AN ANALYSIS OF SOLAR POWERED UNMANNED AERIAL VEHICLE

Unmanned Aerial Vehicles (UAVs) or otherwise known as Drones define that on-board pilot is replaced by a remote controlled computer system and the radio link. The increasing presence of drone technology and its influence in today’s world is quite apparent. UAVs have immeasurable potential in different services where they are becoming eyes and ears and providing a broad range of solutions. Flying opens new opportunities to soar above the horizon and snap a photo or videoand we experience the benefits that they are providing. However, despite the promising potential, one of the main problem is endurance or flight time as it uses limited energy storage batteries or conventional fuel which has a limited life and is costly. Using solar energy through solar cells into modern aircraft technology instead of increasing the size of the fuel system or battery sizing will increasing the potential of unmanned aerial vehicle. The aim of this paper is to gives an overview of solar-powered drones and their design for a 36-hrs endurance flight.
Nutritional Components and Oxidative Stability of Plant Seed Oils

This study investigated fatty acid compositions, antioxidative nutrients, physicochemical properties, and oxidative stability of 10 plant seed oils derived from forest resources. Eight types of fatty acids were identified in total, of which oleic acid marked the highest proportion in most of the seed oils. Overall, the seed oils showed relatively higher contents of unsaturated fatty acids (≧50%). Tocopherol and phytosterol contents ranged from 4.82±0.11 mg/ 100 g to 738.35±4.30 mg/ 100 g and from 133.44±5.09 mg/100 g to 403.59±29.89 mg/100 g, respectively. In terms of chemical measures, acid value, peroxide value, and p-anisidine value resulted in broad ranges, between 0.81±0.04 mg KOH/ g and 52.3±0.60 mg KOH/ g, 4.95±0.11 meq/ kg and 213.88±6.97 meq/ kg, and 3.53±0.39 and 62.59±1.67, respectively. Browning intensity and color scale were also examined, which probably will be a good indicator of sensory quality. As a measure of oxidative stability, oxidation induction period was investigated, showing a range of 0.02±0.01 hr to 3.72±0.28 hr. This study provided informative fundamental data on forest resource derived- 10 plant seed oils and demonstrated the possibility of these oils as edible oil sources with favorable nutrient and physicochemical features.
Efficient Estimation of Biomass from Residual Agroforestry

Cost-effective sampling methods for the estimation of variables of interest that are time-consuming are a major concern. Ranked set sampling (RSS) is a sampling method that assumes that a set of sampling units drawn from the population can be ranked by other means without the actual measurement of the variable of interest. We used data on vegetation dynamics from satellite remote sensing as a means in which to rapidly rank sampling units across various land covers and to estimate their residual agroforestry biomass contribution for a small cogeneration facility located in the center of a study area in central Italy. A remote sensing map used as an auxiliary variable in RSS enabled us to cut down the photo-interpretation of the residual biomass present in sampling units from 745 to 139, increase the relative precision of the estimate over common simple random sampling, and avoid individual subjective bias being introduced. The photo-interpretation of the sampling units resulted in a 1.12 Mg ha−1 year−1 mean annual density of residual biomass supply, although unevenly distributed among land cover classes; this led to an estimate of a yearly supply of 132 Gg over the whole 2276 km2 wide study area. Further applications of this study might include the spatial quantification of biomass supply-related ecosystem services.
Use of Lactobacillus fermentum for improving fermentation degree of smallholder dried cocoa beans

Cocoa beans produced from smallholder farming in Indonesia, are renowned for their low quality as a consequence of omitting fermentation. The unfermented beans are characterized with higher number of slaty and full purple cotyledons besides lower quality of chocolate aroma and flavor. Lactobacillus fermentum (LF) is one of the naturally available microorganisms in cocoa fermentation. LF culture had been reportedly successful in enhancing fermentation of fresh cocoa beans, however its effects on dried unfermented beans has not been investigated. This study aimed to evaluate the ability of LF culture in improving fermentation degree and sensory quality of dried unfermented beans. LF culture at concentration 5% w/w was added into dried cocoa beans under moist condition and incubated for four days. Treated beans were sun dried and evaluated for slaty and purple appearance on the nibs, as well as defects and sensory quality. This study reports a significant decrease in the proportion of slaty and purple beans in the treated groups either in smaller (30 kg) or in the larger (150 kg) scales. The mouldy bean number surged, compared to in the untreated one. Its sensory profile obtained higher scores on the quality chocolate flavor which was due to stronger intensity. The quality of bitterness and astringency were also improved, due to lower intensity. It is concluded that LF culture could be used for improving the physical and sensory qualities of cocoa beans from smallholder farmers.
Relationship between Urinary Liver-Type Fatty Acid-Binding Protein (L-FABP) and Sarcopenia in Spontaneously Diabetic Torii Fatty Rats

