Corresponding Author Mai Farag Mohamed Hassanein Address: 7 Abd ElMoneim Eldalil street, Louran, Alexandria, Egypt. Email: mai.hassanein@yahoo.com Abstract Pneumonia is considered the most common cause of death due to infection among children under five. About 2 million episodes of pneumonia occur among children under 5 years old annually in Egypt The objectives of this study were to study the clinical characteristics of pneumonia patients and to evaluate the applied clinical practices in the management of these cases. This was done through prospectively collecting demographic and clinical details for pneumonia cases aged 29 days-15 years during the winter season of 2015-2016.It was found that among 130 subjects, the male-to-female ratio was 1:1, patients aged ≤ 2 years comprised 69.2% of the cases, the most common symptoms were cough and fever and 71.5% had co-morbid conditions. The most commonly used antibiotic was Ceftriaxone and most of the cases were treated using combined antibiotics. However, 11.5% died, while 22.3% had complications. The hospital stay duration had a mean of 6.92 ± 7.56 and the difference in mean hospital stay duration between cases of isolated pneumonia versus cases of pneumonia with an associated illness was statistically nonsignificant . This can lead to the conclusion that pneumonia is more common in infants and in children with co-morbid conditions and that pneumonia cases having other associated illnesses don't necessitate longer duration of hospital stay.
Overexpression of HDAC6 suppresses tumor cell proliferation and metastasis by inhibition of the canonical Wnt/β-catenin signaling pathway in hepatocellular carcinoma

Histone deacetylase 6 (HDAC6), a specific histone deacetylase family member, serves an essential role in the regulation of gene expression, cell cycle progression, autophagy and apoptosis. There are numerous reports on the function of HDAC6 in cancer. However, the specific function of HDAC6 in hepatocellular carcinoma (HCC) has yet to be revealed. In the present study, the expression of HDAC6 was revealed to be downregulated in human HCC cell lines and tissues. The aberrant activation of the canonical Wnt/β-catenin signaling pathway was revealed to be involved in hepatocarcinogenesis and metastasis. It was additionally revealed that the overexpression of HDAC6 decreased the expression of β-catenin protein levels which attenuated the canonical Wnt/β-catenin signaling pathway and suppressed the proliferation of HCC cells. In addition, the upregulation of HDAC6 inhibited the epithelial-to-mesenchymal transition in HCC by increasing the E-cadherin protein levels and decreasing the N-cadherin, vimentin and matrix metalloproteinase-9 protein levels. Furthermore, HDAC6 also exerted an effect on the cell cycle arrest and the induction of apoptosis. These results demonstrated that HDAC6 functioned as a tumor suppressor in HCC by attenuating the activity of the canonical Wnt/β-catenin signaling pathway. Therefore, HDAC6 may serve as a potential therapeutic target for the treatment of HCC.
EFFICACY OF KETONES ON THE FORAGING BEHAVIOUR OF APIS FLOREA F. IN FIELD CONDITIONS

Three ketones (methyl propyl ketone, benzyl methyl ketone and methyl pentyl ketone) were tested on onion (Allium cepa) and three (methyl pentyl ketone, ethyl propyl ketone and ethyl pentyl ketone) were screened on carrot (Daucus carota) under field conditions for their repellent action against Apis florea F. The number of bees visiting the control and treated crop plants was recorded. The effect of repellents decreased with the passage of time (Figs 1-6). Field experiments clearly demonstrated that the duration of stability of ketones is greater on D. carota than on A. cepa. Clearly, temperature is the main influential factor in the determination of repellent effect ; relative humidity acts as a balancing factor (Table 1).

Fine and Hyperfine Structure in the Spectrum of Secular Variations of Atmospheric 14C

The coarse structure of the 14C spectrum consists of a secular trend curve that may be closely fit by a sinusoidal curve with period ca 11,000 yr and half amplitude ±51. This long-term trend is the result of changes in the earth's geomagnetic dipole moment. Consequently, it modulates solar components of the 14C spectrum but does not appear to modulate a component of the spectrum of ca 2300-yr period. The ca 2300-yr period is of uncertain origin but may be due to changes in climate because it also appears in the δ18O spectrum of ice cores. This component strongly modulates the well-known ca 200-yr period of the spectrum's fine structure. The hyperfine structure consists of two components that fluctuate with the 11-yr solar cycle. One component results from solar-wind modulation of the galactic cosmic rays and has a half-amplitude of ca ±1.5. The other component is the result of 14C production by solar cosmic rays that arrive more randomly but rise and fall with the 11-yr cycle and appear to dominate the fluctuation of the galactic cosmic-ray-produced component by a factor of two.
Organizational adaptation to interdependence shifts: The role of integrator structures

