Objective The main objective of this study was to assess mother-child patterns of interaction in relation to later quality of attachment in a group of children with an orofacial cleft compared with children without cleft. Design Families were contacted when the child was 2 months old for a direct assessment of mother-child interaction and then at 12 months for a direct assessment of the child's attachment. Data concerning socioeconomical information and posttraumatic stress symptoms in mothers were collected at the first appointment. Participants Forty families of children with a cleft and 45 families of children without cleft were included in the study. Families were recruited at birth in the University Hospital of Lausanne. Results Results showed that children with a cleft were more difficult and less cooperative during interaction at 2 months of age with their mother compared with children without a cleft. No significant differences were found in mothers or in dyadic interactive styles. Concerning the child's attachment at 12 months old, no differences were found in attachment security. However, secure children with a cleft were significantly more avoidant with their mother during the reunion episodes than secure children without cleft. Conclusion Despite the facial disfigurement and the stress engendered by treatment during the first months of the infant's life, children with cleft and their mothers are doing as well as families without cleft with regard to the mothers' mental health, mother-child relationships, and later quality of attachment. A potential contribution for this absence of difference may be the pluridisciplinary support that families of children with cleft benefit from in Lausanne.

Abstract
Cervical cancer is preventable but continues to cause the deaths of more than 270,000 women worldwide each year, most of them in developing countries where programs to detect and treat precancerous lesions are not affordable or available. Studies have demonstrated that screening by visual inspection of the cervix using acetic acid (VIA) is a simple, affordable, and sensitive test that can identify precancerous changes of the cervix so that treatment such as cryotherapy can be provided. Government partners implemented screening and treatment using VIA and cryotherapy at demonstration sites in Peru, Uganda, and Vietnam. Evaluations were conducted in the three countries to explore the barriers and facilitating factors for the use of services and for incorporation of screen-and-treat programs using VIA and cryotherapy into routine services. Results showed that use of VIA and cryotherapy in these settings is a feasible approach to providing cervical cancer prevention services. Activities that can help ensure successful programs include mobilizing and educating communities, organizing services to meet women's schedules and needs, and strengthening systems to track clients for follow-up. Sustainability also depends on having an adequate number of trained providers and reducing staff turnover. Although some challenges were found across all sites, others varied from country to country, suggesting that careful assessments before beginning new secondary prevention programs will optimize the probability of success.

Published: November 2013

AbstractCoal seams are dual porosity media containing two systems of fractures and matrix pores. The size of matrix pores is very small while specific surface area is large; a large amount of natural gas is adsorbed on the pore surface. It is generally believed that after the adsorbed gas desorbs, the desorbed gas in matrix pores first diffuses into cleats (fractures) under the driving of concentration difference, and then flows to the wellbore in the form of gas-water tow-phase flow. However, it is found that, predicted gas production based on the diffusion mechanisms of desorbed gas through matrix pores greatly deviate the actual production data. Through the preliminary research it is found that the diffusion theory ignores the existence of water in matrix pores, which makes the diffusion model inapplicable, and the gas production model based on the molecular diffusion has some problems.Therefore, we start our study on the initial distribution of gas and water in matrix pores, and then construct a more accurate transport model by studying the dynamics and phase characteristic of gas in water bearing matrix pores. Based on the transport model, a corresponding gas production prediction model is established, and the gas production rule of coal seam gas (CSG) is obtained.Results show that almost all desorbed gas in water bearing matrix pores linearly flows into cleats, the gas production rate can stabilize for a long time at the constant bottom hole flowing pressure condition. Through the application of gas production prediction model into the field gas wells, the predicted gas and water production by model are in good agreement with actual production data.Our study will provide a more accurate technique for gas production forecasting of CSG wells, and moreover, it will provide scientific evidence to the rational development of CSG reservoirs.
Improvement in smile esthetics following orthodontic treatment: A retrospective study utilizing standardized smile analysis
Authors: Maganzini Anthony L. , Schroetter Sarah B. , Freeman Kathy 
Published: November 2013

ABSTRACTObjective:To quantify smile esthetics following orthodontic treatment and determine whether these changes are correlated to the severity of the initial malocclusion.Materials and Methods:A standardized smile mesh analysis that evaluated nine lip-tooth characteristics was applied to two groups of successfully treated patients: group 1 (initial American Board of Orthodontics Discrepancy Index [DI] score &lt;20) and group 2 (initial DI score &gt;20). T-tests were used to detect significant differences between the low-DI and high-DI groups for baseline pretreatment measurements, baseline posttreatment measurements, and changes from pre- to posttreatment. A Spearman correlation test compared the initial DI values with the changes in the nine smile measurements.Results:Five of the smile measurements were improved in both groups following orthodontic treatment. Both groups demonstrated improved incisor exposure, an improved gingival smile line, an increase in smile width, a decreased buccal corridor space, and an improvement in smile consonance. Spearman correlation tests showed that initial DI value was not correlated to changes in any of the individual smile measurements.Conclusions:Smile esthetics is improved by orthodontic treatment regardless of the initial severity of the malocclusion. In other words, patients with more complex orthodontic issues and their counterparts with minor malocclusions benefitted equally from treatment in terms of their smile esthetics.

