On the Static Pull-In of Tilting Actuation in Electromagnetically Levitating Hybrid Micro-Actuator: Theory and Experiment

This work presents the results of the experimental and theoretical study of the static pull-in of tilting actuation executed by a hybrid levitation micro-actuator (HLMA) based on the combination of inductive levitation and electrostatic actuation. A semi-analytical model to study such a pull-in phenomenon is developed, for the first time, as a result of using the qualitative technique based on the Lagrangian approach to analyze inductive contactless suspensions and a recent progress in the calculation of mutual inductance and force between two circular filaments. The obtained non-linear model, accounting for two degrees of freedom of the actuator, allows us to predict accurately the static pull-in displacement and voltage. The results of modeling were verified experimentally and agree well with measurements.
The era of Instagram expansion: matching social media marketing activities and brand loyalty through customer relationship quality

ABSTRACT The social media revolution has massively transformed marketing plans and practices in the business world. Moreover, marketers can reinforce customer–brand relationships through companies’ social media marketing (SMM) plans and gain a clear understanding of the consumer perspective more quickly than ever before. Using the stimulus–organism–response (SOR) framework, this study developed a model to examine how SMM activities (SMMAs) affect dimensions of customer relationship quality (CRQ) – that is, commitment, trust, and satisfaction – and brand loyalty (BL). This study, which investigated the dimensions of CRQ as mediation effects between SMMAs and BL to telecommunications brands on Instagram, adopted structural equation modeling and obtained data from a sample of 290 Instagram users in Palestine who are telecommunications customers. The findings show that SMMAs positively affect the dimensions of CRQ and that SMMAs are a stronger predictor of commitment than trust and satisfaction. Additionally, SMMAs had a positive effect on BL. The results confirmed the significant effect of three components of CRQ on BL building. The results also revealed that dimensions of CRQ act as mediators between SMMAs and BL. The study contributes to the literature by examining the underlying mechanism of how SMMAs promote dimensions of CRQ and BL in the service industry.

On the number of solutions of a class of nonlinear resistive circuits

The author deals with the number of solutions of equations of nonlinear resistive circuits composed of linear and nonlinear one-port resistors, linear active elements, and DC sources. By referring to the V-I characteristics of real diodes it is assumed that the second derivative as well as the first derivative of the V-I characteristics of nonlinear resistors are positive. The necessary and sufficient conditions are given for the equation to have a finite number (<or=2/sup n/) of solutions. The extension of this result is discussed. <<ETX>>
Investigation of the Influence of Sprinkler Fins and Dissolved Air on Jet Flow

Experimental investigations of an irrigation gun water jet revealed that the flow is a mixture due to the degassing of the air dissolved in the supply water. The expansion of resulting air bubbles allowed velocity measurements in the region of the free jet close to the nozzle by a nonintrusive method (particle image velocimetry). Additional measurements were also implemented with an intrusive double-tip optical fiber probe. In this study a comparison was undertaken on the dynamic parameters of the outflow from a gun with fins and a second unfinned. Results underline the effects of fins and degassing on the jet internal properties and their consequences on the irrigation process.
Dietary inclusion of Schizochytrium limacinum meal can maintain key productive parameters of pink cusk-eel (Genypterus blacodes) juveniles with a reduction in fish oil

The pink cusk-eel ( Genypterus blacodes ) is a promising new candidate species to diversify cold-water aquaculture further. However, there are several knowledge gaps to establish a commercial-scale cultivation strategy, with optimum feed formulation being one of the main remaining challenges. This study aimed to assess the dietary inclusion of Schizochytrium limacinum heterotrophic microalgae meal as a sustainable source of docosahexaenoic acid on fish growth and the condition status of pink cusk-eel juveniles. Three extruded diets were formulated to contain 0, 5 and 10% of dried algae and fed to duplicate groups of fish twice daily until apparent satiation during the 12-week trial. On termination of the feeding trial period, the average live weight gain did not show statistically significant differences between the three groups of juvenile fish, achieving an increase in weight of about two times at the end of the trial. Similarly, the protein efficiency and feed conversion ratios did not show significant differences among the experimental diets. On the contrary, a significant reduction in feed intake was observed as the dietary inclusion of microalgae meal increased. These results indicate that S. limacinum meal is a sustainable alternative ingredient for the dietary substitution of fish oil in commercial feed for G. blacodes at limited inclusion.
An On-Road Study of Head-Up Display

