Free and Forced Vibration Analysis of H-type and Hybrid Vertical-Axis Wind Turbines

Vertical-axis wind turbines (VAWTs) are compact and efficient and have become increasingly popular for wind energy harvesting. This paper mainly focuses on free and forced vibration analysis of two different types of VAWTs, i.e., an H-type VAWT and a new hybrid VAWT. The H-type VAWT has a lower cost, while the hybrid VAWT has a better self-starting capability at a low wind velocity. Both of them can be used for wind energy harvesting. By using the assumed modes method, the two VAWTs are simplified by a single degree-of-freedom (SDOF) model. By utilizing the method of structural mechanics, a multi-degree-of-freedom (MDOF) model is developed for the two VAWTs and the turbines in them are reasonably simplified. Natural frequency analyses for the SDOF and MDOF models of the two VAWTs are conducted. A beam element model (BEM) of the two VAWTs is created to calculate their natural frequencies and mode shapes and to verify natural frequency results from the SDOF and MDOF models. By using the BEM of the two VAWTs, their amplitude-frequency responses are obtained from harmonic response analysis. To analyze forced vibrations of the two VAWTs, aerodynamic loads on the two VAWTs are obtained from computational fluid dynamics (CFD) simulation. By using solid element models of the two VAWTs, forced transient responses of the two VAWTs are calculated by using the aerodynamic loads from CFD simulation. Steady-state forced response amplitudes of the 1 m-mast hybrid VAWT are 23.8% and 20.5% smaller in X- and Y-directions than those of the 1 m-mast H-type VAWT, respectively. Frequency contents of the aerodynamic loads from CFD simulation are calculated, which confirm that they are periodic, and the power efficiency of the H-type VAWT is about 2.6% higher that of the hybrid VAWT.
Esters of Tartaric Acid, A New Class of Potential “Double Green” Plasticizers

A library of 13 esters and methylated esters, including entirely new molecules, derived from renewable natural tartaric acid, have been synthesized, characterized, and used as plasticizers of polylactide (PLA). Differential scanning calorimetry (DSC) studies of the blends consisting of PLA and tartaric acid derivatives reveal that all esters obtained exhibit plasticizing properties; however, their miscibility with PLA and ability to modify the thermal transition is dependent significantly on the structure of the ester group. It was found that esters bearing short alkyl groups (methyl, ethyl, n-butyl) may act as primary plasticizers that allow blends of elastomeric properties to exist at ambient temperature. The hydrolytic and enzymatic stability of plasticizers has been studied using dimethyl and diethyl tartrate, and both materials can be classified as biodegradable.
Refinement of Passive Nematode Recovery from Cotton Growing High Clay Content Australian Vertisols

ABSTRACT Vertisols are characterized by their high clay content, which can hinder assessment of their soil biology. Recovery of nematodes from vertisols with active techniques has indicated that free living nematode numbers within Australian vertisols are often low. Despite this, cotton yield losses due to the reniform nematode have recently been reported in Australia. In light of this and other changes in the cotton production system, we undertook a series of experiments to determine whether passive nematode extraction techniques could be applied to high clay vertisols. Existing published passive nematode recovery methods proved to be inefficient. The use of sodium hexametaphosphate as a clay dispersant was found to further reduce effectiveness. Instead, direct extraction of soil in Ludox at 1.1 g/cm3 followed by sieving was found to be as effective at recovering nematodes using Baermann funnel extraction from fresh soil but considerably quicker and three times more effective with dried soil.
Transmission Mechanism of Monetary Policy in Nigeria: Investigating the Role of Private Sector Credit

