Methods of Reducing Anxiety and Their Relationship with the Age of Patients with Polycystic Ovary Syndrome

Background: Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with clinical manifestations such ashirsutism, acne, reduced fertility, menstrual and obesity disorders, and psychological and mood problems. Anxiety is an unpleasant feeling that has been identified through several ways. We assessed the approaches to reducing anxiety and their association with the age of patients suffering from PCOS.Methods: This is a descriptive cross-sectional study on the methods for reducing anxiety and the relationship between the type of method and patients’age. Through the use of a checklist, we examined 80 women of childbearing age with PCOS. Chi-square test was used to analyze the data, and 5% level was considered as the significant level.Results: Based on the results obtained 45 subjects (56.2%) reduced their anxiety through prayer and religious deeds, 30 (37.50%) by crying, 27 (33.8%) by listening to music, 12 (15%) through fighting, and nine (11.25%) by sleeping. Seven participants (8.75%)did yoga and exercised, and 21 (26.25%) used other methods to reduce their anxiety. There was also a significant relationship between people’s age and prayer (P=0.038). Also, people’s age and listening to music (P=0.043) were observed to decreaseanxiety and in other cases, no significant relationship was observed.Conclusion: The most common strategy for reducing anxiety among patients was to pray and perform religious deedsalong with other methods. There was also a significant association between the participants’ age and praying and listening to music as waysof lowering anxiety.
Does Costly Persuasion Signal Quality?

This article investigates how a privately-informed seller could signal her type by gathering information about the buyer's match value. We study two alternative ways to obtain information. In the first one, labeled information acquisition, the seller can acquire exogenous signals by facing a fixed acquisition cost. In the second one, on top of the fixed cost, the seller faces an additional designing cost based on mutual information to endogenously reduce uncertainty on the match value (information design). At first glance, bearing such cost may seem not convenient for the seller. However, we show that when the designing cost is relatively high, the parameter region in which separation can occur is larger under information design. When this cost is low, the separation cannot emerge under information design. The non-monotone relationship between the designing cost and separating outcomes shows that a seller's ability to provide match information is not necessarily associated with more precise quality information.
Syntheses of New Gramicidin A Derivatives

Gramicidin A was covalently coupled with theophylline, thyroxine, digoxigenin, and biotin. New compounds were synthesized when the four molecules were coupled to ethanolamine on the C-terminus of gramicidin. Peptidic linkers were inserted between gramicidin and the bio-molecules.
Role Workflow Model Applied to Multi Node Fog Computing System

A role task scheduling method for fog computing system based on behavior flow is proposed. As traditional computing has shift from face data to the edge of the distributed computing, task scheduling method by establishing the role behavior flow system, the role of the resource node cooperation behaviors definition and role of organization behavior, and set up from center to edge the role behavior of flow pattern, enables the compute nodes according to their respective role behavior line classification processing. Therefore, it can effectively solve the problems of slow service response, high power consumption and frequent task interruption caused by large data volume and redundant operation in the traditional cloud computing system.
Novel Homo- and Heterobimetallic Palladium(0) and Platinum(0) Complexes of Olefinic Mono-, Bis-, and Tris-macrocyclic Ligands

Molecular structures featuring two and three triolefinic 15-membered macrocycles of type 2 as well as their homo- and heterometallic complexes of palladium(0) and platinum(0) (5, 7) have been synthesized from 2,4,6-trichloro-1,3,5-triazine, 1. The strategy employed allows easy preparation of heterobimetallic complexes in a controlled manner. Several mass spectrometry techniques are useful to identify these complexes.
Depletion-Induced Phase Separation of Aggregated Whey Protein Colloids by an Exocellular Polysaccharide

An attractive interaction, commonly referred to as depletion interaction, is induced between aggregated whey protein colloid (AWC) particles when they are mixed with exocellular polysaccharides (EPSs) from a lactic acid bacterium. This interaction originates from a loss of conformational entropy of the EPSs near the surfaces of neighboring AWC particles and leads to a phase separation at high enough EPS and AWC concentrations. The effect of the depletion interaction on the properties of the mixtures of EPS and AWC particles is first studied in the stable, that is, one-phase, region. Small-angle neutron scattering (SANS) and dynamic light scattering (DLS) were used to characterize the strength of attractions. The SANS results can be described quantitatively by a model for depletion interaction. From Ornstein−Zernike plots, we derive the position of the spinodal. The DLS results can be described qualitatively quite well by using a recently derived expression for the wavevector (Q)-dependent diffusion coeffi.
Microencapsulation of Kaffir Lime Oil and Its Functional Properties

