This project focused on develops and modify a remotely operated Quadcopter system with a first person view camera. These Quadcopter is controlled through a 2.5 GHz remote control system. Communication between remote controller and Quadcopter is done by using wireless communication system. The balancing system of the Quadcopter is controlled by a gyro sensor attached with the main board. For a damage less landing and a smooth takeoff the quadcopter has a 12 cm long landing gears. The camera has been attached under the quadcopter for a better view and it uses Wi-Fi communication method to stream the video to the laptop. The main also contains a GPS module and a light sensor which can help to locate the quadcopter in case of any lost and the light sensor is attached if the quadcopter enter dark zone so the pilot can spot the quadcopter with the automatic light. Output from Arduino Uno board used to control quadcopter propellers the sensors and the communication. The output sensor data is been monitored by a GUI (Android application) and the communication between the sensors and the application made using Bluetooth module.
Consumption of unpasteurized cow milk is can be a source of infection in human. Reports shown the presence of T. gondiiin milk of lactating mammals such as sheep and camel. Grazing animals may come into contact with T. gondii oocyst in the grass passed by stray cats and later passed to the infant through lactating. Thus the aim of this study is to study the presence of T.gondii DNA in cow’s fresh milk. 15ml of milk was collected and stored at -40°C. 300µL of milk was used for DNA extraction using Genomic Mini DNA Kit. PCR was done using primer 5’-AAGCTTATGCGAGGCGGGACG-3’ and 5’-GATATCTCACTGCTTAATTTT CTCACACGTCACGG-3’. The reaction consisted of 31 cycles with the following conditions: 30 second at 98°C (denaturation), followed by 31 cycles at 98°C for 30 second (denaturation), 5 second at 64°C (annealing), and 30 second at 72°C (extension), final extension step of 10 minutes at 72°C and stopped at 16°C. Electrophoresis was done on 1% agarose gel stained with ethidium bromide (2µl). Mice peritoneal fluid infected with T.gondiiwas used as the positive control. The expected PCR product size (MIC3 gene form T.gondii) was 1080 base pairs. Results from the gel electrophoresis showed no band was formed for the milk samples. The fresh milk from Klang, UPM and Shah Alam were free from T. gondiihowever further studies should be conducted to detect other microorganisms that may be present in the milk to assure safe consumption.
A large number of micro-organisms colonize in human body. These resident microbes gives protection to the healthy human body, but at the same time when the immune system of an individual is weakened these microbes can become pathogenic and can cause infection. These microbes are adapting to the human environment very fast and using various mechanisms for survival and pathogenicity. Recently several cases has been reported of multi drug resistant Staphylococcus aureus especially in hospital settings. In this connection, present paper discusses the assessment of antimicrobial activity of isolated methicillin resistant Staphylococcus aureus strain (MRSA-MSU-101) and confirms the tetracyclin sensitivity against the isolated strain. Initially, isolation of Staphylococcus aureus strains from skin of various community people has been carried out, then the screening has been done for the methicillin resistant Staphylococcus aureus strain. One strain shown methicillin resistance labelled as MRSA-MSU-101 and considered as potentially pathogenic. Subsequently, for this strain tetracyclin efficiency assessed by antibiotic disc diffusion test (Kirby-Bauer method). This strain MRSA-MSU-101 has shown significant susceptibility against tetracyclin (1cm-diameter, zone of inhibition). Therefore, tetracyclin antibiotic is recommended for treatment against methicillin resistant Staphylococcus aureus strains.
Introduction: Gait pattern analysis is a scientific procedure used for describing the human walking pattern and examining it for characteristic idiosyncrasies.The identification of perpetrators by means of Closed-circuit Television (CCTV) is commonly used.But footprint based gait patterns are generally found at crime scenes like burglary, murder, rape etc. This study was aimed to study the footprint based gait analysis among Malaysian Indians.
Method: The study subjects consist of 100 Malaysian Indians (50 males, 50 females) and gait patterns were collected by using footprint ink, roller and footprint plate following the standard procedure for analysis.
Result: The result of this study shows that gender can be determined from footprint based gait pattern analysis. The study also proved that no two gait patterns are similar, like fingerprints.
Conclusion: Footprint based gait pattern analysis is a promising method for inclusion and exclusion of suspects and finally for person identification and the findings can be very well applied in real scene of crime in forensic perspective.
