High levels of FFA have been a recurring problem in the seed oil of Ontario-grown, canola-quality summer rape (Brassica napus L.). Examination of seed samples from the Eastern Canadian Co-operative Cultivar Trials conducted at several locations in 1988–1993 showed significant, consistent differences in FFA levels among cultivars. In each year from 1988 to 1991 the cultivars Kristina, Delta and Westar had FFA levels that were about 40% of those of Global and the triazine-tolerant cultivars Stallion, OAC Triton and OAC Triumph. Pearson's correlations and Spearman's rank correlation between years for FFA levels of genotypes were all significant, with the exception of the Spearman's rank correlation between 1992 and 1993. Significant differences in FFA occurred among locations in southern Ontario, but location differences were not consistent across years. Cultivars grown in western Canada, however, had FFA levels between 2 and 41% of their FFA levels at the southern Ontario locations. The FFA levels of cultivars at one Ontario location were significantly correlated with the mean FFA levels of the same cultivars from all the other Ontario locations in the same year, 28 out of 34 times. Correlations were higher before the high-FFA cultivars were removed from the trials in 1991. Screening of lines in a breeding program for susceptibility to high FFA at one southern Ontario location appeared to be predictive of FFA levels at other southern Ontario locations. Selection of cultivars that have low FFA levels should reduce the FFA problem in Ontario-grown spring canola. Key words:Brassica napus, canola, free fatty acids, cultivars, stress, environment

<b><i>Background:</i></b> The acute kidney injury (AKI) risk score helps detect moderate and severe AKI in the next 12–24 h. However, inappropriate urine collection may impact its results. <b><i>Aim:</i></b> The aim of this study was to evaluate the stability of NephroCheck® after urine storage at different temperatures. <b><i>Methods:</i></b> The urine sample was centrifuged and split into 3 tubes. One was tested as soon as possible by the laboratory. The other 2 samples were frozen at −20 and −80°C, and the NephroCheck® test was performed 8 weeks later. <b><i>Results:</i></b> The mean values of the AKI risk score were 1.19 ± 0.93, 1.15 ± 1.14, and 1.20 ± 1.11 (ng/mL)<sup>2</sup>/1,000 for fresh urine, −20, and −80°C, respectively (<i>p</i> = 0.70). Spearman’s rank correlation for −20 and −80°C versus immediate processing was strong with a rho of 0.82 and 0.98, respectively. <b><i>Conclusion:</i></b> The AKI risk score was relatively stable. Urine could be collected without dry ice or liquid nitrogen and kept for up to 8 weeks with either −20 or −80°C freezing with stable NephroCheck® results.

Abstract. Background: The aim of this study was to investigate the influence of age on the ultrastructure of venous valve morphology in patients with C2 classified chronic venous disorders according to the CEAP classification. Patients and methods: The study population consisted of 16 consecutive patients with varicose veins (C2). The mean age was 49.8 years (30–66). The (pre-) terminal valve including the vessel wall was harvested within the proximal 2 centimetres of the great saphenous vein. The mean thickness (volume-to-surface ratio = V/S ratio) of elastin, collagen, endothelium and of the entire valve was determined. A blinded morphologist performed the examination by transmission electron microscopy and stereology. Analyses by Pearson’s product moment correlation, Kendall’s tau and Spearman’s rank correlation were performed to investigate whether there is a correlation between age and the ultrastructural morphology. Results: Stereological analysis of the valves demonstrated a mean V/S ratio (signifying a thickness estimation) for elastin of 0.87 μm3/μm2, for collagen of 18.0 μm3/μm2, for endothelium of 0.65 μm3/μm2, and for the entire valve of 25.2 μm³/μm². Statistical analyses showed no statistically significant correlation between age and the ultrastructural morphology in this patient group. Conclusions: The ultrastructural morphology of the venous valves in chronic venous disorders may not depend on age in patients presenting with C2 disease. This conclusion may or may not apply to all C classes as we investigated a homogenous group of patients with C2 limbs.

