AbstractThe use of chemical insecticides, especially as ultra low volume (ULV) formulations, against locusts and grasshoppers will continue for the foreseeable future; therefore application techniques for microbial agents should be as compatible as possible with existing practice. Low volume and ULV spraying of deuteromycete conidia in oil-based formulations have produced very promising acridid control results in the field, although baiting, dusting, and hydraulic application techniques have also been tested for a wide range of pathogens.The key problems for further research and development appear to be the logistics and supply of consistently reliable formulations for application on a large scale, and the determination of mechanisms for effective dose transfer in the field. The application of suspended particulate matter can present special problems with rotary and other atomizers.

Abstract Dusts, emulsions, concentrates, and technical material covering a wide range (1%92%) of naled were diluted or extracted with chloroform. Dibutyl phthalate was added to sample extracts as an internal standard before gas-liquid chromatographic (GLC) injection. Twelve column packings covering the entire polarity scale were tested, and 3% XE-60 was chosen, based on the best resolution for a difficult-to-separate low volume concentrate. Response is linear from 1 to 50 mg naled/ml and the coefficient of variation for the GLC step is 0.81%. Of 29 other active ingredients which have been formulated with naled, diazinon and 1 isomer of BHC elute with naled, while dicrotophos elutes with the internal standard.

In order to establish a large sample of the standardization of the norm of the National College Students’ physical exercise behaviour, this study uses the change scale of college students physical exercise behaviour, and a large range of survey of the university students physical exercise behaviour. According to the statistical analysis of the data obtained by the national college students physical exercise behaviour’ change standard norm, it can provide a reliable, effective and valuable reference for the study of college students physical exercise behaviour. In the cross theoretical model, the lack of the determination of the stage of the change, especially after a wide range of survey, produces the precise analysis and interpretation. After a large scale of the investigation, this study not only has a simple region to change the stage and change process, but also to find the corresponding relationship between them, as well as the different stages of the weight of the change process.

Abstract A liquid chromatographic method for determination of deltamethrin In 6 different technical and formulated products was collaboratively studied In 14 laboratories. Each sample Is dissolved In lsooctane-1,4-dloxane (80 + 20), separated by LC on a silica gel column (cyano column for ultra low volume formulation), and detected at 254 nm (230 nm for ≤0.5% powder formulations). Quantitation Is done by peak area measurements. Relative standard deviations for repeatability and reproducibility ranged from 0.56 to 1.00% and from 0.76 to 2.90%, respectively. The method has been approved Interim official first action by AOAC as a CIPAC-AOAC method.

Analytical Relations

The rapidly increasing number of stellar spectra obtained by existing and future large-scale spectroscopic surveys feeds a demand for fast and efficient tools for the spectroscopic determination of fundamental stellar parameters. Such tools should not only comprise customized solutions for one particular survey or instrument, but, in order to enable cross-survey comparability, they should also be capable of dealing with spectra from a variety of spectrographs, resolutions, and wavelength coverages. To meet these ambitious specifications, we developed ATHOS (A Tool for HOmogenizing Stellar parameters), a fundamentally new analysis tool that adopts easy-to-use, computationally inexpensive analytical relations tying flux ratios (FRs) of designated wavelength regions in optical spectra to the stellar parameters effective temperature (T eff), iron abundance ([Fe/H]), and surface gravity (log g). Our T eff estimator is based on FRs from nine pairs of wavelength ranges around the Balmer lines Hβ and Hα, while for [Fe/H] and log g we provide 31 and 11 FRs, respectively, which are spread between ∼4800 Å and ∼6500 Å; a region covered by most optical surveys. The analytical relations employing these FRs were trained on N = 124 real spectra of a stellar benchmark sample that covers a large parameter space of T eff ≈ 4000–6500 K (spectral types F to K), [Fe/H] ≈ −4.5 to 0.3 dex, and log g ≈ 1–5 dex, which at the same time reflects ATHOS’ range of applicability. We find accuracies of 97 K for T eff, 0.16 dex for [Fe/H], and 0.26 dex for log g, which are merely bounded by finite uncertainties in the training sample parameters. ATHOS’ internal precisions can be better by up to 70%. We tested ATHOS on six independent large surveys spanning a wide range of resolutions (R = λ/Δ λ ≈ 2000–52 000), amongst which are the Gaia-ESO and the SDSS/SEGUE surveys. The exceptionally low execution time (< 30 ms per spectrum per CPU core) together with a comparison to the literature parameters showed that ATHOS can successfully achieve its main objectives, in other words fast stellar parametrization with cross-survey validity, high accuracy, and high precision. These are key to homogenize the output from future surveys, such as 4MOST or WEAVE.

AbstractPrecise measurements of heliographic position of solar filaments were used for determination of the proper motion of solar filaments on the time-scale of days. The filaments have a tendency to make a shaking or waving of the external structure and to make a general movement of whole filament body, coinciding with the transport of the magnetic flux in the photosphere. The velocity scatter of individual measured points is about one order higher than the accuracy of measurements.

Titanium nitride (TiN) films have historically been used as diffusion barrier between silicon and aluminum, as an adhesion layer for tungsten deposition and as an interconnect material etc. Recently, the role of TiN films as contact barriers in very large scale silicon integrated circuits (VLSI) has been extensively studied. TiN films have resistivities on the order of 20μ Ω-cm which is much lower than that of titanium (nearly 66μ Ω-cm). Deposited TiN films show resistivities which vary from 20 to 100μ Ω-cm depending upon the type of deposition and process conditions. TiNx is known to have a NaCl type crystal structure for a wide range of compositions. Change in color from metallic luster to gold reflects the stabilization of the TiNx (FCC) phase over the close packed Ti(N) hexagonal phase. It was found that TiN (1:1) ideal composition with the FCC (NaCl-type) structure gives the best electrical property.

This study is motivated the identification of policies issued by the regional Governmentof Rokan Hulu in the form of Regulatory region number 1 by 2015 on the determination of thevillage and Indigenous Village. Political dynamics based on various interests against themanufacture of, and decision-making in the process of formation of the corresponding localregulations determination of Indigenous Villages in the Rokan Hulu is impacted to a verysignificantamount of changes from the initial draft of the number i.e. 21 (twenty one) the villagebecame Customary 89 (eighty-nine) the Indigenous Villages who have passed. Type of thisresearch is a qualitative descriptive data analysis techniques. The research aims to describe theState of the real situation in a systematic and accurate fact analysis unit or related research, aswell as observations of the field based on the data (information). Method of data collectionwas done with interviews, documentation, and observations through fieldwork (field research).The results of the research on the process of discussion of the draft local regulations andmutual agreement about Designation of Indigenous Villages in the Rokan Hulu is, showed thatthe political dynamics that occur due to the presence of various political interests, rejectionorally by Villagers who were judged to have met the requirements of Draft Regulations to beformulated and the area for the set to be Indigenous Villages, and also there is a desire fromsome villages in the yet to Draft local regulations in order to set the Indigenous village , there isa wide range of interests of these aspects influenced the agreement to assign the entire localVillage which is in the Rokan Hulu become Indigenous village, and the village of Transmigrationinto administrative Villages where the initiator of the changes in the number of IndigenousVillages in the Rokan Hulu it is the desire of the local Government of its own.
