Impact of Business Incubators’ Facilities on Entrepreneurial Ecosystem Creation: A Case of Business Incubator in Jordan

This study aims at reflecting the impact of business incubator facilities on the creation of an entrepreneurial ecosystem with a focus on the major business incubator in Jordan—King Hussein Business Park—as it expanded new land within a critical large expansion plan through five phases with a full occupancy rate. This example shows more details on how to further develop planned entrepreneurial activities to attract new clients to occupy expanded spaces by focusing on creating a supportive ecosystem for entrepreneurship. This study was conducted on the top and middle management of the companies in the business hub KHBP, the sample consisted of (300) directors. In this context, infrastructure, governmental tax benefits, and services provided are hypothesized to have an effect on the entrepreneurial ecosystem in addition to that the outcomes of this study disclose a favorable influence for the facilities on creation supportive entrepreneurial climate. Infrastructure, Governmental law benefits, and services are found to be significant in the creation of a charming business climate for entrepreneurs. The study’s findings demonstrate that countries with scant exchequers face a lot of troubles in creating an attractive and supportive ecosystem for entrepreneurial activities, and they have to get better their business environment for entrepreneurship development. Governmental policies and reforms also play a vital role in making the projects and businesses much simply.
Neonatal overfeeding induced by reducing the litter size leads to an obese phenotype and increases preference for sweet food in adult male rats.

Aim: the aim of this study was to induce obesity in rats using the neonatal overfeeding protocol and evaluate in adult male animals standard chow intake, sweet food intake, the preference between sweet food and standard chow, locomotor activity and anxiety-like behavior. Methodology: The neonatal overfeeding protocol consisted of reducing the litter size to 4 animals (small litters = SL) compared to 8 animals in normal litters (NL). In these experiments we used 55 offspring from 18 litters. Results: obesity was successfully induced as observed by increased body weight and Original Research Article British Journal of Medicine & Medical Research, 4(4): 957-968, 2014 958 depots of abdominal fat in SL animals compared to NL; [F(1, 53)=15.018; P<. 001] for body weight and [t(48.06)=2.186 P=. 03] for abdominal fat.No difference between groups was found in standard chow [t (16)=1.843 P=. 08] and sweet food intake [t(53)=0.453 P=. 65], however in the test that evaluated the preference between both foods SL animals consumed more sweet food than NL [t(48) =2.481 P=. 02]. Additionally, there was no difference between groups regarding locomotor activity [t(52)=0.073 P=. 94] but SL animals showed reduced anxiety-like behavior compared to NL [t(39.36)=2.205 P=. 03]. Conclusion: this study supports the use of neonatal overfeeding protocol as a model of early obesity and showed for the first time the increased preference for sweet food in adult neonatal overfed animals.
Effect of feeding frequency and feeding rate on growth of Oreochromis mossambicus (Teleostei: Cichlidae) fry

The effect of feeding frequency and feeding rate on growth of Oreochromis mossambicus fry was investigated over 30 d under temperature- and light-cycle-controlled conditions on the University of Zululand campus, South Africa, in October and November 2009. Weight gain, specific growth rate and gross food conversion ratio were significantly affected by feeding frequency, but survival rate was not significantly affected; the best results were obtained at a feeding frequency of four times per day. Feeding rate significantly affected weight gain and gross food conversion ratio, but not the specific growth rate or survival rate. Taking into consideration weight gain, specific growth rate and gross food conversion ratio, feeding four times per day at a rate of 15% body weight per day is optimal for fry growth.
Metabolic activity of Flavobacterium strain P25 during starvation and after introduction into bulk soil and the rhizosphere of wheat

The physiological state of introduced Flavobacterium strain P25 cells was determined in starvation cultures, in bulk soil, and in the rhizosphere of wheat using direct viable counts (DVC; based on cell elongation after use of nalidixic acid and substrate addition, resulting in a potential activity measurement) and the redox dye 5-cyano-2, 3-ditolyl tetrazolium chloride (CTC; based on respiration without substrate additions, resulting in an in situ activity measurement). Both methods clearly demonstrated that the metabolic activity of Flavobacterium P25 cells decreased during starvation, followed by increased activity after amendment with substrate. This confirmed the applicability of DVC and CTC methods to Flavobacterium P25. Both DVC and CTC methods showed that the percentage of active cells in an introduced Flavobacterium P25 population in rhizosphere soil was lower than that in bulk soil in the first 1–2 weeks after planting wheat seedlings. After two weeks, the percentage of metabolically active cells in the P25 population in rhizosphere soil was higher than in bulk soil. Since different aspects of cellular physiology are measured when applying DVC and CTC, the impact of variations in environmental factors on the metabolic state of introduced strains may be monitored closely by these methods.
Binding of Destabilized βB2-Crystallin Mutants to α-Crystallin