This paper describes the effects of spray drying temperature and wall materials on functional properties of kaffir lime oil microcapsules. The effects of spray drying were studied at inlet air temperatures at 160, 180, and 200°C. Two coating materials (konjac glucomannan and gum arabic) were employed in this study. The results indicate that kaffir lime oil had antibacterial activity against all tested pathogens and was able to inhibit Vibrio cholerae comparable to a standard antibiotic. The combination of konjac glucomannan and gum arabic (KGM+GA) can enhance the yield and retention of total oil in the microcapsules more than using konjac glucomannan alone as a wall material. Increasing inlet air temperature resulted in a decrease of antibacterial activity and amount of bioactive volatile compounds. Physical and chemical properties of the microcapsules did not differ significantly (p > 0.05) in terms of process yield, a w , moisture content, efficiency in retention of total, surface and inner oil, water solubility index, and color except at inlet air temperature of 200°C. However, it was found that the kaffir lime oil microcapsules from KGM+GA produced at inlet temperature of 180°C had the best functional properties in terms of antibacterial activity and efficiency of retention of total encapsulated oil.
Soil losses due to potato harvesting at the regional scale in Belgium

During harvesting of crops, such as sugar beet, potatoes and chicory roots, considerable quantities of soil, consisting of adhering soil, soil clods and stones, are exported from cropland. This soil erosion process is called soil loss due to crop harvesting (SLCH). This study aimed to assess the variability in soil losses caused by potato (Solanum tuberosum L.) harvesting in Belgium and to investigate the role of weather conditions prior to the harvest and regional differences in soil texture on SLCH variability. To meet these objectives, more than 1000 soil tare data measured at a potato‐processing factory during the harvesting seasons of 1999, 2000 and 2001 were analysed. Soil loss was on an average 2.2 t ha−1 per harvest but could be as large as 45 t ha−1 per harvest. The average soil losses per municipality were positively and exponentially related to the average content of soil particles <16 μm. This relationship was in close agreement with a previous field study on SLCH for potatoes in Belgium and could explain why measured soil loss values from a German study were larger than SLCH values for potatoes measured in Belgium. Weather conditions prior to harvest played only a minor role for SLCH variability. As a consequence, SLCH for potatoes harvested mechanically is more variable in space than in time.
Selecting the Optimal Use of the Geothermal Energy Produced with a Deep Borehole Heat Exchanger: Exergy Performance

The geothermal sector has a strength point with respect to other renewable energy sources: the availability of a wide range of both thermal and power applications depending on the source temperature. Several researches have been focused on the possibility to produce geothermal energy without brine extraction, by means of a deep borehole heat exchanger. This solution may be the key to increase the social acceptance, to reduce the environmental impact of geothermal projects, and to exploit unconventional geothermal systems, where the extraction of brine is technically complex. In this work, exergy efficiency has been used to investigate the best utilization strategy downstream of the deep borehole heat exchanger. Five configurations have been analyzed: a district heating plant, an absorption cooling plant, an organic Rankine cycle, a cascade system composed of district heat and absorption chiller, and a cascade system composed of the organic Rankine plant. District heating results in a promising and robust solution: it ensures high energy capacities per well depth and high exergy efficiency. Power production shows performances in line with typical geothermal binary plants, but the system capacity per well depth is low and the complexity increases both irreversibilities and sensibility to operative and source conditions.
Structure-activity Relationship Model for Predicting the Hallucinogenic Activity of Phenylalkylamines

A Quantitative Structure-activity Relationship(QSAR) model was developed to predict the hallucinogenic activity of phenylalkylamines by Artificial Neural Network(ANN) method.Each compound was represented by the calculated structural descriptors involving constitutional,topological,geometrical,electrostatic and quantum-chemical features of compound.The ANN method produced a nonlinear and seven-descriptor QSAR model with a standard error S = 0.0128 and a correlation coefficient R = 0.9752. The electronic properties of 75 phenylalkylamines were calculated with Gaussian 03 program at the DFT/B3LYP/6-311+G(d,p) level.The quantum chemical analyses were performed from two aspects of frontier molecular orbital and charge distribution.The results show that seven structural describers are crucial to the hallucinogenic activity of phenylalkylamines and that the para-and ortho-positions could be active sites acting as electron donors.
Aerosol OT Microemulsions as Carriers for Transdermal Delivery of Hydrophobic and Hydrophilic Local Anesthetics

