High-affinity capturing of tagged proteins on the switch SENSE ® biochip using Strep-Tactin ® XT Application

Capturing proteins on a biosensor surface via tags is convenient, as many proteins are expressed with tags for purification. The most common tag is the polyhistidine tag, which can be captured by a tris-NTA modified surface with a KD in the nanomolar range. This capture system works well for interactions featuring affinities which are weaker than the aforementioned KD, but for the measurement of high-affinity interactions with slow dissociation rates below 10 s, the His6-NTA3 complex is not stable enough. In contrast, the recently introduced Strep-Tactin®XT – Twin-Strep-tag® system by IBA GmbH forms an exceptionally strong complex with a KD in the picomolar concentration range. Strep-Tactin®XT is a specifically engineered streptavidin variant with high affinity towards the synthetic Strep-tag®II peptide sequence (WSHPQFEK). Due to the avidity effect, even tighter binding can be achieved with the Twin-Streptag®, which consists of two Strep-tag®II motifs in series (WSHPQFEK-(GGGS)2GG-SA-WSHPQFEK). In enabling the measurement of long dissociation times and the analysis of slow off-rates, this tag system is a promising means to stably immobilize Strep-tagged® proteins on biosensors.
Experiences and Perceptions on Needle Stick Injuries among Staff Nurses in a Private Hospital in Singapore

This study identified experiences and perceptions on needle stick injuries among staff nurses in a private hospital in Singapore. A cross sectional descriptive-analytical study design was conducted from December 2016 to January 2017. Survey questionnaires were distributed to 100 nurse respondents from Accident and Emergency (n=32), Medical-surgical ward (n=30), Operation theater (n=16), and Obstetrics and Gynecology (OB-Gyne) ward (n=22) who were conveniently selected. Of the 100 self-administered questionnaires, only n=71 were used. Needle stick injuries were more affected by the hospital department (RR 1.01) followed by the age group (RR 0.99) and years of clinical practice (RR 0.88). The experience with needle stick injury was probable (p=0.02; 56.52%). There are identified perceptions on needle stick injury in this study such as adequate staff nurses in a shift (p=0.02), hospital awareness (p=0.04), injection safety equipment (p=0.04) and adequate mentor and supervisor (p≥0.05).

Distributed Minimization of the Power Generation Cost in Prosumer-Based Distribution Networks

Traditionally, electrical power was generated in big power plants. The cost of producing energy was related to the cost of fuel, e.g., carbon or gas, and by the cost of maintaining the power plants. With the advent of distributed energy resources, power can be produced directly at the edge of the electrical network by a new type of agent: the prosumer. Prosumers are entities that both consume and generate power, e.g., by means of photovoltaic panels. The cost of the power produced by prosumers is no longer related to fuel consumption since energy coming from distributed generators is essentially free. Rather, the cost is related to the remuneration that is due to the prosumers for the services they provide. The proposed control strategy minimizes the active power generation cost in the aforementioned scenario. The control scheme requires that the prosumers measure their voltage and then adjust the amount of injected power, according to a continuous time feedback control law that is a projected gradient descent strategy. Simulations are provided to illustrate the algorithm behavior.

An investigation of change effort in two evolving software systems

Making changes to software systems can prove costly and it remains a challenge to understand the factors that affect the costs of software evolution. This study sought to identify such factors by investigating the effort expended by developers to perform 336 change tasks in two different software organizations. We quantitatively analyzed data from version control systems and change trackers to identify factors that correlated with change effort. In-depth interviews with the developers about a subset of the change tasks further refined the analysis. Two central quantitative results found that volatility of requirements and dispersion of changed code consistently correlated with change effort. The analysis of the qualitative interviews pointed to two important, underlying cost drivers: Difficulties in anticipating side effects of changes and difficulties in comprehending dispersed code. This study demonstrates a novel method for combining qualitative and quantitative analysis to assess cost drivers of software evolution. Given our findings, we propose improvements to design practices and development tools to reduce the costs.