Research summary: We investigate how organizational adaptation to interdependence shifts is influenced by “integrators. ” These are formally mandated managerial roles meant to promote coordination across specialized but interdependent organizational subunits, yet they do so without relying on formal authority. While much has been learned about how integrators promote steady-state coordination within a known pattern of interdependence, less is known about their impact on organizational adaptation when the pattern of interdependence itself is unknown. We discuss mechanisms by which integrators may nonetheless aid organizational adaptation and learning processes in such situations, and test our hypotheses in the context of a regulatory change that affected the in vitro fertilization (IVF) clinics sector in the United Kingdom using a differences-in-differences design. Managerial summary: Organizational structure can influence how an organization adapts to change. We investigate how a regulatory change in the provision of fertility treatments in the United Kingdom forced clinics to change their workflows, and whether the presence of integrator roles enabled clinics to adapt to these changes. It is well known that integrator roles in general are valuable in coordinating across specialized organizational units, but this research points to the surprising implication that their value may persist even when the workflow being coordinated changes suddenly, in ways that nobody necessarily comprehends. Our research highlights the fact that even in an intensively science-based work context, the “technology of organizing” can have a significant role in shaping organizational performance.

An investigation into the relationship between celebrity attitudes, social comparison and social media use

"The study aimed to investigate further the area of celebrity worship due to research suggesting mental health implications for people who have intense Parasocial relationships with celebrities. In addition, Celebrity worship was studied in relation to social media use and social comparison as this is a relatively unexplored area in Psychology. An opportunity sample of 103 volunteers completed an online questionnaire investigating the 3 variables. A multiple regression analysis was then used to analyse the data. It was found that the multiple regression model was not significant and therefore none of the predictor variables; social media use and social comparison, were significant predictors of the criterion variable; celebrity worship. Therefore, the studies hypotheses; “There will be a correlation between social media use and level of celebrity worship” and “This relationship will be related to scores on the social comparison orientation scale” were rejected as there was no significant relationship found between the variables. Based on the findings from this study, it is suggested that future research investigates the effect of above average social media use and in particular the influence that peer relationships can have on an individual or group regarding social comparison.
Statistical analysis of the very quiet Sun magnetism

The behavior of the observed polarization amplitudes with spatial resolution is a strong constraint on the nature and organization of solar magnetic fields below the resolution limit. We study the polarization of the very quiet Sun at different spatial resolutions using ground- and space-based observations. It is shown that 80% of the observed polarization signals do not change with spatial resolution, suggesting that, observationally, the very quiet Sun magnetism remains the same despite the high spatial resolution of space-based observations. Our analysis also reveals a cascade of spatial scales for the magnetic field within the resolution element. It is manifest that the Zeeman effect is sensitive to the microturbulent field usually associated to Hanle diagnostics. This demonstrates that Zeeman and Hanle studies show complementary perspectives of the same magnetism.
Bachelorthese EEG representation of emotion evoking pictures

The present study examined induced emotions via emotiogenic pictures (from the International Affective Picture System) in a spectral analysis of electroencephalographic (EEG) data. Evidence contributing to theories which link prefrontal right sided activity to negative emotion and left sided activity to positive emotions could be found in form of alpha2 (10-13Hz) desynchronization as well as tendencies for alpha1 (8-10Hz), delta (1-4Hz) and theta1 (4-6Hz) asynchronies only. Increasing beta1 (13-20Hz) activity in both hemisphere over parietal areas and increasing left sided gamma (30-50Hz) activity over parietotemporal areas also significantly distinguished emotional states but not in line with introduced theory.
The Off-Farm Labour Force Participation of Mayo Farm Households

The objective of this paper is to examine the factors affecting both participation in an off-farm job and the number of hours worked off-farm by couples in farm households in an Irish region. Data from 278 farm households in Co. Mayo was analysed to this end. A multivariate examination of key characteristics, using cluster analysis, was carried out to classify households into different clusters. The analysis comes reasonably close to picking out the four regimes suggested by the presented theoretical model, that is a cluster in which neither the operator or spouse work off-farm, one in which only the spouse works off-farm, one in which only the operator works off-farm, and one in which both work off-farm. This analysis is followed by an econometric analysis of farm operator and spouse labour supply decisions. Both bivariate probit models and multivariate logit models are used to estimate the off-farm labour force participation of operators and spouses. The participation models are followed by estimations of off-farm hours of work supplied by the couple, using appropriate sample selection procedures. For operators, the driving characteristics influencing off-farm labour participation and hours supplied are farm and location characteristics. In contrast, family demographics and education level appear to influence off-farm labour participation and hours supplied by the spouse.
The Profits-Leverage Puzzle Revisited

