Organization theorists have begun to draw on developments in complexity theory to redirect the literature on organizational transformation and strategic change towards notions of emergence. Useful contributions have been offered on the ways in which emergent order arises from the repeated application of simple sets of order generating rules in so called complex adaptive systems. This paper explores the nature of such (organizational) order generating rules and the ways in which they shape transformation processes. The authors adopt a mode 2 approach, operating at the interface of organization science and design methodology. First, a complexity based framework for organizational change is described, suggesting that transformation can be viewed as an emergent process, accessed and influenced through three interacting gateways – order generating rules, far-from-equilibrium conditions and feedback processes. This framework is used to examine two cases of organizational change. The paper then proceeds to compare these cases and theorize about the nature of rules. Finally, rules are considered in terms of how they arise as well as their objects, and a number of propositions for further research are suggested.


The paper presents prospective study of the 274 children from 3 to 14 years old suffered from bronchitis with long cough. Two hundred three patients (74%) had atypical infection. We distinguished group with a high risk of atypical infection by analyzing clinical, laboratory, immunological features of respiratory Chlamydia and Mycoplasma infection in children.


Purpose: Low Molecular Weight Cyclin E (LMW-E) are the oncogenic forms of cyclin E and were originally discovered in breast cancer (BC). LMW-E are generated from N-terminal cleavage of the 50 KDa, full-length cyclin E1 (FL-cycE). Our laboratory has established that LMW-E expression (i) correlates with poorer survival in BC patients; (ii) increases in frequency as BC progress from ductal carcinoma in situ to invasive ductal carcinoma; (iii) drives spontaneous and metastatic BC in murine transgenic models; (iii) causes human mammary epithelial cells (hMECs) to transform in vitro and form tumors in vivo. Elucidating the critical oncogenic functions and essential downstream factors of LMW-E is a current void in the field and may have important therapeutic implications. Experimental Design: Immunohistochemistry (IHC) analysis were performed using tumor specimens (n=725) from breast cancer patients diagnosed with Stage 1 or 2 disease to determine the level of LMW-E. Micro-dissected tumor DNA from these tissues were analyzed for copy number variations (CNVs) using Molecular Inversion Probe (MIP) based arrays. CCNE1(encoding Cyclin E1) knock-out 76NE6 and 76NF2V hMEC lines were generated by CRISPR, followed by transfection of lentivirus vector expressing doxycycline inducible EGFP fused LMW-E or FL-cycE. Time-lapse live cell imaging was performed to monitor the cell growth and phenotypes after induced expression of LWM-E or FL-cycE. DNA replication and replication stress were examined by BrdU labeling and immunofluorescent (IF) assays using antibodies against BrdU and Replication Protein A (RPA). IF for gamma-H2AX and western blotting for phosphor-RPA32, ATR-CHK1 and ATM-CHK2 pathways were performed to determine the DNA damage and responses. Results: Analysis of CNVs for the 725 tumors stratified by the cyclin E phenotypes reveal that the frequency of the CNVs (gains & losses) were the most significant in patients whose tumors expressed LMW-E and were predictive of poor prognosis independent of BC subtypes. DNA damage signals including gamma-H2AX foci and phosphor-CHK1 were similarly enhanced in hMECs induced for FL-cycE or LMW-E over-expression. Different effects of FL-cycE and LMW-E on DNA replication and replication stress were observed. Induced FL-cycE overexpression attenuated increased RPA foci and RPA phosphorylation, inhibits DNA replication and cell growth, and ultimately lead to cell death. LMW-E overexpression facilitated DNA replication and cell proliferation with damaged DNA, resulting in multi-nuclei and micro-nuclei formation in daughter cells. Conclusion: LMW-E expression positively correlates with genomic instability in BC samples. LMW-E facilitates hMECs to by-pass replication stress induced tumor barrier and survive with damaged DNA, resulting in abnormal nuclei formation, an oncogenic phenotype.

This article points out the advantage of open fund through the comparision between open fund and closed fund. It also emphasizes this kind of fund to be applied as soon aspossible in our country because of its stimulating function in national economic development.


Our task is to form citizens who will no longer be willing to sell their birthright for a mess of pottage (Heb 12:16), citizens who will believe God instead of the world, who will trust God instead of the world, who will serve God instead of the world. We must create a culture in which lies, subterfuge, and empty materialistic promises cannot move sufficient numbers to support worldly power without forcing the state to reveal itself in a blatant show of force. In the Church herself, we must create a culture in which the first recourse of all will be a recourse to Christians, in which collaboration with evil will be considered a betrayal of Christian responsibility, and in which persistent public collaboration with evil will result in exclusion from communion with Christ.


The Navy is supporting a research effort to develop a shipboard plasma arc waste destruction system. It is the goal of this program not only to process the tons of waste generated daily aboard large surface combatants such as aircraft carriers, but also to meet the unique operating requirements imposed on shipboard equipment. While the design was specifically developed for Navy warships, many of its features would also be advantageous for use with commercial vessels. These attributes include lower labor requirements, modular design for ease of installation in existing compartments, fast startup and shutdown, and a lightweight and compact thermal destruction unit. In this paper, we will discuss a new design concept for plasma-assisted thermal destruction equipment and the basic requirements for operating the thermal destruction equipment at sea, as well as describe the components of the fullscale demonstration that is currently underway.


A multicultural society should possess the characteristics of a society in which different ethnic groups live together but with no interaction. The minority groups living therein are passively tolerated without being accepted by the majority group. An intercultural society should be defined as a society in which different groups live together and exchange their life experiences with mutual respect for their different styles of life and values. That is why a correct starting definition of interculturalism would be that interculturalism is a critique and an alternative to multiculturalism. It is possible for the members of different cultures to live close to each other and that is the most crucial characteristic of multicultural societies. An intercultural society represents a society in which we live and create not close to each other but with each other and for each other.Accordingly, the contemporary Balkan society is facing the process of its transition from the multicultural into the intercultural one, that is, the process of spreading and adopting the idea and practice of interculturalism in a multicultural community. More precisely, this implies the development of the concept of a cultural and educational policy that would foster appreciation of cultural diversity and lead to the creation of a society in which different cultures interpenetrate.At the end of the paper the measures of the public cultural politics of the Balkan countries aiming at improvement and advancement of the existing intercultural dialogue are summed up.


This paper shows results of simulation investigations of wind turbine with doubly-fed induction generator operation in unbalanced electric power system. The aim of presented research was analysis of impact of network events on the wind power plant mechanical system. In order to realize the investigations a dynamic mathematical model of wind power plant has been created. The model allows for mechanical system of power plant, rotor-side electronic power converter, slip-ring machine and control system. The transmission and the turbine have been modeled as a six mass oscillator reduced to the generator shaft. The study results show that voltage unbalance and short-term voltage dips cause torque surge on the shaft and transmission of the wind power plant. A modification of method of active power control has been proposed in order to reduce the im- pact load of the mechanical system. The results of simulations of wind power plant transients with modified control system are quite promising: a reduction of impact load of mechanical system up to 72% has been reached.


The house discovered about ten years ago in Uthina contains two sets of remarkably well-preserved latrines. The first complex,consisting of three-seat latrines, was likely  exclusively used by  the inhabitants of the domus. The second one is formed of seven-seat latrines inserted in niches. These latrines, although part of the house, are only accessible from the street along the facade of the house. Their encroachment on public streets, the large number of seats and their planimetric location all favour semi-public or even public use.


Over the past years an always growing interest has arisen about the measurement technique of time-correlated single photon counting (TCSPC) and many applications exploiting TCSPC have been developing in several fields, such as medicine and chemistry. The use of multianode PMTs and of single photon avalanche diode arrays led to the development of acquisition systems with several parallel channels, to employ the TCSPC technique in even more applications. Since TCSPC basically consists in the photons arrival time measurement, the most important part of an acquisition chain is the time measurement block, which must have high resolution and low differential nonlinearity and, in order to implement multidimensional systems, it has to be integrated to reduce both cost and area. To accomplish all these specifications, we have designed and fabricated a 4 channel fully integrated time-to-amplitude converter (TAC), built in 0.35 μm Si-Ge technology, characterized by a variable full scale range from 11 ns to 89 ns, very good time resolution (better than 20 ps FWHM), low differential nonlinearity (better than 0.04 LSB peak-peak and less than 0.2% LSB rms), high counting rate (16 MHz), low and constant power dissipation (50 mW) and low area occupation (340 × 390 μm2 per channel). Our measurements also show a very little crosstalk between converters integrated on the same chip; this feature together with low power and low area make the fabricated converter suitable for parallelization, so that it can be the starting point for future acquisition chains with a high number of parallel channels.

