Milk and dairy products as a possible source of environmental transmission of Helicobacter pylori

Helicobacter pylori (H. pylori) is found worldwide, and it is estimated that more than 50% of the population is infected. The presence of H. pylori in the gastrointestinal tract is associated with the occurrence of serious human diseases such as chronic gastritis, duodenal ulcer or gastric cancer. Therefore, the International Agency for Research on Cancer classified H. pylori as a Group 1 carcinogen in 1994. The routes of H. pylori transmission are not yet precisely known. Many authors agree that humans may become infected by H. pylori through foodstuffs. Milk is one of the basic foods of people of all age categories. Helicobacter pylori has been isolated from milk derived from various livestock, such as cows, sheep, goat, camel or buffalo milk. This review research paper indicates that H. pylori may be present in different types of foods and suggests that consumption of milk and selected dairy products may be a source of H. pylori infection for humans.
Using Sensor-based Demand Controlled Ventilation to Realize Energy Savings in Laboratories

Abstract : The building sector in the United States accounted for 41% of domestic and 7% of global energy consumption in 2010, with heating, ventilating, and air-conditioning (HVAC) activities consuming approximately 41.4% of the total facility energy consumption. Within the HVAC system, the parasitic energy accounts for one-third of the total energy consumed while heating and cooling accounts for the balance. The fan energy is approximately 85% of the total parasitic energy in the HVAC system. In a laboratory, energy related to ventilation can account for nearly half of the electrical energy demand. A carbon dioxide (CO2)-based demand controlled ventilation (DCV) strategy can reduce the ventilation requirement by monitoring the indoor air quality (IAQ) of a space and modulating the ventilation based on the real-time occupancy. This research presents a tool for laboratory managers to quickly determine if employing a DCV system is potentially life-cycle cost effective. The tool presented is not to be used as sole justification for implementing a DCV system; instead, laboratory managers using this tool will be able to quickly determine if further investigation into DCV installation is warranted. The results show that a DCV system is life-cycle cost effective for many different HVAC system total pressure and square footage combinations.
Enhanced electrical characterization of MEMS resonators using on-chip parasitic feedthrough self-cancellation

We report a technique for the self-cancellation of parasitic capacitive feedthrough in microresonators by employing an identical pair of resonators, one of which is excited while the other functions as a matched negating compensation capacitor. This on-chip self-compensation scheme results in an enhancement in the resonance peak height of a wine glass mode disk resonator by an additional 18.8 dB
iGPS capability study

This report presents the results of testing of the Metris iGPS system performed by the National Physical Laboratory (NPL) and the University of Bath (UoB), with the assistance of Metris, and Airbus at Airbus, Broughton in March 2008. The aim of the test was to determine the performance capability of the iGPS coordinate metrology system by comparison with a reference measurement system based on multilateration implemented using laser trackers. A network of reference points was created using SMR nests fixed to the ground and above ground level on various stands. The reference points were spread out within the measurement volume of approximately 10 m ´ 10 m ´ 2 m. The coordinates of each reference point were determined by the laser tracker survey using multilateration. The expanded uncertainty (k=2) in the relative position of these reference coordinates was estimated to be of the order of 10 µm in x, y and z. A comparison between the iGPS system and the reference system showed that for the test setup, the iGPS system was able to determine lengths up to 12 m with an uncertainty of 170 µm (k=2) and coordinates with an uncertainty of 120 µm in x and y and 190 µm in z (k=2).
Maintaining human agency in the design on context-aware systems: Design games in a dental surgery

This paper describes a series of design games, specifically aimed at exploring shifts in human agency in order to inform the design of context-aware applications. The games focused on understanding information handling issues in dental practice with participants from a university dental school playing an active role in the activities. Participatory design activities help participants to reveal potential implicit technical resources that can be presented explicitly in technologies in order to assist humans in managing their interactions with and amidst technical systems gracefully.
Impact of Soaking and Germination Time on Nutritional Composition and Antioxidant Activity of Nigella Sativa

