Mechanism of Action of Bacterial Transcription Terminator Rho

The bacterial transcription terminator, Rho, is a well conserved protein among the prokaryotes. It was discovered about 50 years back and still, a significant number of the researchers across the globe are actively engaged in understanding the function of this protein. Rho is a hexameric RNA-dependent helicase that dislodges transcribing RNA polymerase. Its binding site on the RNA is quite degenerated, and thereby many mRNAs are its target, which leads to regulation of a wide range of operons by the Rho-dependent termination. This genome-wide control by Rho brings in pleotropic effects in the cell physiology, and hence if this termination process is perturbed, many biological processes get directly affected. In this review, we will cover various mechanistic aspects of the Rho-dependent transcription termination highlighting the significant contributions made by us over the last 12 years. We shall also describe some aspects of the cell physiology that is under the control of this factor-dependent termination process. The review includes the biochemistry and the structural analyses of the Rho, its mechanism of action, its regulation by other cellular factors and briefly cellular events controlled by this protein.

Pathological effects of Meloidogyne incognita eggs on growth of sugarbeet and nematode reproduction under greenhouse conditions

The impact of three levels of Meloidogyne incognita eggs, that is, 1000, 2000 and 3000 eggs/ plant on plant growth parameters of sugarbeet cv. Nejma and its development and reproduction under greenhouse conditions at 17 ± 5°C was studied. Results indicated that reduction percentage of sugarbeet growth parameters were greatly affected, where the marginal effect was more pronounced on roots than shoots. Moreover, as the inoculation level increased from 1000 up to 3000 eggs of M. incognita /plant, the percentage reduction of plant growth parameters increased, where the highest values were recorded to be 48.97 and 24.18% by 3000 eggs/ plant for shoot dry and whole plant fresh weights, whereas, their lowest values of 30.93 and 4.05% resulted by inoculation level of 1000 eggs/ plant for the same plant growth criteria, respectively. Moreover, the highest rate of nematode reproduction on sugarbeet plants cv. Nejma was recorded by the level of 2000 eggs per plant with value of 1.05 whereas the lowest ones of the same criterion resulted by the levels of 3000 or 1000 eggs per plant that were 0.85 or 0.84, respectively. M. incognita infection to sugar beet plants cv. Nejma at the three levels of egg inoculation obviously reduced N, P, K and total chlorophyll content on leaves of sugarbeet with values of 9.9% (N), 18.5% (P), 8.8% (K), 1.58% (chlorophyll) and 20.0% (N), 27.4% (P), 18.4% (K) and 5.9% (chlorophyll) by 1000 and 3000 eggs/ plant, respectively compared to the uninoculated plant. Key words: Meloidogyne incognita, sugarbeet, inoculum levels.
Inverse Edelstein effect induced by magnon-phonon coupling

We demonstrate a spin to charge current conversion via magnon-phonon coupling and an inverse Edelstein effect on the hybrid device ${\mathrm{Ni}/\mathrm{Cu}(\mathrm{Ag})/\mathrm{Bi}}_{2}{\mathrm{O}}_{3}$. The generation of spin current $({J}_{s}\ensuremath{\approx}{10}^{8}\phantom{\rule{0.28em}{0ex}}\text{A}/{\text{m}}^{2})$ due to magnon-phonon coupling reveals the viability of acoustic spin pumping as a mechanism for the development of spintronic devices. A full in-plane magnetic field angle dependence of the power absorption and a combination of longitudinal and transverse voltage detection reveals the symmetric and asymmetric components of the inverse Edelstein effect voltage induced by Rayleigh-type surface acoustic waves. While the symmetric components are well studied, asymmetric components still need to be explored. We assign the asymmetric contributions to the interference between longitudinal and shear waves and an anisotropic charge distribution in our hybrid device.
In vitro testing of substances derived from tropical plants as possible drugs against Entamoeba histolytica and Giardia intestinalis

