EnglishCo-operation between organisations is a marketing strategy that grows in a market characterised by high rates of globalisation and competitiveness. This is why co-operation allows SMEs to obtain greater benefits than they could achieve by working individually, since it facilitates the interchange of experience, information, and knowledge among workers. Hence, this paper’s objective is to analyse the co-operation rate inside ‘Aguascalientes’, an SME. The empirical analysis was carried out with a sample of 300 SMEs that had 5–250 workers. The resulting data showed that reduction on purchase costs; financial performance, and innovation have a significant positive influence on co-operation between different organisations.
Disaster Risk Reduction Programs and Their Effectiveness at Workplace in Industries, Eldoret Municipality, Kenya

According to the Kenya Minister of State for Special Programs (MSSP),Kenya lacks a comprehensive disaster preparedness policy. It has inefficient disaster management framework and strategies, which makes its economy and population highly vulnerable to natural and manmade disaster risks. Major disaster response initiatives are an ad hoc and short term and mainly comprising of emergency relief. It has previously managed some of them without an effective emergency system due to high level of support from the international community leading to huge costs to the country (GoK, 2009). This paper looks into the disaster risk reduction programs employed by industries at workplace in Eldoret Municipality, Kenya. The study employed survey and evaluation designs. Purposive sampling was used to select the industries and simple random sampling to select the study units which included; Managerial staff and workers of large, middle and small scale factories in Eldoret, labor officers in the Ministry of labor (Public Health Officers), fire brigade officers, Kenya National Environment Management Authority and the Kenya Red Cross Society Regional officials. Interviews and questionnaires were used for data collection from administrators and other factory employees while observation was used to identify risks within the workplace. Data was analyzed using descriptive statistics, frequencies, t -test, x 2 -square and ANOVA.It was concluded that Education and training is a major risk reduction measure that employers must have in place as a program to curb workplace hazards. They should ensure job applicants are adequately trained, and if not, provide for them on job training. The study therefore recommended that employers should ascertain the knowledge level of their employees before assigning them duties on machinery.

Uptake of diatoms in Baltic Sea macrozoobenthos during short-term exposure to severe and moderate hypoxia

The effect of severe and moderate hypoxia on food uptake of benthic macrofauna was studied in the laboratory. The hypothesis was that low oxygen concentrations negatively affect feed- ing at oxygen levels that have little effect on the studied animals' survival. The bivalve Macoma balthica, the priapulid Halicryptus spinulosus, the amphipods Monoporeia affinis (subadult & juve- nile) and Pontoporeia femorata (subadult) were offered the 14 C-labelled diatom Skeletonema costa- tum in 0.8 to 10.6 mg O2 l -1 . Feeding was measured as radioactivity uptake. Subadult amphipods were studied one species at a time (single) or together (mixed). Feeding changed in all amphipods at the lowest oxygen concentrations, but no effect was found for M. balthica and H. spinulosus. At the lowest concentration (0.8 mg O2 l -1 ) feeding by subadult M. affinis (single) was only 17% of the full oxygen saturation (10.6 mg O2 l -1 ), and, at 1.6 mg O2 l -1 , 14% of the feeding at 8.9 mg O2 l -1 . Juvenile M. affinis consumed more labelled algae at 3 mg O2 l -1 than at higher oxygen concentrations. M. balthica feeding was not affected. Little radioactivity uptake was registered for H. spinulosus at any oxygen concentration, showing that H. spinulosus is not a surface deposit feeder. The amphipods were the most sensitive to week-long oxygen deficiency. Survival decreased significantly in the lowest oxygen concentrations (0.8; 1.6 mg O2 l -1 ). Of the subadult M. affinis 15 and 65%, respectively, survived, compared with 0 and 58% for P. femorata. Juvenile M. affinis mortality was high in all oxygen concentrations, whereas most M. balthica and H. spinulosus survived.
Cassava Foliage for Monogastric Animals Forage Yield, Digestion, Influence on Gut Development and Nutritive Value