The inverse relation between leverage and profitability is widely regarded as a serious defect of the trade-off theory. We show that the defect is not with the theory but with the use of a leverage ratio in which profitability affects both the numerator and the denominator. Profitability directly increases the value of equity. Firms do take the predicted offsetting actions. They issue debt and repurchase equity when profitability rises, and retire debt and issue equity when profitability falls. Consistent with variable transactions costs, the adjustment is not generally sufficient to fully undo the profitability shocks. Accordingly, on average the leverage ratio falls as profitability rises.
Partitioning of formaldehyde between gas phase and particles (PM2.5) in México City

An annular denuder/filter-pack sampling technique has been employed to get an insight of the formaldehyde partitioning between gas phase and particles (PM2.5) in Mexico City using short time sampling periods. Formaldehyde was trapped using DNPH derivatives and analyzed by HPLC/UV. One annular denuder was used to trap formaldehyde from the gas phase followed by a Teflon filter to trap PM2.5, and a second backup denuder was used to trap degassed formaldehyde from the filter. Just after finishing the sampling, filters were soaked in a DNPH solution to fix the PM2.5 formaldehyde, and the denuders where extracted with another DNPH solution. The sum of the concentrations in both phases ranged from 7.90 to 44.60 µg/m 3 during the
Detection Model of Legally Registered Mafia Firms in Italy

This paper develops a model that can contribute to the detection of legally registered firms defined as Mafia firms (LMFs) due to having been confiscated by judicial authorities, in relation to alleged connections of their owners with Italian organized crime. The model correctly classifies 76.41% of firms within a matched sample of 852 firm-years including LMFs and lawful firms. Furthermore, we present an analysis of financial statement characteristics of singular private firms which are socially irresponsible by nature and whose incentives, modus operandi and legal financial statement formats differ from those of listed companies. In particular, we show that specific accruals and earnings management proxies may provide more insight into accounting manipulation patterns of LMFs. More importantly, our paper can help practitioners and regulators identify accounting signals that can be used in risk assessment models or in the detection of criminal infiltrations and related illicit practices.
The relationship between emotional intelligence and stress management

Regardless of where one lives in the world, one cannot escape three defi ning forces of our time: globalisation, the information revolution and the speed of change (Cascio, 2001). To ensure continued organisational performance and to maintain the competitive advantage, organisations must therefore constantly implement changes in strategy, structure, process and culture (Higgs, 2002; Langley, 2000). Goleman (1998) proposes a solution of self-awareness as a key skill in handling stress, thereby indicating that a lack of emotional intelligence in such an unstable environment means possible failure that can impact on everyone’s future. The general aim of this research was to determine whether there is a relationship between emotional intelligence and stress management in a group of managers. This was done through a quantitative study of the relationship between stress management and emotional intelligence. These constructs were operationalised by means of a combination of scales present in the Feelings and Emotions domain of the Occupational Personality Questionnaire (OPQ32i) and the Emotional Quotient Inventory (Bar-On EQ-i). The correlation and regression results seem to indicate that stress management (the ability to cope with stress) is a component of emotional intelligence, while stress can be either an input or an outflow of emotional intelligence or the lack thereof .
Solar radiation at the surface in the Baltic Proper

Radiation data recorded at 12 sites around the central part of the Baltic Sea during 1996–2000 drawn from the BALTEX (Baltic Sea Experiment) meteorological data archives are used to study the spatio-temporal variability of daily global radiation totals. The annual average daily global radiation total varies from about 10MJ m at Visby (on Gotland) and Kołobrzeg (on the coast of Poland) to less than 9 MJ m at Z̄ılāni (inland Latvia), Šilutė (Lithuania) and Jokioinen (Finland). The monthly average daily global radiation total over the whole region extends from 0.93 in December to 19.0 in June. The variability in global radiation is analysed on the basis of the fraction of the daily total at the top of the atmosphere. The spatial and temporal variability is the least in August – this shows that the variation in the cloud cover and atmospheric properties at this time of year is the smallest. The spatial correlation is the strongest between the two Finnish stations * This research was supported by targeted financing from the Estonian Ministry of Education and Science (grant SF0140017s08). Radiation data were drawn from the BALTEX meteorological data archive. The complete text of the paper is available at http://www.iopan. gda.pl/oceanologia/ 584 S. Keevallik, K. Loitjärv – Vantaa and Jokioinen. It is also high between Stockholm and Norrköping, on the east coast of Sweden. The correlation coefficients are the largest over the whole area in April. Radiation data from coastal stations are compared with an earlier parameterization based on ship observations (Rozwadowska & Isemer 1998, Isemer & Rozwadowska 1999). It is concluded that in climatological research, actinometric data from Visby can be used to characterize the radiation field over the northern part of the Baltic Proper and those from Kołobrzeg to characterize the radiation field over the southern part of this sea.
Risk, factor substitution, and asset market integration

