3D PRINTING OF FOAMED CONCRETE DR. RABAB ALLOUZI, UNIVERSITY OF JORDAN ([email protected])
This paper discusses the needs for 3D printing in comparison to conventional construction and the proposed foamed concrete material
for printing. Examples of 3D printing projects under study to overcome housing crisis are presented. Stability and sufficient strength
and structural integrity are the main parameters to look for when looking of printable material. The details of these parameters are
explained in this paper. Foamed concrete exhibits enhanced mechanical, thermal and acoustic characteristics. Such properties seem
to be a suitable alternate choice to fit evolving properties required in the housing industry. Structural response of foamed concrete is
still new including mechanical properties, flexural strength, shear strength, short-term and long-term deflections and are still under

ENVIRONMENTAL AND TECHNOLOGICAL ISSUES
MR. SURESH ALUVIHARA, UNIVERSITY OF PERADENIYA, SRI LANKA ([email protected])
Anthill clay is a distinct soil/clay genre among common soil types because of the stockpiling method. The small particles are carried in and erected an
anthill by a small creature that it is called as termite. In generally, clay is a conspicuous raw material for industrial applications greatly and the assay
of expediencies of anthill clay for advanced material applications were the prospects of the existing research. Carefully collected anthill clay samples
were characterized under the physically and chemically using standard procedures and instruments. The mechanical characteristics of prepared bricks
from anthill clays under 8000C were investigated. As the major outcomes of the existing investigation of raw clays, there were looked to 5.56 of PH
value, 15% of natural moisture content, gap graded and symmetrically distributed arrangement of grains, 60% finer particle percentage (<0.075mm)
according to the weight, composition of Fe, Ti, Ba and K based compounds including Fe minerals with large sorption capacity for other metals. In
addition that 25% of water absorption, 2.62 of bulk specific gravity, 65% of apparent porosity, 21 MPa compressive strength and 0.4 MPa splitting
tensile strength were observed with respect to the bricks which were prepared from the anthill clay. Based on the behaviors of such anthill clay it
should be an influential material in the advanced material manufacturing in the industrial purposes such as the water treatments, rigid materials and
refractors.

A CHARACTERISTIC APPROACH ON THE
SYNTHESIS OF AGRO BASED NANOMATERIALS
DR. N. MUTHULAKSHMI ANDAL, PSGRKCW, INDIA ([email protected])
The ability of nanotechnology to manipulate on atomic scale has extensive impact in various fields of science. This technology contributes in producing
structures, systems and devices possessing innovative properties in view of their sizes. Classification of the nanomaterials play an imperative role in
deciding their specific applications pertaining to their methods of synthesis. Strong combination of two materials resulting in various forms of
microstructures after proper reinforcement lead to nanocomposites of different dimensions. Development of biodegradable, bio renewable
nanocomposites for eco remediation is the prime focus of the study. The key implication concentrates on the clean up of wastewaters enriched with
toxicants which are persistent in the environment and arduous to treat. Bio nanocomposites are synthesized by chemical modification, auto combustion
and ball milling methods, using litter materials like nut shells/ tree barks as precursors. The functionalized nanocomposites were characterized by
FTIR, SEM, EDAX, AFM, XRD, VSM and experimentally verified in the chelation of heavy metal ions [Ni(II), Cr(VI), Cd(II), Pb(II)] and Direct Brown 2 dye
through Batch Equilibration process. Fixed Bed Column Studies were carried out on the basis of Pilot trails under optimized conditions to quantify the
sorption characteristics of the bio nanocomposites. Upscaling of the laboratory results to field levels towards societal benefit was done by designing
and installing FRP columns loaded with the suitable synthesized materials to treat the effluents discharged from electroplating / dyeing industries
located at Coimbatore and Tirupur of Tamil Nadu, India wherein 98% removal of the heavy metal ions and dye molecules was recorded, evidencing
the promising toxicant trapping capabilities of the nanomaterials. Progress in the utilization of novel nanomaterials for the treatment of industrial
effluents would revolutionize water sector domain, as an effective alternate for the infested heavy metal discharges.