Indian traditional dishes make use of Nigella sativa seeds because of its distinctive aroma and taste but its application is restricted due to its pungent flavour which can be overcome by various methods of processing such as roasting, soaking, germination etc. Soaking and germination has a positive impact on the nutritional, sensorial and phytochemical attributes of Nigella sativa. The current study was carried out to standardize the optimum soaking and germination conditions with improved nutritional, sensorial and phytochemical attributes of seeds. Nigella sativa seeds were soaked for different time duration (0 hr, 6 hr, 12 hr and 18 hr) followed bygermination for0, 7, 9 and 11 days. The soaked and germinated samples were exposed to a temperature of 50ºC for drying till the constant moisture was obtained and analysed for various physiochemical, nutritional and sensory attributes. All the attributes under study were significantly affected by soaking and germination as compared to the control. Comparatively, except the moisture content all the phytochemicals and nutritional attributes decreased significantly from the control sample. Based on the qualitative attributes, soaking done for 18 hours along with 9th day of germination was observed to be the best and can be considered as the optimum condition to maintain the phytochemical to the safe level as well as reducing the antinutritional factors which can further be used for value addition.
Soil cracking propagation due to dryness and its relation to suction

Investigation of Crack Intensity Factor is essential as it affects the mechanical and hydraulic behaviour of soils. Soil water coming from the wet seasons or from the water table, is removed by evaporation during the driest season. The loss of water provokes a significant increase in suction. When it exceeds the tensile strength of the soil, cracks occur that can modify the mechanical and mainly hydraulic properties of the soil, creating preferred paths for water infiltration. Little research is conducted on quantifying cracking in soil relating it to its hydraulic properties. This research aims to investigate the cracking of soils with focus on analysing its relation to water content and soil suction. Soils from a specific region in Brazil with clay predominance are collected and characterized. Unsaturated soil specimens are prepared and subjected to environmental real conditions in order to progressively check the consequences caused by the environment in soils with different clay content during four weeks. The Crack Intensity Factor is measured along the time through image processing. The water content is monitored through volume water content sensors. The measured results are evaluated to correlate crack intensity factor as function of weather variables and soil water content.
Problems With Kosher Slaughter

Ritual slaughter to produce kosher meat is rooted in the teachings and writings of the Talmud. However, the preslaughter handling features of modern systems, particularly the shackling and hoisting of large steers, contravene the basic message of humaneness included in the teachings. The throat-cutting of a live, conscious animal is relatively pain-free, provided that certain precautions are followed, but U.S. kosher plants need to install newly developed conveyor­ restrainer systems to eliminate the abuses of shackling and hoisting. Conveyor­ restrainer systems for large and small animals are discussed.
Electrostatics, Principles, Problems and Applications

Electrostatic effects have been known since ancient times but only with the discovery of the electron in the present century has an adequate theory started to develop to explain them. There is now renewed interest in the subject caused by the need to understand the electrostatic causes of explosions, and industrial applications such as electrostatic powder coating and photocopying. This book provides a comprehensive study of the cause and effects of charge accumulation in solids and liquids. The basic theory of electrostatics is presented at the beginning of the book and all the applications and problems which are subsequently described can be understood using this. For those readers who wish a higher-level treatment the final chapter is devoted to more advanced theory and covers, for example, solutions of Laplace's equation and Earnshaw's theorem. The bulk of the book covers the applications of electrostatics. There is a treatment of the electrification of solids and liquids, including corona and induction charging, followed by a chapter on measurement and instrumentation. There are many industrial applications of electrostatic effects, for example in pollution control and metal finishing, and these areas are covered comprehensively. On the other hand, electrostatics can be a problem causing, for example, excessive wear due to electrostatic adhesive forces. These areas are also fully discussed. Extensive references are given, to enable readers who wish to study one particular aspect in greater depth to pursue the subject further. Little calculus is used so that this book will be readily understood by engineers and scientists of any discipline. As such, it is an accessible, as well as a comprehensive, source of reference to everyone concerned with electrostatics.
Feasibility of total system for ground protection – power generation - construction waste material reusing

In order to maintain the current standard of living without deteriorating the global environment, it is necessary to develop and spread the effective power generation methods using clean energy. Rational ground reinforcement is necessary to minimize the ground damage caused by frequent natural disasters such as earthquakes. It is important to actively reuse the construction waste material for reducing the economic cost of civil works. In this study, one of the useful tools for constructing and maintaining a recycling-oriented society is considered. First, a concept of the total system to perform both ground reinforcement and electric power generation using the recycled asphalt pavement material and newly prepared T-shaped unit is proposed. The T-shaped unit that is referred as a PG unit in this study mounts the electric circuit with Peltier device. A series of the field monitoring for electric power generation and the laboratory test for the mechanical properties of protected ground are conducted for discussing the feasibility of the proposed total system. The results of the field monitoring show that the newly prepared PG unit can generate the electric power by using the temperature on the ground surface. In the laboratory test, it is also confirmed that the bearing capacity of the ground can be improved by using recycled asphalt pavement material and PG unit waste. The both results of field monitoring and laboratory test imply that the proposed total system can be realized.

