining silica particles covered by amino groups (SiO2(NH2)). The second one involves in surface condensation of triethoxysilylbutyronitrile, followed by acidic hydrolysis of the surface-bound nitrile groups affording silica particles covered by carboxyl groups (SiO2(CO2H)). In the last step, chitosan has been grafted on the surface bound NH2 or -CO2H groups yielding the composites SiO2(NH2)+CS or SiO2(CO2H)+CS. The third strategy involves in the modified CS surface with -CO2H groups, followed by coating onto the non-modified silica nanoparticles to obtain the composite SiO2+CS(CO2H). The novel hybrid materials were characterized by IR spectroscopy, scanning electron microscopy, atomic force microscopy, and zeta potential measurements. Batch experiments were conducted to study the sorption performance of these composites for Cu(II) and Ni(II) removal from aqueous solution at optimum pH at 298 K. The kinetics were evaluated utilizing pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. The adsorption kinetics followed the mechanism of the pseudo-second-order equation for all types of adsorbents. The adsorption isotherms were evaluated utilizing Langmuir, Freundlich, and Temkin models. The best interpretation for equilibrium data was given by Langmuir isotherm model. This study demonstrates that the adsorption capacities for Cu(II) ion is more efficient for the SiO2+CS (256 mg g-1) compared to SiO2(NH2) (75 mg g-1). However, the carboxyl grafted CS-coated silica (SiO2+CS(CO2H) exhibited an excellent adsorption capacity (333 mg g-1). In case of Ni(II), based on Langmuir isotherm the maximum adsorption capacity found to be 182 mg g-1for SiO2+CS, and 210 mg g-1 for SiO2(CO2H) + CS. Using single-metal solutions, these adsorbents were found to have an affinity for metal ions in order as Cu(II) > Ni(II). The adsorption of Cu(II) ion by SiO2+CS was affected by the nature of the respective anion. Application of these composite materials to remove Cu(II) and Ni(II) from aqueous solution was shown to be more efficient than the adsorption capacities of many sorbents probed by other research groups.


Gliosarcoma (GSM) is a rare primary neoplasm of the brain, characterized by a biphasic tissue pattern with alternating areas displaying glial and mesenchymal differentiation. GSM is usually treated as glioblastoma multiforme (GBM) and the prognosis is poor. Here, we discuss a 50-year-old male presenting with sudden decreased consciousness and a history of recent headache. A noncontrasted computed tomography of the brain revealed a well-circumscribed, hyperdense lesion in the left frontal lobe with significant perilesional edema, suggestive of an intracranial hemorrhage. The patient underwent emergency craniotomy to evacuate the hematoma. Intraoperatively, a mass was present, and fluid around the mass was collected and analyzed. Cytology revealed the presence of malignant cells. A 1-week postmagnetic resonance imaging (MRI) revealed a heterogenously enhancing mass in the left frontal lobe, suggestive of a high-grade glioma. The patient was then treated with radiation followed by adjuvant treatment with temozolomide plus bevacizumab. One year after the surgery, the patient was readmitted with headache, right-sided hemiparesis, and seizure. A follow-up MRI found a residual mass in the same region. A second surgery was performed. Histopathology examination showed GSM, and this was confirmed with an immunohistochemistry panel including glial fibrillary acid protein and vimentin. GSM is a rare variant of GBM. Intracranial hemorrhage is an uncommon clinical presentation of GSM. Diagnosis is established by histopathology. Treatment is surgery, followed by radiotherapy and chemotherapy. The study was approved by the Health Research Review Committee of Mohammad Hoesin Central General Hospital and Faculty of Medicine Sriwijaya University (No. 089/kepkrsmhunsri/2019) on March 1, 2019.


In the field of computer vision and image processing, image similarity has been a central concern for decades. If you compare two pictures, Image Similarity returns a value that tells you how physically they are close. A quantitative measure of the degree of correspondence between the images concerned is given by this test. The score of the similarity between images varies from 0 to 1. In this paper, ORB (Oriented Fast Rotated Brief) algorithm is used to measure the similarity and other types of similarity measures like Structural Similarity Index (SSIM), pixel similarity, Earth mover's Distance are used to obtain the score. When two images are compared, it shows how much identical (common) objects are there in the two images. So, the accuracy or similarity score is about 87 percent when the two images are compared.


The ground state of a quantum spin chain is a natural playground for investigating correlations. Nevertheless, not all correlations are genuinely of quantum nature. Here we review the recent progress to quantify the "quantumness" of the correlations throughout the phase diagram of quantum spin systems. Focusing to one spatial dimension, we discuss the behavior of quantum discord (QD) close to quantum phase transitions (QPT). In contrast to the two-spin entanglement, pairwise discord is effectively long-ranged in critical regimes. Besides the features of QPT, QD is especially feasible to explore the factorization phenomenon, giving rise to nontrivial ground classical states in quantum systems. The effects of spontaneous symmetry breaking are also discussed as well as the identification of quantum critical points through correlation witnesses.


