Published: November 2019

Campylobacter, a common foodborne human pathogen, is considered sensitive to oxygen. Recently, aerotolerant (AT) Campylobacter jejuni with the ability to survive under aerobic stress has been reported. Here, we investigated the prevalence of hyper-aerotolerant (HAT) Campylobacter coli from duck sources (118 carcasses and meat) and its characteristics to assess potential impacts on public health. Half of 56 C. coli isolates were HAT and most harbored various virulence genes including flaA, cadF, cdtA, ceuB, and wlaN. Moreover, 98.2% of C. coli isolates showed resistance to quinolones, including ciprofloxacin (CIP), and nine (16.1%) showed high-level resistance to ciprofloxacin (Minimum Inhibitory Concentration, MIC ≥ 32 μg/mL) and most of these were HAT. Based on genetic relatedness between C. coli from duck sources and those from human sources (PubMLST and NCBI), HAT isolates sharing the same MLST sequence types were significantly more prevalent than those not sharing the same sequence types as those from human sources. Therefore, HAT C. coli is prevalent in duck sources, and is most likely transmitted to humans through the food chain given its aerotolerance. This being so, it might pose a threat to public health given its virulence and antimicrobial resistance (AMR). This study will assist in improving control strategies to reduce farm-to-table HAT C. coli transmission to humans.

Coagulase Negative Staphylococci (CoNS) are becoming increasingly recognized as an important cause of human and animal infections. Notwithstanding their clinical relevance, annotation of genes potentially involved in pathogenicity and/or antibiotic resistance in the CoNS species Staphylococcus arlettae (SAR) is currently very limited. In the current work we describe the genome of a novel methicillin resistant isolate of SAR, which we named Bari, and present a comprehensive analysis of predicted antibiotic resistance profiles and virulence determinants for all the 22 currently available SAR genomes. By comparing predicted antibiotic resistance and virulence-associated genes with those obtained from a manual selection of 148 bacterial strains belonging to 14 different species of staphylococci and to two “outgroup” species, Bacillus subtilis (BS) and Macrococcus caseoliticus (MC), we derived some interesting observations concerning the types and number of antibiotic resistance-related and virulence-like genes in SAR. Interestingly, almost 50% of the putative antibiotic resistance determinants identified in this work, which include the clinically relevant mec, van, and cls genes, were shared among all the SAR strains herein considered (Bari included). Moreover, comparison of predicted antibiotic resistance profiles suggest that SAR is closely related to well-known pathogenic Staphylococcus species, such as Staphylococcus aureus (SA) and Staphylococcus epidermidis (SE). A similar analysis of predicted virulence factors, revealed that several genes associated with pathogenesis (including, for example, ica, nuc, and ssp), which are commonly found in the genomes of pathogenic staphylococci such as Staphylococcus haemolyticus (SH) and Staphylococcus saprophyticus (SS), are observed also in the SAR strains for which a genomic sequence is available. All in all, we believe that the analyses presented in the current study, by providing a consistent and comprehensive annotation of virulence and antibiotic resistance-related genes in SAR, can constitute a valuable resource for the study of molecular mechanisms of opportunistic pathogenicity in this species.

Published: November 2019

The hydrolysis–condensation reactions of m-tolyl, m-chlorophenyl, and α-naphtyl-trichlorsilanes, (1, 2, and 3, respectively) in water-acetone solutions were examined for how they were influenced by the change in the concentration of HCl (CHCl). The composition of the products was monitored by 29Si NMR spectroscopy and atmospheric pressure chemical ionization mass spectrometry (APCI-MS). The acidity of the medium was shown to affect the yields of the products, and so, what products were formed. For 3, e.g., APCI-MS showed peaks of α-naphtyl-T8 and α-naphtyl-T10 as the most abundant in the spectra taken after 48 and 240 h for the reaction conducted at CHCl = 0.037 mol L−1. Unlike this, at CHCl = 0.15 mol L−1, those peaks were of [α-naphtyl(HO)2SiO]2(α-naphtyl)(HO)Si and/or [α-naphtyl(HO)Si]3, [α-naphtyl(HO)Si]4,5, and α-naphtyl-T8 after 192 h. However, at both CHCl values, the main product (and an intermediate) after 24 h was trans-1,1,3,3-tetrahydroxy-1,3-di-α-naphtyldisiloxane. It was isolated and its structure established by 1H-, 29Si-NMR, and X-ray powder diffraction.

