Impact of land clearing during construction that generate dustfall and suspended particulate in ambient air is awfully obvious to observe. According to Indonesian standard as stipulated in Government Regulation (PP) no. 41/1999 pertaining to Air Pollution Control, dustfall and suspended particulate are two important parameters of ambient air quality. However, it remains a problem on how to predict the quantity of dustfall and suspended particulate that is potentially generated during construction land clearing due to lack of prediction method. In this research, a simple way to predict this number has been developed by applying mathematical expressions that are based on a series of laboratory and field experiments covering 15 soil types in Java and Sumatra Islands of Indonesia in 2013-2017. The mathematical formulas can now be implemented directly as a part of an environmental impact assessment, especially in the part of impact prediction of land clearing on air quality change. The formula consists of four parameters, i.e. soil types, local wind velocity, soil moisture content, and percentage of land cover. By inputting these four parameters in the mathematical equation simultaneously, one could directly obtain the quantity of dustfall and suspended particulate generation due to any human activity, such as construction land clearing. The quantity of the generated dustfall is expressed in [ton/km2/month], whereas the suspended particulate generation is expressed in [ug/Nm3] in compliance with the national standard of air quality, i.e. PP No.41/1999. Currently, calculation of the generated dustfall and suspended particulate could be carried out faster and even simpler by using a programmed spreadsheet containing all equations, limitations and terms of conditions that have been compiled during the last five year research campaign.


By using a simple cavity which gives a high rate of change of reactance with frequency, it is shown that the f.m. noise from a Gunn oscillator can be reduced to a much lower level than that reported recently by Faulkner and Meade.


This paper studies the incentives for fiscal adjustment for a debtor government under the risk of defaulting on its external debt. An externality arises from the bargaining process that follows default: higher tax revenues levied by the debtor lead to higher repayment to the creditor, and thus to a smaller haircut. In consequence, the optimal tax rate set by the debtor is lower than the socially optimal. If parties can negotiate contingent contracts ex-ante, the socially optimal fiscal stance can be implemented as long as creditors can commit to forgive a larger part of the debt in bad states. The model yields a different interpretation of IMF adjustment programmes and can account for some recent developments in the Eurozone debt crises.


The over-all impression regarding the inevitability of amputation in the severely ischaemic limb must be re-evaluated in the light of the present practicability of arterial-grafting. In most of the patients the determination as to whether such a procedure should be contemplated is decided by the use of arteriography. This is a simple procedure and, since we now have a better than 75 per cent salvage rate in severely ischaemic limbs, we use it in all such cases as the single most important means of determining the form of treatment—grafting, sympathectomy, or amputation—to be employed.


The present research refers to the "Validation of a forum theater as a strategy for prevention of alcohol and drugs use among students of the Technical University of Loja" is characterized by a design of mixed type, which uses quantitative methodology through descriptive analysis and qualitative methodology for content analysis.

Its main objective is to design, implement and validate a forum theater as a strategy for prevention of alcohol and drugs in students from the Technical University of Loja, with an initial population of 50 students of the subjects of Spiritual Development. Among the results we have the criteria used for the selection of the film that were correct and well developed; a forum with the invited guest expert can develop attitudes and skills. Also it was obtained that the film forum works as a strategy for prevention of alcohol and drugs among university students and finally a guide was developed for the application of a film forum that can be used in other institutions.


Depth estimation from a single image is a fundamental problem in the field of computer vision. With the great success of deep learning techniques, various self-supervised monocular depth estimation methods using encoder–decoder architectures have emerged. However, most previous approaches regress the depth map directly using a single encoder–decoder structure, which may not obtain sufficient features in the image and results in a depth map with low accuracy and blurred details. To improve the accuracy of self-supervised monocular depth estimation, we propose a simple but very effective scheme for depth estimation using a dual encoder–decoder structure network. Specifically, we introduce a novel global feature extraction network (GFN) to extract global features from images. GFN includes PoolAttentionFormer and ResBlock, which work together to extract and fuse hierarchical global features into the depth estimation network (DEN). To further improve the accuracy, we design two feature fusion mechanisms, including global feature fusion and multiscale fusion. The experimental results of various dual encoder–decoder combination schemes tested on the KITTI dataset show that our proposed one is effective in improving the accuracy of self-supervised monocular depth estimation, which reached 89.6% ( $\delta < {1.25}$ ).


Tropical cyclone (TC) intensity observations considerably improve forecast models. They are particularly used to continuously measure TC intensity for landfalling cyclones to improve their forecast. For example, TC Irving, which operated in the Gulf of Tonkin, South China Sea, on 23–24 July 1989, was observed by a conventional weather radar installed at the Phu Lien Observatory in North Vietnam. The maximum wind speed was calculated by the hyperbolic-logarithmic approximation (HLS-approximation) of spiral cloud-rain bands (SCRBs) of recorded TC radar images. The data spanned about 15 h. Ground-based estimates of the cyclone intensity were obtained from pressure measurements at two coastal weather stations. A comparison of these estimates with the HLS wind resulting from the HLS approximation of SCRBs showed satisfactory synchronization. In particular, radar and meteorological data indicated cyclone intensification near landfall and rapid cyclone intensification after landfall. Both intensifications were accompanied by polygonal eye shapes. This study demonstrates the feasibility of using the HLS-approximation technique for retrieving TC intensity variation from conventional weather radar data.

Since the appearance of the western flower thrips, Frankliniella occidentalis, in European glasshouses, many attempts have been made to improve the biological methods for thrips control, originally based on the control of Thrips tabaci. Introductions of Neoseiulus (Amblyseius) cucumeris have been increased with respect to both numbers per introduction and number of releases. So-called slow-release systems have been developed to ensure better establishment of the predator on the plant. New control agents have been tested: the predatory bug Orius insidiosus and the entomopathogenic fungus Verticillium lecanii. Additional control methods are: 1) the use of polybutenes as an insect glue on yellow polythene covers of the rock-wool mat; 2) newly developed blue sticky traps. These new developments and prospects are discussed.


THE OBJECTIVE OF THE WORK
Is to study the character of deflection of fragments of a semi-jacketed shell (a semi-jacketed bimetallic bullet with a lead core of a 5.45×39 mm cartridge for the Saiga carbine) and the ejection of fragments of the triplex glass shot with it. The experiments results showed that when a triplex glass pierced at an angle of 60° with respect to the sightline, there is a deflection towards the normal line of the flight direction of the shell and obstacle fragments. The shell speed far exceeds the ballistic limit, but the fragments speed is much lower and the trajectory is formed by alternating waves of compression and decompression.


By coupling flexible energy facilities such as the PEM electrolyzer cell with coal-fired power units, the flexibility of the coal-fired power platform can be significantly improved, which is the key solution for the challenges of system frequency regulation caused by the high penetration of renewable energy in power system. In order to dispatch resources properly and improve the flexibility of power system while ensuring the optimal economy, this paper proposes an optimized economic dispatching approach for PEM electrolyzer cell combined with coal-fired power units to participate in frequency regulation service. First, we analyze the revenue of frequency regulation auxiliary service and establish the revenue model. Then, the frequency regulation characteristics of PEM electrolyzer cell and coal-fired power units are elaborated and compared. For dispatching single frequency regulation signal properly, we take the economy as the optimized objective and consider constraints related to the units ramping rate, capacity and signal amplitude, etc., and proposed an optimized economic dispatching approach for the PEM electrolyzer cell combined with a coal-fired power units in a single frequency regulation. When the frequency regulation service stress high requirements for the response time, the economic dispatching table of the integration system under the single regulation signal can be formulated before by the proposed approach before service. A calculation case is carried out, and the results show that the proper dispatching frequency regulation signal among different units by the proposed approach can improve the flexibility of units in frequency regulation while ensuring the optimal economy, which provide a reference for coupling operation between flexible energy facilities and coal-fired power units.


