Wolfing Sustenance from Disturbed Wetlands

After Super Typhoon Yolanda (Haiyan), the people of Tacloban City, Philippines, must survive and sustain human existence. In an ecosystem devastated from its original state, Taclobanons had to subsidize the resources that were left. Wetlands as being the source of food yet could be a source of threat as the alteration of the quality of the waters due to the accumulation of sediments after the deadly storm surge. Moreso, food preparation methods could also be a pressing avenue for health hazar...

Resiliency of seagrass beds in shallow waters of Tacloban City, Philippines after super Typhoon Yolanda

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 literatur...

Resilient Seagrass in the Realm of Climate Change

Though seagrasses had been confronted with adverse conditions brought on by climate change and resulting in their drastic decline all over the world, some of their attributes showed resiliency. When Tacloban City, Philippines, was devastated by Super Typhoon Yolanda (Haiyan) a year after, seagrass emerged even without restoration. Various literature also observed this resiliency when sea-level rises, even as carbon dioxide and temperature increase. Though confronted with challenges, both natu...

Microcosm between Seagrass and Bare Patches Supporting Communities of Gastropods and Bivalves after a Large-Scale Disturbance

In an ecosystem that had experienced large-scale disturbance such as the Supertyphoon Haiyan in 2013, four years after, gastropods and bivalves were started to be amassed by local gleaners in seagrass and bare patches in shallow waters of Tacloban City. In order to compare which among the two microcosms would have a higher abundance, four stations were established along the coastlines of Burayan, San Jose, Magsaysay Boulevard, Anibong and Caliro, Diit; laying two 50- meters transect lines in ...

Food Security and its Challenges

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.

Physico-Chemical And Heavy Metals Assessment Of ‘Nzu Clay’ And Its Effect On Hairs Of Consumers

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...

Robotic Instrument to Extract Worm Eggs from Soil

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...

How do Spaces Become Special: An Analysis of Phenomenology in Architecture

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 ...

New Formula of Nuclear Force

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 ...

Spectrophotometric Determination of Paracetamol using Zirconium (Iv) Oxide and Ammonium Trioxovanadate (V)

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...

As-Built Surveying for the Facility Retrofitting of an Offshore Gas Plant using Leica Scanstation 2 High Definition Surveying Instrument

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...

ASSESS THE IMPACTS OF FLOOD ON LIVELIHOOD IN DONGA LOCAL GOVERNMENT AREA OF TARABA STATE, NORTHEAST NIGERIA

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...

Community Perceptions towards Compositing of Municipal Solid Waste in Ewuata Village, Eruba Parish, Vura Subcounty in Arua District

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...

Synthesis, Characterization and Use of Zeolite in Removal of Pb(Ii) Ions from Waste Water

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...
