An Object Detection and Identification System for a Mobile Robot Control

The one of the features of mobile robot control is to detect and to identify objects in workspace. Especially, autonomous systems must detect obstacles and then revise actual trajectories according to new conditions. Hence, many solutions and approaches can be found in literature. Different sensors and cameras are used to solve problem by many researchers. Different type sensors usage can affect not only system performance but also operational cost. In this study, single camera based obstacle detection and identification algorithm was developed to control omni-drive mobile robot systems. Objects and obstacles, which are in robot view, are detected and identified their coordinates by using developed algorithms dynamically. Developed algorithm was tested on Festo Robotino mobile robot. Proposed approach offers not only cost efficiency but also short process time

Faunistik ve biyoçeşitlilik çalışmaları arasındaki fark nedir?

While faunistic studies give information about the distribution of animals in a region, the diversity (number and variety of species) studies give information about diversity of plant and animal life within a region of which they are part. In other words; faunistic studies prove the existence of animals in that habitat or region with systematically or by random sampling. The number of individuals of the sampled species is not that important. Faunistic studies are essential scientific studies, especially for the detection of new species and their introduction to the inventory. There is no doubt as to the great desirability of faunistic studies on the geographical distribution of animals. Biological diversity is the variability among living organisms from all sources (including terrestrial, marine, and other aquatic ecosystems) and the ecological complexes. This includes diversity within species (alpha), between species (beta), and of ecosystems (gamma). The importance of this description is that it draws attention to the many dimensions of biodiversity (Genetic, species, habitat, and ecosystem). Studies of biological diversity and its measurement necessarily require systematic and homogenous sampling methods. Especially when comparing two or more habitats in terms of species richness, diversity, evenness, similarity, etc. Such biodiversity indices are often used to measure the diversity in habitats destroyed by human. Four pasture ecosystems, two of which are natural and two of which are grazed by sheep and goats, were chosen as the study area in Atabey district of Isparta province. Pitfall trap and sweep net sampling methods were used in selected habitats. While the pitfall trap sampling method was applied homogeneously in the habitats, the sweep net sampling method was not applied homogeneously. The data obtained from these two sampling methods, homogeneous and non-homogeneous, were used in the calculation of biodiversity parameters.We desire to call attention in this manuscript to the differences between faunistic and biodiversity studies (specially its measurement) with reference to the previous studies.Faunistik çalışmalar, hayvanların bir bölgedeki dağılımı hakkında bilgi verirken, çeşitlilik (tür sayısı ve çeşitliliği) çalışmaları, parçası oldukları bir bölgedeki bitki ve hayvan yaşamının çeşitliliği hakkında bilgi verir. Diğer bir deyişle; Faunistik çalışmalar, sistematik veya rastgele örnekleme ile o habitatta veya bölgede hayvanların varlığını kanıtlamaktadır. Örneklenen türün birey sayısı o kadar önemli değildir. Faunistik çalışmalar, özellikle yeni türlerin tespiti ve envantere girişi için gerekli bilimsel çalışmalardır. Hayvanların coğrafi dağılımına ilişkin faunistik çalışmaların büyük arzu edildiği konusunda hiçbir şüphe yoktur. Biyolojik çeşitlilik, tüm kaynaklardan (karasal, deniz ve diğer su ekosistemleri dahil) ve ekolojik komplekslerden gelen canlı organizmalar arasındaki değişkenliktir. Bu, türler içindeki (alfa), türler arasındaki (beta) ve ekosistemlerdeki (gama) çeşitliliği içerir. Bu tanımlamanın önemi, biyolojik çeşitliliğin birçok boyutuna (Genetik, türler, habitat ve ekosistem) dikkat çekmesidir. Biyolojik çeşitlilik çalışmaları ve ölçümü, mutlaka sistematik ve homojen örnekleme yöntemleri gerektirir. Özellikle iki veya daha fazla habitatı tür zenginliği, çeşitlilik, eşitlik, benzerlik vb. açısından karşılaştırırken. Bu tür biyolojik çeşitlilik indeksleri genellikle insanlar tarafından yok edilen habitatlardaki çeşitliliği ölçmek için kullanılır. Çalışma alanı olarak Isparta ili Atabey ilçesinde ikisi doğal, ikisi koyun ve keçilerin otladığı dört mera ekosistemi seçilmiştir. Seçilen habitatlarda tuzak ve süpürme ağı örnekleme yöntemleri kullanılmıştır. Habitatlarda tuzak tuzak örnekleme yöntemi homojen olarak uygulanırken, taramalı ağ örnekleme yöntemi homojen olarak uygulanmamıştır. Biyoçeşitlilik parametrelerinin hesaplanmasında homojen ve homojen olmayan bu iki örnekleme yönteminden elde edilen veriler kullanılmıştır. Bu yazıda, daha önceki çalışmalara atıfta bulunarak, faunistik ve biyoçeşitlilik çalışmaları (özellikle ölçümü) arasındaki farklılıklara dikkat çekmek istiyoruz

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.