This thesis presents a statistical imaging theory for photo-activation localization microscopy with independently running acquisition (PALMIRA). In this type of sub-resolution microscopy the switching of the fluorescence capability of macromolecules reduces imaging to the high-precision localization of individual fluorescent molecules. The point-spread function and the imaging equation of a PALMIRA imaging system are calculated and stochastic expressions for the measurement time and the confidence level of the image as a function of the spatial resolution are provided. Different localization schemes like astigmatic imaging, multi-channel defocus imaging, 4pi imaging and a multi-point setup using photo-diodes are analyzed. The theory for multi-color and polarization-resolved measurements is addressed and estimators for data evaluation procedures are provided. The role of background noise in producing artefacts is studied. Finally, it is assessed whether the quality of images can be augmented by a suitable deconvolution procedure. Furthermore, stochastic methods are applied to solve a couple of persistent problems in fluorescence correlation spectroscopy (FCS). The development of computational methods for the simulation of FCS experiments necessitates the analytical description of the architecture of a multiple-lag-time correlator that is used to estimate autocorrelations from intensity time traces. Recently, FCS has been combined with stimulated emission depletion (STED) focal volumes. The general phenomenology of STED-FCS correlation curves is studied as a function of the STED beam intensity. It is shown that the quality of a measurement is mainly determined by the fraction of signal originating from the focal plane. Then, an improved fit model taking into account the exact spatial dependency of intersystem crossing rates is presented and tested on synthetic data. Finally, the influence of second-order correlations among the points of the FCS curve on the determination of fit parameters is studied. Analytical results are provided wherever possible. Otherwise, Monte-Carlo computations are performed.


The feature extracted by the rotation invar -iants of radial Tchebichef moments could make the image analysis more effectively. However, the classical method adopted integral point sampling which has defects of too many sampling points in the centre of unit circle and insufficient samplings on the edge of the circle. It reduces the efficiency of feature extraction. In order to resolve this problem, we adopt Mukundan's square-to-circular transformation to project square image to circle grids. By making the discrete radial Tchebichef polynomials orthogonal to discrete Fourier in circumferential direction, a kind of new discrete radial Tchebichef Fourier moments can be constructed. The experimental results show that the suggested method is better than Mukundan's method as the size of image is large.


1,2-Diaminocyclohexane(isocitrato)platinum(Ⅱ)(PHIC)and1,2-diaminocyclohexane(citrato)platinum(Ⅱ)(PEX)were synthesized andcharacterized.Experiments have shown that PHIC has a strong antitumor activity againstS180,P388 and L1210 in mice at dosage of 40 and 80 mg/kg.The antitumoraction in L 1210 was also observed after treatment with PEX,but the activityis lower than that of PHIC.


THE first marked advance towards the elucidation of the arrangements and functions of the sympathetic nervous system was made in the work published by Gaskell (1) in 1888, entitled, "The structure and function of visceral nerves." In 1842 Bidder and Volkmann (2) had made the generalization that the sympathetic system was characterized by a predomIinating presence in its strands of bundles of fine medullated fibres, of very much smaller size than the large medullated fibres of the posterior roots, and therefore still smaller than the large motor fibres of the anterior roots. There was someidea that these small medullated fibres were derived from the central nervous axis, for in 1846 Snow Beck (3) writes:-" I am convinced that the'tubular fibres are derived from'the spinal nerves, and not from the sympathetic chain"; but he knew nothing of the relation of white and grey fibres. Onodi (4) in 1884 showed the connections of the white fibres, and gave a general scheme of their distribution. From amongst the many conclusions and suggestions of Gaskell's paper (1), I would here summarize three anatomical points, as being relevant to this research: 1. That small white fibres are the essential part of the white ramus communicans. 2. That these white fibresare of characteristic small size (1P8 A to 2.7 u) and bundle formation. 3. That the range of the outflow from the central axis is from the 10th to the 25th spinal nerves of the dog (2nd thoracic to 2nd lumbar) inclusive.


In this paper, robust Hinfin output feedback control problem for a class of linear discrete-time switched systems with norm-bounded uncertainty and time-varying delay is investigated. A switched dynamic output feedback controller which robustly exponentially stabilizes the switched system and reduces the effect of the disturbance input on the controlled output to a prescribed level was constructed. By using switched Lyapunov function technique, a delay-dependent linear matrix inequality-based sufficient condition for the problem to be solvable is derived. Controller design is performed by solving a set of linear matrix inequalities. Finally, a simulation example is given to illustrate the validity of the results.


A thornless variant of the trifoliate orange [Poncirus trifoliata (L.) Raf.] was found as a chance seedling. All other characters were indistinguishable from those of normal trifoliate. Genotypes of the variant at loci controlling GOT isozymes were PP,SS, whereas those of the normal trifoliate orange have been reported to be MP,SM. The variant is concluded to arise from spontaneous inbreeding of normal thorny trifoliate orange. The variant showed poor growth.


