ESG disclosure, board diversity and ownership: Did the revolution make a difference in Egypt?
Authors: Al Farooque Omar , Dahawy Khaled , Shehata Nermeen , Soliman Mark
Published: February 2022

Egypt witnessed radical and unexpected changes in the political, social and cultural environment that came as a result of the Arab Spring. Since the revolution caused a paradigm shift in so many socio-economic aspects, it is plausible that it also caused dramatic changes in the relationships of board, ownership, and environmental, social, and governance (ESG) practices in different ways. Accordingly, understanding the corporate governance of the largest Arab state in the MENA region following the Arab Spring is a huge benefit. Using the 2011 Egyptian revolution as the exogenous shock, this study empirically examines the effects of board diversity and ownership structure on the ESG disclosure index in the Egyptian Stock Exchange (EGX) listed firms for the pre-revolution (2007–2011) and post-revolution (2012–2014) periods. Using 160 observations for the pre-revolution and 99 observations for the post-revolution periods, we document a significant positive effect of board national diversity on the ESG index in the pre-revolution period. This effect disappears in the post-revolution period. In contrast, we find that board gender diversity shows no significant effect in determining the ESG index in both pre- and post-revolution periods. We additionally find that ownership variables have a positive impact on ESG disclosure in the pre-revolution period. However, this impact is not carried forward to the post-revolution period. Further analysis on moderating effects suggests that the presence of female board members and state ownership can diminish the effective role of foreign board members towards ESG disclosure. These findings can provide policymakers, regulators, investors, and other stakeholders with a broader perspective of corporate board diversity and ownership when aiming to ensure an optimal level of ESG disclosure from listed companies in Egypt or other emerging markets.
Using Automated Suture Fastening System For Securing Aortic Cannulation Sites In Minimally-Invasive Mitral Valve Surgery
Authors: Nasif Abdullah , Masroor Saqib
Published: February 2022

Cor-Knot device is an automated suture fastening system which was
introduced to minimize the operating time during cardiac surgery. It is
currently being used for intracardiac suturing applications such as
implanting valves or rings during aortic and mitral valve surgery
primarily for shortening the procedure time. It also has higher holding
pressures and more consistent holding pressures than manual knots. We
describe here the use of Cor-Knot device in extracardiac suturing to
secure aortic root vent as well as aortic cannulation during minimally
invasive cardiac surgery. A 60-year-old male with mitral valve
endocarditis underwent minimally invasive mitral valve replacement via
right mini thoracotomy. Direct ascending aortic cannulation was
performed through a separate port. Cor-Knots were successfully used to
secure the purse-string sutures after decannulation at the end of the
case.

Harnessing open data and technology for the study of accessibility: The case of Indonesia’s capital site candidate
Authors: Wibowo Budhi , Aditya Rendy , Harianto Tirza
Published: February 2022

Accessibility has garnered substantial attention from transport and urban
planners as the objective of modern transportation systems. However,
analyzing accessibility is often challenging in practice due to extensive
data requirements and computational complexity. The rapid growth of open
data and technology provides new opportunities to perform such analysis in
greater details. This study offers a framework for harnessing open data to
support accessibility analysis. We applied the proposed framework to the
greater area of North Penajam Paser, which is the candidate site to be
Indonesia?s future capital. The results suggest that accessibility mapping
using open data could be an important toolbox in regional analysis,
especially during the early planning phase. It encourages discussions around
the problems and alternative solutions for improving citizen access to
various opportunities.

