Influence of local exhaust ventilation parameters on the quality of the room’s air environment

The article considers the influence of local exhaust ventilation parameters on the quality of the room’s air environment. On the basis of experimental studies, dependencies were established that determine the effect of mass transfer processes occurring in the local exhaust ventilation shelter on air quality in a room working area. The influence of a flat plate installed in the lower part of technological opening of a shelter that prevents incoming air movement from a room to a source surface of convective jet is determined. This measure made it possible to reduce the air velocity above surface source and the amount of harmful emissions by 2.5 times, as well as to reduce their flow into a room through an opening a shelter. These measures allow to reduce energy costs for room ventilation and improve air quality in the serviced room.
Assessing molluscs functional diversity within different coastal habitats of marine protected areas

Molluscs assemblages inhabiting subtidal habitats (sandy bottoms, photophilic and sciaphilic hard bottoms, Posidonia oceanica seagrass beds) represent a valuable part of coastal biodiversity and were studied in four Italian Marine Protected Areas. Quantitative samplings were carried out in late spring - summer of 2015. A total of 776 individuals were identified, belonging to the classes of Polyplacophora (5 species, 24 individuals), Gastropoda (62 sp., 240 ind.), Bivalvia (51 sp., 488 ind.), and Scaphopoda (3 sp., 24 ind.). Multivariate analyses revealed significant inter-habitat differences in the composition of mollusc assemblages, especially between soft bottom and all the other habitats. In all MPAs, the highest species richness and feeding guilds occurred in the photophilic hard bottom, where, in contrast, a lower number of individuals was found. On the contrary, in the soft bottom the highest number of individuals and the lower species richness and feeding guilds were found. Although the results pointed out some intra-habitat differences among MPAs, the molluscan assemblages showed a valuable degree of taxonomic and trophic similarity, especially in vegetated habitats. These results are of primary importance for ecosystem functioning and management as the considered habitats are the most relevant of the coastal zones.
Site-Specific DNA Demethylation as a Potential Target for Cancer Epigenetic Therapy

Aberrant promoter DNA hypermethylation is a typical characteristic of cancer and it is often seen in malignancies. Recent studies showed that regulatory cis-elements found up-stream of many tumor suppressor gene promoter CpG island (CGI) attract DNA methyltransferases (DNMT) that hypermethylates and silence the genes. As epigenetic alterations are potentially reversible, they make attractive targets for therapeutic intervention. The currently used decitabine (DAC) and azacitidine (AZA) are DNMT inhibitors that follow the passive demethylation pathway. However, they lead to genome-wide demethylation of CpGs in cells, which makes difficult to use it for causal effect analysis and treatment of specific epimutations. Demethylation through specific demethylase enzymes is thus critical for epigenetic resetting of silenced genes and modified chromatins. Yet DNA-binding factors likely play a major role to guide the candidate demethylase enzymes upon its fusion. Before the advent of clustered regulatory interspaced short palindromic repeats (CRISPR), both zinc finger proteins (ZNFs) and transcription activator-like effector protein (TALEs) were used as binding platforms for ten-eleven translocation (TET) enzymes and both systems were able to induce transcription at targeted loci in an in vitro as well as in vivo model. Consequently, the development of site-specific and active demethylation molecular trackers becomes more than hypothetical to makes a big difference in the treatment of cancer in the future. This review is thus to recap the novel albeit distinct studies on the potential use of site-specific demethylation for the development of epigenetic based cancer therapy.
Comparative morphological analysis during larval development of three syntopic newt species (Urodela: Salamandridae)

Abstract We provide comparative and updated staging tables for the larvae of three syntopic newt species – Triturus carnifex, Lissotriton italicus and Ichthyosaura alpestris inexpectatus –living in Calabria. A detailed description, stage by stage, of the full larval period until completion of metamorphosis is furnished, accompanied by photographic tables of the most important stages. The appearance of the most prominent and easily identifiable morphological features (i.e. development of gills, balancers and limbs; and body pigmentation), and length, have been used as staging criteria. Ontogenic development in the three considered species is compared with that of other Caudata species. For the three newt species, we also performed a comparative analysis of the developmental larval phases, emphasising the shared and species-specific features. The present descriptive study adds comparative information on distinctive morphological traits that may be useful for the recognition of newts during larval ontogeny and, in some cases, when sampling in the field.
The oceans around southern Africa and regional effects of global change : START Regional Syntheses

