X-Ray Reflectivity Analysis Incorporated with Genetic Algorithm to Analyze the Y- to X Type Transition in CdA LB Film

The structure and layer distribution of cadmium arachidate Langmuir-Blodgett film were analyzed by the small angle X-ray reflectivity measurements using synchrotron radiation. Y-to X type transition was ocurred during the 39th passage of deposition of cadmium arachidate. Based on the measurement of the consumed area of the monolayer, it was determined that about 27.5 layer was deposited. Using the synchrotron X-ray, the reflectivity profile of cadmium arachidate LB film over the wide range of grazing angle was obtained. The X-ray reflectivity profile was analyzed using the recursion formula. By fitting the location and dispersion of the subsidiary maxima between the Bragg peaks of the measured reflectivity profile with that of the calculated reflectivity profile, the average thickness and the distribution of layer thickness were evaluated. The genetic algorithm was adopted to the fitting of reflectivity profile to evaluate the optimum value of the number distribution of layer. Based on the morphology measurement with an atomic force microscopy (AFM), the domain structure and mean roughness of LB films were obtained. The mean roughness value calculated based on the number of layer distribution obtained from the measurement by AFM is consistent with that obtained from X-ray reflectivity analysis.
Selective Oxidative Cleavage of Oleic Acid on Alumina Supported Metal Catalyst

Short-chain fatty acids (SCFAs) and medium-chain fatty acid (MCFAs) are valuable raw materials in wide range of chemical and medical applications. They can be converted to other derivatives by known chemical reactions. Unfortunately, both SCFAs MCFAs are not as abundant in nature as long-chain fatty acid (LCFAs). In this work, the oxidative cleavage of oleic acid, which is one of the most abundant unsaturated LCFAs in nature, was studied. The oxidation was induced by hydrogen peroxide catalyzed by a commercial alumina-supported metal catalyst. The products were analyzed by gas chromatography equipped with mass spectroscopy (GC/MS). The results revealed that MCFAs and SCFAs were detected in a product. In addition, aldehydes were also found. In this work, effects of catalyst loading, oleic acid-to-hydrogen peroxide ratio, reaction time were investigated and reported.
A clinical study of musculoskeletal dysfunction in targets of workplace bullying

Abstract Background Workers exposed to bullying often report musculoskeletal symptoms. In this study we have clinically evaluated the prevalence and nature of musculoskeletal dysfunction among a group of workers exposed to bullying and studied the relationship between clinical findings and self-reported musculoskeletal and mental symptoms. Materials and methods In a cross-sectional study, 144 patients admitted to an outpatient clinic for victims of workplace bullying were assessed with the Global Physiotherapy Examination 52 (GPE-52), a standardised test battery examining posture, respiration, movement, muscle and skin. The patients filled in self-report questionnaires regarding musculoskeletal symptoms (MSI), anxiety and depression (The Hospital Anxiety and Depression Scale, HADS) and post-traumatic stress symptoms (Impact of Events Scale revised version, IES-R). Results Patients victimised by bullying showed reduced flexibility, reduced ability to relax, restricted respiration and tense and painful muscles. The total GPE-52 sum-score and the main domains Movement and Muscle had significant correlations with most self-reported health variables, strongest between the subdomain Flexibility and HADS-D (r = 0.37) and HADS-A (r = 0.36). Conclusions Victims of bullying have clinically evident musculoskeletal dysfunctions that were further found to have a relationship with self-reported mental symptoms. Future health services for these patients should be multi-dimensional and include a bodily assessment by a physiotherapist and relevant treatment when needed.
Diversity of Segetal Flora in Salix viminalis L. Crops Established on Former Arable and Fallow Lands in Central Poland

The flora of willow (Salix viminalis L.) plantations consists of various plant groups, including plants related to arable land, called segetal plants. Knowledge of this flora is important for maintaining biodiversity in agroecosystems. The aim of the study was to assess the segetal flora of the willow plantations in central Poland, depending on the land use before the establishment of the plantations (arable land or fallow) and the age of the plantations. Moreover, the aim was also to check for the presence of invasive, medicinal, poisonous and melliferous species. The vegetation accompanying willow was identified based on an analysis of 60 phytosociological relevés performed using the Braun-Blanquet method. For each species, the following parameters were determined: the phytosociological class; family; geographical and historical group; apophyte origin; biological stability; life-form; and status as an invasive, medicinal (herbs), poisonous or melliferous species. The results were statistically processed. Segetal species accounted for 38% of the flora accompanying willow. The plantations on former arable land were richer in segetal species than those on fallow. Mostly, short-lived and native species dominated. In line with the age of the plantations, the number of segetal species decreased. The share of apophytes increased, and anthropophytes decreased. Furthermore, many valuable plants were found among the flora accompanying willow.

