Postoperative Anesthesia Of Elderly And Senile Patients With Total Joint Replacement Of The Lower Extremities

Objective: To evaluate the efficacy and safety of patient-controlled analgesia through prolonged epidural analgesia after joint replacement of the lower extremities. Material and methods. We analyzed the postoperative period of 213 elderly and senile patients who were operated on for degenerative-dystrophic and traumatic injuries of the joints of the lower extremities. All patients underwent total joint replacement (164 THA and 49 TKA). The age of patients is from 65 to 90 years (average age was 78 ± 8 years) with a physical status of ASA 3 and above. All examined patients were divided into 2 groups. 63 patients comprised the main group, which in the postoperative period underwent patient-controlled analgesia (PCA) through prolonged epidural analgesia. The control group consisted of 150 patients, for the anesthesia of which in the postoperative period only standard systemic multimodal analgesia was used Conclusion. Patient-controlled analgesia is an alternative to traditional analgesic regimens. This method should be one of the main methods after surgical anesthesia for joint replacement of the lower limb in elderly and senile patients.
A Comparison between Organic and Conventional Olive Farming in Messenia, Greece

Olive farming is one of the most important occupations in Messenia, Greece. The region is considered the largest olive producer in the country and it is recognized as a Protected Designation of Origin (PDO) for Kalamata olive oil, which is considered extra fine. In response to the declining trend of organic olive farming in Greece, this study assesses to what extent organic olive farming in Messenia provides a financially and environmentally competitive alternative to conventional olive farming. In this study, 39 olive farmers (23 conventional and 16 organic) participated in interviews based on questionnaires. The results showed that organic olive farming is significantly more profitable than conventional farming, primarily because of a higher price for organic olive oil. Despite this, the majority of the conventional farmers perceived a low profit from organic farming as the main constraint to organic olive farming. All farmers agreed that organic olive farming contributed to a better environment, health and quality of olive oil. Organic farmers used fewer synthetic pesticides and fertilizers and applied more environmentally-friendly ground vegetation management techniques than conventional farmers. Overall, organic farming was found to provide a competitive and sustainable alternative to conventional olive farming in Messenia.
Iron Speciation in PM2.5 From Urban, Agriculture, and Mixed Environments in Colorado, USA

Atmospheric iron solubility varies depending on whether the particles are collected in rural or urban areas, with urban areas showing increased iron solubility. In this study, we investigate if the iron species present in different environments affects its ultimate solubility. Field data are presented from the Platte River Air Pollution and Photochemistry Experiment (PRAPPE), aimed at understanding the interactions between organic carbon and trace elements in atmospheric particulate matter (PM). 24‐hr PM2.5 samples were collected during the summer and winter (2016–2017), at three different sites on the Eastern Colorado plains: an urban, agricultural, and a mixed site. Downtown Denver had an average total and water‐soluble iron air concentration of 181.2 and 7.7 ng m−3, respectively. Platteville, the mixed site, had an average of total iron of 76.1 ng m−3, with average water‐soluble iron concentration of 9.1 ng m−3. Jackson State Park (rural/agricultural) had the lowest total iron average of 31.5 ng m−3 and the lowest water‐soluble iron average, 1.3 ng m−3. The iron oxidation state and chemical speciation of 97 samples across all sites and seasons was probed by X‐ray absorption near edge structure (XANES) spectroscopy. The most common iron phases observed were almandine (Fe₃Al₂Si₃O₁₂) (Denver 21%, Platteville 16%, Jackson 24%), magnetite (Fe3O4) (Denver 9%, Platteville 4%, Jackson 5%) and Fe (III)dextran (Denver 5%, Platteville 13%, Jackson 5%), a surrogate for Fe‐organic complexes. Additionally, native iron [Fe(0)] was found in significant amounts at all sites. No correlation was observed between iron solubility and iron oxidation state or chemical speciation.
Default mode and primary visual network coupling is associated with increased mind-wandering frequency in Parkinson’s disease with visual hallucinations