Die parasitischen Protozoen Entamoeba histolytica und Giardia intestinalis sind weltweit verbreitete Krankheitserreger. E. histolytica verursacht Amobenruhr und Leberabzess mit etwa 40 Millionen Infizierten pro Jahr und bis zu 100.000 Todesfallen. G. intestinalis verursacht jedes Jahr etwa 280 Millionen symptomatische Infektionen und eine hohe Morbiditat unter Kindern mit chronischem Durchfall. Seit uber 40 Jahren ist Metronidazol das Therapeutikum der Wahl zur Behandlung der beiden Parasiten. Allerdings hat dieses Medikament auch unerwunschte Eigenschaften wie zum Beispiel mogliche Teratogenitat und Neurotoxizitat. Das Ziel dieser Arbeit war es, die Aktivitat von vierzehn neu isolierten Naturstoffen gegen E. histolytica und G. intestinalis zu testen, die aus tropischen Pflanzen der Familien Rutaceae, Meliaceae und Stemonaceae isoliert waren. Die Parasiten wurden in 96-Loch Mikrotiterplatten in luftdichten Plastikboxen unter anaeroben Bedingungen gezuchtet. Jede Substanz wurde zuerst in Schnelltests in den Konzentrationen von 1 µg/ml und 20 µg/ml getestet. Lebende und tote Zellen wurden nach 24 h und 48 h angefarbt und gezahlt. Nur eine der Substanzen zeigte eine Aktivitat gegen die beiden Parasiten, Methylgerambullin, ein Schwefel enthaltendes Amid, das aus Glycosmis mauritiana isoliert war. In zusatzlichen Tests wurde zum Beispiel eine EC50 von 6,09 µg/ml fur anti-Amoben und 6,14 µg/ml fur anti-Giardien Aktivitat fur eine Behandlung von 24 h gefunden. Die Aktivitat des Methylgerambullins war in frischem Medium niedriger und wir vermuteten, dass dieser Effekt mit dem Gehalt von reduziertem Cystein in Medium zusammenhing. Deshalb konnte die chemische Reaktion zwischen Methylgerambullin und Thiolgruppen im Medium und in den Parasiten wichtig fur den Wirkmechanismus sein. Der Effekt des Methylgerambullins auf das E. histolytica Proteom wurde mittels zweidimensionaler Gelelektrophorese analysiert. Vier neue Spots in den behandelten Amoben wurden mittels Tandem-Massenspektrometrie als Isoformen von Alkoholdehydrogenase und Pyruvat:Ferredoxin Oxidoreduktase identifiziert. Beide Proteine waren in dem Gel zu einem saureren isoelektrischen Punkt verschoben, moglicherweise wegen Phosphorylierungen. Zusammenfassend wurde in dieser Arbeit eine neue aktive Substanz identifiziert und erste Informationen uber ihren Wirkmechanismus wurden gewonnen.
Dynamical Theory of Crystal Lattices

Although Born and Huang's classic work on the dynamics of crystal lattices was published over thirty years ago, the book remains the definitive treatment of the subject. It begins with a brief introduction to atomic forces, lattice vibrations and elasticity, and then breaks off into four sections. The first section deals with the general statistical mechanics of ideal lattices, leading to the electric polarizability and to the scattering of light. The second section deals with the properties of long lattice waves, the third with thermal properties, and the fourth with optical properties.
Aalborg Universitet Feature extraction and classification for Brain-Computer Interfaces