The skin can be vulnerable to various microbial infection. Although antibiotics are clinically proven to be useful in the treatment of bacterial skin infections, they are largely subjected to antibiotic resistance and adverse effects. This has led to the screening of several medicinal plants for their potential antimicrobial activity since they are less expensive, has reduced occurrence of adverse effects and widespread availability. The aim of this research will focus on evaluating the antibacterial activity of different extracts of Ipomoea aquatica leaves against Staphylococcus aureus and Streptococcus pyogenes that causes skin infections. Leaves were extracted separately with 95% methanol and 95% ethanol using maceration process. Phytochemical screening was done for each extract and the minimum inhibitory concentration (MIC) was determined for each extract against both bacteria using 10 different concentrations ranging from 10mg/ml up to 100mg/ml via disc diffusion method in triplicates. Two concentrations above the MIC from each extract were selected and antibacterial assay of the different extracts against the two bacteria respectively was performed using disc diffusion method in triplicates. MIC for methanolic extract against both bacteria was 10mg/ml, while MIC for ethanolic extract was 10mg/ml against Staphylococcus aureus and 30mg/ml against Streptococcus pyogenes. Methanolic extract of the plant at a concentration of 90mg/ml and 100mg/ml was statistically significant against Streptococcus pyogenes with a significance value of 0.00 (p
The elimination of local currencies by the creation of European Monetary Union manifested the fall of an important barrier against financial integration. Nonetheless, 2010 Eurozone sovereign-debt crisis, considered as a paradigm shifting event, led some to believe that it triggered a reversal of the integration process. Even though co-integration of equity markets among the Euro Zone countries have attracted the attention of numerous studies, the researches examining the same topic but relying on Shariah indices and specifically focusing on the effect of 2010 Eurozone sovereign debt crisis are not many. The study collects data for five stock markets’ Shariah indices, namely Germany, Belgium, Denmark, France and Italy starting from 6th September 2010 to 7th June 2013. Employing time series econometrics (known as eight steps), the study derives results suggesting that there is a strong long-run (theoretical) relationship, i.e. cointegration, among Euro Zone stock markets even after the crisis, which is believed due partly to the fact that the indices chosen are Shariah-compliant that have unique common characteristics compared to their conventional peers. As policy implications of the empirical results, it is not possible to make permanently high profits from the portfolios that are diversified only within Euro Zone markets and approximately four-decade of effort exerted by the European political institutions to create one common market is yielding optimistic results.
Oxidative stress and bacterial pathogens are two main health issues currently. This research was aims to investigate the antioxidant and antibacterial activities of leaf and branch extracts from mulberry plant. The methanolic (80% v/v) extracts of mulberry leaf and branch were examined for their antioxidant properties by DPPH radical scavenging assay. Antibacterial activity of the extracts against Staphylococcus aureus and Escherichia coli was examined using disc diffusion method, broth microdilution method and Checkerboard assay. Mulberry branch extracts showed higher antioxidant activity compared to leaf extracts, with its IC50 value was 0.443 mg/mL and 0.559 mg/mL respectively. Mulberry leaf extracts demonstrated a larger inhibition zone against Staphylococcus aureus (12.83 ± 1.26 mm) compared to the branch extract and the combination of leaf and branch extract. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of both plant materials was less than 0.79 mg/mL for Staphylococcus aureus, and 50 mg/mL for Escherichia coli. The combination of both plant materials produced an indifferent effect against Staphylococcus aureus (∑FIC = 2.0) and Escherichia coli (∑FIC = 4.0). In conclusion, the findings showed that methanolic extracts of mulberry leaf and branch contain antioxidant and antibacterial properties that have potential for pharmaceutical and nutraceutical industry.
Providing quality food and beverage services has become one of the critical issues in the tourism industry and several studies have been paying attention to it. On the other hand, there seems to be a paucity of data on service quality Jordanian hotels, making it difficult to fashion an appropriate management intervention. Also, there has been insufficient attempt to relate customers’ perceptions of service quality to their socio-demographic characteristics as well as the characteristics of organizations delivering the service. This study, therefore, analyzes customers' perceptions of service quality in the food and beverage service department in Jordanian hotels, an essential requirement for customers in Jordan.