ABSTRACT
As many of the developing countries in the world, Sudan depends heavily on the biomass energy sources as a major
source of energy for household and traditional industries sectors. Recently, the biomass energy accounts for more than
(61%) of the total energy consumption in the national energy balance. The dependence on the biomass energy sources
creates serious environmental problems including desertification and climatic changes in many of the rural areas.
Sudan is rich in agricultural residues in both irrigated and rain fed agricultural sectors. The country launched a new
energy and environmentally sound policy to encourage the transfer of advanced sustainable biomass energy
technologies. The policy is based on the optimal and efficient utilization of the available agricultural residues by the
implementation of biomass renewable energy technologies. The main objectives of this paper are to highlight the filed
experience on using biomass gasifier-based project for decentralized power supply for remote location in Gezira State,
Sudan, and to present the challenges facing the large scale applications of the technology in the country. Three types
of biomass were used: Raw Cotton Stalks, Cotton Stalks Briquettes, and Groundnut Shells Briquettes. The efficiency
and the technical performance of the gasifier has been evaluated. The research concluded that gasifier could be one
of the best technical option to convert agricultural biomass products into sustainable energy in rural areas. Biomass
gasification proved that it is a promising technology for dementalization power generation in rural areas (Off-Grid), both
because of difficulties in providing good quality grid power, and due to the wide availability of biomass even in remote
villages in the country. The cotton stalks briquettes were found to be the best biomass sources for the gasification
process. The obtained results give a very encouraging picture to make villages self-sufficient in their primary energy
needs. It is therefore, highly recommended that, an accurate estimation of the potential biomass resources (agricultural.
residues) base in Sudan, should be undertaken for implementation of a decentralized biomass gasification power plants
in rural areas.

Correspondence: Nayef Ghasem ([email protected])
ABSTRACT
Polyethylene production in a gas phase fluidized bed reactor is exposed to unstable temperature behavior, and if not
controlled properly the temperature oscillation can cause polymer melting and potential plant shutdown (Ghasem,
1999). Accordingly, the present work improves the previous simple mathematical model by the CFD modelling that
addresses the prediction of ethylene concentration and temperature profile in entire reactor of the fluidized bed reactor
employed for polyethylene production. The CFD model considers gas phase molecular diffusion in the axial and radial
directions. Results revealed that the size of the internal heat exchanger mainly the exchanger heat transfer interface
area has strong impact on the temperature contour inside the reactor. Ethylene feed rate and ethylene concentration,
catalyst feed rate effect the temperature profile inside the reactor considerably. The increase in ethylene concentration
and catalyst feed rate strongly influences the fluidized bed temperature. As ethylene concentration increases reactor
temperature increases. Proper temperature control inside the polyethylene gas phase is essential fluidized reactor to
maintain the reactor temperature below polymer melting point and hence long term operation of fluidized bed reactor
without reactor shutdown and temperature excursion above the polymer melting point.

ABSTRACT
Wave Energy Converters (WEC) are devices that harvest the different energies that are associated with moving waves,
such as kinetic energy and potential energy, and converting them into useful mechanical and electrical energies.
Considering that the ocean and sea are covering around 71 percent of the earth, it is unavoidable to consider it as the
main source of renewable energy. This report starts with reviewing a few of the most recent WECs. In the analysis
section, it shows a device that functions using pistons to run a hydraulic motor, which then runs a generator in a system.
The device is further modified by attaching a rotating mass, which is directly connected to a generator. It is a hybrid
device using technologies of both the Pelamis and the Penguin. The power output calculated for the system is 177 kW,
which is quiet reasonable considering the wave conditions at Fujairah’s sea shore in United Arab Emirates.

ABSTRACT
Pretreatment is a vital step in the enzymatic hydrolysis of biomass and the successive production of bioethanol. The
present study is focused on thermal pretreatment (boiling & autoclave) methods of low grade and damaged longan
fruits using three different types of the enzymatic sources from commercial cellulase, an enzyme from algae and mixed
enzymes (i.e., commercial cellulase with algal enzyme). Total sugar production after the hydrolysis process from
commercial cellulase, the enzyme from algae and mixed enzymes were 326.41 ± 08.97 g/L, 348.68 ± 01.95 g/L and
368.42 ± 01.16 g/L, respectively. Reducing sugar after the hydrolysis process generated from commercial cellulase,
the enzyme from algae and mixed enzymes was 182.54 ± 03.05 g/L, 183.33 ± 04.70 g/L and 297.78 ± 02.94 g/L,
respectively. Fermentation of these hydrolysate using Saccharomyces cerevisiae TISTR 5020 produced the highest
ethanol production from using commercial cellulase, the enzyme from algae and mixed enzymes was 16.74 ± 0.62 g/L,
5.38 ± 0.54 g/L and 14.32 ± 1.89 g/L, respectively. Consequently, this study suggested that suitable pretreatment and
hydrolysis processes are performing a significant role in bioethanol production from low grade and damaged longan
fruits.