Age-related changes in protein-protein interactions in the lens play a critical role in the temporal evolution of its optical properties. In the relatively non-regenerating environment of the fiber cells, a critical determinant of these interactions is partial or global unfolding as a consequence of post-translational modifications or chemical damage to individual crystallins. One type of attractive force involves the recognition by α-crystallins of modified proteins prone to unfolding and aggregation. In this paper, we explore the energetic threshold and the structural determinants for the formation of a stable complex between α-crystallin and βB2-crystallin as a consequence of destabilizing mutations in the latter. The mutations were designed in the framework of a folding model that proposes the equilibrium population of a monomeric intermediate. Binding to α-crystallin is detected through changes in the emission properties of a bimane fluorescent probe site-specifically introduced at a solvent exposed site in βB2-crystallin. α-Crystallin binds the various βB2-crystallin mutants, although with a significantly lower affinity relative to destabilized T4 lysozyme mutants. The extent of binding, while reflective of the overall destabilization, is determined by the dynamic population of a folding intermediate. The existence of the intermediate is inferred from the biphasic bimane emission unfolding curve of a mutant designed to disrupt interactions at the dimer interface. The results of this paper are consistent with a model in which the interaction of α-crystallins with substrates is not solely triggered by an energetic threshold but also by the population of excited states even under favorable folding conditions. The ability of α-crystallin to detect subtle changes in the population of βB2-crystallin excited states supports a central role for this chaperone in delaying aggregation and scattering in the lens.
Active vibration control of a mounting bracket for automotive gearboxes

The aim of this paper is to investigate the use of active vibration control in automotive gearboxes mounting brackets to reduce tonal disturbances. A combination of piezoelectric accelerometers and an internally preloaded piezo stack actuator is used to counteract their unbalanced caused vibrations. Initially, a numerical modal analysis was carried out to identify the normal modes in the frequency range of interest. The piezo stack was simulated by a ROD element and its effect numerically characterized. The upper and lower faces of the stack were mechanically coupled with the bracket structure, whereas the active control strategy involved the relative displacement of two opposite points of the bracket. To this aim, dedicated interfaces were designed to integrate the stack into the mounting bracket. In order to control the vibrations in correspondence of the second bending mode (1599.4Hz), the primary disturbance, simulated by a shaker, was modelled in the frequency domain using a white noise signal. A narrow window of 20Hz was initially selected as the control system domain. Then, this frequency range has been made gradually wider around the resonance peak, in order to optimize the control effect, and then extended up to 80 Hz when undesired effects occurred. Primary and secondary control plants were firstly numerically fitted from the measured responses and excitations using system identification techniques, and then used for the active controller design and simulations.

Decoupled Integral LQR Controller with Anti-windup Compensator for MIMO Two Rotor Aerodynamical System (TRAS)

This paper employs a design of two sub-controllers based on Linear Quadratic Regulator (LQR) for Two Rotor Aero-dynamical System (TRAS) in two degree of freedom (2-DOF) motion. Two Rotor Aero-dynamical System (TRAS) is a nonlinear multi-input multi-output (MIMO) system with strong cross coupling. The main focus of the research work is to control both the horizontal and vertical angles of the system so that the desired trajectory is tracked while rejecting disturbances. In this work, TRAS is decoupled into two subsystems (horizontal and vertical) and the derivation of the linear model of each subsystem is developed using Jacobean linearisation matrix. Optimal LQR controller is designed and tuned using Particle Swarm Optimisation (PSO) algorithm for each subsystem. The designed sub-LQR controllers are combined with integral action gain, full state observe and an anti-integral windup based on back-calculation technique. Simulation results show that the decoupled integral LQR controller (DILQRC) exhibits a better performance in terms of transient and steady state responses with significant reduction of settling time, overshoot percentage and error index it also requires less and smooth control signal in case of tracking a step input as compared to the cross coupled PID controller (CCPIDC). Furthermore, a successful experimental validation is demonstrated to emphasise the effectiveness of the proposed control method. Key–Words: Two Rotor Aerodynamical System (TRAS), Linear Quadratic Regulator (LQR), integral action gain, Particle Swarm Optimisation (PSO), full state observer, anti-windup, back-calculation.
Adaptive change in protective coloration in adult striated shieldbugs Graphosoma lineatum (Heteroptera: Pentatomidae): test of detectability of two colour forms by avian predators

1. Protective coloration in insects may be aposematic or cryptic, and some species change defensive strategy between instars. In Sweden, the adult striated shieldbugs Graphosoma lineatum (Heteroptera: Pentatomidae) undergo a seasonal colour change from pale brown and black striation in the pre‐hibernating adults, to red and black striation in the same post‐hibernating individuals. To the human eye the pre‐hibernating adults appear cryptic against the withered late summer vegetation, whereas the red and black post‐hibernating adults appear aposematic. This suggests a possibility of a functional colour change. However, what is cryptic to the human eye is not necessarily cryptic to a potential predator.
The structure of k-Lucas cubes

