Published: February 2013

AbstractThe Mellin transform is a mathematical tool which has been applied in many areas of Mathematics, Physics and Engineering. Its application in Geophysics is in the computation of solution of potential problems for the determination of the mass as well as the depth to the basement of some solid mineral deposits. In this study, the Mellin transform is used to determine the depth to the top (h) and the depth to the bottom (H) of the basement of a profile of an anomalous magnetic body. Ibuji, the study area is located in Ifedore Local Government area of Ondo state, Nigeria, underlain by Precambrian complex rocks and bounded by geographical co-ordinate of Easting 5°00t’00″ to 5°4t’30″ and Northing 7°24t’00″ to 7°27t’36″. The magnetic anomaly profile due to a two- dimensional body(vertical thin sheet)over magnetic spring of the study area was digitised and the values of magnetic amplitude (nT) with respect to its horizontal distance (say interval of 5 m) obtained from the digitized profile was then used in the computation of Mellin transform using Matlab programs. In order to determine the depths H and h, the amplitudes were considered at three arbitrary point (s = ¼, ½ and ¾) such that, (0 < s < 1), where s is a complex variable of real positive integer. The value obtained for H was 47.95 m, which compared favourably with the result obtained using other methods. Meanwhile, the value obtained for h has a convergence restriction, whereby, at lower values of s, there is divergence, while at higher values of s, (about 0.9), the result converges and h was obtained to be 32.56 m. The Ibuji magnetic anomaly was therefore analysed to have a depth to the bottom (H) of 47.95 m and depth to the top of 32.56 m using this mathematical tool.

ABSTRACT
Zapalski, M.K. and Berkowski, B. 2012. The oldest species of ?Yavorskia (Tabulata) from the Upper Famennian of the Holy Cross Mountains (Poland). Acta Geologica Polonica, 62 (2), 197-204. Warszawa. A single perfectly preserved colony of a tabulate coral assigned tentatively to the genus Yavorskia Fomitchev, 1931, collected from Upper Famennian beds (Palmatolepis expansa conodont Zone) in a trench located north of the Kowala Quarry (Holy Cross Mts., central Poland) is here described as a new species, ?Y. paszkowskii sp. nov. It differs from other representatives of the genus in the lack of dissepimental structures and in smaller corallite diameters, and may therefore represent the ancestral taxon of this typically early Carboniferous genus. Yavorskia tabulates were apparently migrating eastwards along the southern margin of Laurussia and farther east and north towards Siberia, as they appear in the Famennian in Europe and in the early Carboniferous in the Altaides. Such a conclusion is consistent with previous observations on Early-Middle Devonian pleurodictyform tabulate distribution.
Effects of Cr - Ni 18/9 Austenitic Cast Steel Modification by Mischmetal

Published: February 2013

Abstract
This paper presents the results of Cr - Ni 18/9 austenitic cast steel modifications by mischmetal. The study was conducted on industrial melts. Cast steel was melted in an electric induction furnace with a capacity of 2000 kg and a basic lining crucible. .The mischmetal was introduced into the ladle during tapping of the cast steel from the furnace. The effectiveness of modification was examined with the carbon content of 0.1% and the presence of δ ferrite in the structure of cast steel stabilized with titanium. The changes in the structure of cast steel and their effect on mechanical properties and intergranular corrosion were studied. It was found that rare earth metals decrease the sulfur content in cast steel and above all, they cause a distinct change in morphology of the δ ferrite and non-metallic inclusions. These changes have improved mechanical properties. R02, Rm, and A5 and toughness increased significantly. There was a great increase of the resistance to intergranular corrosion in the Huey test. The study confirmed the high efficiency of cast steel modification by mischmetal in industrial environments. The final effect of modification depends on the form and manner of placing mischmetal into the liquid metal and the melting technology, ie the degree of deoxidation and desulfurization of the metal in the furnace.
Evaluation of Anthropometric Indices for Metabolic Syndrome and their Association with Metabolic Risk Factors among Healthy Individuals in New Belgrade