ABSTRACT
The implementation of synthetic dyes give a better efficiency with higher durability; however, the production process of
synthesizing these dyes is more complex, expensive, and involves the use of toxic materials. For these reasons, the
production of such dyes can pose harm not only to humans but also to the environment. An alternative for the synthetic
dyes is the natural dyes or pigment extracted from plants such as anthocyanin, carotenoid, chlorophyll and many others.
These natural dyes are easily extracted from various parts of plants, such as from the fruits, flowers, leaves, and seeds.
Regardless of the limited performance of natural dyes, the natural dyes exhibit advantages including high absorption
coefficients, high light-harvesting efficiency, inexpensive, ecologically friendly, non-toxic, and are easily extractable.
Moreover, this research paper is mainly focused on about extraction of anthocyanin dye pigments from Malabar spinach
fruits for Dye-sensitized solar cells (DSSC). The experiment was conducted using three different methods; extraction of
anthocyanin pigments from Malabar spinach fruits: a.) using pure methanol solvent, b.) using 50% methanol solvent,
and c.) using 50% methanol & 1% HCl solvent, and the resulted data were 160.81 mg/L, 64.62 mg/L and 77.65 mg/L
respectively. It can be concluded that the extraction of anthocyanin pigments from Malabar spinach fruits using pure
methanol solvent has the highest amount of extracted anthocyanin pigment, which is 160 mg/L.

ABSTRACT
Smart time conflict solvers and event time managers are some of the essential tools for educational institutions that
can help students to attend events which might conflict with the lecture or other activity timings to gain advantage of
the opportunities enriching their professional benefits. Usually, a university timetable has certain time conflicts that
remain undiscovered until the time of students’ registration. Therefore, a smart and an innovative approach in terms of
a software package is implemented and described in this paper. The developed software uses smart and efficient
searching methods for achieving an optimum time match between any group of students and under any specified
constraints. Consequently, the devised event organizer can find an optimum time to allocate for the event by finding
the best time at which the majority of the intended people are free for the event. In addition, students who struggle with
time conflicts between two or more courses can also find the most suitable times in which their time conflicts are
resolved. The software searches for classes by locating the time and courses intersections between all the students
who are related to such conflicts. These time conflict processes are difficult to handle manually and may be prone to
errors.

