Published: June 2020

Dirofilariasis is a parasitic disease, caused with Dirofilaria immitis and Dirofilaria repens. Dirofilariasis can appear as a heart form and as a cutaneus form. For the spreading of dirofilariasis, the presence of mosquitoes is nessessary, because they serve as vectors Also a part of dirofilaria life cycle is developed with in the vector. Dirofilariasis can be found in dogs and cats and sometimes in humans. Even though dirofilariasis was primeraly known as a disease found in mediteranian countries, through the years it has spread out to the north and west of Europe, so now clinical cases of dirofilariasis can be found in middle Europe, including Srbija. First data on dirofilariasis in Serbia were published in 1999. and since that time there is a follow up on dirofilariasis in several regions of Serbia. During a six year period (2004. to 2010.) a study on dirofilariasis in millitary dogs within the army of Serbia was done. A few cases of adult dirofilaria were found in dogs hearts at autopsy. The study was done on 71 serum samples, from dogs of diferent age, during the study period and a total seroprevelance of 14% was found.

Advancement in biotechnology and bioengineering has provided ways that resources, which hitherto were classified as wastes, now form the basis for energy production. Anaerobic digestion is a highly promising technology used for processing biomass materials (crop residue, human excreta, animal waste and food) in the absence of oxygen to a methane-rich biogas. This work developed a small-scale anaerobic digester to produce biogas from animal waste. The anaerobic digester consisted of three major components: bioreactor with an incorporated stirrer driven by an electric motor, gas scrubber and gas collector. Batch feeding operation was adopted while pig waste was used as test material. Lime water was used as a scrubbing medium for methane enrichment. Loading result revealed that there was seven days delay in gas production from day of loading. The daily temperatures and pH recorded for a period of 50 days were in the range of 29 - 34°C and 5.5 - 7.5 respectively, and the average yield of clean biogas was 0.13 l/kg of slurry/day. Biogas generation increased with days in digester and was a two-stage process with a peak production day between 40 and 45 days. There was observed reduction in carbon dioxide content and methane enrichment as the days increased confirming the effectiveness of the scrubber. The biogas produced comprised between 55.1 and 74.1% of methane, and a range of 22.5 to 38.2% of carbon dioxide and was combustible after the 10th day of digestion. The results obtained showed the overall functionability of the developed anaerobic digester. The digester could be deployed and adopted in farmsteads as well as household to meet their energy demand

Published: June 2020

Corrosion inhibition potential of Eichhornia crassipes extract on low carbon steel in 1 M sulphuric acid solution was investigated using gravimetric method and corrosion rate. The experiment was carried out for 3 hours at different concentration of Eichhornia crassipes extract and temperatures of 26.6°C, 40°C and 60°C. Arrhenius and improved Arrhenius equations were used to determine the thermodynamics properties of the reaction while the nature of the reaction was proposed by adsorption isotherms. The results showed that corrosion rate decreased in the presence of the extract except in 60oC. Inhibition efficiency also increased with extract concentration with the highest (82%) occurring at room temperature and 5% concentration. Inhibition efficiency decreased with increase in temperature with almost no inhibition at 60oC, this is associated with physisorption. Activation energy () and activation enthalpy () both had positive values and they increased in the presence of Eichhornia crassipes extract, those for inhibited solution were higher than those for uninhibited solution, these can also be attributed to physisorption. Inhibition reaction obeyed Langmuir adsorption isotherm. Gibbs free energy () calculated for the reaction is -8.509 to -11.767 kJ mol-1.

