Published: July 2017

Here, we propose simple diamond functionalization by carboxyl termination for adenosine triphosphate (ATP) detection by an aptamer. The high-sensitivity label-free aptamer sensor for ATP detection was fabricated on nanocrystalline diamond (NCD). Carboxyl termination of the NCD surface by vacuum ultraviolet excimer laser and fluorine termination of the background region as a passivated layer were investigated by X-ray photoelectron spectroscopy. Single strand DNA (amide modification) was used as the supporting biomolecule to immobilize into the diamond surface via carboxyl termination and become a double strand with aptamer. ATP detection by aptamer was observed as a 66% fluorescence signal intensity decrease of the hybridization intensity signal. The sensor operation was also investigated by the field-effect characteristics. The shift of the drain current–drain voltage characteristics was used as the indicator for detection of ATP. From the field-effect characteristics, the shift of the drain current–drain voltage was observed in the negative direction. The negative charge direction shows that the aptamer is capable of detecting ATP. The ability of the sensor to detect ATP was investigated by fabricating a field-effect transistor on the modified NCD surface.

Published: July 2017

Microfluidics is quickly becoming a key technology in an expanding range of fields, such as medical sciences, biosensing, bioactuation, chemical synthesis, and more. This is helping its transformation from a promising R&D tool to commercially viable technology. Fuelling this expansion is the intensified focus on automation and enhanced functionality through integration of complex electrical control, mechanical properties, in situ sensing and flow control. Here we highlight recent contributions to the Sensors Special Issue series called “Microfluidics-Based Microsystem Integration Research” under the following categories: (i) Device fabrication to support complex functionality; (ii) New methods for flow control and mixing; (iii) Towards routine analysis and point of care applications; (iv) In situ characterization; and (v) Plug and play microfluidics.
Miniaturisation of Pressure-Sensitive Paint Measurement Systems Using Low-Cost, Miniaturised Machine Vision Cameras
Authors: Quinn Mark , Spinosa Emanuele , Roberts David
Published: July 2017

Measurements of pressure-sensitive paint (PSP) have been performed using new or non-scientific imaging technology based on machine vision tools. Machine vision camera systems are typically used for automated inspection or process monitoring. Such devices offer the benefits of lower cost and reduced size compared with typically scientific-grade cameras; however, their optical qualities and suitability have yet to be determined. This research intends to show relevant imaging characteristics and also show the applicability of such imaging technology for PSP. Details of camera performance are benchmarked and compared to standard scientific imaging equipment and subsequent PSP tests are conducted using a static calibration chamber. The findings demonstrate that machine vision technology can be used for PSP measurements, opening up the possibility of performing measurements on-board small-scale model such as those used for wind tunnel testing or measurements in confined spaces with limited optical access.
Unambiguous Imaging of Static Scenes and Moving Targets with the First Chinese Dual-Channel Spaceborne SAR Sensor
Authors: Jin Tingting , Qiu Xiaolan , Hu Donghui , Ding Chibiao
Published: July 2017

Multichannel synthetic aperture radar (SAR) is a breakthrough given the inherent limitation between high-resolution and wide-swath (HRWS) faced with conventional SAR. This paper aims to obtain unambiguous imaging of static scenes and moving targets with the first Chinese dual-channel spaceborne SAR sensor. We propose an integrated imaging scheme with the dual-channel echoes. In the imaging scheme, the subspace-based error estimation algorithm is first applied to the spaceborne multichannel SAR system, followed by the reconstruction algorithm prior to imaging. The motion-adapted reconstruction algorithm for moving target imaging is initially achieved with the spaceborne multichannel SAR system. The results exhibit an effective suppression of azimuth ambiguities and false targets with the proposed process. This paper verifies the accuracy of the subspace-based channel error estimator and the feasibility of the motion-adapted reconstruction algorithm. The proposed imaging process has prospects for future HRWS SAR systems with more channels.
Analysis of the Optimum Gain of a High-Pass L-Matching Network for Rectennas
Authors: Gasulla Manel , Jordana Josep , Robert Francesc-Josep , Berenguer Jordi
Published: July 2017