Objective: to analyze nursing technicians' knowledge about accident with needle sharp material. Method: descriptive study of qualitative approach, performed at a large-sized hospital in the state of Piauí, with 12 nursing technicians. Data were obtained through semi-structured interviews and analyzed through content analysis technique. Results: the majority showed satisfactory knowledge about accident with needle sharp material. Improper disposal of needles and blades was pointed out as the main cause of this accident. There was divergence in relation to contamination or not of the material to be considered needle sharp accident. A large part reported that this type of accident is quite distressing, disturbing and traumatic, in addition to having doubts about the notification and treatment of this accident. Conclusion: although the majority presented satisfactory knowledge about accidents with needle sharp material, there is a need for greater concern with Biosafety, continuing education and prevention of accidents to workers.


Summary DNA synthesis and mitosis in liver cells are partially inhibited 24 hours after operation in rats subjected to both partial hepatectomy and bile duct obstruction; at 48 hours regeneration is greater than after partial hepatectomy alone, although not as marked as that seen at 24 hours after partial hepatectomy. Liver cell proliferation occurs 40 to 48 hours after obstruction of the common bile duct, and is presumably the result of histologically inapparent injury to liver cells.


Children are introduced to social networking at younger and younger ages through commercially-centered virtual worlds and social gaming sites like Club Penguin, Neopets, and Webkinz. A small and growing subset of these Web 2.0 sites use social media to address prosocial values in children. This Special Interest Group focuses on "prosocial media for children", which we define as social media that strive to increase children's awareness of the lives and needs of others and promote caring about the welfare and well-being of others. Participants in this SIG are invited to join the growing discussion regarding the design and development of children's prosocial media. Participants will review 3 - 6 short examples, and then break into small groups that will host facilitated discussions about the issues and challenges surrounding design and development of children's prosocial media. A primary goal of this SIG is to foster the development of a community of researchers and practitioners who are focused on designing and developing prosocial media for children.


The installation of large-scale grid-tied photovoltaic (PV) systems are rising fast around worldwide. This rise is because the system relies on a widely available green source (sun). Furthermore, many developments were carried out to increase the PV system efficiency and decrease its total cost, which encouraged electrical companies to install large-scale PV systems. Many components must be used to construct an efficient system, including a PV array, two power electronics converters, filter and transformer. Additionally, two controllers are usually in the design. One is in charge of maximising the power for the PV modules in the array, and the second one is used to ensure the voltage is constant. The paper introduces a PV system design that can reach 1 MW connected to the grid through different stages to match up with the required voltage and frequency of the grid as a requirement for the final year project in the Electronic and Electrical Engineering Department, the University of Sheffield. The whole grid-tied PV system was designed and simulated using MATLAB/SIMULINK.


In this study, we have presented image analysis for the brain tumour segmentation and detection based on Berkeley wavelet transformation, enabled by genetic algorithm and support vector machine.

The experimental results of proposed technique is been evaluated and validated for performance and quality analysis on magnetic resonance (MR) medical images based on accuracy, sensitivity, specificity and dice similarity index coefficient. The experimental results achieved 97.77% accuracy, 98.98% sensitivity, 94.44% specificity and an average of 0.9849 dice similarity index coefficient, demonstrating the effectiveness of the proposed technique for identifying normal and abnormal tissues from MR images. The experimental result is validated by extracting 89 features and selecting the relevant features appropriately using genetic algorithm optimise by support vector machine.


Relationship marketing strategy is one of the effective options to strengthen firms' market position in this competitive age. Commitment plays central role in exchange relationships between supplier and retailer. Recent literature on antecedents of relationship marketing on inter organizational relations provide evidences that relationship commitment can yield significant benefits for firms. Although a large number of studies have been conducted on antecedents of relationship marketing, none of them covers how these antecedents influence relationship commitment between supplier and retailer. This study proposes and tests a model to examine how supplier-retailer relationship antecedents influence their relationship commitments. Collecting and analyzing survey data of 200 retailers of pharmaceutical products, this study finds significant influences of communication, trust, flexibility, reputation and dependence on relationship commitment. The findings prove that business relationships are more embedded where communication, trust, reputation and dependency can play vital roles. The correlation result shows that all the variables in this relationship are positively correlated. Based on regression results, it is observed that communication has the highest influence on supplier-retailer relationship. This result can be used as the central assumption of success for firms that reach to the top of the quality ladder. Keywords: Relationship, Commitment, Pharmaceutical products


This longitudinal study investigated the psychological wellbeing and self-esteem of students during the transition between secondary school and university. The sample comprised 197 students (82 male; 115 female). The mean age of the students at the start of the study was 18.54 years (SD = 0.78). Students completed measures of psychological wellbeing (Ryff Psychological Wellbeing Scale) and self-esteem (Rosenberg Self-esteem Scale) during their final year of secondary school and again at the start of their university studies. Repeated measures (RM) multivariate analysis of variance (MANOVA) was used to investigate how transition status and gender affected aspects of psychological wellbeing and self-esteem. Multivariate analysis showed main effect of the transition from school to university on psychological wellbeing and self-esteem. Univariate analysis indicated that psychological wellbeing was higher at the start of university studies than during the final year of secondary school, but failed to confirm the effect of the transition on self-esteem. Gender by transition status interactions for two psychological wellbeing dimensions (autonomy and purpose in life) were found.


