The role and mode of action of UVC hormesis in reducing cellular oxidative stress and the consequential chilling injury of banana fruit peel

The reduction of cellular oxidative stress causing chilling injury (CI) of banana fruit peel by UV-C hormesis was investigated. Banana [Musa (AAA group, Cavendish subgroup) cv. Cavendish] fruits were treated with UV-C at dosages of 0.02 kJ m-2, 0.03 kJ m-2 or 0.04 kJ m-2 prior to storage at 5 and 25°C. Symptoms of CI were observed when fruits stored at 5°C and severity was increased with time of storage. However, UV-C treatment reduced both the incidence of CI and its severity compared with controls. UV-C treatment activated phenylalanine ammonia-lyase and resulted in higher levels of total phenolic compounds in comparison with untreated controls. Our results showed that oxidative stress caused by CI in banana resulted from the accumulation of reactive oxygen species (ROS) intermediates such as H2O2 and superoxide anion, and at CI-inducing temperatures, a marked increased in H2O2 content was observed. However, UV-C treatment led to significantly higher activities of superoxide dismutase, catalase, peroxidase, ascorbate peroxidase, and glutathione reductase compared to control fruit during later storage. The activation of antioxidants by UV-C treatment reduced cellular oxidative stress damage, as indicated by lower levels of malondialdehyde and DNA degradation. In addition, heat-shock protein (HSP) 70 gene expression was increased by UV-C treatment, suggesting a possible mode of action of UV-C in the prevention of cellular damage and maintenance of cellular homeostasis. Taken together, these results suggest that the development of CI symptoms in banana fruit are associated with ROS accumulation, and UV-C treatment, by activation of defense mechanisms such as antioxidant enzymes and HSP70 gene expression, can reduce cellular oxidative stress, thus preventing membrane degradation and DNA damage associated with CI.
Implementation Of GSM Based Irrigation Systems In Nigeria

Apart from oil, agriculture is Nigeria’s second backbone and irrigation is called the lifeline. Irrigation is the method of synthetically providing water to land where crops are cultivated. Prior to the inconsistent atmospheric conditions which vary from place to place in large farm lands, it became very tedious to uniformly and manually irrigate a large farm land at the same time. To meet the demand, a new type of system is needed to regulate the irrigation. Automatic irrigation is a form of irrigation system that incorporates the theory of digital control and feedback system with irrigation. In this system of irrigation, critical information (soil moisture content, humidity, sunlight) is sent to a microcontroller which is provided by sensors which is used by the microcontroller to schedule irrigation by turning on or off a water pump that supplies water to the farmland. The proposed system implemented GSM is used to report the detailed about
THE INFLUENCE OF CAMERA CALIBRATION PARAMETERS ON 3D BUILDINGS MODELS CREATION

In recent years 3D buildings models, have known a great evolution, being used in many scientific domains of activity. For many years, close-range photogrammetry has been dealing with the extraction of high accuracy informations from images. The used techniques, mostly require a very precise calibration of metric and non-metric digital cameras. This article presents the importance of a good determination of the intrinsic parameters in obtaining a high quality and accurate 3D models of buildings. In order to obtain the results, the 3D model of the historical monument “Dosoftey House” from IaşiCity area was created, using images acquired with the Nikon Coolpix L810 digital camera and the intrinsic parameters determined, using both, a 2D calibration grid and a 3D calibration target. The 3D building models created based on this two sets of parameters, were evaluated based on precise measurements made with a total station.
Data Encryption using Advanced Encryption Standard with Key Generation by Elliptic Curve Diffie-Hellman

In today’s era ubiquitous computing is worldwide adopted. Internet is the main root for providing a ubiquitous network for communication between different people across the world, such communications can be through a wireless channel or wired channel that helps in getting messages or confidential information exchanged between different groups of people. Data security is of utmost importance because of wireless communications on insecure network. So the concept of cryptography is emerged which is nothing but known as an art of writing a secret code and it provide diverse set of services for protecting data over network such as authentication, confidentiality, non-repudiation and integrity. Cryptography offers wide range of algorithms which can help to guard communications over an insecure network such as symmetric encryption techniques which uses one key for encryption and decryption. For a symmetric cipher security can be compromised as it uses a single key, with this an advantage comes out while using an asymmetric security technique that makes use of a pair of keys to secure communications over unsafe channels. In this paper the positive characteristics of both the techniques discussed above are taken and a hybrid approach is used to guard messages on timid wireless medium. AES which is known as symmetric algorithm is combined with ECDH algorithm that is asymmetric by nature and is an amalgam of ECC and Diffie-Hellman – anonymous key agreement protocol. Different text files are taken as input to the model with varying sizes. Encryption and decryption is performed using Advance encryption standard (AES) whereas ECDH will help in securing the communication for a session set up between client and server by generating key for AES. Also Diffie-Hellman will provide security by establishing a shared secret between client and server after successful key agreement. At last analysis of proposed model is done on the basis of different metrics like storage, encryption time, decryption time, correlation and avalanche effect. Proposed approach has been proven effective in reducing the gaps discovered in the present literature.
Noncontact Vibrometer Based on the Fibre Optical