In vitro biocontrol scenarios of Bacillus amyloliquefaciens subsp. amyloliquefaciens strain RLS19 in response to Alternaria macrospora, an Alternaria leaf spot phytopathogen of Bt cotton

Alternaria macrospora (Zimm.) is most critical phytopathogen causing Alternaria leaf spot disease of transgenic cotton having regional, national, and international significance. In the present research work, Bacillus amyloliquefaciens subsp. amyloliquefaciens strain RLS19 previously isolated from rhizospheric niches of healthy of Bt cotton plant was screened against A. macrospora by dual culture technique. Bacillus sp. significantly killed the radial mycelial growth of A. macrospora, that is, 98.08%. On finding the mechanism, it was revealed that B. amyloliquefaciens subsp. amyloliquefaciens strain RLS19 produced diffusible non-volatile secondary metabolites, siderophore, and chitinase enzyme which make contributions to inhibit the mycelial growth of A. macrospora during dual culture screening. In addition, the gas chromatography–mass spectrometry evaluation of crude extract discovered the presence of three bioactive compounds specifically acetamide, N-methyl-N-[4-(3-hydroxypyrrolidinyl)-2-butynyl]-; pyrrolo[1,2-a] pyrazine-1,4-dione, hexahydro-, and 2,5-Piperazinedione, 3,6-bis(2-methylpropyl)with the outstanding antimicrobial antibacterial and antifungal activity which contributed in the inhibition of A. macrospora.
Practical Prediction of the Boil-Off Rate of Independent-Type Storage Tanks

Because environmentally-friendly fuels such as natural gas and hydrogen are primarily stored in the form of cryogenic liquids to enable efficient transportation, the demand for cryogenic fuel (LNG, LH) ships has been increasing as the primary carriers of environmentally-friendly fuels. In such ships, insulation systems must be used to prevent heat inflow to the tank to suppress the generation of boil-off gas (BOG). The presence of BOG can lead to an increased internal pressure, and thus, its control and prediction are key aspects in the design of fuel tanks. In this regard, although the thermal analysis of the phase change through a finite element analysis requires less computational time than that implemented through computational fluid dynamics, the former is relatively more error-prone. Therefore, in this study, a cryogenic fuel tank to be incorporated in ships was established, and the boil-off rate (BOR), measured considering liquid nitrogen, was compared with that obtained using the finite element method. Insulation material with a cubic structure was applied to the cylindrical tank to increase the insulation performance and space efficiency. To predict the BOR through finite element analysis, the effective thermal conductivity was calculated through an empirical correlation and applied to the designed fuel tank. The calculation was predicted to within 1% of the minimum error, and the internal fluid behavior was evaluated by analyzing the vertical temperature profile according to the filling ratio.
Research on the development and application of museum cultural Resources display based on virtual reality technology

The development of museum cultural industry, as the key content of the development of national cultural industry, affects the inheritance of national culture and history. Due to the constant update of hightech, new media and other technologies, the display of cultural resources in museums is becoming more and more diversified. The application of virtual reality technology, digital interaction technology, new media and other technologies brings new vitality to the display design of modern museums. Under the background of this era, the exhibition of museum cultural resources is researched and explored. At present, virtual reality technology is gradually applied in the display and dissemination of cultural resources. This paper discusses how to realize the application of this technology in the display of cultural resources in museums.
The Mechanics of Creep, Slow Slip Events, and Earthquakes in Mixed Brittle‐Ductile Fault Zones

Geological observations show that fault zone composition varies and often accommodates a mixture of brittle and ductile deformation. There is growing evidence that the nature of this mixture may play an important role in determining whether the fault creeps steadily or slides in slow slip events (SSEs) and/or fast earthquakes. Using numerical experiments of slip events in a fault zone of finite thickness, we explore how the ratio of brittle to ductile material and the absolute friction change resulting from a variation in slip velocity, |b−a|, affect energy partitioning and slip behavior in brittle‐ductile mixtures. We treat brittle material as Mohr‐Coulomb elastoplastic and ductile material as Maxwell viscoelastic. We simulate velocity‐weakening ( a−b<0 ) behavior in the brittle part of the mixture and velocity‐strengthening ( a−b≥0 ) behavior in the ductile part using a rate‐and‐state formulation dependent on plastic strain accumulation. We show that: (1) mixtures can exhibit multiple slip behaviors including earthquakes and slow slip, (2) highly brittle mixtures do not tend to generate SSEs while weakly brittle mixtures can generate slow slip over a wider range of compositions, (3) structural features formed during simulated creep, SSEs, and earthquakes share notable similarities with structures observed in natural fault zones. We find that slip‐synchronous strengthening in the ductile portion of the mixture controls whether a rupture propagates as SSEs of yearlong durations. Shorter duration SSEs occur when the length of the plastic shear segments formed during slip is similar to the characteristic weakening distance for an earthquake.
Outside‐in Politicization of EU–Western Africa Relations: What Role for Civil Society Organizations?

