Right atrial myxoma-induced syncope

A 42-year-old woman presented with a 3-month history of transient episodes of syncope. These sudden episodes occurred without warning and were associated with loss of consciousness, palpitations, epigastric discomfort and a fixed upward gaze of both eyes. Her symptoms had progressed with increasing frequency to 2–3 times a day and each episode persisted for more than 20 min. The patient had no significant medical or family history. Her physical examination was unremarkable and no arrhythmias were noted on ECG. Blood tests and head CT images were unremarkable. A bedside transthoracic echocardiogram was performed, which showed in subcostal view, an elliptical shaped mobile mass located in the right atrium, measuring about 6 cm×5 cm in size, prolapsing through the tricuspid valve into the right ventricle during diastole (figure 1A,B). The right atrium, right ventricle and inferior vena cava were enlarged. Figure 1 Echocardiogram showing …
Fathers ' Multiple-Partner Fertility and Children ’ s Educational Outcomes

We find substantial and statistically significant detrimental effects of fathers' multiple-partner fertility (MPF) on children's educational outcomes. We focus on children in fathers’ “second families” when the second families are nuclear families – households consisting of a man, a woman, their joint children, and no other children. We analyze outcomes for almost 75,000 Norwegian children, all of whom, until they were at least age 18, lived in nuclear families. Controlling for a rich set of socio-economic variables, we find that children who spent their entire childhoods in nuclear families but whose fathers had children from a previous relationship living elsewhere were 4 percentage points more likely to drop out of secondary school and 5 percentage points less likely to obtain a bachelor's degree than children in nuclear families without fathers’ MPF. Resource competition due to economic and caregiving responsibilities for children living elsewhere does not explain the differences in educational outcomes. We do find that children in nuclear families whose fathers had previous childless marriages have educational outcomes that are similar to those of fathers with MPF. Our analysis suggests that the effects of fathers' MPF are primarily due to selection. Donna K.

Malleability and Intentional Activities

Whether people can sustainably change their level of happiness has been a topic of much debate in the psychological literature, with some researchers suggesting that happiness change is futile and others suggesting that it is quite possible, even if challenging. The current chapter reviews the literature on the major sources of happiness including genetics, life circumstances, and intentional activities, pointing to evidence of both stability and malleability in happiness over time. Although happiness is stable over time, evidence suggests that changes in certain life circumstances and the effortful practice of intentional happiness-increasing activities can shift happiness. Research also suggests that increases in happiness are not only valuable because they make life more pleasurable, but also because they trigger successful outcomes in other important life domains (e.g., improved relationships, work, and physical health). Although research on the potential downsides of over-valuing happiness serves as a warning for the excessive pursuit of happiness, research on prioritizing positivity paints a healthier version of happinessseekers who organize their daily lives around opportunities for greater happiness. Finally, intentional happiness-increasing activities—often called Positive Psychological Interventions—are discussed, including their mechanisms, moderators, and areas for future research. In sum, the research suggests that happiness change is possible, but not easy. Through persistent effort directed toward efficacious interventions, people can intentionally boost their happiness.
Palm-based Methyl Esters as Carrier Solvents in Pesticide Formulations

Pesticide formulations typically consist of active ingredients responsible for the pesticidal effect and inert ingredients responsible for improving product performance, stability and usability. Examples of inert ingredients include carrier solvents, emulsifiers, stabilisers, fragrances and dyes. The majority of pesticides are in the form of dry and liquid formulations. Examples of the former include dusts, granules, pellets and wettable powders while examples of the latter are solutions, aerosols, suspension concentrates or emulsions.
Lactic Acid Bacteria Inducing a Weak Interleukin-12 and Tumor Necrosis Factor Alpha Response in Human Dendritic Cells Inhibit Strongly Stimulating Lactic Acid Bacteria but Act Synergistically with Gram-Negative Bacteria