Bioremediation of Synthetic Prepared Domestic Wastewater with P. chrysosporium

In this study, the removal efficiencies were evaluated based on key environmental parameters such as chemical oxygen demand (COD), Total Organic Carbon (TOC), Total Nitrogen (TN), and Total Phosphorus (TP), using P. chrysosporium white rot fungus to treat synthetically prepared domestic wastewater. The research aimed to assess the suitability of bioremediation results with respect to the Urban Wastewater Treatment Regulation. The experiment was carried out over a span of 11th days, employing static 1%252F1 and 1%252F5, as well as dynamic 1%252F1 and 1%252F5 dilution ratios. The outcomes revealed varying removal efficiencies, with the highest rates observed at dynamic conditions and a 1%252F5 dilution ratio%253A 84%25 for COD, 81%25 for TOC, 73%25 for TN, and 56%25 for TP. Conversely, the lowest removal efficiencies were determined under static 1%252F1 conditions, reaching 48%25 for COD, 33%25 for TOC, 31%25 for TN, and 45%25 for TP. Based on the results, it is evident that P. chrysosporium exhibited effective bioremediation capabilities on synthetic domestic wastewater within a reasonable 11th day period. Furthermore, the results aligned with the specified limit values outlined in the Urban Wastewater Treatment Regulation. Consequently, the study highlights the efficacy of P. chrysosporium as a valuable species for biological treatment stages in urban wastewater management

Bioremediation Performance of Sphingomonas melonis and Bacillus muralis on Herbicide Diquot Dipremide-(ethylene-d4)

Bioremediation is a process that utilizes the degradation potential of microorganism to provide a cost-effective and reliable approach for pesticide biodegradation. For this purpose, chosen bacteria Sphingomonas melonis and Bacillus muralis were isolated from an agricultural soil sample. The biodegradation performance of these isolated bacteria at different Diquot Dipremide-(ethylene-d4) (DDE4) herbicide concentrations (250, 500 and 1000 ppm) was investigated under submerged culture conditions. Biodegradation performance of isolated bacteria was monitored with COD, TOC and, BOD5 reduction rates in culture medium at different incubation periods. According to the results%253B S. melonis has the highest bioremediation capacity for COD removal (91%25 at 250 ppm). For TOC, B. muralis has the highest removal rate as 82%25 at 250 ppm. On the other hand, For BOD5 at 250 ppm 85%25 S. melonis showed the best removal performance. Most effective removal rate at 250 ppm concentrations was obtained as 91%25 and 88 by S. melonis and B. muralis respectively at the end of the 216th hour for COD. Additionally, the increase in turbidity related with population dynamics at the end of the 216 th hour positively effected the bioremediation parameters included COD, TOC and BOD5 reductions. These results showed that it can be used for effective COD, TOC and BOD5 removal in S. melonis and B. muralis on DDE4 remediation

Is Glasgow prognostic score a predictor of mortality in infective endocarditis?

Objectives: The inflammation-based Glasgow prognostic score (GPS), which comprises elevated serum Creactive protein (CRP) and decreased albumin concentration, is the most valid inflammatory risk score in cancer. New prognostic markers are needed to predict high-risk infective endocarditis (IE) patients. In the present study, we investigated the in-hospital mortality estimation of GPS in infective endocarditis patients. Methods: The retrospectively designed study included 53 IE patients diagnosed according to Duke criteria. Demographic and clinical data of the patients were recorded and GPS levels were measured. Patients were divided into two groups according to in-hospital mortality outcomes. Glasgow prognostic score was rated as 0, 1, or 2 points based on serum albumin and C-reactive protein levels. Results: The nonsurvivor group was older and the number of patients with kidney failure or diabetes was higher in this group. Glasgow prognostic score was higher in the nonsurvivor group, while albumin levels were lower. Thirty-four patients died during intensive care unit follow-up, and the mean follow-up period was 24.1 ± 18.6 days. ROC analysis showed that the Glasgow prognostic score had a sensitivity of 82.4% and a specificity of 36.8% at a cut-off value of ≥ 1.5 in predicting in-hospital mortality. Chronic renal failure (OR: 6.720; 95% CI: 1.907-23.684; p = 0.003) and age (OR: 1.040; 95% CI: 1.001-1.081; p = 0.044) were the independent variables of the mortality prediction in univariate logistic regression analysis. In multivariate logistic regression analysis, only chronic renal failure (OR: 0.153; 95% CI: 0.036-0.653; p = 0.011) was found to be a significant predictor of mortality. Kaplan–Meier survival analysis revealed that long-term survival was reduced in patients with a high GPS (Log-rank: p = 0.003). Conclusions: Glasgow prognostic score level is associated with increased in-hospital mortality in IE patients. Chronic renal failure and GPS are the independent predictors of mortalit