Background Type 2 diabetes (T2D) is a known risk factor for diabetic kidney disease (DKD) and sarcopenia in older patients. Because there may be an interaction between DKD and sarcopenia, the aim of the present study is to investigate the relationship between urinary levels of liver-type fatty acid-binding protein (L-FABP) and sarcopenia using a novel rat model of T2D. Methods Male spontaneously diabetic Torii (SDT) fatty rats (n = 5) at 16 weeks of age were used as an animal model of T2D. Age- and sex-matched Sprague-Dawley (SD) rats (n = 7) were used as controls. Urine samples were obtained from the rats, and muscle strength was evaluated with the use of the forelimb grip test at 16, 20, and 24 weeks of age. Serum, kidney, soleus, and extensor digitorum longus (EDL) muscle samples were collected at 24 weeks of age. Urinary L-FABP levels were measured using dedicated enzyme-linked immunosorbent assays. Results Increased urinary L-FABP levels, focal glomerular sclerosis, moderate interstitial inflammation and fibrosis, and accumulation of renal oxidative proteins were significantly observed in the SDT fatty rats, compared to the SD rats. Muscle weight, muscle strength, cross-sectional areas of both type I and type IIb muscle fibers, and increasing rate of muscle strength were significantly decreased in the SDT fatty rats compared to the SD rats at 24 weeks. Urinary L-FABP levels at 20 and 24 weeks were significantly negatively correlated with muscle strength. Urinary L-FABP levels at 16 weeks were significantly negatively correlated with the increasing rate of muscle strength. Conclusions Urinary L-FABP reflects the degree of muscle strength and weight, as well as cross-sectional areas of muscle fibers. Although further clinical study is needed, urinary L-FABP may be useful to monitor the progression of sarcopenia and DKD in T2D patients.
Mental Health Detection from Speech Signal: A Convolution Neural Networks Approach

Mental health disorder is a global topic, the current situation is particularly serious in China. The objective and automated detecting of mental health using speech signal has become popular. In the absence of depressed speech corpus, the authors regard depression as a negative emotion, and build the model by Convolution Neural Networks (CNNs), a machine learning method for detecting mental health disorder interchanging with emotional speech. In this experiment, the segmented speech was represented as a spectrogram in the frequency-time domain via a Short-Time Fourier Transform (STFT), and these images were as input of the CNNs model. It highlights some advantages that CNNs can offer mental health detection. Results indicate that it is a good attempt and this method can be directly utilized by interchanging with emotional speech.

Implications required to increase numbers and expenditures of domestic tourists were suggested.
Waldo: Batteryless Occupancy Monitoring with Reflected Ambient Light

Reliable and accurate room-level occupancy-tracking systems can enable many new advances in sensors and applications of modern smart buildings. This allows buildings to be more capable of adapting to the needs of their occupants in their day-to-day activities and better optimize certain resources, such as power and air conditioning, to do so. Unfortunately, existing occupancy-tracking systems are plagued by large size, high energy consumption, and, unsurprisingly, short battery lifetimes. In this paper, we present Waldo, a batteryless, room-level occupancy monitoring sensor that harvests energy from indoor ambient light reflections, and uses changes in these reflections to detect when people enter and exit a room. Waldo is mountable at the top of a doorframe, allowing for detection of a person and the direction they are traveling at the entry and exit point of a room. We evaluated the Waldo sensor in an office-style setting under mixed lighting conditions (natural and artificial) on both sides of the doorway with subjects exhibiting varying physical characteristics such as height, hair color, gait, and clothing. 651 number of controlled experiments were ran on 6 doorways with 12 individuals and achieved a total detection accuracy of 97.38%. Further, it judged the direction of movement correctly with an accuracy of 95.42%. This paper also evaluates and discusses various practical factors that can impact the performance of the current system in actual deployments. This work demonstrates that ambient light reflections provide both a promising low-cost, long-term sustainable option for monitoring how people use buildings and an exciting new research direction for batteryless computing.
Biodegradation Potentials of Aspergillus sydowii and Fusarium lichenicola on Total Petroleum Hydrocarbon in an Oilfield Wastewater in Rivers State