Hypertensive-patient monitoring is a continuous process of observing closely the situation of patient's blood pressure and alerting the appropriate personnel in case of any anomaly. It usually requires the use of non-invasive sensors that are hardwired to bedside monitors. Although, present systems allow continuous monitoring of patient vital signs and limit the patient to the bed, the readings are mostly stored on the system local memory over a period of time before it is assessed for analysis. Hence, the need for a real time hypertensive patients’ monitoring system which can meet up with immediate demands of emergency cases. This paper presents a Wireless Sensor Network (WSN)-based health monitoring system that addressed the aforementioned drawbacks for monitoring hypertensive in-patients. The design of the system comprises of hardware components such as blood pressure sensor, Bluetooth serial communication circuit, sensor node for base station interfaces and software components. Performance evaluation of the designed system gave an accuracy of 89.7% in blood pressure monitoring. The system is also cost effective, reliable and user friendly when compared with existing systems. Keywords— Blood Pressure, Health monitoring, Hypertension, Wireless Sensor Networks

Published: June 2020

Outage and complimentary load flow analyses of a selected 33kV primary distribution network in Ughelli Delta State, Nigeria, were carried out to depict feeder availability obtainable in the country. Outage and load flow analyses were carried out using parametric statistics and Newton-Raphson computation algorithm respectively. The results provide model distribution of monthly feeder availability, contributions of outage factors and normal load flow values. It was concluded that: monthly feeder availability represented using normal probability distribution function of; shows that overcurrent and earth faults contribute to outage duration, taking 5% to 12% of the month outage duration respectively; coupled with significant line losses and weak voltage profile. Recommendations proposed include: replacement of weak or failed elements and insulations in the systems with new and modern ones to mitigate especially earth faults in the short term; planning for immediate increase in system capacity to accommodate the power demand effectively for present and forecast periods to eliminate load shedding, overload events, and high technical losses; maintenance practice at the planning and execution stages to mitigate failure events and repair time.

Published: June 2020

Pavement rehabilitation where the material in the existing pavement is recycled in-situ with bitumen will sustain the environment with conservation of natural aggregates, reduction in noise, dust emission and traffic disruption. This study investigate the effects of a native South African granular material stabilized with cement and bitumen emulsion as a base layer in pavement construction. The material stabilized with cement-bitumen emulsion (2-3%) was subjected to Unconfined Compressive Strength (UCS) and Indirect Tensile Strength (ITS) tests for 1, 4, 7 and 28 days curing. The UCS and ITS requirement was evaluated with respect to a base layer for design traffic application of less than six million equivalent single axles. The results of UCS and ITS tests for the stabilized material showed improved strength and have the potential for use as a base course material for the design traffic. The result revealed that 2.5% cement and bitumen emulsion meets the minimum strength characteristics for the base layer. Relative to 2% cement and 2% bitumen emulsion, ITS obtained for 4 and 7 days of curing increased approximately by 24%, 41% and 24%, 53% respectively. Models for UCS in terms of ITS was developed for cement and bitumen emulsion which will make one test among the two sufficient to indicate the strength of cement and bitumen emulsion stabilized materials at the mix design level. Bitumen stabilization is a quick construction method, with lower cost than reconstruction and good for rehabilitation. Keywords— bitumen emulsion, cement, granular, indirect tensile strength unconfined compressive strength.

Authors: Dandajeh Hamisu A , Ahmadu Talib O 
Published: June 2020

This paper presents an experimental investigation on the influence of engine speed on the combustion characteristics of a Gardener compression ignition engine fueled with rapeseed methyl esther (RME). The engine has a maximum power of 14.4 kW and maximum speed of 1500 rpm. The experiment was carried out at speeds of 750 and 1250 rpm under loads of 4, 8, 12, 16 and 18 kg. Variations of cylinder pressure with crank angle degrees and cylinder volume have been examined. It was found that RME demonstrated short ignition delay primarily due to its high cetane number and leaner fuel properties (equivalence ratio (φ) = 0.22 at 4kg). An increase in thermal efficiency but decrease in volumetric efficiency was recorded due to increased brake loads. Variations in fuel mass flow rate, air mass flow rate, exhaust gas temperatures and equivalence ratio with respect to brake mean effective pressure at engine speeds of 750 and 1250 rpm were also demonstrated in this paper. Higher engine speed of 1250 rpm resulted in higher fuel and air mass flow rates, exhaust temperature, brake power and equivalent ratio but lower volumetric efficiency. Keywords— combustion characteristics, engine performance, engine speed, rapeseed methyl Esther

