PSIX-12 “Lamarin Saldonum” for the raising of milk production of cows

The aim of the research was to establish the effectiveness of the use of the feed additive “Lamarin Saldonum.” The feed additive contains Japanese kelp, milk thistle, to increase the milk productivity during the milking period. The studies were conducted on 40 cows of the black-and-white Holstein breed at the age of 2–4 lactation and the amount of milk for the last lactation not less than 7,500 kg. The cows were divided into 4 groups (GE1, GE2, GE3, GC) of 10 heads in each. Cows GE1, GE2, GE3 received 30 days before calving daily feed additive in doses of 0.1, 0.2, 0.3 g/kg, respectively, for 60 days. In the GC animals didn’t receive the feed additive (control group). Control milking was performed every 10 days. Using of feed additive in the ration increased milk productivity. In the 1st month of lactation, the average daily amount of milk in GC was 24.00±0.93 kg, which is 7.4%, 19.6% (P < 0.01), 7.4% less than in GE1, GE2 and GE3, respectively. In the 2nd month, the highest average daily amount of milk in GE2 and GE3, which is 13.4% (P < 0.01) and 4.6% more than the GC, respectively. In the 3rd month, the average daily amount of milk in GE1, GE2, and GE3 was 30.22±2.44 kg, 39.57±2.68 kg, 35.11±2.59 kg, respectively, which is 6.8%, 39.9% (P < 0.01), 24.1% more than in GC. The mass fraction of fat in milk in animals GE1, GE2, GE3 was 0.2–0.92%(P < 0.01) higher than in GC. In the second month of lactation, the mass fraction of protein in GE2 was higher by 0.24% (P < 0.01), in GE3–by 0.14 (P < 0.05) relative to GC. At the 3rd month of lactation, the protein content in milk was 0.29% higher in GE2 (P < 0.001) and GE3-by 0.21% (P < 0.001) than in GC.

Optimizing Treatment of Cesspool Wastewater at an Activated Sludge Plant

The purpose of this work was to determine the optimal percentage of wastewater from cesspool in the mixture of wastes subjected to treatment processes, which will not have a negative impact on the functioning of the collective treatment plant. The study was carried out over a period of two years, with 48 samples of wastewater flowing in from the sewage network and delivered with the slurry tanker collected and subjected to physical and chemical analysis. The analysis included: Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), and Total Nitrogen (TN). In addition, the study defined the daily balance of the amount of inflowing and transported wastewater. Based on the analysis carried out, it was found that the unit loads of BOD5, COD and TN in the mixture of wastewater subjected to the treatment process will be at the level of loads assumed in the project, when the share of supplied wastewater, i.e., from cesspool, will be at the level of 5% of the total amount of wastewater. Considering that in the analysed period the total average daily amount of wastewater subjected to the treatment process was 253.5 m3·d−1, the optimal amount of wastewater delivered should be 12.7 m3 in each day of the week.

Inpatient management of gamma-hydroxybutyrate withdrawal

Objectives: To describe the baseline characteristics, treatment and retention in patients electively admitted for gamma-hydroxybutyrate (GHB) withdrawal management. Methods: All patients admitted between July 2010 to June 2016 who used GHB two or more times per week with a minimum duration of 3 months were identified and data extracted by file review. Results: Twelve cases satisfied the inclusion criteria, of whom 50% were female; 75% were using GHB daily, with an average daily amount of 16 ml. Average duration of use was 60 months. All subjects were using amphetamine type stimulants and nicotine. Psychiatric comorbidity and unintentional overdose were common; 50% completed treatment. Medications used included diazepam and neuroleptic. Two patients completed withdrawal with no medications. No subject using greater than 90 ml GHB in the preceding week completed treatment. Pattern of GHB use did not predict medication requirements during withdrawal management. Conclusions: There were low numbers attending for elective treatment for GHB use. Heavier GHB use predicted poor treatment retention. Polysubstance use and psychiatric co-morbidities need consideration in treatment planning.

Analysis of hydraulic load of a wastewater treatment plant in Jasło

The paper presents an analysis of hydraulic load in a wastewater treatment plant (WTP) in Jasło. The study was based on the records of daily sewage volume entering the treatment plant within a multi-year period of 2010–2014. The analysis took into account the average daily amount of incoming sewage, the maximum daily peaking factor for the incoming sewage, changes in the sewage volume depending on specific month and day of a week, and class intervals with the greatest frequency of occurrence. The analysis revealed that the average daily volume of the sewage entering the WTP in Jasło in the investigated multi-year period was 13 045 m3·d−1. The amount of incoming sewage was variable, as evidenced by the maximum peaking factors of daily sewage inflow that ranged from 1.07 to 2.78, depending on a specific month. The sewage admission was the largest in March, May and June and on Saturdays. Sewage volume interval most often occurring at the WTP in Jasło was the one between 8 000 and 10 000 m3·d−1. The study results indicated that the facility was hydraulically underloaded.

Applying Multi-level Perceptron (MLP) neural network to analyze the importance of consumer behavior factors on new cigarette purchase price, the current price and the average daily amount of smoking, come to the results which education, income and occupation are the three most important factors, and analyzed the specific impact degree and mode of the three factors.

A METHOD FOR THE QUANTITATIVE DETERMINATION OF FECAL BACTERIA

From results of which the foregoing data form a part, it appears that the amount of bacterial nitrogen in the feces is a valuable index to intestinal conditions, and the method herein described is a simple and satisfactory one for making this determination. It involves three serial centrifugalizations of a two gram sample of the fresh feces brought into suspension in 0.2 per cent. hydrochloric acid. The bacterial suspension finally obtained is concentrated and extracted by alcohol, and nitrogen is determined in the precipitated material. The complete data on a given stool can be obtained in about five days, and one operator can take care of three or four stools in duplicate in one day. On an absolutely uniform diet of simple and easily digested food during a period of three to four weeks, the average amount of bacterial nitrogen in two subjects was found to be 53.9 per cent. of the total fecal nitrogen, and this percentage, though higher than that obtained by workers heretofore, is probably more nearly a true value for bacterial nitrogen, because no ether extraction was employed. The average daily amount of dry bacteria, calculated on the basis of the nitrogen values, is 8.27 grams.