This study investigated the potential of Aspergillus sydowii and Fusarium lichenicola as mixed cultures in the biodegradation of Total Petroleum Hydrocarbons TPHs in oilfield wastewater. Oilfield wastewater was collected from an onshore oil producing platform and biodegradation of total petroleum hydrocarbons was investigated using standard methods. Fungi were isolated from oilfield wastewater contaminated soils obtained from the vicinity of the oil producing platform. Experimental control set-up and treatment with mixed culture of fungal isolates were periodically analyzed on days 7 and 21 intervals for total petroleum hydrocarbon degradation using Gas Chromatography (GC). The total amount of TPHs on day 1 recorded 381. 871 mg/l. The amount of TPHs on days 7 and 21 in the mixed culture of fungi was 108.975 mg/l and 21.105 mg/l respectively while TPHs in control was 342.891 mg/l and 240.749 mg/l respectively. There was a significant difference between the mixed culture and the control on days 7 and 21 at p≤0.05. The results therefore revealed actual and Original Research Article Williams and Aleruchi; JAMB, 19(3): 1-7, 2019; Article no.JAMB. 53096 2 significant reduction of TPHs in the mixed culture. In addition, there was clearance of n-alkanes by the mixed culture. This suggests that fungi have great potentials in biodegradation of TPHs and in remediation of TPH contaminated environments.
COUNTERACTING FINANCIAL EXCLUSION AS AN ETHICAL ASPECT OF THE ACTIVITIES OF COOPERATIVE BANKS BASED ON OWN RESEARCH

The main purpose of this thesis is to present the opinions of clients on the ethical aspects of the activities of cooperative banks in the context of limiting financial exclusion. The author attempts to answer the questions: were clients refused with banking services, what were the reasons for this refusal, do cooperative banks offer electronic banking services to limit financial exclusion. The empirical basis of the issues discussed herein is the study of the subject literature and the results of a survey conducted among 132 clients of selected cooperative banks. The thesis assumes that financially excluded clients are those who have limited access to the products and services offered by cooperative banks. The following methods were used to develop the test results: structural and χ2 test. Based on the results of the survey, general conclusions were drawn. A small percentage of clients of the selected cooperative banks encountered difficulties in accessing banking services. Financially excluded clients are usually single men, living in the countryside, farm workers or physical workers. Electronic banking services are not very popular among clients of cooperative banks. It is difficult to identify the effect of non-cash trading on the level of financial exclusion of these institutions.
xCoAx 2019: The Variables of Spatial Presence

The term ‘spatial presence’ refers to the feeling of presence in a mediated space. This subjective experience has been discussed in media theory, sound art, film and performance. It depends on multiple variables, or parameters. This paper presents a parametric model that can be used to analyze those variables and their relationships. It exposes methods to assess interaction, characteristics of sound and image, audio-visual relationship and physical setup. It also exposes methods to assess how these variables intertwine in perceptual experience. The model draws from perception science, interaction design, music and audio-visual theory. It is applicable to the broad diversity of aesthetical options and technical platforms, facilitating the analysis of spatial presence in any performance. One can also discard part of the parameters so as to analyze installations, sound art and film.
Cyclovirobuxine D inhibits cell proliferation and migration and induces apoptosis in human glioblastoma multiforme and low-grade glioma

Gliomas are the most common neoplasm of the human central nervous system. Glioblastoma multiforme (GBM) is one of the most serious types of gliomas. Although considerable progress has been made in the development of cancer therapeutic agents, several antineoplastic drugs fail to penetrate the blood-brain barrier (BBB), resulting in a low survival rate of glioma patients. Recent studies have revealed that the traditional Chinese medicine Buxus microphylla contains the main active component Cyclovirobuxine D (CVB-D), which can cross the BBB with a novel delivery system. However, it remains unclear whether CVB-D exerts anticancer effects against GBM and low-grade glioma (LGG). The aim of the present study was to explore the feasibility of CVB-D as a new effective agent in the treatment of GBM and LGG. The ability of CVB-D to inhibit GBM and LGG cell proliferation was detected by CCK8 assay. Flow cytometry was used to detect cell cycle progression and apoptosis induction by Annexin V-FITC/PI assay. The expression levels of the apoptosis-associated proteins, namely cleaved caspase-3 and Bax/Bcl-2, were detected by western blot analysis. The mitochondrial membrane potential (ΔΨm) was detected by Rh123 dyed fluorescence micrograph. Hoechst staining was used to observe the morphological characteristics of the apoptotic cells. The scratch test was used to evaluate the migration of GBM and LGG cells. The results indicated that CVB-D reduced cell viability of T98G and Hs683 cells. Flow cytometry demonstrated that CVB-D-treated cells were arrested at the S phase of their cell cycle. The expression levels of the apoptosis-associated proteins were increased in CVB-D-treated cells. Rh123 and Hoechst staining indicated morphological changes and mitochondrial membrane potential changes of the cells undergoing apoptosis. The data confirmed that CVB-D inhibited cell proliferation by arresting the cell cycle of GBM and LLG cells and that it promoted the induction of cell apoptosis by altering the mitochondrial membrane potential. The findings of the present study indicate the potential value of CVB-D in the treatment of glioma.
Snake venom potency is prey specific with yield driven by snake metabolism and habitat dimensionality.

