Sar? 85 (Linum usitatissimum L.) linseed variety was used in this study. Linseed was cultivated at 2008 (LS-08) and 2009 (LS-09) without fertilizer. In addition, at 2009 diammonium phosphate [(NH4)2HPO4] and ammonium nitrate (NH4NO3) were applied (LSF-09). The linseeds were analyzed for protein, ash and oil contents and fatty acid compositions. There were differences among harvesting years for oil, protein and ash contents of the seeds. The greater oil and protein contents were obtained during LS-08 compared with LS-09. There were no significant difference in protein and ash content between LS-09 and LSF-09 while a significant difference was observed in oil content. Seed protein, oil and ash contents were significantly affected by the harvesting year, but only oil content was affected by the fertilizer treatment. There are significant differences in palmitic, stearic, oleic, ??-linolenic and arachidic acid between LS-08 and LS-09. While palmitic, stearic, oleic acid decreased, ??-linolenic and arachidic acid increased during 2009 harvesting year. LSF-09 has the highest amount of ??-linolenic acid. The fertilizing treatment seems to have an increasing effect on the amount of ??-linolenic acid, while it has a decreasing effect on the oleic acid content. 相似文献

The purpose of this study was to evaluate the knowledge, attitudes and practices among food service staff with regards to food hygiene in hospitals in Edirne, Turkey, and to provide baseline data for implementing HACCP in hospital food services by carrying out a questionnaire by a face-to-face interview. The current study shows that food service staff in Edirne hospitals have insufficient knowledge regarding the basics of food hygiene. And also revealed a discrepancy between attitudes and practices towards food hygiene. There is an immediate need for continuous training among food handlers regarding safe food handling practices. 相似文献

Radio-over- fibre (RoF) technology is receiving large attention due to its ability to provide simple antenna front ends, increased capacity and increased wireless access coverage. Coherently detected RoF systems would enable the information to be carried in both the amplitude and phase or in different states of the polarisation of the optical field. Additionally, the selectivity of coherent receiver is very well suited for access networks. We present a 90° optical hybrid built on a silicon-on-insulator planar light-wave circuit, which can be used as the optical front end of the digital coherent receiver in a digitised RoF link and will lead to reduced receiver footprint and cost. The optical hybrid circuit includes 2?×?2 and 4?×?4 multimode interference (MMI) splitters, in a polarisation diversity configuration. The simulation results at vacuum wavelength 1,550 nm show polarisation independence and phase errors between the ports of less than 0.03°. The properties of the prototyped 4?×?4 MMI were measured over a wide range of wavelengths. The 2?×?2 and 4?×?4 MMI showed nearly equal splitting ratios. Measurements of the relative phase relationship between the ports for Transverse Electric mode polarisation are shown to match the simulation results. 相似文献

Sulphanilamide was determined to be a new inhibitor of lactoperoxidase (LPO) with an IC50 of 0.848.10−5 M. The Ki for sulphanilamide was determined to be 3.57.10−5 M and sulphanilamide showed competitive inhibition, which makes it a suitable ligand for constructing a Sepharose 4B-l-tyrosine affinity matrix. The affinity matrix was synthesised by coupling sulphanilamide as the ligand and l-tyrosine as the spacer arm to a cyanogen bromide (CNBr)-activated-Sepharose 4B matrix. Lactoperoxidase was purified 409-fold from the synthesized affinity matrix in a single step, with a yield of 62.3% and a specific activity of 40.9 EU/mg protein. The enzyme activity was measured using ABTS as a chromogenic substrate (pH 6.0). The degree of LPO purification was monitored by SDS–PAGE and its Rz (A412/A280) value. The Rz value for the purified LPO was found to be 0.7. Maximum binding was achieved and Km and Vmax values were determined. 相似文献

Inert gas shrouding practices were simulated using a full-scale, four-strand water model of a 12-tone, delta-shaped tundish.
Compressed air was aspirated into the ladle shroud to model volumetric flow rates that range between 2 and 10 pct of steel
entry flows. Bubble trajectories, slag layer movements, and flow fields, were visualized. Flow fields were visualized using
particle image velocimetry (PIV). A numerical model also was developed using discrete phase modeling (DPM) along with the
standard k-ε turbulence model with two-way turbulence coupling. Predicted flow fields and bubble trajectories corresponded with the
water model experiments. 相似文献

Modulus of elasticity is an important parameter used for the structural assessment and retrofitting of concrete structures. In this study, an experimental investigation on the modulus of elasticity of concrete was carried out, the results of which is presented. 60 mixtures were prepared, in which the effects of water/cement ratio, maximum size of the aggregate, aggregate type, and fly ash content were investigated. In order to obtain very low quality concrete, the water/cement ratios were increased to as high as 2.2. Modulus of elasticity of the concretes was obtained according to ASTM C469. Compressive strength and ultrasound pulse velocities of the concretes were also recorded. The experimentally obtained modulus of elasticity values were compared with those calculated by using prediction models given in a selection of codes of practice. Dynamic moduli of elasticity of the concretes were also obtained. 相似文献

The objective of testing is to determine whether an implementation under test conforms to its specification. In distributed
test architectures involving multiple remote testers, this objective can be complicated by the fact that testers may encounter
coordination problems relating to controllability (synchronization) and observability during the application of tests. Based
on a finite state machine (FSM) specification of the externally observable behaviour of a distributed system and a distinguishing
sequence, this paper proposes a method for constructing a checking sequence where there is no potential controllability or
observability problems, and where the use of external coordination message exchanges among testers is minimized. The proposed
method does not assume a reliable reset feature in the implementations of the given FSM to be tested by the resulting checking
sequence.

Although knowledge discovery from large relational databases has gained popularity and its significance is well recognized, the prohibitive nature of the cost associated with extracting such knowledge, as well as the lack of suitable declarative query language support act as limiting factors. Surprisingly, little or no relational technology has yet been significantly exploited in data mining even though data often reside in relational tables. Consequently, no relational optimization has yet been possible for data mining. We exploit the transitive nature of large item sets and the so called anti-monotonicity property of support thresholds of large item sets to develop a natural least fixpoint operator for set oriented data mining from relational databases. The operator proposed has several advantages including optimization opportunities, and traditional candidate set free large item set generation. We present an SQL3 expression for association rule mining and discuss its mapping to the least fixpoint operator developed in this paper. 相似文献

In this study, the elastic–plastic stress analysis of a curvilinearly orthotropic rotating annular disc is investigated analytically for strain-hardening material behavior. To be able to see the separation of the plastic region, a few angular velocities are taken into consideration for such an analysis. Radial and circumferential stress components are obtained to increase angular velocity. It is seen that the magnitudes of the circumferential stress components are higher than those of the radial stress components. The magnitudes of the residual stress component of the circumferential stress and plastic flow are the highest at the inner surface. The radial displacements in both the elastic and plastic solutions calculated analytically have higher values at the inner surface than those of the outer surface for all the angular velocities. 相似文献
