A Robust Data Gathering Technique for Large Scaled Wireless Sensor Networks

In this paper we propose a data gathering scheme for large scaled wireless sensor networks using multiple mobile data collectors (MDCs) and the spatial division multiple access (SDMA) technique. We focus on minimizing the data gathering time by employing the SDMA technique, and minimizing the length of touring paths of MDCs by employing Voronoi diagrams. The proposed scheme facilitates all deployed sensors to experience uniform energy depletion by avoiding long-distance transmissions to the base station. This, in turns, helps to prolong the lifetime of the network, and the network remains connected for longer period of time and increases the robustness. Simulation results demonstrate that the proposed scheme greatly reduces the traversal distance of the data collectors compared to the grid based approximation algorithm, prolongs the network lifetime significantly compared to a network which has only a static data collector, or a network in which the mobile collectors only move along straight lines.
Oxygen Metabolism During Liver Transplantation: The Effect of Dichloroacetate

Dichloroacetate (DCA) stimulates pyruvate dehydrogenase (PDH), accelerating recovery of the postischemic heart.Because DCA also stimulates hepatic PDH, it may facilitate graft recovery during liver transplantation (OLT). Hepatic removal and replacement during OLT produce major changes in O2 consumption (VO2), and return of baseline VO2 has been used to index early graft function. We examined the effect of DCA on O2 metabolism during OLT. Forty patients received DCA 80 mg/kg intravenously in divided doses, and 40 served as controls. Serial measurements were made for body temperature, hemodynamics, O2 metabolic indices, and plasma substrate and hormonal concentrations. Oxygen delivery (DO2 I) and consumption (VO2 I) indices were calculated. Patients exhibited stable hemodynamics, with similar fluid and blood product requirements. Compared with the dissection stage, DO2 I and VO2 I were decreased during the anhepatic stage (31% and 36%, respectively), then returned to dissection stage values soon after portal vein unclamping. Temperature decreased during the anhepatic stage and returned toward dissection stage value after graft perfusion. DCA reduced lactic acidosis and NaHCO3 use but did not alter hemodynamics or measures of O2 metabolism or body temperature. VO2 is decreased during the anhepatic stage largely due to loss of hepatic metabolism. Restoration of VO2 by 30 min after portal vein unclamping reflects rapid recovery of O2 metabolism by the graft liver, but DCA does not accelerate recovery of VO2. DCA does not seem to facilitate early graft hepatic function as indexed by VO2. Implications: We evaluated whether dichloroacetate, which stimulates pyruvate dehydrogenase, can accelerate recovery of graft liver hepatic function during liver transplantation, as indexed by oxygen consumption. We found that despite evidence that it activated pyruvate dehydrogenase, dichloroacetate did not affect recovery of transplanted liver function. (Anesth Analg 1997;85:746-52)
Percutaneous Application of Panax notoginseng Extract Improves the Strength of a Healing Ligament

This study compared the effects of Panax notoginseng (PN) extract with a composite herbal application on the healing of medial collateral ligaments (MCL) in rats. Twenty-nine rats receiving surgical tensile rupture to their right MCLs were tested. Ten rats were treated with an alcohol pad application (Group 1), 9 were treated with a composite herbal application (Group 2) and 10 were treated with an alcohol extract of PN to their right knees (Group 3). The treatments were applied percutaneously over the medial side of their right knee with adhesive plaster stabilization. The plaster and medication in all groups was changed every other day throughout the study to maintain moisture of the medication. The MCLs were harvested and tested for the biomechanical properties at 2 weeks after injury. Results revealed that the normalized ultimate tensile strength and structural stiffness of Group 3 were higher than those of Groups 1 and 2 (p=0.029 and 0.062 respectively), whereas Groups 1 and 2 were not different from one another. We conclude that PN extract application improves the mechanical strength of repairing MCLs at 2 weeks after injury. _____________________________________________________________________________________________________________
Diagnosis of lymphadenopathies by FNAC: a prospective study