: This study examines the interest rate channel of monetary policy rates through private sector credits to prices. It applies an approach that is not common in monetary policy transmission mechanism in literature as many studies on transmission mechanism of monetary policy only examine statistical relationship between policy variables and target variables which may not be able to explain the pathway through which the monetary policies are transmitted. This paper uses mediation approach to assess the significance of causal path of interest rate through the bank lending channel. This paper dwelt on the transmission paths- from maximum interest rate, inter-bank call rate, treasury bill rate to prices through the private sector credits. The findings of this study lay credence to effective and significant transmission effects of interest rates (maximum lending rate, interbank lending rate and treasury bill rate) through private sector credit to prices. The paper concludes that maximum lending rate path has the highest significant transmission effect to prices. This is followed by the treasury bill rate and the inter-bank call rate respectively . The findings in this study is new in the case of Nigeria as no previous studies have applied mediation approach to the study of transmission mechanism of bank lending channel in Nigeria. Central banks should explore ways to effectively make policy towards effectively directing the monetary policy through maximum lending rate and treasury bill rates as they have the most significant paths through which the monetary policy rate is transmitted to prices. mechanism using information on the country’s main economic objectives as a proxy for bank credit availability; and by using bank’s prices to disentangle loan supply from loan demand shift in the ‘credit channel’ literature. The study provides evidence on the role of banks in the monetary transmission process. The study concludes that credit is an important part of the transmission process of Nigerian Monetary Policy.

Investigation of the manganese stress on wheat plant by attenuated total reflectance Fourier transform infrared spectroscopy

ABSTRACT The present paper deals with the investigation of the changes in chemical contents of the leaf of wheat seedling stressed by excess manganese using attenuated total reflectance Fourier transform infrared spectroscopy (FTIR) technique. The infrared spectra of the leaves of control and manganese-treated wheat plants have been recorded in the spectral region 485–4000 cm−1 at a resolution of 4 cm−1. The recorded spectrum has been analyzed with the help of curve-fitting method for the quantitative estimation of chemical contents and conformational changes. The study indicated changes arising in the polysaccharide, lignin, amino acid, secondary structure of protein, and lipid in the leaves of control and manganese-treated wheat plants. Manganese treatment increased the amount of cellulose, lignin, and amide II till 200 μM concentration, while a decrease was observed at 1000 µM concentration. Manganese induced conformational changes in the secondary structure of protein which was indicated by shifting of the bands to the higher wavenumber and change in the β sheet/α helix ratio. In addition, manganese stress decreased lipid content in the leaves of the wheat seedlings. The study demonstrates the potential of attenuated total reflectance FTIR for the non-invasive and rapid monitoring of the plants stressed with heavy metals.
In vitro and in vivo expression of human coagulation factor IX mediated by nonviral transfection of three plasmid vectors coding a factor IX gene

Gene therapy for hemophilia B is an attractive treatment because the current method of repeated infusion of purified factor IX concentrates has a high risk of viral infection and also is very expensive and inconvenient. The goal of the hemophilia B gene therapy is to introduce a continuous supply of factor IX at a therapeutic level. In this thesis, the efficiencies of three plasmid vectors containing human factor IX gene (pAAVCMV-hFIX, pFLAG-hFIX, and pCIneo-hFIX) transferred with three different cationic liposomes (DOTAP 1,2-dioleoyloxyproryl3-N,N,N-trimethylammonium chloride, DMDK dimyristyl aspartyl lysine, and DMEK dimyristoyl-glutamyl-lysine) were compared to each other. Under the optimized in vitro transfection conditions for 293 cells, transfection of pAAVCMV-hFIX with DMDK liposomes vector was able to produce approximately 181 ng factor IX/10 cells (3.6% of normal factor IX level) at 5 days post transfection. At the same conditions, pFLAG-hFIX and pCIneo-hFIX were expressed 132 ng factor IX/10

In vivo analgesic activity and safety assessment of Vitis vinifera L and Punica granatum L fruits extracts