ABSTRACT The development and maintenance of immune homeostasis indispensably depend on signals from the gut flora. Lactic acid bacteria (LAB), which are gram-positive (G+) organisms, are plausible significant players and have received much attention. Gram-negative (G−) commensals, such as members of the family Enterobacteriaceae, may, however, be immunomodulators that are as important as G+ organisms but tend to be overlooked. Dendritic cells (DCs) are crucial immune regulators, and therefore, the present study aimed at investigating differences among human gut flora-derived LAB and G− bacteria in their patterns of DC polarization. Human monocyte-derived DCs were exposed to UV-killed bacteria, and cytokine secretion and surface marker expression were analyzed. Profound differences in the DC polarization patterns were found among the strains. While strains of LAB varied greatly in their capacity to induce interleukin-12 (IL-12) and tumor necrosis factor alpha (TNF-α), G− strains were consistently weak IL-12 and TNF-α inducers. All strains induced significant amounts of IL-10, but G− bacteria were far more potent IL-10 inducers than LAB. Interestingly, we found that when weakly IL-12- and TNF-α-inducing LAB and strong IL-12- and TNF-α-inducing LAB were mixed, the weakly IL-12- and TNF-α-inducing LAB efficiently inhibited otherwise strong IL-12- and TNF-α-inducing LAB, yet when weakly IL-12- and TNF-α-inducing LAB were mixed with G− bacteria, they synergistically induced IL-12 and TNF-α. Furthermore, strong IL-12- and TNF-α-inducing LAB efficiently up-regulated surface markers (CD40, CD83, CD86, and HLA-DR), which were inhibited by weakly IL-12- and TNF-α-inducing LAB. All G− bacteria potently up-regulated surface markers; however, these markers were not inhibited by weakly IL-12- and TNF-α-inducing LAB. These much divergent DC stimulation patterns among intestinal bacteria, which encompass both antagonistic and synergistic relationships, support the growing evidence that the composition of the gut flora affects immune regulation and that compositional imbalances may be involved in disease etiology.
Radiographic and functional results of osteosynthesis using the proximal femoral nail antirotation (PFNA) in the treatment of unstable intertrochanteric femoral fractures.

OBJECTIVES We evaluated the radiographic and functional results of the proximal femoral nail antirotation (PFNA) system in patients with unstable intertrochanteric femoral fractures. METHODS The study included 45 patients (25 women, 20 men; mean age 72 years; range 27 to 97 years) who underwent osteosynthesis using the PFNA for unstable intertrochanteric femoral fractures. The fractures were in the right hip in 25 patients, and in the left hip in 20 patients. The fractures were classified according to the AO system. One patient had an open fracture due to firearm injury (Gustilo-Anderson 3A). The patients underwent surgery within a mean of eight days (range 2 to 21 days) from injury. The mean hospital stay was 13.5 days (range 4 to 25 days). Closed reduction was achieved in all the patients. The results were assessed clinically and radiographically. The neck-shaft angle of the femur (collodiaphysial angle) and the tip-apex distance were measured. The position of the helical screw within the femoral head was determined using the method of Cleveland and Bosworth. Clinical evaluation was made using the Harris hip score. Perioperative and postoperative complications were recorded. The mean follow-up period was 17.3 months (range 6 to 23 months). RESULTS The mean operation time was 37.8 min (range 22 to 118 min) and the mean blood loss was 225 ml (range 150 to 450 ml). During surgery, femoral shaft fracture occurred in three patients, and greater trochanter fracture occurred in nine patients. Union was obtained in all the patients. Reduction was poor in four patients (8.9%), acceptable in seven patients (15.6%), and good in 34 patients (75.6%). The mean collodiaphysial angle was 136.7 degrees (range 125 degrees to 148 degrees). The tip-apex distance was <25 mm in 36 patients (80%), and =or>25 mm in nine patients (20%). The position of the helical screw in the femoral head was appropriate in 38 patients (84.4%). Postoperative complications included secondary varus (n=2, 4.4%), calcification at the tip of the greater trochanter (n=7, 15.5%), sensitivity over the fascia lata (n=7), medial thigh pain (n=11, 24.4%), and screw cut-out (n=1, 2.2%). Nine patients developed femoral shortness (mean 9.4 mm; range 8 to 13 mm). Screws showed lateral displacement in five patients (11.1%), which was less than 5 mm in four patients. Secondary surgery was required in four patients (8.9%). The mean Harris hip score was 77.8. Harris hip scores were very good in 11 patients (24.4%), good in 19 patients (42.2%), moderate in nine patients (20%), and poor in six patients (13.3%). CONCLUSION Due to advantages of high union rate, early postoperative mobilization, and short operation time, PFNA osteosynthesis is the method of choice for surgical treatment of unstable intertrochanteric femoral fractures.
Evolving role of FDG PET/CT in multiple myeloma imaging and management.