The imaging photopolarimeter on the Pioneer 10 Asteroid-Jupiter probe is being used to measure starlight and zodiacal light during the cruise phase of the mission. The 2.5-cm-diam telescope is used with a 2.3 deg field of view to spin/scan the sky in the region between 10 and 151 deg from the direction of motion of the spacecraft. Orthogonal components of brightness are measured in two wavelength bands: blue (3900 to 5000 A) and red (5950 to 7200 A). The gegenschein was observed on Mar. 14, 1972, when the earth-sun-spacecraft angle was 3.4 deg and the spacecraft was 9.2 million km from the earth and 1.011 AU from the sun. The distribution of brightness relative to the antisolar point is similar to that obtained from ground-based observations. Taken together, these results show that the gegenschein is not associated with the earth.


This paper describes a general architecture for mechanisms of attention control in discourse. The proposal is based on a generalized notion of salience that ab stracts from existing, theory-specific definitions of entity salience. I consider two dimensions of salie nce, hearer salience indicating the status quo or "givenness" of an entity, and speaker salience underlyin g the attempts of the speaker to manipulate this status. This framework is applied to three phenomena in the encoding of discourse referents, choice of referring expressions, word-order preferences, and ass ignment of grammatical roles. The adequacy of this proposal is illustrated by providing reconstructio ns of two theories, Givón's topicality approach and different instantiations of Centering. The proof for Ce ntering-adequacy is sketched, and the framework is compared to related proposals, with particular cons ideration of the optimality-theoretic Centering reconstruction by Beaver (2004). As a result, a parameterized architecture for modeling ling uistic variability in discourse is presented. It provides a powerful, simple and intuitive mechanism to in tegrate cognitive-pragmatic aspects of coding preferences in the field of natural language generation (NLG ). 1 Mechanisms of attention control It had been noticed very early that the choice among syntacti cally well-formed expressions is by no means determined by semantic constraints alone. Consider the fol lowing classical text (Grosz et al. 1995, ex. (5), shortened) with possible truth-semantically equivalent v ariations as illustrated in (4'), (1') and (5'): (1) Terryte really goofs sometimes. (2) Hete wanted Tonyto to join him on a sailing expedition. (3) Hete called himto at 6AM. (4) Tonyto was sick and furious at being woken up so early. (5) Heto told Terryte to get lost and hung up. (6) Of course, Terry te hadn't intended to upset Tony to. Here, I concentrate on referring expressions, in particula r on three interacting levels of variability. Note, that for this exemple text, the textual function of the alter natives is roughly identical to that in the original examples. choice of referring expressions (REF) (4') This guyto was sick and furious at being woken up so early. assignment of word-order preferences (WO)e.g. topicalization (1') Sometimes,Terryte really goofs. assignment of grammatical roles (GR)e.g. passive vs. active clauses (5') Terryte was told to get lost andTonyto hung up.


Objective: To evaluate in vitro the tensile bond strength of four resin cements in primary teeth.
Method: Thirty-six primary molars were selected and embedded in chemically activated acrylic resin with the test surfaces turned to the matrix. All specimens were prepared in the same way and were randomly assigned to 4 groups: Group 1: Single Bond adhesive system + Dual Cement, Group 2: Single Bond adhesive system + Rely X, Group 3: Single Bond adhesive system + Rely X Luting Cement, Group 4: Adhesive system proposed by the manufacturer + flowable Concise resin. The bond strength data were subjected to analysis of variance to verify the occurrence of significant differences among the surfaces and among the groups. The homogeneity of the variances was demonstrated by the Levene test. The Anderson-Darling test was used to analyze the normality of residues and the Tukey's multiple-comparison test was used to evaluate the differences among the groups.
Results: Group 2 presented the highest mean and the highest variability. Groups 3 and 4 presented close means and Group 1 presented the lowest variability. Group 2 presented the highest bond strength followed by Group 1. Groups 3 and 4 presented similar bond strengths and significantly lower than those of Groups 1 and 2.
Conclusion: There was difference only for the mean bond strength, which was higher in Group 2.


A quantum theory of line shape in pressure-induced absorption giving relatively simple results in closed form is developed. A flexible model correlation function satisfying certain general criteria is chosen and incorporated in a general quantum theory of absorption. Relations are derived for estimating the values of the time parameters in the correlation function in terms of known molecular parameters. The theory is applied to far infrared spectra: the translational spectrum of He–Ar, the well resolved S(0) rotational line of H2 at 77 K, and the unresolved rotational band of N2. In all cases, the theory fits the spectra and accounts for the spectral features.


Light signaling can affect root development and plasticity, either directly or through shoot-root communication via sugars, hormones, light, or other mobile factors.


The utility model discloses a vibrating disc, and particularly relates to a vibrating disc for automatically reversing materials. The vibrating disc comprises a chassis, a housing and a spiral transmission rail arranged in the housing; a feeding opening of the spiral transmission rail is communicated with the chassis; the chassis is arranged on the bottom end of the housing; a material separating piece is arranged on the spiral transmission rail; the material separating piece is connected with a reversing rail; and the discharging end of the reversing rail is joined to the spiral transmission rail. When the vibrating disk is working, the material separating piece carries out the material separation for materials failing to satisfy requirements, and then the reversing rail is reversed to be joined to the spiral transmission rail, so the materials failing to satisfy the requirements are prevented from entering the chassis and being loaded. The beneficial effects of the vibrating disc are that automatic material reversing is achieved; loading efficiency is high; and it is better ensured that production work is normally carried out.


The rapid expansion of multi-national companies and the formation of international monopoly capital are the micro-foundation and macro-condition of economic globalization respectively. These two promotes the process of economic globalization. Yet, as the nature of capital is the pursuit of maximum profit, capital expansion leads to the globalization of capitalist production relations. So in nature economic globalization is still the outcome of the global development of capitalism.

Objective To compare the diagnostic value of molebdenum target X-ray and MRI in breast carcinoma,so as to improve the detective rate of breast carcinoma.Methods The molebdenum target X-ray and MRI features in 36 breast carcinoma patients confirmed with histopathology were analyzed retrospectively and compared with the corresponding findings of histopathological results.Results The diagnostic accuracy of molebdenum target X-ray and MRI were 80.55%(29/36) and 88.88%(32/36),respectively;the combined accuracy was 94.44%(34/36),which was significantly superior to the single molebdenum target X-ray or MRI(P 0.05).Conclusion In view of its simple operation and sensitive to the microcalcification,molebdenum target X-ray should be the first choice in diagnosis of breast carcinoma.Likewise,the minute structure changes of breast carcinoma could be clearly demonstrated with MRI,the combination could improve the detective rate and accuracy significantly.


The paper presents a study of a power electronics device, based on a series resonant circuit with a parallel loaded capacitor. Two circuits are reviewed in consideration: a Buck DC-DC converter and a resonant parallel-loaded inverter. The difference between the two circuits is only in the relationship between the switching frequencies and the resonant frequency. In the first case, the operating frequency is equal to the resonant, and in the other case, the control frequency significantly exceeds the resonant tank frequency (at least over 2-3 times). The main purpose of the manuscript is to present the influence of the tolerances of the resonant elements on the operating modes of devices that share the same topology. This way, an assessment is made of the dependence of the output indicators on the tolerances and, accordingly, how to look for solutions to ensure the output parameters.