A rare complication of vacuum extraction delivery is subgaleal hemorrhage which may be associated with significant morbidities such as anemia, hypotension, persistent metabolic acidosis and hyperbilirubinemia. Background: Instruments such as vacuum extractors and forceps are used in ten percent of all vaginal deliveries. Currently, in the United States, the use of vacuum extractors is twice as frequent as that of forceps. A rare, but potentially lethal complication of vacuum extraction deliveries is subgaleal hemorrhage (SGH). This potentially lethal complication of vacuum extraction vaginal delivery is frequently unrecognized or incorrectly diagnosed. More importantly, the pediatric literature in the United States is devoid of a systematic reports and review of this not very infrequent neonatal problem. Methods: Fifteen cases of SGH following vacuum extraction deliveries are presented with detailed descriptions of two cases, one resulting in death and another resulting in long-term morbidity. With this case reports, current literature was reviewed and a detailed description of the instrumentation, frequency of its use, traumatic complications, predisposing risk factors, clinical features of SGH, its recognition, and its differential diagnosis is provided. Results: SGH was frequently associated with intracranial hemorrhage and/or cephalohematoma making its diagnosis more difficult by the healthcare providers. Moderate to massive size SGH was associated with anemia, metabolic acidosis, hyperbilirubinemia, intracranial hemorrhage, respiratory distress, seizures, shock, and death. In most cases, SGH following vacuum extraction vaginal delivery was not recognized or there were significant delays in correct diagnosis. The delay in correct diagnosis and the institution of early and appropriate treatment may have resulted in significant morbidity and even mortality. Conclusions: It is recommended that the neonatal healthcare providers should be made aware when vacuum extractors are used, and be familiar with possible complications associated with its use. If vacuum extractor is used, neonates should be frequently evaluated for early diagnosis of SGH, and the institution of early treatment should be implemented with the hope of minimizing neonatal morbidity and mortality.

Schistosoma mansoni infection in mice has been fingerprinted using CE to study the capabilities of this technique as a diagnostic tool for this parasitic disease. Two modes of separation were used in generating the electrophoretic data, with each untreated urine sample the following methods were applied: (i) a fused‐silica capillary, operating with an applied potential of 18 kV, in micellar EKC (MEKC) and (ii) a polyacrylamide‐coated capillary, operating with an applied potential of −20 kV under zonal CZE conditions. By combining normal and reverse polarities in the data treatment we have extracted more information from the samples, which is a better approach for CE metabolomics. The traditional problems associated with variability in electrophoretic peak migration times for analytes were countered by using a dynamic programming algorithm for the electropherograms alignment. Principal component analyses of these aligned electropherograms and partial least square discriminant analysis (PLS‐DA) data are shown to provide a valuable means of rapid and sample classification. This approach may become an important tool for the identification of biomarkers, diagnosis and disease surveillance.


Questions of economy of fuel by use of secondary power resources in the last years have turned to an actual problem and are a nation-wide problem. Industrial consumers use now over 60 % of all extracted fuel and about 70 % of all produced electric power. The factor of useful use of energy in engineering procedures remains still low and constitutes an order 35 40 %. One of effective directions of salvaging of warmth resources is production of a cold for the enterprises. But, dealing with a question about rational and effective utilisation, it is impossible to forget that along with cold reception processes of transformation of warmth with low-temperature level on higher can be carried out also. In the article the author opens, how use of the thermal pump allows to increase factor of useful use of energy in engineering procedures to 75-80 %.


Vinyl-terminated isotactic polystyrene macromonomers were copolymerized with ethylene and 1-octene to new polyolefin graft copolymers with crystallizable polystyrene side chains. The iPS content was varied from 4 to 78 wt.-% using different metallocene and halfsandwich catalysts. No solubility problems of the stereoregular macromonomer occured, because iPS does not crystallize during polymerization. In addition the polymers show nanophase separation of the polyolefin backbone and the iPS side chains. The crystallization of iPS, having a melting point of about 200°C, can be achieved by annealing. This synthesis strategy allows the fabrication of a new class of thermoplastic elastomers with improved heat distortion temperatures.


Cross-domain data analysis is playing an increasingly important role in media convergence and can be adopted for many applications. Most existing methods consider the domain discrimination as the multimodal representation difference or the imbalanced item classification distribution, ignoring the different tag semantics among domains. To this end, we propose an explainable cross-domain multimodal supervised latent topic (CDMSLT) model and evaluate our model on two applications. First, we learn a common topic space that is capable of explaining both domain specification and commonality. Second, we apply our model to a multilabel classification task and put forward a cross-domain item tagging method. Third, combining user behaviors and the CDMSLT model, we propose a cross-domain recommendation algorithm that could estimate the user preference on new unseen domains. This article proves the effectiveness of the CDMSLT model by comparing these two applications with existing algorithms in a cross-domain scenario on the Douban dataset.


The pattern of one hundred and eight generals put in order in Chinese classic Outlaws of the Marsh is not like that of legendary position in name list based on martial feats but bears a striking feature of independent temple politics, fully showing Song Jiang's superb arts of leadership and the system attained and ideas guarantied after summoning rebels and other unaffected groups. The seat arrangement in the works is a paragon condensed by our traditional political sense.


Simple Summary The current work evaluates the application of solid-state fermented wheat bran supplemented with agrimony extract in broiler nutrition. Broiler production parameters, blood and bone variables and meat quality were analysed. The quality of breast and thigh meat was evaluated by the use of physicochemical variables, fatty acid profile, lipid oxidation and sensory variables. The presented results showed that supplementation of the broiler diet with fermented feed positively influenced the quality of the produced breast and thigh meat. The application of fermented feed increased the nutritional value of broiler chicken meat, as shown via the positive modification of the fatty acid profile, without affecting sensory quality. Abstract The impact of the broiler diet modification on the following parameters was evaluated: meat quality, carcass traits, and bone and blood parameters. One hundred twenty one-day-old COBB 500 broiler chickens were assigned to three experimental groups (40 birds per group) with four replications (10 per pen) for 35 days of fattening. The control (C) was fed a basic feed mixture. The diet supplemented with 10% of fermented feed (FF10) and additionally supported by 0.2% of agrimony extract (FF10 + AE) was applied to the second and third groups, respectively. FF10 showed both a lower average daily feed intake and total feed consumption when compared to that of C (p < 0.05). Lower concentration of alkaline-phosphatase and calcium and higher total lipids and triglycerides in blood were observed in FF10 + AE. Breast and thigh meat showed a lower content of polyunsaturated fatty acid n-3 and n-6 in the FF10 + AE group (p < 0.01). The increase of gamma-linolenic acid content in breast and thigh meat samples obtained from the experimental groups was significant (p < 0.001 and p < 0.05; respectively). Lower lipid oxidation was observed in the thigh muscle of the FF10 + AE group on the first day of storage (p < 0.01). The current study indicates that FF10 + AE supplementation can be successfully applied to enhance broiler performance and meat quality.

Priority vectors in the Analytic Hierarchy Process (AHP) are commonly estimated as constant values calculated by the pairwise comparison ratios elicited from an expert. For multiple experts, or panel data, or other data with varied characteristics of measurements, the priority vectors can be built as functions of the auxiliary predictors. For example, in multi-person decision making, the priorities can be obtained in regression modeling by the demographic and socio-economic properties. Then the priorities can be predicted for individual respondents, profiled by each predictor, forecasted in time, studied by the predictor importance, and estimated by the characteristic of significance, fit and quality well-known in regression modeling. Numerical results show that the suggested approaches reveal useful features of priority behavior, that can noticeably extend the AHP abilities and applications for numerous multiple-criteria decision making problems. The considered methods are useful for segmentation of the respondents and finding optimum managerial solutions specific for each segment. It can help to decision makers to focus on the respondents' individual features and to increase customer satisfaction, their retention and loyalty to the promoted brands or products.


Medium-wave radio broadcasting in Japan has been disturbed by jamming from neighboring countries. To deal with this problem, consideration should be given to the use of numerous low-power broadcasting stations, each with a rather narrow service area. A helical loaded monopole antenna is recommended for use in such stations. A field experiment was conducted using a model one-tenth the size of the actual antenna. The antenna impedance was almost identical to the theoretical and the apparent efficiency was 32 percent at an antenna height of 0.1 wavelength.