Published: November 2013

Abstract The paper deals with the process of shaping the operational effectiveness of military aircraft under some specific circumstances, i.e. while flying on missions. The term ‘effectiveness’ has been assumed to mean the probability of accomplishing an air mission by one of the aeronautical system’s components, i.e. the aircraft together with its pilot. There is a chance to improve the effectiveness, or make it worse, in subsequent flights, depending on how the maintenance support function. The correct operation and maintenance of the system’s components should provide that the following condition is satisfied: * Pk ≥ P , where Pk - effectiveness in the k-th flight, and P* - the lower demanded limit of effectiveness. The Authors drew their inspiration for this paper from publication [2].
Output Voltage Pulsation as Source of Diagnostic Information About Commutator-Type DC Generators
Authors: Gębura Andrzej , Radoń Tomasz 
Published: November 2013

Abstract The paper deals with operational issues related to DC generators of commutator types. Specific aspects of commutation are discussed in details as well as the effect of physical phenomena onto formation of the constant component in the pulsation waveform of the output voltage supplied by DC generators. The component of pulsation is the result of many physical phenomena and, according to knowledge sourced from the related literature, is split into several components. Each of these components is discussed in systematic way on the basis of theoretical background provided by referenced textbooks and papers and then verified by comparison against results of own research studies carried out in the ITWL laboratory. Particular attention is paid to effects associated with the commutation process, with consideration of symptoms related to failures, possibilities of their detection and prevention. Some other effects associated with variation in the nature of pulsation are discussed as well when defects such as shorts or breaks occur in the generator armature or stator. It has been demonstrated that those components of DC generators can be diagnosed by analysis of parameters in pulsation components.

Evaluation of Steering Disks in Mi-17 and Mi-24 Helicopters by Means of the Fam-C Method
Authors: Kurdelski Marcin , Gębura Andrzej 
Published: November 2013

Abstract The paper deals with selected issues related to operation of steering disks designed for helicopters that are currently in operation of the Air Force of the Republic of Poland. The attempt is made to present a prediction of hazards to the transmission gear of that helicopter where the forecast is based on a theoretical analysis of mechanical phenomena as well as the statistical and diagnostic analyses. The major attention is paid to the opportunity to diagnose hazardous locations of the helicopter steering disk with use of a non-destructive FAM-C method originally developed by ITWL. The method is based on tracking of frequency modulation parameters generated by the on-board AC generator. The examination does not require the installation of any additional sensor since the transmission is subjected to neither additional load nor distortions of the rotation speed occur. The authors of this study disclosed the initial results from diagnostic measurements as well as snapshots taken during the disassembling of steering disks from Mi-24 and Mi-17 helicopters that were operated under heavy duty conditions of military missions in Iraq and Afghanistan. They also suggested an easy and cheap method for field checking of the steering disk bearing by photogrammetric measurements. It is also demonstrated that the method of diagnostic investigations can be also spread onto other helicopter makes and types.
Investigation of the Oxidizer Charge Impact Onto Energetic Characteristics Demonstrated by the Stream of Gunpowder Gas Ejected by Solid-Propellant Missile Engines
Authors: Pietraszek Mariusz , Klemba Tomasz 
Published: November 2013

Abstract The study discloses outputs from examinations devoted to charges of oxidizers and their impact on behaviour of missile engine operation with particular attention to measures that are undertaken to counteract stall of a helicopter engine. Homogenous solid propellant for missile engines exhibits a negative oxygen balance. When a series of rocket missiles driven by means of such fuel is launched from the helicopter board there is a hazard of the engine stall effect that may lead to killing its engines. Admixture of potassium (II) sulphate (VI) that is added into the combustion chamber of a missile engine as an inhibitor of the combustion reaction favourably alters characteristics of the engine output power and, at the same time, is irrelevant to the available thrust of the engine. Application of the oxidizer as an insert into the engine substantially improves flight safety when rocket missiles are launched from an aircraft and makes it possible to avoid significant changes in the engine design. The paper outlines the results from investigations when a charge of K2SO4 was introduced into the Mk66 missile engine as a compressed bar and the working parameters of the engine were measured. The investigations on a vertical workbench comprised measurements of the engine thrust and temperature in the stream of exhaust gases. The measurement results were compared against figures sourced from the original data sheets of engines
Combustion of Coal-Mule Briquettes / Spalanie Brykietów Z Mułu Węglowego
Authors: Kijo-Kleczkowska Agnieszka 
Published: November 2013