In this paper, we describe a device structure and optical design for a CMOS image sensor with the phase-difference detection photodiodes (PD) for an autofocus (AF) function. This image sensor has a pixel separated into two PDs by a PN junction. All the effective pixels function as both the imaging and the phase-difference detection AF (PDAF). We have realized a low dark random noise (=1.8eat 1PD, 2.5eat 1pixel) and high sensitivity (=78,000e-/lx sec at 1green pixel) image sensor with the imaging and the PDAF functions in all the effective pixels. Introduction Recently, image sensors with the PDAF function at image plane has been developed [1], [2]. These realize the AF function by arranging exclusive pixels to detect the phase-difference. In these image sensors, a pair of partially light shielded PD is arranged in a part of pixel array. The focusing speed is extremely fast in comparison with conventional contrast detection AF. The sensitivity, however, is degraded by the light shielding structure and interpolation processing by neighboring pixels is necessary for image generation [2]. Therefore, the number of pixels for AF function is limited to avoid the deterioration of image quality. In this work, we developed an image sensor with the imaging and the PDAF functions in all the effective pixels without exclusive pixel for AF function. All the effective pixels have two PDs each to detect phase-difference in one pixel without partially light shielding structure. Therefore, one pixel works as one AF point, and the sum of two PD outputs equals one pixel output. Fig. 1: Principle of the PDAF function Principle Fig. 1 shows the principle of the PDAF function. Exit pupil of an optical lens and a PD of the image sensor are in optically conjugate relation by on-chip micro-lens (ML). Therefore, each pixel by separating into two PDs has the pupil split function for the PDAF function. A light flux which passes through a right half of the optical lens is led to the PD-A (the PD at left si of the optica side). Defocusing between th provided fro image-B (th The directi image-B is and the back These mea lens is drive defocusing a

Antibacterial activity of zinc oxide (ZnO) or strengthening of hydroxylapatite whisker (HAPw) had been studied and applied widely. However, antibacterial property of ZnO-HAPw was scarcely researched nowadays. The aim of this study was to further investigate several kinds of morphologies of ZnO-HAPw prepared by sol-gel technology at different pondus hydrogenii (pH) value and temperature. Four kinds of morphologies of ZnO-HAPw were granule, triangle, short rod and gongs nail at 70°C and pH=6.4, 37°C and pH=6.6, 70°C and pH=6.6, 70°C and pH=6.6. The SEM images of HAPw and ZnO-HAPw samples showed that the HAPw surface was smooth and no difference after annealing treatment. In addition, different shapes of nanoZnO fused uniformly on the HAPw surface. The EDS indicates nanoZnO fuses on HAPw surface.


One of the most useful agents introduced for topical dermatological therapy in the past 20 years has been hydrocortisone (Cortef, Cortril, Hycortole, Hydrocortone) and some of its derivatives. There are currently well over 50 marketed topical preparations which contain one of these adrenal steroids. It would be a fair guess that 10 million containers of steroids were dispensed last year for the topical treatment of skin diseases, not to mention countless pills, solutions, and suspensions of steroids for oral, intramuscular, intravenous, and intracutaneous administration. The vast majority of patients with skin diseases who receive steroids use the steroids in topical preparations. The topical use of steroids has been of great advantage. Used in this way, there are rarely any systemic side-effects, and the patient requires far less supervision than when the steroids are given orally. As with any other disease for which steroids are used, skin diseases are controlled but


Summary form only given. Electrical biasing of the plasma is used on the TdeV tokamak to improve the divertor impurity confinement and exhaust pumping capability two important issues for fusion research. Plasma biasing, applied through the divertor neutralization plates, strongly affects the plasma properties in the scrape off layer (SOL), modifying the plasma potential, the edge density profile, and ion flow in the SOL. The ExB flow, associated with the radial electric field established near the separatrix, increases impurity transport into the divertor. Biasing greatly increases the efficiency of the divertor. There is a linear dependence of divertor pressure on the bias voltage, negative biasing having the strongest dependence. For negative biasing, divertor pressure is a nonlinear function of plasma density. Negative biasing also increases impurity retention in the divertor.


In series of three experiments young women's attention patterns were analyzed using eye tracking to deteremine the most effective viewing format and message content for presenting osteoporosis prevention ads. In Experiment 1A ads including both images and text attracted more attention than the image-only or text-only formats, p < .01. Experiment 1B revealed that osteoporosis ads attract significantly less attention than fashion and beauty ads (p < .01) and exercise apparel ads (p < .01). The last experiment revealed that osteoporosis ads featuring exercise messages were more effective at capturing attention than those promoting increased calcium and vitamin D consumption (p < .01). These findings may inform the way in which future osteoporosis prevention ads are created.


BACKGROUND
The measured intra-arterial volume of cadaveric ophthalmic arteries was used for safety recommendations during facial soft tissue filler injections. However, its clinical practicability and model applicability has become questionable.

OBJECTIVES
To measure the volume of the ophthalmic artery in living individuals by utilizing computed tomography (CT) imaging technology.

METHODS
A total of n = 40 Chinese patients (23 males, 17 females) were included in this study with a mean age of 61.0 (14.2) years and a mean body mass index of 23.7 (3.3) kg/m2. Patients were investigated using CT-imaging technology to evaluate the bilateral length, diameter and volume of the ophthalmic artery as well as the length of the bony orbit resulting in a total of n = 80 investigated ophthalmic arteries and orbits.

RESULTS
Independent of gender, the average length of the ophthalmic artery was 80.6 (18.7) mm, the calculated volume of the ophthalmic artery was 0.16 (0.05) cc and the minimal and maximal internal diameter of the ophthalmic artery was 0.50 (0.05) mm and 1.06 (0.1) mm, respectively.

CONCLUSIONS
Considering the results obtained from the investigation of n = 80 ophthalmic arteries it needs to be concluded that current safety recommendations must be re-evaluated. The volume of the ophthalmic artery seems to be 0.2 cc rather than 0.1 cc as previously reported. In addition, it seems to be not practical to limit the volume of soft tissue filler bolus injections to 0.1 cc due to the aesthetic requirements of each individual patient and treatment plan.


Abstract This paper examines the planned externalisation of affordable workers housing under Delhi's ongoing extended urbanisation. Drawing upon recent literature on planned illegalities, subaltern urbanisation, and agro-urban transformations in India and specifically in the Delhi region, the paper proposes tenement towns as a relational settlement category to understand the planned externalisation of housing. It examines three manufacturing clusters spread over an extensive territory in the DMIC urban corridor running out of Delhi. Finding evidence for how the workers housing is externalised into spaces marked as 'rural outsides' in the masterplanning documents. It examines the role of parallel agrarian institutions and social structures in enabling the illegal growth of the tenement towns. Finally, the paper critically examines the role such settlements play in maintaining a permanently temporary surplus workforce crucial for cheap global manufacturing. Through introducing tenement towns as a relational category, the paper attempts to contribute towards a global housing studies that transcends space-time and north-south boundaries.


Starching is a common technique that is used to improve the quality of chicken cube dishes in Chinese cuisine. However, there is little information available for the use of starching chicken cubes as a kind of commercial products. In our study, effect of different levels of the main components for chicken starching, water, starch and salt on the quality of fried chicken cubes was investigated, by determiningcooking yield, moisture content, textural and sensory properties. Results showed that the optimal recipe for chicken cube starching was 6% starch 6% water and 2% salt.


Abstract The neuronal activity has a unique genetic signature that can be used for personal identification and authentication. Continuous authentication of individuals is required in the field involving high security, such as military services, intelligence organizations and secret agencies. Electroencephalogram (EEG) based authentication method is favorable due to its uniqueness and the fact that it can be used even when the person is unconscious. In this study, we investigated the number of samples per subject required to reliably develop a biometric trait authentication system. Initially, we extracted the background EEG signals from the publicly available Temple University Hospital (TUH) database. A total of 46 statistical and frequency domain features were extracted from each EEG signal per subject. The classification was performed using the extreme Gradient Boosting (XGBoost) classifier. We varied the number of EEG signal segments per subject from 5 to 127 with an increment of 5 segments per trial. Finally, the performance parameters such as accuracy, sensitivity, specificity, precision and F-measure were obtained in each case for the biometric authentication system using the test data. Our model achieved the highest accuracy of 100% when more than 75 EEG signals per subject were considered for the analysis. We also identified alpha band power as the most efficient feature for authentication. Our results show that EEG signals can be effectively used for personal identification and authentication.


North American Canis genetics research varies in interpreting the Pre-Columbian distribution of Coyotes ( Canis latrans ). Many studies have relied on generalized species-distribution maps and a few actually cite earlier genetics works as secondary sources. I use archaeological, paleontological, and settlement era documents to demonstrate that Coyotes were present in portions of Minnesota, Wisconsin, and Illinois thousands of years prior to European arrival. This review provides important clarification of historical Coyote distribution in the region and may have implications on the various interpretations of introgressed Coyote haplotypes present in Gray Wolves ( Canis lupus ) throughout the Great Lakes region.