In this Thesis three neurological phenomena are investigated and used in two di erent BrainComputer Interface (BCI) systems. These neurological phenomena are Steady-State Visual Evoked Potentials and the electroencephalographic patterns produced by auditory and spatial navigation imagery. In the rst chapter the aims and description of the Thesis are included. The second chapter is composed of a review of the relevant literature, and a description of relevant technologies (bio-recording and signal processing) and neurological phenomena, used to drive BCI systems. Chapter 3 is a description of a matlab toolbox for analysis and design of BCI systems, which was developed for the studies in Chapters 4 , 5 and 6. Chapter 4 is a technical report which describes a BCI system based on SS-VEP and its application on augmentative communication and mobilization. Chapters 5 and 6 explore di erent approaches to feature extraction, selection and classi cation methods for a BCI system based on Auditory and Spatial Navigation Imagery. The MATLAB toolbox described in Chapter 3 was used for the development of the online BCI system based on SS-VEP described in Chapter 4, which can produce 9 di erent command signals. This system was tested on healthy subjects and showed a classi cation accuracy of 79.74 % (57-100 %) with an Information Transfer rate of 21 bits/min. The manuscript in Chapter 5 assesses three approaches to feature extraction for a BCI driven by non-motor imagery. The tasks studied in this paper were auditory and spatial navigation imagery which were recorded from 19 naïve subjects. The results of this study show that features extracted using an optimization procedure for the Discrete Wavelet Transform (DWT) produce higher classi cation rates than those obtained by features extracted with common DWT analysis and autoregressive (AR) modeling. The average classi cation accuracy using the optimization procedure for the DWT was 70.1 % (63.3-83.3 %). The study in Chapter 6 investigates two methods for classi cation of auditory and spatial navigation imagery: Bayesian classi er and support vector machine. Features were extracted using AR modeling and optimized DWT and selected with exhaustive search, from the combination of 2 and 3 channels, and with a discriminative measure (r2). The results showed that both classi ers provided similar classi cation accuracies. Conversely, the exhaustive search of the optimal combination of features from 2 and 3 channels signi cantly improved the performance with respect to using r2 for channel selection. Using features optimally extracted from 3 channels with optimized DWT, the classi cation accuracy was 72.2 % (64.7-91.5%).
OSMOS , a spatially explicit model to simulate the epidemiology of Cosmopolites ordidus in banana fields

A stochastic individual-based model called COSMOS was developed to simulate the epidemiology of banana weevil Cosmopolites sordidus, a major pest of banana fields. The model is based on simple rules of local movement of adults, egg laying of females, development and mortality, and infestation of larvae inside the banana plants. The biological parameters were estimated from the literature, and the model was validated at the small-plot scale. Simulated and observed distributions of attacks were similar except for five plots out of 18, using a Kolmogorov–Smirnov test. These exceptions may be explained by variation
Downwelling wind, tides, and estuarine plume dynamics

The estuarine plume dynamics under a downwelling-favorable wind condition were examined in the windy dry season of the Pearl River Estuary (PRE) using the PRE primitive-equation Finite-Volume Community Ocean Model (FVCOM). The wind and tide-driven estuarine circulation had a significant influence on the plume dynamics on both local and remote scales. Specifically, the local effect of downwelling-favorable winds on the plume was similar to the theoretical descriptions of coastal plumes, narrowing the plume width, and setting up a vertically uniform downstream current at the plume edge. Tides tended to reduce these plume responses through local turbulent mixing and advection from upstream regions, resulting in an adjustment of the isohalines in the plume and a weakening of the vertically uniform downstream current. The remote effect of downwelling-favorable winds on the plume was due to the wind-induced estuarine sea surface height (SSH), which strengthened the estuarine circulation and enhanced the plume transport accordingly. Associated with these processes, tide-induced mixing tended to weaken the SSH gradient and thus the estuarine circulation over a remote influence scale. Overall, the typical features of downwelling-favorable wind-driven estuarine plumes revealed in this study enhanced our understanding of the estuarine plume dynamics under downwelling-favorable wind conditions.
Linguistics and Behaviour Analysis in the Functional Conceptualization of Verbal Irony