Khieu Borin, 2005. Cassava Foliage for Monogastric Animals: Forage Yield, Digestion, Influence on Gut Development and Nutritive Value. Doctoral thesis. ISSN 1652-6880, ISBN 91-576-6981-3 The study was aiming to evaluate cassava (Manihot esculenta Crantz) managed as a forage crop with respect to biomass yield, and to determine its value as a feed for monogastric animals. Two common cassava varieties, one short(ST) and one long-term (LT), grown in Cambodia, were studied with the aim of assessing forage yield, and effects on soil fertility and the utilization of the leaves as a feed for pigs and poultry. The ST variety was intercropped with Desmanthus virgatus or Gliricidia sepium and the LT variety was fertilised with effluent from biodigesters loaded with either cow (CM) or pig manure (PM). Intercropping of cassava with legumes increased total biomass dry matter (DM) yield and resulted in a higher proportion of cassava leaves, while fertilizing with PM produced the highest cassava total forage and leaf DM yields. The crude protein (CP) content on a DM basis in cassava leaf, and stem plus petiole, was 24-25% and 8-10%, respectively. It was estimated that D. virgatus and G. sepium fixed 1/3 and 1/2 of the amounts of nitrogen (N) removed by the cassava forage, respectively, while the N uptake was 67 and 27% above the N inputs from PM and CM, respectively. Both sun-drying and ensiling were efficient in reducing the hydrogen cyanide (HCN) content in cassava leaves, although ensiling after sun wilting was more effective. Pigs utilized the nutrients in cassava leaf silage (CLS) more efficiently than in cassava leaf meal (CLM) and leaves from the ST and LT varieties were utilized equally. Mong Cai (MC) pigs digested dietary fibre components better than Large White x Yorkshire (LxY) pigs, although N utilization was higher in LxY than MC pigs. Increasing CLM level in poultry diets slightly increased DM intake and decreased the digestibility of DM. Increasing dietary CLM increased the weight and length of most parts of the gastrointestinal tract (GIT) and associated internal organs, except for proventriculus weight and colon length. Broiler chickens and White Pekin ducks had higher GIT and internal organ weights and lengths than local ducks and chickens, respectively, when expressed in absolute units. However, when expressed as kg body weight, these values were higher in the local birds, except for small intestine weights, which were similar. Ducks had longer small intestines and higher small intestine, gizzard, pancreas and liver weights as kg body weight than chickens, while weights of caeca and colon, were higher in chickens. It is concluded that both ST and LT cassava varieties have the potential to produce high protein forage for monogastric animals. Pigs utilized cassava leaf silage more efficiently than sun-dried leaves. Increasing cassava leaf meal in the diet reduced DM digestibility and increased the length and weight of most parts of the gastrointestinal tract and associated organs of chickens and ducks.
An improved protocol for in vitro propagation of the medicinal plant Mimosa pudica L.

This work aimed to develop a protocol for the in vitro establishment, multiplication, rooting and ex vitro acclimatization of Mimosa pudica L. , a species used in folk medicine and with pharmacological activity. Aseptic cultures were established from seeds inoculated in MS medium, without growth regulators, followed by an in vitro stabilization phase in culture medium supplemented with 2.22 μM BAP. The cultures were transferred to MS medium supplemented with different cytokinins, combined or not with an auxin, aiming its large-scale propagation. The culture medium supplemented with 5 µM BAP plus 0.5 µM NAA provided the highest multiplication rate and top quality plantlets. The combination of 0.6 µM TDZ plus 0.05 µM NAA resulted in higher multiplication rates than in response to combination of BAP plus NAA, although the subsequent maintenance of the cultures in a medium without growth regulators has resulted in low regenerative response. In vitro rooting of micro-cuttings was high even in the absence of auxins. Over 90% of plantlets transferred to the greenhouse survived after the acclimatization phase. Acclimatized plants presented normal vegetative and reproductive development. The procedures established in the present study allow a massive production of M. pudica plants for further pharmacological studies. Key words: Biodiversity conservation, ex vitro acclimatization, in vitro rooting, micropropagation, Mimosa pudica.
From The Rapture to Left Behind: The Movie and Beyond: Evangelical Christian End Times Films from 1941 to the Present