Published: November 2019

A number of new symmetrically and asymmetrically 2,3-disubstituted quinoxalines were synthesized through functionalization of 2,3-dichloroquinoxaline (2,3-DCQ) with a variety of sulfur and/or nitrogen nucleophiles. The structures of the obtained compounds were established based on their spectral data and elemental analysis. The antimicrobial activity for the prepared compounds was investigated against four bacterial species and two fungal strains. The symmetrically disubstituted quinoxalines 2, 3, 4, and 5 displayed the most significant antibacterial activity, while compounds 6a, 6b, and the pentacyclic compound 10 showed considerable antifungal activity. Furthermore, compounds 3f, 6b showed broad antimicrobial spectrum against most of the tested strains.

Published: November 2019

Neoparamoba perurans, is the aetiological agent of amoebic gill disease (AGD), a disease that affects farmed Atlantic salmon worldwide. Multilocus sequence typing (MLST) and Random Amplified Polymorphic DNA (RAPD) are PCR-based typing methods that allow for the highly reproducible genetic analysis of population structure within microbial species. To the best of our knowledge, this study represents the first use of these typing methods applied to N. perurans with the objective of distinguishing geographical isolates. These analyses were applied to a total of 16 isolates from Australia, Canada, Ireland, Scotland, Norway, and the USA. All the samples from Australia came from farm sites on the island state of Tasmania. Genetic polymorphism among isolates was more evident from the RAPD analysis compared to the MLST that used conserved housekeeping genes. Both techniques consistently identified that isolates of N. perurans from Tasmania, Australia were more similar to each other than to the isolates from other countries. While genetic differences were identified between geographical isolates, a BURST analysis provided no evidence of a founder genotype. This suggests that emerging outbreaks of AGD are not due to rapid translocation of this important salmonid pathogen from the same area.
Empirical Analysis of Safe Distance Calculation by the Stereoscopic Capturing and Processing of Images Through the Tailigator System
Authors: Krizek Gerd Christian , Hausleitner Rene , Böhme Laura , Olaverri-Monreal Cristina
Published: November 2019

Driver disregard for the minimum safety distance increases the probability of rear-end collisions. In order to contribute to active safety on the road, we propose in this work a low-cost Forward Collision Warning system that captures and processes images. Using cameras located in the rear section of a leading vehicle, this system serves the purpose of discouraging tailgating behavior from the vehicle driving behind. We perform in this paper the pertinent field tests to assess system performance, focusing on the calculated distance from the processing of images and the error margins in a straight line, as well as in a curve. Based on the evaluation results, the current version of the Tailigator can be used at speeds up to 50 km per hour without any restrictions. The measurements showed similar characteristics both on the straight line and in the curve. At close distances, between 3 and 5 m, the values deviated from the real value. At average distances, around 10 to 15 m, the Tailigator achieved the best results. From distances higher than 20 m, the deviations increased steadily with the distance. We contribute to the state of the art with an innovative low-cost system to identify tailgating behavior and raise awareness, which works independently of the rear vehicle’s communication capabilities or equipment.