The characteristic of bulls-producers of red breeds of OAO Barnaulskoe breeding enterprise on the quality of sperm and its resistance to cryopreservation are presented. The breeding enterprise has examined samples of water, soil, feed for the content of heavy metals. In the studied samples, no excess of the LOC was found. The research results were processed on a PC using population statistics methods. Angler bulls produced the largest amount of ejaculates unsuitable for cryopreservation. It is 20.6%. According to this indicator, they surpassed the producers of red Danish and red steppe breeds by 4.1-7.8%. The animals of the latter breed showed the smallest amount (1.7%) of ejaculates rejected after defrost. In Angler bulls, this indicator was 5.95%, in red Danish bulls it was 2.95%, which is 3.52 and 1.75 times higher than in red steppe breeders (P <0.01-0.001). Significant differences were established between individual bulls of the red steppe breed in the number of ejaculates rejected before cryopreservation (2.84-22.29%) and after defrost (0-7.09%). The differences between breeds in the frequency of rejected ejaculates before freezing and after cryopreservation indicate a certain role of heredity in the resistance of animals for these indicators. Spearman’s rank correlation coefficient between these traits was 0.312. It indicates the possibility of preliminary assessment and selection of bulls according to the first indicator. But the final assessment of the bull-producers can be made by the frequency of rejected ejaculates after thawing. We propose to consider the issue of additional accounting in breeding programs for the resistance of the seed of bulls-producers to cryopreservation.

Aim. assessment  of  accessions from the lentil national collectionon the level of drought resistance on a PEG-6000 solution. Methods. The germination was carried out in growth plates on a filter paper bed at t = 21ºC for five days. A working solution of PEG-6000 with concentrations of 15.0% and 19.5% was used. The control was germinated in distilled water. The length of the shoot and root was measured and the level of depression of growth processes was calculated. Results. When germinating on a PEG-6000 solution with 19.5% concentration, the overwhelming number of accessions had depression indicators for shoots above 85% and above 60% for roots, and therefore it was not possible to isolate samples tolerant to the action of PEG-6000. When germinating on a 15%  solution of PEG-6000, a wider range of variation was noted: depression in feature of “root length” ranged from 0% to 100%, “shoot length” - from 50% to 100%. The calculated Spearman's rank correlation coefficient confirms that shoots, in comparison with roots, are more sensitive to the action of osmotic in both variants of the experiment. Conclusions. The concentration of PEG-6000 was established for the selection of sources and the ranking of samples by drought resistance. Sources of drought resistance were identified from the studied sample – accessions subsp. microsperma: 8-MIL M 5 (UD0600007, France), UD0600028 (Ethiopia), Giza 9 (UD0600065, Egypt) and the accession-standard of drought resistance is Gornostepnaya (UD0600131, Armenia) subsp. microsperma.

Material selection is a very entangled and decisive stage in the design and development of products. There are large numbers of on hand and newly developed materials available in the market. In addition, inability to select the correct materials adversely affects the reputation and profitability of the company. Thus, designers need to study and trace the performance of available materials with appropriate functionalities. Thus, this research aims at establishing an efficient and systematic platform for the optimum selection of materials while accommodating the designated conflicting performance requirements. The developed model encompasses designing a hybrid decision support system in an attempt to circumvent the shortcomings of single multi-criteria decision making-based (MCDM) models. First, the objective relative importance weights of attributes are interpreted capitalizing on Shannon entropy algorithm. Then, an integrated model that encompasses the utilization of six different types of multi-criteria decision making algorithms is designed to create a reliable selection of material alternatives. The utilized MCDM algorithms comprise weighted product method (WPM), simple additive weighting (SAW), additive ratio assessment (ARAS), new combinative distance-based assessment (CODAS), complex proportional assessment (COPRAS) and technique for order of preference by similarity to ideal solution (TOPSIS). Afterwards, COPELAND algorithm is exploited to generate a consensus and distinct ranking of material alternatives. Eventually, Spearman’s rank correlation analysis is used to evaluate the rankings obtained from the MCDM algorithms. Five numerical examples in diverse fields of material selection are tackled to examine the features and efficiency of the developed integrated model. Results illustrated that the developed model was able to solve the five material selection problems efficiently. On the other hand, no individual MCDM algorithm was able to solve all the assigned material selection problems. For instance, CODAS and TOPSIS only succeeded in solving one and two material selection problems, respectively. It was also inferred that notable differences and perturbations are encountered between the rankings of MCDM algorithms in the first, third, fourth and fifth numerical examples, which necessitates the implementation of COPELAND algorithm. It was also revealed that the highest correlation lied between COPRAS and WPM with an average Spearman’s rank correlation coefficient of 92.67%. On the other hand, the correlation between TOPSIS and CODAS attained the lowest rank with an average Spearman’s rank correlation coefficient of 18.95%. Results also demonstrated that COPRAS accomplished the highest Spearman’s rank correlation coefficient with 59.54%. Hence, it is the most efficient MCDM algorithm among the five algorithms which can serve as a reference for solving material selection problems. It can be also deduced that CODAS and TOPSIS are not advised to be implemented in solving similar material selection problems.