The structural, electronic, and optic properties of the In2O3(ZnO)n system are studied by the combination of high-resolution electron microscopy, image simulation, and density-functional theory calculation. We find that the In2O3(ZnO)n system has a polytypoid structure that consists of wurtzite InZnnOn+1 slabs separated by single In–O octahedral layers. These octahedral layers are inversion domain boundaries and satisfy the electronic octet rule. The InZnnOn+1 slabs contain another type of boundary that inverts the polarities again. This boundary prefers a zigzag modulated structure and also obeys the electronic octet rule. We also found that the red-shift in optical transitions for the In2O3(ZnO)n system as compared to individual In2O3 and ZnO systems is because the symmetry-forbidden band-edge transitions found in In2O3 are overcome by the formation of the superlattices, with ZnO contributions to the top of the valence band. We further find that the increasing n results in an enhanced valence-band maximum in the ZnO region, while the conduction-band minimum becomes more localized on the InO2 layers, which introduces confinement to electron carriers. Such enhanced localization explains why Znrich compounds (higher n) exhibit lower conductivity.


Spectral estimation of three-phase electrical signals is a well proven technique for the condition monitoring of electrical machines. To overcome the limitation of the Fourier Transform, recent studies have focused on the use of parametric spectral techniques such as the Maximum Likelihood or subspace approaches. In this paper, we propose to improve the estimator performance by using the phase diversity. Using a statistical analysis, we theoretically demonstrate the benefit of using the phase diversity for frequency estimation and show how to extend single-phase estimators to the three-phase case. Finally, we illustrate the advantage of our proposed methodology for the condition monitoring of electrical motors.

It is a generally accepted fact that every child follows a different pace of development. The main protagonists of participation in physical education and physical activity are the children and the teacher. Active participation in physical education and physical activity can be a challenge for children with special educational needs (SEN), and adapted physical education and maintaining physical activity can be a challenge for teachers. The focus of the article is the physical activity of children with special needs and the methods that help them develop an active lifestyle. The study emphasizes the importance of adapting physical education and using individualized programs in order for all children to successfully participate in physical education activities. However, the topic is not new, and the author points to foreign and domestic research that examines the importance of regular physical activity for children with special needs. What is new, however, is that the article examines the topic from the child's perspective and focuses on solutions. The announcement highlights a permanent process to ensure that all children can successfully participate in physical education activities. The article discusses in detail the possibilities of adapting physical education and physical activity, which satisfy the unique needs of children with SEN, which affect the following topics: characteristics of children with SEN, the importance of physical activity, adapted physical education programs, treatment of problems in the psychomotor area, ensuring successful participation, as well as modification options and suggestions.


When single-phase grounding fault occurs at the low-voltage side of excitation transformer,the ping-pong type rotor grounding fault protection may detect the reduction of grounding insulation resistance and misconstrue it as the single-point grounding fault of excitation winding with location percentage of 50 %.A method to online identify the single-phase grounding fault at the low-voltage side of excitation transformer is proposed. The criteria are:the calculated rotor winding grounding resistance is smaller than the setting value;the grounding location percentage is about 50 %;and the ratio of the fundamental voltage at any terminal of excitation winding to the excitation voltage is larger than the setting value. Theoretical analysis and field waveform records prove its correctness.


The effects of defect sites and coadsorbed iodine atoms on the chemistry of alkyl groups with two to four carbon atoms on copper surfaces have been studied by temperature-programmed reaction (TPR). The primary reaction pathway for the adsorbed alkyl group both in the presence and absence of defects and iodine atoms is @-hydride elimination. Because desorption is not (under most conditions) the rate-determining step in the evolution of the product from the surface, the rate of the surface @-hydride elimination reaction could be monitored by TPR. Neither surface defects nor low coverages of coadsorbed iodine significantly affect the @-elimination rate. For high coverages of iodine, however, the rate of @-elimination by 5-10% of the adsorbed alkyl groups is decreased by over five orders of magnitude ( Trxn = 385 K versus 230 K). The reaction kinetics together with observations from low-energy electron diffraction studies 'suggest that the dramatic inhibition of the @-elimination rate for high iodine coverages is due to cages of immobile iodine atoms that surround the alkyl groups and prohibit hydrogen transfer to the surface. Try as we may, no transition-metal single crystal is perfect. Scanning tunneling microscopy studies have shown that steps, kinks, adatoms, and vacancies are present at a fraction of a percent on even the most carefully prepared surfaces.' Because surface defects contain atoms that are coordinatively unsaturated relative to terrace. planeatoms, reactivity at defect sites is often enhanced, leading to dramatic effects on surface reactions despite their small numbers. For example, polyolefin formation using Ziegler-Natta type catalysts is thought to occur exclusively at defect sitesO2 The important role of defect sites on surface reactions has recently been reviewed by Wandelt.3 Like surface defects, elemental coadsorbates can dramatically affect surface reactions. The promotion of the Haber process by alkali additions' and the poisoning of hydrocarbon reforming by small amounts of sulfurs are well-known examples. The chemical mechanisms for these effects remain controversial, and the question of whether steric (site-blocking) or electronic effects are dominant continues to be debated.6 In the present work, we examine the effects of surface defects and coadsorbed iodine atoms on alkyl dehydrogenation by @-hydride elimination on single-crystal copper surfaces using temperature-programmed reaction (TPR) experiments. TPR is particularly useful for this system, because the rate of dehydrogenation determines the rate of product evolution, Le., for most conditions, desorption is not rate-determining. The rateof product evolution can thus be used to monitor the rate of the surface dehydrogenation reaction. Previous studies of this system have shown that linear alkyl iodides of two to four carbons in length dissociate below 150 K on copper surfaces to form adsorbed alkyl groups and iodine atoms.'J As shown in Scheme 1, these alkyl moieties dehydrogenate by 8-hyride elimination above 200 K to form adsorbed hydrogen atoms and the corresponding olefin, which desorbs from the surface.8.9

A 69-year-old man with a progressive myelopathy for 2 years was referred for evaluation of suspected transverse myelitis. His medical history included discectomies, a severe episode of herpes simplex virus type 1 meningoencephalitis, and development of insidiously progressive numbness and weakness of his hands. Cervical spine magnetic resonance imaging showed 2 small, dural-based, gadolinium-enhancing lesions. Biopsy of these lesions showed only normal neural tissue. Subsequently, the dura was stripped away surgically from the lower cervical region, in an effort to remove these lesions. During the next year, a sensory level developed at about the level of the nipples (T4), along with a squeezing sensation on his trunk below. Imbalance and bilateral lower extremity weakness and numbness then developed. Magnetic resonance imaging showed a longitudinally extensive cord signal abnormality.
 The cause of the patient's initial subjective hand numbness and weakness was indeterminate. The onset of severely progressive symptoms after surgical removal of those lesions and the reported stripping of dura made it likely that the progressive cord edema was due to chronic adhesive arachnoiditis. His prior meningoencephalitis was a potential additional risk factor for arachnoiditis. Computed tomography myelography showed a markedly abnormal spinal canal with scalloping of the cord contour, with delayed flow of contrast above C6-C7, consistent with arachnoid adhesions causing obstruction of normal cerebrospinal fluid flow.
 The patient was diagnosed with chronic adhesive arachnoiditis.
 A C4-C7 laminectomy and surgical lysis of the cord meningeal adhesions was performed, with subsequent intensive neurorehabilitation. Follow-up spinal cord magnetic resonance imaging 6 months after surgery showed improvement of the T2-signal abnormality but persistent myelomalacia and spinal cord atrophy.
 Adhesive arachnoiditis is an uncommon cause of progressive myelopathy resulting from an insult to the arachnoid meningeal layer, followed by inflammation and fibrosis. This process renders the arachnoid abnormally thick and adherent to the pia and dura mater. Abnormal adhesion of nerve roots or spinal cord to the dura produces neurologic impairment. Typical symptoms include back pain, paresthesias, lower limb weakness, and sensory loss. It is diagnosed clinically with supportive magnetic resonance imaging and computed tomography myelography findings.