Objective: To determine the incidence of various pathological lesions involving lymph nodes by using simple and easy diagnostic tool (FNAC) and prove the diagnostic importance of FNAC. Materials and methods: Our study included 1926 cases of lymphadenopathy, between January 2012 and December 2013. Patients with palpable lymph nodes anywhere in the body with a valid requisition were included in the study. All the demographic details, history and clinical findings of the swelling are taken by the attending pathologist. Results: Our study included 1926 cases of lymphadenopathy , we reported 1136 cases (59 %) as granulomatous lymphadenitis , 500 cases ( 26 %) of Non-specific lymphadenitis , 232 cases (12%) of Lympho-proliferative disorders (Hodgkin’s and NonHodgkin’s disease) 58 cases (03%) metastases from primary site. Our study also showed the incidence of lympho-proliferative diseases in association with Human Immuno-deficiency Virus (HIV) infection (144 cases). Majority of the granulomatous lymphadenitis cases were associated with HIV cases constituting about 66.5 % (756 cases). Conclusion: Fine Needle Aspiration Cytology is a simple, safe, rapid, cost effective and reasonably accurate method of establishing the diagnosis of lymphadenopathy. Overall accuracy of FNAC in comparison with the histopathological study is very high and may obviate the need of excision biopsy when the findings are compatible with the clinical diagnosis. The high accuracy rate of aspiration cytology of lymph nodes calls for its wide application in daily practice.

An Exploratory Analysis of Risks in Green Residential Building Construction Projects: The Case of Singapore

Recently, an increasing number of green residential buildings have been developed worldwide owing to active promotion from the authorities and increasing interest from customers. However, in the same way as traditional residential buildings, the construction of green residential buildings faces various risks. The aims of this study are to identify and assess the diverse risks in green residential building construction projects, compare their risk criticalities with those in traditional counterparts, and propose helpful risk mitigation measures. To achieve these goals, a comprehensive literature review was first conducted, and a questionnaire was then administered to 30 construction companies in Singapore. Survey results showed that “complex procedures to obtain approvals”, “overlooked high initial cost”, “unclear requirements of owners”, “employment constraint”, and “lack of availability of green materials and equipment” were the top five critical risks in green residential building construction projects. Survey results also showed that green residential building projects were facing risks at a more critical level than those traditional residential building projects. Additionally, this study proposed fourteen risk mitigation measures to tackle the risks in green residential building construction projects. This study has contributed to the body of knowledge by identifying and evaluating the critical risks and mitigation measures in green residential building construction projects. Meanwhile, the findings from this study can also provide an in-depth understanding of risk management in green residential building construction projects to practitioners and thus benefit the practice.
'Best practice' development and transfer in the NHS: the importance of process as well as product knowledge

A core prescription from the knowledge management movement is that the successful management of organizational knowledge will prevent firms from 'reinventing the wheel', in particular through the transfer of 'best practices'. Our findings challenge this logic. They suggest instead that knowledge is emergent and enacted in practice, and that normally those involved in a given practice have only a partial understanding of the overall practice. Generating knowledge about current practice is therefore a precursor to changing that practice. In this sense, knowledge transfer does not occur independently of or in sequence to knowledge generation, but instead the process of knowledge generation and its transfer are inexorably intertwined. Thus, rather than transferring 'product' knowledge about the new 'best practice' per se, our analysis suggests that it is more useful to transfer 'process' knowledge about effective ways to generate the knowledge of existing practice, which is the essential starting point for attempts to change that practice.
Galantamine treatment of cognitive impairment in bipolar disorder: four cases.