Published: June 2020

The potential occurrence of certain illnesses can be easily diagnosed through measurements of some health indicators. One of such parameters is the Body Mass Index (BMI). BMI is simply the ratio of mass (kg) of a body to the square of its height (m2). This research presents the design and construction of an automated BMI measurement machine for medical purposes. It consists of three major units: the weighing unit (5 – 200 kg); height-measuring unit (0.02 – 2 m) and the processing unit. The weighing unit is made up of load button cell and load cell amplifier while the height-measuring unit consists of ultrasonic sensor. The analog differential output voltage from load cell is connected to arduino microcontroller via a Programmable Gain Amplifier (PGA) integrated with Analogue-to-Digital Converter (ADC). The two units are connected to an open source arduino uno which computes mass-to-body ratio and sends the output results (mass, height and BMI) to the liquid crystal display (LCD). The weighing system was calibrated against a precision digital weighing system and it gave a correlation of 0.99. The height measurement was also compared with manual height measurement using a tape rule which gave a correlation of 0.97. The developed Instrument is cost effective and has high positive correlation with the standards (weighing scale and tape rule), it is therefore recommended for the measurement of weight, height and BMI.

Published: June 2020

Aluminium alloys demonstrate exceptional properties such as high strength-weight ratio and corrosion resistance are used for general engineering applications, automobile, automotives and in aerospace industries. However, they suffer some limitations as wear and creep at high temperatures. With the trending developments from nanometallurgy, diverse nano-particle compounds of mono and heterogeneous compositions have been used in reinforcing aluminium and its alloys as widely reported in the public domains. This paper reviews some of the vast literature on the enhancement of nanostructured aluminium alloys and reinforced aluminium nanocomposites. Importance is laid on the tribological and mechanical behaviours of the manufactured composites and nano-composites with respect to their production methods and applications at elevated (high) and cryogenic (low) temperatures. Keywords— Tribology; mechanical behaviours; nanostructure; aluminium alloys; nano-composites; elevated temperatures
Comparative Analysis of XML Schema Languages for Improved Entropy Metric
Authors: Sotonwa Kehinde A 
Published: June 2020

The eXtensible Markup Language (XML) is a data set to represent data in a format that is both human readable and machine readable. For XML documents to provide understanding about data exchange between applications, XML schema documents should be validated against the schema language. Most existing schema metrics were implemented differently in Document Type Definition (DTD), XML Schema Definition (XSD) and Regular Language for Next Generation (RNG) but never compare XML schema languages on any metric. Hence this paper compared three different schema languages on Improved Entropy Metric (IEM) using the Number of Attributes (NA), Number of Equivalence Class (NEC), Frequency Occurrence of Class (FOCi) and Number of Elements (NE). The proposed metric was applied on real schemas documents data are acquired from Web Service Description Language (WSDL) and implemented in DTD, XSD and RNG. The result showed that RNG reduce complexity of class elements, reflect strong support for class elements to appear in any order which showed more reusability and flexibility traits and overall understanding of the schema documents becomes much easier because RNG can be algorithmically converted and partner with other schema languages therefore this reduces maintenance effort.