Solar‐driven interfacial steam generation (SISG) has been recognized as a promising strategy to solve water shortages in an eco‐friendly and low‐cost way. However, the practical application of SISG is vitally restricted by some inherent limits, especially for finite evaporation rate and insufficient working life of evaporator. Herein, a novel SISG system involving an all‐fiber porous cylinder‐like foam 3D evaporator, side area‐assisted evaporation protocol, and aggregation‐induced‐emission‐active solar absorber with "one stone two birds" function is explored. The solar absorber exhibits efficient photothermal conversion, endowing the side area‐assisted evaporator with as high as 3.6 kg m−2 h−1 of solar evaporation rate, which is highly desirable for SISG under 1 sun of irradiation. Moreover, the solar absorber is capable of powerfully producing reactive oxygen species upon sunlight irradiation, which results in extraordinary photodynamic killing of bacteria nearby the fiber to prevent biofouling, consequently improving the working life of evaporator.


Background Exposure of atopic patients to a specific allergen evokes an immediate response which is followed, in many cases, by a late phase reaction (LPR) some hours later. Here we have examined the immunological mechanisms required for the expression of cutaneous LPR in mice.


For airborne air-breathing systems, flow separation is a critical factor in efficiency, ease of piloting, and performance capability. Flow separation, or stall, leads to increased drag, decreased lift, and unpredictable vibrations due to unsteadiness. Small aerial vehicle flight is one such application. On these systems, effective control of stall could provide greater maneuverability and performance, and lessened vibration during optical image capture. Separated flow is a macro-scale phenomenon and is governed by complex flow interactions but can be controlled by micro-scale actuation. For many decades, passive control methods such as vortex generators and surface roughness have been designed to mitigate separation under conditions of steady, design-point operation. Not until recently, however, has the emergence of closed loop methods enabled control of separation that is able to respond as flow conditions change. Advances in microprocessor technology have now enabled the use of sophisticated adaptive control methods that achieve separation control with linear time-varying models. While adaptive control methods have improved upon passive and open-loop techniques for steady operation, nonlinear adaptive control has yet to be demonstrated for the dynamic flow conditions of agile flight. Adaptive Sampling Based Model Predictive Control (Adaptive SBMPC), a novel approach to nonlinear Model Predictive Control, is presented. Adaptive SBMPC applies the Minimal Resource Allocation Network algorithm for nonlinear system identification and the Sampling Based Model Predictive Optimization algorithm to achieve effective feedback control of flow separation. By introducing a computationally efficient nonlinear approach to the adaptive control of separation, this research experimentally demonstrates real time control of flow separation for a range of flow conditions.


The paper explains that Initial and old concept of the doctrine of ultra vires was a concept of only lack of legal power to do an act. At present the doctrine of ultra vires is attracted in exercise of the power that is lawfully conferred on the authority concerned (whether it is legislative, administrative or quasi judicial) if it is alleged and shown that: there was lack of power to do the alleged act; there was use of improper procedure; there was use of unauthorised procedure; there was an improper purpose; there was an unauthorised purpose; there was any violation of the law of natural justice; the authority acted in bad faith; the authority acted for an inadmissible purpose; the authority acted for irrelevant grounds; that the authority acted without regard to relevant considerations; the authority acted with gross unreasonableness; the authority violated the provisions of the Constitution; the authority violated the governing Act or enactment; the authority acted in violation of the general principles of the law of the land; the authority acted so arbitrarily that no fair minded authority could have ever acted in that manner; the authority acted for improper motives; the authority acted in the manner which is repugnant to the injunctions of Islam.


This paper presents a novel digital P-I-D control FPGA for a switching power supply in the higher voltage direct-current (HVDC) power feeding system. At first, digital fast P control buck type converter is presented. Then, the appropriate number of sample point is determined. Then the fast P control is applied to the full bridge converter for HVDC. The acceptable delay time, with realizing superior dynamic response, is half of a switching cycle based on the appropriate number of sample points of buck converter. In the proposed method, the calculation processes of P and I-D controls are parallel. The delay time of P control is less than that of I-D control. The step change against the load will be discussed. It is revealed that the proposed circuit has the superior transient response. Then the proposed digitally controlled phase-shift full bridge dc-dc converter is verified with 800W proto type. The maximum power efficiency is about 92%. Then it is confirmed that proposed digital controlled phase-shift full bridge dc-dc converter achieves superior transient response compared to conventional one.