Published: November 2019

For the time-consuming and stressful body measuring task of Qinchuan cattle and farmers, the demand for the automatic measurement of body dimensions has become more and more urgent. It is necessary to explore automatic measurements with deep learning to improve breeding efficiency and promote the development of industry. In this paper, a novel approach to measuring the body dimensions of live Qinchuan cattle with on transfer learning is proposed. Deep learning of the Kd-network was trained with classical three-dimensional (3D) point cloud datasets (PCD) of the ShapeNet datasets. After a series of processes of PCD sensed by the light detection and ranging (LiDAR) sensor, the cattle silhouettes could be extracted, which after augmentation could be applied as an input layer to the Kd-network. With the output of a convolutional layer of the trained deep model, the output layer of the deep model could be applied to pre-train the full connection network. The TrAdaBoost algorithm was employed to transfer the pre-trained convolutional layer and full connection of the deep model. To classify and recognize the PCD of the cattle silhouette, the average accuracy rate after training with transfer learning could reach up to 93.6%. On the basis of silhouette extraction, the candidate region of the feature surface shape could be extracted with mean curvature and Gaussian curvature. After the computation of the FPFH (fast point feature histogram) of the surface shape, the center of the feature surface could be recognized and the body dimensions of the cattle could finally be calculated. The experimental results showed that the comprehensive error of body dimensions was close to 2%, which could provide a feasible approach to the non-contact observations of the bodies of large physique livestock without any human intervention.
Comparison of Three Algorithms for the Retrieval of Land Surface Temperature from Landsat 8 Images
Authors: Wang Lei , Lu Yao , Yao Yunlong
Published: November 2019

The successful launch of the Landsat 8 satellite provides important data for the monitoring of urban heat island effects. Since the Landsat 8 TIRS data has two thermal infrared bands, it is suitable for many algorithms to retrieve the land surface temperature (LST). However, the selection of algorithms for retrieving the LST, the acquisition of algorithm input parameters, and the verification of the results are problems without obvious solutions. Taking Changchun City as an example, this paper used the mono-window algorithm (MWA), the split window algorithm (SWA), and the single-channel (SC) method to extract the LST from the Landsat 8 image and compared the three algorithms in terms of input parameters, accuracy, and sensitivity. The results show that all three algorithms can achieve good results in retrieving the LST. The SWA is the least sensitive to the error of the input parameters. The MWA and the SC method are sensitive to the error of the input parameters, and compared with the error of the LSE, these two algorithms are more sensitive to the error of atmospheric water vapor content. In addition, the MWA is also very sensitive to the error of the effective mean atmospheric temperature.
Evaluating Probabilistic Traffic Load Effects on Large Bridges Using Long-Term Traffic Monitoring Data
Authors: Lu Naiwei , Ma Yafei , Liu Yang
Published: November 2019

With the steadily growing of global transportation market, the traffic load has increased dramatically over the past decades, which may develop into a risk source for existing bridges. The simultaneous presence of heavy trucks that are random in nature governs the serviceability limit for large bridges. This study investigated probabilistic traffic load effects on large bridges under actual heavy traffic load. Initially, critical stochastic traffic loading scenarios were simulated based on millions of traffic monitoring data in a highway bridge in China. A methodology of extrapolating maximum traffic load effects was presented based on the level-crossing theory. The effectiveness of the proposed method was demonstrated by probabilistic deflection investigation of a suspension bridge. Influence of traffic density variation and overloading control on the maximum deflection was investigated as recommendations for designers and managers. The numerical results show that the congested traffic mostly governs the critical traffic load effects on large bridges. Traffic growth results in higher maximum deformations and probabilities of failure of the bridge in its lifetime. Since the critical loading scenario contains multi-types of overloaded trucks, an effective overloading control measure has a remarkable influence on the lifetime maximum deflection. The stochastic traffic model and corresponding computational framework is expected to be developed to more types of bridges.
Exploring the Contributions of an Immersive, Environmental Education Workshop on Pre-Service Teachers’ Environmental Education Preparedness
Authors: Scott Joey , Sulsberger Megan J.
Published: November 2019