Experimental results obtained by this method are compared with already implemented successful approaches and limitations of others approaches overcome by this method are discussed.
Synergetic Effect of Nano-ZnO and Trinidad Lake Asphalt for Antiaging Properties of SBS-Modified Asphalt

In order to address the influence of aging on the performance degradation of SBS-modified asphalt, a composite modification of SBS-modified asphalt by nano-zinc oxide (nano-ZnO) and Trinidad Lake asphalt (TLA) was proposed. Several tests were conducted after adding nano-ZnO and TLA to SBS-modified asphalt, including a rotary film oven test (RTFOT), ultraviolet aging (UV), and the pressure aging vessel test (PAV). The conventional physical index, rheological index, and four-component content of SBS-modified asphalt before and after three aging modes were tested, and the characteristic functional groups in SBS-modified asphalt were tracked and analyzed by Fourier transform infrared spectroscopy (FTIR). The results show that the effects of aging on the rheological properties of SBS-modified asphalt are clearly reduced by adding different proportions of nano-ZnO and TLA in the process of thermal oxygen aging and the ultraviolet aging test, and the antiaging ability of SBS-modified asphalt is clearly improved. To improve the conventional performance and rheological properties of SBS-modified asphalt, an incorporation ratio of 3% nano-ZnO + 25% TLA was proposed. At the same time, the increased rate of heavy components and the change index of the colloidal instability index in the SBS-modified asphalt under the blending ratio were significantly lower than the blank SBS-modified asphalt samples in the same aging mode. FTIR spectra also showed that SBS-modified asphalt performance deterioration were mainly caused by long-term aging and ultraviolet aging. The addition of nano-ZnO and TLA effectively reduced the increase of carbonyl groups and the breakage of the C=C double bond in butadiene and synergistically improved the comprehensive aging resistance of SBS-modified asphalt. Therefore, the use of this modification is an effective method to solve the aging problem of SBS-modified asphalt.
Straightness-of-path during and after vernal migration in prairie rattlesnakes, Crotalus viridis, in eastern Colorado

Understanding movement patterns in regards to habitat and resource availability can provide significant insight on the utilization of an animal’s habitat. Further, movements in response to foraging or environmental constraints may drastically increase risk to predation as well as prove to be energetically costly for migrating individuals. Detailed radio telemetry studies in rattlesnake ecology have illuminated differences in seasonal patterns of migration, as well as movements related to prey locations, mate searches, and reproductive behaviors. Measurements of home ranges, travel distances and directions, and straightness-ofpath provide useful ecological information about snake movement (Gregory, Macartney and Larsen, 1987). However, varying habitats and resource availability may lead to distinct movement patterns of conspecifics in different geographical locations. Movements of prairie rattlesnakes (Crotalus viridis; nomenclature follows Crother, 2008) in the United States have been especially well studied (see Jorgensen, Gates and Whiteside, 2008), although to a much lesser degree throughout the Great Plains region. Shipley et al. (2013) investigated movements of an eastern Colorado population of C. viridis in conjunction with Blacktailed prairie dog (Cynomys ludovicianus) colonies revealing movements that were short (mean = 648 m), relatively straight, with frequent changes in direction. However, Duvall, King and Gutzwiller (1985) showed that C. viridis in Wyoming exhibited a remarkable straightness-of-path while moving significantly farther Herpetology Notes, volume 7: 425-436 (2014) (published online on 5 July 2014)
Comparative Study of Anxiety Disorders and Personality Disorders in Obsessive-Compulsive Disorder

The purpose of this paper is to provide evidence for the relationship between personality disorders (PDs), obsessive compulsive disorder (OCD), and other anxiety disorders different from OCD (non-OCD) symptomatology. Method: The sample consisted of a group of 122 individuals divided into three groups (41 OCD; 40 non-OCD, and 41 controls) matched by sex, age, and educational level. All the individuals answered the IPDE questionnaire and were evaluated by means of the SCID-I and SCID-II interviews. Results: Patients with OCD and non-OCD present a higher presence of PD. There was an increase in cluster C diagnoses in both groups, with no statistically significant differences between them. Conclusions: Presenting anxiety disorder seems to cause a specific vulnerability for PD. Most of the PDs that were presented belonged to cluster C. Obsessive Compulsive Personality Disorder (OCPD) is the most common among OCD. However, it does not occur more frequently among OCD patients than among other anxious patients, which does not confirm the continuum between obsessive personality and OCD. Implications for categorical and dimensional diagnoses are discussed.
An Optimization to YOLOv3 Detection of Small, Fast Moving Objects