Platelets are produced through megakaryocytic lineage commitment, proliferation, maturation, and functional activation of hematopoietic stem cells (HSC). Platelets play an essential role in hemostasis and thrombosis. Megakaryocytopoiesis is regulated by many factors, including microRNA (miRNA). miRNAs are a family of 21 to 25 nucleotide small nonprotein-coding RNAs. They widely exist in various organisms and involve in transcriptional gene expression control. Recently, the roles of miRNA in regulating megakaryocytopoiesis have got more and more attention. Many new miRNAs which involve in this process have been discovered and their functioning mechanisms have been illustrated. In the future, as research continues, the new drugs or therapies based on miRNA may be applied to clinic treatment, and may benefit the patients with platelet dysgenesis. In this article, the authors will review the research progress of miRNA regulation in platelet production.

The three carbohydrates sorbitol, trehalose, and maltodextrin, differing in molecular weight, were investigated as excipients to enhance survival of the probiotic strain Lactobacillus paracasei ssp. paracasei F19 during a microwave‐assisted freeze‐drying process. This technique was further compared to conventional freeze‐drying, where thermal energy is supplied by heat conduction instead of radiant energy. Survival rates revealed similar values for both techniques after drying without protectants (~10%). While addition of maltodextrin and trehalose led to a two‐ up to threefold increase in survival for both dryings, sorbitol containing samples showed the greatest difference between the two techniques: 65% after freeze‐drying versus 12% after microwave freeze‐drying. Though protection mechanisms were generally found to be equal to conventional lyophilization, microwaves are likely to induce vibrations in the hydrophilic sugars. Thus, not all protectants which are applicable in freeze‐drying, can be applied in microwave freeze‐drying to enhance bacterial viability. PRACTICAL APPLICATIONS: A new drying process for the efficient preservation of bacterial cultures, such as lactic acid bacteria, was investigated. Microwave freeze‐drying is a much faster and less costly process than conventional freeze‐drying leading to equal product qualities and reducing the problem that drying often is the bottleneck in industrial biotechnological processes. However, no work on microwave freeze‐drying of bacterial cultures has been published so far. Knowledge on the impact of protectants on the survival of the cultures is a crucial aspect to make microwave freeze‐drying applicable in industrial processes. The selection of proper protectants is important to achieve high survival after drying and during storage.

Bachelor of social work and master's of social work students were queried regarding their use of and attitudes toward the peer-reviewed literature and understanding of and engagement in evidence-based practice (EBP). Participants were asked to assess their field instructor's use of the literature and engagement in EBP. Students felt prepared by their education to read the literature, but actually read very little. Students felt prepared by their education to engage in EBP and believed they understood what this was; few actually employed its practice behaviors. Few associations existed between classroom preparation and student attitudes and actions. In contrast, field instructors' behaviors were associated with a number of these variables. Implications for social work education are discussed as are suggestions for helping students transform knowledge into action.


In this study, it is aimed to psychometrically evaluate the Preschool Climate Scale (PSCS), which will evaluate the school climate characteristics of preschool education institutions. Both explanatory and confirmatory factor analyzes were performed in the sample of teachers and administrators (N=910). High internal consistency values were obtained from the structure consisting of 53 items and 6 subscales. Similar values were confirmed at different times and samples after testing. The results revealed that the PSCS is a valid and consistent scale.


The performance of DBP suffers from the inaccurate power map. In a single-polarization 16-QAM transmission experiment, by adding genetic algorithm optimization, we achieve 0.4-dB better performance than traditional DBP.

The author also presents his interpretation of Mr. Qian' s theory, methods and management mechanisms.


AbstractAdsorptive studies were carried out on four synthetic vinyl polymer tanning agents removal from aqueous phase onto wastewater activated sludge (AS). Batch experiments investigated the effects of contact time, dosage of adsorbate, extracellular polymeric substances (EPS), coexisted cations, and physical property of sludge flocs on the four vinyl polymers removal by AS to evaluate the kinetics, isotherms, and mechanisms. Almost 96% of polydiallyldimethylammonium chloride-acrylic-acrylamide (PDM-AA-AM), 90% of polydiallyldimethylammonium chloride-acrylic (PDM-AA), 82% of polydiallyldimethylammonium chloride-acrylic-acrylamide-hydroxyethyl acrylate (PDM-AA-AM-HEA), and 56% of polydiallyldimethylammonium chloride (PDM) were removed from aqueous solutions. The kinetics process of adsorption can be described by the pseudo-second-order kinetic equation and the adsorption isotherms fitted to the Langmuir model very well. The adsorption capacity increases with the increase in initial vinyl polymers concentr...