Background An imbalance between top-down expectations and incoming sensory information is implicated in the genesis of hallucinations across neuropsychiatric disorders. In Parkinson’s disease (PD) with visual hallucinations, over-activity in the default mode network (DMN) is a hypothesised source of excessive top-down influence that can dominate visual perception. Methods In 38 PD patients (18 with hallucinations; 20 without) and 20 age-matched controls, we administered a validated thought-sampling task to establish whether PD hallucinators experienced increased mind-wandering – a form of spontaneous thought strongly associated with DMN activity. Neural correlates of the behavioural differences in mind-wandering frequency were established via resting-state functional connectivity and voxel-based morphometry analyses. Results PD hallucinators (PD+VH) exhibited significantly higher mind-wandering frequencies compared to non-hallucinators (PD-VH), who showed reduced levels relative to controls. Inter-network connectivity and seed-to-voxel analyses confirmed increased mind-wandering in PD+VH was associated with greater coupling between the DMN and primary visual cortex (V1). In contrast, reduced mind-wandering was associated with grey matter loss in the left posterior parietal cortex in PD-VH. Conclusions Elevated mind-wandering associated with DMN-visual network coupling emerged as a distinguishing feature of PD hallucinators. We propose that increased mind-wandering reflects excessive spontaneous thought and mental imagery, which can furnish the content of visual hallucinations. DMN-V1 coupling may provide a neural substrate by which regions of the DMN exert disproportionate influence over ongoing visual perception. Our findings refine current models of visual hallucinations by identifying a specific cognitive feature and neural substrate consistent with the excessive top-down influences over perception that lead to hallucinations.
Shape‐stabilized phase change material with enhanced thermal conductivity fabricated based on biomimetic polymerization and in situ reduction of Cu ions

The thermal conductivity of shape‐stabilized phase change material of polyethylene glycols/porous carbon microspheresdoping withcopper particles (PEG/CARM‐Cu) was enhanced based on the adsorption and in situ reduction of Cu2+ using polydopamine microsphere (PDAM)material as the adsorbent. The synthesis of PDAM has the merits of simplicity and environmental friendliness, and the in situ reduction of Cu2+ through pyrolysis has the advantages of easy operation and cost effectiveness. Copper particles prepared by in situ reduction were tightly fixed on the surface of the support ofporous carbon microsphere (CARM), which avoided the sedimentation of copper particles during the phase change process of PEG/CARM‐Cu. According to the SEM, TEM, XRD, TGA and DSC test results, PEG/CARM‐Cu possessed favorable thermal reliability and stability, and the phase change enthalpy of PEG/CARM‐Cu‐2 could reach 101.50 J/g. Additionally, the thermal conductivity of PEG/CARM‐Cu‐2 (0.497 W/(m·K)) was enhanced by 93.3% compared to that ofpure PEG (0.257 W/(m·K)). Therefore, the PEG/CARM‐Cu developed in this paper possessed great potential for real applications.

DeepIDS: Deep Learning Approach for Intrusion Detection in Software Defined Networking

Software Defined Networking (SDN) is developing as a new solution for the development and innovation of the Internet. SDN is expected to be the ideal future for the Internet, since it can provide a controllable, dynamic, and cost-effective network. The emergence of SDN provides a unique opportunity to achieve network security in a more efficient and flexible manner. However, SDN also has original structural vulnerabilities, which are the centralized controller, the control-data interface and the control-application interface. These vulnerabilities can be exploited by intruders to conduct several types of attacks. In this paper, we propose a deep learning (DL) approach for a network intrusion detection system (DeepIDS) in the SDN architecture. Our models are trained and tested with the NSL-KDD dataset and achieved an accuracy of 80.7% and 90% for a Fully Connected Deep Neural Network (DNN) and a Gated Recurrent Neural Network (GRU-RNN), respectively. Through experiments, we confirm that the DL approach has the potential for flow-based anomaly detection in the SDN environment. We also evaluate the performance of our system in terms of throughput, latency, and resource utilization. Our test results show that DeepIDS does not affect the performance of the OpenFlow controller and so is a feasible approach.
Evaluation of large thyme and creeping bentgrass alcoholic extracts on human hepatocyte carcinoma cell lines.

