A New Furanoheliangolide Sesquiterpene Lactone from Calea pinnatifida (R. Br.) Less. (Asteraceae) and Evaluation of Its Trypanocidal and Leishmanicidal Activities

Calea pinnatifida (R. Br.) Less. is commonly known in Brazil as "cipo-cruz", "quebra-tudo" or "aruca". This species is employed in folk medicine as giardicidal, amoebicidal and to treat digestive disorders. The present paper describes the isolation and structure determination of a new furanoheliangolide sesquiterpene lactone named 11,13-dihydroxy-calaxin, in addition to seven known compounds: ethyl caffeate, vanillin, 12-hydroxy-encecalin, phytol, 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid from the ethanol extract of C. pinnatifida leaves. Additionally, 11,13-dihydroxy-calaxin, vanillin, 12-hydroxy-encecalin, phytol, 3,4-di-O-caffeoylquinic acid, 4,5-di-O-caffeoylquinic acid and the mixture of 3,4-di-O-caffeoylquinic, 3,5-di-O-caffeoylquinic and 4,5-di-O-caffeoylquinic acids were assayed against the amastigote forms of Leishmania amazonensis and Trypanosoma cruzi, and the sesquiterpene lactone 11,13-dihydroxy-calaxin exhibited a promising trypanocidal and leishmanicidal activity, displaying IC50 values of 5.27 and 8.30 µM, respectively.
PEER LEARNING WITH SMALL MEANS: A CASE STUDY OF IMPLEMENTING PEER LEARNING IN A LABORATORY EXERCISE

Peer learning in teaching is a common method which makes students share their problems and learn from each other. It is often used to increase studentsunderstanding and level of deep learning. In this study, the peer learning concept has been applied to a laboratory exercise and a comparative study has been performed. The study consists of two cases, a reference group, which performed the exercise in a traditional way, and a peer learning group, which performed the exercise in a modified way. In the peer learning group, the students were encouraged to ask each other for help and an additional presentation was added in order to further increase the interaction between students. The outcome was evaluated through classroom observations, a questionnaire, and a short knowledge test. The results show that the peer learning approach had different positive effects. When the students were instructed to ask each other for help, there was an apparent change in the studentsbehaviour. The students in the peer learning group were more active and more creative compared to the reference group. They also had better results on the knowledge test and were more satisfied with the exercise. This demonstrates that small changes to an existing laboratory exercise can increase the understanding, involvement and creativity of the students. In this case, this was also achieved without an extended workload on the teacher.
Design of a small reverberation box based on BEM-SEA method

The reverberation chamber which was used to test sound absorption and insulation performance in the reverberation space had the following problems. Firstly, the construction cost of the reverberation chamber was high. Secondly, the test can’t be completed when the size of the specimen was too small. As a result, a small reverberation box with a relatively small size had significant meaning. The previous researchers designed the small reverberation box by using the traditional experience and theory formulas which had a long period and high cost. In order to solve this problem, simulation analysis on sound insulation performance of a compound structure through Statistical Energy Analysis (SEA) was proposed. And then the sound field distribution of the small reverberation box was simulated by Boundary Element Method (BEM). According to the simulation results, the model was optimized repeatedly. And finally a small reverberation box model with sufficient sound insulation performance and uniform sound field was obtained. The actual structure was made based on simulation model, and its sound characteristic was tested. The results showed that the small reverberation box had an excellent performance. BEM-SEA method was feasible to be used to design a small reverberation box.
Assessment of theoretical and practical aspects of the Salsnes filtration unit