There is a great deal of literature that has shown benefits to students of community engagement, but few studies have looked at the benefits to the community, (Chapdelaine and Chapman, 1999, Hyde and Meyer, 2004, Strand, 2000, Hayes, 2006). We will discuss the preliminary results of a SSHRC funded project exploring the benefits to the community of engagement with universities and colleges. As part of a much larger project, we will look, specifically, at how a nationwide community organization, Vibrant Communities, is helped in its work to reduce poverty.
The first step in this project was to identify models of community university engagement. These models vary from a model where universities and a poverty roundtable from Vibrant Communities have a loose affiliation and come together to work on specific projects to a model where there is a memorandum of understanding and on-going work initiated by the community organization. An on line survey was conducted of all members of Vibrant Communities across the country asking them, among other things, to describe any community university engagement activities that they engage in, how these relationships came about and how this engagement translated their goals of poverty reduction into action. The results of this survey and the models that have been generated will be discussed in the presentation.
Secondly we will present some of the successful community university engagement projects that have occurred to date in the context of the model that they represent. These include a project to analyze the stereotypes that people have of individuals living in poverty and a community service learning project where students mentor high school students. We will share these examples as demonstrations of good practices of community-engaged scholarship.


We consider speech dialogues, allowing for simultaneous input (via speech recognition) and output (via speech synthesis or pre-recorded prompts), often referred to as "barge in". We start with a collection of dialogue situations, where simultaneous input and output is useful. It is argued, that a variety of possible system behaviour is necessary in order to take into account these situations adequately. We then define a formalism, that allows to control this system behaviour. We end up with reporting some experience gathered both in lab tests and a in real world pilot.


±. HE PERIOD 1994 THROUGH the first half of 1995 was marked by a number of significant events. Germany's ruling conservative coalition survived a turbulent election in 1994, but lost ground to center-left parties. Far-right parties became politically insignificant, due to dropping voter support and internal strife. The pullout of most foreign troops from German soil gave new political weight to unified Germany, prompting the government to start redefining the country's international role. The country's worst postwar recession ended, but recovery was uneven, and unemployment remained at close to 10 percent. Finally, a multitude of 50th-anniversary commemoration ceremonies marked the last stages of World War II and Germany's defeat and surrender. In the summer of 1994, all Russian troops withdrew from Germany, and the Western allied troops pulled out of Berlin. In July, U.S. president Bill Clinton visited Germany to assure the Germans of the strength of the U.S.-German partnership. In Berlin, Clinton visited the reconstructed New Synagogue in the eastern part of the city (see "Religion," below).


The study examined emotional intelligence, religious orientation and marital satisfaction as predictors of psychological well-being and life satisfaction among the Anglican Clergy in Anambra State, Nigeria with 435 participants sampled through cluster and random sampling methods. Valid/reliable Emotional, Marital, Religious and Well-being scales measured emotional intelligence, marital satisfaction, religious orientation and psychological well-being respectively, adopting cross-sectional survey research design and multiple regression analysis statistics. Findings: Emotional intelligence and marital satisfaction had joint and independent prediction of psychological well-being, except for the independent prediction of religious orientation on psychological well-being (emotional intelligence β =.473, t = 10.577, P <.05; religious orientation β = .074, t = 1.722, P >.05 and marital satisfaction β = .088, t = 2.054, P <.05) and emotional intelligence, religious orientation and marital satisfaction have joint and independent prediction of life satisfaction (emotional intelligence β = .220, t = 4.539, P <.05, religious orientation β = .204, t = 4.352, P >.05, and marital satisfaction β = .204, t = 4.352, P <.05). Recommendations: The Clergy should engage themselves in training to improve their emotional intelligence, so as to enhance their level of religious orientation and marital satisfaction.

Efforts of maximizing the effectiveness of foreign language instruction have lately begun to draw upon neurolinguistic research. Basically, knowledge of brain functions of learners can help teachers and curriculum designers utilize more effective teaching procedures. For this purpose, identification of learner strategies as they relate to neurolinguistic phenomena becomes paramount. This study replicated previous studies for 172 Turkish EFL learners using Oxford's (1990) scale "Strategy Inventory for Language Learning". The results indicated that the strategy used most frequently by the sample population is Metacognitive Strategies, followed by Cognitive Strategies while the least used strategy was found Affective Strategies. Based on the calculated scores, 41.3 % of the sample were found to be right-brain dominant while 37.8 % were left-brain dominant and 20.9 % were bilateral dominant. The results suggested a significant correlation between right brain dominance and memory strategies and cognitive strategies, and a correlation between whole brain dominance and social strategies.


What should the students of today be learning and doing to prepare them for system design 10 years from now? What will be the biggest challenges facing them at that time? Then too, where are the biggest opportunities for research impact right now? To help us think about such questions, we'll look back 25 years and reflect on some lessons from the early VLSI adventures of the late 70's. We'll see how separate disciplines were merged to create a new, simplified design methodology. We'll see how QTA implementation provided students and researchers with means to rapidly explore new design spaces opened by these methods. And we'll look at how a unique university/industry/government collaboration supported and motivated all these explorations. Looking ahead, we'll speculate about whether we might be at a similar "break-point" in complexity and system design challenges, and about the possibility that new innovations in system design could re-revolutionize microelectronics.


With the development of multimedia technology networks, information technology is rapidly changing the production, work and lifestyle of human society. This change has also brought important influence to education. E-learning is an emerging product under this. At the same time, English reading is a very important part in college English teaching. E-learning plays a very important role in college English reading teaching in the new era. This paper will study this phenomenon, starting from the development of E-learning and its application in college English reading education, and propose a reasonable teaching method for the current English reading teaching mode and E-learning structure. Questionnaires and other methods have verified their effectiveness, pointing out the direction for further research.

