A substantial amount of the mustard and a small amount of the canola seed produced in the prairie provinces in 1983 was downgraded due to excessive content of insect frass. Because the frass was similar in size to the seed, much of it was not removed by the usual cleaning processes. Most seriously affected was mustard seed which has a contamination limit of 1 frass pellet per 500 g for grade Nos. 1, 2 and 3 Canada and 0.005% by weight for No. 4 Canada (Can. Grain Comm. 1983). Initially the limit for canola was 0.02% by weight based on tolerances established for rodent (vertebrate) excreta. Because insect (non-vertebrate) excreta is less detrimental than rodent excreta, the limits for non-vertebrate excreta in canola marketed within Canada were increased to 0.1%, 0.2% and 0.3% for grades No. 1, 2 and 3 respectively (per. comm., L. Sequin, Deputy Director, Standards and Technology, Canadian Grain Commission). The previous limit of 0.02% remains in effect for canola entering the export market. Similar consideration was given to revising the limit for insect excreta in mustard seed but no change was made because the quality criteria are quite different; canola is extracted for its oil whereas mustard seed may undergo little processing before being consumed.

Ammoniation (NH3) of canola seed (CS) containing wild mustard seed (WMS) present as a contaminant resulted in reduction of CS glucosinolates but not of WMS hydroxybenzyl glucosinolate or lysine contents. Feeding diets containing 25% CS including 0, 3, 6 and 9% WMS to crossbred barrows from 23 to 57 kg had no effects on average daily gain (ADG) or daily feed intake (FI) but feed:gain ratio (FG) was poorer. Serum triiodothyronine (T3) was unaffected but thyroxine (T4) was depressed by WMS, a result of hydroxybenzyl glucosinolate intake. FI was improved by NH3. This was attributed to reduced concentrations of sinapine and glucosinolates in CS and WMS. Barrows fed from 57 to 100 kg liveweight showed no effect of dietary level of WMS on ADG or FG but 7.2 and 10.8% WMS resulted in leaner carcasses than with 0% WMS. Use of 30% CS in the diet, regardless of WMS level, resulted in fatty acid changes in backfat compared with the control diets. Fatty acids C14, C16, C16:1 and C18 were reduced and C18:1, C18:2 and C18:3 were increased by consuming diets containing 10–12% oil from CS and WMS. Gilts (57–100 kg) fed diets containing 0.2 and 10.5% WMS in CS fed at 30% of the diet had similar ADG but gilts fed the high WMS diet produced leaner carcasses. Key words: Canola seed, wild mustard, pigs, feeding, glucosinolates, fatty acids

Research was conducted at two sites near Brandon, Manitoba, in 1990 and 1991 to determine the influence of time of removal of wild mustard from triazine-tolerant (TT) or triazine-susceptible (TS) canola and the effects of wild mustard seed contamination on canola seed yield and oil characteristics. Wild mustard was removed by either cyanazine or ethametsulfuron at the two-to-four-leaf or the four-to-eight-leaf stage of wild mustard in each of six canola cultivars. Wild mustard decreased harvested seed yield of canola, and the presence of wild mustard seed in harvested canola seeds increased meal glucosinolate content compared with that of the weed-free check. Canola yield was greater than that of the untreated check when wild mustard was removed at either the two-to-four-leaf or the four-to-eight-leaf stage. Canola seed yield was reduced compared with that of the weed-free check when wild mustard was allowed to compete with canola until the four-to-eight-leaf stage. Meal protein content was decreased by either wild mustard competition or the presence of wild mustard seed in the samples in 1991 but not in 1990. Canola seed samples contaminated with wild mustard seed had reduced oil and oleic acid content at both sites. Wild mustard competition reduced canola oil and oleic acid content of the two TT cultivars more than it did those of TS cultivars. The presence of wild mustard seed (but not interference from wild mustard) increased the linolenic and erucic acid content of the extracted oil. Key words: Cyanazine, ethametsulfuron, oleic acid content, glucosinolate content, erucic acid content

Introduction. Nowadays osteopathy is an offi cial medical specialty. Many years of experience accumulated by osteopathic physicians in our country have proven its effectiveness. The analysis of research papers of those countries where osteopathy is widely used allows to draw the following conclusion: osteopathy is one of the least dangerous therapeutic methods provided that patients deal with well-trained and certifi ed specialists who work in the frame of possibilities of osteopathy. Due to the intensive development of this specialty in Russia it is necessary to provide scientifi c justifi cation to organizational and methodological approaches aimed at ensuring effective and high-quality osteopathic care to the population.Goal of research - to develop proposals in order to improve the quality and effectiveness of osteopathic care provision for the population, taking into account the current situation in health care.Materials and methods. Authors used the following research methods: historical and medico-organizational analysis, literary data analysis, content analysis as well as methods of descriptive statistics.Results. The research presents characteristics of clinics declaring osteopathic care provision, as well as qualities of osteopathic physicians. It also describes patients seeking osteopathic care, and sources of information they use.Conclusion. Authors propose a number of measures aimed at improving the availability and effectiveness of osteopathic care for patients such as training of doctors, creating of regulatory documents, developing quality criteria for osteopathic care provision and popularization of osteopathy among patients.

The existence of big data of Indonesian FDI (foreign direct investment)/ CDI (capital direct investment) has not been exploited somehow to give further ideas and decision making basis. Example of data exploitation by data mining techniques are for clustering/labeling using K-Mean and classification/prediction using Naïve Bayesian of such DCI categories. One of DCI form is the ‘Quick-Wins’, a.k.a. ‘Low-Hanging-Fruits’ Direct Capital Investment (DCI), or named shortly as QWDI. Despite its mentioned unfavorable factors, i.e. exploitation of natural resources, low added-value creation, low skill-low wages employment, environmental impacts, etc., QWDI , to have great contribution for quick and high job creation, export market penetration and advancement of technology potential. By using some basic data mining techniques as complements to usual statistical/query analysis, or analysis by similar studies or researches, this study has been intended to enable government planners, starting-up companies or financial institutions for further CDI development. The idea of business intelligence orientation and knowledge generation scenarios is also one of precious basis. At its turn, Information and Communication Technology (ICT)’s enablement will have strategic role for Indonesian enterprises growth and as a fundamental for ‘knowledge based economy’ in Indonesia.