Objectives: Evaluate the prevalence of animal and human bite wounds in patients in a hospital in Recife, State of Pernambuco,Brazil.. Methods: 4.548 people coming from the Surgery ,Traumatology and Bucomaxillofacial Restorative Hospital were studied from April, 1998 to April,2002. The following variables were analyzed: prevalence of bite wound, sex, age, etiologic factor, the origin of the animal and treatment. Results: 24 cases of animal and human bites were observed and they all showed a low incidence (0.52%) for this kind of trauma. It was most frequent in males (78%), teenager (91.69%), patients coming from the capital of the state of Pernambuco, Recife (73%).Concerning etiology ,67% were victims of dog bites, followed by cat bites (26%) and human bites (7%). In 83% of the animal bites, the patients were aware of their origins. The primary treatment was the predominant factor (82%). Conclusion: The bite wounds need better care concerning tetanus and rabies prophylaxis because of their high probability of infection due to the variety of microorganisms in the oral cavity. Indexing terms: human bite; animal bite; facial wound.


The authors examined 219 referrals to a forensic psychology outpatient service between 1989 and 1996. Factors including age of client, whether it was first or subsequent referral, number of agencies previously involved, and type of problem were examined to determine their relationship to the outcomes of nonattendance, early dropout, or completion of assessment/therapy. Type of problem for which the referral was made was found to be significant, with referrals for anger control carrying a poor prognosis for successful completion of therapy. Recommendations for the more effective functioning of the service were made.


: Salt Marshes are extremely important medicinal plant for a variety of reasons. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. The present investigation salt marsh plant ( Salicornia brachiata ) was selected and crude extracts were prepared using three different solvents (Methanol, Hexane and Ethyl Acetate) and screening for their antibacterial activity against ten human bacterial pathogens and three fish pathogens were carried out. The methanol extract of Salicornia brachiata inhibited growth of all the human pathogens except Shigella sp and Salmonella paratyphi and maximum zone of inhibition was observed against Streptococcus pyogenes (25 mm). Maximum zone of inhibition (20 mm) was seen in the hexane extract against fish pathogen Aeromonas sp . The negative control DMSO did not show any antibacterial activity against the tested pathogens. The results of the present study reported that the great effect of Salicornia brachiata methanol extract against some of the most important human and fish pathogens.


With the constant development of economy in our country, the city process also significantly faster, now is becoming more and more good urban design and planning, urban greening and landscape is also more and more common, people has higher requirement to the residential environment in the city now, today's landscape is the important content of ecological planning in the city, and a good set a good natural landscape can not only to the city image, also can bring the city live people a good ecological environment, it can greatly improve the quality of people's happiness and life. At the same time, good landscape can also reduce the harm of automobile exhaust, absorb harmful gases. Nowadays, more and more people pay attention to the ecological environment. Under such circumstances, the ecological concept should be integrated into the landscape design in the construction to achieve the purpose of environmental protection.


In this paper, a study of double diffusive convection in an anisotropic porous layer, saturated with viscoelastic fluid, heated form below, and cooled from above, has been performed; the fluid and solid phases are not in thermal equilibrium. Extended Darcy model, which includes the time derivative term in the momentum equation, has been used. For the fluid and solid phase temperature fields, a two-field model has been used separately for energy equation. Linear stability analysis is performed, using normal mode technique, and the expression for Rayleigh number has been obtained. It is found that small inter-phase heat coefficient has substantial effect on the stability of the system. The criterion for both stationary and oscillatory convection is derived analytically. The effects of various parameters on the stability of the system have been investigated. A weak nonlinear stability analysis based on the truncated representation of Fourier series is performed to find Nusselt number and Sherwood number. Fur...


Extensive optical and radio monitoring data and seven multifrequency spectra were obtained of the violently
variable quasar 3C 446. The monitoring data suggest a correlation between the radio and optical outbursts,
with the optical flare preceding the radio activity by 400-600 days. A difference in the statistical behavior of the optical and radio variability indicates that considerable processing occurs to the optical emitting plasma before it becomes radio emitting plasma. Within the radio band, outbursts proceed from high to low frequencies. An outburst in 1983 showed greater and more rapid variation in the optical than in the near-IR region. The 10-100 μm fluxes did not follow the higher frequency variation, suggesting a time delay between these spectral domains. During another time, the X-ray emission varied on a time scale of days and more rapidly than the UV or optical emission. On a time scale of weeks-months, the X-ray fluxes are well correlated with the UV-IR fluxes but not with the radio fluxes. The multifrequency data show that the flat radio spectrum turns over at 3-10 x 10^(11) Hz and the continuum steepens with frequency; ɑ(IR) = 1.1, ɑ(opt-UV) = -2 to -3. The X-ray emission lies an order of magnitude above an extrapolation of the optical-UV spectrum and has a harder spectrum. The power is primarily
concentrated in the submillimeter and infrared region. When the source is faint, a blue bump may be present. The flux in the Lycx line is proportional to the UV continuum flux density when the source is bright but is independent of the continuum level when the source is faint. The data suggest that the X-rays are produced by the inverse Compton process from an emitting region (10^(16) cm) smaller than but related to the synchrotron emitting UV-IR region. The characteristic size of the emitting region increases with decreasing frequency from 10^(16) (X-ray region) to 1-3 x 10^(17) cm (far IR-submillimeter region) to 10^(19)-10^(20) cm (radio region). Plasma conditions are best constrained at the frequency when the source becomes transparent, the far IR-submillimeter band, where B ≈ 3-100 G, n ≈ 40-100 cm^(-3); and the Doppler boosting factor δ ≈ 1-5.


This paper proposes a new payment system which is based on ANSI X9.59-2006 and adds extra features on top of this standard. The X9.59 is an account based and consumer-oriented payment protocol. It utilizes the existing financial network and financial messages to complete the payment process. However, there are two main limitations in this standard. This paper provides the solution to solve the limitations by adding the merchant authentication feature during payment cycle and to eliminate the requirement of addenda records to be added in the existing financial messages. In addition, the paper provides other functions which are not presented in the X9.59 standard. Three simulation models have been built for the SET, X9.59 and the proposed system in order to analyze their performance and their levels of security.


We have identified 15 extended ultraviolet (XUV) disks in a largely field sample of 38 E/S0 galaxies that have stellar masses primarily below ∼4 × 1010 M☉ and comparable numbers on the red and blue sequences. We use a new purely quantitative XUV-disk definition designed with reference to the "Type 1" XUV-disk definition found in the literature, requiring UV extension relative to a UV-defined star formation threshold radius. The 39% ± 9% XUV-disk frequency for these E/S0s is roughly twice the ∼20% reported for late-type galaxies (although differences in XUV-disk criteria complicate the comparison), possibly indicating that XUV disks are preferentially associated with galaxies experiencing weak or inefficient star formation. Consistent with this interpretation, we find that the XUV disks in our sample do not correlate with enhanced outer-disk star formation as traced by blue optical outer-disk colors. However, UV-Bright (UV-B) disk galaxies with blue UV colors outside their optical 50% light radii do display enhanced optical outer-disk star formation as well as enhanced atomic gas content. UV-B disks occur in our E/S0s with a 42+9−8% frequency and need not coincide with XUV disks; thus their combined frequency is 61% ± 9%. For both XUV and UV-B disks, UV colors typically imply <1 Gyr ages, and most such disks extend beyond the optical R25 radius. XUV disks occur over the full sample mass range and on both the red and blue sequences, suggesting an association with galaxy interactions or another similarly general evolutionary process. In contrast, UV-B disks favor the blue sequence and may also prefer low masses, perhaps reflecting the onset of cold-mode gas accretion or another mass-dependent evolutionary process. Virtually all blue E/S0s in the gas-rich regime below stellar mass Mt ∼ 5 × 109 M☉ (the "gas-richness threshold mass") display UV-B disks, supporting the previously suggested association of this population with active disk growth.