The skin permeation enhancement of many kinds of drugs and cosmetic substances by microemulsions has been widely known; however, the correlations between microemulsion microstructures and the efficiency of skin permeation are not fully elucidated. Therefore, the aim of our study was to investigate the influence of microemulsion types on in vitro skin permeation of model hydrophobic drugs and their hydrophilic salts. The microemulsion systems were composed of isopropyl palmitate (IPP), water, a 2:1 w/w mixture of Aerosol OT (AOT) and 1-butanol, and a model drug. The concentrations of surfactant mixture and model drug were maintained at 45% and 1% w/w, respectively. The concentrations of IPP and water were 15% and 39% w/w, respectively, for oil-in-water (o/w) type and vice versa for water-in-oil (w/o) type. The samples were prepared by simple mixing and characterized by visual appearance, pH, refractive index, electrical conductivity, viscosity, and determination of the state of water and IPP in the formulations using differential scanning calorimetry. Transdermal flux of lidocaine, tetracaine, dibucaine, and their respective hydrochloride salts from the drug-loaded AOT-based microemulsions through heat-separated human epidermis was investigated in vitro using modified Franz diffusion cells. The o/w microemulsions resulted in the highest fluxes of the model drugs in base form as compared with the other formulations within the same group of drugs. Moreover, the skin permeation of drug from microemulsions depended on drug molecular structure and interaction between drug and surfactant.

National Curriculum for English in Pakistan, reveals its intentions for acquiring language related international requirements concerning with career choices and furthering education. Formative assessment is at the center of students’ learning and is devised in the curriculum document providing basis for its implementation. Curriculum implementation is pivotal to classroom practices of teachers. Curriculum guides teachers to implement formative assessment. Professional commitment contributes enriching teacher’ classroom practices. Focus of the study was to examine formative assessment practices of teachers, as a part of curriculum implementation, in accordance with curriculum document and its relationship with professional commitment of secondary school English teachers. Study secures its significance for teachers, curriculum developers, and governmental agencies. Quantitative survey was the method adopted for the study and explanatory correlational design was used. Teachers, concerned with teaching of English at secondary level, from entire secondary schools working under the supervision of the Punjab province were the study population. Sampling procedure employed multistage stratified random sampling technique and 576 teachers were selected as study sample. Two questionnaires were developed that included questionnaire regarding implementation of formative assessment (QIFA) and teachers’ professional commitment scale (TPCS). Survey was conducted as a data collection strategy. In statistics, Mean and Spearman correlation were employed. Results revealed that professional commitment of teachers and their formative assessment practices were moderate. Results regarding relationship between the variables; professional commitment of teachers and their formative assessment practices were significant correlated. The study recommended school based teacher trainings to sensitize and enhance teachers’ awareness and practices towards formative assessment practices as a part of implementation process. Governmental agencies are needed to focus the situation of professional commitment of teachers and implementation of formative assessment as a part of implementation.
Wideband Substrate Integrated Waveguide Bandpass Filter Based on 3-D ICs

This paper proposes a substrate integrated waveguide bandpass filter (SIW BPF), exploiting the through-dielectric via (TDV)-based 3-D integrated circuit (3-D IC) technology. The SIW BPF is designed on the dielectric cavity that is etched on the traditional low-resistivity silicon (LRSi) in a 3-D IC system, acting as the insulating material between through-silicon via plugs and LRSi. This construction can reduce prominent eddy current losses in LRSi and coupling losses among TDV plugs for the millimeter-wave application. Benzocyclobutene and glass are chosen as the dielectric cavity due to the low dielectric constant and loss tangent. The detailed design procedure beginning from the normalized Chebyshev low-pass filter to the final optimized SIW BPF is presented. The filter having a 12.5% fractional bandwidth is centered at 159.67 GHz. The return losses and insertion loss across the passband are about −10 and −1.5 dB, respectively. Numerical analysis of the advanced design system and full-wave simulation results of Ansoft’s HFSS show a good agreement.
Key Technique of Almost Exact Simulation for Non-affine Heston Model

In order to sample asset price more accurately under the non-affine Heston model in the situation where the Feller condition was unsatisfied, we proposed the key technique of almost exact simulation for non-affine Heston model, by fusing the approximate analytic solution of conditional variance characteristic function, the second-order Newton’s method and interpolation method. Numerical results on four representative benchmarks show that our newly proposed simulation scheme has both good convergence and accuracy, which are much better than those of the Itô-Taylor schemes. Especially, our scheme performs well in the case where the Feller condition is extremely unsatisfied, while the alternatives don’t work.
Mechanism of the Electrorheological Effect: Evidence from the Conductive, Dielectric, and Surface Characteristics of Water-Free Electrorheological Fluids