Summary
People with metabolic syndrome (MetSy) are about twice as likely to develop cardiovascular disease and over four times as likely to develop type 2 diabetes compared to subjects without metabolic syndrome. Waist circumferences (WC) and body mass index (BMI) are useful screening tools for making the diagnosis. MetSy has increased the health risk in primary care. The aim of the study was to evaluate the anthropometric indices for MetSy and determine which of simple anthropometric measurements is most closely associated with metabolic risk factors.
The research included 264 individuals, of which 132 men with mean age (±SD) of 44.73 ±9.37 years and 132 women with mean age (±SD) of 46.67±8.44 years. Antropometric indicators were measured using standard protocols, without shoes and outerwear. BMI was calculated as weight/height2(kg/m2) ratio, as recommended by the World Health Organization (WHO). Blood pressure measurements were obtained with the subject in a seated position by using a standard mercury sphygmomanometer. Blood samples were obtained after a minimum of 12-h fast; the metabolic parameters (high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, triglycerides, blood glucose) were analyzed by standard procedures. Analysis of the examinees’ medical records was also performed. Metabolic syndrome was diagnosed using the International Diabetes Federation (IDF) criteria. The analysis of the research results were performed using the Statistical Package for Social Science version 10.0 (SPSS 10.0 for Windows).
The prevalence of the metabolic syndrome was 44.7% in men and 43.2% in women. Normal-weight subjects of both sexes were significantly younger and had significantly lower blood glucose, total cholesterol, LDL and triglycerides than overweight and obese subjects. Systolic and diastolic blood pressure values were significantly increased in parallel with increasing of BMI. For the whole sample, both anthropometric indices had significant associations with the other five components of MetSy.
Waist circumference is a simple measure of adiposity most strongly associated with metabolic abnormalities. The results obtained in this study indicate that WC is a good indicator of health risk in women but not in men. Measurement of WC by BMI categories may indicate a person with an increased risk of development of chronic diseases.

Authors: Zakis Janis , Vinnikov Dmitri 
Published: February 2013

Abstract
Focus is on implementation possibilities of surfacemount device (SMD) to be used in high power applications. SMD capacitors reduce the size and dimensions of a power circuit and increase the flexibility of placement of other components. Ceramic and electrolytic capacitors are compared by means of voltage ripple, volume, labour-intensity and impedance. A 1 kW experimental setup of a quasi-Z-Source inverter (qZSI) based converter was built to compare SMD capacitor performance in the quasi-Z-source (qZS) network.

Protracted Port-site Infection: A Dilemma
Authors: Mukhopadhyay Partha , Goswami Sebanti , Kapoor Nandini 
Published: February 2013

ABSTRACT

Objectives
From simple beginnings, laparoscopic surgery has now been completely integrated into the field of gynecological surgery. Infection of the port site is an infrequent complication of laparoscopy. The causative organisms of this infection are usually those which are most prevalent in the institute, e.g. S.aureus, E.coli. These types of infections are easily treated by the antibiotics which are most commonly prescribed in the institute. Sometimes, these port-site infections become protracted and recurrent and pose as a dilemma for the surgeons and become distressing for the patients.

Materials and methods
A prospective longitudinal study was conducted on 25 patients presenting to the OPD with recurrent discharge or nonhealing port-site wound following laparoscopic surgery done in our institute. These patients underwent a battery of test including detailed microbiological examination. The discharge from their port site was sent for routine aerobic culture and sensitivity. It was also sent for Z-N stain and culture for Mycobacterium including atypical Mycobacterium.

Results
Out of the 25 patients studied, 16 showed presence of AFB bacilli in their discharge and the culture for Mycobacterium showed presence of Atypical Mycobacterium in 12 cases. Out of the remaining nine patients, six showed a growth of S. aureus on aerobic culture and the remaining patients had a growth of E. coli.

Conclusion
Atypical Mycobacterium is the most common causative organism of recurrent port-site infection in our institute. This type of infection then require a full course of antituberculous drugs for complete eradication. So, when treating a case of nonhealing or recurrent port-site infection, atypical Mycobacterium infection should be kept in mind.

