Titania-Loaded Coal Char as Catalyst in Oxidation of Styrene with Aqueous Hydrogen Peroxide

Abstract Titania-loaded coal char catalyst was successfully prepared. The preparation steps involved pyrolysis of low rank coal at different temperatures and durations, sulfonation, impregnation of titanium(IV) isopropoxide, and then heating at 110 °C. It is found that the coal chars’ surfaces were rough after sulfonation and impregnation, while large pore volume, high surface area and carbon composition were observed at low pyrolysis temperature for short duration. These properties contributed to high selectivity towards benzaldehyde (> 90 %) at 600 °C (0.5–2 h)) in styrene oxidation using aqueous hydrogen peroxide as the oxidant.
Aseismic strain episodes at Campi Flegrei Caldera, Italy

Abstract. Since 2004 a research project has been developed to monitor subsurface deformation of Italian volcanoes using borehole strainmeters and long-baseline tiltmeters. Six Sacks-Evertson dilatometers were installed around Campi Flegrei caldera and Vesuvius during 2004–2005 (Scarpa et al., 2007), and in 2008 these instruments were supplemented by two arrays of 28–280 m long water-tube tiltmeters in underground tunnels. Relevant strainmeter and tiltmeter data have been collected and analysed from the instruments installed near Campi Flegrei caldera during the recent unrest episodes. In the period 2004–2005 strain, tilt and GPS data from Campi Flegrei indicate the onset of surface deformation that accompanied a low rate of vertical displacement that continued to 2006, corresponding to an increase of CO 2 emission. This strain episode preceded caldera microseismic activity by a few months, as was observed also during a significant inflation episode in 1982. Other transient strain episodes occurred in October 2006, which were accompanied by a swarm of VT (Volcano-Tectonic) and LP (Long Period) events, in 2009, at the time of renewed gas emission activity at Solfatara, and again in March 2010, several minutes before a seismic swarm. The time scale of these transient strain events ranges from some hours to several days, putting tight constraints on the origin of ground uplifts at Campi Flegrei. Their location is compatible with a source inferred from long term deformation signals, located about 4 km beneath Pozzuoli. A proposed mechanism for these aseismic strain episodes is that they are associated with magma growth in reservoirs with occasional pressure relief associated with the leakage of gas.
Lift Traffic Design: Calculation or Simulation?

Lift traffic design has become an integral part of tall building design. Typically, design calculations and/or simulations are iterated many times from early sketches until lifts are in use. Each iteration requires a significant effort from the parties involved in the design, namely, architects, consultants, developers and often also lift suppliers. Therefore, lift traffic design should be carried out with the most appropriate method to minimize the effort. Traffic calculation based on uppeak roundtrip is a well-known method and fast to execute but its validity is limited to collective control systems and simple building configurations. Lift traffic simulation, on the other hand, allows complex building models, traffic patterns and lift products such as destination control systems, double-deck lifts and multi-car lift systems. Simulations usually have long runtime and are susceptible to statistical inaccuracies possibly unknown to the designer. Hence, some combination of calculation and simulation is desirable to benefit from both methods, but they should provide consistent results. This paper re-establishes the link between traffic calculation and simulation with a collective control system, which sets the standard for using both methods consistently in lift traffic design with both collective and destination control systems.

Effect of environmental factors on Solar-panel Power Loss and Photovoltaic Performance

Solar energy as the most important source of renewable energy is an important alternative to fossil and non-renewable energies which is highly related to the environmental changes. The power output delivered from a photovoltaic module depends on the amount of irradiance which reaches the solar cells. Many factors determine the ideal output or optimum yield in a photovoltaic module which can be classified to climatological, cosmological and geographical conditions. These environmental factors are directly affecting the performance losses in solar cells. The presented paper attempted to use the long short-term memory (LSTM) to evaluate the environmental parameters influencing on photovoltaic cells performance losses. According to the simulations, intensity and radiation angle, shadow, temperature, wind and air pressure are the main parameters which affect the solar cells functions and loss the performance.

Relationship between Grasping Actions and Object Attributes: A Survey

Object grasping of humans and robots is a research topic that contains many challenges. This process needs to solve many problems in the field of computer vision and robotics such as kinetics, hand recognition and positioning, object recognition and positioning in the environment, generate hand shape to grasp, detect grasp area. To perform an effective grasp, it is necessary to understand the attributes of the grasp object. From this taking manipulation actions to fit with the object attributes. In order to make automatic grasp, the steps in (grasp types recognition, object attributes recognition, manipulation actions recognition) need to automatically understand and follow a consistent model. In the paper, we conduct a survey and systematized approaches to solve each component problem based on the relationship of interaction between issues: grasp types recognition, object attributes recognition, manipulation actions recognition. Approaches to solve each problem are presented from traditional methods to modern methods. For example, the training of identification models is presented based on traditional methods such as using SVM to train on characteristics to use deep learning models with the Convolutional Neural Networks (CNNs) for training identification model.
Socio-economic and Bio-physical Resources Characterization of ‘Warja’ Watershed in Adami Tulu Jido Kombolcha District, East Shewa Zone, Oromia, Ethiopia