— A project to obtain tennis statistics based on tennis ball tracking led us on a search to ﬁnd real time object detection on small, fast moving objects. Realizing there were no methods available that satisﬁed our requirements, we optimized the detection method that came closest, YOLOv3 tiny [You Only Look Once Version 3 Tiny], to come up with YOLOOv3 tiny [You Only Look Once, Optimized]. YOLOv3 tiny is the third iteration of a Computer Vision application that is used to detect objects in real time. However, it is limited by the size and speed of the object relative to the camera’s position along with the detection of False Positives due to incorrect localization. In this paper, we explore optimization techniques to extend the use of YOLOv3 tiny to accurately detect small, fast The techniques discussed in the paper were tested on detecting a tennis ball moving up to 160kmph with a minimum angular size of 0.414 degrees at a rate of 30 frames per second. The accuracy was found to be 95.268% on a video containi sampled at 30 frames per second (assuming the object is always in the frame) on a GeForce 1050 Graphics Processing Unit. This optimization includes a method of elimination of false positives to increase accuracy.
Performance Evaluation of Symmetric Data Encryption Algorithms: AES and Blowfish

People are transferring large amount of data that are critical and consume large amount of time through the Internet such as email, banking transaction and online purchase. But due to high exposure they are susceptible to being heavily attacked or become attractive targets for attackers. This can be solved by using a modern phenomenon called symmetric encryption. Symmetric encryption is used to ensure that information is hidden from anyone for whom it is not intended. This research conducted a performance evaluation of symmetric data encryption algorithms namely Advanced Encryption Standard (AES) and Blowfish. The evaluation is done for four different data types: image data type, audio data types, video data types and textual file data types. The performance evaluation metrics are encryption time and throughput. The prototype is developed using JAVA, compiled using the Netbeans IDE7.1. 2 with default settings in jdk 7.1 development kit. Results obtained from this evaluation indicated that blowfish is more efficient than AES. But for Blowfish the encryption time sometime decreases with the increase in data size. This can be attributed to the fact that Blowfish uses 126, 192 or 256 key sizes.
STRENGTH ANALYSIS OF ZNO-AL2O3 NANOCOMPOSITE FOR IMPLANT MATERIAL INNOVATION

Nowadays, implant material become an attractive attention for the researchers to look for alternative materials that better than the previous material. Several complaints have been found due to the use of titanium and steel as implants in the knee. Composite is the main option and being the center of attention and nanomaterials are a promising new breakthroughs. This study offers a new solution for the knee implant in the form of ZnO-Al2O3 nanocomposite as knee implant material. Before being applied to the world of orthopedics, the nanocomposite has been tested using a mechanical testing using hydraulic press machine and has done the compressive strength and shear simulated using software simulation with Catia Version 5 Release 17 (V5R17) and ANSYS. The results of the compressive strength of composites with different percentage comparisons showed that 50% ZnO and 50% Al2O3 has the highest compressive strength compared to other composition ratio (80-20 and 65-35). Based on simulation data, ZnO-Al2O3 nanocomposite has the highest strength on the composition ratio of 50% ZnO and 50% Al2O3 which has the ability to withstand a compressive stress of 3 GPa, equivalent to 300 x 107 N / m2.
PESARO 2012