OBJECTIVE To determine if galantamine is effective in the treatment of chronic cognitive impairment in bipolar disorder. METHODS All charts of patients meeting DSM-IV criteria for bipolar disorder treated with galantamine in an academic bipolar disorder specialty clinic psychiatric practice were reviewed and clinical response was assessed retrospectively using the Clinical Global Impression scale for Improvement. RESULTS Galantamine was effective in two of four patients, both of whom took at least 24 mg/day. It was ineffective in two patients who only took 8 mg/day. Sedation limited higher dosing in one patient, and a second patient experienced sedation and tremor. Improvement in cognition was not associated with improvement in mood. Galantamine appeared neutral in its effect on mood. CONCLUSIONS This pilot case series suggests that galantamine may have some utility in improving chronic cognitive impairment in bipolar disorder. Larger studies are required to clarify these initial pilot data.
Mathematics Teachers’ Views of Accountability Testing Revealed through Lesson Study

The practice of lesson study, a professional development model originating in Japan, aligns well with recommendations from research for teacher professional development. Lesson study is also an inductive research method that uncovers student thinking and, in parallel, grants teacher-educators the opportunity to study teachers’ thinking about related issues. One issue for teachers in North America is the focus on student achievement measured through accountability testing. The purpose of this article is to describe how lesson study elicits teachers’ views, knowledge, and practices. To illustrate how teachers’ thinking emerges during lesson study activities, the paper will outline four different views of accountability testing revealed by grades 6-10 mathematics teachers from nine different independent school districts in West Texas during various phases of lesson study. In addition, how each view influenced the teaching of students, as noted by teachers during postlesson discussions from three different lesson studies during 2006 – 2009 is reported. Descriptions of interactions among these teachers and higher education faculty housed in mathematics and teacher education departments at a local university and teachers’ self-reported reflections along with changes in practice are included.
Impact of Interest Rate Changes on the Profitability of four Major Commercial Banks in Pakistan

The core objective of this project is to analyze the impact of interest rates changes on the profitability of commercial banks being operated in Pakistan by examining the financial statements of four major banks during 2008 to 2012. Like the efficiency of banking sector is considered most important for economic growth, monetary policy implementation and macro-economic stability. From the past few years, interest spread of banking sector of Pakistan is rising. As a result variations in the interest rate depress the savings and investment and on the other hand it increases the efficiency of banks’ lending. In this paper interest rate is an independent variable and bank profitability is a dependent variable. To examine the impact of interest rate changes on the profitability of commercial banks in Pakistan, Pearson correlation method is used in this study. As a result it is found that there is strong and positive correlation between interest rate and commercial banks’ profitability. It means if the value of interest rate is increases/decreases then as result value of banks’ profitability will also increases/decreases.
Comparison of phencyclidine hydrochloride (Sernyl) with other drugs. Simulation of schizophrenic performance with phencyclidine hydrochloride (Sernyl), lysergic acid diethylamide (LSD-25), and amobarbital (Amytal) sodium; II. Symbolic and sequential thinking.

In a previous report 7 the administration of phencyclidine hydrochloride, a chemical compound with anesthetic and sedative properties, was shown to produce profound disturbances in reaction time, motor learning, and weight discrimination. These findings were obtained with normal subjects who had been given subanesthetic doses of the drug. The degree and pattern of drug-produced deficits closely approximated those found in a group of chronic schizophrenic patients given the same battery of tests without drugs. These psychotomimetic effects could not be attributed solely to the drug's hallucinogenic or to its sedative properties, since other drugs with each of these properties (lysergic acid diethylamide [LSD-25] and amobarbital sodium) produced neither the degree nor the pattern of deficits demonstrated under phencyclidine hydrochloride. It was tentatively concluded that the deficits seen in normal subjects under phencyclidine hydrochloride and in chronic schizophrenia might be attributable to a common underlying
Is the Loss of pRb Essential for the Mouse Skin