The Indo-Gangetic Plain (IGP) covers approximately 13% of the total geographical area of India and produces nearly 50% of the country's food grains to feed 40% of the total population of the country. The production of grains was, however, not uniform across the IGP regions because of the spatial variation in land-resource characteristics and socioeconomic in the region. Our study includes diversity analysis of entomopathogenic nematodes from Tarai region of IGP (Gorakhpur, Deoria, Kushinagar and Maharajganj Districts), India. The diversity analysis of entomopathogenic nematodes effective against H. armigera from soils of Gorakhpur, Deoria, Kushinagar and Maharajganj regions of Gorakhpur division were carried out. The distribution of entomopathogenic nematodes were positively correlated with soil physiological properties such as soil temperature, soil porosity as well as relative humidity. A total of 36 isolates representing three and two different species of Steinernematid and Heterorhabditid genera were isolated. Based on morphometric data, the nematode species were identified as Steinernema abbasi , S . masoodi ,  S. seemae, Heterorhabditis indica and H. bacteriophora . The distribution frequency of entomopathogenic nematodes was found to be 58.3%, 27.8% and 13.9% from cultivated fields, non-cultivated fields and forests/gardens soils respectively. The diversity index (Shannon, Simpson, Margalef's and Pielou index) was also calculated. The PCA analysis was also carried out by using factor 1 and 2 at 58.60% and 25.92% of the total variances respectively.


Infrared Thermography (IrT) has been shown to be capable of detecting and monitoring service induced damage of repair composite structures. Full-field imaging, along with portability are the primary benefits of the thermographic technique. On-line lock-in thermography has been reported to successfully monitor damage propagation or/and stress concentration in composite coupons, as mechanical stresses in structures induce heat concentration phenomena around flaws. During mechanical fatigue, cyclic loading plays the role of the heating source and this allows for critical and subcritical damage identification and monitoring using thermography. The Electrical Potential Change Technique (EPCT) is a new method for damage identification and monitoring during loading. The measurement of electrical potential changes at specific points of Carbon Fiber Reinforced Polymers (CFRPs) under load are reported to enable the monitoring of strain or/and damage accumulation. Along with the aforementioned techniques Finally, Acoustic Emission (AE) method is well known to provide information about the location and type of damage. Damage accumulation due to cyclic loading imposes differentiation of certain parameters of AE like duration and energy. Within the scope of this study, infrared thermography is employed along with AE and EPCT methods in order to assess the integrity of bonded repair patches on composite substrates and to monitor critical and subcritical damage induced by the mechanical loading. The combined methodologies were effective in identifying damage initiation and propagation of bonded composite repairs.


Early detection of fires that can make quick action and decisions is essential in a fire fighting system. However, in reality the detection system that is commonly used by the community is still limited to an alarm that can only be heard when the owner of the house is present. Therefore, the Internet of Things is an alternative that is able to provide smart systems for these needs. The system created in this study aims to prevent or minimize losses from fires so that they can be detected and addressed early. Thus system consists of two sub-parts, such as tool and mobile applications which are integrated with each other. In this study only focused on designing an Android is also known when the condition is alert, it will send a notification to the user or building owner in the form of an early warning, and when the condition is in danger, it will also send a notification to the user or building owner in the form of an early warning and automatically make a call to the fire fighter.


The present study was conducted to investigate common diseases from cage reared tilapia farms inBakerganj for a duration of 10 months from August 2017 to May 2018. Fingerlings of monosex Nile tilapiawith an average weight of 94.1±5.66 g (mean±SD) were stocked in 10 floating net cages each having anarea of 6.09 m×3.048 m×1.83 m (L×W×H) at the densities of 24 fish/m3. Physical parameters of water(Temperature, DO and pH) were measured at the sampling spot and chemical parameters of water (nitrate,phosphate and ammonia) were analyzed in the laboratory. Both water and diseased fish were collectedmonthly to identify fish diseases. The ranges were: water temperature 20.4oC to 31.3oC, dissolved oxygen5.9 to 6.7 mg/l, pH 7.1 to 8.1, phosphate 0.023 to 0.04 mg/l, ammonia 0 to 0.13 mg/l and nitrate 0 to 10.63mg/l. In the month of September and October, nitrate concentration was high and that might be due todischarging of slaughter wastage substances in water at time of Eid-al-Adha festival. Seven genus ofparasites- Chilodonella sp., Trichodina sp., Gyrodactylus sp., Capillaria sp., Orientocreadium sp.,Eustrongylides sp. and Allocreadium sp. were identified and occurrence of relevant diseases caused by theseparasites were also identified during the study period. Trichodiniasis, Chilodonellosis were main parasiticdiseases. Total count of bacteria was determined and a total of five species of bacteria- V. cholerae, V.parahaemolyticus on TCBS agar, E. aerogenes, S. enteritidis and E. coli on VRB media were identified.Total bacterial load was determined 2.78±0.14x105cfu/ml and 4.26±1.21x106cfu/g in water and tilapiarespectively. Enterococcosiswas the main bacterial disease.


Nogo, a protein inhibiting axonal regeneration, exhibits a characteristic isoform‐specific pattern of expression in skeletal muscle of transgenic mice and patients with amyotrophic lateral sclerosis. Here, the increased levels of Nogo‐A or Nogo‐B in muscle biopsies of 15 amyotrophic lateral sclerosis patients significantly correlated with the severity of clinical disability and with the degree of muscle fiber atrophy. Nogo‐A immunoreactivity was observed selectively in atrophic slow‐twitch type I fibers. These results suggest that Nogo expression in muscle is a marker of amyotrophic lateral sclerosis severity.

The quantitative assessment is the main feature in the university teachers performance appraisal system.There is an orientation error in the performance appraisal system.It leads to weakening the university functions and brings the conflict between the executive power and academic power. Quantitative assessment is both the product of administrative intervention and the result of simply drawing on enterprise management.Therefore,reforming the existing university teachers performance appraisal system is imperative.


From 2004 to 2005,investigations were conducted on birds in Daxiangling Nature Reserve.In combination with the related data,there were 265 species found,belonging to 17 orders and 53 families.82.63% of the avian species were residents and summer visitors.The avian funna were composed of 157 Oriential realm species,39 Palearctic realm species and 23 common species,respectively accounting for 71.69%,17.81% and 10.50% of the total of reproductive birds in this region.Among them,5 species are national first-grade protected birds,24 species are national second-grade protected birds,12 species are Sichuan Provincial protected birds and 11 species are endemic to China.


In recent years, the economic activities of colleges and universities, such as school-enterprise cooperation, industry-education integration, teaching, scientific research, financing, investment and so on are increasing. The new government accounting system and comprehensive budge management is fully implemented in 2019. The financial management of higher education institutions is required to be more refined and stringent to cope with the increasingly complicated tasks. It is important to continuously update and promote the concept of financial management in the new financial environment. The importance of communication in financial management can not be underestimated. Effective communication of financial personnel enables work to be carried out more orderly and efficiently, achieving twice the result with half the effort.


INTRODUCTION: Congenital Cholesteatoma incidence is increasing recently. Most of the times, it is an incidental nding. Sometimes patients can come with complaints of otalgia or hard of hearing. Examination reveals a white mass seen behind an intact tympanic membrane. Any previous history of ear discharge cannot rule out the possibility of Congenital Cholesteatoma. DESIGN: Case Report RESULT: We report a case of Congenital Cholesteatoma in the posterosuperior quadrant. Patient had a previous history of ear discharge but on examination there was an intact tympanic membrane with white mass behind it. CT scan helps in assessing the extent of the disease. Surgical removal is the treatment of choice. It depends on the extent of the disease. CONCLUSION: Due to the variability in the clinical presentation, high index of suspicion is needed to diagnose. Early surgical excision should be done. In extensive diseases, canal wall down mastoidectomy may be needed. As these patients are mostly in pediatric age group, Intact Canal Wall Mastoidectomy. Can avoid mastoid cavity and its problems.

Only few years ago, a giant peccary species was discovered in Amazonian Brazil, the fourth species in the Neotropical artiodactyle family Tayassuidae (VAN ROOSMALEN et al. 2007). Being the largest of the four extant peccary species, it was named Pecari maximus. First molecular data showed that it is the sister species of the collared peccary (Pecari tayacu), while the white-lipped peccary (Tayassu pecari) and the Chacoan peccary (Catagonus wagneri) form the sister clade of the two former. The description of P. maximus was one of the spectacular discoveries of a new large mammal species and took place only three decades after the discovery of another Neotropical pig, viz. Catagonus wagneri. The latter species had originally been described as a fossil taxon, and later it was discovered to survive in the Chaco of Paraguay (WETZEL et al. 1975; WETZEL 1977 a, b, 1981). This (re)discovery was long preceded by information provided by Carl BERKHAN, a German farmer resident in the Bolivian Chaco, who reported to M. EISENTRAUT in 1930 on the existence of a third and even fourth peccary species in the Chaco (see EISENTRAUT 1986; BÖHME & HUTTERER 1999; BÖHME & STIELS 2007). Only six decades later the presence of C. wagneri was proven also in Bolivia, one decade after its initial discovery as a living taxon in Paraguay (EISENTRAUT 1986). In the case of P. maximus from Amazonian Brazil, it took only two years since its discovery before it was also found in a neighbouring country. This sighting was made in 2005 and is reported and discussed below.