—An opportunistic grid computing environment takes advantage of idle computing cycles of regular computers and workstations that can be spread across several administrative domains for running high performance applications. Opportunistic grids are usually constructed from personal computers that do not need to be dedicated for executing grid applications. The grid workload must coexist with local applications executions, submitted by the nodes regular users. Thus, its execution environment is typically dynamic, heterogeneous and unpredictable failures occur frequently. In addition, the resources of an opportunistic grid can be used at any time for the execution of local tasks, making it difﬁcult to preview the conclusion of the tasks running on the grid nodes. These characteristics hinder the successful execution of applications for which there are time restrictions related to its completion. This paper presents a management mechanism speciﬁcally designed for opportunistic grid computing environments for handling the execution of applications with time deadlines set by users during their submission to the system. The proposed mechanism is based on a dynamic scheduling and rescheduling approach and was evaluated using a simulated model considering various typical scenarios of opportunistic grids. The results demonstrated the beneﬁts of the proposed approach in comparison to traditional scheduling approaches applied in opportunistic grids.
Optimizing Bw-tree Indexing Performance

—The Bw-tree is a latch-free, B-tree style index that is part of Deuteronomy key-value stores, which have been deployed both in the cloud and in “boxed” products. It can be layered on a log structured storage manager or used as a main memory index, and it can support transactions when embedded in a system with a Deuteronomy transactional component. Its high performance is a result of its latch-free, log structured properties, coupled with an intelligent but straightforward implementation of index search. In this paper, we present our optimized Bw-tree index that is substantially faster than our initial implementation. We apply an integrated set optimizations, new ones and reﬁnements of prior techniques, to produce Bw-tree indexing with up to 40 percent better performance for single key lookups, while also improving range search performance. And our original implementation performs comparably to the best main memory indexes. Uniquely, however, it is designed to be used with data residing on secondary storage, and hence includes the overheads required to keep data paginated.

Survey on Applications of Electronic Nose

Food plays a vital role in our daily life. Providing good quality food to consumers is essential. Food quality can be accessed using the Electronic nose. Electronic nose (E-nose) is an instrument for odor analysis. E-nose mimics the human olfaction system. It is widely used in predicting the quality of foodstuffs and detecting the contamination in foods. E-nose can also be used in outdoor monitoring such as air quality monitoring and detect the hazardous odors emitted wastewater treatment plants. Application of E-nose is increasing day by day. In this paper, we consolidated the previous works on E-nose. They had applied different machine learning algorithms to construct a model. In most of the works, for the classification of data, they used Support Vector Machine and Linear Discriminant Analysis, which shows higher accuracy when comparing to other algorithms.
Relationship between Perceived Parenting Styles and Psychological Well-Being of Ao/Naga Adolescents

Parenting styles adopted during the period of adolescence are expected to be extremely vital in determining the well-being of the children as they undergo significant physical, emotional, psychological and behavioral changes. In view of this, the present study was undertaken to investigate the relationship between the perceived parenting styles of Ao/Naga parents with the psychological well-being of the adolescents. A correlational research design was adopted for the study with a multi-stage sampling technique used for sampling. The total sample of the study consisted of 200 Ao/Naga Adolescents from Kohima District, Nagaland. Parental Authority Questionnaire and Ryff Psychological Well-Being Scale were the tools used to collect the data. Results revealed authoritative parenting to be the predominant parenting style adopted by mothers (77%) and fathers (72%). Perceived parenting styles of mothers and fathers were found to be a strong predictor of the psychological well-being of the female and male adolescents respectively. Perceived authoritative parenting style of mothers and fathers predicted the psychological well-being of female adolescents. Also, it was reported that the perceived authoritarian parenting style of fathers predicted low psychological well-being score amongst male adolescents. Limitations and implications of the study have been discussed. Acknowledgment: I would like to acknowledge and thank the financial funding (Centrally Sponsored Doctoral Fellowship) granted to me by the Indian Council of Social Science Research (ICSSR), New Delhi for undertaking this research study Introduction Parenting is a complex process in which a parent uses different behaviors to influence their children (Darling 1999). According to Bradley and Caldwell (1995), it is through the mode of parenting that parents shape their children to be able to live in society and adapt to it as well as helping them to reach their potential. Thus, the influence of parents on the lives of their children is immensely crucial.