Watershed development is an important component of rural development and natural resource management strategies in many countries. The study was conducted to investigate the current situation of Warja watershed for further improvements to promote Sustainable and productive livelihood through the integration of different watershed components in participatory approach. Household interview and biophysical resources assessment followed by watershed mapping techniques were used for the data collection. Purposive sampling methods were used to select 63 households and Warja watershed boundary was delineated and its map was developed based on the preliminary outlet identified with the help of GPS reading. Descriptive statistics and diversity indices were used for data analysis. The results of the study indicated that Agriculture was the principal occupation (98.4%) of the population of Warja watershed. The average farmland size was 1.9 hectares while 25% of the households have farmland ranging from 0.25 to 1 hectare. The minimum and maximum family size of the sample farm households was 2 and 16 respectively. The common types of off-farm income generating activities are petty trade and working as daily labor. Slope gradient of Warja watershed ranges from 0 to more than 30 and the slope gradient of 2-5 and 5-10 cover the greatest in area coverage representing 204ha and 145ha respectively. Soil laboratory analysis result showed that sandy loam was the major soil type of Warja watershed.

Awareness creation and strengthening capacity of rural communities on integrating crops, livestock and natural resource management technologies for effective soil and water conservation measure should be enhanced through participatory integrated watershed management approach.
Castleman Disease in Children from Histopathology to Therapy

Background: Castleman disease (CD) describes a group of rare lymphoproliferative disorder with characteristic histopathology. It presents with heterogeneous clinical features whether unicentric (UC) or multicentric disease (MCD). The aim of the work was to describe clinic-pathological characteristics, management and outcome of different types of castleman disease in CCHE. It is a retrospective study, all children with (CD) treated from July 2007 till end of 2017 were analyzed as regard diagnosis, management and outcome. The results showed that, twelve patients with a median age of 11.5 years (ranging from 4 - to 17 years) were enrolled. Eight of them (66.6%) were males and 4 (33.3%) were females (33.3%). Histopathology was either hyaline vascular in 8 patients (66.6%) or plasma cell variant in 4 patients (33.3%). Nine patients (75%) had uni-centric disease (UC) with lymphadenopathy. Three patients (25%) were multi-centric disease (MCD); out of them one patient had immune bi-cytopenia, small intestinal thickening and splenomegaly and another one had extensive pulmonary involvement and respiratory distress, while the third patient had pleural effusion and ascites. HIV antibody was negative for all patients. Regarding the three MCD patients, IL-6 was normal in one patient, and extremely high in second one, while it hasn’t been done for the third patient. All UC patients underwent surgical excision and are alive with no active disease till now. All MCD patients received systemic steroids as initial therapy, followed by R- CHOP (Rituximab-cyclophosphamide-doxorubicin-vincristine-prednisone) as salvage therapy, except for one patient with pulmonary involvement who didn’t achieved clinical response and received single agent Rituximab with Anti IL-6. Unfortunately this patient is still having uncontrolled systemic manifestation, while the other two patients showed partial response. In conclusion, Uni-centric castleman disease is a localized surgically cured disease. MCD treatment remains challenging, and the outcome is controversial, so Uniform treatment guidelines are mandatory.

Modified solid ion-selective electrode for potentiometric determination of sulfide in oil refineries water

A scientist, developed electrode membranes at the beginning of the twentieth century with the discovery of the glass electrode, which is one of the important tools in laboratories, as it response to hydrogen ions (Skoog, Holler & Nieman, 1998). Among the different analytical techniques (Mahajan, Kaur, Sharma & Kumar, 2002) and as a result of the development of research, advances in this area began in the 1960s, when Rokosing and Pungor developed a new type of solid sensor (Cattral, 1997). The field of ion-selective electrodes has experienced rapid growth since the past two decades (Arida, Ahmed & El-Saied, 2003), and chemical sensors are miniature analytical devices that can provide information about the presence of specific compounds or ions in complex samples (Wroblewski, 2009), which are dependent on the development of static electricity potential difference across a membrane. It separates two phases. When placed in a solution containing ions (Cattral, 1997), it is one of the most importantly fast and simple modern electrolysis techniques that require the current passing through them to be equal to zero (Othmer, 1981). The use of ion-selective membrane electrodes is a good analytical technique. Due to its several advantages over conventional analysis methods for example they provide accurate, repeatable, fast, and often selective identification of different ions (Liu, Zhao, Chen & Che, 2000). Sulfide is an anion that is widely present in both natural, wastewater, and industrial waters, and it is one of the most important factors to monitor in water due to its high toxicity to aquatic organisms. The sulfide toxicity is attributed to the release of hydrogen sulfide (H2S) (Huang et al., 2010) and hydrogen sulfide (H2S) is one of the most dangerous highly corScientific Review – Engineering and Environmental Sciences (2021), 30 (1), 98–105 Sci.