espanolEl objetivo de este estudio es identificar el concepto de ironia como se expresa en el libro 1957 por BF Skinner, Comportamiento Verbal, y para aumentarla con las definiciones de la ironia que figuran en el 1961 el trabajo por MHN Paiva, Contribucion a una ironia estilistica. Concepto de la ironia de Skinner fue interpretado usando hermeneutica del comportamiento. El trabajo de Skinner y de Paiva se complementan entre si; concepto de la ironia de Skinner se fusiono con la definicion de Paiva de ironia. El resultado muestra que Skinner's ironia puede ser conceptualizada como una conducta verbal bajo control multiple de los estimulos y las operaciones de motivacion y dirigido a multiples audiencias con diferentes funciones. Paiva contribuye mediante la diferenciacion de los cinco tipos de ironia y las atmosferas que pueden indicar diferentes e importantes funciones de la burla que la ironia genera. La conclusion es que este apego contribuye al analisis funcional de la ironia verbal y puede senalar donde, como y por que (por que) este comportamiento se emite en relacion con las diversas facetas de la burla. EnglishThe aim of this study is to identify the concept of irony as expressed in the 1957 book by B.F. Skinner, Verbal Behaviour, and to enlarge it with the definitions of irony contained in the 1961 work by M.H. N. Paiva, Contribution to a Stylistic Irony. Skinner’s concept of irony was interpreted using behavioural hermeneutics. Skinner's and Paiva's work complement each other; Skinner’s concept of irony was merged into Paiva's definition of irony. The result shows that Skinner´s irony can be conceptualized as a verbal behaviour under multiple control from stimuli and motivational operations and directed to multiple audiences with different functions. Paiva contributes by differentiating the five types of irony and the atmospheres that can indicate different and important functions of the ridicule that the irony generates. The conclusion is that this attachment contributes to the functional analysis of verbal irony and can point to where, how and why (for what) this behaviour is emitted with respect to the various facets of ridicule
Transfers and transition: The impact of government support on factor demand and production in Eastern Germany

The paper presents an error-correction model of factor demand and output, analysing the effects of a change in relative factor prices on investment, employment and output in the eastern German manufacturing sector. The principal aim is twofold: first, to examine if the large amounts of capital subsidization mainly benefitted the capital-intensive industries, thus leading to distortions in the production structure, and second, to find out if the subsidies proved to be successful in creating employment in the eastern German industries or if they rather contributed to a substitution of capital for labour and skilled labour. The model uses the concept of the user cost of capital for a representation of capital costs, integrating the main instruments of subsidization. The results confirm that all in all, capital subsidies seem to encourage capital-intensive production structures. As to employment, the positive output effect might overcompensate the substitution effect only for skilled, but not for unskilled labour and only in the capital- and surprisingly also in the labour-intensive industries. For the skilledlabour- intensive industries, the outcome is much less encouraging.
Robot Secured Wireless Authentication Using Look-Up Table Based Coding

Securing restricted areas is a major concern for sensitive institutes, like military or research labs. Most security measures rely on having some of the biometrics that human beings possess to identify the user and grant access permissions. Yet, with the wide spread of robotic systems and avatars, these entities need to be authenticated as well, since they might require access to such facilities, hence, the need to provide security measures that can handle non-biological entities with high levels of security and that is not vulnerable to hacking is becoming essential.In this research we propose a novel and unique system for encoding the passcode that is known only to the authorized user using a specially designed look-up table. The system’s hardware requires reconfiguring doors’ security modules to have Near Field Communication (NFC) initialized inside them, and have the Robot initialized with the same hardware, and a wireless controller for the NFC will be given to the operator. The hardware has low-cost, and is easy to use since it is considered as plug and play module. XBEE was adopted as a wireless communication module between the operator and the robot in order to wirelessly connect to an NFC chip that is installed (as plug and play) on any Robotic system.
STANDING PROPHECY BASED ON PUBLIC REACTION FROM TEXTUAL REVIEWS

We concentrate on the rating conjecture task. However, user’s rating star-level information isn't necessarily on just about all review websites. Hence, the easiest method to mine reviews along with relation between reviewers in social systems is becoming an essential issue in web mining, machine learning and natural language processing. According to users’ sentiment, we are feeling when two products have similar sentiment distribution, they've similar status, plus they could be printed using the same ratings. Sentiment analysis is known as because the fundamental and important operate in removing user’s interest preferences. To get the status inside the product, sentiment in reviews is essential. Normally, if item’s reviews reflect positive sentiment, the product might be with greater status obtaining a certain amount. Within our work, we utilize social users’ sentiment to infer ratings. we extract product features from studying reading user reviews. Then, everybody knows the sentiment words, which are broadly-knowledgeable about describe the merchandise features. However, some websites don't always offer structured information, additionally to they do not leverage users’ unstructured information. Experts to uncover both novel and relevant recommendations. By analyzing the client ratings, they might recommend special experts obtaining a target user when using the user population. We mainly would like to get the merchandise features including some named entities plus numerous product/item/service attributes. LDA is a Bayesian model that's experienced in model the writing of reviews, topics and words. we conduct numerous experiments to judge the performance inside our rating conjecture model according to user sentiment. We compare the performance inside our method while using the existing models on Yelp dataset.
Distributed Malware Detection Algorithm (DMDA)