Fibonacci cubes and Lucas cubes have been studied as alternatives for the classical hypercube topology for interconnection networks. These families of graphs have interesting graph theoretic and enumerative properties. Among the many generalization of Fibonacci cubes are k-Fibonacci cubes, which have the same number of vertices as Fibonacci cubes, but the edge sets determined by a parameter k. In this work, we consider k-Lucas cubes, which are obtained as subgraphs of k-Fibonacci cubes in the same way that Lucas cubes are obtained from Fibonacci cubes. We obtain a useful decomposition property of k-Lucas cubes which allows for the calculation of basic graph theoretic properties of this class, such as the number of edges, the average degree of a vertex, the number of hypercubes they contain, the diameter and the radius.
IS DIATOM DIVERSITY DRIVEN BY PRODUCTIVITY IN BOREAL STREAMS?

The effect of productivity on the diversity patterns has attracted ecologists especially during the last decades. Recent reviews have suggested that the productivity-diversity relationship (PDR) is typically either positive linear or unimodal. The emerged form of the PDR is often affected by the spatial scale and it has been suggested that the relationship is ranging from unimodal at local scales to positive linear at regional scales because of regional complementarity. The aim of this study was to examine the PDR at two spatial scales for stream diatoms. The relationships between total P supply and species richness ranged from a significant negative relationship to a non-significant positive relationship within the studied regions. Across the regions, the relationship between mean total P of the region and regional species richness was unimodal, albeit non-significant. The data showed that the PDR exhibited large variability among the regions and across different spatial scales for stream diatoms. This indicated that diatom diversity was largely driven by other factors than nutrient supply in these streams. The present results also highlight the importance of gradient length in productivity for PDR and lend at least partial support to the pattern accumulation hypothesis because at high nutrient supply, diversity tended to decrease.
Peptides in Musts and Wines. Changes during the Manufacture of Cavas (Sparkling Wines)

The aim of this work was to increase the knowledge of the peptide fraction in musts and wines, of which there are very few publications in literature. For this purpose, the peptides in four varietal sparkling wines manufactured industrially following the Champenoise method were analyzed by HPLC. Samples of the musts, base wines, and sparkling wines were taken after 9, 12, 15, and 18 months of aging on yeast lees. The peptides of the fractions with molecular weights higher and lower than 700, obtained by fractionation on Sephadex G-10, were separated by reversed-phase HPLC. The chromatographic profiles of the peptides in the wines were similar. During the manufacture of the base wines, there was an increase in the peptides studied. During aging, peptides were released and then degraded by the yeast enzymes. Keywords: Peptides; HPLC; must; wine; sparkling wine; cava
On the identity of orchid populations: a morphometric study of the Dactylorhiza traunsteineri complex in eastern Sweden

Dactylorhiza traunsteineri sensu lato is a highly variable, tetraploid aggregate of narrow-leaved marsh orchids with a poorly known distribution. The uncertain distribution is due to difficulties in identifying populations, especially in marginal areas. Populations from calcareous fens in the eastern parts of Sweden were analysed. Predictions concerning morphological differentiation and population structure were tested with multivariate discriminant analyses and by comparing individuals within populations in terms of diagnostic characters. Four possible taxa were considered: D. russowii, D. traunsteineri, D. traunsteineri spp. pycnantha and the variety pusilla. It was concluded that all populations investigated in eastern Sweden belong to one variable taxon, D. traunsteineri.
EFFECTIVE MINER OF TIME-VARIANT DATA USING WEIGHT FACTOR

There are so many important results toward finding the association rules. But, when we consider the sale of seasonal items then no algorithm existed till now that can able to mine the interesting pattern on time– variant seasonal database. In view of this, we propose an Effective Miner (abbreviatedly as EM) algorithm to perform the mining for this problem as well as I conduct the corresponding performance studies. Furthermore, without fully considering the time-changing characteristics of items and transactions, it is noted that some discovered rules may be expired from user’s interest i.e rules generated in one season can not give the useful information in other season. Under EM we first partition the database on the bases of season i.e Yearly, Half Yearly or Quarterly etc according to user’s requirements and then we apply weighted mining on each partition. In EM (Effective Miner) the cumulative information of mining previous partitions is selectively carried over toward the generation of candidate itemsets for the subsequent partitions I have also applied scan reduction technique in EM due to that only two scan of database are required, means saving lots of time.
MIGRATION AND CLUSTERING PHENOLOGY OF DANAUS PLEXIPPUS (L.) (LEPIDOPTERA: NYMPHALIDAE) IN AUSTRALIA