This article explores the empirical relevance of researching outside-in politicization processes in European studies. To this end, it examines to what extent and how civil society organizations (CSOs) have contributed to the politicization of EU policies towards Western Africa in two cases: the negotiation of Economic Partnership Agreements and the EU ’ s engagement with the G5 Sahel. CSOs were strongly engaged in the trade negotiations, while they were largely excluded from the G5 Sahel process. In both cases this was due to CSOs ’ own initiatives, or the absence thereof, with these strongly linked to being either invited or discouraged by of ﬁ cial actors. The article argues that authority transfer and the domestic context – including state fragility and state – society relations – are relevant to explaining the (non-)involvement of CSOs in outside-in politicization.
Comparison of regular and irregular 32 pulse density modulation patterns for induction heating

In this study, an induction heating (IH) application is carried out by transferring the maximum power extracted from photovoltaic (PV) panels to the stainless steel with the designed regular and irregular 32 pulse density modulation (PDM) controlled series resonant inverter. The main objective of this study is to analyse the changes in the system due to regular and irregular PDM patterns. Maximum power point tracker (MPPT) is used to control the output power at different solar irradiation values with varying PDM patterns. Regular and irregular PDM control methods are compared in terms of MPPT efﬁciency, cost, algorithm complexity, logic control structure and current/voltage stresses of the power switches. Zero current switching (ZCS) conditions are provided by using phase locked loop (PLL) technique at all power points of the PV system. The appropriate switching conditions are tracked continuously at resonant frequency, and therefore soft switching is realised. Perturb and observe (P&O) algorithm is used with the aim of tracking the maximum power in PV panels and high tracking efﬁciency is obtained with PDM-controlled P&O MPPT algorithm. ATMEL328P-AU microcontroller is used to control the inverter in the system.
Color, physicochemical parameters and antioxidant potential of whole grape juices subject to different UV-C radiation doses

Knowing that moderate stress such as UV radiation can activate defense mechanisms in plants, the use of UV-C radiation appears as hypothesis of a promising technique that would help to stimulate and enhance beneficial compounds for health, through a clean and healthy technology. In this study, the possible induction of secondary metabolism, the increase in the content of phytochemical compounds and physicochemical changes through the use of UV-C radiation were evaluated on whole grape juices produced with Vitis labrusca grapes, cultivar Isabel Precoce. Grapes were harvested, sanitized, exposed to UV-C radiation at doses of 0, 2, 4 and 6 KJ m-2, and then the juices were prepared and packed into amber glass bottles at room temperature. Analyses were performed at 0, 30, 60, 90 and 120 days of storage. Based on results obtained and conditions in which the experiment was performed, UV-C treatment in grapes caused abiotic stress in the fruits, affecting color, titratable acidity, soluble solids/titratable acidity ratio, vitamin C and percentage of protection against oxidation. Application of UV-C did not change levels of phenolic compounds in fruit juices or the percentage of scavenging free radicals, pH and soluble solids.
Roles of Anthropogenic Forcing and Natural Variability in the Record- Breaking Low Sunshine Event in January–February 2019 over the Middle-Lower Yangtze Plain

In January–February 2019, the Middle-Lower Yangtze Plain, accounting for ~1/8 of China’s territorial areas, endured the shortest sunshine duration (SD) since 1961 (Figs. 1a–b and Fig. ES1a). The regional average of daily SD (1.6 h) was approximately 57% shorter than the 1961– 90 climatology (3.7 h). Due to the continuous rainy and low sunshine in early 2019, the acreage and yield per unit of early rice were reported to decrease by 341.3 thousand hectares and 64.8 kg ha−1 compared with 2018, respectively (National Bureau of Statistics of China; www.stats.gov. cn/tjsj/sjjd/201908/t20190826_1693488.html).