Public schools are an important place to cultivate environmental agency in children, and classroom teachers play an important role in this identity process. Teachers who afford opportunities for environmental learning and care behaviors to develop during the school day play an important role in cultivating the next generation of environmental stewards. Pre-service teacher populations bring additional promise to the future development of stewardship in schools, as their teaching philosophies and early career plans are still emerging and amenable. Providing purposeful, interactive, environmental education programming within the context of teacher training programs may be an important factor in positively impacting pre-service teachers’ (PSTs) confidence, willingness, and/or sense of preparedness to implement environmental learning in their future classrooms. Utilizing a mixed-methods approach, this study examined the potential impacts an immersive, environmental education workshop conducted at the Monterey Bay Aquarium in Monterey, CA had on a group of 61 elementary education PSTs during their teacher preparation program at California State University Monterey Bay (CSUMB). After participating in a variety of ocean-themed activities and empathy exercises, data collected through pre- and post-surveys indicated that this immersive, environmental experience contributed to PSTs perceived confidence and preparedness as future classroom-based, environmental educators. Through the reported development of their environmental confidence and interest in accessing supplementary resources, PSTs’ ability to act on behalf of the environment by planning environmental learning in their future classrooms becomes a springboard for additional training and support.
Factors affecting use of unscheduled care for people with advanced cancer: a retrospective cohort study in Scotland
Authors: Mills Sarah , Buchanan Deans , Guthrie Bruce , Donnan Peter , Smith Blair
Published: November 2019

Background

People with advanced cancer frequently attend unscheduled care, but little is known about the factors influencing presentations. Most research focuses on accident and emergency (A&E) and does not consider GP out-of-hours (GPOOH).

Aim

To describe the frequency and patterns of unscheduled care use by people with cancer in their last year of life and to examine the associations of demographic and clinical factors with unscheduled care attendance.

Design and setting

Retrospective cohort study of all 2443 people who died from cancer in Tayside, Scotland, during 2012–2015. Clinical population datasets were linked to routinely collected clinical data using the Community Health Index (CHI) number.

Method

Anonymised CHI-linked data were analysed in SafeHaven, with descriptive analysis, using binary logistic regression for adjusted associations.

Results

Of the people who died from cancer, 77.9% (n = 1904) attended unscheduled care in the year before death. Among unscheduled care users, most only attended GPOOH (n = 1070, 56.2%), with the rest attending A&E only (n = 204, 10.7%), or both (n = 630, 33.1%). Many attendances occurred in the last week (n =1360, 19.7%), last 4 weeks (n = 2541, 36.7%), and last 12 weeks (n = 4174, 60.3%) of life. Age, sex, deprivation, and cancer type were not significantly associated with unscheduled care attendance. People living in rural areas were less likely to attend unscheduled care: adjusted odds ratio (aOR) 0.64 (95% confidence interval = 0.50 to 0.82). Pain was the commonest coded clinical reason for presenting (GPOOH: n = 482, 10.5%; A&E: n = 336, 28.8%). Of people dying from cancer, n = 514, 21.0%, were frequent users (≥5 attendances/year), and accounted for over half (n = 3986, 57.7%) of unscheduled care attendances.

Conclusion

Unscheduled care attendance by people with advanced cancer was substantially higher than previously reported, increased dramatically towards the end of life, was largely independent of demographic factors and cancer type, and was commonly for pain and palliative care.

Authors: Wang Huan , Mao Chen Yu , Deng Jing , Jin Xi , Xu Nong
Published: November 2019

Objective

Obesity is related to various diseases and the risk of cancer. However, most studies overemphasize the risk of obesity, while ignoring the impact of underweight. In this study, we carried out a metaanalysis to assess the impact of a low preoperative body mass index on the postoperative complication and overall survival rates of gastric cancer patients.

Methods

We identified and selected relevant studies through PubMed, Embase, the Cochrane Library databases, the web of science, China National Knowledge Infrastructure and Wanfang electronic databases up to February 2019. The relative risk and 95% confidence interval were used to assess the association between the BMI and outcomes of gastric cancer patients.