Romania meadows are home to a great diversity of species. Some species are known to have some pytho-properties such as Thymus sp. varieties, but there are many other species that have been studied only as fodder plants such as of Agrostis sp. varieties. In this study, our aim is to analyze the antiproliferative characteristics of certain plant extracts. For this, were tested Thymus pulegioides L. and Agrostis stolonifera L. The plants alcoholic extracts were evaporated and then re-suspended in dimethyl sulfoxide. To assess the antitumor effect were used hepatic carcinoma cell line HepG2. The cells were cultivated in 90 micro liters of medium supplemented with 10 micro liters of extract in a final concentration of 25 and 50 mg/ml. The anti-proliferative effect was observed after 48 hours through spectrophotometric technique of MTT cellular proliferation. The following have been highlighted: the inhibition of cellular proliferation, dose dependency for Agrostis stolonifera products both in the case of extracts from leaves as well as those from the root, the inhibition rate being of 45% and 48% respectively. In the case of large thymus (Thymus pulegioides L.) extracts, cellular proliferation was observed only for the 50mg/ml dose, the rate of inhibition being of 37% for extracts from leaves, 39% for extracts from flowers and 26% for extracts from the stem. In conclusion, alcoholic extracts of the studied plants present therapeutic antitumor effects through the inhibition of in vivo multiplication of neoplastic cells. Further studies should be carried out for the biochemical characterization and the highlighting of the benefic effect in vivo. We believe that Locvei meadows mountains (Banat Mountains) constitute a reservoir of species with possible herbal effects and it is not yet sufficiently exploited.
The Impact of SST Biases in the Tropical East Pacific and Agulhas Current Region on Atmospheric Stationary Waves in the Southern Hemisphere

Climate models in the Coupled Model Intercomparison Project, Phase 5 (CMIP5) vary significantly in their ability to simulate the phase and amplitude of atmospheric stationary waves in the midlatitude Southern Hemisphere. These models also suffer from a double inter-tropical convergence zone (ITCZ), with excessive precipitation in the tropical eastern South Pacific, and many also suffer from a biased simulation of the dynamics of the Agulhas Current around the tip of South Africa. The intermodel spread in the magnitude of the strength and phasing of SH midlatitude stationary waves in the CMIP archive is shown to be significantly correlated with the double ITCZ bias and biases in the Agulhas Return Current. An idealized General Circulation Model (GCM) is used to demonstrate the causality of these links by prescribing an oceanic heat flux out of the tropical East Pacific and near the Agulhas Current. A warm bias in tropical east Pacific SSTs associated with an erroneous ”double” ITCZ leads to a biased representation of midlatitude stationary waves in the austral hemisphere, capturing the response evident in CMIP models. Similarly, an overly diffuse sea surface temperature gradient associated with a weak Agulhas Return Current leads to an equatorward shift of the Southern Hemisphere jet by more than 3◦ and weak stationary wave activity in the austral hemisphere. Hence, rectification of the double ITCZ bias and a better representation of the Agulhas Current should be expected to lead to an improved model representation of the austral hemisphere. 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38
La reproduction chez Oscarella lobularis (Porifera - Homoscleromorpha) : gènes impliqués et effets de l'environnement

Les Poriferes et les Ctenophores sont probablement les deux lignees animales les plus anciennes. Leur etude permet de retracer l’histoire precoce des metazoaires, et d’aborder l'origine de la distinction entre les lignees somatique et germinale. En effet, chez les eponges cette distinction n’existe pas: les archeocytes et choanocytes pouvant donner les cellules somatiques et les gametes.Apres avoir etabli la liste des genes consideres comme impliques dans la gametogenese chez les metazoaires, j’ai caracterise leurs sequences et retrace leur histoire grâce a des analyses comparatives integrant les principales lignees animales. Enfin, un suivi in situ d'Oscarella lobularis m’a permis d’affiner son cycle de vie et d’acceder a toutes les etapes du developpement pour etudier l’expression de ces genes et de tester leur implication dans la gametogenese.Ainsi, j'ai montre que 18 genes du GMP (Germline Multipotency Program) sont presents ancestralement chez les animaux. Parmi ceux-ci 11 s’expriment pendant la gametogenese, au cours de l’embryogenese, de la reproduction asexuee et de la regeneration. Enfin, le suivi in situ a montre l’influence de la variation de la temperature et de la matiere organique sur le declenchement de la gametogenese.Mon travail suggere d’une part, que la specification des cellules germinales est regie par des mecanismes genetiques communs a l’echelle de metazoaires, et d’autre part que ces genes pourraient etre impliques dans la multipotence. Ces resultats renforcent l’hypothese proposant une origine commune de la lignee germinale et des cellules souches somatiques.
Tourist choice of heritage sites in Romania: a conjoint choice model of site attributes and variety seeking behavior