Haemaphysalis (Kaiseriana) celebensis was previously known by only a single old greatly engorged female specimen, lacking locality data, from Celebes (now Sulawesi) Island, Indonesia. Recent collecting efforts have produced more material from the Central and Southern Provinces of Celebes, mostly between 1,300 and 3,100 ft elevation. We describe the male and redescribe the female. Hosts are forest-inhabiting large mammals, the wild pig, anoa (or dwarf water buffalo), and Timor deer, and domestic horses, cattle, and Asian buffalo passing through infested forests. H. (K.) celebensis is related to H. (K.) hystricis, which occurs in northeastern India, eastward to Taiwan and southern Japan, and southward to Malaya and Sumatra. The geographical range of the H. (K.) hystricis group, with 1 species widely distributed in continental Asia and nearby islands, and 1 species localized across Wallace's line in Celebes, the "Wallacea" of zoogeographers, is notable. Haemaphysalis (Kaiseriana) celebensis Hoogstraal, Trapido, and Kohls (1965b) was previously represented only by a single greatly engorged female specimen, lacking locality data, from Celebes (now Sulawesi) Island, Indonesia. We describe the male and redescribe the female (Figs. 1-20) from more recently collected samples, all taken on the same island, from forest-dwelling wild pigs, anoa (or dwarf water buffalo), and Timor deer, and from domestic horses, cattle, and Asian buffalo passing through infested forests, mostly between 1,300 and 3,100 ft altitude. H. (K.) celebensis is closely related to H.

This paper focuses on minimising the maximum completion time for the two-stage permutation flow shop scheduling problem with batch processing machines and nonidentical job sizes by considering blocking, arbitrary release times, and fixed setup and cleaning times. Two hybrid ant colony optimisation algorithms, one based on job sequencing (JHACO) and the other based on batch sequencing (BHACO), are proposed to solve this problem. First, max-min pheromone restriction rules and a local optimisation rule are embedded into JHACO and BHACO, respectively, to avoid trapping in local optima. Then, an effective lower bound is estimated to evaluate the performances of the different algorithms. Finally, the Taguchi method is adopted to investigate and optimise the parameters for JHACO and BHACO. The performances of the proposed algorithms are compared with that of CPLEX on small-scale instances and those of a hybrid genetic algorithm (HGA) and a hybrid discrete differential evolution (HDDE) algorithm on full-scale instances. The computational results demonstrate that BHACO outperforms JHACO, HDDE and HGA in terms of solution quality. Besides, JHACO strikes a balance between solution quality and run time.


Software protection and licensing are important topics for b th the independent software vendors and software users. In Grid environments, the use of license protected ap plic tions is almost impossible and becomes a challenging task. The reasons are twofold: (i) there are no business mode ls f the independent software vendors for the Grid and (ii) there is no licensing technology suitable for Grid envi ronments. In this paper, the state of the art of license management in software industry as well as the current pract ice for managing the licenses in Grid computing is presented. The challenges and requirements of managing the software license in Grid environments are identified. Two general models developed in the European projects BEinG RID and SmartLM for managing the software licenses in Grid computing based on service level agreement (SLA) are presented. This research work is carried out under the FP6 Network of Exc ellence CoreGRID funded by the European Commission (Contra ct IST-2002004265).


I was intrigued by the Introduction to Mary Ann Glendon's new book, Abortion and Divorce in Western Law: American Failures, European Challenges. The author claims that her book will provide an opportunity to look at the evolving legal regulation of abortion and divorce from a perspective touted as a "powerful new method of legal interpretation."' Professor Glendon instructs the reader that she seeks to employ a "comparative law" perspective to examine these two areas of family law. This comparative perspective, Glendon asserts, reveals that the legal positions the United States has adopted on both the abortion and divorce issues represent "extremes" when compared with those other countries have developed. Further, a comparison of the laws in the United States with the laws of other countries assists in understanding and explaining this difference. As the title to the book indicates, Glendon views the United States' solutions to the issues involved in abortion and divorce as "failures" and believes we have much to learn from our European colleagues. Glendon concludes that in America, in contrast to most European countries, the rights of women have been protected at the expense of fetal life, and there has been a failure to consider the difficult issues the abortion controversy presents. As for divorce, she contends that legislators and judges in the United States have imple-

This article overviews recent activities carried out in the construction and tests of a 10 kW, 6.7 GHz monotron. In addition to the monotron components— injection electron gun, cavity resonator, and output waveguide—, a hard-tube pulser with three tretrodes in parallel and able to produce negative voltages up to 30kV/20A from a positive DC charging power supply is also discussed.


The design of balanced random dividing into groups is a new experimental design which links random sampling with the tests of hyptheses.This design can overcom the shortcomings probably made by the design of the complete random samling and ensure the samling with balance,and raise the accuracy of the experiments.