Formation and characterization of perfluorocyclobutyl polymer thin films
Authors: Zhou Jinxiang , Jin Jianyong , Haldeman Adam T. , Wagener Earl H. , Husson Scott M. 
Published: February 2013

AbstractPerfluorocyclobutyl (PFCB) polymers are a new class of materials that show promise as selective layer materials in the development of composite membranes for gas separations, such as carbon dioxide/methane (αpure gas = 38.6) and oxygen/nitrogen (αpure gas = 4.8) separations. In many of the flat sheet applications, a thin film of the selective layer that is free of major defects must be coated onto a support membrane. A focus of this study was to elucidate the impacts of solvents, polymer concentration, and dip‐coating withdrawal speed on PFCB thin film thickness and uniformity. An extension was proposed to the Landau–Levich model to estimate the polymer film thickness. The results show that the extended model fits the thickness‐withdrawal speed data well above about 55 mm/min, but, at lower withdrawal speeds, the data deviated from the model. This deviation could be explained by the phenomenon of polymer surface excess. Static surface excesses of polymer solutions were estimated by applying the Gibbs adsorption equation using measured surface tension data. Prepared films were characterized by ellipsometry. Refractive index was found to increase with decreasing film thickness below about 50 nm, indicating densification of ultrathin films prepared from PFCB solutions below the overlap concentration. Atomic force microscopy was used to characterize surface morphologies. Films prepared from tetrahydrofuran and chloroform yielded uniform nanolayers. However, films prepared using acetone as solvent yielded a partial dewetting pattern, which could be explained by a surface depletion layer of pure solvent between the bulk PFCB/acetone solution and the substrate. © 2013 Wiley Periodicals, Inc.

Electron Capture by the Thiyl Radical and Disulfide Bond: Ligand Effects on the Reduction Potential
Authors: Roos Goedele , De Proft Frank , Geerlings Paul 
Published: February 2013

AbstractThe effect of non‐polar and polar ligands and of monovalent cations on the one‐electron reduction potential of the thiyl radical and the disulfide bond was evaluated. The reduction potentials E° for the CH3S.–n L/CH3S−–n L and CH3SSCH3–L/CH3SSCH3.−–L redox couples were calculated at the B3LYP, M06‐2X and MP2 levels of theory, with n=1, 2 and L=CH4, C2H4, H2O, CH3OH, NH3, CH3COOH, CH3CONH2, NH4+, Na+, K+ and Li+. Non‐polar ligands decrease the E° value of the thiyl radical and disulfide bond, while neutral polar ligands favour electron uptake. Charged polar ligands and cations favour electron capture by the thiyl radical while disfavouring electron uptake by the disulfide bond. Thus, the same type of ligand can have a different effect on E° depending on the redox couple. Therefore, properties of an isolated ligand cannot uniquely determine E°. The ligand effects on E° are discussed in terms of the vertical electron affinity and reorganization energy, as well as molecular orbital theory. For a given redox couple, the ligand type influences the nature of the anion formed upon electron capture and the corresponding reorganization process towards the reduced geometry.

AbstractA direct asymmetric substitution was developed for the reaction of cyclic Morita–Baylis–Hillman alcohols with 3‐benzyl‐2‐oxindoles that are catalyzed by a primary amine derived from alkaloids in combination with trifluoroacetic acid. The unusual δ‐products with vicinal chiral quaternary and tertiary carbon centers were obtained as the major products in yields up to 73 % with excellent diastereoselectivities (up to 99:1) and enantioselectivities (up to 98 % ee).

Published: February 2013

AbstractThe combined effects of climate warming (i.e., increased storminess, reduced sea ice extent, and rising sea levels) make low‐lying Arctic coastal regions particularly susceptible to storm surges. The Mackenzie Delta, a biologically significant and resource‐rich region in northwestern Canada, is particularly vulnerable to flooding by storm surges. To properly manage the consequences of climate warming for Arctic residents, infrastructure, and ecosystems, a better understanding of the influence of climate change on storm surge activity is required. Here we use particle size analysis of lake sediment records to show that the occurrence and magnitude of storm surges in the outer Mackenzie Delta are significantly related to temperature and that the frequency and intensity of storm surges is increasing. Our results demonstrate the effects of changing climate on storm surge activity and provide a cautionary example of the threat of inundation to low‐lying Arctic coastal environments under future climate warming scenarios.
A FUNCTIONAL ANALYSIS OF CRYING
Authors: Bowman Lynn G. , Hardesty Samantha L. , Mendres‐Smith Amber E. 
Published: February 2013

AbstractCrying has yet to be examined systematically in isolation from other problem behavior, such as aggression or tantrums, during functional analyses (Hanley, Iwata, & McCord, 2003). Identification of variables that may maintain crying is especially important for populations who are susceptible to psychiatric interventions (e.g., individuals who have intellectual disabilities and communication deficits). The current study extended functional analysis methodology to crying with an adolescent boy who had been diagnosed with intellectual disabilities. Results suggested that crying was maintained by caregiver attention delivered in a sympathetic manner.