ABSTRACT Salsnes Filter delivers a technology used for primary treatment of wastewater. The technology could be described as a rotating belt sieve with continuously air cleaning of the sieve cloth. The process is referred to as ‘Salsnes filtration’ throughout the text. Salsnes filtration can point out particularly high treatment efficiency, but it is not fully understood how this is obtained. Furthermore it is not clear how the process should be operated to achieve ‘optimum performance’. In an attempt to understand this, both a theoretical and an experimental approach have been applied; hence the paper consists of two main parts. In the theoretical part, different fouling mechanisms are described, and it is explained how these affect the hydraulic resistance of the sieve cloth and the resulting filtrate flux through it. In the experimental part, sieving under different pressure conditions has been explored. It was not succeeded in obtaining data suitable for statistical analyses, but some useful suggestions were given. Most importantly, it may not be beneficial to establish a particle cake under high pres-sure conditions since this provides low permeability. It was found that upholding of high pressure was sufficient to counteract this, but that a relatively small decrease in pressure results in a significant decrease in filtrate fluxes. It is concluded that Salsnes filtration should strive for a minimum decline in the ratio between pressure difference and hydraulic resistance in order to achieve the most uni-form flux through the belt sieve, which is thought to ensure the highest treatment efficiency.
ENSURING DISTRIBUTED ACCOUNTABILITY FOR DATA SHARING IN THE CLOUD

Cloud computing is present a new Technology to Share Data or IT Based Service over the internet. Cloud Service provider are basically used to handle data to the unknown type of resources [1]. for sharing of data over the cloud also used more entities. Those entities are relevant with each other in the cloud. Also cloud computing technology is provided a approach of Dynamic data handling . But overcome to this method sharing of data over the cloud is complex process. So that for the solution of this we are use the new framework know as (CIA)Cloud Information Accountability[3]. In the cloud Information Accountability, if any user are subscribe this type of service, then service provider should provide the Access control or rights. By using the Mechanism of Access control whole information will be stored in the service provider.CIA also consists of two measure part logger and log harmonizer. JARs are used to create the Dynamic object. Ensure to this if any user should Access such data or information it will automatically logging or Authentication to JARs [4].
Evaluación de validez convergente y discriminante en tests computarizados de toma de decisiones

– Assessment of convergent and discriminant validity in computerized decision-making tests The objective of this study was to analyze the convergent and discriminant validity between impulsivity, executive functioning, and decision-making (DM) tests with and without emotional component and and agent centered DM. Through an Instrumental design, 217 participants were evaluated, 64.5% women, between 18 and 30 years of age (M=23.22 ± 2.44). The Principal Component Analysis showed four components that explained 83.88% of variance and grouped the tests as expected. In addition, the correlation study shows that the true DM tests were poorly correlated, suggesting partial convergence between them. No significant correlations were found between true DM testing and DM testing with agent focus, executive function and impulsivity. The results coincide with expectations and previous studies on the subject.

On-Farm Co-Digestion of Food Waste with Dairy Manure

Sustainable management of biowastes is currently a major concern in the United States. As of 2007, the United States had over 1 million livestock and poultry operations, 6.6% of which were dairy facilities 69,890 dairy farms (US NASS, 2009). A variety of methods are used to collect, store, and treat manure. As concerns over water quality and other environmental factors increase, improved methods for manure treatment, including anaerobic digestion, are being utilized.
Irreversible mass loss of Canadian Arctic Archipelago glaciers

The Canadian Arctic Archipelago (CAA) contains the largest volume of glacier ice on Earth outside of Antarctica and Greenland. In the absence of significant calving, CAA glacier mass balance is governed by the difference between surface snow accumulation and meltwater runoff—surface mass balance. Here we use a coupled atmosphere/snow model to simulate present‐day and 21st century CAA glacier surface mass balance. Through comparison with Gravity Recovery and Climate Experiment mass anomalies and in situ observations, we show that the model is capable of representing present‐day CAA glacier mass loss, as well as the dynamics of the seasonal snow cover on the CAA tundra. Next, we force this model until 2100 with a moderate climate warming scenario (AR5 RCP4.5). We show that enhanced meltwater runoff from CAA glaciers is not sufficiently compensated by increased snowfall. Extrapolation of these results toward an AR5 multimodel ensemble results in sustained 21st century CAA glacier mass loss in the vast majority (>99%) of the ~7000 temperature realizations.
Detection of Masquerade Attacks using Data-Driven Semi-Global Alignment Approach