Purpose: To investigate the analgesic properties of fruit extracts of Vitis vinifera (grape) and Punica granatum (pomegranate) in Albino mal mice. Methods: The analgesic activity of fruit extracts of V. vinifera and P. granatum were examined in vivo using thermal stimulus assays (i.e., tail immersion and hot plate) and acetic acid-induced writhing test using acetylsalicylic acid (0.1 g/kg, per os) as standard. The extracts were administered orally in doses of 1.0, 2.0 and 3.0 g/kg. Results: In acetic acid writhes test, both fruit extract pretreatments (1.0, 2.0 and 3.0 g/kg, per os) significantly decreased the number of writhes ( p < 0.0001) in a dose-dependent manner compared to control. The Index of Pain Inhibition (IPI) values following V. vinifera extract treatments were 36.52 % (1.0 g/kg), 66.67 % (2.0 g/kg) and 89.71 % (3.0 g/kg) which were significantly different from those for P. granatum extracts (45.39 %, 1.0 g/kg), 70.93 %, 2.0 g/kg) and 86.88 %, 3.0 g/kg) at equivalent doses of 2.0 and 3.0 g/kg of the extracts The fruit extracts of both species increased the reaction latency time. In tail-immersion assay, only the fruit extract of P. granatum significantly increased the response to heat stimulus at doses of 2.0 g/kg ( p < 0.05). Conclusion: The hydroalcohol fruit extracts of P. granatum and V. vinifera have potential analgesic effects. Further studies are needed to determine the active component responsible for this effect.

Health-related quality of life for patients with chronic conditions – the importance of group organised physiotherapy – a mixed methods study

Abstract Purpose The study investigated health-related quality of life (HRQoL) for patients with chronic conditions attending physiotherapy regularly and also examine the impact of physiotherapy on HRQoL. Methods In this mixed methods study, 52 patients attending group physiotherapy because of various chronic conditions answered the EuroQoL five-dimensional instrument (EQ-5D-3L) questionnaire (respondents). Three focus group interviews were conducted with nine of them (participants) and analysed according to Giorgi’s phenomenological method. Results Most of the respondents reported moderate problems with mobility, usual activities, and pain/discomfort on the EQ-5D dimensions. The interviews stated that physiotherapy was important for the participants because the physiotherapist used the patient-centred approach and managed to provide individually tailored patient education and pain management. The training had an impact on health-related quality of life and made it possible for the participants to take part in social life with family and friends. Recognition of limitations from peers in the group and from the physiotherapist played an important role for their motivation and adherence to the group training. Conclusion Health-related quality of life was affected for patients with chronic conditions. Group-based physiotherapy with individually tailored patient education made it possible to maintain a certain level of independence in everyday activities.
Foundational algebraic reasoning in the schemes of middle school students with learning disabilities

During the course of a three-month teaching experiment, two middle school students with learning disabilities were found to form operations foundational to algebraic reasoning as they constructed mathematical equivalence schemes. In particular, the students’ schemes were considered to be algebraic because they contained the cognitive roots of the distributive property, quantitative unit conservation, and solving linear equations of the form ax=bc with whole number solutions (where a, b, and c are whole number constants). The algebraic character of the students’ operating was based on the extent to which the students operated on the structure of their additive and/or multiplicative schemes as they solved tasks that required them to create equivalence between two multiplicative compilations.
Analysis of cheese

Publisher Summary This chapter presents that cheese is analyzed for a wide range of reasons, including to ascertain its composition as part of a quality control system or to generate data for nutritional labeling, to ensure compliance with standards of identity of a particular variety, assess the efficiency of production, and ensure the microbial safety of the product. Before analysis, cheese must be sampled properly, as the reliability of the results of any analytical procedure is dependent on how representative is the sample taken for analysis. The gross composition and pH of cheese provide some very important data related to quality and hence measurement of the pH and moisture, fat, and salt levels in cheese is common. Derived parameters, such as moisture-in-non-fat-substances, salt-in-moisture, and fat-in-dry-matter, are also calculated commonly. Cheese samples are often sent for microbiological analyses to ensure that the product is free from pathogenic organisms. In the context of scientific research in cheese, compositional data are also of great value as are counts for starter and non-starter organisms. Proteolysis, lipolysis, and the products of lactate and citrate metabolism can be followed by suitable laboratory techniques and volatile compounds determined, often by gas chromatography-mass spectrometry. A wide range of techniques has also been developed to measure the texture, functionality, and sensory properties of cheese.
Optical and electronic loss analysis of mesoporous solar cells