This paper investigates the effects of asset market integration on the inequality of nations. The standard OLG economy with a neoclassical technology is extended to include a random exogenous technology (Lucas’ tree) whose ownership can be traded in the form of paper assets. A world with two such economies is considered which differ only in their initial capital stocks. If asset demand is sufficiently inelastic, the poor country may spend more income in purchasing paper assets than the rich country. In this case, an integration of asset markets alone can prevent capital stocks in the two countries from converging to the same level in the long run, i. e. symmetry breaking occurs. However, if capital and labor are highly substitutable, capital converges to a symmetric steady state.
The physiological response of Saccharomyces cerevisiae to temperature stress

Gist speelt een belangrijke rol in de voedingsmiddelenindustrie. Tijdens de productie ervaart een gistcel grote veranderingen in de omgeving. Een van die veranderingen is de temperatuur. Jarne Postmus onderzocht wat de gevolgen zijn van een veranderde temperatuur op de suikerafbrekende reactie van een gistcel, en vooral welke processen deze veranderingen tot stand brengen. De reactiesnelheid kan veranderen door veranderde concentraties van de enzymen, door een activiteitsverhogend effect van de temperatuur op de enzymen en door omgevingsfactoren van de enzymen. Het blijkt dat de snelheid waarmee glucose wordt afgebroken hoger is bij hoge temperatuur. En dat de manier waarop deze verhoging tot stand is gekomen, op verschillende manieren is gereguleerd, afhankelijk van de manier waarop de gistcel groeit. Tevens bestudeerde Postmus het functioneren van de mitochondrien (de energiefabriekjes in de cel) op verhoogde temperatuur. Hij concludeert dat de efficientie van mitochondrien groter wordt bij een verhoging van de temperatuur. Postmus identificeerde het eiwit dat verantwoordelijk is voor deze verhoging. Bij temperaturen hoger dan 37 graden is de efficientie juist heel laag. Waarschijnlijk door een opstapeling van schade gaan de mitochondrien stuk en zoekt de cel een andere manier om ATP (energie) te genereren.
Investigation of Over-Permeable Superpave Surface Mixes in North Carolina

Bacchi, Christopher. Investigation of Over-Permeable Superpave Surface Mixes in North Carolina. (Under the direction of Dr. Ahktar Tayebali, Ph.D, PE) Superpave was introduced in 1994, as a result of the Strategic Highway Research Program (SHRP) and was aimed at addressing the performance of asphalt concrete pavements. This SHRP study recommended new specifications for asphalt mixture designs which included performance graded binders, performance related aggregate properties, and new principles for volumetric mix designs. With these new mix design principles, it was evident that Superpave mix designs would contain more coarse aggregates and less natural sands. With the introduction of Superpave, many in the Asphalt industry feared that the recommended coarse structured mixes would be very difficult to compact and highly permeable compared to the Marshall mixes they were replacing. In North Carolina, we have seen instances where this theory was proven true and have witnessed coarse Superpave mixes that have been permeable. In general, the cause of this permeability may be due to increased voids caused by improper compaction that results from the coarse nature of the designs, which in turn creates interconnected voids that will transmit water through the pavement. A remedy to the permeability problem may be a new test that can determine in the laboratory if certain mixes are susceptible to permeability. This test is discussed in this study. The data represented in this study shows the causes of permeability in a small group of pavements that were sampled and should not be misinterpreted to imply that this small number of distressed pavements is indicative of all Superpave mixes. The selected mixes are a cross section of surface mixes used across the State of North Carolina. The permeability test method discussed in this study is a very simple procedure and the data presented show that this test can be used for predicting field permeability of Superpave surface mixtures. The coarse graded mixes performed poorly in the lab permeability tests and the fine graded mixes proved to be very impermeable. This study also evaluated mixes using laboratory performance tests. The results show that the coarse graded mixes and fine graded surface mixes perform equally well under laboratory performance testing at a given void content that matches the in-situ properties. Using these lab tests and the results of this study, a clearer understanding of the effects of water in asphalt pavements and how to prevent this water infiltration has been obtained and new specification changes have been recommended to reduce any future permeability problem with Superpave surface mixes.