Tool for Quantitative Risk Analysis of Urban Flooding

One of the effects of climate change is an increasing frequency of heavy rainfall events, which in turn leads to increased flooding damage in urban areas. The purpose of this study was to develop a tool for dynamic risk evaluation that can be used to fulfil several of the goals in the European Flood Risk Management Directive. Flood risk analysis was performed as a spatial GIS analysis with the FME software. The primary data source for the analysis was a 1D/2D model calculation, wherein 1D models described the pipeline network and the watercourses and a 2D model described surface runoff. An ArcGIS online platform was developed to visualize the results in a format understandable for decision makers. The method and tool were tested for the Norwegian capital of Oslo. The tool developed in the study enabled the efficient analysis of consequences for various precipitation scenarios. Results could be used to identify the areas most vulnerable to flooding and prioritize areas in which measures need to be implemented. The study showed that for urban areas in steep terrain, it is essential to include water velocity and depth-integrated velocity in risk analysis in addition to water depths and pipe network capacity.
Mediating cultural values in a multimedia installation

This paper sets out approaches and trends in interactive and smart solutions designed to foster and promote cultural heritage through a multimedia educational approach. The research presented aims at envisioning novel strategies to facilitate learning by encouraging visitors to interact directly and physically with the heritage on display, and to communicate cultural messages. Analysing the interactions between the user and different media and their narrative potentialities, we describe an installation which allows visitors to meet a life-sized simulated hologram and interact with it. The project is set in the field of Human Computing Interaction (HCI), looking at the world of digital encounters and interactive systems based on embodied interaction, investigating if and how the designers, as a mediator between different media and tools, succeeded in achieving their aims and proving the envisioned user experience. Relying on user tests and direct observation, we discuss how the interactive exhibit and the digital character affected visitors’ behaviour, effectively capturing their attention and fostering interaction. Furthermore, we examine how visitors perceived the digital character and the gestures they asked them to perform, directly or indirectly, to trigger actions. In conclusion we generalize the results in terms of possible translations for teaching design basics in higher education.
A Study on the Commercial Aircraft Pilot's Go -around Decision Making

This research examined the influence of status and regulatory focus on go-around decision making. The result showed that there was no difference between captains and first offers on the go-around decision making about various landing situations. But there was significant relationships between regulatory focus and go-around decision making. Prevention focus was positively related with uncertain situation, and runway situation. Promotion focus has positive relationship with deficiency situation but has negartive relationship with runway situation.
The Influence of Ship Deck-Edge Lighting on Perception of Position and Movement During Helicopter Recovery

Abstract : Accurate perception of position and self-movement is a critical factor for many tasks in aviation; particularly low-level flight, take off and landing. An especially demanding task of this kind is that of deck landings for rotary-wing aircraft, which are often conducted during the night. During night operations, ship-based lighting is used to assist the aircrew and flight-deck staff in the conduct of take-off and landing. While reasonably effective, the lighting systems currently employed by the Royal Australian Navy (RAN) were not designed specifically with the aim of enhancing aircrew visual perception. In two experiments a deck-edge light (DEL) system which provides a richer visual cueing environment for the aircrew than traditional point-source lighting systems was investigated in terms of its potential benefits for aircrew visual perception. These experiments could reveal no clear performance advantage for DELs over standard point-source lights. In both experiments, participants were asked to make ratings of their confidence in their judgments. Only a very weak relationship was found between accuracy and confidence, suggesting that care should be exercised when subjective ratings are interpreted in place of performance data. Further investigation is required in order to understand the potential of DEL systems for enhancing the safety of night operations.
Seltene Erkrankungen der Nase, der Nasennebenhöhlen und der
 vorderen Schädelbasis