OBJECTIVE Multiple myeloma is the most common cause of primary malignancy in bones. Radiography has been the imaging reference standard for decades. However, the growing use of CT, MRI, and PET technology has led to earlier diagnosis of multiple myeloma, more accurate therapy assessment, and better prediction of patient outcome. This article is focused on the evolving role of (18)F-FDG PET/CT in multiple myeloma diagnosis, therapy assessment, and prognosis. CONCLUSION FDG PET/CT is a valuable imaging modality in diagnosis, therapy assessment, and prognosis of multiple myeloma.
Factors influencing work motivation of development agents : The case of Agarfa and Sinana Districts , Bale Zone , Oromia Regional State , Ethiopia

This study sets out to investigate the work motivation level of Development Agents (DAs) in Agarfa and Sinana Districts, Bale Zone, Oromia Regional State, Ethiopia and the factors that influence their motivation to work. For this study, all the Development Agents (a census of DAs) of the two districts with a total size of 135 DAs (Agarfa district, 67 and Sinana district, 68) were included as the sample respondents. Work motivation level of DAs was measured with a self-evaluation questionnaire. For the study, a structured survey questionnaire, focus group discussion and key informant interview were used to collect quantitative and qualitative data. In analyzing the data, both descriptive and inferential statistics were employed. The study found that a large majority of DAs (46.7%) belonged to medium level of work motivation, followed by 28.1% and 25.2% belonging to low and high level of work motivation, respectively. The findings thus highlight the importance of the investigation of the determinant factors contributing to the poor current work motivation status of DAs in the study area. Results of the descriptive statistics showed that of the total eighteen variables considered in the descriptive analysis, seventeen predictor variables, except age, were found to be of significance in explaining work motivation level of DAs. Based on the results of the study, relevant recommendations are forwarded in this report. Therefore, concerned agricultural extension managers, process owners, extension officers and supervisors should conduct periodic assessments to determine the level of work motivation of DAs and have to plan for improvement.
Effects of Cytokinin and Nitrogen on Drought Tolerance of Creeping Bentgrass

Cytokinin (CK) is a vital plant hormone that controls many aspects of growth and development in plants. Nitrogen (N) is the indispensable macronutrient needed in plants and also one of the most important limiting factors for plant growth. This study was designed to investigate the simultaneous effects of CK and N on the visual turf quality and antioxidant metabolism of drought-stressed creeping bentgrass (Agrostis stolonifera L.). ‘PennA-4’ creeping bentgrass treated with trans-zeatin riboside at three rates of CK concentrations of 0, 10 and 100 μM (designated by CK0, 10, and 100) and two nitrogen rates with 2.5 and 7.5 kg N·ha-1 every 15 days (designated by low and high N) in a complete factorial arrangement was grown under two soil moisture regimes: well-watered and drought stress. Exogenous CK improved turf quality and delayed leaf wilting under drought stress, especially under high N. The grasses treated with CK10 and CK100 had lower O2- production and H2O2 concentration than those without CK treatment. The CK100 treatment enhanced the activities of superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), and guaiacol peroxidase (POD) by 25%, 22%, 17% and 24%, respectively, relative to CK0. Moreover, the activity changes of the antioxidant enzyme isoforms were more significant under high N condition relative to low N condition. Our results demonstrated the beneficial impacts of CK and N on physiological reactions, especially antioxidant metabolism, and foliar application of CK at 10 or 100 μM plus 7.5 kg ha-1 N biweekly may improve drought stress resistance of creeping bentgrass.
Modal Analysis and Cutoff Condition of a Doubly Clad Cardioidic Waveguide