ABSTRACT
Due to enormous application of thick plate and its relevance in engineering, various theories for plate analysis have
been developed using linear strain–displacement expressions. It is proven from previous studies that results obtained
using linear strain–displacement expressions may be unreliable for nonlinear stress and bending analyses. In the
present paper, nonlinear strain–displacement expressions are employed for rectangular plates subjected to uniform
distributed loads to suggest a more reliable refined plate theory that satisfies the continuity of all of the transverse
stress components. This theory, which is based on traditional third-order shear deformation theory of plate is presented
and applied in a bending analysis of rectangular thick plate. Governing equations and associated boundary conditions
of the theory are obtained using the principle of variational calculus. From the formulated expression, the formula for
calculation of the actual critical lateral imposed load, q𝑖𝑤 , on the plate before deflection reaches the specified
maximum specified limit and critical lateral imposed load, q𝑖𝑝 , before plate reaches an elastic yield stress were
obtained. By solving using the formulated expression, the effect of deflection and crack in a mild steel rectangular
plates with opposite edge clamped and the other edge simply supported (CSCS) and simply supported at first and fourth
edge and clamped at second edge and free of support at third edge (SCFS) were analysed and compared. This approach
overcomes the challenges of the conventional practice in the structural analysis/design, which involves checking of
deflection and shear; the process which is proved unreliable. In the result of CSCS plate, the positive value of the critical
lateral imposed load, q𝑖𝑤(between 31.08735 N/mm to 155.4414 N/mm ) before deflection reaches the maximum
specified limit and the critical lateral imposed load, q𝑖𝑝 (between 193.8246 N/mm to 193.8246 N/mm) before mild
steel plate reaches the elastic yield stress, reveals that the plate neither failed in q𝑖𝑤 nor in q𝑖𝑝 for plate span (a) of
1000mm at allowable deflection, wa of 1mm to 5mm.Also, the positive value of critical lateral imposed load
q𝑖𝑤 (between 16.23992 N/mm to 81.20424 N/mm) 𝑎𝑛𝑑 q𝑖𝑝(between 115.3523 N/mm to 115.3523 N/mm) reveals
that the plate neither fail in q𝑖𝑤 nor in q𝑖𝑝 for plate span (a) of 1000mm at allowable deflection, wa of 1mm to 5mm for
SCFS. This means that the plate structure is safe. It is observed that the value of q𝑖𝑝 is constant at any value of wa for
SCFS plate. This means that change in specified deflection limit does not affect the overall performance of SCFS
rectangular plate unlike CSCS plate. Hence, it also reveals that the values of critical lateral imposed loads q𝑖𝑤 𝑎𝑛𝑑 q𝑖𝑝
decrease as the length-width ratio increases. This continues until failure occurs. This means that increase in plate width
increases the chance of failure in a plate structure.It is concluded that the values of critical lateral load obtained by this
theory gives realistic variation of transverse shear stress through the thickness of plate and satisfied the transverse
flexibility of the rectangular plate’s condition while predicting the bending behaviour of isotropic thick rectangular plate.
Therefore, using this theory it is possible to predict actual load that cause the bending behaviour of isotropic rectangular
plate.

ABSTRACT
Air Quality and its management has been quite strained in the past few years and a cumulative approach in dealing
with it would help reduce the emission and enhance the air quality index. As the government focuses on raising in-
house technical capacities, the extent of Micro, Small and Medium Enterprises are shooting up. MSMEs contribute to
majority of the country’s industrial enterprises and considerable amount of its carbon emissions. It is imperative to
concentrate on their environmental impacts based on their energy consumption pattern. However, understanding this
key challenge – the MSMEs are to check on their Energy consumption patterns and the source of energy, thus
eliminating the over-utilization of resources. This would not only make the MSMEs Energy Efficient but also lead to a
decreased emission load and carbon footprint. GHG emission reduction could be mapped over the years. Mapping out
the impact of these ambitious policies and its enablers would be critical. This work would aim at building an advanced
understanding of potential benefits/impacts of MSMEs on the emissions/concentration of air pollutants v/s business
as usual – based on varying levels of Energy Efficient equipment penetration and the fuel being used. This would involve
a combination of Air emissions inventory and dispersion modelling approaches based on scientific understanding of
comprehensive industrial structure in the industrial clusters. Broadly, energy demands and their usage details – coupled
with established local air emissions would be used for establishing a detailed understanding of air quality impacts.

ABSTRACT
Globally, employee voice addresses the notion that people want to be heard because being heard reinforces a sense
of belongingness within an organization; while endearing a belief that a person’s action can have an impact in the
overall productivity of a workplace. This study therefore becomes pertinent in accordance with calls for scholarly
investigation to determine the rate of its impact on the banking sector amid the recent financial recession and
turbulence of the sector. Taking a quantitative method, the descriptive survey research design was adopted for the
study. The findings indicated that employee voice management had a significant positive correlation on workplace
performance of the banking sector (r = 0.597; t = 23.703; F= 561.823; p < 0.05). It concluded that employee voice
management improved job behaviours, industrial relations, and ultimately improved individual and team outcomes. The
study further recommended that the banking sector should increase the autonomy and empowerment of its workforce,
as it spurs their commitment to the workplace.

ABSTRACT
In the article on an example of the tractor-trailer, a load-carrying capacity of 4 tons considers the technique for
calculating the stress-strain state of the trailer frame. The comparative analysis of the results of theoretical and
experimental researches is given. The calculations take into account the specific road conditions of the cotton-
producing countries, which occupy four categories of road sections. The proposed method of calculation of the stress-
strain state of the frame gives a good agreement with the experimental data (maximum values of stress in the range
11%) and can be used in justifying the strength parameters of tractor-trailers.