Results

Seventeen publications were included in the final meta-analysis. There was a significant increase in the risk of postoperative complications (RR: 1.30, 95% CI: 1.07 - 1.57, P < 0.05; I2
=61.1%) in the patients with a low body mass index.

Conclusion

Further research, including larger-scale prospective studies, is needed to confirm this finding. For underweight patients with poor nutritional status, preoperative nutritional support and BMI adjustment may be helpful to improve the postoperative outcomes.

Authors: Ding Jie , Wang Hao , Kang Xing , Wang Feng , Chen Hong , Feng Min , Guan Wen Xian
Published: November 2019

Objective

To determine the effects of alcohol on the invasion and proliferation of gastric cancer.

Methods

In an in vitro study, gastric cancer cells were treated with different concentrations of alcohol. The protein levels of matrix metalloproteinase (MMP)2/7/9/13, Cyclin D and PCNA were determined by Western blot. The transcription levels of MMP2/7/9/13 were determined by qRT-PCR. An MMPs inhibitor (GM6001) was used to analyze the role of MMPs in the invasion of gastric cancer cells. In an in vivo experiment, the effects of alcohol on the proliferation of gastric cancer was analyzed in a heterotopic transplantation animal tumor model.

Results

The protein levels of MMP2/7/9/13 were increased in gastric cancer cells (AGS and HGC-27) compared with normal gastric epithelial cells (GES). Alcohol treatment resulted in further elevation of the MMPs expression in the cancer cells and promoted the invasion of the gastric cancer cells. GM6001 inhibited these effects. In addition, alcohol treatment promoted the expression of Cyclin D and PCNA in cancer cells and gastric tumor proliferation in the animal model.

Conclusion

Alcohol consumption promoted the invasion and proliferation of gastric cancer. Confirmation should be obtained in further studies in additional models.
Narodi, religije in misijon v dokumentih drugega vatikanskega koncila
Authors: Avsenik Nabergoj Irena
Published: November 2019

Z izbruhom prve in druge svetovne vojne in z nastopom globalizacije, ki je zajela ves svet, je vodstvo Cerkve moralo odgovoriti na izziv gospodarskega, političnega, vzgojnega in kulturnega sodelovanja med vsemi narodi. Ta izziv je koncilske očete drugega vatikanskega zbora tako pritegnil, da so v primarnih virih Svetega pisma in cerkvenih očetov poiskali besedila, ki najbolj jasno in enoumno govorijo o misijonski naravi Cerkve kot vesoljnega občestva ljudi, podobno ali enako hrepenečih po sreči in ljubezni, pa tudi enako ali podobno trpečih zaradi zemeljske omejenosti človekovega življenja. Vračanje v duhovne vire Svetega pisma, ki vrh svojega sporočila doseže v zapovedi ljubezni do Boga in do sočloveka, omogoča nenehno prečiščevanje hermenevtike misijona, tako na strokovni ravni kakor tudi na ravni živete resnice po vzoru božje ljubezni do vseh ljudi na svetu. Članek po kronološkem redu obravnava koncilske dokumente, ki izražajo nove poglede koncilskih očetov na vlogo narodov, religij in misijona v perspektivi svetopisemskega razodetja: Konstitucijo o svetem bogoslužju; Izjavo o razmerju Cerkve do nekrščanskih verstev; Dogmatično konstitucijo o Cerkvi; Odlok o misijonski dejavnosti Cerkve in Pastoralno konstitucijo o Cerkvi v sedanjem svetu.
Pomen Baragovega misijonskega delovanja pri uresničevanju Zakona o izselitvi Indijancev iz leta 1830
Authors: Marković Irena
Published: November 2019