Ojala, Arto Internationalization of software firms: Finnish small and medium-sized software firms in Japan Jyväskylä: University of Jyväskylä, 2008, 57 p. (+ articles) (Jyväskylä Studies in Computing, ISSN 1456-5390; 89) ISBN 978-951-39-3251-0 (PDF), 978-951-39-3130-8 (nid.) Finnish summary Diss. This dissertation investigates internationalization of small and medium-sized software firms first from a general point of view and, thereafter, from the point of view of the Japanese market particularly. The quantitative findings in this dissertation suggest that small and medium-sized software firms enter the large software markets very early in their internationalization process. However, the Japanese market seems to differ from this trend. For this reason, qualitative case studies were employed to elaborate the market entry and entry mode choice of Finnish small and medium-sized software firms in the Japanese market. The findings imply that these firms entered Japan at a very early stage by using direct entry modes. This was mainly due to the market size, sophisticated industry structure, and requirements for intensive cooperation with the customers during the sales process. The firms' product offering was also found to be closely related to the entry mode choice in the market. Despite of the psychic distance between Finland and Japan, the firms were able to enter the market by hiring local employees and western managers who already had working experience in the Japanese market. Moreover, the findings suggest that the firms actively seeking market opportunities in Japan used formal or mediated relationships, whereas the passive firms were invited into the market through their informal relationships. Investigation to the success factors and entry barriers in the Japanese market revealed that the success factors and entry barriers are mainly related to the firms' business execution capabilities to operate in the market. The summary part of this dissertation analyzes how these findings can be explained by using the Uppsala internationalization model, the network model of internationalization, and the international new venture theory. Based on the findings, none of these theories alone does adequately explain the internationalization behavior of small and mediumsized software firms. For this reason, a new model that integrates these three theories, to the appropriate extent, is being developed. The model emphasizes the software firms' product strategy as the main driver for the internationalization behavior.


This paper describes experimental and numerical results of Electromagnetic (EM) pulses caused by Electrostatic Discharge (ESD) in the IEC802.2 standard set-up. Results obtained by combined Spice-TLM model of the ESD event were compared with E and H field measured by a small optically linked field sensor. They enable the distribution of the EM field above the conductive table to be determined. This provides an opportunity to estimate of the induced currents and voltages in sensitive elements during ESD testing.


A unique zinc–hexamethylenetetramine coordination complex (ZnHMT) has been developed through a facile and fast solution-based method. The ZnHMT complex delivers an exquisite flower-like nanoarchitecture assembled by ultrathin nanosheets, which not only facilitates the electrolyte infiltration and ion transfer, but also implements efficient exposure of active interfaces. Meanwhile, the strong chemical interactions between ZnHMT and polysulfides render potent sulfur immobilizations, contributing to effective inhibition of the shuttling behavior. As a result, Li–S cells with a ZnHMT-based interlayer achieve excellent cyclability over 1000 cycles, superb rate capability up to 5C and a high areal capacity of 5.9 mA h cm−2 under raised sulfur loading.

This paper established an ion chromatography(IC)method to determine focal phosphates in the meat,i.e.,tripolyphosphate,pyrophosphate,and hexametaphosphate. Samples were extracted with pure water. Chloroform is used as a precipitation agent,and the IC has the automatic eluent generator. Under the optimized conditions,the recoveries of three phosphates were between 88.4%-108.6%,the RSDs were less than 10%. The limits of detection were 0.06,0.14 and 1.6 μg/L respectively. This method was proved to be simple,high sensibility and suitable for the analysis of meat products in daily life.

The standard project for Health Buildings, as in the case of Basic Health Units (BHU or UBS in Portuguese) is inserted as a building that provides municipalities with advantages of constructive rationalization and savings in the construction process. However, environmental comfort conditions are not systematically considered as a design principle. The adequacy of the projects must, among other aspects, consider adequate implantation and orientation of the buildings, besides guaranteeing a low energy consumption. This paper aims to evaluate the use of standard projects (for two typologies of BHU) regarding energy efficiency and Natural Ventilation. For this first parameter, the criteria established by the Evaluation based on the Technical Quality Requirement (RTQ) for commercial, service and public buildings regarding the envelope were considered. For the second parameter, these typologies were simulated in the four guidelines indicated by the RTQ-C in PHOENICS software that uses the Computational Fluid Dynamics (CFD) principle in order to identify regions with positive and negative pressure and the potential for using natural ventilation in these buildings. The results showed that it is possible to use the projective configuration, provided that some precautions are taken, especially concerning the use of materials from the building envelope systems. This research is expected to present a proposal for the implementation of the Standard Project that is more adapted to the conditions of thermal performance, and that can provide greater comfort to users.


Abomasal obstruction commonly occurred in the cattle which have strong physic condition and grazing fast but extensive feeding and management.The author treated 3 case of bovine abomasal obstruction which were related with the habits of feeding cattle with tomato and potato skin.Two of the 3 were cured and one was dead due to delay treatment.Etiology,diagnosis and methods of cure were discussed also.


Two of the winners of the 2001 Nobel prize in physiology or medicine, announced on Monday, will have come as no surprise to students of this coveted award. Sir Paul Nurse, director of the Imperial Cancer Research Fund in London, and Dr Leland Hartwell, director of the Fred Hutchinson Cancer Research Center in Seattle, have both been hotly tipped for the past few years.

Vascular epiphyte communities, comprising up to 25 percent of tropical forest flora, contribute to plant diversity and thus ecosystem‐level processes; however, one of the proximal determinants of those communities, microclimate, is little studied. Here we present the first comprehensive study of microclimates in the inner crowns of two emergent tree species, Hyeronima alchorneoides and Lecythis ampla, at La Selva Biological Station, Costa Rica. We examined photon flux density, temperature, vapor pressure, and humidity in inner‐crown branches during the wet and dry seasons and during the wet‐season leafless phase of Lecythis. In both seasons, the percentage daily PFD in foliated Lecythis crowns (9%, wet season; 11%, dry season) was significantly higher than in Hyeronima crowns (5%, both seasons), with the leafless wet‐season PFD of Lecythis reaching 23 percent of full sun. Temperature and vapor pressure varied less in Hyeronima than in Lecythis crowns during the dry season. Microenvironmental conditions for epiphytes within Hyeronima crowns were more spatially and temporally homogeneous and were more buffered from ambient conditions than within Lecythis crowns. Growing conditions within the crowns of the same trees and among different trees were measurably different and are likely to affect the structure and composition of the resident epiphyte communities.


Carotid intervention for the amelioration of symptoms due to carotid stenosis has been a controversial therapeutic concept for much of its history. Operative carotid surgery (carotid endarterectomy) underwent considerable turmoil and challenge during the late 20th century, eventually becoming a generally accepted approach in the management of symptomatic critical carotid artery stenosis. A similar circumstance currently confronts carotid angioplasty. Carotid endarterectomy (CEA) now represents the clinical standard against which any carotid intervention is compared and carotid angioplasty must "measure up" to this reference procedure. However, it must be recognized that the time line for acceptance of CEA measured approximately 40 years suggesting that the clinical community must exercise patience in the evaluation of carotid angioplasty which enjoys a relatively short history. Conversely, there is considerable vested interest by several specialties for carotid angioplasty to be accepted (cardiology, radiology) or rejected (vascular surgery) indicating the need for critical analysis of this procedure's efficacy. This process of procedure assessment remains a difficult task in view of the constantly changing technological advances that surround this field. This chapter focuses on the key elements of technique and clinical experience which represent the status of carotid angioplasty today.


This article aimed to report the Journal Impact Factor (JIF) of articles published in 68 Thai academic journals within the scope of this article, the calculations of the JIF being based on those by the Institute for Scientific Information (ISI). This was the first time that the impact factors of the Thai academic journals were investigated. This work was restricted to only 68 journals being cited during the last five years (from 1996 to 2000). The results showed that only six journals; namely, (i) Songklanakarin Journal of Science and Technology, (ii) Kasetsart Journal: Natural Science, (iii) Entomology and Zoology Gazette, (iv) Ladkrabang Engineering Journal, (v) Suranaree Journal of Science and Technology and (vi) Chulalongkorn Medical Journal, have been cited continuously (being estimated to be 8.8% of the journal numbers in this work). In addition, it was notieable that articles published in longer journal age tended to have greater opportunity to be cited and higher journal impact factor. The average impact factor of the journal swithin the scope of this article was calculated to be 0.069, suggesting that the possibility of an article published in a national journal to be cited was approximately 6.9%. Further work based on these preliminary results would be considering the existing method of calculating the impact factor whether or not it is suitable for Thai academic journals, also developing a more suitable alternative method for the impact factor calculation for the Thai journals, and its applications.


