Published: May 2021

Global warming and climate variability are emerging as the foremost environmental problems in the 21st century, especially in developing countries. Full knowledge of key climate change variables is crucial in managing water resources in river basins. This study examines the variability of air temperature and rainfall in the five states of South-Eastern region of Nigeria, using the trend analysis approach. For this purpose, temporal trends in annual rainfall and temperature were detected using non-parametric Mann-Kendall test at 5% significance level. The time series rainfall and temperature data for the period 1922-2008 were analyzed statistically for each state separately. The results of Mann Kendall test showed that there is trend in rainfall in all the capital cities in South-East except Owerri and Awka. It is also observed that the trend of rainfall is decreasing for all the study areas in South-East with the lowest trend rate of -0.1153 mm rainfall occurring in Umuahia. In the case of air temperature, it is observed that the trend is increasing for all the study areas in South-East with the highest trend rate of 0.04698 oC/year occurring in Enugu. These findings provide valuable information for assessing the influence of changes on air temperature and rainfall on water resources and references for water management in the South-Eastern river basin of Nigeria. It also proved that Mann-Kendall technique is an effective tool in analyzing temperature and rainfall trends in a regional watershed. Doi: 10.28991/cej-2021-03091692 Full Text: PDF

Published: May 2021

Water is one of the main constituents of concrete. Although many types of water exist, fresh water is the mostly used in concrete industry. Fresh water is expected to be in a great shortage by 2050 according to UN world water development report. Incorporating seawater in concrete mixture can help in the expected problem of scarcity of fresh water. Also, in many cases seawater may be the only available water especially in coastal regions. Many reports mention various possibilities of using seawater in concrete without detrimental effect on concrete properties. In this study another beneficial effect of seawater over tap water was concluded. Setting tests of cement paste mixed with seawater was determined using Vicat apparatus and compared to tap water. Compressive strength tests at the age of 28 days of Portland cement concretes with varied quantity of cement i.e. 300, 350, 400, 450, and 500 kg, and mixed with seawater was also performed and compared to tap water. The results show that seawater affects standard consistency of cement paste and two percent increase was required in order to attain the same consistency as tap water. It shows also seawater slightly accelerates initial setting of cement but the effect is not so pronounced so as to cause a trouble in concrete and final setting time almost remains unaltered. Compressive strength tests show an increase in concrete strength mixed with seawater for all tested mixtures and depending on quantity of cement. It also shows a beneficial effect of seawater on compressive strength of rich concrete with quantity of cement 450 and 500 kg over tap water. Doi: 10.28991/cej-2021-03091695 Full Text: PDF
A New Simplified Prediction Method of the Contact State between Shallow Foundations and Swelling Ground
Authors: Farid Z. , Lamdouar N. , Bouziyane J. Ben 
Published: May 2021

Prediction of the contact state between soil and structure is a key step in any study of shallow foundations resting on swelling soil. However, in practice, the foundation designer has no simple and rapid method, at the design stage, to define the contact conditions. This study presents a new method, both simple and reliable, to predict the contact state. To do this, a soil-structure interaction model is developed. The building behavior is investigated with the Euler–Bernoulli beam theory and the ground behavior is investigated with a Winkler model. The soil-structure interaction is then, studied at the equilibrium state. The thereby obtained equation is analyzed and all of its parameters are synthesized in a new factor named "Detachment Factor". The decidability of the contact is thus reduced to the study of this single element, which allows a reasonable approach to the knowledge of the surface rate engaged in the shallow footings - expansive soil interactions. The conclusions of the current study are validated against five cases treated in the literature in various regions around the world. In addition, a parametric study of the “Detachment Factor” shows that each of its parameters (i.e. swelling stiffness, shape of initial soil surface, permissible deflection, structure geometry and loads) has a variable effect on the contact state between a footing and swelling ground. But, the structure load has the most significant effect on it. Doi: 10.28991/cej-2021-03091697 Full Text: PDF

Due to a high construction material cost in Ethiopia, it is difficult to afford a shelter by most our peoples. The Hydra form block (HFB) has been identified as low-cost building material with its potential and possibility to reverse the housing problem. Laboratory tests were conducted on Mettu, Nopa, Gore, and Hurumu areas soil. Using hydra form machine with average mold size of 29*14*10cm, hydra form blocks were casted with the three percentages increment of cement. Compressive strength and water absorption tests were conducted at 28 days. The investigation has revealed that all the soil sample except Gore soil have significant characteristics that make it suitable for stabilization with recommended soil properties. From the experimental study, all the blocks except blocks produced with Gore soil have 28th day compressive strength values well above most of the recommended minimum values. Water absorption was less than the maximum limit of 15%. But, for control block and for stabilized with 3% cement, water absorption result is out of the recommended values (0-15) %. The cost comparison of Hydra form blocks with hollow concrete block and fired clay brick shows that the Hydra form block is cheapest walling material in terms of production cost and a typical hydra form block production center can create a job for more than 50 peoples.
Double-barrel STA-MCA bypass for cerebral revascularization: lessons learned from a 10-year experience