The purpose of this study was to gain a better understanding of driver’s perceptions of Head-Up Displays (HUD). Many HUD studies have been conducted but few have allowed drivers to test a HUD in their own vehicle, allowing them to choose the best HUD location for themselves. Forty participants drove their own vehicles using a portable HUD device, testing different HUD locations, and then rated the HUD using the Technology Acceptance Model. The results showed that the HUD was rated as easy to use and the drivers intended to use it in continuation. The drivers wanted the HUD to be located outside of the traffic scene, below their line of sight. These results give support for new HUD locations and for increased HUD implementation.
Optical mapping of the Fusarium oxysporum f. sp. melongenae genome

Optical mapping approaches are widely preferred and applied in different branches of genomic studies because of their accuracy, low cost, and high efficiency. In the current study, a sequence orientation of the Fusarium oxysporum f. sp. melongenae (FOMG) genome that is deposited in GenBank National Center for Biotechnology Information under accession number MPIL00000000 was used as the reference genome, which we checked with Bionano Genomics optical mapping approaches. The optical mapping produced 103 contigs, the longest of which was 3.05 Mb. The N50 value of optical map contigs is 0.85 Mb. The sequences of the FOMG reference genome and optical map mainly match each other. Results obtained in the current study indicate that optical mapping can be used to construct complete and gapless assemblies of the FOMG genome. It also can be applied to validate a previous genome assembly.
Fire Hazard Assessment of Polypropylene Wall Linings Subjected to Small Ignition Sources

The fire hazards associated with polypropylene wall linings sub jected to small ignition sources, were evaluated using large scale experiments and cone calorimetry. A series of seven ignition sources with increasing sever ity as recommended in BS 5852 were used in the tests. The results obtained in dicate that ignition of the polypropylene linings is likely when exposed to igni tion sources 5 to 7 as defined in BS 5852. It was observed that the melting behaviour of the polypropylene wall linings significantly affected the burning behaviour. A pool fire, consisting of melted polymer, formed at the base of the wall which then controlled the fire growth processes. The rate of flame spread on the lining surface which depended on the growth of the pool fire was slow because the thin polymer sheet could only supply a limited amount of melted polymer to the pool. The estimated heat release rates from the pool fire were close to the values measured in the cone calorimeter at the heat flux level of 25 kW m-2.
Has the risk of a 1976 north‐west European summer drought and heatwave event increased since the 1970s because of climate change?

In the summer of 1976, north‐west Europe experienced an exceptional heatwave and drought, which impacted agriculture and public water supply. This study aims to assess how the likelihood of the event in the present‐day climate has changed since 1976 because of climate change. The analysis focuses on the England and Wales region, which was particularly badly impacted. Three key factors contributing to the extreme summer were identified: the dry preceding winter–spring period, the dry summer and the hot summer. Following the principles of event attribution, three methods are used to evaluate the change in event risk: one using observational data, a second using CMIP5 coupled climate models and a third using HadGEM3‐A atmosphere‐only simulations. This is the first time that this method has been used to evaluate how the risk of a historical extreme event has changed since it originally occurred. The results from the three methods agree qualitatively. The probability of a summer at least as hot as 1976 has increased significantly between the 1970s and the present‐day climate (estimated risk ratios 11 (5–95% confidence interval (CI) [7,14]), 9 (CI [4,28]) and 19 (CI [5,25]) based on the three respective methods). In contrast, no significant change in the probability of an extreme dry winter–spring or an extreme dry summer was found. However, the joint probability of an extreme dry winter–spring followed by an extreme hot summer and the probability of an extreme hot and dry summer have both increased significantly between the 1970s and the present day (estimated risk ratios between 5 and 79, and between 3 and 39, respectively). Water resource systems should therefore be robust enough to cope with more frequent occurrences of summers as extreme as 1976.
The Use of Olive Leaves in Buža Olive Cultivar Oil Production: Exploring the Impact on Oil Yield and Chemical Composition