In THF solution [{(thf)2Mg{μ-C(CH3)2C2H4(CH3)2C}}2] (1) exchanges the alkanediide ligand with [{(thf)2Mg{μ-CH2)5}}2] in an equilibrium leading to the formation of [{(thf)2Mg}2{μ-C(CH3)2C2H4C(CH3)2}{μ-(CH2)5}] (2). Depending on the crystallization temperature, homoleptic 1 or heteroleptic 2 crystallizes from THF solutions, verifying a temperature-dependent Schlenk equilibrium. Irradiation of a solution of 1 in [D8]THF with UV light yields magnesium hydride and alkene via a β-hydride elimination reaction. In a metathetical approach dichlorophenylphosphane reacts with 1 in THF to give the intermediate "PhP(Cl){C(CH3)2C2H4(CH3)2CMgCl" (3-MgCl), which forms three subsequent products. In order to ease handling and characterization of these compounds, hydrolysis and oxidation with sulfur has been performed. This product mixture was separated by column chromatography, yielding the chlorophosphane sulfide [Ph(S)P(Cl){C(CH3)2C2H4(CH3)2CH)}] (3-S), the cyclic phosphane sulfide [Ph(S)P{C(CH3)2C2H4(CH3)2C)}] (4-S), an...


This thesis deals with the sedimentary characteristics, brittle structures, and prospecting methods of the Flammet Quartzite (loc. Offerdalsskiffer), a dimension stone quarried in the Swedish Caledonides. The two main areas of emphasis are firstly the exploration in an area of no bedrock exposure, and secondly the assessment of the deposit. The Flammet Quartzite is quarried within the Offerdal Nappe at the Landögssjön area, in the county of Jämtland, Sweden. The Offerdal Nappe belongs to the lower part of the Middle Allochthon of the central Scandinavian Caledonian thrust belt, and contains three tectonostratigraphic units separated by thrust displacement. The Offerdal Nappe is correlated with the riftogenic Risbäck paleobasin. The Risbäck basin is characterised by coarse clastic sediments dominated by fluvial deposits passing laterally into lacustrine and various marine facies. The extracted rock material is derived from subunit D of the local stratigraphy of the Finnsäter region, which belongs to the lower part of The Upper Tectonostratigraphic Unit (UTU) of the Offerdal Nappe. Subunit D is composed of feldspathic metasandstone with a sharply defined compositional layering differentiated into cleavage domains and microlithons. The cleavage domains are characterised by oriented phengitic muscovite and microcrystalline quartz, and the microlithons are made up mainly of recrystallised quartz and feldspar. The cleavage has an average frequency of 4 cleavage planes/10 mm. The thickness of the cleavage domains varies between 0.5 to 1.5 mm with crenulation amplitudes of up to 0.5 mm. The persistency of parallel series of cleavage planes can be traced for several meters (> 5 m). Fracture studies within the Nya Finnsäter quarry have defined 3 main fracture sets. Mean direction of orientations are 277/85,149/89 and 208/86 with an estimate of mean fracture trace length of 4.4 m, 3.4 m and 8.0 m respectively. Fractures oriented along 208° and 149° occur in fracture zones that are generally traceable along the full length and width of the Nya Finnsäter quarry (more than 150 m). Based on the presence of larger continuous fracture zones, it is possible to predict fracture frequencies in non-accessible areas (i.e. areas covered by drift material). By extrapolating fracture traces from a small mapping window a rough picture of the geometry of the local fracture system can be obtained. For example, in a trench 30 50 m long and 1 m wide excavated down to bedrock, a valid fracture prognosis can be made extending 14 m to either side of the trench. The fracture prognosis also takes into consideration natural and induced fractures. Two types of fracture occurrences related to blasting have been defined; type A coalescing fractures with at least one end terminating in a drill hole, and type B coalescing fractures with one end terminating in a type A fracture. Fractures of type A increase the fracture frequency to 23 %, type A and B together increase the fracture frequency to 36%. In this investigation, approximately 17 % of the rock volume shows increased fracturing from the blasting operation.

Lots of diseases are accompanied by symptoms of anemia in clinical. Erythrocyte apoptosis may contribute to anemia. Inner genetic defects of erythrocytes, some diseases via internal and external ways causing the body's damage mechanism, such as high antioxidant mechanism defects, oxidative stress, osmotic pressure, lack of energy, the synthesis and release of prostaglandin (PG) E2 and platelet activating factor (PAF), complement activation, may trigger erythrocyte apoptosis, thus cause varying degrees of anemia and microcirculation dysfunction. Meanwhile, erythrocyte apoptosis also plays an active role in the protection of body during occurrence and development of some diseases associated to anemia. In this paper, we review the role of erythrocyte apoptosis in diseases associated with anemia and its protection to body.

This article is dedicated to the "linguistic" strategies, exercised by Russia in humane and educational space of the former Soviet Republic of Uzbekistan. The most important conclusion of the present work states that thorough evaluation and typologisation of the strategies lays the basis for the future language and educational strategy of Russia and estimates the position of Russion language and culture in this highly strategically important region.


Since figures of speech have widespread use in nearly all genres of communication and writing, the translation of them becomes really important and urgent. So, this paper was conducted in order to assess the translation of "figures of speech" by humans and machine and compare them in order to achieve an insight of their capability while encountering with these linguistic features. To this end, a questionnaire with 15 English sentences containing 5 types of figures of speech (hyperbole, synecdoche, personification, metonymy and idiom) was sent to 31 translators from 4 translation offices in Shiraz to be translated. The participants were all allowed to use any kind ofdictionaries throughout the process. Next, the questionnaire was given to Google machine translation and finally, all of the collected translated sentences, whether by humans or Google, were assessed on the basis of Christopher Waddington's model of translation quality assessment, Method C, (2001) and compared with each other using t-tests.The collected data was input into SPSS. Then a series of descriptive and inferential analyses were conducted on the data based on the research question raised in the study.Having analyzed the data, the researcher observed that the overall figure of speech was higher in humans(31.38) than in Google (17.6). For hyperbole, synecdoche, metonymy and idiom components, the mean score obtained for humanswas higher than thatobtained for Google. In contrast, the interesting result was that the humanpersonification means score was lower than the Google.


Activities, conducted in the logistics sector, cont ribute to pollute the world. Especially, road transportation contaminates the environment wi th the release of exhaust emissions. Transport volumes as well as the proportion of the road sector are constantly rising, which intensifies its environmental impacts. In ord er to determine the main culprits of pollution, Environmental Impact Analysis (EIA) are used. These concepts are mostly ambiguous, fuzzy and hard to present in a comprehen siv way. The main purpose of the present thesis is to develo p an analysis in order to investigate the environmental impacts of road transportation al ong a certain supply chain. An academic resource was used as database, in order to develop and test an exhaust emission calculation in cooperation with a case com pany. Besides CO2, this assessment also focuses on the measurement o f other exhaust emissions like No x, PM or CO. Furthermore, economic factors like, cos ts caused per transport are calculated. Aspects, like capacity ut iliza ion, the use of environmentally friendly tires or eco-friendly driving styles, are included in the analysis. These factors influence fuel consumption and thus the final produ ction of exhaust emissions. A detailed description of each factor and calculation step is illustrated in this thesis. Due to a high complexity of transportation, this an alysis is limited to road transportation. The fundament of the analysis build s the categorization of crafts due to the Euro standards. Hence, just transports conducte with crafts, manufactured within the European Union, can be evaluated. A validation test and in-depth interviews were cond ucted in order to approve the practicability of the developed assessment. During this process, strengths and weaknesses of the analysis were identified. Finally , the analysis is critically examined by showing its application constraints as well as p ros ective development opportunities. An enlargement, to include other transport modes, m aterial handling activities in order to measure impacts during intermodal transportation al g a whole transportation chain, is a prospect outlook.


Emerging human rights are destined to modify, improve and transform a number of already traditional concepts so as to achieve greater guarantees and protection for the rights of individuals and collectivities. One of the big changes that will be brought about by the concept and conception of emerging human rights is that, following on from the processes of positivization, generalization, internationalization and specification, they represent the beginning of the fifth historical process in the consolidation of human rights, namely the process of interaction. A number of breakthroughs have already been achieved, such as the recognition of emerging biocultural rights in the recently adopted Nagoya Protocol on access to genetic resources and shared benefits.