The pRb pathway is inactivated in most, if not all, human and mouse tumors, including skin tumors.However, a relatively low frequency of Rb gene alterations is found. The embryonic lethality of pRbdeficientanimals restricts the analysis of these mice to midgestation and precludes the analysis of the rolesof pRb in mouse cancer models. To solve this problem, we used the Cre/LoxP technology to induce thetissue-specific deletion of pRb. In epidermis, pRb deletion leads to altered proliferation and differentiationbut these alterations do not induce the development of spontaneous skin tumors. To gain insight in thepossible roles of pRb in mouse skin carcinogenesis, we have performed chemical tumorigenesisexperiments in mice bearing epidermal-specific inactivation of Rb gene. Unexpectedly, these mice developfewer and smaller tumors than control animals, but showing increased malignant conversion to squamouscell carcinomas. Detailed biochemical analysis demonstrates that, in the absence of pRb, multiple pathwaysare activated leading to increased tumor apoptosis. In particular, we characterized the aberrant p53activation mediated by E2F/p19ARF and other transduction pathways. This may generate a selective pressurein the tumor leading to premature p53 loss of function, which ultimately results in increased malignancy.Overall, these data highlights the role of pRb during the malignant conversion in the mouse skincarcinogenesis, and the intimate relationships between pRb and multiple tumor suppressor networks in thissystem.
Patterns of mineral occurrence in metamorphic rocks

Abstract Patterns in the occurrence of minerals in metamorphic rocks suggest additional opportunities for investigating chemical and physical processes during metamorphism. Three such patterns are reviewed. First, trace minerals in metamorphic rocks commonly occur with regular distributions indicating their participation in prograde reactions that can be mapped as isograds. Examples include the distribution of allanite and monazite in pelitic rocks and of zircon and baddeleyite in siliceous dolomites. Recognition of these isograds points to the potential for developing a chronology of specific chemical reactions during metamorphism and for defining the P-T conditions of those reactions. Second, the mineralogical products of retrograde metamorphism in many cases occur in distinctive associations that are consistent with partial mineral-fluid equilibrium. Examples include the distribution of retrograde calcite, quartz, and tremolite in siliceous limestones and of retrograde tremolite, dolomite, brucite, and serpentine in siliceous dolomites from contact aureoles. Among other things, application of partial equilibrium to retrograde metamorphic rocks leads to constraints on the amount and direction of fluid flow in contact aureoles as they cool. Third, pseudomorphs are typically absent from prograde metamorphic rocks but are common in retrograde metamorphic rocks. The distribution may be explained by the effect of “force of crystallization. ” The pattern of occurrence of pseudomorphs thus suggests novel phenomena during metamorphism that develop from an interplay between chemical and mechanical processes
Brief psychological interventions ("debriefing") for trauma-related symptoms and the prevention of post traumatic stress disorder.

OBJECTIVES To assess the effectiveness of brief psychological debriefing for the management of psychological distress after trauma, and the prevention of post traumatic stress disorder. SEARCH STRATEGY Electronic searching of MEDLINE, EMBASE, PsychLit, PILOTS, Biosis, Pascal, Occ.Safety and Health, CDSR and the Trials Register of the Depression, Anxiety and Neurosis group. Hand search of Journal of Traumatic Stress. Contact with leading researchers. SELECTION CRITERIA The inclusion criteria for all randomized studies was that they should focus on persons recently (one month or less) exposed to a traumatic event, should consist of a single session only, and that the intervention involve some form of emotional processing/ventilation by encouraging recollection/reworking of the traumatic event accompanied by normalisation of emotional reaction to the event. DATA COLLECTION AND ANALYSIS 8 trials fulfilled the inclusion criteria. Quality was generally poor. Data from two trials could not be synthesised. MAIN RESULTS Single session individual debriefing did not reduce psychological distress nor prevent the onset of post traumatic stress disorder (PTSD). Those who received the intervention showed no significant short term (3-5 months) in the risk of PTSD (pooled odds ratio 1.0, 95% ci 0.6-1.8). At one year one trial reported that there was a significantly increased risk of PTSD in those receiving debriefing (odds ratio 2.9, 95% ci 1.1-7.5). The pooled odds ratio for the two trials with follow ups just included unity (odds ratio 2.0, 95% ci 0.9-4.5). There was also no evidence that debriefing reduced general psychological morbidity, depression or anxiety. REVIEWER'S CONCLUSIONS There is no current evidence that psychological debriefing is a useful treatment for the prevention of post traumatic stress disorder after traumatic incidents. Compulsory debriefing of victims of trauma should cease.
Factors Influencing the Use of DP Chargeback Information