Prispevek obravnava izselitveno politiko ZDA do indijanskih plemen vzhodno od reke Misisipi, ki je bila utemeljena z nakupom Louisiane leta 1803 in z izvajanjem »civilizacijskega načrta«. S tem načrtom so bili postavljeni temelji za politiko zvezne vlade do Indijancev in za njihovo izselitev zahodno od reke Misisipi. S sprejetjem Zakona o izselitvi Indijancev leta 1830 se je začelo obdobje sistematičnega nasilnega izseljevanja Indijancev zahodno od reke Misisipi, ki so bili deležni etnocidnih pritiskov takratne uradne ameriške politike. Leta izvajanja tega zakona se časovno prekrivajo z začetki delovanja slovenskega misijonarja in škofa Ireneja Friderika Baraga (1797–1868) med Indijanci. Uspeh njegovega delovanja in njegovih naslednikov se ne kaže le v širjenju krščanskega nauka in pismenosti med Otavci in Očipvejci, ampak tudi v njihovem prilaganju belskemu načinu življenja; prav zato vlada ZDA pretežnega dela teh dveh indijanskih plemen ni izselila zahodno od reke Misisipi na podlagi Zakona o izselitvi Indijancev leta 1830.

El propósito de este artículo es realizar un análisis de los factores motivación, ansiedad y autoestima en el aprendizaje del inglés como lengua extranjera. Se revisaron de manera crítica las nociones, tipologías y perspectivas relacionadas con cada uno de estos factores socio-afectivos y su incidencia en el aprendizaje de una lengua extranjera. Se encontró que éstos influyen notoriamente en el éxito o fracaso en el proceso de aprendizaje de un idioma y que entran en relaciones directas o inversas debido a su relativa autonomía. En adición a los factores personales se describieron los factores contextuales y se asumió como determinante el papel que juega el profesor como agente pedagógico, ya que éste incide de alguna manera en el comportamiento y actitud de los estudiantes en el aula de clase. Finalmente, se estableció que los factores personales y contextuales no operan de manera aislada, sino que se presuponen mutuamente. El artículo tiene un gran significado para los docentes, ya que les permite reconocer la importancia que juegan los factores socio-afectivos en el aprendizaje de un idioma y, por lo tanto, incorporar en su labor estrategias flexibles que permitan desarrollar un ambiente favorable para el aprendizaje.

Del consenso a la discordia: Estado y empresas multinacionales en la era kirchnerista (Argentina, 2003-2015)
Authors: Dulitzky Alejandro
Published: November 2019

En este trabajo se analiza la relación que mantuvieron las empresas multinacionales más importantes de la Argentina con los gobiernos kirchneristas durante el período 2003-2015. El análisis del contenido de las medidas económicas de la etapa, el contexto en el que fueron implementadas, y las reacciones que suscitaron en las empresas extranjeras y sus representantes, permite advertir tres momentos en la relación de éstas  con el gobierno: una primera etapa caracterizada por un diálogo abierto y un auge en las negociaciones entre empresas y gobierno; un segundo período signado por el crecimiento de las tensiones y la clausura progresiva del diálogo; y una última etapa caracterizada por la centralización de las decisiones en un grupo reducido de actores estatales y una marcada distancia entre las empresas multinacionales y el gobierno.