Grasping the nettle and enduring the pain: healthcare priority setting and disinvestment in the context of prudent healthcare
Authors:   ,   Swansea University, Anderson Pippa
Published: February 2022

Since the financial crisis of 2008 economic pressures mean that healthcare budgets were and still are substantially constrained. The NHS in Wales has had to face the reality of rationing healthcare. Implementation of fair and equitable rationing is a challenge, however. This is a situation where the economic concepts of scarcity, opportunity cost and the margin can support effective prioritisation and resource reallocation decisions. In this context, the aim of this research was to develop pragmatic prioritisation and resource reallocation frameworks for the Welsh Health Specialised Services Committee (WHSSC) who commission highly specialised technologies for Wales and commissioning boards in Abertawe Bro Morgannwg University Health Board (ABMUHB). The prioritisation and resource reallocation methods for WHSSC were developed over a series of prioritisation meetings resulting in a framework based on based on multi-criteria decision analysis methods. In ABMUHB, programme budgeting marginal analysis (PBMA) was the approach used and two pilot PBMAs run in different service areas. Disinvestment and ‘doing less’ to invest in more beneficial activities within budget were accomplished in one pilot project; the other project managed resource reallocation but revealed issues in achieving service standards. Both pilots enabled development of a PBMA Framework for ABMUHB. Group decision support methods were an important feature of implementation of decision making in all three projects. The research conducted for this thesis has shown it has been possible to develop and deliver robust, evidence based, effective and practical frameworks based on economic concepts for prioritisation, disinvestment and resource reallocation. Both organisations have taken ‘ownership’ of the frameworks and will make them a ‘way of working’ for the future rather than an academic exercise. A key learning of the research was that pragmatism must prevail if prioritisation and resource reallocation methods are to gain traction and become embedded in commissioning.

Authors: Mohamadi-Shad Alireza , Niakan Hamed , Manzour Hasan
Published: February 2022

In this paper we proposed a new variable neighborhood search (VNS) for solving the location- routing problem with considering capacitated depots and vehicles. A set of capacitated vehicles, a set of depots with restricted capacities, and associated opening costs, and a set of customers with deterministic demands are given. The problem aims to determine the depots to be opened, fleet assignment to each depot, and the routes to be performed to satisfy the demand of the customers. The objective is to minimize the total costs of the open depots, the setup cost associated with the used vehicles, and transportation cost. We proposed a new VNS which is augmented with a probabilistic acceptance criterion as well as a set of efficient local searches. The computational results implemented on four well-known data sets demonstrate that the proposed algorithm is competitive with other well- known algorithms while reaching many best-known solutions and updating six best new results with reasonable computational time. Conclusions and future research avenues close the paper.

Authors: Baka Marim M. A. , Eryildiz Demet Irkli
Published: February 2022

Libya is completely dependent on non-renewable energy sources (oil and natural gas that increase the problem of global warming) to meet its needs for electric energy. After its decline in its oil production and the destruction of some power stations, especially after 2011, the electricity sector in Libya witnessed a very significant decline, as it could not meet the needs of citizens in all sectors, including the residential sector.

On the other hand, Libya has good solar radiation, as the average solar radiation at the horizontal level is 7.1 kW/m2 in the coastal areas and 8.1 kilowatt / square meters in the southern regions for nine hours per day, and the estimated amount of solar energy available annually is 3.5×109 gig watt hours, which makes it one of the countries that can use solar energy to help meet the increasing demand for electrical energy, and together, this energy is not utilized sufficiently.

This work aims to study the possibility of developing existing residential buildings by installing photovoltaic modules the photovoltaic modules have been integrated with existing buildings in Zuwarah city in different ways: on the building roof to perform functional role and facades for aesthetic role. After studying the existing residential buildings in the city, two samples were chosen as case studies to apply the integration of photovoltaic units to them using Sketch Up software, and the PV Syst software, to design the PV system.

The study clarified the role that photovoltaic systems play in the sustainable architectural formation through their ability to achieve its rules and principles, and the possibility of developing existing residential buildings in Libya - Zuwara by integrating PV with it. As well as its contribution to solving the electricity crisis in Libya.

Published: February 2022

The wastewater treatment plant (WWTPD) located in Durrës, responsible for a treatment area of 205,000 inhabitants, employs the tertiary advanced wasterwater treatment to generate biogas from activated sludge for self use. The biogas collected from the anaerobic digestion tank feed the boiler and the co-generation unit which is then transformed to power its own energy grid. In order to evaluate the quality of biogas produced by anaerobic digestion of WWTPD’s sludge, is measured the percentage of CH4 and CO2 from the biogas production during a three years period (2016 – 2018).

