The research is based on the hypothesis that transport analysis of the impact of the attraction and production of planned content in the urban tissue on the wider transport network is a key method in the urban planning of large projects. The specificity of the methodological ap-proach used can be seen in the quantification of the project area and the estimation of the number of trips generated by the planned content in peak hours, as well as the expected num-ber of cars in the street network. The generation of potential trips and their distribution are determined, depending on the volume and structure of the planned content. Using the soft-ware, three possible scenarios were processed. In the conclusions, we summarize the im-portance of processing and the necessity of applying the results of transport analyses as a key method in urban and spatial planning, influencing the organization and connectivity.
In the literatures, some podoscope systems have been introduced to analyze the plantar footprint. However, there is an absence of a low complexity portable system with control capacity and trace ability of users and their results through a web application. Therefore, the objective of this study is to develop of a portable system that allows the automation of the process; reducing the errors of human character and the times of accomplishment. \nThe development methodology of the research is a cascade type that begins as an initial phase in analyzing of the requirements and restrictions of the system. Then the physical and circuit design of the platform are carried out. Once the first two stages of the methodology are complete, the algorithms of the portable system based on Android Studio, and the web application are developed under the Laravel framework. Finally, the performance of the proposed system and the analysis of the results will be presented. In this study, the footprint of 35 users and a total of 70 samples will be analyzed. The results show 74% accuracy compared to the manual method.
Numerous conducted researches in connection with the study of earthquakes have shown that electromagnetic monitoring studies have led to some important results. At present numerous studies have been conducted in this area and researches are being improved. From my research as a young researcher, it became clear that electromagnetic monitoring research is necessary, and that more important and significant results can be achieved if continuous research is conducted in this area. Thus, these studies may play a significant role in the detection of earthquake precursors.
Objective: We aimed to investigate the positive effects of low-flow sevoflurane anesthesia on emergence and recovery periods in pediatric patients undergoing adenotonsillectomy.\nMethod: Sixty children of ASA I-II aged 2-10 years who were scheduled for adenotonsillectomy were included in the study. Patients were randomly assigned to either low-flow anesthesia or high-flow anesthesia. Heart rate, mean arterial pressure, peripheral oxygen saturation, inspiratory oxygen concentration, end tidal carbon dioxide and Bispectral index values of the patients were recorded in the operating room. Spontaneous breathing effort and extubation time were recorded while emergence from anesthesia. Heart rate, mean arterial pressure, peripheral oxygen saturation, pain and agitation scores were also recorded in the recovery room. The day after surgery, the parents were called to investigate whether the unwanted effects occured.\nResults: Hemodynamic variables were not different between the groups at all times (p> 0.05). There was no difference between the groups in bispectral index values (p> 0.05). Spontaneous respiration time and extubation time were not different between the groups (p> 0.05). Pain and agitation scores were lower in low flow group (p <0.05). No side effects were observed in any of the groups.\nConclusion: We observed the positive effects of short-term low flow anesthesia in pediatric patients on recovery in the early postoperative period.
Many plant extracts have shown interesting pharmacological properties and they have become very popular as potential agents for therapeutic purposes. The present work studied the anti-proliferative potential of ethyl acetate and ethanol extracts from Diplotaxis simplex (Viv.) Spreng (Brassicaceae) flowers against MCF7 human breast-cancer and K562 human leukemia cells. The anti-obesity potential was evaluated by the inhibitory effect of flowers extracts on recombinant human pancreatic lipase. The liquid chromatography-electrospray ionization-tandem mass spectrometry analysis of the flowers extracts allowed the identification of 7 phenolic acids and 9 flavonoids. Hyperoside and quercetrin were the major identified flavonoids and coumaric acid was the major phenolic acid. The ethyl acetate extract was effective in inhibiting K562 human leukemia cells (IC50 value: 20 µg/ml) and pancreatic lipase activity (IC50 value: 0.14 mg/ml). These data suggest that D. simplex may be useful as a candidate in the treatment of obesity and the leukemia cancer.
Manganese steels are widely used material in various industries. In this paper, the effect of titanium content in chemical composition of steel on improvement of microstructure and mechanical properties of manganese steels has been investigated. The microstructure by optical, SEM and FESEM microscopy, was investigated. Also, mechanical tests such as tensile test, hardness and impact test were performed on the samples. Microscopic test results show that the presence of of titanium, reduces the segregated carbides in grain boundaries and uniform distribution of alloying elements. In presence of titanium, annealing solution heat treatment, improve the morphology of carbides and modified it to spherical shape. Alloying of manganese steels by titanium and solution heat treatment, increase hardness, impact energy and tensile strength. The results show that the chemical composition and solution treatment of manganese steels are very important and affect the mechanical properties and microstructure of manganese steels.