Rectennas, which mainly consist of an antenna, matching network, and rectifier, are used to harvest radiofrequency energy in order to power tiny sensor nodes, e.g., the nodes of the Internet of Things. This paper demonstrates for the first time, the existence of an optimum voltage gain for high-pass L-matching networks used in rectennas by deriving an analytical expression. The optimum gain is that which leads to maximum power efficiency of the rectenna. Here, apart from the L-matching network, a Schottky single-diode rectifier was used for the rectenna, which was optimized at 868 MHz for a power range from −30 dBm to −10 dBm. As the theoretical expression depends on parameters not very well-known a priori, an accurate search of the optimum gain for each power level was performed via simulations. Experimental results show remarkable power efficiencies ranging from 16% at −30 dBm to 55% at −10 dBm, which are for almost all the tested power levels the highest published in the literature for similar designs.
“Self-Employed” in Caregivinghood: The Contribution of Swedish Informal Caregivers’ Environmental and Contextual Resistance Resources and Deficits
Authors: Eriksson Monica , Wennerberg Mia , Lundgren Solveig , Danielson Ella
Published: July 2017

Informal caregivers provide the majority of care for older adults residing in their own homes. Caregivinghood, a new evidence-based concept, describes a time of life when relatives provide care at home. These caregivers need knowledge regarding resources to help them resolve the challenges they encounter. The theoretical framework underpinning this study is Antonovsky’s salutogenic theory of health. This study had two aims: (1) to examine the salutogenic core concepts Generalized and Specific Resistance Resources and Deficits (GRRs/SRRs and GRDs/SRDs) described by Swedish informal caregivers as originating from the environmental and contextual domain of caregivinghood and (2) to discuss how this new knowledge might contribute to the development of health promotion initiatives. This qualitative and theory driven study used inductive and deductive data analysis. Data were gathered through salutogenically guided face-to-face interviews of 32 Swedish informal caregivers. In addition, the study relied on the salutogenic core concepts Specific and Generalized Resistance Resources and Deficits originating from their environment and context. Being in empowering surroundings reflects the presence of usable SRRs/GRRs, whereas Struggling in impeding surroundings reflects the presence of SRDs/GRDs. The results indicate that health-enhancing support has to be individualized (SRRs/SRDs) and generalized (GRRs/GRDs). This study’s salutogenic approach and the methodology enhance the understanding of the mechanisms behind the development of Sense of Coherence. The results contribute both empirically and theoretically to strengthen health promotion research and practice when developing activities and support for caregivers in stressful situations, such as informal caregiving.

The evolution of the community law concerning biofuels is characterized by a late implementation of their support within the framework of the Common Agricultural policy (CAP). Moreover, their interest is today challenged considering the discovery of their many inconveniences which urged the Community institutions to slow down their support for biofuels. However, the promotion by these authorities of the use of the other biofuels is not excluded.
L’arrêt des usines de pâte à papier de la CIJ du 20 avril 2010 : un mode d’emploi pour violer des obligations procédurales sans peine
Authors: Sohnle Jochen
Published: July 2017

L’arrêt du 20 avril 2010 rendu dans l’affaire des usines de pâte à papier donne un mode d’emploi sur la manière de faire avaliser par la CIJ un fait accompli, après la violation d’obligations procédurales essentielles d’un traité sur l’eau. La banalisation des obligations procédurales permet à la Cour de ne décider qu’une réparation symbolique sous forme de satisfaction. Le conservatisme de la Cour en matière de preuve ne lui permet pas d’apprécier correctement le respect des obligations matérielles. La perception rétrograde de sa fonction lui interdit d’intervenir à titre préventif. Toutefois, deux apports de l’arrêt doivent être salués : la consécration en droit international de l’obligation d’évaluer l’impact sur l’environnement et la précision apportée au régime préventif de l’interdiction de causer un dommage à l’environnement d’un autre Etat.
Light-induced magnetoresistance in solution-processed planar hybrid devices measured under ambient conditions
Authors: Banerjee Sreetama , Bülz Daniel , Reuter Danny , Hiller Karla , Zahn Dietrich R T , Salvan Georgeta
Published: July 2017