Software-defined networking (SDN) enables centralized control of a network of programmable switches by dynamically updating flow rules. This paves the way for dynamic and autonomous control of the network. In order to be able to apply a suitable set of policies to the correct set of traffic flows, SDN needs input from traffic classification mechanisms. Today, there is a variety of classification algorithms in machine learning. However, recent studies have found that using an arbitrary algorithm does not necessarily provide the best classification outcome on a dataset, and therefore a framework called ensemble which combines individual algorithms to improve classification results has gained attraction. In this paper, we propose the application of the ensemble algorithm as a machine learning pre-processing tool, which classifies ingress network traffic for SDN to pick the right set of traffic policies. Performance evaluation results show that this ensemble classifier can achieve robust performance in all tested traffic types.


A new approach is proposed to describe the spinodal decomposition, in particular, in polymer binary blends. In the framework of this approach, the spinodal decomposition is described as a relaxation of one-time structure factor S(q,t) treated as an independent dynamic object (a peculiar two-point order parameter). The dynamic equation for S(q,t), including the explicit expression for the corresponding effective kinetic coefficient, is derived. In the first approximation this equation is identical to the Langer equation. We first solved it both in terms of higher transcendental functions and numerically. The asymptotic behaviour of S(q,t) at large (from the onset of spinodal decomposition) times is analytically described. The values obtained for the power-law growth exponent for the large-time peak value and position of S(q,t) are in good agreement with experimental data and results of numerical integration of the Cahn-Hilliard equation.


A study of the micromechanical damage behavior of asphalt concrete is presented. Asphalt concrete is composed of aggregates, mastic cement, and air voids, and its load carrying behavior is strongly related to the local microstructural load transfer between aggregate particles. Numerical simulation of this micromechanical behavior was accomplished by using a finite-element model that incorporated the mechanical load-carrying response between aggregates. The finite-element scheme used a network of special frame elements each with a stiffness matrix developed from an approximate elasticity solution of the stress and displacement field in a cementation layer between particle pairs. Continuum damage mechanics was then incorporated within this solution, leading to the construction of a microdamage model capable of predicting typical global inelastic behavior found in asphalt materials. Using image processing and aggregate fitting techniques, simulation models of indirect tension, and compression samples were generated from surface photographic data of actual laboratory specimens. Model simulation results of the overall sample behavior and evolving microfailure/fracture patterns compared favorably with experimental data collected on these samples.


A detailed paleomagnetic and rock magnetic record of the upper Kaena polarity reversal was determined from late Pliocene marine marls in southern Sicily. Two separate characteristic magnetization components were distinguished: a low-temperature (LT) component between 200° and 50°C and a high-temperature (HT) component between 500° and 580°–610°C. The two components record the reversal in a slightly different way, but both were acquired in an early stage following deposition, most probably by authigenic (biogenic) formation of magnetic minerals. The actual (R-N) reversal, via E and horizontal inclinations, seems to take 3.3 kyr and is followed by a stable normal interval (3.3 kyr) and subsequently by a significant excursion (50°–60°) in declination (3.6 kyr). Relative intensities were lower during a time-span of 5.6 kyr and show a minimum of 10% of the nontransitional values, but during the excursion, no intensity changes are apparent. The VGPs of the HT component are confined to a longitude between India and Australia; those of the LT component oscillate between this same longitude and one passing over North and South America. We conclude that most if riot all observed features are largely determined by the remanence acquisition process which is complicated by authigenic formation of magnetic minerals and cyclically fluctuating paleoredox conditions. This has not only resulted in considerable smoothing but also in delayed NRM acquisition in specific sedimentary intervals. We believe that the observed "excursion" is a sedimentary artifact and not related to geomagnetic field behavior during transitions. We emphasize that many reported "geomagnetic" features may in fact be due to the sedimentary remanence acquisition process.


This study sought to examine the extent to which household income level influences the dropout rate from day secondary schools in Murang'a East Sub-County. This study employed structural strain theory and school dropout and poor family socialization theory and drop outing. The study took pragmatic research philosophy and a descriptive research design to study the phenomena in Murang'a East Sub-County. Using questionnaires, data relating to socio-economic data were collected from about 300 dropouts from Murang'a East Sub-Sub-County who were selected using a convenient and snowballing sampling technique.  The research established that the level of household income has a bearing on secondary school dropout from Murang'a East Sub-County. The research concludes that secondary school drop outing has a significant drawback to the educational goals and objectives. Secondary school education continues to be a vital investment despite the challenge of drop out. Most of the students who drop out of secondary schools are social and economic reasons. The study recommends that the government should increase the allocations to the most vulnerable students. Also, the CBOs and NGOs to step in and offer such students the supply of social amenities such as sanitary towels. More efforts should be focused on sensitizing the importance of secondary school education and advocating for child labour to be dealt with fiercely.


When business owners play music in their establishments, they have either appropriately purchased a public performance license or they are playing the musical composition without permission from the rights holder, ultimately violating the Copyright Act. Business owners commonly use what is known as the Homestyle Exemption, giving them the ability to forego purchasing a license, assuming they can meet the exemption's requirements. Before the era of music streaming, terrestrial radio was the popular way to consume music, which is reflected in the Homestyle Exemption's requirement that the music be radio broadcast. Today's business owners are taking advantage of other music services on the market, services that would not fit under the provisions of the Homestyle Exemption. Congress specifically delineated terrestrial radio under this exception, because it believed allowing such usage within the business would not hurt an artist's record sales. Non-interactive streaming services should be similarly viewed. These services likewise are not detrimental to an artist's career, but achieve the same goals outlined by Congress in the Homestyle Exemption, and should be viewed as another way to consume music in the business under this exception.

The verification and validation (V&V) of agent-based models (ABMs) is challenging. The underlying structure of the model and the agents can change over time. Furthermore, the theoretical context of the model is often very different from established models of the same phenomenon. In an effort to overcome these issues, trace validation is becoming a common V&V mechanism within the agent-based modeling community. In trace validation, characteristics of agents and the model are tracked over time and then analyzed by subject matter experts (SMEs) to gain insight into unexpected and potentially invalid output. Here, we present our tool, the V&V Calculator, which applies predicates employed in the field of software engineering. The result is a structured trace validation approach with quantifiable measures that facilitates SME exploration and insight into the causes of unexpected output within ABMs.

Background: Pulsed fast/thermal neutron analysis(PFTNA) is an advanced bulk technique for non-destructive elemental characterization,which was applied to landmine identification in some advanced countries.Purpose: To demonstrate the feasibility of the PFTNA landmine detection method.Methods: A PFTNA landmine identification system was set up based on a millisecond pulsed D-T neutron generator and a LaBr3(Ce) gamma detector.Interrogative experiment was carried out on different landmines and distracters in the typical organic soils and inorganic soils.Results: The fast neutron induced spectra and the thermal neutron induced spectra of the samples were obtained successfully through time-sharing measurement circuit.The relative contents of 12C、16O、1H、14N contained in the objects were obtained through the analysis of the neutron induced spectra.Conclusions: It could be concluded that the PFTNA method can identify the landmines from the common distracters.


In vitro studies have demonstrated that insulin-like growth factor-1 (IGF-1) plays important roles in folliculogenesis, such as maintenance of survival after culture of caprine ovarian tissue (MARTINS et al., Animal Reproduction, v.7, n.4, p.349-361, 2010) and growth of isolated follicles in cows (GUTIERREZ et al., Biology of Reproduction, v. 62, p. 1322-1328, 2000). However, there is no report on the effect of different concentrations of IGF-1 on the in vitro development of ovine preantral follicles enclosed in ovarian tissue. Thus, the aim of this study was to evaluate the effect of IGF-1 on the morphology and activation in vitro of preantral follicles enclosed in ovine ovarian tissue. Ovaries (n=10) from adult mixed-breed sheep were collected at a local slaughterhouse and transported to the laboratory. The ovarian cortex was divided in fragments and one of them was immediately fixed and destined to histology (fresh control). The remaining fragments were cultured in vitro for 7 days in α-Minimal Essential Medium (α-MEM – GIBCO, Invitrogen, St Louis, EUA) supplemented with insulin, transferrin, selenium, hypoxanthine, glutamine, ascorbic acid and BSA (α-MEM+ - control medium) or in α-MEM+ added by different concentrations of IGF-1 (1, 10, 50,100 or 200 ng/mL). At the end of the culture, morphological analysis of preantral follicles was performed through histology, and they were classified as normal or atretic according to the absence of presence of cytoplasmic shrinkage, nuclear pycnosis and/or disorganization of granulosa cells, as well as classified as primordial or growing follicles (intermediate, primary and secondary follicles). The percentage of normal, primordial and growing follicles were compared by ANOVA and Tukey's test (P 0.05) were observed between α-MEM+ and IGF-1 concentrations. In comparison with fresh control, it was observed a significant reduction in primordial follicles and an increase in developing follicles in all treatments. Moreover, treatment with 100 ng/mL IGF-1 promoted higher (P < 0.05) follicular activation, compared to α-MEM+ . In conclusion, the concentration of 100 ng/mL IGF-1 maintained survival and promoted activation of ovine preantral follicles cultured in situ.