【Objective】 Identification of hardness-related genes in wheat new lines or cultivars developed very recently in Huang-Huai Wheat Region of China could illustrate the distribution of hardness-related genes and provide important gene germplasm for improvement of wheat quality.【Method】 A total of 109 wheat cultivars or advanced lines widely grown in Huang-huai wheat region were used to identify the phenotype of grain texture and genotype of puroindoline and puroindoline b-2 genes by the technologies of Single Kernel Characterization System(SKCS),PCR amplification with specific primers,restriction enzyme and DNA sequencing.【Result】 The results showed that hard wheat with percentage of 61.5% was predominant while percentages of the mixed and soft wheats were only 15.6% and 22.9%,respectively,in wheat new lines surveyed.Based on SKCS results,grain hardness index of wheat surveyed ranged widely from 3.2 to 82.6.Three puroindoline alleles of Pinb-D1b,Pinb-D1p and Pina-D1b were detected in hard wheat surveyed.Of them,Pinb-D1b is the most prevalent with percentage of 86.5 %,while Pinb-D1p and Pina-D1b were only 7.5% and 6.0%,respectively.Furthermore,based on identification of puroindoline b-2 gene with gene-specific primers,all surveyed bread wheat genomes D and A contained Pinb-D2v1 and Pinb-A2v4 variants,respectively.However,Pinb-B2v3 variant was only identified in the group B of 86 wheat cultivars or lines surveyed,and Pinb-B2v2 variant was found in the group B of remaining 23 cultivars or lines.The results of analysis of yield characters between Pinb-B2v2 and Pinb-B2v3 variants indicated that the averages of grain number,single grain weight,flag leaf length and flag leaf area of genotypes with Pinb-B2v3 variant were significantly higher than those of genotypes with Pinb-B2v2 variant.【Conclusion】 Hard wheat was predominant in the wheat germplasms surveyed and Pinb-D1b was the most popular in hard wheat lines.In addition,the wheat with Pinb-B2v3 possessed relatively superior yield character to wheat with Pinb-B2v2.


A method for preparing solid FOS (fructooligosaccharide) comprises the steps as follows: an FOS liquid is condensed to 65%-72% and is then added to a crystallizing tank, and the temperature is maintained to be 65-72 DEG C for 1-2 hours; the temperature is reduced to 8-12 DEG C at the rate of 2.5-3.5 DEG C each hour, FOS crystal seeds are added in proportion, and constant stirring is performed, so that a large number of crystals are separated by crystallization; filter-pressing and separation are performed, wet crystals are obtained and dried through cold air by a vibrated fluidized bed, and then a crystalline FOS product with the water content smaller than 3% is obtained. The purity of FOS is improved to a certain degree, and the obtained crystalline FOS product has good mobility, uniform grain size and uniform color and luster without yellow.


The modern physical education teaching model has got more and more attention.The teaching model of competition for training is one of worthy learning model in modern physical education teaching.It is more concerned training the interest in sports and personality development of students.How to improve the features are the key issues of teaching activities in modern university.


Three capillary columns, set up in a routine screening system, were tested in temperature-programmed runs. A narrow-bore fused silica capillary, Carbowax deactivated and with a methylsilicone liquid phase, was found to be unstable at higher temperatures, giving irreproducible results and retention indices that varied considerably from those obtained on packed columns. The two other columns, a wide-bore glass capillary and a narrow-bore fused silica capillary, were polysiloxane-deactivated and had a dimethylpolysiloxane liquid phase. Although both showed good stability, reproducibility, and load capacity, retention indices for various drugs still showed discrepancies as compared to corresponding values on packed columns.


The current outbreak of coronavirus disease 2019 (COVID-19) caused by the novel coronavirus named SARS-CoV-2 represents a major global public health problem threatening many countries and territories. Mathematical modelling is one of the non-pharmaceutical public health measures that has the potential to play a crucial role for mitigating the risk and impact of the pandemic. A group of researchers and epidemiologists have developed a machine learning-powered inherent risk of contagion (IRC) analytical framework that, through the geo-referencing of COVID-19 cases in a particular region, is able to provide support to operational platforms from which response and mitigation activities can be planned and executed. This framework dataset provides a coherent picture to track and predict the COVID-19 epidemic post lockdown by piecing together preliminary data on publicly available health statistic metrics alongside the area of reported cases, drivers, vulnerable population, and number of premises that are suspected to become a transmission area between drivers and vulnerable population. The main aim of this new analytical framework is to measure the IRC and provide georeferenced data to protect the health system, aid contact tracing, and prioritise the vulnerable.


Multi-input push-pull converter with multiple-primary-winding is suitable in low and medium-power applications. However, with the increase of input sources, the number of the primary windings and switches increases as well. Based on Pulsating Voltage Source Cells (PVSCs) combination principle, this paper replaces the input voltage source of the single-input push-pull converter with the series or parallel-connected non-isolated pulsating voltage source cells (PVSCs). Thus a family of single-primary-winding (SPW) voltage-fed multi-input push-pull converters can be proposed. Compared with traditional multi-input converters, they have a form of single-Primary-Winding, and therefore we could greatly reduce the size and cost. Since the configuration of a double-input Buck dc/dc converter is very simple, it is chosen as an example in this paper to analysis this MIC. The operation principle and control strategy are illustrated. Finally, simulation and experimental results are presented to verify the correctness of theoretical analysis

Recent findings A literature review revealed five areas of recent study including advances in biometric technology, formula selection for challenging eyes, accurate astigmatic correction, adjustment of IOL calculations for postrefractive eyes with and without prerefractive surgery data, and use of intraoperative IOL calculations. Summary As cataract surgery continues to be one of the most commonly performed surgeries in the United States, it is important to ensure that the most accurate technology, IOL formula, and surgical planning is utilized.


1. The cladoceran, Moina macrocopa americana was cultured axenically on an artificial diet consisting of a particulate and soluble phase. The effect of changes in the quantitative and qualitative dietary fatty acid composition was investigated.2. Qualitative fatty acid differences were made to simulate the unique proportional differences found among four orders of algae, Cyanophyceae, Chlorophyceae, Cryptophyceae, Bacillarophyceae.3. The quality of dietary fatty acids available to Moina exerts an effect upon productivity and the nutritional value of a particular diet in relation to fatty acid composition can be temperature dependent.4. Increased levels of fatty acids in the diet of Moina reduces productivity.5. The cladoceran, Moina macrocopa americana, may be entirely dependent upon diet for its source of fatty acids.6. A partial explanation for the differential nutritiousness of particular species of algae may be their qualitative and quantitative fatty acid content.


Two stochastic processes are called comparable if the one-dimensional transition kernels of one of them can be estimated (from above and/or below) by the other's. We prove lower and upper bounds for the Hausdorff dimension of the sample paths of comparable processes, if one of the processes is a Levy process, our estimates are given in terms of the corresponding indices


Technology incubators are economic development tools used for promoting the concept of growth through innovation and application of technology, support economic development strategies for small business development. It encourage growth from within local economies, while also providing a mechanism for technology transfer. Incubation is the provision of temporary support to start-up enterprises through the delivery of complex services and special environment with the aim of improving their chances of survival in the early phase of the life span and establishing their later intensive growth. Many Incubation Centres were established to influence and promote entrepreneurship thereby adding to economy of a country. However, the established incubation centres need to be evaluated to measure the effectiveness of the incubation programme in promoting entrepreneurship. In this research, we investigate the added value of Technology Incubation to the growth and development of Entrepreneurship, measuring the role of Technology Incubator thereby, finding out the effectiveness of Technology Incubation Centres in the development of Entrepreneurship in Nigeria. We use questionnaires as a tool for data collection. The result from the respondents of the questionnaires shows that Technology Incubation Centre contribute to the development and growth of entrepreneurs in Nigeria. Most of the entrepreneurs make use of the service of the Technology Incubation Centre. The incubation centres also carried out various program and initiative toward the development of entrepreneurs and also involving them with socio-economic development programs.