We review the art of complete optical and electronic characterization of the popular mesoporous solar cell motif. An overview is given of how the mesoporous paradigm is applied to solar cell technology, followed by a discussion on the variety of techniques available for thoroughly probing efficiency leaching mechanisms at every stage of the energy transfer pathway. Some attention is dedicated to the rising importance of computational results to augment loss analysis due to the complexity of solar cell devices, which have emergent properties that are important to account for, but difficult to measure, such as parasitic absorption.
High-Resolution Mapping of Tile Drainage in Agricultural Fields Using Unmanned Aerial System (UAS)-Based Radiometric Thermal and Optical Sensors

With the growing concerns of water quality related to tile drainage in agricultural lands, developing an efficient and cost-effective method of mapping tile drainage is essential. This research aimed to establish mapping of tile drainage systems in agricultural fields using optical and radiometric thermal sensors mounted on Unmanned Aerial System (UAS). The overarching hypothesis is that in a tile-drained land, spatial distribution of soil water content is affected by tile lines, therefore, contrasting soil temperature signals exist between areas along the tile lines and between the tile lines. Designated flights were conducted to assess the effectiveness of the UAS under various conditions such as rainfall, crop cover, crop maturity and time of the day. Image correction, mosaicking, image enhancements and map production were conducted using Agisoft and ENVI image analysis software. The results showed intermediate growth stage of soybean plants and rainfall helped delineating tile lines. In-situ soil temperature measurements revealed appropriate time of the day (14:00 to 18:00 h) for thermal image detection of the tile lines. The role of soil moisture and plant cover is not resolved, thus, further refinement of the approach considering these factors is necessary to develop efficient mapping techniques of tile drainage using UAS thermal and optical sensors.

Prediction of depressed Arab women using their tweets

ABSTRACT Social media is increasingly used to share thoughts and feelings. By mining the social media posts, a picture of users’ behavior may be obtained, to predict mental illnesses, like depression. Depression is seen as a taboo in the Arab world and cannot be discussed publicly out of fear of criticism. This led many to express their feelings over social media as an escape. Research has been conducted on the ability to use machine learning to make an early-stage diagnosis of depression. However, there is not enough research on this in the Arab world. This research was conducted on Arab women’s tweets during the COVID-19 pandemic to predict whether they have depression symptoms using machine learning. The proposed contribution is to create a Recurrent Neural Network (RNN) model to predict depression from tweets. The model is evaluated using 10000 tweets extracted from 200 users and the obtained results shows its effectiveness.
Developing global citizenship through geography education in Oman: exploring the perceptions of in-service teachers

Abstract Based on international trends, Omani education policy increasingly charges schools with fostering active citizens who have good attributes to achieve a good future. In this article, I considered the relationship between global citizenship and geography education in Oman. In particular, the study focused on how those teachers perceive global citizenship and how it is included in Omani geography textbooks. The study employed a qualitative methodology and data obtained by conducting semi-structured interviews with eight participants. The outcomes of the study showed that geography teachers defined global citizenship as a cosmopolitan perspective that focuses on common humanity. The participants believed that educating to develop global citizens is a necessary task for the Omani geography curriculum. Yet, this curriculum is currently focusing on the cognitive dimension rather than on the behavioural dimension of global citizenship.
Improved File-injection Attacks on Searchable Encryption Using Finite Set Theory

Searchable encryption (SE) allows the cloud server to search over the encrypted data and leak information as little as possible. Most existing efficient SE schemes assume that the leakage of search pattern and access pattern is acceptable. A series of work was proposed, instructing malicious users to use this leakage to come up with attacks. Especially, with a devastating attack proposed by Zhang et al., the cloud server can reveal the keywords queried by normal users by using some injected files. From the method of constructing uniform $(k,n)$-set of a finite set $A$ proposed by Cao, we put forward a new file-injection attack. In our attack, the server needs fewer injected files than the previous attack when the size of $T$ is larger than 9 and the size of keyword set is larger than $2T$, where $T$ is the threshold of the number of keywords in each injected file. Our attack is more practical and easier to implement in the real scenario.