Abstract
Combustion technologies coal-mule fuels create a number of new possibilities for organising combustion processes so that they fulfil contemporary requirements (e.g., in terms of the environment protection- related issues). The paper describes the problems of coal-mule fuel combustion that have acquired a wider significance as the quality requirements of coal combustion in power plants have been growing. Coal mines that want to fulfill expectations of power industry workers have been forced to develop and modernize plants of coal wet cleaning. It all results in the growing amount of waste arising in the process of coal wet cleaning which contains smaller and smaller coal undersizes. In this situation the concept of direct combustion of the above mentioned waste and their co-combustion with other fuels, coal and biomass, seems to be attractive. Biomass is one from the most promising sources of renewable energy. The main aim of the paper is to identify the mechanism and kinetics of combustion of coal-mule fuels and their co- -combustion with coal and biomass in the briquettes form based on extensive experimental research in air.

Abstract
Characterization and determination of liberation degree are the first stages of ore dressing. Block 4 of Jalal Abad mine, Kerman province, Iran, has three kinds of iron ores; D1, D2 and D3, with different grades. In this research, chemical analysis, mineralogy, liberation degree and magnetic enrichment studies were done by XRF, XRD, microscopic sections and Davis tube, respectively. The results indicated that D1, D2 and D3 had average iron grades of 58, 52 and 38%, respectively. The minerals of Magnetite, Hematite, Dolomite, Calcite and Quartz were distinguished. Average liberation degree was estimated about 500 μm by Microscopic studies. The results of magnetic tests showed that iron grade of D1, D2 and D3 concentrates increased to 70.46, 63.98 and 45.37%, respectively. The optimization of blending was investigated for production of accumulated concentrate with desirable iron grade (68%) using MATLAB software.

Abstract
Flotation tailings dumps represent a potential threat to the environment. To corroborate this, numerous environmental disasters have occurred worldwide in the past. Pollution caused by breaking of tailings dump dams and overflowing of hazardous materials is still present, after several decades, and continue to threaten the environment.
This paper presents a method for determining the most appropriate location for the flotation tailings dump using rough set theory. The review of the criteria that influence the choice of flotation tailings dump location is given. Based on these criteria, an analysis and evaluation of the proposed locations for the flotation tailings dump are done using rough set theory and the most suitable location that meets all the requirements is suggested.

Abstract
Our study on the venous vasculature of the kidney (the location and the formation of the renal veins) was performed on a total of 148 cases, using as working methods the dissection, the injection of contrast medium followed by radiography and the plastic injection followed by corrosion. Not all anatomical landmarks could be studied in all cases, each anatomical landmark being assessed on a number of different cases. The left renal vein formation was studied on 124 cases and we have found that the left renal vein may appear inside the renal sinus (intrarenal or intrasinusal) in 13.71 % of cases; in 17.74 % of the cases the confluence of the tributaries of the renal was at the medial border of the kidney, so juxtarenal and the most common form was the extrarenal vein (68.55 % of cases). The level of appearance of the right renal vein was studied on 122 cases, describing the following patterns: intrasinusal in 19.67 % of cases, juxtarenal in 27.87 % of cases and extrarenal in 52.46 % of cases.
The formation of renal veins was studied on a number of 114 cases, finding the following variations: in 56.14 % of the cases the renal vein formed from two venous trunks, in 38.60 % of cases from three venous trunks and in 5.26 % of cases from four venous trunks; we did not found cases of renal vein formed from more than 4 tributaries.

Abstract
Introduction: Intestinal parasitism represents an important problem of children health. Infestations with protozoa and helmints even have an increased incidence in children they weren’t observed because they were asymptomatic and atypical but with negative influence on their health regardless their immune status.
Objective: To evaluate parasitic infections in a collectivity of 38 children HIV+ from Cernavoda city (Hospis “St. Laurence”) over a period of 10 years (2002 - 2012).
Material and method: We performed two coproparasitologic examinations (in year 2002 - before antiretroviral treatment and in year 2012 - after 10 years of antiretroviral treatment) by concentration and staining methods and ELISA for Cryptosporidium parvum antigen.
Results: In our group of study the median age was 11.65 yrs. in 2002 and 20.6 yrs. in 2012. Sex ratio was M: F = 1:1.2. In year 2002 we found an incidence of parasitic disease of 94.9%, and in year 2012 we found an incidence of 26.31%. In year 2002 we found 6 cases of Giardia intestinalis, 5 cases of Blastocystis hominis, 15 cases of Chilomastix mesnili, 2 cases of Entamoeba coli, 1 case of Ascaris lumbricoides, 2 cases of Hymenolepis nana and 5 cases of poliparasitic disease. In year 2012 we found 4 cases of Giardia intestinalis, 2 cases of Entamoeba coli, 2 cases of Blastocystis hominis and one case of Isospora belli and another one case of Ascaris lumbricoides.
Conclusions: After ten years of HAART the incidence of parasitic diseases registered an important decrease from 94.9% to 26.31%.