We report light-induced negative organic magnetoresistance (OMAR) measured in ambient atmosphere in solution-processed 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) planar hybrid devices with two different device architectures. Hybrid electronic devices with trench-isolated electrodes (HED-TIE) having a channel length of ca. 100 nm fabricated in this work and, for comparison, commercially available pre-structured organic field-effect transistor (OFET) substrates with a channel length of 20 µm were used. The magnitude of the photocurrent as well as the magnetoresistance was found to be higher for the HED-TIE devices because of the much smaller channel length of these devices compared to the OFETs. We attribute the observed light-induced negative magnetoresistance in TIPS-pentacene to the presence of electron–hole pairs under illumination as the magnetoresistive effect scales with the photocurrent. The magnetoresistance effect was found to diminish over time under ambient conditions compared to a freshly prepared sample. We propose that the much faster degradation of the magnetoresistance effect as compared to the photocurrent was due to the incorporation of water molecules in the TIPS-pentacene film.

Published: July 2017

This research examines the existing of investor overconfidence in the capital market and the phenomena of stock prices reversal in the future due to the existing of this behavior. It has a different approach to test the existing of investor overconfidence by introducing firm’s growth as the information which has triggered many investors to behave overconfidently. By using multiple regression analysis, the results of this research confirmed our conducted hypothesis, investor tends to behave overconfident to firms which have higher growth. It proofed by the positive relation between firms’ growth and trading volume. Afterward, this research also found that higher growth firms tend to have declining on its performance in the future. The negative relation between firms’ growth and longterm performance means that the stock’s price reversal caused by the existing of investor overconfidence.

Background

Recent data have suggested that failure to achieve sustained virological response with direct-acting antiviral therapy is usually due to relapse and is primarily associated with the emergence of resistance-associated substitutions. The aim of this study was to investigate the prevalence and characterization of non-structural-5A resistance-associated substitutions in patients infected with HCV genotypes 1, 3 and 4 treated by direct-acting antiviral therapy, including anti-non-structural-5A, and to characterize the pre-existing resistance-associated substitutions in subjects treated with anti-non-structural-5A inhibitors.

Methods

From January 2014 to March 2016, 2,995 patients infected with HCV genotypes 1, 3 and 4 were exposed to non-structural-5A inhibitors. Sequencing results at the time of virological failure were available for 61 patients; sequencing at baseline was available for 35 of these patients.

Results

Among the 35 patients with sequencing results available at baseline, 15 had no resistance-associated substitution, 16 had only one resistance-associated substitution, and 4 had more than one resistance-associated substitution. Resistance-associated substitutions were harbored in 57% of the sequences in the non-structural-5A region. Among the 61 patients sequenced at virological failure, 50 (82%) patients presented at least one resistance-associated substitutions inducing a high level of resistance to non-structural-5A inhibitors (>10-fold resistance).

Conclusions

This pooled analysis suggests that non-structural-5A resistance-associated substitutions screening should be recommended when considering retreatment with a non-structural-5A inhibitor regimen in patients who have previously experienced failed non-structural-5A treatment.
Impetiginized Dyshidrotic Eczema

Published: July 2017

A 16 years old female patient, affected by atopic dermatitis and rhinoconjunctivitis allergica since childhood, requested a dermatologic consultation for lesions which had appeared after 3 months of local treatment with clobethasole propionate. The histological analysis confirmed the diagnosis of dyshidrotic eczema and the microbiological smears demonstrated a significant infection with Staphylococcus aureus. The risk of developing corticosteroids’ side-effects depends on the potency of the product, extended period of use and the volume of product applied. Clobetasol propionate is a group I- highly potent corticosteroid, which should be used for a maximum period of 2 weeks. Several authors have found that this agent has cumulative depot effect, persisting in the epidermis for 4 days after only one application. Taking together these observations, sustained by the clinical case presented above, we can conclude that the infectious risks associated with topical corticosteroid treatment must not be neglected, particularly since treated patients are fragile, and frequently have multiple well-known risk factors.