Research results of designing a vibrometer based on the state-of-the-art circuitry are presented. An interferometric scheme sensitive to the distance to an object based on the Michelson interferometer is used. A quadrature interferometric signal is received by laser pumping current modulation and further signal filtering. Object surface displacement signals as a result of experimental measurements and processing of the data obtained signals of an object’s surface displacement are recovered for the vibration mode with the preset frequency and amplitude. The surface vibration frequency corresponds to the generator signal frequency (30 Hz), with the amplitude of the investigated point being equal to 4 ± 0.05 μm. A random displacement amplitude equals 0.3 μm when signal is absent. It is revealed that the vibrometer setup can detect quadrature interferometric signals and recover surface displacements of vibration objects. Further research on the proposed setup as well as on improving its accuracy characteristics and bringing it to a prototype are planned.
Study of the influence of modified (non-)strange baryon and meson spectra on hadron densities calculated within the statistical hadronization model

The statistical hadronization model describes the yields of hadrons produced in heavy-ion collisions. It successfully calculates and predicts particle yields in a wide range of collision energies. However, thermal fits to LHC data showed a deviation of the proton yields of nearly 3σ. These deviations are known as the proton anomaly. An earlier study showed that the inclusion of non-strange baryon states in the model enlarged the deviations for the proton yields significantly. It was suggested that this could be due to an imbalance in the implemented hadron spectra. The influence of the implementation of a more complete set of hadrons into the statistical model is studied in this work. It is shown that the further extension does not reduce the deviations coming from the insertion of non-strange baryon states significantly. Finally, a correction that makes use of the S-matrix formalism and has which been able to improve the proton anomaly, has been applied to the calculations with the modified spectrum. It turns out that this correction is not able to explain the large deviations and an alternative explanation is presented.

In this paper, image compression technique is presented based on the Zonal transform method. The DCT, Walsh, and Hadamard transform techniques are also implements. These different transforms are applied on SAR images using Different block size. The effects of implementing these different transforms are investigated. The main shortcoming associated with this radar imagery system is the presence of the speckle noise, which affected the compression results.
Humor as a Defense Mechanism and Working Instrument of the Cognitive-Behavioral Therapy

The present theoretical paper sustains the idea that humor represents a complex phenomenon, characterized by a series of multidimensional valences whose implications can be observed at multiple levels of human functioning, by briefly looking over and analyzing its various conceptualizations, while still following two main objectives: on one hand to define and understand from a psychoanalytic point of view, the role of humor as a defense mechanism in people’s lives, and on the other hand to describe humor as a tool in the therapeutic work framed by the cognitive-behavioral approach. Thus, among other relevant aspects, we discuss the distinction that Freud proposed in 1905 concerning the witticism, comic and humor, as well as the complexity of their intrapsychological relationships; we dissect the components of humor and their complex functioning underlying the psychoanalytic defense processes; we present and comment the cognitive theories of humor, as well as the evolutionary perspective regarding the utility of humor in human communication; and we analyze humor as an essential part of nowadays psychotherapeutic interventions. Moreover, we highlight the necessity of conducting more scientific validated studies that ask the beneficial effects of humor in cognitive-behavioral therapy.
Developing offshore outsourcing practices in a global selective outsourcing environment – the IT supplier’s viewpoint

Currently, internal IT organizations use outsourcing and offshore arrangements to achieve cost savings and gain access to new capabilities. It was found that suppliers’ personnel at the operational level can face challenges with internalizing their operations based on the agreed outsourcing practices and transferred responsibilities. This study gives voice to the supplier and studies the impact of offshore outsourcing operation development activities. The internal IT unit from Nokia Devices selectively outsourced global IT service activities and responsibilities to the IT supplier. The outsourced activities were implemented by offshore centers in India and China. It was found that the global selective outsourcing environment (GSOE) did not provide a solution to all of their expectations, and new unexpected challenges occurred. Several practices, communication and information sharing, and behavior-related lessons learned items were identified. It was found that the GSOE operation needs to be developed and implemented in an agile and incremental manner, instead of a singular implementation approach. Also, the globally distributed teams’ group dynamics critically impacted on the teams’ ability to work. The lessons learned items and recommendations can be utilized by other companies during their mode-of-operation development.
Status and technology in the professionalisation of translators. Market disorder and the return of hierarchy