ABSTRACT Romania owns a significant number of UNESCO listed heritage sites, but comparatively negligible tourist inflow. The information-seeking and the variety-seeking behavior of tourists among various types of heritage sites in Romania and associated peripheral attractions were explored from the TripAdvisor website and other resources. The travelers’ choice of heritage sites was clustered using a modified K-mean clustering technique, resulting in five clusters based on certain attributes of heritage sites, influencing the tourist’s choice of visit. Subsequently, a conjoint choice model is used to understand the role of heritage sites’ location along with their attributes and peripheral attractions that influences the choice of tourists. This study proposes strategies to the policymakers and tour operators to enhance Romanian tourism potential. The findings suggest that trips with low travel time and cost encourage the tourist decision. Policymakers should also develop peripheral attractions in most of the UNESCO heritage sites, which are remotely located. In addition, peripheral locations should promote the local culture and products with enhanced quality so as to attract more international as well as national travelers. Potential strategies to enhance tourist visits to various types of heritage sites viz religious, historic, and parks, in Romania have also been proposed.

Guanylate cyclase-activating proteins (GCAP1andGCAP2)arethoughttomediatetheintracellular stimulation of guanylate cyclase (GC) by Ca 21 , a key event in recoveryofthedarkstateofrodphotoreceptorsafterexposure to light. GCAP1 has been localized to rod and cone outer segments,thesitesofphototransduction,andtophotoreceptor synaptic terminals and some cone somata. We used in situ hybridizationandimmunocytochemistrytolocalizeGCAP2in human, monkey, and bovine retinas. In human and monkey retinas, the most intense immunolabeling with anti-GCAP2 antibodies was in the cone inner segments, somata, and synaptic terminals and, to a lesser degree, in rod inner segmentsandinnerretinalneurons.Inbovineretina,themost intense immunolabeling was in the rod inner segments, with weaker labeling of cone myoids, somata, and synapses. By using a GCAP2-specific antibody in enzymatic assays, we confirmed that GCAP1 but not GCAP2 is the major compo- nent that stimulates GC in bovine rod outer segment homog- enates.TheseresultssuggestthatalthoughGCAP1isinvolved in the Ca 21 -sensitive regulation of GC in rod and cone outer segments,GCAP2mayhavenon-phototransductionfunctions in photoreceptors and inner retinal neurons.
Graph Regularized Sparse Non-Negative Matrix Factorization for Clustering

The graph regularized nonnegative matrix factorization (GNMF) algorithms have received a lot of attention in the field of machine learning and data mining, as well as the square loss method is commonly used to measure the quality of reconstructed data. However, noise is introduced when data reconstruction is performed; and the square loss method is sensitive to noise, which leads to degradation in the performance of data analysis tasks. To solve this problem, a novel graph regularized sparse NMF (GSNMF) is proposed in this article. To obtain a cleaner data matrix to approximate the high-dimensional matrix, the $l_{1}$ -norm to the low-dimensional matrix is added to achieve the adjustment of data eigenvalues in the matrix and sparsity constraint. In addition, the corresponding inference and alternating iterative update algorithm to solve the optimization problem are given. Then, an extension of GSNMF, namely, graph regularized sparse nonnegative matrix trifactorization (GSNMTF), is proposed, and the detailed inference procedure is also shown. Finally, the experimental results on eight different datasets demonstrate that the proposed model has a good performance.
Lab-Scale, Closed-Loop Experimental Characterization, Model Refinement, and Validation of a Hydrokinetic Energy-Harvesting Ocean Kite