From the performed analyses has resulted a percentage of CH4 up to 75% and 25% CO2 in 2016. While the lowest percentage of CH4 in 2018 with respectively 70% CH4 and 30% CO2.

Based on the value measurements, qualitative results of biogas parameters show that physicochemical and biochemical processes are performed under strict conditions and anaerobic digestion is performed according to standards.

Authors: Berwal Anil K. , Yadav Manisha
Published: February 2022

The expanding commercial building sector and urbanization in India leads to an increase in demand of energy many folds. Consequently, it is the need of the current scenario to define some regulatory regime or policy to harness the enormous potential of energy savings. Under the Energy Conservation Act 2001, the Government of India under the Bureau of Energy Efficiency launched the Energy Conservation Building Code (ECBC) on a voluntary basis. ECBC sets the standards of minimum energy performance for “large commercial buildings. These norms were for both new and existing buildings. Retrofitting of existing buildings offers noteworthy opportunities for reducing global energy consumption and greenhouse gas emissions. This paper provides a systematic approach to review the application of energy conservation building codes in existing buildings and identification of the best retrofit strategies to stimulate the implementation of ECBC in the country.

Microstructured films of undoped zinc oxide (ZnO) and ZnO doped with nickel (ZnO:Ni) were grown by hot filament chemical vapor deposition (HFCVD) technique on Si (100) substrates at 500 °C. Pellets of ZnO and ZnO:NiO as oxidant agenst were used. A shift to the right around 0.17 degree of the X-Ray Diffraction pattern of the ZnO:Ni film was observed with respect to undoped ZnO films. Morphologically by Scanning Electron Microscopy was noticed a Core-Shell type growth in ZnO undoped and a nanostructured type (Nano-wire) in ZnO doped with Ni. Photoluminescence measurements showed an increase in the intensity of the green emission band of ZnO:Ni. It was attributed to defects of oxygen vacancies (VO), zinc vacancies (VZn), zinc interstitials (Zni), oxygen interstitials (Oi), and oxygen vacancies complex (VO complex) in the structure of the film. The incorporation of Ni atoms in the ZnO structure stresses the crystal lattice, leaving behind a large number of surface defects that increase the emission of PL.

Published: February 2022

This study investigated the removal of Lead and Cadmium ions from aqueous solution using activated carbons from agricultural wastes. Activated carbons prepared by chemical activation using Phosphoric acid were characterized by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM) and Brunauer-Emmett-Teller (BET) analysis. The influence of contact time, initial concentration and adsorbent dose which governed the efficiency of the process was ascertained through batch adsorption studies. Adsorption isotherms were determined by correlating with Langmuir and Freundlich isotherms and the kinetic studies were correlated with pseudo first order and pseudo second order equations. The results showed that the amount of Lead and Cadmium adsorbed decreased as the adsorbent dose increased while the adsorption capacity increased with increased in contact time and initial concentration. Activated carbons prepared from Coconut shell and palm kernel (shell and cake) competed favorably with the commercial activated carbon in percentage removal of the metal ions as all the activated carbons had over 90 % removal within 60 minutes when 1g of adsorbent was used. The equilibrium data fitted best into Freundlich isotherms for both metal ions. The rate of adsorption could be described by pseudo second order for all the adsorbents except Coconut shell activated carbon in the adsorption of Lead while intra-particle diffusion was the limiting step for Cadmium adsorption. Therefore, the agricultural by-products can be used as effective, low-cost, and environmentally friendly adsorbents for domestic water treatment in many parts of the world.