Published: July 2017

Primary of hereditary lymphedema is a rare but progressive disease. It is yet not curable. We present a 48-year-old male patient with hereditary lymphedema of his left leg, that was realised by minor trauma (able twist) when he was seven years old. He had never been treated for lymphedema but experienced multiple erysipelas during his life. After diagnostic procedures to exclude other causes of leg swelling, the diagnosis of hereditary lymphedema of the leg, stage III was confirmed. We initialized complex decongestive therapy. During two weeks of intensive treatment, the circumference of the left leg could be reduced by 10 cm. This case illustrates the "natural course" hereditary lymphedema. But it raises the hope that even after decades of ignorance, the patients benefits from complex decongestive treatment. Therapeutic nihilism is unnecessary and poses lymphedema patients to risks of infection and secondary malignancies like Stewart-Trewes syndrome.

Published: July 2017

The cutaneous dermatomycoses are among topical issues in all countries worldwide. They are registered in 20% of the world population. Dermatophyte infections incidence frequency varies depending on a season, region, effective anti-epidemic measures management, and effective treatment methods. In Kazakhstan in 2001, dermatophyte infections ranked second in the structure of dermatologic pathology in outpatients. According to the literature data, not so many research studies on dermatophyte infections have been carried out in our country within recent years. The importance of these issues suggests a need to conduct epidemiological, clinical, microbiological studies of dermatophytosis at the present stage. A cross-sectional study was conducted, in which 195 cases of dermatophytosis were collected and investigated in the regional hospital in Almaty for the period from the beginning of January 2014 to the end of December 2014. Dermatophytoses prevalence is observed in patients within the 1 - 39 age range.
First steps in the investigation of automated text annotation with pictures
Authors: Poots J. Kent , Cercone Nick
Published: July 2017

We describe the investigation of automatic annotation of text with pictures, where knowledge extraction uses dependency parsing. Annotation of text with pictures, a form of knowledge visualization, can assist understanding. The problem statement is, given a corpus of images and a short passage of text, extract knowledge (or concepts), and then display that knowledge in pictures along with the text to help with understanding. A proposed solution framework includes a component to extract document concepts, a component to match document concepts with picture metadata, and a component to produce an amalgamated output of text and pictures. A proof-of-concept application based on the proposed framework provides encouraging results
Sistemas complejos adaptativos y simulación computacional en Arqueología
Authors: Pardo-Gordó Salvador
Published: July 2017

Tradicionalmente el concepto “complejidad” se utiliza como sinónimo de “sociedad compleja” para referirse a grupos humanos que presentan determinadas características tales como urbanismo, desigualdad y jerarquización. Con la introducción de los Sistemas no lineales y de los Sistemas Complejos a la disciplina arqueológica dicho concepto está siendo matizado. Este viraje teórico ha supuesto el auge de las simulaciones computacionales como método de análisis de procesos históricos. Este trabajo tiene un doble objetivo: presentar la corriente teórica caracterizada por el pensamiento generativo que se está llevando a cabo en la disciplina arqueológica e ilustrar una aplicación concreta de la simulación computacional basada en agentes a un problema arqueológico: la dispersión de las primeras producciones cerámicas en el Mediterráneo occidental.

En el trabajo presentamos el nivel gravetiense de Coímbre, uno de los contados ejemplos de esta cronología en el centro-occidente cantábrico. Se trata de uno de los yacimientos de mayor interés para el análisis del Gravetiense cerca de su margen occidental de expansión por el continente europeo. Mediante el análisis arqueozoológico y tafonómico de la fauna, de la industria lítica, los restos arqueobotánicos, la interpretación de la secuencia arqueológica y sedimentológica, y la obtención de dataciones AMS, se han podido analizar las ocupaciones gravetienses de Coímbre bajo una perspectiva territorial, donde las estrategias de susbsistencia desarrolladas son determinantes para interpretar el tipo de ocupación existente. En el marco de la región cantábrica, podemos interpretar la existencia de un patrón de movilidad y subsistencia determinado, desarrollado por estas poblaciones humanas, que se manifiesta como una ocupación efímera, de tipo logístico y puntual, ligada posiblemente con un eje de tránsito en sentido este-oeste. Esto supone uno de los elementos de mayor interés que aporta este estudio.