The current shift from the static access based service model to the dynamic application based service model introduced major challenges for effective forensics of any quality degradation of the provided service. In addition, about 55 percent of the Tier 1 and Tier 2 providers are planning to offer managed security services to guarantee an attack free IP service. In this article, we propose a novel approach of modeling the network behavior in order to select meaningful metrics to be used in tracking the network behavior changes. Based on the deftly selected metrics, we utilize an adaptive exponentially weighted moving average (EWMA) with a moving centerline control chart to monitor the changes of the network behavior. Signaling the network behavior changes in association with the service objective based network behavioral model should provide the required information for effective forensic of the service quality degradation. Our methodology is applied on both simulated and real traces of network behavioral metrics. We illustrate the effectiveness of the forensic analysis model for the selection of relevant behavioral metrics. As well, we show how the adaptive EWMA can be used for tracking the changes in the network behavior from normal to abnormal and vice versa.


Learning profile refers to ways in which we learn best as individuals. Each of us knows some ways of learning that are quite effective for us, and others that slow us down or make learning feel awkward. Common sense, experience, and research suggest to us that when teachers can tap into routes that promote efficient and effective learning for students, results are better. The goals of learning-profile differentiation are to help individual learners understand modes of learning that work best for them, and to offer those options so that each learner finds a good learning fit in the classroom.


Polymers that are sourced from truly sustainable feedstocks and have favorable physical properties can provide compelling alternatives to conventional petrochemical plastic. In this study, solution-phase anionic ring-opening polymerization is used to synthesize poly(iminomethylene(cis-tetrahydro-2,5furandiyl)carbonyl) (PITC) from 8-oxa-3-azabicyclo[3.2.1]octan2-one ((±)-1), a monomer made from lignocellulose and CO2. Under optimized conditions, the reaction proceeds to give nearquantitative yield in minutes at low temperatures. The polymer chain lengths are readily controlled by the amount of N-acetyl lactam activator up to a solubility-limited number average molecular weight (Mn) of ∼30,000. For PITC samples with Mn > 10,000, the glass transition temperature (Tg) reaches an asymptotic limit of 129 °C, which is one of the highest reported values for a nonaromatic polyamide and the highest for a lignocellulose-derived polyamide. Additionally, PITC can be chemically recycled by acid-catalyzed depolymerization and subsequent cyclization to regenerate the lactam monomer.


This paper reviews the necessity for quality systems in the specification, design and manufacture of gears to achieve required and consistent performance in service.


This study evaluates how different culinary spatula (turning shovel) designs affect cooking performance during stir-frying. A straight-handled spatula (0°) and three bent-handled spatulas (15°, 30° and 45°) were evaluated across two handle length levels (25 cm and 30 cm). The criterion measures included food-frying efficiency, work posture and subjective rating of perceived discomfort. In a laboratory experiment, 13 female participants were required to simulate a food-frying task with each spatula. The participants ranked their preference after all tests had been completed. The results showed that both the angle of the bent handle and the handle length significantly affected the four criteria. Bent-handled spatulas could effectively reduce palmar flexion/ extension and radial/ulnar deviation, and increase food-frying efficiency, comfort and subjective preference. In general, a benthandled spatula with a 15° angle and a handle 25 cm in length was the best for female cooks stir-frying task.


As the consumer culture exerts a growing influence, considerable attention has been paid recently to achieving 'happiness' and improving mental health via psychological therapies. But is it the case that individuals have 'something the matter' with them or more that society is failing to offer a sense of belonging? This paper considers whether it may be helpful to try rebuilding a sense of community and spirituality in people's everyday lives.


Present paper is a scientific study of the representation of women in media. It argues that media, being the forth pillar of the society, has a pivotal role in the attribution of gender stereotyping. The paper attempts to strive an argument that media, through its various gender projections, helps to make women more subjugated.


Of central interest to hypotheses concerning iron's role in biol. nitrogen fixation are the accessible geometries
and oxidn. states of proposed iron intermediates. Indeed, a key longstanding goal of coordination chem. is to
map the types of metal complexes that can be anticipated to have reasonable stability and to elucidate their
reactivity patterns. Such information drives to the heart of mechanistic postulates for transformations that
occur in metalloenzymes as complex as nitrogenase. Our group has an ongoing interest in exploring and
hopefully expanding the boundaries of the types Fe-N_xH_y species that can be generated and characterized.
These types of species find broader context with respect to proposed pathways for biol. nitrogen fixation. My
lecture will specifically focus on results from our lab pertaining to the types of Fe-N_xH_y complexes that are
accessible for 4- and 5-coordinate geometries. In particular, I will discuss what we now know about some
rather unusual formal oxidn. states and spin states that are synthetically available for low-coordinate iron
featuring N_2 or N_2-related ligands, ranging from Fe(I) to Fe(IV), and whether such species motivate new
hypotheses for the mode nitrogen fixation at the cofactor.