The broad utilization of virtualization in representing security basis conveys unrivaled security worries for inhabitants or clients and presents an extra layer that itself must be totally arranged and secured. Gatecrashers can abuse the extensive measure of assets for their attacks. This venture talks about two methodologies . In the initial three elements to be specific continuous attacks, autonomic counteractive action activities and hazard measure are incorporated to our Autonomic Intrusion Detection Framework (AIDF) as the majority of the present security advancements don't give the fundamental security components to frameworks, for example, early notices about future progressing attacks, autonomic avoidance activities and hazard measure. Accordingly, the controller can take proactive restorative activities before the attacks represent a genuine security hazard to the framework. In another Attack Sequence Detection (ASD) approach as assignments from various clients might be performed on a similar machine. In this way, one essential security concern is whether client information is secure in. Then again, programmer may encourage processing to dispatch bigger scope of attack. For example, a demand of port output in with numerous virtual machines executing such vindictive activity. In, for instance, avoiding a simple to adventure machine and afterward utilizing the past traded off to attack the objective. Such attack plan might be stealthy or inside the registering condition. So intrusion detection framework or firewall experiences issues to recognize it.
Genome-wide associations of immune-associated traits in dairy cows

Previous work by our group has consistently identified relationships between immuneassociated (IA) traits and dairy cow health, fertility and productivity. Furthermore, we observed that these associations are partly under genetic control. SNP genotype data relating to 548 Holstein-Friesian dairy cows were used to carry out a genome-wide association study of IA traits previously linked to production, health and fertility. In this study, we discovered 96 SNPs that were significantly associated with defined IA traits, most notably SNP on chromosome 17 and natural antibodies in a region previously linked with ptosis, intellectual disability, retarded growth and mortality (PIRM) syndrome in cattle. Moreover, 22 SNP were found to be common across 2 to 3 IA traits. A functional cluster analysis was carried out on significant SNPs and showed 9 clusters of genes linked to various immune response and inflammation genes as well as significant associations with biological pathways such as systemic lupus erythematosus and metabolic processes. Results from the present study have highlighted potentially useful SNPs for inclusion in future animal breeding programs.
Occupational health problems and role of ergonomics in information technology professionals in national capital region

A cross sectional study was done among 200 Information Technology (IT) professionals in the National Capital Region (NCR) to study the computer related health problems and role of ergonomic factors. The computer related morbidity was present in 93% of the study subjects. The visual problems were seen in 76% and musculoskeletal in 77.5% while 35% felt stressful symptoms. The study subjects having inadequate lighting and not using an antiglare had greater visual problem, i.e. 81.3 and 76.3%, respectively. Of the 152 subjects that had visual discomfort, 80.2% did not have the monitor at correct distance. This observation was found to be statistically significant (P<0.05). The musculoskeletal problems were also higher in the study subjects using inappropriate ergonomics. The study has brought forth a very high prevalence of computer related morbidity among IT professionals and it further concluded that all aspects of ergonomic variables appear to be acting in cohesion in relation to computer related heath.
Comparative Performance Evaluation of TCP with Identical and Cross-Variant Congestion Control

The Transmission Control Protocol (TCP), a key functional building block of the Internet, operates as a rate-adaptive end-to-end protocol at the Transport Layer of the network protocol stack. It regulates the prevailing load conditions within the network by getting the source node to adapt the packet transfer rate in accord with the processing capacity of the receiver. The regulation is enforced by means of dropping of packets on the part of the receiver. The TCP sender then reduces the packet injection rate so as to allow the network to recover from congestion. The focus of this paper is performance evaluation of certain notable TCP congestion avoidance algorithms, namely, Vegas, Reno and New Reno. Specifically, a number of performance measures have been analysed based on ns-2 simulation data where the scenarios involved TCP flows operating with identical and cross-variant congestion control mechanisms. Congestion window behaviour, packet loss, throughput, transmission delay and jitter are the performance criteria studied with the setup mentioned. In the flows with identical variants, Vegas outperforms other TCP variants. However, TCP Vegas has been observed to contribute to unfair appropriation of the resources in the cross-variant setting.
Numerical simulation of the sound radiated from a turbulent vortex ring

The acoustic field radiated by a turbulent vortex ring is studied. Direct Numerical Simulations (DNS) of the fully compressible, three-dimensional Navier-Stokes equations are used to generate an axisymmetric vortex ring to which 3D stochastic disturbances are added. The disturbances cause instability and turbulent transition of the vortex ring. Detailed information about temporal evolution of sound pressure level, spectrum and directivity associated with modes of oscillation and their turbulent breakdown are investigated. The peak frequency agrees well with experiments, and the modal directivities agree well with predictions of vortex sound theory. Based on the selfsimilar decay of the turbulent near field, the self-similar decay of the sound field is investigated. We also explore the connections with jet noise by modeling the jet as a de-correlated train of vortex rings.