17005 Background: The on-board megavoltage (MV) computed tomography (CT) capabilities of a Tomotherapy unit were used to obtain the daily MVCT images of lung cancer patients. For daily patient alignment, differences between the MVCT scan and planning CT were resolved by calculating the necessary couch shifts in the X = mediolateral, Y = craniocaudal, and Z = anteriorposterior directions. Daily shifts were analyzed. Methods: 583 alignments from 36 patients with lung cancer were available for analysis. The systematic (Σ) and random (σ) errors were calculated and a covariate analysis was performed with tumor size, Karnofsky Performance Score (KPS), and presence of atelectasis. Two error minimization strategies were applied to the data - 1) shifts from fraction 1 were subtracted from subsequent shifts, and 2) the average of shifts 1–3 were subtracted from shifts 4 onward. Σ and σ were calculated for each of the 3 data sets and applied to van Herk’s margin recipe 2.5 Σ + 0.7σ. The mean, standard deviation, and standard error of the magnitude shifts for 13 patients who each received 23 fractions were analyzed by Spearman’s rank correlation test for the relationship between shift magnitude and fraction number. Results: The presence of atelectasis was significantly related to a smaller σ in millimeters, 2.8 ± 0.08 vs. 3.5 ± 0.09 (p = 1.1 × 10−8). The other covariates were not significantly related to set-up error. The 2nd error minimization strategy decreased Σ in the X, Y, and Z directions from 4.7 ± 0.6, 5.8 ± 0.9, 4.9 ± 0.6 to 2.1 ± 0.1, 4.2 ± 0.5, 3.4 ± 0.3 (p = 2.0 × 10−5, 0.13, 0.02) respectively. Calculated margins from van Herk’s equation for all data reported as (x, y, z) in mm were (13.8, 19.6, and 15.9). For strategies 1 and 2 respectively, calculated margins were reduced by (27.2%, 11.5%, 10.6%) and (46.7%, 21.5%, 23.2%). The mean magnitude of isocenter shift and the standard deviation were found to increase with fraction number (p = 1.0 × 10−6 and 5.0 × 10−5 respectively). Conclusion: The error correction strategies significantly reduced Σ but did not reduce the margins dramatically. Drift in accuracy during a long treatment course and an inability to identify subgroups of patients based on our covariates who may not need daily imaging suggests that daily image verification + correction will help reduce error and margins. No significant financial relationships to disclose.

Purpose. This study aimed to evaluate climatic data, including mean temperature, relative humidity, and rainfall, and their association with malaria incidence throughout Thailand from 2012 to 2017. The correlation of climatic parameters including temperature, relative humidity, and rainfall in each province and the weekly malaria incidence was analyzed using Spearman’s rank correlation. The results showed that the mean temperature correlated with malaria incidence (p value < 0.05) in 44 provinces in Thailand. These correlations were frequently found in the western and southern parts of Thailand. Relative humidity correlated with malaria incidence (p value < 0.05) in 35 provinces. These correlations were frequently found in the northern and northeastern parts of Thailand. Rainfall correlated with malaria incidence (p value < 0.05) in 38 provinces. These correlations were frequently found in the northern parts and some western parts of Thailand. The impacts of the mean temperature, relative humidity, and rainfall were observed frequently in specific provinces, including Chiang Mai, Chiang Rai, Trat, Kanchanaburi, Ubonratchathani, and Si Sa Ket. This is the first study to report areas where climatic data are associated with malaria incidence throughout Thailand from 2012 to 2017. These results can map out the climatic change process over time and across the country, which is the foundation for effective early warning systems for malaria, public health awareness campaigns, and the adoption of proper adaption measures that will help in malaria detection, diagnosis, and treatment.