Published: June 2020

In this article, a new implicit continuous block method is developed using the interpolation and collocation techniques via Power series as the basis function. A constant step length within a seven-step interval of integration was adopted. The selected grid points were evaluated to get a continuous linear multistep method. The evaluation of the continuous method at the non-interpolation points produces the discrete schemes which form the block. The basic properties of the block method were investigated and found to be consistent, zero stable and hence convergent. The new method was tested on real life problems namely: SIR and Growth model. The results were found to compare favourably with the existing methods in terms of accuracy and efficiency. Keywords: Block method, Growth Model, implicit, power series and SIR model.
Arquitectura para dos carismas distintos en el Bajo Aragón turolense en el Seiscientos: el convento carmelita de Alcañiz y el descalzo del Desierto de Calanda
Authors: Martín Marco Jorge 
Published: June 2020

En el Bajo Aragón turolense se asentaron un gran número de órdenes religiosas en las primeras décadas del Seiscientos, y entre ellas, los carmelitas, que llegaron a Alcañiz en 1602; o los descalzos, que se establecieron en el convento del desierto de Calanda en la década de los ochenta de ese siglo. Sin embargo, las diferencias entre ambos establecimientos son evidentes, ya que fueron concebidos tanto espiritual como arquitectónicamente diferentes uno de otro debido a las funciones que debían cumplir. El caso alcañizano es una de las muestras más destacadas de la arquitectura bajoaragonesa del barroco, mientras que el calandino es un buen ejemplo de desierto carmelita, cuyas trazas probablemente fueron realizadas por artífices de la orden.
Abstract
A great number of religious orders settled in the Bajo Aragón in Teruel in the first decades of the 17th century, among them the Carmelites that arrived in Alcañiz in 1602; or the Discalced, that settled in the convent of the desert of Calanda in the decade of the 80s of that century. However, the differences between both establishments are evident, since they were conceived differently both spiritually and architecturally due to the different function that they had to fulfil. In the case of Alcañiz, it is one of the most prominent samples of the architecture of the Bajo Aragón in the Baroque period, while in Calanda's case, it is a good example of Carmelite desert, the design of which were probably made by authors of the order.

Authors: Amarilla-Donoso Francisco Javier , Roncero-Martin Raul , Lavado-Garcia Jesus Maria , Toribio-Felipe Rosaura , Moran-Garcia Jose Maria , Lopez-Espuela Fidel 
Published: June 2020

Background
Hip fracture is an important and frequent health problem worldwide. To date, there are still limited studies focused on the analysis of health-related quality of life (HRQOL) after a hip fracture in the Spanish population, especially with long-term follow-up.

Objective
To determine the HRQOL at 12 months after hip fracture and to identify potential factors associated with HRQOL.

Design
Prospective observational study.

Setting
Traumatology units of two university hospitals in province Cáceres (Spain).

Participants
A total of 224 patients were admitted to the unit and required immediate surgery due to a hip fracture.

Methods
HRQOL was measured with the EuroQol-5D questionnaire (EQ-5D) and the SF-12 Health Survey.

Results
Scores from the visual analog scale EQ-5D decreased significantly (p < 0.001) from 72.8 at baseline to 48.3 after 1 month, to 48.2 after 6 months and to 46.1 after 12 months. The EQ-5D index score showed a similar significant reduction (p < 0.001) from 0.6 to 0.1, 0.3 and 0.3, respectively. Values of the physical component summary (PCS-12) significantly decreased (p < 0.001) from 38.6 at baseline to 31.0, 33.1 and 33.5. The mental component summary (MCS-12) decreased from 46.5 to 44.8 after 6 months (p = 0.022) and 44.3 after 12 months (p = 0.005). Factors potentially associated with HRQOL at 12 months after hip fracture were depression status after 12 months (B = 0–1.876; 95% CI [−2.409 to −1.343]; p < 0.001), functional ambulation classification after 12 months (B = −12.133; 95% CI [−17.970 to −6.297]; p < 0.001), EQ-5D VAS at baseline (B = 0.223; 95% CI [0.115–0.330]; p < 0.001), and age (B = −0.323; 95% CI [−0.594 to −0.053; p = 0.015).

Conclusions
Patients experience a significant impairment in HRQOL H after a hip fracture, especially in self-care, pain/discomfort, usual activities, mobility and anxiety/depression. The decline in the HRQOL is effective the first month and lasts at least 12 months after the surgical intervention.