Transgene Delivery via Microelectromechanical Systems

Transgene Delivery via Microelectromechanical Systems Aubrey M. Wilson Department of Microbiology and Molecular Biology, BYU Master of Science The invention of pronuclear microinjection initiated the field of transgenic research. Over 30 years later microinjection remains the most straight-forward and most commonly used transgene delivery option. In this work we address the current progress of microelectromechanical systems (MEMS) used as transgenic delivery mechanisms. The nanoinjector is a specially designed MEMS device which uses electrostatic charge to manipulate transgene molecules. The process of nanoinjection was designed as an alternative to microinjection which causes less damage to developing embryos, improves embryo survival, birth rates, and overall efficiency of injections. In vivo testing of nanoinjection demonstrates it is both safe and effective. Additionally nanoinjection has the potential to make transgenesis via yeast artificial chromosomes more practical as the nanoinjector may prevent shearing of the YAC molecules. A second nanoinjection protocol termed intracellular electroporetic nanoinjcetion (IEN) was designed to allow for cytoplasmic injections. Cytoplasmic injections are faster and easier than pronuclear injection and do not require the pronuclei to be visible; yet previous attempts to develop cytoplasmic injection have met with limited success. In IEN injections the nanoinjector is used to place transgenic molecules in the cytoplasm. The transgenes are then propelled through the cytoplasm and electroporated into the pronucleus using electrical pulses. Electroporation of whole embryos has not resulted in transgenic animals, but the MEMS device allows localized electroporation to occur within the cytoplasm, giving transgene access to the pronucleus before degradation can occur. In this report we describe the principles which allow for localized electroporation of the pronuclei including: the location of the pronuclei between 2128 hours post-hCG treatment, modeling data predicting the voltages needed for localized electroporation of pronuclei, and data on the movement of transgenic DNA based on the voltages delivered by IEN. We further report results of an IEN versus microinjection comparative study in which IEN produced transgenic pups with viability, transgene integration, and expression rates statistically comparable to microinjection. The ability to perform injections without visualizing or puncturing the pronuclei will widely benefit transgenic research, and will be particularly advantageous for the production of transgenic animals with embryos exhibiting reduced pronuclear visibility.
SQUID SAY IT WITH SKIN: A GRAPHIC MODEL FOR SKIN DISPLAYS IN CARIBBEAN REEF SQUID (SEPIOTEUTHIS SEPIOIDEA)

The aim of this paper is to describe the construction and use of a graphic model to express ‘squiddish’, visual skin displays in reef squid Sepioteuthis sepioidea. It was created and refined as a result of a field study off the Caribbean island, Bonaire, to systematize the repertoire of this species’ patterns for an ethogram. Squid communication is composed of visual units and components on their body and postures. The color components and reflective units can be turned on and off and are grouped together for complex inter- and intraspecific communication. Like squid skin patterns, our graphic model is composed of components. It was created in Adobe PhotoShop ® and consists of a dorsal and a lateral view of a squid. These two shapes can be filled with components for displays and changes of posture by turning combinations of multiple layers in the PhotoShop program on and off. Components are divided into basic background colors and areas of the body on which they overlay distinct patterns. This model demonstrates an assortment of intraspecific displays of S. sepioidea, including variations in patterns between males and females and across different age groups, as well as interspecific displays such as camouflage patterns. It will be made publicly available via CephBase (www.cephbase.utmb.edu) to help researchers catalog the full range of displays of S. sepioidea and can also establish consistent terminology for the displays and their components of these squid.