This paper presents a study wherein we experimentally characterize the dynamics and control system of a lab-scale ocean kite, and then refine, validate, and extrapolate this model for use in a full-scale system. Ocean kite systems, which harvest tidal and ocean current resources through high-efficiency cross-current motion, enable energy extraction with an order of magnitude less material (and cost) than stationary systems with the same rated power output. However, an ocean kite represents a nascent technology that is characterized by relatively complex dynamics and requires sophisticated control algorithms. In order to characterize the dynamics and control of ocean kite systems rapidly, at a relatively low cost, the authors have developed a lab-scale, closed-loop prototyping environment for characterizing tethered systems, whereby 3D printed systems are tethered and flown in a water channel environment. While this system has been shown to be capable of yielding similar dynamic characteristics to some full-scale systems, there are also fundamental limitations to the geometric scales and flow speeds within the water channel environment, making many other real-world scenarios impossible to replicate from the standpoint of dynamic similarity. To address these scenarios, we show how the lab-scale framework is used to refine and validate a scalable dynamic model of a tethered system, which can then be extrapolated to full-scale operation. In this work, we present an extensive case study of this model refinement, validation, and extrapolation on an ocean kite system intended for operation in the Gulf Stream or similar current environments.
Ribotipificación de aislamientos de Mannheimia haemolytica serotipo 1 obtenidos de exudado nasal de bovinos productores de leche en México

Se realizo la caracterizacion genetica de 106 aislamientos de Mannheimia haemolytica serotipo 1 (S1) obtenidos de exudado nasal de bovinos clinicamente sanos (BCS) (n= 80) y enfermos (BCE) (n= 26) de neumonia de dos granjas lecheras del centro y norte de Mexico, mediante la tecnica de ribotipificacion. De los cuales se extrajo el DNA para realizar el proceso de digestion con la endonucleasa de restriccion Hin dIII y la posterior ribotipificacion, que se realizo utilizando una sonda que contenia el operon rrn B rRNA. Se identificaron dos patrones de ribotipos: Rt1 y Rt2, en ambos casos, con bandas de hibridacion con tamanos aproximados entre 0.78 y 19.70 kb. El Rt1 presento 11 bandas de hibridacion y el Rt2 13. El 96 % de los aislamientos (102/106) se agruparon en un cluster dentro del Rt1. Entre el Rt1 y el Rt2 se presento un valor de similitud de 70 %. No se identificaron diferencias entre los Rt de los aislamientos de los animales BCS o BCE. Estos resultados indican que la mayoria de las cepas se agrupan dentro un mismo Rt (Rt1) conformando un solo cluster, independientemente del origen de las mismas y del estado de salud
Hyperspectral image classification using support vector machines

In this paper, a novel approach for hyperspectral image classification technique is presented using principal component analysis (PCA), bidimensional empirical mode decomposition (BEMD) and support vector machines (SVM). In this process, using PCA feature extraction technique on Hyperspectral Dataset, the first principal component is extracted. This component is supplied as input to BEMD algorithm, which divides the component into four parts, the first three parts represents intrensic mode functions (IMF) and last part shows the residue. These BIMFs and residue image is further taken as input to the SVM for classification. The results of experiments on two popular datasets of hyperspectral remote sensing scenes represent that the proposed-model offers a competitive analyticalperformance in comparison to some established methods.
Relationship between bull fertility and binding of 3H heparin to spermatozoa in Sahiwal-Friesian bull

A study was carried out to determine the effect of lyophilised heparin binding proteins (HBP) on the heparin binding ability of bovine epididymal spermatozoa and to determine the relationship between bull fertility and total binding of heparin to spermatozoa membrane. It was found that epididymal spermatozoa samples added with lyophilised HBP bound significantly higher (p 0.05) between post-thaw motility percentage of semen and heparin binding affinity of spermatozoa from the bulls. This showed that bulls with semen of high motility are not necessarily more fertile than those bulls with lower motility percentage.