Part b) presents some issues that have emerged from the consultation on CICES this year and provides a reflection on how the feedback has been considered so far in the ongoing revision process of CICES. This is only an extract from a comprehensive review paper that is still to be finalised and represents current thinking. We would like to expose these issues for feedback by London Group members as part of the review process. The next steps will be a methodological comparison with the ES classification systems sponsored by USEPA (FEGS and NESCS) and discussion at an expert workshop in Wageningen on 17-18 November. The review paper and a proposal for CICES V5.0 are expected to be finalised by the end of 2016.


The appearance on August 1, 1918, of Eternidades, a collection of verso desnudo from 1916-1917, fullyjustified the success of El diario de un poeta reciencasado and validated Juan Ramon Jimenez' position as doyen of Spanish poetry. Even Rafael Cansinos-Assens, chronicling the turmoil of creacionismo, acknowledged the renovating spirit behind the book from an author essentially at odds with the Spanish vanguard: "Tan solo Juan Ramon Jimenez profiaba por evadirse de los alveolos de sus antiguas colmenas, llevando sus abejas a los nuevos claustros de rota arquitectura en Eternidades."2 Three of the first five pieces in Eternidades are metapoems: "Accion," ";lntelijencia, dame," and "Vino, primero, pura."3 Their presence initiates a period in Juan Ramon's work in which, like Mallarme and Valery, he will expend creative energy turning into poetry deliberations on the act of poetry. The first metapoem is simply a healthful recognition of fluidity and apprenticeship, with possible overtones from romanticism about the weakness of words: "No se con que decirlo / porque no esta hecha todavia mi palabra." The third poem's dance of the veils-"Vino, primero, pura"-enjoys' the privilege of being a set piece in contemporary Spanish poetry. By contrast, "ilntelijencia,


Summary: We evaluated prospectively the occurrence of seizures within 15 days of a first stroke or transient ischemic episode in 1,640 patients to study relation between seizures and type of stroke. Seizures occurred in 90 patients (5·4%), including 36 (4·4%) of 814 with infarct owing to atheroma, 21 (16·6%) of 126 with infarct owing to cardiogenic embolus, 3 (1%) of 273 owing to lacunar infarct, 5 (1·9%) of 259 owing to transient ischemic attack (TIA), 21 (16·2%) of 129 owing to supratentorial he matoma, and 4 (16·6%) of 24 owing to subarachnoid hemorrhage. Thirteen (14·6%) of 89 subcortical infarcts were associated with seizures. Seizures were the initial sign of stroke in 80 (89%) of 90 cases and were usually single and partial. Seizure symptoms were most often motor, sensory, or visual.

Faced with the prospect of its adversaries mitigating its long-held superiority in sophisticated weapons systems, the US announced in 2014 that it was about to embark on a 'third offset strategy' in order to maintain its military-technology edge. In its quest to harness new technologies and operational concepts however, the third offset strategy is likely to raise important questions for Europe and NATO. Daniel Fiott addresses some of the major issues at hand related to alliance politics in NATO and some of the potential defence-industrial effects.


A compressor has a control valve that adjusts the pressure difference between a crank chamber and a cylinder bore for controlling the inclination of a drive plate. The control valve protrudes outward from the compressor housing. The compressor also has a support protruding outward from the front housing and a leg protruding outward from the cylinder block. The outer ends of the support and the leg extend further from the compressor than the furthest extremity the control valve. Therefore, when the compressor is placed on a flat surface, the support and the leg prevent the control valve from contacting the surface. This protects the control valve from damage during transport and handling.

In 32 patients with RA before and after lymphocyto- and/or plasmapheresis the authors determined the content of high molecular protein fraction (macroproteins) in the blood plasma. In the consecutive analysis of the body response and procedure effects it was found out that decrease in the level of macroproteins correlated with the changes of immunological status and state of the patients. The index of macroproteinemia can be used for quantitative assessment of plasmacytopheresis effect.


The forests of China are grouped into five types according to the classification system used in The Vegetation of China. The forest biomass and net primary productivity (NPP) in different climatic zones are calculated. Furthermore, the biomass and NPP of different plant organs are also analysed. The results show that forest biomass and NPP increase with the temperature, i.e. cold temperate zone temperate zone subtropical zone tropical zone. In general, the biomass of natural forests is larger than that of artificial forests. But artificial forests have larger NPP than natural forests except those in tropical zone.

"Saffar, how many push-ups can you do in 10 seconds?" "I'll show you, T2." With that exchange, Saffar proceeded to do 15 push-ups as T2 (Terrence Toepker) did the timing. "I think that the upper limit is set by physical principles and not by your strength." Assuming that you cannot pull yourself down by grabbing the floor, the shortest time down is caused by gravity acting alone. A simple physics model for this situation could be a straight, uniform plank pivoted at one end that oscillates up and down due to an elastic reflecting impulse that occurs instantaneously at the down position, shown in Fig. 1(a).


Hydroxyproline is oxidized by sodium peroxide, if copper or cobalt is present, to give an unstable red chromogen which, in hot acid solution, can be condensed with isatin to form a stable red complex. The conditions are described which permit the direct application of this reaction to the quantitative estimation of hydroxyproline in acid or alkali hydrolyzates of gelatin. By this method moisture-free gelatin is found to contain 14.65% of hydroxyproline.


Throughout the years, a large number of paintings by Perugino have been investigated using the in situ non-destructive x-ray fluorescence (XRF) technique. Three anomalous characteristics were frequently identified, concerning a brown earth pigment containing zinc, the presence of manganese in some red lakes and the association of the presence of copper and tin with grey–blue regions. In an effort to understand these anomalies better, five micro-samples, taken from selected easel paintings by Perugino at the Galleria Nazionale dell'Umbria and a fresco at the Monastero di Sant'Agnese in Perugia, were studied by micro-Raman spectroscopy and scanning electron microscopy (SEM). Micro-Raman spectroscopy was a useful tool to investigate the molecular nature of such uncommon pigments and SEM provided useful information on the stratigraphy of the paint layers. The brown earth pigments, used by the master in the last period of his production, were definitely confirmed to be characterized by zinc impurities. The manganese contained in red lakes was shown to be due to ground alkaline glass, with a small quantity of manganese and iron, probably added to the oil binder in an attempt to speed up drying. Finally, in the sampled paintings, the grey–blue colour characterized by copper and tin was not present. Copyright © 2004 John Wiley & Sons, Ltd.


