Authors: Saini Malkiat S. , Raina Rifat H. , Khan Zakir H. 
Published: May 2018

ABSTRACTBombus rufofasciatusSMITH is a Tibetan species, widely distributed in the Oriental region. It is a medium tongued species abundant in both the north-east and north-west Indian Himalaya, covering an altitude range from 2400 to 4200 m. Because of its abundance and very wide distribution, it is associated with a sizeable number of host plants. Males and workers are similar in colour pattern, but the queen is a little different. The species shows a preference for highaltitude mountain slopes and is found in abundance in the open meadows of Affarwatt, Sheeshnag, Daksum, the Razdan Pass and the Lahul-spiti Valley of Himachal Pradesh in the north-western Himalaya. For preference it forages onAconitumspp. (Ranunculaceae),Trifoliumspp. (Papilionaceae),Cirsiumspp. (Asteraceae) and certain members of Lamiaceae. Due emphasis has been laid on its detailed taxonomic descriptions, synonymy, host plants, pollination ecology, distribution pattern and illustrations. 51 food plants of this species have been recorded for the first time from the areas under study.

Abstract
The moss Pleurozium schreberi was used to evaluate the emission of polycyclic aromatic hydrocarbons (PAHs) at Polish cemeteries on the All Saints' Day, when Poles traditionally light candles and candle lamps in memory of the deceased. Moss samples were exposed for 7 days at 4 cemeteries and, for comparison, in a city centre and in a rural area. During exposition, the mean content of 16 monitored PAHs in the samples increased by 455 ng/g at the cemeteries and by 689 ng g-1 in the city centre. In the rural area, the samples showed no statistically significant changes. PAHs whose content increased only in the moss samples exposed at the cemeteries included naphthalene, pyrene, benzo[b]fluoranthene together with benzo[k]fluoranthene, benzo[g,h,i]perylene, indeno[1,2,3-cd]pyrene and dibenzo[a,h]anthracene. The concentrations of other PAHs increased in samples exposed in the city centre and at two cemeteries located in the suburban areas. The results presented confirm the possibility of using mosses in biomonitoring of PAHs.
The Usefulness of Prebiotics and Probiotics in Modern Poultry Nutrition: a Review / Przydatność prebiotyków i probiotyków w nowoczesnym żywieniu drobiu – przegląd
Authors: Alloui Mohamed Nabil , Szczurek Witold , Świątkiewicz Sylwester 
Published: May 2018

Abstract
A probiotic is a culture of live microorganisms that can manipulate and maintain a beneficial microflora in the gut. Prebiotics are nondigestible feed ingredients that can positively affect the animal organism by stimulating the activity and growth of beneficial native bacteria in the gastrointestinal tract and eliminate the pathogenic ones. Some studies have shown their beneficial effects when they have been used separately or simultaneously in the form of synbiotics, to obtain enhanced mutual effect. These supplements were proposed with success as alternatives to antibiotic growth-promoting feed additives but further studies are needed to better understand their mode of action and effects. This review article presents growing interest in using these antibiotic alternatives, the potential mechanism of their action in the live organism, and discusses some recent data on the effects of these supplements in poultry nutrition.

Published: May 2018

Abstract
The aim of this study was to characterize the activity of Polish Milk Sheep 05 ewes housed in the indoor system. One group of 28 animals was observed. The observations lasted 227 hours and were conducted during day and night. The activity of each ewe was recorded every 10 minutes. The observed sheep rested for most of the day. Their activity increased at dawn, during milking (and feeding) and after green forage was provided in the afternoon. The time of feeding was mostly dependent on human activities. Rumination always occurred after the feed was offered. Sheep mainly slept lying down after milking and at night. REM (Rapid Eye Movement) sleep was observed. There were statistically significant (P≤0.05) differences in individual forms of behaviour (moving, standing, lying, feeding and ruminating) between different times of the day. In conclusion, the activity pattern of the indoor-housed ewes resembled that of pastured ruminants, but it was also strongly influenced by farm staff (milking, feeding, etc.).
Feeding Corn Distillers Dried Grains With Solubles (Ddgs) And Its Effect On Egg Quality And Performance Of Laying Hens / Zastosowanie DDGS z kukurydzy w żywieniu kur niosek i jego wpływ na jakość jaj i wyniki produkcyjne