Seltene Erkrankungen der Nase, der Nasennebenhöhlen und der vorderen Schädelbasis stellen aufgrund der niedrigen Inzidenz und den daraus resultierend eingeschränkten diagnostischen Kriterien sowie therapeutischen Optionen eine Herausforderung dar. Der Schwellenwert, ab dem eine Erkrankung als selten zu werten ist, liegt bei höchstens 5 Betroffenen pro 10 000 Personen. Innerhalb dieser Erkrankungen gibt es allerdings extreme Schwankungen. So gehören einige seltene Erkrankungen, wie z.B. das invertierte Papillom, zu den regelmäßig diagnostizierten und therapierten Krankheitsbildern einer größeren Klinik für Hals-Nasen-Ohrenheilkunde. Andererseits liegen bei anderen seltenen Erkrankungen und Fehlbildungen weltweit deutlich unter 100 Fallberichte vor, was die Notwendigkeit einer Bündelung der verfügbaren Erfahrung zu Diagnostik und Therapie unterstreicht.Die vorliegende Arbeit gibt eine Übersicht zu seltenen Erkrankungen der Nase, der Nasennebenhöhlen und der vorderen Schädelbasis aus den übergeordneten Bereichen Erkrankungen / Syndrome des olfaktorischen Systems, Fehlbildungen der Nase und Nasennebenhöhlen, Belüftungs- und Funktionsstörungen sowie benigne und maligne Tumore. Die Einordnung sowie Angaben zu Diagnostik und Therapiemöglichkeiten wurden unter Berücksichtigung der aktuellen Literatur erstellt.
A Comparison of Pharmaceutical Prices for Generic Erectile Dysfunction and Benign Prostatic Hyperplasia Medication in 2 Socioeconomically Disparate New York City Neighborhoods

Abstract Introduction: Erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) are frequently managed with medications. Variability and poor understanding of medication prices have been shown to hinder patient adherence, leading to worse clinical outcomes. We sought to explore how pharmacy type and neighborhood socioeconomic status influence pricing for generic ED and BPH medications. Methods: A total of 96 pharmacies within the adjacent higher income Upper East Side (UES) and lower income East Harlem (EH) New York City neighborhoods were classified as chain or independent. Telephone surveys identified cash prices for 30-day supplies of 14 medications including phosphodiesterase 5-inhibitors, 5-alpha reductase inhibitors, alpha blockers and antispasmodics. Pricing variability based on pharmacy type and neighborhood was evaluated using Mann-Whitney U-tests. Results: Of 96 pharmacies, 81 responded (84.4%). Independent pharmacies showed significantly reduced prices for 9/14 and 14/14 medications in UES and EH, respectively. The greatest independent pharmacy price reductions were for tadalafil 20 mg (15.0-fold in UES, 26.7-fold in EH) and sildenafil (8.4-fold in UES, 15.4-fold in EH). The least significant reductions were in mirabegron (1.1-fold in UES, 1.2-fold in EH). Independent pharmacies in EH showed lower prices for 9/14 medications compared to those in UES. Conclusions: Across both neighborhoods, independent pharmacies offered consistently lower cash prices for ED and BPH medications. Lower independent pharmacy prices in the lower income EH neighborhood suggest that neighborhood socioeconomic status may impact pricing. Physicians and patients alike must understand the factors that influence pricing to ensure more optimal patient compliance for uninsured patients.

Adverse Childhood Experiences, Depression, Exposure to Suicide, Self-injury, Defeat, and Entrapment among Suicide Attempters and Non-suicidal People

Background: Suicide is an important concern with regard to mental health and needs more attention in Iran. Objectives: This study aimed to compare depression, exposure to suicide, self-injury, defeat, and entrapment, and adverse childhood experiences in suicide attempters and normal people. Materials and Methods: The current research method was descriptive in the form of ex post facto research. The research community included two groups of (1) suicide attempters, and (2) normal students. Research measures included the Patient Health Questionnaire-2, exposure to suicidal behavior, non-suicidal self-injury, short defeat and entrapment scale, adverse childhood experiences questionnaire, and future self-injury. The data were analyzed using t-test. Results: The results showed a significant difference between groups on the mean values of depression (2.27 for the non-suicidal group vs. 3.87 for the suicidal group), adverse childhood experiences (5.82 vs. 0.95), exposure to the attempted suicide (0.28 vs. 0.50), self-injury behavior (0.36 vs. 2.13), and future self-injury likelihood (0.56 vs. 2.13). The most significant differences belonged to the defeat and entrapment variable and adverse childhood experiences (P < 0.01). Conclusions: Thus, defeat and depression play an important role in predicting suicide, so we should intervene in these two states of mind.