Evaluation of soil physical quality in dominant series of calcareous soils in south-west of Iran

Calcareous soils are widely spread in arid and semiarid regions. Carbonates can affect soil quality by influencing soil pH, structure and soil available water. There are lots of calcareous soils in Iran and especially Khuzestan province, so, providing sustainable agriculture evaluating the soil quality is essential. This study was done to evaluate the soil physical quality in dominant calcareous soil series in Khuzestan province, Iran. Soil physical quality indicators, including Dexter's S index, air capacity, soil available water capacity, relative water capacity and macroporosity were calculated. The results showed that, based on Dexter's S index, only one calcareous soil series had a poor physical quality (S < 0.035). However, the simultaneous evaluation of different soil quality indicators showed that 56 % and 22 % of studied calcareous soil series had limited aeration and soil available water, respectively. While the weakest soil physical quality was related to the southeastern soil of Ahvaz, with both aeration and soil available water limitations. The results showed that the proper assessment of soil physical quality in calcareous soils requires considering more physical indicators than just Dexter's S index related to soil aeration condition including air capacity and macroporosity.
Activity versus Selectivity of the Methanol Oxidation at Ceria Surfaces: A Comparative First-Principles Study

Ceria nanoparticles may expose (100) and (111) facets depending on the preparation method. Motivated by that, we study the reactions of methanol with the CeO2(100) surface using dispersion-corrected PBE+U subject to periodic boundary conditions and compare with results for the CeO2(111) surface. At (100) facets, the oxidative dehydrogenation of methanol to formaldehyde occurs with an intrinsic barrier of only 0.94 eV (91 kJ/mol), which is significantly lower than the corresponding barrier of 1.23 eV (119 kJ/mol) at the (111) surface. The lower barrier maps to lower formaldehyde desorption temperatures as observed in temperature-programmed desorption spectroscopy. The higher activity is in accordance with predicted lower oxygen defect formation energy in the (100) surface. Thus, defect formation energies are valid reactivity descriptors for oxidation reactions following a Mars-van Krevelen mechanism. At both surfaces, formaldehyde either desorbs or forms a bridging dioxymethylene intermediate, which can be.
APPLICATION OF CMSY TO ESTIMATE BIOLOGICAL REFERENCE POINTS OF BOMBAY DUCK (Harpadon neherus) FROM THE BAY OF BENGAL, BANGLADESH

CMSY method was used to calculate Biological Reference Points (BRPs) of Harpadon nehereus using seventeen years (2001-2017) of catch data from the Bay of Bengal (BOB), Bangladesh. CMSY requires only catch and resilience data with quantitative stock status information. Also, a Bayesian statespace implementation of the Schaefer production Model (BSM) was used. The lowest Maximum Sustainable Yield (MSY) was provided by BSM (60600 t) that was smaller than last year's catch (82767 t in 2017). The fishing mortality (F) was estimated to be 0.22 and 0.23 for CMSY and BSM, respectively. The intrinsic population growth rate (r) was lower according to BSM (0.37) than the CMSY (0.57). Calculated B/BMSY was 1.13 and F/FMSY was 1.21 from the BSM model for the last data year. Estimated BRPs directed the overfishing status that may lead the H. nehereus fishery to be unsustainable. Therefore, proper management strategies are required to ensure the sustainability of H. nehereus in the BOB, Bangladesh.

Emotional and behavioural problems among adolescents attending selected schools of Rohtak, Haryana: A cross-sectional study

Background: Adolescence is the period marked by an enormous transition of physiological and psychological characteristics. Most psychological problems begin during childhood and adolescence have consequences for later life. Aim: The study assessed the patterns of emotional and behavioural problems (EBPs) among adolescents attending selected schools of Rohtak District, Haryana. Methods: A cross-sectional study was conducted in five schools in Rohtak district, Haryana. Strength and Difficulty Questionnaire (SDQ) was used for the assessment of EBPs and 400 adolescents were recruited through convenience sampling. Results: About 53% of the subjects were boys and the mean total difficulty score of SDQ was 10.14 (SD of 5.22). The overall prevalence of EBPs was 5.5 % (03.66 08.19 %; 95% CI) as per the total difficulty score of SDQ. Conduct problems (8.8%; 06.36 11.93; 95% CI) were the most prevalent EBPs among all the subscales of SDQ in this setting. Conclusion: About one-fifth of the school-going adolescents reported to have EBPs in this setting. The regular incorporation of mental health services can be an effective strategy to bolster adolescent resilience in the school setting.