Published: February 2022

The replacement of traditional constituents of concrete with waste has garnered a lot of interest due to the increasing demand for natural resources used in concrete production. Hence, this study presents the outcome of an experimental investigation on the effect of partial replacement of Ordinary Portland Cement (OPC) at percentage levels of 0% to 25% in steps of 5%, partial and complete replacement of sand and granite in the percentage of 0 to 50 in steps of 10% with cupola slag and recycled construction aggregates. The fresh and hardened properties of concrete such as workability, compressive strength, and microstructural characteristics were assessed. The test results showed a decrease in workability as the percentage replacement of cupola furnace slag (CFS) and recycled construction aggregates (RCA) increases. Concrete produced at 28 days from the partial replacement of cement and sand with cupola slag has an optimum compressive strength of 20.37 N/mm2 at 10% and 22.81 N/mm2 at 20%, resulting in improved strength of 29.4% and 56.82%, respectively when compared with the control. In contrast, granite’s partial replacement with coarse cupola slag and complete replacement of sand and granite gave a lesser compressive strength when compared with the control samples at 7, 14, 28, and 56 days. The porosity of the concrete with optimum compressive strength from each mix was studied using microscopic and image analysis. The result showed that the addition of cupola slag in granulated and fine forms decreases the porosity, hence leading to higher compressive strength.

Blood disease is a condition in which one or several parts of the blood can’t function normally. Blood disease itself is classified as quite mild but also some are classified as serious diseases and are usually genetic. Sometimes people underestimate the symptoms of mild illnes and lazy to see a doctor or laboratory because they think it troublesome and need to spend money. Therefore an early diagnosis of symptoms that may be related to blood disease is needed, so people can be alert and also prevent severe blodd disease. That’s why we need an expert system application that can help people diagnose and be aware of diseases that related to blood.

Background

The study was designed to evaluate the influence of hyperbaric oxygenation therapy (HBOT) on the parotid gland in patients following radiotherapy for head and neck tumours.

Patients and methods

HBOT response was monitored by 3T magnetic resonance imaging (MRI) using T
2 mapping and subsequent measurement of mean T
2 and T
2 variability as well as by salivary tests (salivary flow, buffer capacity, and pH). Eighteen patients previously treated with irradiation doses between 50 and 80 Gy as well as 18 healthy gender and age matched controls were enrolled. MRI was performed prior to HBOT (40.2 ± 20 months after radiotherapy) and after 20 daily HBOT at 2.5 ATA (absolute atmosphere). Each HBOT consisted of breathing 100% oxygen for 90 minutes.

Results

Significant differences in mean T
2 prior to HBOT were observed between the ipsilateral irradiated (121 ± 20 ms), contralateral parotids (107 ± 21) and control group (96 ± 12 ms). A positive correlation in patients between T
2 variability and irradiation dose was detected in contralateral parotids before HBOT (R = 0.489, p = 0.0287). In addition, negative correlations were observed between mean T
2 in the ipsilateral as well as the contralateral gland and salivary flow before and after HBOT. Negative correlations between mean T
2, T
2 variability and pH of unstimulated saliva were also observed in the sides of parotid before and after HBOT.

Conclusions

The study confirmed that T
2 mapping had a potential for monitoring the differences between irradiated and normal parotid glands. It could also be useful in the assessment of the glandular tissue response to HBOT.
Ultrasound-guided carpal tunnel injections

Background

Carpal tunnel syndrome (CTS), one of the most common entrapment neuropathies, can, in fact, be considered as a socio-economic issue that reduces work productivity, increases disability, and requires prolonged rehabilitation. The imaging modality of choice in CTS imaging is the ultrasound (US), as several morphological parameters can be used in CTS diagnosis and follow-up. In recent years, US-guided CTS injection therapy has become an established treatment option for mild to moderate CTS. The authors of this review performed a literature search that revealed several differences in US-guided carpal tunnel injection in an attempt to unify individual stages of CTS injections protocol for future guidance: patient preparation, injection approach, needle positioning, injected medications, and injectate volume. The three approaches to carpal tunnel injections described in the literature, that is, the ulnar, radial, and longitudinal, can be implemented with single or multiple deposits and different injection volumes. Medications used for injections are corticosteroids, local anaesthetics, dextrose, saline, platelet-rich plasma, and progesterone.

Conclusions

Although no consensus has yet been reached as to which protocol should be used, the ulnar approach with a single deposit injected in large volumes should be considered as the first choice, while dextrose should be the first-line medication option. Furthermore, as terminological differences make it difficult to draw a uniform comparison the presented steps for US-guided carpal tunnel injection might serve as a guideline for future studies.
