Seagrasses have high ecological services as a promoter of biological productivity and biodiversity. When Super Typhoon Yolanda (Haiyan) devastated Tacloban City in 2013, two years after, seagrass beds started to emerge in the shallow waters of Cancabato Bay, Anibong Bay, and San Juanico Straight. Five species of seagrass were identified: Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halodule uninervis and Thalassia hemprichii. Pooled resiliency attributes from literature ...
The right to adequate food is a universal human right that is realized when all people have physical and economic access at all times to adequate food or the means for its procurement, without discrimination of any kind (FAO, United Nations). However, in a rapidly growing population, finite resources, environmental damage, climate change, and global inequality makes this an incredibly complex issue.
ABSTRACT The assessment of the quality of the geophagious ‗Nzu Clay‘ obtained from two hills in Ozanogogo, Ika South LGA, Delta State and Uzella river, Owan West LGA in Edo State Nigeria, with the highest cation exchange capacity, bulk density and dispensability index, 10.800±0.424 meq/100g, 0.915±0.120 gcm-3, 80.00±1.414 respectively was investigated while the pH range from 4.4 to 4.6. The concentrations of heavy metals in ‗Nzu clay‘ obtained from the hill side were signifi...
The soybean cyst nematode is a major contributor to decreased soybean yields every year, and this pest is hard to identify since there are no visible signs of sickness. The only way to detect the nematode is to extract cysts from soil, extract the eggs, and count them. To help alleviate this problem, a robotic instrument has been created to perform the tasks of the conventional manual extraction method. The instrument is managed by a touchscreen software, and its performance is evaluated usin...
The role of phenomenology in architectural design is to create spaces that evoke emotions and have meaning for the individuals who use them. Phenomenology was first introduced to architecture by philosopher and architect Christian Norberg-Schulz in his book "Genius Loci: Towards a Phenomenology of Architecture." Phenomenology informs each stage of the architectural design process, from conceptualization to construction, by focusing on the essence of the user's experience and designing spaces ...
Abstract It is well established that the forces between nucleons are transmitted by meson. The quantitative explanation of nuclear forces in terms of meson theory was extremely tentative & in complete but this theory supplies a valuable point of view . it is fairly certain now that the nucleons within nuclear matter are in a state made rather different from their free condition by the proximity of other nucleons charge independence of nuclear forces demand the existence of neutral meson as ...
ABSTRACT A simple and sensitive spectrophotometric method for the determination of paracetamol was explored, using zirconium(IV) and vanadium(V) oxides. The method was based on the oxidation of paracetamol by zirconium(IV) and vanadium(V) in alkaline and acidic media respectively. The stoichiometric studies indicated a mole-ratio of 1:1 for the reactions of paracetamol with both zirconium(IV) and vanadium(V). Effects of other variables like pH, temperature and time were determined and showed...
ABSTRACT 3D as-built models have been utilized over the years as an aid to several engineering activities and there are conventional survey methods; e.g. Total Station ray method, photogrammetric technique etc., with which the data required for these models are generated. These methods have proven not to be optimal in capturing datasets required for the modeling of some complex engineering structures. The reasons for this been the intrusive nature of some of these methods and their point ra...
Background of the Study Human beings are highly dependent on the natural environment for their livelihood activities. The world has suffered and largely withstood natural disaster throughout its long history. Natural disaster displace and disrupt thousands of families and having more dramatic effect in the poorest of nations crippling what are often already woefully inadequate infrastructure (Delaney et al ., 2004). According to Egboka (2004) flooding is a natural process and can happen...
ABSTRACT Rapid growth of businesses and population in and around Arua town has led to increased production of solid waste consequently giving rise to increased volume of waste dumped in recipient communities. The most attractive and environmentally friendly option to get rid of this huge pileup of garbage and subsequent ones is through composting. The perceptions of recipient communities are crucial to understanding how municipal solid waste management problems might be resolved. Since Arua...
ABSTRACT The removal of Pb(II) ions from aqueous model solution using zeolite has been investigated under different operational parameters like heavy metal ion concentration, adsorbent amount and particle size. The zeolite used was synthesized and characterized using SEM and XRD analysis. The equilibrium adsorption capacity of zeolite used for lead removal were measured and the experimental data analyzed by means of Freundlich and Langmuir isotherm models. The adsorption efficiency of Zeolit...
ABSTRACT The inhibitive effects of bamboo leaves extracts (BLE) on the corrosion of aluminum in 1M HCl were studied using weight loss, adsorption, thermodynamics and kinetic studies. The phytochemical constituents of the BLE were tannins, polyphenols, flavonols, terpenoids, sterols and alkaloids. BLE was noted to contain more of the polyphenols and terpenoids which were largely responsible for the inhibitive action of the extracts. Results obtained from the experiments carried out at 303K a...
ABSTRACT The synthesis of N-heteroaryl substituted benzene sulphonamides and evaluation of their biological activities are reported. Synthesis was achieved by the reaction of benzene sulphonyl chloride and substituted amino heterocycle in dry pyridine. The structures of synthesized compounds were assigned by spectroscopic methods. The eight (8) synthesized compounds were evaluated for antibacterial and antifungal activities. The results showed that some of the new compounds exhibited activit...
ABSTRACT Security is a very vital factor for human growth and development. It has also become a major recent issue in buildings and especially, school buildings. Ensuring security in buildings is a collective endeavour with each individual, government, organization, and community having its own role to play. The architect, who is the master builder, is chiefly responsible in ensuring that the built environment meets requirements of security. This report studied the various techniques of ach...
ABSTRACT The kinetics and mechanisms of the redox reactions of oxidant, m -adipato-di(N,N/ - bis(salicylidene)ethylenediaminatoiron(III),[(Fe-salen)2adi],hereafter denoted as Fe2adi, with the thiols L-cysteine (LSH), thiourea (USH), thioglycolicacid(GSH),2– mercaptobenzothiazole (BTSH) and benzylmercaptan (BSH) have been studied spectrophotometrically at 495 nm in aqueous perchloric acid, I=0.01mol dm-3 (NaClO4) and at 29 ± 1o C. The stoichiometry of 1:1 was obtained for Fe2adi – LSH, F...
