Analysis of supply chain management in the construction industry on the example of Solmat Hanusiak Company

Praca poświęcona jest zarządzaniu łańcuchem dostaw na przykładzie hurtowni materiałów budowlanych. Zarządzanie łańcuchem dostaw pomimo, że jest stosunkowo nową dziedziną zarządzania staje się stopniowo standardem w zarządzaniu przedsiębiorstwem. Znaczenie prawidłowego zarządzania łańcuchem dostaw staje się coraz bardziej doceniane przez przedsiębiorstwa różnych branż. Pierwszy i drugi rozdział stanowi bazę teoretyczną. W rozdziale pierwszym przedstawiono zagadnienia współczesnej logistyki. Rozdział drugi jest poświęcony zarządzaniu łańcuchem dostaw. W trzecim rozdziale została zaprezentowana firma Solmat Hanusiak Sp. komandytowa. Szczegółowo omówiono strukturę firmy, logistykę i współpracę z kontrahentami. W rozdziale czwartym przedstawiono analizę zarządzania łańcuchem dostaw z zastosowaniem metodologii badań. W pracy wykorzystano literaturę dotyczącą tematu pracy, a także materiały dotyczące firmy.The thesis is dedicated to supply chain managament on the example of contrauction industry. Supply chain managament is new field of managament science but it is becoming the standard in the managament of the company. The meaning of proper supply chain managament becomes increasingly appreciated by different branches. The first and second chapter provide a theoretical background. The first chapter presents the modern logistics issues. The second chapter is dedicated to supply chain managament. The third chapter presents Solmat Hanusiak Company. It describes in detail the structure of the company, its logistics and partnership. The fourth chapter presenst the analysis of supply chain management using the research. The study was based on a series of books, as well as materials from Solmat Hanusiak Company

A Comparative Study of Selected Gut Bacteria Abundance and Fecal pH in Bodybuilders Eating High-Protein Diet and More Sedentary Controls

Bodybuilders tend to overeat their daily protein needs. The purpose of a high-protein diet is to support post-workout recovery and skeletal muscle growth; however, its exact impact on gut microbiota still remains under investigation. The aim of this study was to assess the differences in selected gut bacteria (Faecalibacterium prausnitzii, Akkermansia muciniphila, Bifidobacterium spp., and Bacteroides spp.) abundance and fecal pH between the group of amateur bodybuilders and more sedentary control group. In total, 26 young healthy men took part in the study, and their daily nutrients intake was measured using a dietary interview. Real-time PCR was used to assess the stool bacteria abundance. Both groups reported fiber intake within the recommended range, but bodybuilders consumed significantly more protein (33.6% ± 6.5% vs. 22% ± 6.3%) and less fat (27.6% ± 18.9% vs. 36.4% ± 10%) than controls. Study results showed no significant differences in terms of selected intestinal bacteria colony forming unit counts. Significantly higher fecal pH in the bodybuilders’ fecal samples was observed in comparison to the control group 6.9 ± 0.7 vs. 6.2 ± 0.7. Gut microbiota composition similarities could be a result of appropriate fiber intake in both groups

No changes in the abundance of selected fecal bacteria during increased carbohydrates consumption period associated with the racing season in amateur road cyclists

Background Cyclists often use high-carbohydrate, low-fiber diets to optimize the glycogen stores and to avoid the gastrointestinal distress during both, the trainings and the competitions. The impact of such dietary changes on gut microbiota is not fully known. Methods We assessed the abundances of Faecalibacterium prausnitzii, Akkermansia muciniphila, Bifidobacterium spp., and Bacteroides spp. and the fecal pH in 14 amateur cyclists during the racing season. Eleven healthy men formed the control group. Results Despite significant differences in the diet composition and physical endurance levels of amateur cyclists before the competition season (1st term) and control group (carbohydrates: 52.2% ± 4.9% vs 41.9% ± 6.6%; VO2max: 56.1 ± 6.0 vs 39.7 ± 7.7; p < 0.01; respectively), we did not observe any significant differences in studied gut bacteria abundances or fecal pH between the groups. Although the cyclists’ carbohydrates consumption (2nd term) have increased throughout the season (4.48 g/kg b.w. ± 1.56 vs 5.18 g/kg b.w. ± 1.99; p < 0.05), the studied gut bacteria counts and fecal pH remained unchanged. It seems that the amateur cyclists’ diet with increased carbohydrates intake does not alter the gut microbiota, but further research is needed to assess the potential impact of even higher carbohydrates consumption (over 6 g/kg b.w.)

Breaking tester for examining strength of consolidated starch

A new method based on the measurement of force required to break by bending a vertical column of consolidated powder was elaborated, and its results were compared with the ones obtained from the Jenike shear test. A new apparatus was built based on a vertical cylindrical chamber divided into two cylinders connected with a horizontal hinge. The apparatus was tested with samples of potato, maize and wheat starches with moisture content of 6, 12 and 17% and with the addition of a lubricant. Results of testing revealed significant differences in measured force required to rotate the upper part of the cylinder away from the lower one. The average force varied from 0.138 N for maize starch to 0.143 N for potato starch, while, for various moisture contents, the measured force varied from 0.135 N for 6% to 0.143 N for 17% mc. The results were compared with the results of a direct shear test