El Rebollosillo es una pequeña cueva kárstica situada en el centro de la Península Ibérica utilizada para la disposición de enterramientos secundarios en la mitad del III milenio AC. Presentamos resultados bioantropológicos, isotópicos (87Sr/86Sr, δ13C y δ18O) y 16 dataciones radiocarbónicas de los restos humanos, una descripción cuantificada de los 43 fragmentos cerámicos y de caracterización mineralógica de 6 cuentas recuperadas durante la excavación de 1989, cuatro de las cuales probablemente proceden de Palazuelo de las Cuevas (Zamora). El análisis bioantropológico indica un mínimo de 21 individuos con todos los rangos de edad y sexo. Se han detectado bajos porcentajes de patologías, mayoritariamente cálculo dental y caries, con casos puntuales de cribra orbitalia, periostosis y artrosis. La disposición de los restos sugiere que sólo los adultos recibieron un tratamiento claramente individualizado, quizás acorde con un estatus adquirido con la edad. Proponemos que el registro representa la última fase de un programa mortuorio cuyas etapas previas debieron desarrollarse en otros lugares y valoramos estos resultados en el contexto del registro funerario regional.
La I Edad del Hierro en la cuenca media del Duero: arquitectura doméstica y formas de poder político durante la Facies Soto (siglos IX-VII a.C.)
Authors: Arnaiz Alonso Miguel Ángel
Published: July 2017

El texto analiza las trasformaciones de la arquitectura doméstica durante el tránsito entre la Fase Inicial y Plena de la Facies Soto, I-Edad del Hierro en el sector central de la cuenca del Duero. Se conectan tales modificaciones con los cambios políticos desarrollados en comunidades autosuficientes estructuradas bajo el Modo de producción doméstico. El nuevo marco político conlleva trastornos en las relaciones de reproducción social basadas en intercambios simétricos, sustituidas por otras de carácter competitivo y en intercambios asimétricos. Se examina la relación de estos últimos con alianzas establecidas con comunidades foráneas y la contribución al proceso de transformación que tienen las ideas y los materiales exóticos procedentes de las relaciones externas.

Published: July 2017

El objetivo del presente trabajo es analizar la incidencia y funcionalidad de las deposiciones monetales en las tumbas de la necrópolis tardopúnica de Gadir. Para ello, se ha llevado a cabo una sistemática extracción de la información contenida en las memorias de las intervenciones arqueológicas urbanas depositadas en la Delegación de Cultura de Cádiz. El examen detenido de estos datos, muchos inéditos, nos ha permitido acercarnos a la participación del numerario en los diferentes actos que componían los ceremoniales de enterramiento, tanto en inhumaciones como en cremaciones, como testimonio de un variado elenco de momentos rituales en los que la moneda tuvo un papel peculiar. Si bien son escasos, los testimonios abordados muestran de qué forma el numerario se incorporó de manera multifacética a las creencias y escatologías del tradicional ceremonial funerario fenicio en Gadir.

Hemos empleado fluorescencia de rayos X por energía dispersiva (EDXRF), emisión de rayos X inducida por partículas (Micro-PIXE) y microscopía (análisis metalográfico), complementada con microscopia electrónica de barrido y espectroscopia de rayos X en energía dispersiva (SEM-EDS), primero para determinar el contenido elemental y segundo para identificar el proceso empleado para unir los componentes (disco, anillo periférico y presilla) de varios de los discos de oro de la Edad del Hierro. Su tipología es muy similar y fueron encontrados en tres yacimientos arqueológicos de la zona suroccidental de la Península Ibérica. Una serie de 35 discos del Castro dos Ratinhos (7), Outeiro da Cabeça (23) y Fortios (5) fueron analizados y sus resultados publicados en Trabajos de Prehistoria (Soares et al. 2010). Recientemente Perea et al. (2016) han publicado análisis de otros 4 discos de oro de Fortios con el mismo propósito pero usando solo SEM-EDS. Al haber analizado solo la capa superficial irregular, los resultados no son reales, ni fiables, considerando las limitaciones asociadas con la técnica, especialmente la escasa profundidad alcanzada (< 2 ?m) por el haz incidente y, consecuentemente, su sensibilidad a la topografía de la superficie analizada. A pesar de esas limitaciones, han aceptado acríticamente sus resultados y, a la vez, han puesto en cuestión nuestros análisis y resultados y las interpretaciones que hemos hecho. Aquí discutimos el enfoque de Perea et al. para determinar no solo el contenido elemental de los discos de oro de Fortios, sino también para identificar el proceso de unión empleado en su manufactura.
A Localization Algorithm of Wireless Sensor Network Based on Statistical Uncorrelated Vector
Authors: Wang Min
Published: July 2017

