Opis:
The antimicrobial activity of methanolic and aqueous extracts of Chrysophyllum albidum fruits was investigated against clinical isolates(Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia and Candida albicans). Qualitative phytochemistry of the plant indicated that the plant contained Flavonoids, Steroids, Alkaloids, Tannin, Anthraquinone and Cardiac glycosides while Saponins were reported absent. The maximum activity of the aqueous extracts in the test isolates was observed on Staphylococcus aureus, which showed clear zones with diameters of 24.0mm, 20.0mm and 16.5mm at concentrations of 100mg/ml, 50mg/ml and 25mg/ml respectively while it had low activity on Klebsiella pneumonia, with clear zones of inhibition of 15.0mm, 12.0mm and 10.5mm at same concentrations. On the other hand, Methanolic extracts activity on Staphylococcus aureus produced clear zones of 21.0mm, 17.5mm and 12.0mm at concentrations of 200mg/ml, 100mg/ml and 50mg/ml respectively as its best activity while the it had least observed activity on Klebsiella pneumonia with clear zones of 14.0mm, 11.5mm and 10.5mm at same concentrations. The aqueous extracts had greater activity than the methanolic extracts at same concentrations. Therefore, the fruit of the plant can be a good source of remedy in phytomedicine.

Opis:
Quantitative analysis/interpretation was undetaken on an aeromagnetic data covering latitude 6°00’-6°30’N and longitude 7°00’-7°30’E of Mmaku area, South Eastern, Nigeria by means of spectral depth analysis and Euler Deconvolution. To determine the sedimentary thickness or the depth to basement peculiar within the area, regional-residual separation was applied on the total aeromagnetic data. The resulting residual was divided into overlapping sixteen (16) spectral grids using Ms Excel. This was saved in Comma Separated Variable (CSV) format and thus imported into Origin Pro software where Fast Fourier Transform (FFT) or spectral analysis was performed on the windowed or gridded residual. The residual data was also imported into Oasis Montaj software for Standard 3D Euler Deconvolution. The result of the spectral analysis shows that the depth to various causative sources vary from 3.472 km to 6.972 km for the deeper sources, with average thickness of 5.010 km and 1.177 km to 1.834 km for the shallower sources, with average value of 1.047 km. From the Euler depth solutions, depth values ranging from 1525.74 km to 2919.21 km was revealed using structural index (SI) of 1 while depth values of 2290.49 km to 4447.62 km and 925. 93 km to 5790.49 km was observed when SI of 2 and 3 respectively were chosen. This study presents, therefore, suitable sedimentary thickness for hydrocarbon exploration to exist within the area.

Opis:
The philosophical basis of a legal system is the determinant factor of the content and focus of the legislation and judicial decision emanating from the legal system operating within the society. The focus of every legal system should be the pursuit of a society where men’s ambition is actualise within the purview of accepted norms and values guiding the people within the society. The aim of this paper is to examine the concept of morality and law, the intricate relationship between the two concepts and the moral contents in the Nigeria legal system. The methodology adopted is basically doctrinal with the primary source from various legislation and case laws. The secondary source includes articles in journal, internet sources, bible, etc. The paper concludes that there is no distinction between morality and the law but that the two concepts should be seen as complementary to each other in terms of regulating human behaviours. It is also our conclusion that a critical examination of Nigeria legal system through her legislations and judicial decisions is predicated on the basis that law and morality are two sides of the same coin.

The focus of this research is to delineate subsurface structures as well as their edges by interpreting a high resolution aeromagnetic data via qualitative approach. The study area lies between Latitude 6°00’- 6°30’N and Longitude 7°00’ - 7°30’E in Enugu state, south-east Nigeria. Regional-residual separation algorithm was applied on the total magnetic intensity aeromagnetic map in order to generate the residual and regional maps. On the resulting residual data, further enhancement techniques like the upward continuation at 5 km, 10 km and 20 km, band pass, high pass and low pass enhancement technique/filtering actions were undertaken. Result of the qualitative analysis shows that the study area is characterized by numerous faults and fractures expressed as NNE-SSW, E-W, N-S, NE-SW, NW-SE, and ENE-WSW tectonic trends. The NE-SW and NW-SE tectonic trends indicate that the area is affected by the charcot and oceanic fractures that existed within offshore Niger Delta, Nigeria while the ENE-WSW. NNE-SSW, E-W and N-S tectonic trends exemplify that the separation of Africa from South America affected the area.