Snake venom is best known for its ability to incapacitate and kill prey. Yet, potency and the amount of venom available varies greatly across species, ranging from the seemingly harmless to those capable of killing vast numbers of potential prey. This variation is poorly understood, with comparative approaches confounded by the use of atypical prey species as models to measure venom potency. Here, we account for such confounding issues by incorporating the phylogenetic similarity between a snake’s diet and the species used to measure its potency. In a comparative analysis of 102 species we show that snake venom potency is generally prey-specific. We also show that venom yields are lower in species occupying three dimensional environments and increases with body size corresponding to metabolic rate, but faster than predicted from increases in prey size. These results underline the importance of physiological and environmental factors in the evolution of predator traits.
Meaningful Availability

High availability is a critical requirement for cloud applications: if a sytem does not have high availability, users cannot count on it for their critical work. Having a metric that meaningfully captures availability is useful for both users and system developers. It informs users what they should expect of the availability of the application. It informs developers what they should focus on to improve user-experienced availability. This paper presents and evaluates, in the context of Google’s G Suite, a novel availability metric: windowed user-uptime. This metric has two main components. First, it directly models user-perceived availability and avoids the bias in commonly used availability metrics. Second, by simultaneously calculating the availability metric over many windows it can readily distinguish between many short periods of unavailability and fewer but longer periods of unavail-ability.
Clinical Complications of Hemoglobinopathies in Western Saudi Arabia and the Need for Specialized Care Centers

In the absence of specialized care centers for hemoglobinopathies in Saudi Arabia, there are insufficient data on prevalence of clinical complications in this population. This is a retrospective record review about the clinical complications associated with hemoglobinopathies at King Abdulaziz University Hospital, for patients followed between January 1st 2010 through June 30th 2016. A total of 349 patients were included, with a mean age of 25.45 years, including 266 with sickle cell disease and 80 with thalassemia. Of those receiving regular transfusions, 17.5% developed alloantibodies, 16.6% tested positive for hepatitis C virus antibodies and the mean ferritin level was 2487 ng/ml. Almost half of the patients were screened for renal disease, and more than 50% were found to have proteinuria. Of 203 patients with recent echocardiograms, 15.8% had pulmonary hypertension. Thirty-one (8.9%) patients died at a mean age of 28.5 years. In conclusion, the prevalence of disease related complications is high in hemoglobinopathies. Our results reiterate the need for specialized care hemoglobinopathy centers, which can further improve patient outcomes.
Coring the sedimentary expression of the early Toarcian Oceanic Anoxic Event: new stratigraphic records from the Tethys Ocean

Abstract. The Toarcian Oceanic Anoxic Event (T-OAE) interval was cored at Colle di Sogno and Gajum in the Lombardy Basin (Southern Alps, northern Italy). The Sogno and Gajum cores recovered 26.83 and 31.18 stratigraphic metres, respectively, of pelagic sediments consisting of marly limestones, marlstone, marly claystone, and black shale. Drilling at both sites resulted in 100 % recovery of unweathered material. The pelagic succession comprises a relatively expanded black shale interval of 4.98 m in the Sogno core and 15.35 m in the Gajum core, with lower and upper boundaries without evidence of hiatuses. The Sogno and Gajum cores can be considered reference sections for the pelagic lower Toarcian interval of the western Tethys and will provide high-resolution micropaleontological, inorganic and organic geochemical, isotopic multiproxy data. Integrated stratigraphy and cyclostratigraphy are predicted to result in estimates of durations and rates to model the ecosystem resilience to the extreme perturbations of the T-OAE and gain a better understanding of current global changes and help provide better projections of future scenarios.
Speaking Like a State : Knots Untied

This paper discusses some problematic consequences of Turkish modernization as an elitist, state-led process of social transformation. It is suggested that a locally imagined vision of modernity has not yet been observable in Turkey. The preference of the early Republican elite to undervalue local knowledge in designing the nation’s future is interpretively analyzed with reference to two case studies: the movement to purify Turkish language of non-native linguistic elements, and the Village Institutes experiment intended as an Althusserian ideological state apparatus. The paper concludes with a call to radically question the status of the state as the overarching modernizer. A broad lesson is that interventionist state designs only add to the ambiguties, contradictions, and struggles already associated with unilinear imaginations of modernity.