The effect of the addition of different amounts of olive leaf (1, 2.5, and 5%, m/m) during Buža olive cv. oil production on the quantitative production parameters, composition, and sensory characteristics of the obtained oils were investigated in this study. The addition of leaf during oil extraction increased oil yield and extractability index by 97% compared to the control oil. The addition of leaf during extraction increased the concentration of pigments in oils, and the oil positive sensory attributes intensities, such as fruitiness and green grass/leaf notes. The influence on oil phenolic composition was dependent on the amount of leaf added. When 1% leaf was added, most of the phenolic compounds were preserved, while the addition of leaf at 5% decreased the concentration of the majority of phenols, especially secoiridoids by 45% compared to the control oil. The addition of leaf slightly increased the concentration of fatty acid ethyl esters and waxes in the oils. The obtained results indicate that particular importance should be given to the amount of olive leaf present in olive paste during oil extraction, since it apparently can increase the extractability of oil, but can also have negative effects on phenolic composition when added in excess.
Evaluation of the effective protection distance of low-voltage SPD to equipment

Installing surge protection devices for a low-voltage power supply is important to ensure the survival of electric or electronic devices and systems. Sometimes one group of surge protective devices (SPDs) installed on the distribution board is expected to protect all equipment supplied power by this distribution board. This equipment is connected to the distribution board by cables with different lengths, the influence of the cable length between the SPD and protected equipment on protective effects of SPD was discussed. The reflection and oscillation phenomena of the transient voltage caused by the connecting cables were analyzed, which would affect the protective effects of SPDs. These phenomena depend on the characteristics of the SPDs, the properties of the protected loads, and the length of the connecting cable. Five different types of loads and three different cable lengths have been simulated by electromagnetic transient analysis software, and their respective transient voltages across the SPD and the load were discussed in detail. The effective protection distances of SPD to equipment were analyzed for different types of loads.
Benefit of Ruesi Dadton on Oxidative Stress and Physical Performance: Quasi-Experimental Study

Abstract This study aimed to investigate the effect of Ruesi Dadton (RD) group exercise on oxidative stress (OS) levels and health conditions in healthy elderly individuals. This quasi-experimental study evaluated 23 healthy elderly participants, with evaluations at baseline, and 4 and 12 weeks after RD program initiation. RD consisted of 15 postures performed three times a week. OS was measured through levels of malondialdehyde (MDA) and 8-hydroxy-2-deoxyguanosine (8-OHdG), and activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT). Blood pressure (BP) and balance were also observed. The results revealed that RD yielded significantly improved balance and CAT activity and decreased MDA level at 4 weeks. At 12 weeks, significant improvements in BP, balance, and SOD, CAT, and GPx activities and decreases in MDA and 8-OHdG levels were observed. These results suggest that RD can improve BP and balance by decreasing OS and increasing antioxidant levels in healthy elderly individuals.
The economic effects of politically connected entrepreneurs on the quality and rate of regional entrepreneurship

ABSTRACT While research on institutional quality and entrepreneurship has consolidated over the last decade, the role that politically connected entrepreneurship (PE) plays in the perception of economic actors about the quality and a rate of entrepreneurial activity in their cities remains unanswered. The origin and nature of PE are heterogeneous, and it is associated with economic activity in a strong formal and informal cooperation with local and national governments to access resources in a privileged way. This study uses primary data from 1729 economics agents surveyed in 17 cities in East and Southeast Europe as well as Balkans and Central Asia. In order to better understand the consequences of PE, one should look at how it moderates the relationship between access to capital for entrepreneurs and the outcomes of entrepreneurial activity. We find that politically connected entrepreneurship may limit access to debt finance by other – non-politically economic actors, in particular in countries with a high level of corruption and market uncertainty. PE does not affect equity capital availability for entrepreneurship. Important policy implications are discussed for developing productive entrepreneurship in cities in emerging and developing economies.
EFFECT OF EXOGENOUS BOVINE SOMATOTROPIN (rbST) ON GROWTH IN KUNDHI BUFFALO CALVES