For exploring wireless sensor network - a self-organized network, a new node location algorithm based on statistical uncorrelated vector (SUV) model, namely SUV location algorithm, is proposed. The algorithm, by translating the node coordinate, simplifies the solution to double center coordinate matrix, and gets the coordinate inner product matrix; then it uses statistical uncorrelated vectors to reconstruct the coordinates of the inner product matrix and remove the correlation of inner matrix of coordinates caused by the ranging error, so as to reduce the impact of ranging error on subsequent positioning accuracy. The experimental results show that the proposed algorithm does not consider the network traffic, bust still has good performance in localization. At last, it is concluded that reducing the amount of communication of sensor nodes is beneficial to prolong the service life of the sensor nodes, thus increasing the lifetime of the whole network.

Authors: Zhang Na
Published: July 2017

The hierarchical distributed network topology combined with traditional wireless routing algorithm is adopted and improved by through introducing energy model of FSO sensor network to study the method of extend network nodes life in special occasion. The OEEMRP protocol (Optical Efficient Energy Multi-Path Routing Protocol) is also proposed. The protocol also can save the node energy and improve the network survival time. In the simulation, we compare and analyze performance difference of death node number and residual energy in LEACH and OEEMRP algorithm. The result shows that improved routing algorithm can make network node more intensive, and in the condition of large network size, the performance will be improved significantly. In a word, it has significant role in network communication.

A logistics monitoring technology is proposed based on the analysis for the traditional logistics enterprises. By tracking the existing monitoring system and data transmission technology, a new technology WSN-based logistics vehicle monitoring system is adopted. The practical significance to monitoring and managing the logistics processes effectively is to diminish transportation costs, improve logistics efficiency and avoid needless economic loss. The results show that the WSN not only realizes the positioning of the vehicle, but also can effectively manage the goods, improve the efficiency in the transportation management of the goods. In addition, this experiment system also adds a temperature sensitive alarm circuit to improve the safety performance of the terminal. Based on the result, it is concluded that this technology can adjust the transmission power and reduce energy consumption to extend the network life cycle as long as possible.

Internet of Things
Authors: Oriwoh Edewede , Williams Geraint
Published: July 2017

The Internet of Things (IoT), a metaphor for smart, functional Cyberphysical Environments (CPE), is finding some usefulness in various sectors including healthcare, security, transportation, and the Smart Home (SH). Within the IoT, objects potentially operate autonomously to provide specified services and complete assigned tasks. However, the introduction of new technologies and/or the novel application of existing ones usually herald the discovery of unfamiliar security vulnerabilities, which lead to exploits and sometimes to security breaches. There is existing research that identifies IoT-related security concerns and breaches. This chapter discusses existing Digital Forensics (DF) models and methodologies for their applicability (or not) within the IoT domain using the SH as a case in point. The chapter also makes the argument for smart forensics, the use of a smart autonomous system (tagged the Forensics Edge Management System [FEMS]) to provide forensic services within the self-managed CPE of the SH.

Artificial Organs
Authors: Catapano Gerardo , Verkerke Gijsbertus Jacob
Published: July 2017

The market of tools, devices, and processes for medical treatments and diagnosis has been growing at a very fast pace, driven by the multi-disciplinary development of integrated innovative technologies. In this article, the way artificial organs design is currently taught is analyzed and discussed relative to the evolution of the methods of artificial organs design as substitution of physical and metabolic bodily functions. Particular attention is devoted to the evolution from empirical attempts at providing generic replacement of a single mechanical function to a more systematic multi-purpose approach that increasingly accounts for biological issues. As a result, at the forefront of research, the paradigm is shifting from mechanical/electronic prostheses towards the development in vitro of tissue engineered organs/tissues, where the artificial part is fully integrated with the biological counterpart. Personalized solutions for each patient rather than a generic solution good for all patients are also sought.