The professional status of a translator is traditionally indicated by a set of social signals including previous experience, academic qualifications, professional accreditation and membership of associations. When those signals shifted from print and word-of-mouth to electronic media, some degree of market disorder resulted with respect to globalization of translator-client contacts, the growth of volunteer translation, access to free online machine translation, and the corresponding motivation to steal the identities of professional translators. Three case studies of websites and forums that have been associated with market disorder (ProZ.com, a comparison of aRGENTeaM and GrupoTS, and the Translator Scammers Directory) indicate that the initial disorder has been challenged and in some cases significantly corrected, with new forms of signalling appearing within the electronic environments. ProZ.com has instigated its own accreditation system, the volunteer subtitling communities have developed elaborate internal hierarchies of control, and the stealing of translators’ identities has been challenged through more sophisticated use of the same electronic media that allowed the thefts. In the new configuration of signals, however, it would seem that academic qualifications have less market value than does verifiable professional experience, while professional accreditation still has value but can be forged. For many segments of the translation market, the return to market equilibrium will require greater attention to new signalling mechanisms, with more sophisticated uses of electronic communication.
Thermal Analysis of the Silicon Pixel Detector for the Mu 3 e Experiment

The Mu3e experiment will search for the charged lepton flavour violating decay μ → e+e−e− with a target sensitivity of one in 10 decays. To reach this sensitivity the Mu3e detector is based on a combination of a silicon pixel tracking system, a scintillating fibre detector and a scintillating tile detector. The pixel detector and the scintillating fibre detector are optimized and thinned in order to minimize the effects of multiple Coulomb scattering. Cooling the tracking detector with gaseous helium has been chosen as it offers a reasonable compromise between radiation length and cooling potential. In the context of this thesis, the performance of the helium cooling system was studied using Computational Fluid Dynamics simulations. The analytical results indicate that an optimized design is capable of keeping the temperatures below 70 ◦C for a given heat load of 250–400 mW/cm. Furthermore, heatable modules for a thermal-mechanical mock-up of the detector were characterized. In combination with the simulations the results from the thermal-mechanical mock-up can be used to predict the deformation of the detector due to temperature changes and pressure gradients.
TWO-PHASE FLOW PATTERNS DURING AIR-WATER UPWARD FLOW ACROSS TUBE BUNDLE

This paper presents flow pattern experimental results for upward flow of air-water mixtures across a triangular tube bundle with 19 mm OD tubes and 24 mm transversal pitch. Experimental conditions covered water superficial velocities ranging between 0.020 and 1.500 m/s, and air superficial velocities between 0.20 and 10.00 m/s. Flow patterns were identified subjectively, based on visual observations through side windows, helped by images and videos captured with a digital camera, and objectively based on the analyses of the signal of a differential pressure transducer, adopting the k-means clustering method. Experimental results are compared with predictive methods available in the literature.
Machine Vibration induced Underwater Acoustic Radiation

A coupled FEM/BEM for solving fluid-structure interaction problem in structure-borne noise propagation and underwater acoustic radiation is present in this paper. In order to improve the habitability and stealth low noise condition is required in various types of ships. One of the dominant components is the radiated airborne and underwater noise caused by ship hull vibration. Accordingly, the estimation of structure-borne sound characteristics of a ship is important in the design of a quieter ship-structure. The hull vibration response and pressure distribution on the wetted surface of a ship subjected to excitation sources can be analyzed by utilizing the developed method. Further discussions on the evaluation of surface complex power, radiation and reactance power have been conducted. Two cases were studied, a submerged spherical shell subjected to a uniformly harmonic pressure excitation and a scale model of engine room structure subjected to machine excitations, to illustrate the applications of the analytical model. The surface pressure, the normal velocity on the wetted surface, the surface complex power, the radiation power, the reactance power, the vibrational displacement and the radiated underwater sound pattern have been computed. Comparison of the predicted results and that by measurement indicates that the numerical model is creditable. In addition, the effect on underwater acoustic radiation at the elastic mounts for the engine is discussed.
CFD Analysis of Wind Turbine Airfoil at Various Angles of Attack