Background and purpose: Some agricultural practices are considered to be useful tools in biodiversity conservation. Therefore, carabid beetles were collected on post-agricultural fallow land in Western Poland in order to study the impact of mowing treatment. Materials and Methods: Following a "before-after-control-impact" (BACI) study design over the period of two years (2013 – 2014), standard arrays of pitfall traps were installed on six study sites, of which three were treated by mowing at the beginning of July in the second year of study. The influence of this treatment was analysed statistically with respect to the most frequently collected species, selected ecological traits, as well as the mean individual biomass of the carabid assemblages (MIB). Additionally, Non-metric Multidimensional Scaling (NMDS) was carried out. Results: A total of 1995 individuals belonging to 40 species were collected, with species numbers ranging from 11 to 21 and numbers of individuals ranging from 76 to 278 in the samples. Although some species reacted significantly to the mowing treatment and numbers of individuals of forest species significantly decreased on the treatment sites, in general rather weak effects were observed as a result of the mowing measures. The weak effects of the mowing measures may be explained by the low cutting intensity (only once a year) and differences in environmental conditions between the years of study. Conclusions: The results of the study are assumed to be useful in the context of planning mowing measures in order to conserve biological diversity. Yet, the results also underline the importance of long-term studies.


Response of granular insecticides viz. phorate, cartap hydrochloride and carbofuran at recommended and double dosage was tested against earthworm Eisenia fetida. The response was assessed for cocoon production, hatching, increase in biomass and survival of young as well as adult earthworms. Over a period of 60 days, mean number of cocoons produced ranged between 0–3.25, number of juveniles from 2.5–26.8 g and increase in biomass between 0.29–0.86 g. The results revealed that all the tested insecticides were toxic to juveniles while phorate at both the dosages was toxic to cocoons production. However, these insecticides did not affect increase in biomass and survival of adult earthworms.


ABTRACT Investigation of the strength characteristic of soil from alluvial deposit of River Benue in makurdi stabilized with coconut fiber as a stabilizer was carried as local building material for farm structure. Processed coconut fibers were mixed with the soil at four different mix ratios of 1% fiber, 2% fiber, 3% fiber and 4% fiber by percentage weight with 0% fiber as control. Compaction test and compressive strength were carried out on the various stabilizing ratio. From the compaction test, the correlation between the maximum dry density and optimum moisture content is a second order polynomial with a coefficient of 63% obtained at 1.91kg/m 3 and 20.0% respectively while the compressive strength test shows an optimum failure load of 8.62N/mm 2 at 2%fibre:100% soil mix ratio at 2.16 maximum dry density.

To cultivate creative thinking and ability of sports talents,we should change our views of physical education,reform our teaching model,methods and the management system to form a system of originality.


Genetic engineering offers promise in the development of new plant forms. Alterations in plant size, branching, flower color and form, disease resistance, and many other factors may occur in plants produced by new technologies without sexual breeding and selection. Many desirable characteristics, not always observed in plants developed by breeding, are often expressed in plants engineered by tissue culture technology. Some of the plants showing these different new trait(s) also can be reproduced uniformly from seed, thus indicating genetic transmission of the new trait(s). This exciting approach to plant modification has been used to develop new forms of lisianthus.


Detecting dynamic vehicles is of great significance in the field of autonomous vehicles. In the literature, a few vehicle detection methods are proposed to detect vehicles within 50 m from the Lidar, where the point clouds are relatively dense. It is a great challenge to detect vehicles that are far from the Lidar because of sparse point clouds. Fewer returned point clouds will result in a larger fitting randomness and lower detection rate. To tackle this issue, a dynamic vehicle detection method based on likelihood-field-based model combined with coherent point drift (CPD), which includes the steps of dynamic object detection and dynamic vehicle confirmation, is proposed in this paper. An adaptive threshold based on the distance and grid angular resolution is applied to detect the dynamic objects. The pose estimation based on CPD (PE-CPD) is proposed to estimate the vehicle pose. The scaling series algorithm coupled with a Bayesian filter that is improved by PE-CPD is utilized for updating the vehicle states. Finally, comparative experiments of vehicle detection based on KITTI data sets are conducted. The results show that the proposed method improves the detection rate, especially the detection in the radius of 40–80 m, which is termed as distant area, compared with the method based on pose estimation with modified scaling series.

The major advantages of conducting internal investigations only come to light when the results can be disclosed to third parties. At the interface of data protection and criminal procedure law, the work explores how the group-internal transfer of the outcome and the cooperative disclosure to German and US authorities can be justified. The emphasis is placed on the suspect employee. Due to less strict investigation regulations under private law, the information transfer to authorities carries a potential risk of undermining his position as a suspect according to criminal procedure law. The contribution discusses if the new data protection law can adjust the structural imbalances and if it leads to a fairer approach to conducting internal investigations. Besides the highly relevant impact of disclosure orders from US authorities and Art. 48 DS-GVO as a "blocking statute", the work also analyses the exclusion of gained evidence under criminal procedure law.


In modern VLSI design flow, sub-resolution assist feature (SRAF) insertion is one of the resolution enhancement techniques (RETs) to improve chip manufacturing yield. With aggressive feature size continuously scaling down, layout feature learning becomes extremely critical. In this paper, for the first time, we enhance conventional manual feature construction, by proposing a supervised online dictionary learning algorithm for simultaneous feature extraction and dimensionality reduction. By taking advantage of label information, the proposed dictionary learning engine can discriminatively and accurately represent the input data. We further consider SRAF design rules in a global view, and design an integer linear programming model in the post-processing stage of SRAF insertion framework. Experimental results demonstrate that, compared with a state-of-the-art SRAF insertion tool, our framework not only boosts the mask optimization quality in terms of edge placement error (EPE) and process variation (PV) band area, but also achieves some speed-up.


This study investigated the effects on participants' ego state responses and their perception of each other's ego states of a 5-day therapy group using transactional analysis as its theoretical foundation. Twenty-eight third-year psychology students of the University of San Carlos, Cebu City, Philippines, participated in the study. In a pretest-posttest-control group design, 15 participants were assigned to the experimental group that underwent a group therapy patterned after the Gouldings' (1977) redecision therapy, while the remaining 13 students were assigned to the control group. Two posttests were conducted, one immediately following the therapy session and the other 6 weeks after it. Ego states were measured by the Adjective Checklist (ACL) developed by Gough and Heilbrun (1983). Ego state perception was measured by Dusay's (1977) egogram. A Multivariate Analysis of Variance (MANOVA) indicated significant changes in the ego states after the first posttest: Hotelling's T = .69584, F (5, 22) = 3.06171, p < .03, and a near significance, Hotelling's T = .57286, F (5, 22) = 2.52059, p < .059 in the follow-up posttest. Ego states were also perceived to have changed significantly after 6 weeks. The observed pattern seemed to be increasing Nurturing Parent, Adult, and Natural Child ego states and decreasing Critical Parent and Adapted Child ego states. These ego state changes also seemed to be validated by a repeated measures MANOVA, which yielded significant effects on the experimental participants' perception of each others' ego states as measured by the egogram: Hotelling's T = 2.809, F (5, 10) = 5.619, p < .01. Results are discussed in the context of the pattern of ego state changes. Also considered is the limitation of the nomothetic approach in this particular study.

The problems of sports talent dropping out now seriously become a worry of our athletics reform and also become a bottleneck in the growth of athletics development gradually. This thesis will analyze present condition, reason, result of sports talent loss under the background of 2008 Olympics, and put forward the countermeasures.