The study was aimed at using waste-soil fungi for production of cellulase enzyme. Fungi were isolated from soil samples obtained from Odo-Aremu dumping sites in Ado-Ekiti, Nigeria. Three fungal species namely Aspergillus niger, Aspergillus flavus and Trichoderma spp. were isolated. The fungal isolates were assayed for their ability to produce cellulase enzyme as well as variable conditions that suited the production of the enzyme. Temperature, days of incubation and pH of assay medium were all significant in the enzyme production. Varied chaff concentrations however had no significant influence on enzyme production. All three isolates showed cellulase synthesis best 8 days after incubation at 37 o C and enzyme activity was assayed to be best at 45 0 C. Enzyme synthesis was also assayed to be best at oatmeal chaff concentration of 3% and enzyme activity was best between pH 4-7. Keywords: Cellulase, Oatmeal chaff, dumpsite, enzyme activity, Aspergillus, Trichoderma


This study was carried out investigation of characteristics palace gardens representing historical background, political and cultural identity in Korea, China, and Japan. It had been done a comparative analysis in formation, location and site layout, site composition, landscape elements and planning, landscape technique and vista for palace gardens in East asia's three countries. In order to process this study, Changdeokgung Palace in Korea, Summer Palace in China and Sento Imperial Palace in Japan were selected based on similar status. therefore it provide theoretical foundation to investigate the identity of palace gardens in three countries. Furthermore the study determined homogeneity(similarity) and heterogeneity(differentiation) of the characteristics between palace gardens in three countries through the in-depth comparative analysis in order to investigate identity of palace gardens in three countries and to present the value of Korean palace garden. Homogeneity and heterogeneity between palace gardens in three countries deducted from the study were summarized as follows; First, it shows indigenous style of Korean garden throughout adapting natural terrain without natural destruction. Second, various symbolic elements which ie reflected East asian ideologies present in the gardens. Chinese thoughts and technique were influenced in the development of palace garden in Korea and implemented in similar ways of China. Homogeneity of utilizing waterscape could be found in three countries. Lastly, Palace garden in Changdeokgung had played a role as cultural place with taste for the arts rather than representing authority of the throne. It appears to be similar in China and Japan. The reason how Korea, China and Japan established their own independent style is that each palace garden had been developed to embrace indigenous culture with introduced elements even though they were closely bound up with culture.5)

Invariant manifolds of equilibria and periodic orbits are key objects that organize the behavior of a dynamical system both locally and globally. In slow-fast systems, that is, systems with sets of variables that evolve on two different time scales, there also exist so-called slow manifolds, along which the flow is very slow compared with the rest of the dynamics. Slow-fast systems are often found in various applications, including models for nerve conduction, physiological models, chemical models, ecological models and climate models, and slow manifolds play an important role for the overall dynamics. In particular, slow manifolds are known to organize the number of small oscillations of what are known as mixed-mode oscillations (MMOs). For slow-fast systems in R with two slow and one fast variables, slow manifolds are surfaces that can be either attracting or repelling, and intersections of two slow manifolds of different types are known as canard orbits. In addition, slow manifolds are locally invariant objects that may interact with invariant manifolds of equilibrium and periodic orbits, which are globally invariant objects. Such interactions may produce complicated dynamics about which only little is known from a few examples in the literature. This thesis focuses on such interactions in a slow-fast system with one fast and two slow variables. We present a numerical approach that allows for the systematic detection of canard orbits and intersections between other manifolds. The aim is to understand the consequences of the interaction between a global invariant manifold and a slow manifold for the overall dynamics in a slow-fast system. Specially, we study the generic situation of a quadratic tangency between the unstable manifold of a saddle-focus equilibrium and a repelling slow manifold. This scenario occurs in a system where the corresponding equilibrium undergoes a so-called supercritical singular Hopf bifurcation. We compute these manifolds as families of orbits segments with a two-point boundary value problem setup and track their intersections, referred to as connecting canard orbits, as a parameter is varied. We describe the local and global properties of the manifolds, as well as


Fermentation medium of thermophilic fungal for xylanase production was optimized by response surface method and the basic properties of the enzyme solution were studied. First,eight kinds of factors of the initial medium was adopted by the Plackett-Burman design,and selected three kinds of important factors,namely,corn cob,urea and KH2PO4,and then the path of steepest ascent was adopted for the central composite experiment to determine the maximum response interval. Finally response surface optimization results was obtained,corncob 4.570%(w/v) ,urea 1.797%(w/v) ,KH2PO4 0.497%(w/v) ,therefore,enzyme activity was increased by 18%. The enzyme pecificity was better,corncob being regard as substrate,the optimal enzyme reaction temperature was 65℃ and the temperature was more stable,the optimum pH 6.8 and pH stability was better.


Laguerre filters have infinite impulse responses (IIRs) but with finite tapped delay-line parameterizations. This paper investigates subspace-based blind identification of Laguerre filter tap coefficients, the internal filter state, and the input, given only noisy observations of the output. This paper deals only with single-input, multiple-output (SIMO) Laguerre models. A state space model for the SIMO Laguerre system is derived from which blind estimation algorithms are developed. As in the finite impulse response (FIR) case, the Laguerre filter taps coefficients can be estimated from the column space of a certain Hankel matrix constructed from noisy output observations, whereas the internal state and input can be estimated from the row space by exploiting state space structure. While not exactly uniquely identifiable, conditions are given for which the tap coefficients, the internal state, and the input can be determined to within a multiplicative scalar factor.


Purpose

The purpose of Part II of this two-part paper is to uncover important differences in the nature of the three unlearning subprocesses, which call for different leadership interventions to motivate people to move through them.

Design/methodology/approach

The paper draws on research in behavioral medicine and psychology to demonstrate that initial destabilizing of old patterns and the subsequent behavioral processes of discarding the old and experimenting with the new are qualitatively different.

Findings

Leadership interventions must fit the unique requirements of each unlearning subprocess. Discarding old routines requires continued focus on the costs of not doing so, as well as a progressive refocus on positive possibilities and engaging people in activities to explore them. When aspects of the old routine resurface, the costs of relapse must again become salient, leading to further discarding-from-use, followed by further positive experimentation. Finally, maintaining long-term release of an embedded routine requires recognition of the emerging new patterns and a shift from future-oriented visioning of possibilities to current satisfaction with the new.

Originality/value

All empirical studies of organizational unlearning imply some form of destabilization of old learning as an antecedent to unlearning, and many of them discuss subsequent behavioral and cognitive displacement. However, they have not clearly distinguished between these subprocesses to fine-tune how to motivate people to move through them. This paper addresses that gap.


Cereals are the basis of human nutrition. Barley (Hordeum vulgare L.) is globally the forth most important cereal and among the top ten crops with regard to production and acreage [128]. There are special requirements for protein content and quality in barley grain, depending on the use for malt production or as animal feed. The mechanisms controlling the accumulation and composition of grain protein are not completely understood yet. This thesis aims to further the understanding of the processes that affect the accumulation of carbon and nitrogen in the endosperm in the early stage of its development on a whole-plant level. By being embedded in a systems biological project the obtained data will help to establish a model, which can predict the effects of genetic manipulations in endosperm metabolism on grain yield and composition. The Cand N allocation was examined at 8, 14 and 20 days post anthesis (dpa) in the barley cultivar Bomi` and the low-starch mutants Riso 16 as well as Riso 13 in pot experiments under controlled environmental conditions. The endosperm was in the focus of interest. Therefore the composition of its protein was determined at 14 and 20 dpa by fractionation in albumins/globulins, hordeins and glutelins. Furthermore the contribution of current C-and N assimilation to endosperm development was investigated by employing Cand N in vivo double puls-labelling of whole plants. The C content in the vegetative organs was constant during the investigation period and no differences between the genotypes were observed. Thus no C remobilisation occurred. On the other hand a mobilization of nitrogen in the vegetative organs was proved for Bomi` and Riso 16, although to a different extent. The decreasing N content in the shoot of Bomi` and the leaves of Riso 16 correlated with the N increase in their endosperms. The fresh weight of the endosperms was increasing linearly between 8 and 20 dpa without any genotypical differences. The progress of dry weight was very similar, but 20 dpa it was on average 17 % lower for the mutants compared to Bomi`. This shows the lower ability to accumulate dry matter in the endosperm of Riso 16 and Riso 13 although the sink capacity was comparable to Bomi`. Incorporation of currently assimilated C und N in the endosperm increased during

Recent research has demonstrated the superiority of SVM-based approaches for offline cursive character recognition. In particular, Camastra's 2007 study showed SVM to be better than alternative LVQ and MLP approaches on the large C-Cube data set. Subsequent work has applied hierarchical vector quantization (HVQ) with temporal pooling to the same data set, improving on LVQ and MLP but still not reaching SVM recognition rates. In the current paper, we revisit Camastra's SVM study in order to explore the effects of using an alternative modified direction feature (MDF) vector representation, and to compare the performance of a RBF-based approach against both SVM and HVQ. Our results show that SVMs still have the better performance, but that much depends on the feature sets employed. Surprisingly, the use of more sophisticated MDF feature vectors produced the poorest results on this data set despite their success on signature verification problems.