In the last few decades, a great deal of work has been carried out on the nature of the oceanic circulation around southern Africa. Attempts have been made to determine regional ocean-atmosphere interactions and the effect of changing sea-surface temperature fields on weather and climate. At the same time, the marine biology and ecosystems of coastal waters have been extensively studied. Few studies have been concerned with the possible effects of global change on the physical and biological components of the systems and their linkages in the regional earth system of the subcontinent. In this paper, a first attempt is made to integrate past work and synthesize it using a systems approach framework. Attention is focused on the nature of the regional ocean circulations affecting southern Africa. The features of the Agulhas and Benguela systems most likely to be affected by global change are discussed and contrasted. At the same time the links to the marine biological and coastal ecosystems of the east and west coasts are explored and the inter-dependencies between physical, biogeochemical and ecological components of regional ocean systems and their anthropogenic modulation are considered.
DO RIO À MESA, O CONSUMO DE PESCADOS NA AMAZÔNIA: PERFIL DO CONSUMIDOR E CRITÉRIOS DE COMPRA EM BELÉM (PA)

Several initiatives have promoted campaigns aimed at increasing fish consumption in Brazil, given the benefits of the nutritional components of this type of food. However, it is essential that, at the time of purchase, several aspects are taken into account to ensure that the fish are in conditions suitable for consumption. Therefore, this work aimed to identify the profile and the criteria for the purchase and consumption of fish by consumers who attended the Municipal Market in the District of Icoaraci, Belém (PA), to investigate not only the regularity of consumption, but also the quality parameters adopted in the purchase of the fish. To this end, bibliographic, documentary and field research were carried out. The data collection was established from the application of a questionnaire, with 25 semi-structured questions about socio-economic aspects and criteria such as color, flavor and texture of fish, as well as the frequency and forms of consumption, with 120 consumers. The results revealed that there is a concern to acquire and consume good quality food, but the financial condition, the forms of supply and the low cost of the products make the adoption of such care unfeasible.
Relation structure-propriétés dans les bicouches gonflées de phases lamellaires

Les bicouches de tensioactifs sont des modeles de membranes cellulaires. La constante de rigidite  determine la forme de l'assemblage des membranes ou des processus comme la fusion de membranes, l'adherence de proteine. Nous avons etudie l'evolution de la constante de rigidite d'une bicouche de tensioactifs non ioniques (CiEj) en phase lamellaire en fonction de ses parametres structuraux. Dans une approche experimentale, nous avons montre que  diminue avec l'aire ou la longueur de la tete polaire, et qu'elle augmente avec la longueur de chaine aliphatique a aire par molecule de tensioactif constante. Nos travaux ont mis en evidence le couplage des monocouches en phase ternaire CiEj- eau-dodecane et le role determinant de la conformation des CiEj sur . L'ajout de glycerol augmente . Nous proposons deux processus pour l'expliquer. Dans une approche de dynamique moleculaire, nous avons parametre les molecules CiEj dans le champ de force GROMOS G53A6 et avons simule des bicouches de 900 tensioactifs dans l'eau sur plus de 50 ns. La constante de rigidite et les parametres structuraux sont reproduits avec un bon ordre de grandeur. Les simulations avec glycerol appuient les deux processus que nous avons proposes.
Emotion Recognition Using Three-Dimensional Feature and Convolutional Neural Network from Multichannel EEG Signals

Using electroencephalogram (EEG) signal to recognize emotional states has become a research hotspot of affective computing. Previous emotion recognition methods almost ignored the correlation and interaction among multichannel EEG signals, which may provide salient information related to emotional states. This article proposes a novel approach based on rearranged EEG features and deep learning algorithm. In particular, each channel EEG signal is first processed in time domain to get time-domain features. Then, features of all channels are treated as a three-dimensional (3D) feature matrix, according to positions of electrode sensors. This makes the features closer to the real response of the cerebral cortex. Subsequently, an advanced convolutional neural network (CNN) designed with univariate convolution layer and multivariate convolution layer is employed to deal with the 3D feature matrix for emotion recognition. A benchmark dataset for emotion analysis using physiological signal is employed to evaluate this method. The experimental results proved that the 3D feature matrix can effectively represent the emotion-related features in multichannel EEG signals and the proposed CNN can efficaciously mine the unique features of each channel and the correlation among channels for emotion recognition.
DCE-Based Secure Transmission for Massive MIMO Relay System Against Active Eavesdropper