ABSTRACT
Design-build method has become a more popular procurement method in Indonesia. This method differs from other
conventional procurement methods because the design and construction is one entity. All responsibilities are taken
over by contractors so that the project outcome expected becomes more comprehensive. Design -build applies fast-
track system. The work acceleration implemented during the construction will potentially generate risks on the
performance, in this case quality performance. The implementation of risk management is expected to significantly

ABSTRACT
Recently, dye sensitized solar cells (DSSC) have concerned significant attention attributable to their material
preparation process, architectural and environmental compatibility, also low cost and effective photoelectric conversion
efficiency. Therefore, this study aimed to use potential plant materials for DSSC. This research presents the extraction
of natural pigments from yellow cotton flowers (Cochlospermum regium). In addition, the natural pigments were
revealed that outstanding advantages including a wide absorption range (visible light), easy extraction method, safe,
innocuous pigments, inexpensive, complete biodegradation and ecofriendly. Methanol was used as a solvent extraction
for yellow cotton flower. The chlorophylls and carotenoid pigments extractions were estimated by UV-visible
spectrometer. The chlorophyll-a, chlorophyll-b, and carotenoid yield were 0.719±0.061 µg/ml, 1.484±0.107 µg/ml and
7.743±0.141 µg/ml, respectively. Thus, this study results suggested that yellow cotton flowers containing reasonable
amounts appealable in the DSSC production.

ABSTRACT
Energy use from fossil fuels continues to increase, causing an energy crisis, increasing greenhouse gases, and other
environmental issues. In this study, to obtain renewable energy sources from biomass to replace fossil fuels is vital for
future energy supply. Ethanol production from lignocellulosic materials was gain more attention recently. It is an
interesting process and is an alternative way that countries with agricultural waste can be recycled as energy. To convert
such waste biomass source into energy in the form of ethanol needed necessary to adjust the conversion of cellulose
to different suitability. Therefore, to obtain the fermentable sugars for bioethanol production, the pretreatment process
was involving a vital role. In this experimental study, 4% of calcium oxide (CaO) was applied. Moreover, a scanning
electron microscope (SEM) was used to distinguished the characteristics of untreated and pretreated samples. In this
study, the separated hydrolysis and fermentation (SHF) method was used for bioethanol production. Total and reducing
sugars yield confirmed that tobacco stalks are suitable feedstock for bioethanol production.
Keywords: tobacco stalks, thermochemical pretreatment, calcium oxide, hydrolysis, SEM, SHF.

ABSTRACT
The advancement made in biomedical industry upsurges the consumption rate of pharmaceutical drugs. The lack of
proper monitoring and regulation methods leads to the unregulated discharge of pharmaceuticals in wastewater, where
it can affect the aquatic organisms. Anticancer drugs are also known as cytostatic drugs mainly used for the treatment
of cancer by disrupting the cell function and prevent multiplication of cancerous cell. Therefore, anticancer drugs are
suspected to pose potential risk on environment by influencing mutagenic effects on the cells of aquatic organisms. An
extensive research has been already made in the field of pharmaceutical removal, however their application on the
removal of anticancer drugs is limited. This review paper elucidates about different electrochemical techniques for the
mitigation of cytostatic drugs.
Keywords: Pharmaceutical compounds, anticancer drug, electrochemical oxidation, organic pollutants.

ABSTRACT
The investigations focus on analysing acoustic enclosures intended for noisy Chemical Engineering equipment made
out of natural waste materials namely corn cobs, corn stovers and banana stalks using Actran Software with the
parameters of study being the comparison between different dimensions of enclosure and material properties of
different substances used. Upto 50 Hz frequency, there was no evident distinction in the Pressure-map between two
dimensions of enclosures, while beyond 50 Hz, there was a difference with the larger enclosure encountering greater
pressure intensities as well as greater ranges of pressure intensities. In the frequency range of 40 Hz - 75 Hz for the
smaller enclosure and 30 Hz - 65 Hz for the larger, there was a significant effect of the changing material properties on
the sound absorbing ability of the enclosure. When the two plots of enclosures for changing material properties were
compared, some amount of instability in the graphs of the three materials was encountered at higher frequencies in
the case of the larger enclosure. Upon analysing the results, banana stalks showed better sound absorption potential
followed by corn cobs and corn stovers at frequencies in the range 40 Hz - 70 Hz.