A field survey was conducted to study the factors associated with the use of data processing chargeback information in organizations. The aim of this research was to identify the organizational and budgetary characteristics associated with how the output of a chargeback system is used by user-managers to control their data processing costs. It was found that involvement in budget preparation, accountability for meeting the data processing budget, and cost variability of the charges were the most important factors to consider when designing data processing chargeback systems.
Diagnostic accuracy of two-step postexercise ECG. Results of 305 subjects studied by coronary arteriography.

A total of 305 selected patients with chest pain syndromes were studied with both the two-step test and selective coronary cinearteriography. All patients were suspected clinically of having coronary artery disease. Subjects with positive responses were subdivided according to degree of ischemic R-ST depression, and those with negative responses according to immediate postexercise heart rate. Results of this study suggest that the diagnostic accuracy of a moderate stress test (such as the two-step) is greatly enhanced when postexercise heart rate, degree of R-ST depression, and presence of preexercise electrocardiographic abnormalities are considered. Retention of the two-step test as a screening procedure appears justified.
Oral health and malocclusion in 10-to-11 years-old children in southern Italy.

AIM This study had two main goals: the evaluation of caries experience in permanent teeth and the analysis of malocclusion prevalence. STUDY DESIGN Observational cross-sectional survey. METHODS The sample consisted of all the 5th graders of 'Gio Leonardo di Bona', the only Public School in Cutro, a small urban area in Southern Italy (10,000 inhabitants). The clinical examination was performed by a trained dentist at the school infirmary, and no radiographs, study casts, or previous written records of the children were available. DMFS-DMFT and Index of Orthodontic Treatment Need (IOTN) were used to fulfil the study objectives. After the examination, parents received a report on presence/absence of dental caries and possible orthodontic treatment need. Statistics All data were analysed with StatView and Stata 8.0 software. The Chi-square test was applied to compare prevalence rates. The Chi-square linearity was used to evaluate whether caries and malocclusion prevalence changed with a steady trend with reference to sex. RESULTS The 94% (n. 97) of the whole sample gave a positive consent to the screening. The overall mean of DFS was 4.30 (4.74 SD) while the mean of DFT was 2.60 (2.03 SD). The 22.7% of the sample had DFS/T = 0. Statistically significant difference between genders according to DFS (p = 0.017) and DFT (p = 0.002) distribution was found, being females' significantly lower than males'. Using the DHC-IOTN, 51.6% of the children were assigned to the no/little need, 26.8% to borderline need and 21.6% to a great need for orthodontic treatment. There was no statistically significant difference by gender according to distribution of occlusal traits (p> 0.05), except in the anterior cross bite, being males significantly more affected (p = 0.030). CONCLUSIONS We believe that oral health and orthodontic surveys performed on a higher number of patients at an early age are critical in order to enhance early treatment, thus avoiding severe malocclusions and progression of dental caries. The results of our study indicate that 21.6% of the sample had an objective orthodontic treatment need (grades 4-5 DHC-IOTN). The single Aesthetic Component (AC) score of the IOTN failed to identify orthodontic treatment needs in our sample: only 13% rated themselves as being in categories 5-10 (great aesthetic need for treatment). With reference to dental caries, males had a mean DFT (3.20) higher than the WHO's 2000 Oral Health Goal for 12-years-olds (DFT = 3) while females (DFT = 1.96) were significantly under this target. The children were advised to undergo regular examinations and to change their lifestyle habits.