Published: May 2018

Abstract
The purpose of this experiment was to determine the effect of corn DDGS as a feed ingredient on egg quality and performance of laying hens. The experiment was conducted in three feeding groups of 100 hens each (10 replicates of 10 layers). ISA Brown laying hens were administered a feed mixture containing 15% (E1) or 20% (E2) corn DDGS for 18 weeks. The hens from the control group (C) received a standard diet based on soybean meal as the main protein source only. Laying performance, average egg weight, average daily feed intake and feed conversion ratio were recorded over the study period. Egg quality traits (egg weight, thick albumen quality, yolk colour, yolk content, shell content and shell thickness) were evaluated twice: at the start and at the end of the experiment. On both dates, all daily laid eggs from each group were analysed, i.e. 90, 93 and 92 eggs from groups C, E1 and E2, respectively at 31 weeks, and 92, 94 and 81 eggs, respectively at 48 weeks of age. Compared to the other groups, the hens from group E2 (20% DDGS) were characterized by a slight - though statistically significant (P≤0.01) - decrease in laying performance and by a higher FCR value. The content of DDGS in the feed mixture had no significant effect on mean egg weight nor on daily feed intake. At the end of the experiment, the eggs laid by the hens from group E2 were characterized by significantly poorer (P≤0.01) albumen and shell quality. Yolk colour in both experimental groups was significantly darker (P≤0.01) than in the C group. The 15% addition of corn distillers dried grains with solubles to feed mixtures for commercial flocks of laying hens is advisable. At corn DDGS addition exceeding 15%, a slight decrease in production results and deterioration in selected parameters of egg quality shall be expected.
Mixed noble gas effect on cut green peppers
Authors: Raymond L.V. , Zhang M. , Karangwa E. , Chesereka M.J. 
Published: May 2018

Abstract
Increasing attempts at using gas which leads to hydrate formation as a preservative tool in fresh-cut fruits and vegetables have been reported. In this study, changes in some physical and biochemical properties of fresh-cut green peppers under compressed noble gas treatments were examined. Mixed argonkrypton and argon treatments were performed before cold storage at 5°C for 15 days. Mass loss and cell membrane permeability were found to be the lowest in mixed argon-krypton samples. Besides, a lower CO2 concentration and vitamin C loss were detected in gastreated samples compared to untreated samples (control). While the total phenol degradation was moderately reduced, the effect of the treatment on polyphenoloxidase activity was better at the beginning of the storage period. The minimum changes in quality observed in cut peppers resulted from both mixed and gas treatment alone.

Published: May 2018

Abstract
In this paper, the analysis of the possibilities of using Digital Image Correlation (DIC) based on Graphics Processing Unit (GPU) for strain analysis in fatigue cracking processes is presented. The basic assumption for the discussed displacement and strain measurement method under time variable loads was obtaining high measurement sensitivity by simultaneously minimizing the measurement time consumption. For this purpose special computing procedures based on multiprocessor graphic cards were developed, which significantly reduced the total time of displacement and strain analysis. The developed digital procedure for correlation of images has been used for an example of displacement analysis in the method of fatigue crack propagation testing in airplane riveted joints. In this paper are presented the results of the researches of the team run by professor Antoni Zabłudowski

Evaluation of Synthetic Gypsum Recovered via Wet Flue-Gas Desulfurization from Electric Power Plants for Use in Foundries
Authors: Biernacki R. , Haratym R. , Kwapisz J. 
Published: May 2018

Abstract
This article investigates possible use of waste gypsum (synthetic), recovered via flue-gas desulfurization from coal-fired electric power plants, in foundries. Energy sector, which in Eastern Europe is mostly composed from coal-fired electric power plants, is one of the largest producers of sulfur dioxide (SO2).
In order to protect the environment and reduce the amount of pollution flue-gas desulfurization (FGD) is used to remove SO2 from exhaust flue gases of fossil-fuel power plants. As a result of this process gypsum waste is produced that can be used in practical applications.
Strength and permeability tests have been made and also in-depth analysis of energy consumption of production process to investigate ways of preparing the synthetic gypsum for casting moulds application. This paper also assesses the chemical composition, strength and permeability of moulds made with synthetic gypsum, in comparison with moulds made with traditional GoldStar XL gypsum and with ceramic molds. Moreover examination of structure of synthetic gypsum, the investigations on derivatograph and calculations of energy consumption during production process of synthetic gypsum in wet flue-gas desulfurization were made.
After analysis of gathered data it’s possible to conclude that synthetic gypsum can be used as a material for casting mould. There is no significant decrease in key properties, and on the other hand there is many additional benefits including low energy consumption, decreased cost, and decreased environmental impact.
New Look at the Process of Reclamation of Moulding Sands
Authors: Dobosz S.M. , Major-Gabryś K. , Hosadyna M. 
Published: May 2018

Abstract
This paper presents a new perspective on the issue of reclamation of moulding and core sands. Taking as a premise that the reclamation process must remain on the surface of grains some not separated binding materials rests, it should be chosen the proper moulding sand’s composition that will be least harmful for the reclaim quality. There are two different moulding and core sands taken into examinations. The researches prove that a small correction of their compositions (hardener type) improves the quality of the received reclaims. Carried out in this article studies have shown that such an approach to the problem of reclamation of the moulding and core sands is needed and reasonable.