Sintesis Imunogen Oksitetrasiklin-Tolidin-BSA dan Produksi Antibodi Anti- Oksitetrasiklin untuk Pengembangan Deteksi Residu Oksitetrasiklin Secara Enzym Linked Immunoassay

Widiastuti R, Murdiati TB, Riandari D. 2013. Synthesis of an oxytetracyline-tolidin-BSA immunogen and antibodies production of anti-oxytetracyline developed for oxytetracyline residue detection with enzyme-linked immunosorbent assays technique. JITV 18(2): 138-145. An oxytetracycline-tolidin-bovine serum albumin (OTC-tolidin-BSA)-conjugate was synthezed as immunogen for producing specific antibodies in immunized rabbits that would be used as reagent for development of OTC residue detection with enzymlinked immunoassays technique. The immunogen was prepared through diazotization tolidin and subsequently reacted with OTC. The red purple immunogen of OTC-tolidin-BSA absorbed at wave lengths of 277 nm and 488 nm under UV screening absorbances and confirmation with the high performance liquid chromatography (HPLC) showed the absence of peak at retention time of 3.46 minutes. Characaterized result with SDS-PAGE showed the molecular weight of the OTC-tolidin-BSA at 69.79 kDA. Subsequently, the immunogen was immunized into New Zealand rabbits in order to produce the polyclonal antibodies. The antibodies were purified using a protein A sepharose column. The OD optimum responses of 0.92 to 1.20 were obtained from the second fractionation at dilution of 1/1000 by titrating the antibodies and OTC-tolidin-BSA coating antigen at concentration of 10 Cg/mL on several bleeding times.
Enhanced oil-in-water droplet generation in a T-junction microchannel using water-based nanofluids with shear-thinning behavior: A numerical study

Nanofluids are widely used as the continuous phase during droplet formation in microsystems due to their impressive features such as excellent thermal, magnetic, and interfacial properties. Although it is well-known that nanofluids are susceptible to exhibit non-Newtonian behavior even at a low concentration of nanoparticles, effects of non-Newtonian behavior of nanofluids have not been studied on droplet formation thus far. In this study, oil-in-water droplet formation with a relatively high viscosity ratio of the immiscible phases was studied numerically in a T-junction microchannel. To inspect the non-Newtonian effects of aqueous nanofluids on droplet formation, empirical data on the rheological behavior of various types of nanofluids were explored. Finally, two water-based nanofluids with shear-thinning behavior were chosen as the continuous phase for numerical simulations. The numerical procedure was validated against some experimental models. Afterward, droplet length was determined for different capillary numbers, flow rate ratios, and nanoparticle concentrations, and some scaling laws were proposed to predict droplet length in different droplet formation regimes. The results showed that using nanofluids with shear-thinning behavior as the continuous phase results in a decrease in droplet size, and this reduction is more intensified as the concentration of nanoparticles increases. Furthermore, it was observed that the change in the droplet formation regime through manipulating the flow rates does not occur easily when pure water is used as the continuous fluid due to the high viscosity ratio of the immiscible phases. However, when nanofluids are employed as the continuous fluid, the droplet formation regime can be changed more easily due to the enhancement of viscous shear force in the continuous phase. Hence, in addition to the well-known advantages of nanofluids in droplet formation processes, nanofluids can be raised as a new alternative for the continuous phases to administer the droplet size and formation regimes rather than using chemical additives for tuning the rheological properties.
Hyperbolic-SVD-Based Square-Root Unscented Kalman Filters in Continuous-Discrete Target Tracking Scenarios

This article aims at presenting novel square-root unscented Kalman filters (UKFs) for treating various continuous-discrete nonlinear stochastic systems, including target tracking scenarios. These new methods are grounded in the commonly used singular value decomposition (SVD), that is, they propagate not the covariance matrix itself but its SVD factors instead. The SVD based on orthogonal transforms is applicable to any UKF with only nonnegative weights, whereas the remaining ones, which can enjoy negative weights as well, are treated by means of the hyperbolic SVD based on <inline-formula><tex-math notation="LaTeX">$J$</tex-math></inline-formula>-orthogonal transforms. The filters constructed are presented in a concise algorithmic form, which is convenient for practical utilization. Their two particular versions grounded in the classical and cubature UKF parameterizations and derived with use of the It<inline-formula><tex-math notation="LaTeX">$\hat{\rm o}$</tex-math></inline-formula>-Taylor discretization are examined in severe conditions of tackling a seven-dimensional radar tracking problem, where an aircraft executes a coordinated turn, in the presence of ill-conditioned measurements.