OBJECTIVE
In select patients, extracranial-intracranial (EC-IC) bypass remains an important tool for cerebral revascularization. Traditionally, superficial temporal artery–middle cerebral artery (STA-MCA) bypass was performed using one limb of the STA only. In an attempt to augment flow and to direct flow to different ischemic areas of the brain, the authors adopted a “double-barrel” technique in which both branches of the STA are used to revascularize distinct MCA territories.

METHODS
A series of consecutive double-barrel STA-MCA bypasses performed between 2010 and 2020 were reviewed. Each anastomosis was directed to augment flow to a territory most at risk based on preoperative perfusion studies, cerebral angiography, and intraoperative indocyanine green data. CT perfusion and CTA were routinely used to evaluate postoperative augmentation and graft patency. Patient perioperative outcomes, surgical complications, and modified Rankin Scale (mRS) scores at the last follow-up were reported.

RESULTS
Forty-four patients (16 males, 28 females) successfully underwent double-barrel STA-MCA bypass on 54 cerebral hemispheres: 28 operations were for moyamoya disease, 23 for atherosclerotic disease refractory to medical therapy, 2 for complex cerebral aneurysms, and 1 for carotid occlusion as a sequela of cavernous meningioma growth. Ten patients underwent multiple operations, 9 of whom had moyamoya disease/syndrome, with the subsequent operation on the contralateral hemisphere. The average patient age at surgery was 45.1 years (range 14–73 years), with a mean follow-up time of 22.1 months. Intraoperative graft patency was confirmed in 100% of cases, and 101 (98.1%) of the 103 anastomoses with imaging follow-up were patent. Perfusion to the revascularized hemisphere was improved in 88.2% of cases. Perioperative ischemic and hemorrhagic complications occurred in 8 procedures (2 were asymptomatic), whereas remote ischemic and hemorrhagic events occurred in 7 cases. There was no mortality in the series, and the mean patient mRS scores were 1.72 at presentation and 1.15 at the last follow-up.

CONCLUSIONS
The high rates of intraoperative and postoperative patency support the feasibility of dual-anastomosis STA-MCA bypass for revascularization. The perioperative complication rate is not significantly different from that of single-anastomosis bypass. The functional outcomes at follow-up and perfusion improvement postoperatively support the efficacy and safety of this method as a treatment strategy.

Authors: Brahmini A. , Sankarganesh A. 
Published: May 2021

Background: The effectiveness of standard chest physiotherapy (CPT) has been confirmed by many studies. Airway CPT is considered the base of physiotherapy and is characterized as “gold standard” of physiotherapy. Chest physiotherapy is a routinely used therapy to prevent post-operative pulmonary complications after abdominal surgery. There are different types of devices used to deliver PEP but one of the most commonly used is Acapella. It has more stable wave form and a wider range of PEP at low air flow.
Objective: To find out the effect of hemodynamic response to acapella in abdominal surgery patients.
Methodology: Study design is Quasi experimental, study type is pre-test - post-test type, and sampling method is convenient sampling, sample size is 36, study duration of 4 weeks, study setting in SRM medical college hospital research centre, Kattankulathur. Procedure: Acapella device was selected depending upon the patient’s ability to maintain an expiratory flow of 15 litres per minute. Patients were explained with complete procedure prior to examination. Mouthpiece was used during exhalation. Patients were asked to breath from diaphragm taking deep breath. Hold breath for 2-3 seconds. They were asked to Perform 10-20 PEP breaths and then asked to remove the mouthpiece and perform 2-3 ‘huffs’ coughs to raise secretions as needed. This was repeated 3- 4 times. Results: There is no significant improvement by using acapella in systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, arterial oxygen saturation rate.
Conclusion: This study concludes that there was an increase in hemodynamic variables during the usage of acapella which return back to normal values in post 30 minutes of training. Thus, acapella is safe, effective to use for airway clearance.
Key words: abdominal surgery, acapella, airway clearance, hemodynamics.