Authors: Kamińska J. , Dańko J. 
Published: May 2018

Abstract
The results of investigations of the granulation process of foundry dusts generated in the dry mechanical reclamation process of used sands, where furan resins were binders are presented in the paper. Investigations concerned producing of granules of the determined dimensions and strength parameters.
Granules were formed from the dusts mixture consisting in 50 mass% of dusts obtained after the reclamation of the furane sands and in 50 mass % of dusts from sands with bentonite. Dusts from the bentonite sands with water were used as a binder allowing the granulation of after reclamation dusts from the furane sands.
The following parameters of the ready final product were determined: moisture content (W), shatter test of granules (Wz) performed directly after the granulation process and after 1, 3, 5, 10 days and nights of seasoning, water-resistance of granules after 24 hours of being immersed in water, surface porosity ep and volumetric porosity ev. In addition the shatter test and water-resistance of granulate dried at a temperature of 105°C were determined.
Investigations were performed at the bowl angle of inclination 45°, for three rotational speeds of the bowl being: 10, 15, 20 rpm.
For the speed of 10 rpm the granulation tests of dusts mixture after the preliminary mixing in the roller mixer and with the addition of water-glass in the amount of 2% in relation to the amount of dust were carried out.
The obtained results indicate that the granulator allows to obtain granules from dusts originated from the reclamations of moulding sands with the furane resin with an addition of dusts from the bentonite sands processing plants.

Published: May 2018

Abstract
The subject of this study is the presentation of relation between the degree of structure fineness and ultrasonic wave damping coefficient for the high-zinc aluminium alloys represented in this study by the sand mould cast alloy Al - 20 wt% Zn (AlZn20). The studied alloy was refined with a modifying (Al,Zn)-Ti3 ternary master alloy, introducing Ti in the amount of 400 pm into metal. Based on the analysis of the initial and modified alloy macrostructure images and ultrasonic testing, it was found that the addition of (Al,Zn)-Ti3 master alloy, alongside a significant fragmentation of grains, does not reduce the coefficient of ultrasonic waves with a frequency of 1 MHz.

Authors: Macků M. , Horáček M. 
Published: May 2018

Abstract
The research focused on the production of prototype castings, which is mapped out starting from the drawing documentation up to the production of the casting itself. The FDM method was applied for the production of the 3D pattern. Its main objective was to find out what dimensional changes happened during individual production stages, starting from the 3D pattern printing through a silicon mould production, wax patterns casting, making shells, melting out wax from shells and drying, up to the production of the final casting itself. Five measurements of determined dimensions were made during the production, which were processed and evaluated mathematically. A determination of shrinkage and a proposal of measures to maintain the dimensional stability of the final casting so as to meet requirements specified by a customer were the results.

Influence of Blowing of Argon on the Cleanness of Steel
Authors: Pribulová A. 
Published: May 2018

Abstract
The mechanical properties of steel components are controlled by the chemical composition and mechanical treatment to which the steel is submitted. Non-metallic inclusions have a very high influence on the steel quality but secondary metallurgy enables to reduce their content in the steel. Possibilities of secondary metallurgy are relatively extensive but financial situation in Slovak foundries does not enable to make investments in secondary metallurgy in the near future. Accessible means for influencing of steel quality is injection of an inert gas.
Main goal of experiments described in the article was verify the influence of blowing of argon into the steel in an electric induction furnace on its cleanness. Duration and flow-rate of argon blowing have a very clearly influence on the final content of non-metallic inclusions. Minimum time of argon blowing necessary for reducing of content of non-metallic inclusions in one tonne electric induction furnace was more than 6 minutes and recommended argon flow rate was 10 litters per minute.

Authors: Pribulová A. , Futáš P. 
Published: May 2018

Abstract
Foundry dust from blasting and grinding of castings contain a high amount of iron, ergo it is possible its recycling in foundry process. Dust was compacted by briquetting, two kinds of briquettes were prepared (A contained 95% magnetic part of dust from casting blasting +5% bentonite and B contained 95% mixture of dust from casting grinding and magnetic part of dust from casting blasting + 5% bentonite) and used as a part of charge into the electric induction furnace. It was found that addition of briquettes has had an influence of a chemical composition of cast iron above all on content of sulphur, phosphorus and silicon. It was not reflected in decrease in tensile strength and in microstructure. Yield of metal from briquettes was not lower then 70%.
Comparison of Energy Consumption in the Classical (PID) and Fuzzy Control of Foundry Resistance Furnace
Authors: Ziółkowskia E. , Śmierciak P. 
Published: May 2018

Abstract
Foundry resistance furnaces are thermal devices with a relatively large time delay in their response to a change in power parameters. Commonly used in automation classical PID controllers do not meet the requirements of high-quality control. Developed in recent years, fuzzy control theory is increasingly being used in various branches of economy and industry. Fuzzy controllers allow to introduce new developments in control systems of foundry furnaces as well. Correctly selected fuzzy controller can significantly reduce energy consumption in a controlled thermal process of heating equipment. The article presents a comparison of energy consumption by control system of foundry resistance furnace, equipped with either a PID controller or fuzzy controller optimally chosen.