Este trabajo pone el énfasis en la validación del Modelo de Indicadores de Evaluación en el Espacio Europeo de Educación Superior propuesto como respuesta a la incorporación de las universidades españolas al proceso de convergencia europea. Los objetivos perseguidos se han centrado en establecer la relevancia de cada una de las dimensiones establecidas en el modelo, clasificar cada uno de los indicadores en función de la información que ofrecen y de sus repercusiones posteriores y determinar los usos adecuados de cada uno de ellos, de manera que puedan ser utilizados en propuestas de evaluación institucional universitaria y en la búsqueda efectiva de la calidad de las instituciones de educación superior. Para ello, hemos seguido un proceso de validación del modelo desde una doble perspectiva: en primer lugar, se ha aplicado el método Delphi de evaluación para valorar la relevancia y la pertinencia de los indicadores y sus variables concomitantes dentro del modelo con la ayuda de expertos de diferentes universidades españolas y, en segundo lugar, se inició un proceso de validación tras una puesta en práctica experimental del modelo definitivo derivado de este primer método, donde el alumnado hizo una valoración del mismo haciendo un juicio de valor personalizado de la importancia otorgada a las diferentes dimensiones e indicadores y aportando cuantas sugerencias estimaron oportunas para confeccionar la propuesta final. El modelo definitivo se define como un sistema de indicadores genérico y con un grado de apertura considerable. Está formado por un total de 6 competencias, 19 indicadores y 85 variables que definen los estándares que sirven para valorar la formación universitaria del alumnado. Su finalidad es proveer de conocimiento a la institución y a los integrantes de toda la comunidad universitaria para la posterior toma de decisiones para alcanza la mejora continua
Currículo e pedagogia nos liceus portugueses entre a Monarquia e a República: as reformas do ensino secundário de 1905 e 1917
Authors: Oliveira Casulo José Carlos de
Published: November 2019

Em 1910, a multissecular monarquia portuguesa deu lugar a um regime republicano. Preocupação cimeira dos responsáveis pela nova ordem política foi a educação. No tocante ao ensino secundário, ministrado nos liceus, a primeira reforma republicana foi levada a cabo em 1917, por Joaquim Pedro Martins, precisamente doze anos depois da última reforma monárquica deste nível de ensino, realizada em 1905 por Eduardo José Coelho. Neste artigo, sob o ponto de vista dos seus currículos, dos seus objectivos gerais e das suas directrizes pedagógico-fundamentais essenciais, estudam-se ambas as reformas no sentido de averiguar se se verificou, ou não, no ensino liceal português da época e nos aspectos acima referidos, uma transição com alterações tão substanciais quanto aquelas que se deram na forma política do Estado. Introdutoriamente enquadra-se e esclarece-se o teor fundamental do artigo, seguindo-se a análise das reformas em causa, finda a qual se apresentam as conclusões da investigação feita e a bibliografia a considerar.

Solar Energy is the one of best renewable source of alternative energy. The efficiency of the solar panel can be improved more by tracking it in such way that it always faces perpendicular to the sun-rays throughout the day rather than it is kept fixed at an angle. At present, there are three methods for solar tracking, out of which refrigerant method is found to be more efficient as it is of a passive type and requires no external power source for its operation. In this project we have used R-134a [Tetrafluoroethene (CF3CH2F)] as the refrigerant medium for tracking the panel. To store the refrigerant, we have made use of two canisters and a copper conduit for connecting the canisters. The tracking system works on the principle of Differential Pressure Controlled system where high-pressure refrigerant from one canister to other flows and due to imbalance in the weight of canisters, the panel will tilt in the direction of the side where the weight is high due to gravity. Thus, our main objective is to harvest more solar energy at a much lower cost than the available trackers.

In a code division multiple access (CDMA) system, multiple access interference (MAI) and Inter-symbol interference (ISI) appears if generated spreading codes are not maintained orthogonally and the communication channel is taken as multi-path communication channel. When generated spreading codes are multi-path spread and then channel delay occurs, it shows that ortho-gonality of the spreading codes is not maintained. The effect of MAI can be mitigated by maintaining low cross-correlation values as much as low between the large numbers of spreading codes. The code division multiple technique spreading codes must maintain absolutely impulsive autocorrelation at origin and very low cross correlation other than origin to avoid false synchronisation. i.e autocorrelation must be maximum at origin and cross correlation must be minimum at non origin point. In this paper, we propose multi-objective Genetic Algorithm approach –Genetic Algorithm-II (NSGA-II) to reduce the out-of-phase average mean-square aperiodic autocorrelation and average mean-square aperiodic cross-correlation value of randomly initialized binary spreading code set