Discriminatory channel estimation (DCE) based on two-way training can effectively enhance physical layer security in multiple-input multiple-output (MIMO) systems. In this paper, considering an active eavesdropping scenario where the eavesdropper (Eve) can adaptively switch between passive eavesdropping, and active jamming modes, we propose a new DCE-based secure transmission scheme with cooperative jamming, and artificial noise (AN) insertion in massive MIMO decode-and-forward (DF) relay systems. To characterize the performance of the proposed scheme, firstly, the closed-form expressions for normalized mean squared error (NMSE) of legitimate channels, and wiretap channels are derived. Then, according to the NMSE obtained during channel estimation phase, we design different secure transmission schemes, and derive the approximative expressions of average security rate with respect to the behavior of active Eve, including malicious jamming, and passive eavesdropping, respectively. Finally, the power allocation at source, and relay is jointly optimized to minimize the average signal to interference plus noise ratio (SINR) at the Eve while ensuring that of the legitimate receivers to be large than a threshold for the quality-of-service (QoS) requirement. Numerical results show that the proposed DCE-based secure transmission scheme can effectively discriminate the CSI between legitimate receivers, and Eve even in the presence of an active Eve, and therefore achieve a better security performance than that without DCE.
A review on plants having anti-inflammatory activity

Inflammation is a healthy process of body resulting from some disturbance or diseases. Traditional plants play a very important role in the discovery of new drugs and less adverse effects. Plants have played an important role in human health care since the ancient times. So to overcome this problem new drugs are very requisite and in plants have many of phytochemical constituents are polyphenols, lignans, anthraquinones, flavonoids, alkaloids, terpenoids, saponins, polysaccharides and peptides. Which are helpful in inflammation and have less side effects. So in this article included some herbal medicinal plants on behalf of their phytochemical constituents which can be helpful in inflammation.
Novelty and surprise-timing are broadcast by the basal forebrain

The basal forebrain (BF) is a principal source of modulation of the neocortex, and is thought to regulate cognitive functions such as attention, motivation, and learning by broadcasting information about the behavioral salience of events. An event can be salient because it is novel, surprising, or associated with reward prediction errors. But to date, the type of salience-related information the BF broadcasts is unclear. Here, we report that many BF neurons display phasic excitatory bursting that rapidly conveys the magnitude, probability, and timing of primary reinforcements. The same BF neurons also discriminate fully expected novel visual objects from familiar objects and respond to object-sequence violations, regardless of their relevance for subsequent behaviors, suggesting that they are not dedicated to signaling information about primary reinforcements. A different group of BF neurons displayed ramping activations that predicted the time of novel and surprising events. Their ramping was highly sensitive to the subjects’ confidence in event timing. Hence, BF neurons signal statistics about time and salience. Their activity may organize cortical computations to facilitate accurate behavioral responses to a diverse set of expected and ongoing events.
Control Verifications of Space Manipulators Using Ground Platforms

The article discusses dynamic requirements for designing ground manipulator platforms that can be utilized to verify the performance of controllers developed for space manipulators. Dimensional analysis is used to formalize the dynamic equivalence conditions and control scaling laws between a given space manipulator and the ground manipulator to be designed, such that the space manipulator and the designed ground manipulator are dynamically equivalent. Given that, unlike its space counterpart, the ground manipulator may not have the complete six degrees of freedom for its base and it must function under the gravity effects, as well as manufacturing imprecisions in building the ground manipulator, the sensitivity of dynamic equivalence conditions to the abovementioned factors is analyzed. Furthermore, an error compensation scheme based on the feedback linearization technique is developed to make the closed-loop ground manipulator have similar joint movements to those of the space manipulator under its controller. As a result, ground-based verification experiments can be performed for the controllers that will operate on the space manipulator. The design of a ground manipulator with the error compensation scheme for a specific space manipulator is illustrated through simulations, and it is shown how the performance of a PID controller for the space manipulator can be verified using the designed ground manipulator.
Wave energy in the UK: Current scope, challenges and prognostications