The relationship between temperature and migration of wanderer butterflies Danaus plexippus congregating at a site near Sydney, N.S. W. was studied in 1981 and 1982. Warm (>20°C), sunny days with cold (<10°C) nights during autumn were associated with substantial migratory activity. Migration decreased when nights were mild (>10°C) and ceased in late autumn or early winter when days were cool (<20°C) and nights were cool‐mild. In these conditions formation of stable overwintering populations occurred. Dispersal of wanderer clusters in mid‐late winter did not appear to be correlated with climate.
Powdery mildew (Leveillula taurica) on greenhouse and field peppers in Ontario – host range, cultivar response and disease management strategies

Abstract Leveillula taurica was observed on field pepper at various sites in south-western Ontario in 2005–2007. The field isolates collected from these sites were similar to a greenhouse isolate based on morphological observations. Host range of greenhouse and field isolates was similar, with minor sporulation on potato, carrot and several weeds. The greenhouse pepper cultivar ‘Samanta’ was the most susceptible to L. taurica while ‘Triple 4’, ‘Duplo’ and ‘Bosanova’ were the least susceptible to infection. Best control of pepper powdery mildew in the greenhouse was obtained with applications of myclobutanil, triflumizole, pyraclostrobin + boscalid, quinoxyfen, strobilurin derivatives (azoxystrobin, trifloxystrobin, kresoxim-methyl), copper soap, JMS Stylet-Oil®, Valent-10118, acibenzolar-S-methyl and sulphur. Disease reduction was also obtained with applications of potassium bicarbonate, citrus oil + borax, Bacillus subtilis and a fermented milk byproduct + surfactant. K2HPO4 + surfactant was effective in reducing disease whereas CaCl2 + surfactant, fumed silica and Sporothrix flocculosa were not effective. In field plots, best disease control was achieved with applications of myclobutanil and the fermented milk byproduct + surfactant in 2006 whereas in 2007, citrus oil + borax and potassium bicarbonate were most effective. There were no significant differences in pepper yield among the treatments in field plots. In vitro survival studies showed that the fungus was able to survive in infected pepper leaves after exposure to temperatures of −10 °C for 2 months.
Integrating Multimodal Information in Large Pretrained Transformers

Recent Transformer-based contextual word representations, including BERT and XLNet, have shown state-of-the-art performance in multiple disciplines within NLP. Fine-tuning the trained contextual models on task-specific datasets has been the key to achieving superior performance downstream. While fine-tuning these pre-trained models is straightforward for lexical applications (applications with only language modality), it is not trivial for multimodal language (a growing area in NLP focused on modeling face-to-face communication). More specifically, this is due to the fact that pre-trained models don’t have the necessary components to accept two extra modalities of vision and acoustic. In this paper, we proposed an attachment to BERT and XLNet called Multimodal Adaptation Gate (MAG). MAG allows BERT and XLNet to accept multimodal nonverbal data during fine-tuning. It does so by generating a shift to internal representation of BERT and XLNet; a shift that is conditioned on the visual and acoustic modalities. In our experiments, we study the commonly used CMU-MOSI and CMU-MOSEI datasets for multimodal sentiment analysis. Fine-tuning MAG-BERT and MAG-XLNet significantly boosts the sentiment analysis performance over previous baselines as well as language-only fine-tuning of BERT and XLNet. On the CMU-MOSI dataset, MAG-XLNet achieves human-level multimodal sentiment analysis performance for the first time in the NLP community.
FE SOLUTIONS OF NEAR-TIP FIELD FOR MODE-I CRACKS WITH RESIDUAL SURFACE TENSION

This paper presents finite element solutions of a near-tip elastic field of a straight, nano-scale crack in a two-dimensional, linear elastic, whole plane subjected to mode-I crack-face loads. The mathematical model is formulated using a continuum-based theory of classical linear elasticity together with Gurtin-Murdoch surface model to capture the role of the residual surface tension present on the crack-face material layer. The formulation finally yields a second-order, integrodifferential equation governing the crack opening displacement. A weighted residual technique along with the regularization procedure is applied to establish a weakly singular weak-form equation with the involved kernel of (ln ) r O . Galerkin strategy and the finite element procedure are then employed to discretize the weak-form equation. Various types of element shape functions, generated by standard 0 C -elements, standard 1 C -elements, and special elements with built-in crack-tip functions, are considered. A proper quadrature rule is selected to efficiently and accurately evaluate both nearly and weakly singular double line integrals over pairs of elements resulting from the discretization and the solution of a dense system of linear algebraic equations is obtained using an efficient indirect solver. The rate of convergence of finite element solutions is fully investigated and such information is then used to conclude the influence of the residual surface tension on the behavior of the near-tip field.