Large explosive volcanic eruptions inject sulphur into the stratosphere where it is converted to sulphur dioxide and sulphate aerosols. Due to atmospheric circulation patterns, aerosols from high-latitude eruptions typically remain concentrated in the hemisphere in which they are injected. Eruptions in the high-latitude Northern Hemisphere could thus lead to a stronger hemispheric radiative forcing and surface climate response than tropical eruptions, a claim that is supported by a previous study based on proxy records and the coupled aerosol-general circulation model MAECHAM5-HAM. Additionally, the subsequent surface deposition of volcanic sulphate is potentially harmful to humans and ecosystems, and an improved understanding of the deposition over polar ice sheets can contribute to better reconstructions of historical volcanic forcing. On this basis, we model Icelandic explosive eruptions in a pre-industrial atmosphere, taking both volcanic sulphur and halogen loading into account. We use the fully coupled Earth system model CESM2 with the atmospheric component WACCM6, which extends to the lower thermosphere and has prognostic stratospheric aerosols and full chemistry. In order to study the volcanic impacts on the atmosphere, environment, and sulphate deposition, we vary eruption parameters such as sulphur and halogen loading, and injection altitude and season. The modelled volcanic sulphate deposition is compared to the deposition in ice cores following comparable historical eruptions. Furthermore, we evaluate the potential environmental impacts of sulphate deposition. To study inter-model differences, we also compare the CESM2-WACCM6 simulations to similar Icelandic eruption experiments simulated with MAECHAM5-HAM.


Broken wire was a vital disadvantage for quality assurance of locked coil wire rope. A nondestructive system for monitoring broken wires in production line was designed, which based on the magnetic character of locked coil wire rope. The system that applied leakage flux theory consisted of testing sensor, signal acquisition unit, computer system and unit for alerting and marking. Intelligent signal processing was applied in the system for effective discrimination of broken wire and subsequent processing. The reliability of the system was proved by the results from laboratory and factory.


Rose-Hulman Ventures (RHV) began in 1999 at the Rose-Hulman Institute of Technology as a unique program providing outstanding experiential learning opportunities for math, science, and engineering students. Funded by the Lilly Endowment Inc., the program has been an incubator/ technology center engaging students and technology-based companies in project work that provides students employment with the challenges and excitement of real professional practice. Over 1500 internship positions have been offered to 575 students working on a range of design, prototyping, and testing projects for over 84 client companies. The challenges of educating the 21 st century engineer call for innovative approaches in both curricular and co-curricular programs. The global economy and highly competitive workplace of today are creating needs for a solid technical education combined with professional practice experiences in the undergraduate curriculum. Many programs focusing on industrial partnerships, service learning, or other project based experiences have been documented. These are usually offered as a for-credit course, often as part of the senior design experience. Rose-Hulman Ventures takes a unique, co-curricular approach. For the student, the program offers paid internships on-campus and is like working at a real job. It offers unique benefits beyond a curriculum based approach to both the client companies and students, including realistic, cross functional views of the innovation process and the very real need for useful deliverables that in many cases have been important inputs to business success or failure. A key feature of the program is the role of project managers who are full time professional staff members that serve in a project management and leadership role for the student teams and assure professional level results. This paper describes Rose-Hulman Ventures, the mechanics of the project work, and the synergistic benefits for students, the industrial clients, and the Institute as a whole. Particular emphasis is placed on benefits of a co-curricular approach to professional practice experiences and learning outcomes and to client companies. These include the ability to easily assemble

Objective To investigate the ultrasonic diagnosis of abdominal ultrasonogram in patients with acute graft versus host disease(aGVHD) who receive allogenic hemopoietic stem cell transplantation(Allo-HSCT). Methods We regularly practiced abdominal ultrasound examination weekly in 73 Allo-HSCT patients, and contrasted the ultrasonographic characteristics in 43 aGVHD patients with those in 30 patients who did not present aGVHD. Results As compared with those of the control group, the abdominal ultrasonic images of the aGVHD patients obviously changed (P0.05), including increased spleen volume, gallbladder wall thickening, cholestasis, liver diffuse parenchyma lesions,and abnormal enterokinesia. Conclusion The conventional abdominal ultrasound examination in Allo-HSCT patients provides reliable diagnosis evidence of aGVHD.


function properties is postulated. Furthermore, an expert-free interface design methodology able to meet these properties, and based on the concept of optimal interfaces, is proposed. This concept simply states an equivalence between information formats (numeric and linguistic), thereby making the methodology appealing from the applicational point of view. An algorithm is developed, and brief notes on selected applications are outlined stressing relevant issues of the proposed methodology.


Group testing has been successful in minimizing the cost of testing a large batch of samples by pooling them together. In this work, we study the setting where samples arrive over time. Since not all samples are available at the same time, we incur a waiting cost in letting many samples accumulate. However, testing too soon leads to a large testing cost by missing the benefits of pooling a larger number of samples. We consider the problem of minimizing the combined objective of average wait time plus testing cost, and develop online algorithms that are provably competitive for a broad range of testing-cost functions. We also give a lower bound on the competitive ratio that no online algorithm can beat.


The Bachelor thesis deals with the phenomenon of blogs and its integration in the field of marketing communications. It maps out theoretical- historical aspects of blogs and defines basic notions such as blogger, fashion blogger, blog ethics or blog publicity. Theoretical knowledge is then transferred to real experience with the help of own blog analysis and individual interviews with the selected fashion bloggers with the target to find common characters of these blogs or determine ways how the fashion bloggers can present and promote themselves. Important part of the practical segment of this thesis is a readers' opinion which is determined through qualitative research method of focus group. These observations are summarized in the conclusion of the thesis together with a brief recommendation of fashion blogs for the future.


This document is based on the revision of personal diaries of interviewers who are part of a research team in the South of Florida, United States. The original study explored the patterns of care provided to elderly people at home. The reflecting personal diaries stimulated a broaden discussion on the researched topic, presented the human aspect of quantitative data and, given the sensible character of the topic under study, served the researchers to identify and explore their own emotions prior to meeting the participants of the study. Our experience confirms the need to use qualitative mythological instruments that help reveal the phenomenon under research "just as it occurs", through complementing the quantitative evidence. The argument is that having an open and self-reflective attitude, in the middle of the current enthusiasm for practice based on evidence, is not only applicable in the framework of nursing research but within the same professional practice.


Language teaching represents one of the language sciences that can be regarded as applicative (Balboni). The teaching of modern languages is a discipline that is intrinsically interconnected with other disciplines and, from the moment it was scientifically recognized on the epistemological level, it has been characterized by a keen interest and affinity towards the technologies (Favata 56). This essay showcases the results of a survey conducted on a sample of teachers on the effects of the pandemic on language teaching in Italy


The increasing awareness towards sustainable development of electronics has driven the search for natural bio-organic materials in place of conventional electronic materials. The concept of using natural bio-organic materials in electronics provides not only an effective solution to address global electronic waste crisis, but also a compelling template for sustainable electronics manufacturing. This paper attempts to provide an overview of using Aloe vera gel as a natural bio-organic material for various electronic applications. Important concepts such as responses of living Aloe vera plant towards electrical stimuli and demonstrations of Aloe vera films as passive and active regions of electronic devices are highlighted in chronological order. The biodegradability and biocompatibility of Aloe vera can bring the world a step closer towards the ultimate goal of sustainable development of electronic devices from "all-natural" materials.The increasing awareness towards sustainable development of electronics has driven the search for natural bio-organic materials in place of conventional electronic materials.

The purpose of this study was to examine the acoustic and electroglottographic features in the characterization of passaggio in female singers. Three groups of female singers were instructed to sing the notes of the scale for one octave using an "ah" vowel. When singing this octave they sang through a register shift, which is called "passaggio." Their singing voices were recorded in a two-channel dataset. The first channel captured the acoustic signal using a microphone, and the second channel captured the electroglottographic (EGG) signal using an EGG instrument. A customized MatLab algorithm was designed to analyze the features of the two-channel dataset that contribute to the characterization of the passaggio in female singers. Glottal measurements can give robust information on precise glottal closing moments using the derivative of the EGG signal (dEGG) and speech acoustic waveform measurements can give similar information on glottal opening moments using the derivative of the audio signal (dAUDIO). ...


This paper focuses on the correlation between negative health shocks and the households' shareof wealth held in risky assets. By using U.S. data from the Health and Retirement Study, we try toestablish a link between negative health shocks and financial outcomes such as a household's probabilityof owning risky assets and share of risky assets held. In our definition of a recent negative health shock,we include: cancer or malignant tumor diagnoses, stroke or transient ischemic attack, and heart attack,coronary heart disease, angina, congestive heart failure, or other heart problems. We find an importantnegative correlation between a negative health shock to the female and her household's probabilityof owning risky assets and share of risky assets held, respectively. In contrast, we do not find acorresponding statistically significant correlation for males.