Recombinant Bovine somatotropin (rbST) is one of the hormones potentially used as a growth promoter in feedlot animals. Present study was conducted on twelve male Kundhi buffalo calves maintained at Livestock experiment station, Faculty of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University Tandojam to evaluate rbST effect on growth. The Calves were randomly divided into three groups i.e. A, B and C, each having four calves (n=4). Group A was kept as control, while group B and C were treated with rbST @ 0.5 mg and 1.0 mg/kg BW fortnightly respectively. The calves were given fattening ration ad libitum for two weeks as adaptation period and eleven weeks for treatment period. The parameters studied were body weight, feed intake, average daily gain (ADG), dry matter intake (DMI) and feed efficiency (FCR). Body weight increased significantly (P<0.05) in group C, followed by group B and A. Feed intake recorded showed significant difference (P<0.05) between rbST treated groups and control group. ADG was significantly increased (P<0.05) in group C and B compared to control group. DMI was recorded also showed significant difference (P<0.05) between rbST treated groups and control group. FCR was significantly improved (P<0.05) in group C and B compared to control group but the difference was non-significant between group B and C. The calves in group C and B were economically better as compared to control group. So, it has been concluded that rbST treatment is better and remarkably effective for increasing the performance of young calves in terms of body weight gain, feed intake and FCR. A dose of 1.0 mg/kg BW is more effective and better in promoting the performance of calves as compared to a dose of 0.5 mg/kg BW.
A Lysimeter Study of the Aerobic Landfill Concept

An investigation was undertaken concerning the enhancement of degradation in a landfill. Degradation can be enhanced by the application of water, the recycling of leachate and the addition of air. A lysimeter study was undertaken to determine the quantities of moisture and air that would optimize degradation. The final concept involved application of moisture levels greater than those usually found in composting, combined with the addition of air forced by blowers. Aerobic operation provided significantly faster rates of degradation. The principal measure was that of settlement. In conclusion, some very preliminary economic considerations are presented.

Parametric Study for Hovering Performance of a Coaxial Rotor Unmanned Aerial Vehicle

This paper proposes a reliable aerodynamics analysis method designed for a coaxial rotor unmanned aerial vehicle. It is then used to investigate the effects of the selected design parameters on the hovering performance of the coaxial rotor. A coaxial rotor performance analysis code based on the source-doublet panel method is developed, and its accuracy is verified to be sufficient by comparing its results to various test data. Through a parametric study for the rotor design parameters, such as radius, twist, and taper, the effect of each parameter on the coaxial rotor design is investigated and a statistical analysis for the resulting data is conducted. The results show that the diameter has the biggest impact on the hovering performance of a coaxial rotor, whereas the taper has the biggest impact if the diameter is fixed. Based on these findings, a revised rotor platform is proposed, with 33 % improvement of the figure of merit over the baseline concept, which implies that the optimal design significantly improves the performance of the rotor under development.
Supply chain information technologies and organisational initiatives: complementary versus independent effects on agility and firm performance

This research investigates the roles of supply chain information technologies (SCIT) and supply chain organisational initiatives (SCOI) in engendering agility and business performance in manufacturing firms. We examine two competing models, both of which incorporate agility as a mediator between the use of SCIT or SCOI and firm performance; the models differ in how the impacts of SCIT and SCOI are manifest. In one model, SCIT and SCOI are hypothesised to have separate effects on agility, which then impacts firm performance; in the second model, complementarities, or the interaction of SCIT and SCOI, impacts agility directly. Structural equation modelling results show that agility is full mediator, related to firm performance in both models. Further, the model with complementary interactions fits better. These results have implications for how manufacturing firms can position their investments in SCIT and SCOI to enhance agility and overall performance.