In this paper reduce power of multichannel fractional sample rate convertor by minimized hamming distance between consecutive coefficients of filter using Genetic algorithm. The main component of multichannel fractional sample rate convertor is Cascaded multiple architecture finite impulse response filter (CMFIR filter). CMFIR is implemented by cascading of cascaded integrator-comb (CIC) & multiply accumulate architecture (MAC) FIR filter. Genetic algorithm minimizes the hamming distance between consecutive coefficients of CMFIR filter. By Minimizing the hamming distance of consecutive filter coefficient reduces the transaction from 0 to 1 or 1 to 0. These techniques reduce the switching activity of CMOS transistor which is directly reduces Dynamic power consumption by multichannel sample rate convertor, it also minimizes the total power consumption of multichannel fractional sample rate convertor. later than use genetic algorithm on 1 to 128 channel Down sample rate convertor total power reduced by 3.44% to 61.56%, dynamic power reduced by 9.09% to 56.25% .1 to 128 channel Up sample rate convertor total power reduced by 2.81% to 45.42%, dynamic power reduced by 4.76% to 56%, 1 to 128 channel fractional sample rate convertor total power reduced by 1.44% to 17.17%, dynamic power reduced by 6.25% to 19.92%.

The aim of this study is to highlight the morphology of the second maxillary molars root canals and to draw a comparison between the data obtained with and without magnifying means.
The study covered a total of 31 extracted human second maxillary molars. After being examined by a thorough physical exam and an X-ray examination, teeth were trepanned in the place of election. Thereby the access cavity was performed using: a) for the stage of pulp chamber ceiling penetration, a globular diamond bur for the turbine, b) for the stage of broadening access cavity, a cylindrical bur inactive in the head for the opposite-angle piece and c ) a Batt bur for the flaring and finishing stage.Afterwards, the sighting of the main root canals was performed using the endodontic probe or Miller file. Examination and sighting of the additional canals was made under magnification using the dental microscope.
The molars with three canals had the highest prevalence of endodontic morphology of two upper molars (90.32%). But there were special cases with two channels morphology (6.45%) and four channels morphology (3.22%). After examining the endodontic space under the microscope, there have been identified and secondary canals, approximately 32.25% of molars examined presenting one or more secondary canals.
The anatomy of the most frequent upper second molar was three roots with three root canals; the most common variation in morphology is the presence of an mesiobuccal additional canal (MB2). However, we can encounter an unusual number of canals.
The importance of magnification, of the dental microscope in our study cannot be ignored because using only the latter we could highlight the real endodontic morphology of the two upper molars extracted examined, finding additional canals in 32.25% of the molars undergoing examination.

Objective: The management of chronic prostatitis/ chronic pelvic pain syndrome type III (CP/CPPS) has been always considered complex due to several biopsychological factors underling the disease. In this clinical study, we aimed to evaluate the efficacy of the treatment with Curcumin and Calendula extract in patients with CP/CPPS III. Material and methods: From June 2015 to January 2016 we enrolled 60 consecutive patients affected by CP/CPPS III in our institution. Patients between 20 and 50 year of age with symptoms of pelvic pain for 3 months or more before study, a total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score ≥ 15 point and diagnosed with NIH category III. Patients were then allocated to receive placebo (Group A) or treatment (Group B). Treatment consisted of rectal suppositories of Curcumin extract 350 mg (95%) and Calendula extract 80 mg (1 suppository/die for 1 month). Patients of Group B received 1 suppository/die for 1 month of placebo. The primary endpoint of the study was the reduction of NIH-CPSI. The secondary outcomes were the change of peak flow, IIEF-5, VAS score and of premature ejaculation diagnostic tool (PEDT). Results: A total of 48 patients concluded the study protocol. The median age of the all cohort was 32.0 years, the median NIH-CPSI was 20.5, the median IIEF-5 was 18.5, the median PEDT was 11.0, the median VAS score was 7.5 and the median peak flow was 14.0. After 3 months of therapy in group A we observed a significant improvement of NIH-CPSI (-5.5; p < 0.01), IIEF-5 (+ 3.5; p < 0.01), PEDT (-6.5; p < 0.01), peak flow (+2.8; p < 0.01) and VAS (-6.5; p < 0.01) with significant differences over placebo group (all p-value significant). Conclusions: In this phase II clinical trial we showed the clinical efficacy of the treatment with Curcumin and Calendula in patients with CP/CPPS III. The benefits of this treatment could be related to the reduction of inflammatory cytokines and of inflammatory cells. These results should be confirmed in further studies with greater sample size.

