Theoretical Bounds in Minimax Decentralized Hypothesis Testing

Minimax decentralized detection is studied under two scenarios: with and without a fusion center when the source of uncertainty is the Bayesian prior. When there is no fusion center, the constraints in the network design are determined. Both for a single decision maker and multiple decision makers, the maximum loss in detection performance due to minimax decision making is obtained. In the presence of a fusion center, the maximum loss of detection performance between with- and without fusion center networks is derived assuming that both networks are minimax robust. The results are finally generalized.Comment: Submitted to IEEE Trans. on Signal Processin

Comparison of feed value of Amaranthus powellii Willd. forage to some roughage feeds

The aim of this study was to compare the chemical composition, in vitro digestibility, protein and energy value, roughage value of Amaranthus powellii Willd. forage to the most commonly used alfalfa hay and wheat straw in ruminant nutrition. Amaranthus powellii Willd. forage has the potential to be a third quality roughage according to its relative feed value assessment of 104.55 +/- 0.67. In addition, the relative forage quality assessment developed for feeding dairy cattle was 97.73 +/- 0.05 for Amaranthus powellii Willd. forage, which had a higher the relative forage quality value than alfalfa hay and wheat straw, and it can be used for feeding dairy or fattening cattle. However, it has been generally recommended that Amaranth be given either by grazing at its early flowering time or via silage due to the oxalic acid and nitrate salts. Amaranthus powellii Willd. forage should also be determined nitrate, amino acids, and other antinutritional factors before studied in vivo as hay or silage

ANALYSIS AND APPLICATION OF A NEW MARITIME CONTAINER LINE: A CASE STUDY

Marine container transportation has shown important developments during recent years. Due to increased demands for such transportation, the related companies have to enlarge their capacities and establish new lines. The most important criterion to put in a new line is the customer’s demand for such a line under marketing conditions. There would be no commercial significance for the supply if the demand is insufficient. The demand can be calculated by the present market, marketing research and cargo statistics between the two ports involved. Marketing research consists of the phases related to identify the targets and the problems, doing the research, developing the plan, collecting and analyzing the data. Another step when establishing a new line is the itinerary of the line and also which ports will be used for the line. Furthermore the present equipment of the ports, technology and possibilities play important role in the selection of the ports. In this research the following aspects have been discussed; the factors which should be considered while the decision is being taken to establish a new container line; analysis of the operation costs; financial analyses and result for the first 5 voyages of the new container line which was established according to certain assumptions and acceptances

The effects of dietary hot pepper capsicum annuum waste powder supplementation on egg production traits of Japanese quail layers

This study was conducted to evaluate the effects of different levels of dietary hot pepper (Capsicum annuum L.) waste supplementation on egg production performance and quality in Japanese quail hens (Coturnix coturnix japonica). A total of 192, seven-weekold Japanese quail layers were divided into 4 treatment groups of similar mean weight (304±0.5 g), each comprising 12 subgroups (including 1 male and 3 females). Treatment birds were fed on experimental basal layer diet supplemented with 1, 2 or 4 g hot pepper waste powder (HPWP) per kg diet. The laying performance was determined by recording feed intake, egg weight, daily egg production, and biweekly egg quality. Results showed that HPWP supplementation to layer diet did not have any significant (P>0.05) effects on body weight and feed conversion ratio, while it had significant effects on feed intake (P<0.01), and laying egg weight, average egg weight, total egg yield (P<0.05). A 2 g HPWP supplementation resulted in the highest total egg yield (P<0.05) with quadratic effects on egg shape index (P<0.05) and albumen pH (P<0.01). According to the values in the study, the egg shape index of 2 g HPWP group was circular and; therefore, attractive to consumers. We highly recommend the non-economic value of 2 g/kg supplementation of hot pepper waste powder, especially for egg production. To conclude, HPWP can be used for quail layer diets due to its beneficial effects on egg quality since it is an economic and easy agricultural by-product obtained from red pepper paste industry waste. © 2020, Universidade Federal de Santa Maria.

Insecticidal activity of fatty acid-rich Turkish bryophyte extracts against sitophilus granarius (coleoptera: curculionidae)

This work was supported by grants from Cankiri Karatekin University and the State Planning Organization, Turkey (Project No: 2010K120720). The authors would also like to thank Turkish Republic Ministry of Forestry and Water Affairs, General Directorate of Nature Protection and National Parks for permission to collect the mosses Dicranum scoparium and Hypnum cupressiforme from Ilgaz Mountain National Park. Finally, the authors thank Bianka Martinez for grammatical revision of the manuscript.The composition of fatty acids and insecticidal effects was performed for the Turkish mosses Dicranum scoparium, Hypnum cupressiforme, Polytrichastrum formosum, Homalothecium lutescens and the Turkish liverwort Conocephalum conicum. All structures were determined by means of gas chromatography and gas chromatography-mass spectrometry techniques. The determination of fatty acids was done using a simple and mild method that utilized different solvent extractions ranging from nonpolar to polar solvents (hexane, dichloromethane, chloroform, ethyl acetate and methanol, respectively), and the samples were powdered with and without liquid nitrogen. The correlations between the saturated and unsaturated fatty acid contents depending on the solvent polarity and their crushing process by liquid nitrogen were observed. The insecticidal activity of the bryophytes was analyzed by using the methanol, hexane and esterified methanol extracts. The hexane extracts of Polytrichastrum formosum showed the highest insecticidal activity (70.33%) against Sitophilus granarius. Contact toxicity activities of lauric, myristic and palmitic acids besides single dose studies of the solvent extracts were carried out. The highest mortality rate (53.34%) was obtained from the myristic acid among the tested pure fatty acids. The activities of palmitic and lauric acids were 17.75% and 4.32%, respectively

Short and long term outcomes of primary angioplasty in patients aged 75 years and over

The treatment of elderly patients with ST segment elevated myocardial infarction (STEMI) remains controversial. This study aimed to investigate the effects of primary angioplasty in elderly patients on in-hospital and long term major adverse cardiac events (MACE).Materials and methods: From October 2003 to March 2008, we retrospectively enrolled 220 patients aged 75 years and over with STEMI who underwent primary angioplasty. Patients’ characteristics, in-hospital and long term events were recorded.Results: Male/Female ratio of patients was 129/91 and mean age was 78.7 ± 3.6 (range, 75-97) years, and 58.6% of male). Of these patients 29.2% were diabetics, 69.8% were hypertensive, 34.4% were smoker and 43.5% were anemic at admission. Anterior myocardial infarction was diagnosed in 52.3% of patients. Mean pain-balloon time was 222 ± 116 minutes. Eighty two (38.2%) of these 220 patients had three-vessel disease and 12 (5.7%) were diagnosed as cardiogenic shock. Procedural success was observed in 79.6% of patients. Heart failure was observed 27.7% in hospital and intra aortic pump was used in 14.5% of patients. There was no significant difference between age groups in long term major cardiac events and in hospital mortality. Diabetes, leukocyte count at admission and in hospital heart failure were independent predictors of short term MACE and low hemoglobin level at admission and peak CKMB levels were independent predictors of long term MACE.Conclusions: Primary angioplasty in patients aged 75 years and over seems to be associated with low procedural complication, high procedural success, improved short and long term survival