In this paper, we choose a simple and practical analytical method based on scalar wave approximation to study the modal behaviour, cutoff condition of a cardioidic doubly clad optical waveguide. The proposed waveguide is composed of three portions: the core, inner cladding, and outer cladding. It is assumed that the core has the largest refractive index of the three, and the outer cladding index is the next largest. We take the appropriate orthogonal coordinates for the proposed structure and impose the boundary conditions under the weak guidance approximation to get the modal eigen value equation. Using this equation we obtain numerical results in the form of dispersion curves and cutoff frequencies. An attempt has been made to estimate how the modal behaviour and cutoff conditions change as singly clad circular fiber to the doubly clad circular fiber. Keywords— waveguide, semiconductors lasers
Network Load balancing in Software Defined Network : A Survey

A variety of approaches have been suggested for data centers to balance network traffic in recent years. The network topologies and algorithm can affect the quality of the network communication. Routing algorithms such as a global load balancing (GLB) and dynamic load balancing (DLB) have been proposed. Both use fat-tree topology for data centers along with first using Software Defined Networking (SDN) architecture in cloud computing. TCP congestion window allows limited buffer space for data centers and cloud at a time. This paper presents a detailed survey on tasks performed on data centers & cloud environment and techniques which is used for load balancing on the network along with some algorithms used to improve the performance of overall network.
Filtering Documents over Time on Evolving Topics - The University of Amsterdam at TREC 2013 KBA CCR

In this paper we describe the University of Amsterdam’s approach to the TREC 2013 Knowledge Base Acceleration (KBA) Cumulative Citation Recommendation (CCR) track. The task is to filter a stream of documents for documents relevant to a given set of entities. We model the task as a multi-class classification task. Entities may evolve over time and the classifier should be able to adapt to these changes at runtime. To achieve this, the clas-sifier performs online self-learning, i.e., learning only from the examples it is most confi-dent about, based on a confidence score it produces for every prediction it makes.
AN INVESTIGATION INTO THE EFFECTIVENESS OF PERSONALITY TRANSCENDENCE TRAINING ON TEMPTATION RESISTANCE

Temptation resistance which is a kind of self-control and is known as a positive personality characteristic is vary from a person to others. The aim of this study was to investigate the effectiveness of teaching personality transcendence methods on temptation resistance. To conduct this experimental study, using random assignment, 44 Persian Gulf University students were divided into two groups. Participants at the experimental group received a 10-sesion personality transcendence training (one 90-minute session per week). After the intervention, all participants in both groups were administered the temptation resistance scenario. The results revealed increasing effect of teaching personality transcendence methods on temptation resistance. In this study, the effect of sublimation of character education practices to increase student resistance against temptation (eating sweets) from two independent samples t-test was used. And to evaluate the effect of sublimation of character education practices to increase student resistance against temptation (check out details and phone numbers of other students) were used Chi-square tests. The results showed a positive and significant difference between the control and experimental groups the temptation to eat sweets and other components the temptation to look at the address were observed.
Awareness of Preconception and Pregnancy Care among Bachelor Level Students of Dharan