The conductive, dielectric, and surface properties of several water-free polymer or inorganic material based ER fluids, as well as their response times, are investigated to elucidate the physical ground of the electrorheological (ER) effect. It is found that the slow polarization, especially the interfacial polarization rather than the Debye polarization, might be responsible for the observed phenomena. A possible ER mechanism is proposed as follows: a large interfacial polarization would facilitate the particle to attain a large amount of charges on the surface, then leading to the turn of particle along the direction of an electric field to form a fibrillation structure; the strength of fibrillation chains is thus determined by the particle polarization force, i.e., the particle dielectric constant. The rationality that the marked interfacial polarization would likely drive the particles to turn is theoretically addressed on the basis of experimental results.
Novel Approaches to Enhance Oral Bioavailability of Poorly Soluble Drugs

Oral administration is considered as major, convenient route among all other routes of delivery, owing to several benefits. But, the poor solubility or enzymatic/metabolic activity are the major concerns in developing a successful formulation. About 40% of approved drugs which are in the current market and 90% of new drug molecules in the developmental pipeline are hydrophobic in nature. The challenge to formulate insoluble drugs has met with various approaches to overcome the problems related to solubility, application of nanotechnology is one amongst them. The present review deals with various nanocarriers and technologies that are proven to be effective in enhancing the bioavilability of poorly soluble drugs.
Research on vehicle camera calibration and ranging technology based on texture features

In order to realize the ranging function of the vehicle monocular camera on unstructured roads, it is proposed to use the method based on texture features and soft voting to detect the vanishing point of the road and the road edge, and use camera calibration method and tri-linear method to obtain the internal and external parameters of the camera. Obtain the distance information in the image according to the geometric relationship model. Experiments show that this method can measure the distance of an unstructured road image with only the centerline of the road relying only on the vehicle monocular camera. The method has a wider application range and is simpler in actual engineering.
Aging of HTPB/AP‐based composite solid propellants, depending on the NCO/OH and triol/diol ratios

Aging behavior of hydroxyl-terminated polybutadiene/ammonium perchlorate (HTPB/AP)-based composite solid propellants was studied as a function of crosslink density, which is predominantly determined by the molar ratio of diisocyanate to total hydroxyl (NCO/OH ratio) and the molar ratio of triol to diol (triol/diol ratio). For this purpose, 16 propellant samples with different compositions were prepared by changing the NCO/OH ratio as 0.81, 0.82, 0.83, and 0.85 for each triol/diol ratio of 0.07, 0.09, 0.11, and 0.13, and subjected to an accelerated aging at 65°C. The changes in the mechanical properties were monitored throughout the aging period. In the initial part of the aging period, a sharp increase in stress, modulus, and hardness values and a sharp decrease in strain values were observed for all the propellants. At further stages of aging, only slight changes were observed in the mechanical properties. Concerning the aging criterion as reduction in the strain capability more than the half of the initial value, the propellants with respective NCO/OH-triol/diol ratios of 0.81–0.09, 0.85–0.09, 0.81–0.13, 0.83–0.13, and 0.85–0.13 can be considered to be aged with time. © 2000 John Wiley & Sons, Inc.

Forces Measured between Latex Spheres in Aqueous Electrolyte: Non-DLVO Behavior and Sensitivity to Dissolved Gas

An atomic force microscope was used to measure the forces acting between two polystyrene latex spheres in aqueous media. The results show an electrostatic repulsion at large separations which is overtaken by an attractive “hook” that pulls the two spheres into contact from a considerable range (20−400 nm), much larger than could be expected for a van der Waals attraction. The range of operation of this attraction varies from one experiment to another and is not correlated with electrolyte concentration. However, the range is found to decrease significantly when the level of dissolved gas in the water is reduced.
A density functional theory study of carbon monoxide adsorption on platinum-doped gold clusters

An all-electron scalar relativistic (AER) calculation on Au n PtCO ( n = 1–12) clusters had been performed using density functional theory (DFT) with the generalized gradient approximation (GGA) at Perdew-Wang 91 (PW91) exchange-correlation functional level. The CO molecule prefers to be adsorbed on Pt in Au n Pt ( n = 1–12) clusters. The introduction of impurity Pt strengthens the adsorption toward CO molecule and then promotes the reactivity enhancement of CO molecule. The CO molecule is also more favorable to be adsorbed by the even-numbered Au n Pt clusters with closed-shell electronic structure.