Opis:
Road Traffic Accidents (RTAs) are common occurrences on Nigeria roads and Ibadan is not an exception. Non-availability of facilities to take the injured to the nearest hospitals necessitated this study. The study looked at the role played by Demand-Responsive Transportation System in Road Traffic Accidents in part of Ibadan with a view to reduce deaths caused by the inability of the available system on ground to rescue the injured from the scene of the accidents to the nearest hospitals for immediate first aid or outright treatment. The aim is to locate an accident scene, the nearest hospital and the shortest route to the hospital with facilities to treat the victims. The study adopted Remote Sensing and GIS methods to acquire both primary and secondary data and used ArcGIS 10.3 software for the processing of the data and performed geospatial analyses to produce information for a Decision Support System. Twenty three hospitals and eleven accident scenes were considered. The hospitals have the basic facilities to take care of victims of Road Traffic Accidents within the study area. The study revealed that 63.64% of the total Road Traffic Accidents’ scenes in the study area occur on the Dual carriage ways while the remaining 36.36% occurred on the single lane roads. The travel distances range from 1.4 Km to 3.3 Km between one of the accident scenes and twelve of the hospitals. The number of hospitals available to attend to the RTA victims within an accident scene are between 0 and 6 when a distance of 1Km is considered and can be more with increase in the travel distance but should rather be shorter because of danger in travelling farther with injured victims. There are also overlaps because of the distribution of the accident scenes and the hospitals in the study area.

Opis:
India is a rich cultural country in which diverse cultural and religious festivals are organized. Idol is an image of a god which is used as an object of worship. After worshipped, these idols are immersed into water bodies. Idols are constructed by plaster of paris, clay, cloths, small iron rods, bamboo and decorated with different paints such as varnish, water colors etc. which can lead to significant alteration in the water quality after immersion. Paints which are used to colour these idols contains various heavy metals such as Mercury, Cadmium, Arsenic, Zinc, Chromium and Lead. Particularly, red, blue, orange and green colours contain mercury, zinc oxide, chromium and lead, which are potent carcinogens. Two heavy metals such as Lead and Chromium also add in the water bodies through Sindoor (a traditional red colored cosmetic powder, usually worn by married women and often used in the festivals). The floating materials released through idol in the river and lake after decomposition result in eutrophication, increase in acidity and heavy metal concentration. Heavy metal pollution caused by idol immersion can damage the ecosystem as it kills fishes, damages plants, blocks the natural flow of the water, causing stagnation. The effects of idol immersion on various water bodies of India like Bhoj wetland, Budhabalanga river, Ganges river, Hussainsagar lake, Kolar river, Sarayu river, Tapi river, Chhatri lake, north and west lakes of Bangalore and Yamuna river have been observed so far. Investigations were carried out to find out the effects of immersion of idols on water quality by collecting and analyzing the water samples from the immersion sites of the rivers. The samplings were done before the immersion, on the day of immersion and after the event and several parameters like Temperature, pH, Dissolved Oxygen, BOD, Dissolved CO2, Conductivity, Salinity, Alkalinity, TDS, Total Hardness, Chlorides etc. are estimated. Most of the studies found significant changes in the water quality parameters during and after immersions. Central Pollution Control Board has formulated guidelines on the practice of idol immersion in water bodies, which should be followed for controlling pollution.

Opis:
Annona muricata is a recognized medicinal plant species. Despite its usefulness, adequate attention has not been given to its propagation and cultivation. Therefore, this study investigates the effect of some rooting hormones on juvenile stem cuttings of Annona muricata. Uniform, healthy, single node leafy stem cuttings were obtained from eighty (80) uniformly growing seedlings. The cuttings were treated with 1mg/ml of Indole Acetic Acid (IAA), 1 mg/ml of Indole Butyric Acid (IBA), coconut water and distilled water as control, using the quick dip method. The percentage survival of the cuttings, percentage of die back, number of new roots formed per cutting, length of new roots formed, and number of new shoot were assessed after 60 days. Results obtained revealed that the species responded differently to the four treatments. Coconut water had the highest survivor percentage (100%) and IBA had the lowest (25%). Coconut water had the highest mean number of roots (5.25) and IBA had the least (1.75), but there was no significant difference between the values obtained from IBA and distilled water. IAA had the highest mean value (1.80) for new shoots, while IBA had the least value and there was no significant difference between the values obtained from coconut water and distilled water. Significant differences, however, did abound in the root length. Coconut water had the highest mean root length value (4.70 cm), followed by distilled water (1.95 cm), while IBA had 1.55 cm and IAA had the least value (0.80 cm). Thus the use of coconut water might enhance the development of stem cuttings of Annona muricata.