Abstract: Preconception and pregnancy care is important for better pregnancy outcome. Awareness of both male and female is necessary for reducing maternal and neonatal morbidity and mortality in developing country like Nepal. The objective was to find out level of awareness on preconception and pregnancy care among bachelor level students of Dharan. Descriptive design was used for the study. Purposive sampling method was used to select 50 students from each college. Four colleges were selected through simple random sampling from 16 colleges and a total of 200 students who were studying bachelor final year were selected for study. Data were collected by self-administered Semi structured questionnaires. The result shows that 24.5% of total respondents heard about folic acid. Among them 7% were male respondents and 17.5% were female respondents. Majority (89%) of respondents accepts that male’s awareness is important for better pregnancy outcome. Female (mean awareness=55.2) were more aware than male (mean awareness=52.61) respondents on preconception and pregnancy care. Female were more aware on both preconception and pregnancy care. The source of information (media, newspaper) is associated with level of awareness. (p=0.010). Awareness level is related to employment status with higher proportion of employed individuals showing average awareness level (p=0.014). An equal to half (50.5%) of respondents have average awareness level on preconception and pregnancy care. The study concludes female (17.5%) have more good awareness level than male (7%) respondents.
Analyzing inter-firm networks for enhancing large-scale regional clusters

Dense networks among organizations are expected to work as a conduit of resources and knowledge within regional clusters. In this paper, we analyzed structures of large-scale inter-firm networks in the Kanto and Koshinetsu areas which include ten prefectures around Tokyo and are the largest economic blocks in Japan. We found a marked difference among prefectures in terms of the network structures, which can not be detected only by geographical factors and regional industries. The results give some important suggestions for the enhancement of large-scale regional clusters. The network structure showed that some prefectures are intensively developing their internal network connections while most of the prefectures are strongly connected to a center. The prefectures that are less connected to the center have a room to improve networking for the regional clusters. In addition, even among such prefectures, there is a clear difference in terms of their network positions. One prefecture has high network centralities and is maintaining certain amount of connections to other prefectures, which eventually contributes to economic revitalization in the whole areas. Another has less such external connections, which could raise a chance to accelerate the regional clusters by bridging such gap.
INTERNAL PROCESS , LEARNING PERSPECTIVE OF BALANCE SCORECARD AND ORGANISATIONAL PERFORMANCE A CASE OF TATA CHEMICALS MAGADI LIMITED , KENYA

The objective of this study was to determine the effect of internal process on organisational performance and to investigate the effect of growth and learning on organisational performance. The study adopted causal research design. Out of the target population of 350, a sample of 175 management level staff was selected comprised of 10 Heads of Department, 16 Managers and 149 Senior Staff. The study adopted stratified sampling techniques and from each stratum, simple random sampling techniques were adopted. Data collection was from primary and secondary sources. Primary data was gathered using Interview Guides and Questionnaires. Secondary sources included relevant documents and reports. Data was coded and clustered for subsequent statistical analysis. Linear regression analysis was used to test the hypotheses. Internal business process perspective (ß=0.771; t=5.870; ρ<0.001); and growth and learning perspective (ß=0.344; t=3.874; ρ<0.001); ρ<0.001). The multiple regression model expressing this relationship was significant (F= 28.186; P <0.001). The study therefore concluded that each of the two perspectives of the Balanced Scorecard had a positive relationship with organisational performance and could potentially increase the revenue base of the organisation. The study recommends that by adopting Balanced Scorecard the organisation will reduce product/service cost per unit and also reduce selling/general administration cost.
Operational Monitoring and Measurement Challenges in Large Scale WiFi Networks

We present our trials of WiFi monitoring and measurement with the currently implemented technologies in large-scale WiFi network operations. We then discuss the lacking technologies for the operators, regarding to the three WiFi networkspecific challenges; 1) handling the mutable client behavior due to the mobility, 2) monitoring spatio-temporal radio resource utilization, and 3) analyzing the interference on the shared resource. We believe the discussion and the practical problems raised in this paper will contribute the future design of monitoring standards and architectures.
