The main anti-nutritive substances present in rye grains include alkylresorcinols, water-soluble pentosans, and trypsin inhibitors. The content of these compounds in the grains can be influenced by genetic factors, habitat conditions and the crop management technology used in cultivation. The aim of the study was to determine the variability of the concentration of anti-nutritive compounds in rye grains depending on the variety, weather conditions and production technology. The field research was conducted at the IUNG-PIB Experimental Station in Osiny (Poland) in three growing seasons 2010/2011, 2011/2012 and 2012/2013. The experiment was located on lessive soil, on plots of 45 m2 in three replications. The first factor was the type of production technology (integrated and intensive), while the second was a variety of winter rye. Two hybrid varieties (Brasetto, Visello) and two population varieties (Dańkowskie Diament, Kier) were included. The research showed that the content of anti-nutritive compounds in rye grains depended significantly on the genotype and weather conditions. Stress conditions during the rye growing season in 2011 and 2013 were the cause of higher synthesis of alkylresorcinols, soluble pentosans and trypsin inhibitors in rye grains. The content of alkylresorcinols and water-soluble pentosans also depended significantly on the intensity of the production technology. The higher content of these compounds was found in rye grains from intensive technology. The production technology had no significant impact on the activity of trypsin inhibitors.

The aim of the study was to compare the productive and economic effects of different production intensities of spring wheat. The study was based on the results of a two-year (2015-2016) field study, conducted at the Agricultural Experimental Station in Osiny, belonging to the Institute of Soil Science and Plant Cultivation in Pulawy. Spring wheat cultivars (Arabella and KWS Torridon) were grown using intensive and integrated technologies. The technologies studied differed in the level of mineral fertilization and chemical plant protection. The cultivation of spring wheat of the KWS Torridon cultivar according to intensive technology, as compared with cultivation under conditions of integrated technology, resulted in a significant increase in grain yield by 10.6%, respectively. On the other hand, no effect of production technology was found on the yield of the Arabella cultivar. The research showed that the technology intensity level, determined by inputs of production means, determined the structure of direct costs and profitability of spring wheat cultivars. The compared technologies ensured the profitability of spring wheat grain production. The most advantageous index of direct profitability was recorded for the Arabella cultivar grown under integrated technology.

Production Technologies

The aim of the study was to compare the production and economic effects of different winter rye depending on their production technologies. The study was carried out based on the results obtained from a field experiment conducted in two growing seasons (2018/2019 and 2019/2020). These experiments were conducted in Wielichowo Agricultural Experimental Station, belonging to the Institute of Soil Science and Plant Cultivation – the State Research Institute in Puławy (Poland). The result of the study was the determination of economic efficiency indicators for two cultivars of winter rye varieties according to production technology The technologies differed in terms of the degree of consumption of means of production. The studies showed a significant influence of production technology intensity on the yields of winter rye cultivars. Intensive technology resulted in a significant increase in grain yield. The tested cultivars yielded higher under intensive production technology. The cultivation of winter rye according to intensive technology compared to integrated technology resulted in a significant increase in grain yield . The grain yield increase for the KWS Vinetto cultivar was 0.13 t/ha, while for the Dańkowskie Granat cultivar 0.20 t/ha. Research showed that the level of production intensity determined the amount of direct costs as well as the profitability of production in a given technology. The compared technologies ensured the profitability of winter rye grain production. Both production technologies ensured the profitability of production of the tested cultivars of winter rye. The most profitable direct profitability index was characteristic for the population cultivar Dańkowskie Granat grown under the integrated technology.

Difficult Cases

Persons with a high frequency hearing loss are difficult cases for whom to find suitable amplification. We have experienced some success with this problem in our Hearing Clinics using a specially designed earmold with a hearing aid. Thirty-five cases with high frequency hearing losses were selected from our clinical files for analysis of test results using standard, vented, and open earpieces. A statistical analysis of test results revealed that PB scores in sound field, using an average conversational intensity level (70 dB SPL), were enhanced when utilizing any one of the three earmolds. This result was due undoubtedly to increased sensitivity provided by the hearing aid. Only the open earmold used with a CROS hearing aid resulted in a significant improvement in discrimination when compared with the group’s unaided PB score under earphones or when comparing inter-earmold scores. These findings suggest that the inclusion of the open earmold with a CROS aid in the audiologist’s armamentarium should increase his flexibility in selecting hearing aids for persons with a high frequency hearing loss.

Precipitation Process

The evaluation and process risk assessment of (a) lignin precipitation from black liquor, and (b) the near-neutral hemicellulose pre-extraction for recovery boiler debottlenecking in an existing pulp mill is presented in Part I of this paper, which was published in the July 2012 issue of TAPPI Journal. In Part II, the economic assessment of the two biorefinery process options is presented and interpreted. A mill process model was developed using WinGEMS software and used for calculating the mass and energy balances. Investment costs, operating costs, and profitability of the two biorefinery options have been calculated using standard cost estimation methods. The results show that the two biorefinery options are profitable for the case study mill and effective at process debottlenecking. The after-tax internal rate of return (IRR) of the lignin precipitation process option was estimated to be 95%, while that of the hemicellulose pre-extraction process option was 28%. Sensitivity analysis showed that the after tax-IRR of the lignin precipitation process remains higher than that of the hemicellulose pre-extraction process option, for all changes in the selected sensitivity parameters. If we consider the after-tax IRR, as well as capital cost, as selection criteria, the results show that for the case study mill, the lignin precipitation process is more promising than the near-neutral hemicellulose pre-extraction process. However, the comparison between the two biorefinery options should include long-term evaluation criteria. The potential of high value-added products that could be produced from lignin in the case of the lignin precipitation process, or from ethanol and acetic acid in the case of the hemicellulose pre-extraction process, should also be considered in the selection of the most promising process option.