The principal objective of this research was synthesizing silver nanoparticles for the purpose of augmenting the sensitivity and conductivity of carbon paste electrode for determining Cd(II) and Pb(II) in discharged textile effluent. While UV-Vis, XRD and FT-IR were used to characterize the green synthesized silver nanoparticles, cyclic voltammetry was used to evaluate the electrochemical behavior of the two metals at the modified electrode relative to the unmodified electrode. Square wave anodic stripping voltammetric current showed linear dependence on the concentration in the range 5-160 ppm with determination coefficients (r) of 0.9976 and 0.99960 for Cd (II) and Pb (II), respectively. The method also showed low detection limit (0.0891ppm for Cd(II) and 0.048 ppm for Pb) making the method superior over the reported methods. Recovery results of 94.3 for Cd(II) and 101.0% for Pb(II) validated the applicability of the method for simultaneous determination of the two metals in a complex matrix discharged textile effluent sample. While levels of Pb(II) and Cd(II) in the untreated sample were 117 and 128.3 ppm, their levels in the treated sample were 17.7 and 101.4 ppm, respectively confirming the low efficiency of the treatment plant the factory claims to have. This results demand further analysis of potential toxic metals including Pb(II) and Cd(II).
In developing countries like Ethiopia, the issue of groundwater quality has been one of the serious environmental problems. It is mainly due to rapid urbanization, industrialization and improper land use planning. Moreover, monitoring and evaluation of groundwater quality had been mainly based on traditional based approach which is costly in terms of time and resource. This study was conducted in the Northern Ethiopia, North Wollo, in Gerado River with the aim to determine and map the groundwater quality with the help of Geographic information Sciences and physicochemical analysis. Representative sites were identified during the field investigation period. The physical parameters were done in the field whereas the physical chemical analysis for the major cations and anions, pH, hardness, turbidity, EC, and TDS were done in laboratory. The quality of water generally is defined in terms of its physical, chemical parameters and measured as water quality index (WQI). Finally the geo-statistics interpolation was used to create surface map of each variable. The WHO (1993), EMWR (2002) and Todd (1980) were used as reference guideline to determine whether the catchment’s groundwater is used for drinking and irrigation purposes or not. The result of biophysical and chemical analysis showed that the pH, hardness, turbidity, EC, TDS and major cations and anions analysis comply with the WHO (1983) and EMWR (2002) standard guidelines. Hence, it can be used for drinking purposes. The irrigation suitability of groundwater of the area was also evaluated considering SAR, %Na and EC variables using Todd (1980) standard. Accordingly, the area can be used for irrigation activities as the parameters values meet the adopted standard. Finally, the area’s groundwater spatial suitability for irrigation and drinking was developed using geo-statistics method, kriging interpolation to the create surface map.\n\nKeywords: 6
This could also be in the form of snow or heavy rainfall. It affects the economic situation of the environment, changes in land use which also affects the ecosystem. Consequently, this to a large extent affects the pavement condition of the road and leads to both structural and functional pavement defects. In a bid to proffer solution to the negative effects of storm water and reduce the cost of pavement construction in track with sustainability, this research utilized Nano clay in the development of a permeable concrete. The Nano clay was used as a partial replacement for cement. The Nano clay was dehydroxylated at 7200C, the characterization and particleometry was done using the XRF equipment. This de-hydroxylated Nano clay used as a partial replacement for cement at 5, 10, 15, 20 and 25%. Correspondingly, six samples of concrete were developed. The mechanical properties (compressive and flexural strength) were assessed at 3, 7, 14, 21 and 28 days. Additionally, the porosity of the concrete was determined using Archimedes principle. The result of the research showed that using Nano clay at 15% gave a flexural strength of 4.01MPa which is lower than the required specification of 4.27Mpa - 4.5MPa for pavement construction at 28 days and 4.5Mpa and above for airfield pavement. The porosity test using Archimedes principle showed an improved result at maturity. The result revealed that the porosity increased at maturity. This proves the efficiency of the concrete for storm water control. Therefore, this concrete is recommended for use in the design and construction of low axle or low trafficked road.