The main aim of the study was to analyze the NACA0012 wind turbine airfoil at various angles of attack, keeping the Reynolds number constant. The efficiency of the aerodynamic wind turbine is greatly influenced by the aerodynamic efficiency of the airfoil. In the present study NACA0012 airfoil is considered as a suitable wind turbine blade. The geometry and analysis was done using Ansys-Fluent. Calculations were done for constant air velocity altering only the angle of attack. For the computational domain an unstructured mesh with sphere of influence and inflation was selected, taking care of the refinement of the grid near the airfoil in order to enclose the boundary layer approach. The CFD simulation results show close agreement with the results obtained from wind tunnel testing experiments, thus suggesting CFD analysis as a reliable alternative to experimental methods.
THE MIX EVALUATION DATASET

Research on perception of music production practices is mainly concerned with the emulation of sound engineering tasks through lab-based experiments and custom software, sometimes with unskilled subjects. This can improve the level of control, but the validity, transferability, and relevance of the results may suffer from this artificial context. This paper presents a dataset consisting of mixes gathered in a real-life, ecologically valid setting, and perceptual evaluation thereof, which can be used to expand knowledge on the mixing process. With 180 mixes including parameter settings, close to 5000 preference ratings and free-form descriptions, and a diverse range of contributors from five different countries, the data offers many opportunities for music production analysis, some of which are explored here. In particular, more experienced subjects were found to be more negative and more specific in their assessments of mixes, and to increasingly agree with each other.
Appendix to “ Numerical simulations of boundary-layer bypass transition due to high-amplitude free-stream turbulence ”

In figure 20 we show the evolution of the FST integral length scale L33 computed by integrating the spanwise autocorrelation function of the spanwise velocity component. In the figure we also compare our data to power law fits of the form y = C (x − x0) 1/2 (Roach 1987), assuming that L33 is an adequate approximation to L11. It can be seen that in both cases SLS and T3B, L33 grows more slowly than the corresponding power law. One possible explanation is that the finite size of the computational domain prevents natural growth of free-stream eddies.
Evaluation of Patient Satisfaction in Relation to Patient Factors in Surgical Centre-A Study from Central India

Background: Patient satisfaction is influenced by patient factors and service-provider factors. The cultural, social and economic conditions of the people living in the region affect the perceptions, attitude, and understandings of the persons, which has a bearing on the satisfaction they derive from the hospitals and its services. The study aims to find the relationship between patient satisfactions focusing on the patient’s sociodemographic characteristics. Methods: This is a cross-sectional study, which was conducted from 1 July, 2012 to 15 August, 2012 among the patients admitted to a private surgical hospital in Bhopal, India. A structured, validated questionnaire form was distributed using simple randomization method. The patients themselves or their representative filled up the questionnaire. Data was analyzed and appropriate statistical tests applied. Results: Seventy five patients with mean age of 49.53 ±20.2 years were analyzed. Patient's age (p<0.05), inhabitant (p<0.01), educational attainment (p<0.02) and income level (p<0.02) had a significant relationship with patient satisfaction level. The patient’s gender (p<0.50) did not had a significant relationship with patient satisfaction level. Conclusion: Patient's age, inhabitant, educational and income level are related to their satisfaction levels. We further suggests about optimizing patient-service provider communication by identifying potential age groups to target with improvement efforts, leading to enhancement of patient satisfaction.

Investigating digital storytelling method in German as a foreign language teaching

It is obvious that current students are interested in digital technology. As a result, it is inevitable not to make use of instructional technologies. Web 2.0 tools, one of which is digital storytelling tool, hold an important place in education. One can create his/ her own story and narrate it digitally. Thus, digital storytelling is considered a recent student-centered learning method. There seems to be a scarcity of research both in Turkey and the world on German language education and digital technology. This case study investigated the digital storytelling method in an Anatolian High School in southeast part of Turkey. With 97 student participants, this study results revealed that digital storytelling method increased student motivation and enhanced language and computer skills. This study showed that digital storytelling method can easily be applied in Turkish context and it promotes foreign language education. Based on the study results, pedagogical implications and suggestions were provided for teachers, teacher trainers, and researchers.
NASA / CRm 1998-206608 Propulsion Options for Primary Thrust and Attitude Control of Microspacecraft

Order of magnitude decreases in the size of scientific satellites and spacecraft could provide concurrent decreases in mission costs because of lower launch and fabrication costs. Although many subsystems are amenable to dramatic size reductions, miniaturization of the propulsion subsystems is not straightforward. There are a range of requirements for both primary and attitude control propulsion, dictated by mission requirements, satellite size, and power restrictions. Many of the established propulsion technologies can not currently be applied to microspacecraft. Because of this, micro-electromechanical systems (MEMS) fabrication technology is being explored as a path for miniaturization.