Published: February 2013

AbstractMedical school training for students in pharmacotherapy is suboptimal and junior doctors are not confident to prescribe drugs. This study evaluated the effectiveness of an optional educational intervention on prescribing skill of pre‐clerkship medical students in a problem‐based learning (PBL) program. Performance was assessed in seven end‐unit objective structured practical examinations (OSPE). Physician‐related prescription components (PRCs) and drug‐related prescription components (DRCs) were assessed. The performance of students who attended the intervention sessions (attendees) and non‐attendees was compared. Approximately half of the students attended the sessions. PRCs were written appropriately by most of the students. DRCs were written less competently by both attendees and non‐attendees, specifically the dosage form, quantity to be dispensed and directions. Performance on individual DRCs was significantly better for attendees compared to non‐attendees. The mean total score for all prescription components of attendees was significantly greater than that of non‐attendees. The percentage of high achievers was significantly greater for attendees. A positive correlation was found between student attendance and the total score. An optional educational intervention during the preclerkship phase is an important determinant of prescribing performance of medical students.
Reliability of spike triggered averaging of the surface electromyogram for motor unit action potential estimation
Authors: Hu Xiaogang , Rymer William Z. , Suresh Nina L. 
Published: February 2013

ABSTRACTIntroduction: The reliability of estimated motor unit parameters using spike triggered averaging (STA) of the surface electromyogram (sEMG) has not been tested thoroughly. We investigated factors that may induce amplitude bias in estimated motor unit action potentials (MUAPs) and shape variations. Methods: An sEMG record was simulated. MUAPs were then estimated from the STA of the simulated EMG. Results: Variations in MUAP duration led to under‐estimation of real MUAP amplitude, while synchronized firing led to over‐estimation of amplitude. Spurious firing resulted in over‐estimation of the amplitude of small motor units but under‐estimation of the amplitude of large ones. Variability in amplitude and high firing rates had minimal influence on amplitude estimation. High firing rates and variation in MUAP duration led to large variations in MUAP shape. Estimation errors also correlated with shape variations. Conclusions: Recommendations to enhance the accuracy of the STA estimates have been proposed. Muscle Nerve 48: 557–570, 2013
Die intermediären Bosonen der schwachen Wechselwirkung — und was kommt dann?

Published: February 2013

AbstractUnser Kosmos baut sich aus einigen wenigen kleinsten Bestandteilen, den Quarks und Leptonen, auf. Alle physikalischen Phänomene lassen sich auf vier Grundkräfte zwischen diesen vielleicht elementaren Teilchen zurückführen. Die Physiker sind bestrebt, eine übergreifende Theorie für die vier Grundkräfte zu formulieren und sie auf eine einzige Kraft zurückzuführen. Die Entdeckung der schweren intermediären Vektorbosonen, der Kraftquanten der schwachen Wechselwirkung, stellt einen Meilenstein auf dem Weg zu dieser Vereinheitlichung dar.
Die Diskretisierung der Maxwell‐Gleichungen: Ein allgemeines Verfahren zur Berechnung elektromagnetischer Felder und seine Anwendung in Physik und Technik
Authors: Weiland Thomas 
Published: February 2013

AbstractDie Lösung der Maxwellschen Gleichungen bedeutet eine immer wiederkehrende Aufgabe bei der Konstruktion elektromagnetischer Apparaturen. Einerseits bereiten die komplizierten Strukturen realer Geräte oft unüberwindbare Schwierigkeiten, andererseits nimmt die Bedeutung einer genauen Vorhersage der elektromagnetischen Felder mit der Größe und dem Herstellungsaufwand der Geräte zu. Anlagen für die Hochenergiephysik beispielsweise haben Ausmaße erreicht, die nur noch den einmaligen Bau einer Apparatur erlauben. Mit Hilfe eines einzigen Lösungsansatzes ist es möglich, die Maxwell‐Gleichungen einzeln in entsprechende Matrixgleichungen umzuformen, die auf modernen Großrechnern gelöst werden können. Das Verfahren erlaubt es, beliebig geformte Körper mit beliebigen Materialeigenschaften zu behandeln; es ist in vielen Bereichen der Physik und Technik anwendbar. Die Bedeutung solcher Lösungsverfahren für die Entwicklung von Beschleunigern in der Hochenergiephysik wird an einigen Beispielen aufgezeigt.