Objectives: The aim of this study is to evaluate the effects of the herbal agent in the prevention and treatment of bacterial cystitis in a rat model. Material and Methods: A total of twenty-eight male Sprague- Dawley rats were divided into four groups. Group-1 constituted the control group (operated and normal saline injected into the bladder, received only drinking water for 7 days); Group-2 constituted the no-treatment group (operated, E.coli J96 strain injected into the bladder, received only drinking water for 7 days); Group-3 constituted the short-term treatment (operated, E.coli J96 strain injected into the bladder, received the herbal agent added into drinking water for 7 days) and Group-4 constituted the long-term treatment (operated, E. coli J96 strain injected into the bladder, received herbal agent added into drinking water for 14 days). At the end of the pre-defined treatment periods of duration, the rats were sacrificed, urine samples collected from the bladder for culture and bladders were harvested for histopathological evaluation. Urine culture results and histopathological findings were comparatively evaluated between the groups. Results: Urine cultures were positive for implanted E. coli strains in 0%, 85.7%, 42.8% and 0% of rats in Group 1, Group 2, Group 3 and Group 4, respectively (p = 0.001). Although histopathological evaluation revealed increased vascular dilation in the bladder specimens obtained from Group 2 and Group 3 (p = 0.028) no significant difference was noticed in level of inflammation (p = 0.610), edema (p = 0.754) and thickness of uroepithelium (p = 0.138). Conclusion: While long term (14 days) treatment with an herbal agent added into the drinking water resulted in complete clearance of urine from E. coli; shorter application of the agent revealed partial clearance. Further clinical studies are needed to support our results.

Objective: The objective of the study is to report the outcome of buccal mucosal urethroplasty. Materials and methods: The follow up data of 15 patients undergoing single stage urethroplasty from September 2010 to September 2015 were retropectively reviewed. They received buccal mucosa graft for urethroplasty. The patients were followed for complications and outcome. Results: Mean age was 53.7 ± 13.6 The stricture length ranged from 3 to 6 cm (mean 4.4 ± 0.8). The success rate for buccal mucosa urethroplasty (BMU) was 67.7% at 12th month. Three patients presenting with voiding difficulty in the 3rd month and one in the next 12 months, had urethral restenosis. One patient had fistula formation at 6th month postoperatively. Five patients underwent retreatment procedures such as internal urethrotomy, urethroplasty and/or internal urethrotomy. Conclusions: The buccal mucosa is easy to obtain and handle, therefore BMU can be safely and effectively managed outside high volume institutions.

Anaplastic seminoma (AS) is an uncommon histological variant of classical seminoma of the testis and account for 5%-15% of cases. It is poorly described in the scientific literature. We present the case of a 50-years-old homeless man presenting with fever, marked left scrotal hardness and a fungating left scrotal lesion. He underwent left orchiopexy 40 years before. A computed tomography with contrast media showed a suspect testis cancer with scrotal involvment, extensive intralesional necrosis and multiple systemic metastases. A wide excision of the left hemiscrotum including the testis was performed in order to prevent severe local and systemic infectious complications. Histological examination revealed an AS. General conditions showed a rapid deterioration and the patient died on post operative day 10.

There are very few reported cases of traumatic amputation of the male genitalia due to animal bite. The management involves thorough washout of the wounds, debridement, antibiotic prophylaxis, tetanus and rabies immunization followed by immediate reconstruction or primary wound closure with delayed reconstruction, when immediate reconstruction is not feasible. When immediate reconstruction is not feasible, long-term good functional and cosmetic results are still possible in the majority of cases by performing total phallic reconstruction. In particular, it is now possible to fashion a cosmetically acceptable sensate phallus with incorporated neourethra, to allow the patient to void while standing and to ejaculate, and with enough bulk to allow the insertion of a penile prosthesis to guarantee the rigidity necessary to engage in penetrative sexual intercourse.