Opis:
This study aimed at the simultaneous treatment of wastewater obtained from swine and generation of bioenergy in form of electricity from the energy stored in the organic component of the wastewater. The Open circuit voltage, current, power density and microbiological and physicochemical parameters were monitored. An initial Open circuit voltage of 516mV, Current of 0.29mA, and Power density of 32.74mW/m2 were recorded, which increased to give maximum Open Circuit Voltages of 836mV, Current of 0.49mA, and Power density of 88.45mW/m2. The results revealed that The Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Organic carbon, Total Soluble solids (TSS), Ammonia, Ammonium and Ammonium-Nitrogen all showed percentage decrease of 85.92%, 51.74%, 78.16%, 98.87%, 55.87%, 55.79% and 55.90% respectively while parameters such as Total Dissolved Solids (TDS), Nitrate, Nitrate-Nitrogen, Phosphates, Phosphorus and Orthophosphates however increased after treatment to give a percentage increase of -273.60%, -131.65%, -134.85%, -168.77%, -159.26%, and -157.03% respectively. Bacteria isolates identified at the biofilms on the anode were Corynebacterium specie, Bacillus specie, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Streptococcus faecalis. The results from this study further exacerbate the Bioelectricity production as well as wastewater treatment potentials of the Microbial Fuel Cell technology.

The capacity of Microbial fuel cells (MFCs) to produce voltage and concurrently treat abattoir waste water was investigated in MFCs that used 0.1M potassium ferricyanide (K3[Fe(CN)6] as catholytes. Physicochemical, electrochemical and Microbiological properties of the MFCs were monitored. The open circuit voltage (OCV) readings were taken at 3 hours interval and maximum OCV of 965mV was recorded. Also, The physicochemical characteristics of the MFCs revealed that the pH decreased by 0.2 after treatment; Chemical Oxygen demand, biochemical oxygen demand, total suspended solids, ammonia, and total nitrogen reduced by 88.4%, 65.56%, 43.88%, 60% and 60% respectively. However, Phosphate increased by 54%. The bacterial isolates from the raw abattoir wastewater were Staphylococcus aureus, Bacillus cereus, Bacillus subtilis, Enterococcus faecalis, Enterobacter aerogenes, Escherichia coli and Micrococcus luteus while Enterococcus faecalis, Bacillus cereus and Escherichia coli were isolated from the biofilms on the anode. Microbial fuel cells therefore have capacities for simultaneous waste water treatment and electricity generation.

Opis:
Lately, different therapy strategies for treating or slowing the progression of Alzheimer's disease are being analyzed. Moreover, the last two decades have seen a considerable research effort directed towards discovering the causes of Alzheimer's disease with the ultimate hope of developing safe and effective pharmacological treatments. In addition to the therapeutic strategies based on targeted drugs, the regimens will require the simultaneous application of neuroprotective drugs. Therefore, although there is currently no "cure" for Alzheimer's disease, a large number of potential therapeutic strategies emerged lately. In this small mini-review we will selectively describe some of the compounds derived from plants that could have a great potential in the treatment of various diseases, including Alzheimer's disease. In this way, there are many plant species that have been traditionally used for memory disorders. The differentiated results and powerful activity of these extracts are making these neuroprotective strategies to be somehow plausible for the treatment of Alzheimer's disease. In addition, these plants can be examined in order to isolate and identify their active ingredients and this can serve as a starting point to find safer and more effective agents for therapeutic use. On thing is certain: as the effective treatment options are limited, there is a demand for new drugs. Thus, plant extracts or vegetal compounds could represent an important part in this equation.

Opis:
The human microbiome is a complex collection of microorganisms, including their genes and the metabolites colonizing the human body, and playing various functions in health and disease. The arrival of culture-independent molecular techniques such as metagenomics, transcriptomics, proteomics, and metabolomics have removed the limitations imposed by culture-dependent techniques. These advanced techniques have also brought about some paradigm shifts in what is known about the structural and functional diversities of the human microbiome in health and disease. The dynamics of the human microbiome is implicated in a number of human gastrointestinal and non-gastrointestinal diseases. This makes it a contemporary issue in biological and medical sciences. Of interest, some applications have already emerged for the human microbiome. These include being the source of antimicrobial substances, faecal microbiome therapy, probiotics, prebiotics and phage therapy. Given that a number of factors can alter the host microbiome - such as environment, lifestyle, stage of life, occupation, mode of delivery, therapy and so on, there is a need for more human microbiome projects that will help to capture these diversities in various continents. Furthermore, for the full impact of the various applications (both potentials and current) of human microbiome to be felt, there is need for more studies that will fully elucidate their physiology in humans.