The increasing number of malwares has led to an increase in research work on malware analysis studying the malware behavior. The malware tries to leak sensitive information from infected devices. In this paper, we study a specific attack method, which distributes the data source and the point of data loss on different versions of the malware application. That is done using local storage by storing part or all of the vital data to be leaked in the future. We introduce a Distributed Malware Detection Algorithm (DMDA), which is an algorithm to detect distributed malware on app versions. DMDA proposes a new way to analyze application against redistributed malware. DMDA is created to analyze the data and identify transitional loss points. We test this algorithm on a sample of Android applications published on the Google Play market containing 100 applications, where each application has two versions. The algorithm detected 150 transient data sources, 200 transient loss of data point and two leakages of data. In comparison, this dataset was checked using 56 anti-malware applications but none of them could find any malicious code.
Production of Poly(3-Hydroxybutyrate-Co-3-Hydroxyvalerate) by Marine Archaea Haloferax mediterranei Dsm 1411 with Yeast Extract As Nutrient Source

In many countries, most of household goods are made from polymer or plastic. The polymer manufacturing industry has been relying on fossil fuel-based raw materials which are non-biodegradable. Plastics derived from these non-biodegradable sources will be difficult to degrade in nature, which in turn will pollute the environment and harm the ecosystem. One way to reduce the ecosystem damages caused by petroleum-based plastic is by using biodegradable materials for plastic industry, such as Polyhydroxyalkanoates (PHA). Poly (3-hydroxybutyrate-co-3-hydroxyvalerate) or PHBV is an example of PHA that can be produced by several types of microorganism, one of them is marine archaea Haloferax mediterranei. The objective of this study is to determine the productivity of marine archaea H. mediterranei cultures to produce PHBV with yeast extract as main nutrient sources. Experiments and analysis were conducted in triplicate and batch operating system. During the fermentation process, optical density, glucose levels, phosphorus levels, pH, and dry cell weight (DCW) were observed. The final product was then analysed using GC-MS to determine 3HB (3-hydroxybutyrate) and 3HV (3-hydroxyvalerate) fraction composition in the PHBV. The results showed that the maximum specific growth rate (m) and doubling time (Td) of the H. mediterranei were 0.1258 hours-1 and 5.51 hours, respectively. H. mediterranei biomass increased until it reached stationary phase after 95 hours incubation. The PHBV content, dry biomass and yield of PHBV to substrate were 2.62 g/L, 29.1% and 0.27 g/g, respectively.
Studies on the fatty acid profile in Hilsa and plankton in Hooghly -estuarine system of West Bengal, India

Hooghly-estuarine system of West Bengal is one of the most important riverine system of India. One of the important commercial fish yields from this riverine system is Hilsa Tenualosa ilisha. The normal habitat of the fish is the lower region of the estuaries and the for eshore areas of the sea. It ascends the rivers mainly for spawning and spent fish as well as their progeny migrate down the rivers towards lower estuaries and coastal areas, which form the natural habitat of the species. During migration its body compositi on changes specially in terms of fatty acid profile. This fish has high content of ω3 fatty acid which has various beneficial properties for the normal human body like anti inflammatory, antithrombotic, hypolipodermic and vasodialatory properties. The lipid content of the hilsa body was found between 1.66 to 13.11%. The fish contains higher amount of polyunsaturated fatty acids. ω3 value varied between 6.6% to 15.1% of the total lipid content in the hilsa body. ω6 fatty acid was another important constituent of the fish body and the value varied from 2.35 to 3.65 % of the total lipid content in the fish body. In this respect hilsa is an important diet. The source of PUFA in fish body is plankton. The fish gut analysis shows the same type of plankton availability as in the water. Moreover, positive correlation found in the values of fatty acids of river plankton and hilsa gut. Same type of fluctuation was also found in river water plankton and hilsa body with seaso nal changes. In the plankton body ω3 value was found to be 16.57% to 25.75% and ω6 value was 6.71% to 12.6% of the total plankton lipid content.
