Lipids were sepd. from egg yolk by solvent extn. at 4°C for 15 min and by accelerated solvent extn. with MeOH, EtOH and 1-PrOH at 80-100°C and 11 MPa under N2 for 60 s. The highest extn. yield (85.68%) was achieved by conventional extn. with MeOH. The accelerated solvent extn. was most efficient (yield 60.49%) when 1-PrOH was used as solvent and process was carried out at 100°C.

Phospholipids were extd. from liophilized egg yolk with EtOH in coned, microwave field (800 W, 50 Hz). The highest yield of phospholipids (16.35%) was achieved when 8 kJ energy was supplied and the spacings between pulses were 800 ms long. The yield was however lower than that achieved during conventional chem. extn. (19.23%).

Multicomponent NPKMG, NPSCaMg and NPS fertilizers were produced and granulated at 60-90°C after addn. of superphosphate, urea-phosphogypsum and (NH4)2SO4 pulps (H2O content 22-40% by mass, pH 3.5-4.8) under pilot plant conditions. Applicability of the process for industrial granulation of fertilizers was confirmed.

PhH-contg. air was filtered at 20°C through peat-pearlite bed inoculated with selected Acinetobacter, Alcaligenes and Corynebacterim species and improved by addn. of a N, P, K and Mg as well as B, Cu, Fe, Mo and Zn-contg. fertilizer (mass load of the bed up to below 80 mg/m3s) to study the efficiency of PhH biodegrdn. The inoculation resulted in a substantial Increase in the rate of PhH removal up to above 70 mg/m3s (process efficiency near to 100%).

Introduction: Shaken Baby Syndrome (SBS) is a set of symptoms caused by shaking a child and/or by head impact trauma. SBS mostly affects children under the age of 2. Aim of the study: The aim of the study was to assess the knowledge of SBS, the causes and consequences of its phenomenon and to embed the whole issue in the context of violence and the use of corporal punishment on children. Material and methods: The method used in the research was an original questionnaire consisting of 34 questions. The study involved 458 adults; 54.8% were representatives of the medical staff and 45.2% constituted parents with children from 4 to 10 years of age. Women outnumbered male participants - they accounted for 85% of the respondents. The mean age of the study group was 36.5 years for the parents, while the average age of the medical staff was 41.7 years. Results: 45% of the respondents admitted that they had inflicted the physical punishment on their child. 46% of them had witnessed the situation when the child was a victim of physical violence in a public place. Among the respondents who witnessed the violence, 29% reacted to prevent it. 40% of the surveyed had heard of the Shaken Baby Syndrome (SBS). 21% of the people considered stated that they had shaken the child to calm it. Conclusions: 1. Almost half of the respondents use physical punishment on their children. 2. The vast majority of the respondents, including the medical staff, do not respond while witnessing physical violence being used against a child in a public place.3. The knowledge of the medical staff about the Shaken Baby Syndrome is not adequate, which is particularly alarming since the patients are young children. 4. Almost half of the respondents do not know that shaking a child can lead to a vision loss or cause the death of the child. © 2015 Polish Pediatric Society. Published by Elsevier Sp. z o.o.

In this review paper, the application of correlated CAx tools - a multi-aspect terminology used to describe the application of general engineering techniques as well as the computer aid tools for design (CAD), analysis (CAE), production (CAE) etc. has been presented. The fundamental part of the construction process was performed with the aid of the parametrical program Inventor. The verification of the functionality of the form was performed with the MSC.MARC program. The optimal mold-filling capabilities were determined in the Moldflow program. This program was also used to evaluate the influence of geometric parameters of the gating system of the mold on injection pressure and clamp force. Most of these studies were done with special consideration the criterion of minimizing the load of the mold. On the basis of the results of the performed analysis, a quarter of the geometric model of the mold was built using Inventor applications. The applied analysis method together with the MSC.MARC program allowed for the testing of the molds in terms of deformation and also permeability resulting from it. The potential sources of flashes and dangers were also indicated. The effectiveness of mold activity was analyzed taking into consideration, first and foremost, the possibility of jams occurring in the leader pin-guide bushing. On the basis of numerical analysis a construction solution for the leader pin-guide bushing has been proposed which would eliminate this most undesired phenomenon. The most suitable position as well as the required active contact length of this kinematic pair was shown. The complete geometric model of the mold was constructed according to Inventor program on the basis of the models obtained from the performed simulation studies.


The article describes courses organized for foresters in Poland in 1918-1939. It demonstrates the importance of such trainings as a supplementary education of forest rangers, timber sorters and resin extractors.