This paper reviews the current status, challenges and prognostications of wave energy systems (WES), which have momentous scope in the UK that could deliver the UK’s net zero energy target by 2050. In Britain, there are 43 primary seaside towns around the coast in which 37 are in England that encompass a collective population of 2.9 million and signify around 5.7 % of the population of England as a whole where the zero energy coastline house projects can be initiated with WES. The progress in the development of standalone WES for a vision of zero energy coastline houses is still in its initial stages. This paper exhibited a brief review of the onshore, nearshore and offshore WES technologies, particular focus was made to the scope in the UK. The feasibility and efficiency of WES study imply that the power take off (PTO) efficiency is crucially important as the overall output depends on the optimum energy harness from WES that will improve its competitive prowess with other renewable technologies and further reduce the cost of WES manufacturing. This study implicates one of prognostications that developing marine energy resources in the UK can save 60 metric tons of carbon dioxide by 2025. This study also concluded that WES can pose environmental challenges such as alterations of water column to biota and sea-bed habitats, dredging, noise and vibrations. The prognostication of zero energy coastline houses arises due to the location of the UK, which is one of the major determinants for the future success of wave energy projects, as the UK is located at the long fetch of the Atlantic Ocean and has the wind direction from the west. The available resource to harness wave energy in the UK is around 120 GW.

Tinnitus is likely related to hyperactivity in central auditory structures. In the central nervous system, activity is dependent on excitatory/inhibitory neurotransmission. Gamma-aminobutyric acid (GABA) is a major inhibitory neurotransmitter. It can activate the type-B GABAergic receptor (GABA B receptor), which can control the level of excitation/inhibition through regulating the release of neurotransmitters and lowering the …
Evaluation of the Cytogenotoxic Effects of Emulsifiable Concentrate form of Amitraz Pesticide on Allium cepa L

The cytogenotoxic effects of emulsifiable concentrate of amitraz pesticides was evaluated using Allium cepa L. test. The root meristems of A. cepa L. were treated with five concentrations (1%, 5%, 10%, 20% and 40%) of the chemical pesticide at 48 h for cytogenetic analyses and 96 h for root length inhibition. Pesticide doses affected root length significantly (P 0.05). The mean root length of the treated A. cepa for Amitraz pesticides in all concentrations was lower compared to the control showing the obvious mitodepressive effects of amitraz pesticides. A dose dependent reduction in the total mitotic dividing cells and mitotic index was observed in A. cepa treated with the pesticides. The values of mitotic index obtained for amitraz pesticides at 5% (5.20), 10% (4.0), 20% (2.30) and 40% (0.80) were lower than half of the negative control (7.25), which reflect its cytotoxicity. All the concentrations of the pesticides used in the present study induced important abnormalities during mitotic division. These aberrations were: chromosome stickiness, disturbed spindle, anaphase and telophase bridges, chromosome fragments, laggard chromosomes, and c- Mitosis. The highest abnormality number was observed in the root tips of Allium cepa (5%) while the least was at 40%. Frequencies of chromosome abnormalities were low at 20% and 40% concentration because of damaged cell and lower cell divisions. The present study, showed the inhibition of growth and induction of chromosomal aberrations by amitraz, this suggest their capability in inducing cytotoxicity and genome instability Keywords: Allium cepa , chromosomes, amitraz pesticides, aberrations, mitotic index
A circular economy approach for sustainable economic development

This paper focuses on the circular economy approach which is based on the principle of recycle of resources. It is an alternative to the existing linear economy that is based on the principle of 'take-make-dispose', which is unsustainable for economic growth due to limitation of resources in the world. This study especially set up a circular economy model for sustainable development in the frame work of endogenous economic growth incorporating waste as valuable stock for further production. The paper highlights (a) stock of waste accumulation, (b) dynamics of waste in closed-loop system and (c) economic growth path. Recycling economic activities contributes in the economic development with reuse of resources without degrading environment. This paper tangentially provides empirical support to our model for sustainable development.
Einfluss der zeitlichen Auflösung auf die raumzeitliche Segmentierung geomorphologischer Änderungsprozesse in 3D-Punktwolken

Zusammenfassung: Zeitserien von 3D-Punktwolken werden zunehmend für die Beobachtung geomorphologischer Phänomene genutzt. Dieser Beitrag untersucht, wie eine veränderte zeitliche Auflösung die raumzeitliche Abgrenzung von Oberflächenprozessen beeinflusst. Dazu wird eine Zeitserien-basierte Region Growing Segmentierung verwendet. Die Untersuchung erfolgt am Beispiel einer Sandbank an einem Strand in den Niederlanden, der über fünf Monate stündlich mit terrestrischem Laserscanning erfasst wurde. Die Ergebnisse zeigen, dass die zeitliche Prozessabgrenzung maßgeblich vom gewählten Zeitintervall abhängt. Auf Basis dieser Prozessabgrenzung kann die anschließende raumzeitliche Segmentierung auf ausgedünnten Zeitserien und somit mit reduziertem Berechnungsaufwand erfolgen.