This article traces the development of evangelical Christian ‘rapture films’ from the 1940s to the present day, focusing in particular on the place of the Left Behind series. In doing so, it locates the series within its genre; highlighting the ways in which it drew on, developed, and in some cases rejected earlier tropes, motifs and dramatis personae. Following on from this, the article will discuss the release of Left Behind: The Movie, its failure at the box office and critical panning, and the consequences that these have had on the rapture film industry. Finally, it concludes by discussing two recent releases by the mainstream production company The Asylum/Faith Films and what these mean for the future of the rapture film genre.

Small-Signal Modeling of the PVR-Based AD Scheme and Controller Design for Three-Phase Standalone DG System

This paper presents the small-signal state-space modeling and a new multifunctional multi-loop control strategy for three-phase inverter-based islanded DG systems under unbalanced and/or nonlinear load conditions. The proposed control methodology utilizes the parallel virtual resistance (PVR)-based active damping (AD) method for the islanded DG system using an extra feedback capacitor current shaping loop in the stationary reference frame to provide an AD to suppress the resonance-peak of the LC filter and improve both steady-state and transient performances, the inner voltage and current controllers are based on an enhanced proportional resonant (PR) structure to achieve zero steady-state error, and multi-resonant harmonic compensator (MRHC) plus PR controller to prevent low-order load current harmonics to distort the output voltage. The proposed small-signal model of the islanded DG system with multi-loop control strategy in the stationary reference frame is presented. Moreover, an enhanced delay compensation (EDC) scheme based on two integrators of the discrete PR controller is presented to improve stability margins with a higher accuracy compared with the existing methods. Then, a detailed systematic controller parameters design procedure is presented. Finally, simulation and experimental results are provided to validate the effectiveness of the proposed strategy.
Early Explorations On The Automatic Evolution Of Printable 3D Objects

Designing a 3D object is a very laborious process that usually involves expertise and time using various 3D design software. Numerous researchers have proposed mathematical formulas to automatically design in 2D space and has led to recent efforts being done on studies which use mathematical formulas to create objects in 3D space. Johan Gielis's Superformula that was generalized from the Supereclipse formula was able to gen- erate 3D shapes by extending the spherical product of the Superformula. In this research, the Superformula is use to automatically generate 3D object shapes through Evolutionary Programming that are free-form evolution and non target-based evolution as in most existing studies on automatic evolu- tion of 3D shapes. A novel fitness function was designed to evaluate the shapes generated by Superformula that serve as a part of the parent selection process in Evolutionary Programming. Through five experiments, the final objects generated from each run were selected to be printed out using 3D printing. Three out of five objects were successfully printed out from this automatic 3D object generationprocess. However, two objects were printed with deformation due to the thin layer of the object. From the observation gainedin the first five runs, the fitness function was then fine-tuned in order to evolve a more printable 3D object. From the fine-tuning another five runs were tested and the results show all five final objects from the evolution process were successfully printed out using a 3D printer with significantly less deformation due to thin layers.

Farm size as a factor in hydrodynamic transmission of pathogens in aquaculture fish production

Global aquaculture production has rapidly increased over recent decades, primarily through the increase in production per farm unit. However, size (biomass) may be a factor in the transmission of infectious diseases between hydrodynamically linked fish farms. A combined epi- demiological-simplified hydrodynamic model is used to demonstrate that as farm units increase they experience higher numbers of infections caused by a range of pathogen characteristics. The model demonstrates that as farm size increases in areas where faster currents prevail, there is a need to increase the separation distance between farms to prevent pathogen transmission. A com- parison of production regimes demonstrates, however, that fewer, highly separated, larger farms reduce overall losses compared to numerous smaller farms in close proximity to each other.
Quantum reversibility, decoherence and transport in dynamical systems

Depuis son apparition, aucune experience ou observation n'a jamais contredit la mecanique quantique. Cependant meme si notre monde est construit a partir de briques elementaires quantiques, il se comporte globalement de maniere classique. Ceci implique l'existence d'une transition quantique-classique. Cette derniere constitue l'objet de cette these. Cette transition a pour origine le processus de decoherence. Cette these traite l'interconnexion entre la notion de decoherence et trois aspects du chaos quantique. A savoir la notion de reversibilite quantique, l'intrication et finalement le transport quantique. Nous nous sommes d'abord concentre sur les fluctuations mesoscopiques de l'echo de Loschmidt. Puis nous avons generalise le concept afin d'y inclure un environnement. Nous avons ensuite aborde la notion d'intrication et son lien avec le principe de correspondance. Enfin nous avons traite le transport quantique et montre le caractere non universel du dephasage pour un regime semiclassique fort.
Classifier Ensembles Using Structural Features For Spammer Detection In Online Social Networks

Abstract As the online social network technology is gaining all time high popularity and usage, the malicious behavior and attacks of spammers are getting smarter and difficult to track. The newer spamming approaches using the social engineering concepts are making traditional spam and spammer detection techniques obsolete. Especially, content-based filtering of spam messages and spammer profiles in online social networks is becoming difficult. Newer approaches for spammer detection using topological features are gaining attention. Further, the evaluation of ensemble classifiers for detection of spammers over social networking behavior-based features is still in its infancy. In this paper, we present an ensemble learning method for online social network security by evaluating the performance of some basic ensemble classifiers over novel community-based social networking features of legitimate users and spammers in online social networks. The proposed method aims to identify topological and community-based features from users’ interaction network and uses popular classifier ensembles – bagging and boosting to identify spammers in online social networks. Experimental evaluation of the proposed method is done over a real-world data set with artificial spammers that follow a behavior as reported in earlier literature. The experimental results reveal that the identified features are highly discriminative to identify spammers in online social networks.
Ecological-Genetic Studies and Conservation of Endemic Quercus sideroxyla (Trel.) in Central Mexico

This study examines the distribution, ecology and genetic diversity of Quercus sideroxyla Humb. Bonpl, with an emphasis on its conservation on the Natural Protected Area of Sierra Fria in North Central Mexico. Twenty-nine locations were selected, and in each location, one plot of 1500 m2 was established. At every location, we obtained an abundance of Q. sideroxyla and a basal area for each individual tree, including geographical and climatological data. We used the Outlying Mean Index (OMI) to examine whether environmental conditions had a distributional effect on Q. sideroxyla populations and to obtain the static size population structure of the species. For the genetic analysis, we collected 18 adult individuals from each population, four polymorphic loci were used to estimate genetic diversity. Q. sideroxyla abundance was associated with narrow environmental conditions, especially when considering the topographical and meteorological environmental variables. The allelic richness value was 84 alleles (21 privatealleles), and the expected mean heterozygosity was 0.855 ± 0.009. The high vulnerability of the species to changes in the land use at the local scale and to global climatic changes increases the species’ susceptibility to local disappearance.
Chemically Synthesis and Characterization of Iron and Nickel Oxide Nanoparticles for Biomedicine

Magnetite (Fe3O4 and NiO) nanoparticles with a size range of 40–60 nm were prepared by sol-gel technique in nano and micro reverse micelles (water- in-oil). The surface properties, size, morphology and crystallographic structure of Fe3O4 and NiO particles are characterized by means of X-ray diffraction, transmission electron microscope and scanning electron microscope which will give much valuable information about these materials. In addition, synthesis of nanoparticles can be easily implemented because it is simple and environmentally friendly.

Dynamics and control of a novel buck-boost converter with low stresses on switches and diodes

Article history: Received 17 January 2017 Received in revised form 16 May 2017 Accepted 17 June 2017 This paper studies dynamics and control of a converter with advantages like: High step down gain, common ground between input and output terminal, positive output voltage and low voltage stress on switches and diodes. However, gate drive circuitry is more complex due to floatation of MOSFET sources. Converter’s small signal model is extracted using State Space Averaging (SSA). A controller is designed for the obtained model using MATLAB® control system toolbox. This paper shows that control of converter can be done using a simple Itype controller. This is another advantage for studied topology.
