Production of biodegradable polymer matrix biocomposites that are cost effective, sustainable, and environmentally friendly with desirable properties using particles as discontinuous phase (filler) is a welcome development. In this study, bamboo particle reinforced epoxy resin matrix biocomposites were developed by stir casting method. Varied weight percentages (5 to 30 wt. %)  of  100 µm bamboo particles were added separately and blended with an epoxy resin – hardener matrix. The blends were fed into a fabricated wooden mould and allowed to cure at room temperature. After 24 hrs, the specimens were removed from the mould and subjected to microstructural examination using a Scanning Electron Microscope (SEM). Furthe

A new model equation has been constructed to estimate the liquid limit value, using the rapid one point method. Data processing was carried out in Microsoft Excel and SPSS, visualizing and using 6,210 theoretical trial points, which resulted from 135 samples along the actual flow index line, with the number of blows varying from 5 to 50 with an interval of unity. The model has two correction factors (CF), both of which are functions of the number of blows at the trial point in the test. The first CF is applied to the trial moisture content, while the second CF is applied to the previously estimated liquid limit. This technique was checked against real data points. For estimating the liquid limit for a large range of blow

This paper presents a multi-input multi-output (MIMO) high-coupled nonlinear model of a twin-rotor aerodynamic system (TRAS). An optimal sliding mode controller (SMC) is proposed to control the TRAS system. Two optimization algorithms, namely Grey Wolf Optimization (GWO) and Whale Optimization Algorithm (WOA), are used to tune the SMC’s parameters. Which are effectively implemented in this controller. The simulation results are given to demonstrate its effectiveness. To evaluate the performance of the proposed controller, a comparison with a previous study—that used Genetic Algorithm (GA), Particle Swarm Optimization (PSO), and Simulated Annealing (SA) algorithms—has been conducted. The results of the proposed cont

In this paper, soil – pore fluid behavior of a silo under an earthquake loading is investigated. To predict the
response of the silo with the soil surrounding it, ‘the linear-elastic constitutive model’ is adopted with soil
properties; shear modulus and damping ratio; are strains and cycle independent.
A computer program using dynamic stiffness matrix analyses (DSMA) for predicting and analyzing the
model was established using FORTRAN coding. The program is based on geophysical values (such as primary velocity (vp), shear velocity (vs), modulus of elasticity (E), mass density (), shear modulus (G),….etc). The values were obtained from field test results for the soil under a silo located in Kirkuk, Iraq.
To check a

In this research, the possibility of using waste wooden materials (reed and sawdust) was studied to produce sustainable and thermal insulation lightweight building units , which has economic and environmental advantages. This study is intended to produce light weight building units with low thermal conductivity, so it can be used as partitions to improve the thermal insulation in buildings. Waste wooden materials were used as a partial replacement of natural sand, in different percentages (10, 20, 30, and 40) % . The mix proportions were (1:2.5) (cement: fine aggregate) with w/c of 0.4. The values of 28 days oven dry density ranged between (2060-1693) kg/m³.The thermal conductivity decreased from (0.745 to 0.2

Whenever a mathematical model is suggested to classing COVID-19. The population must be divided into several groups and our model has five groups namely S(t), E(t), I(t), V(t) and R(t) which represent susceptible, exposed, inflected, vaccinated and recovered individuals respectively. This model is a continuous dynamical system where the derivative is in fractional form. An analysis solution evaluates the positivity of the functions S(t), E(t), I(t), V(t) and R(t) as solutions of the system. The uniformity of the solutions of the system under consideration is also proved. And finding the equilibrium points. To get acceptable results one needs the solutions. Some of the solutions are points called equilibrium points and th

Low incoming discharge upstream of Samarra-Al Tharthar System leads to sediment accumulation and forming islands, especially an island upstream of Al Tharthar Regulator. This island and the sedimentation threaten the stability of the structure and reduce the efficiency of the system. This study aims to hydraulically identify the sedimentation problem mentioned above, to find solutions of how to control the sediment problems, and to develop the capacity of

The second most commonly diagnosed cancer is colorectal cancer (CRC) is in female. The levels of progranulin, obestatin and liver enzymes including ALT, AST and ALP were measured in forty five sera in female patients suffering from CRC before chemotherapy initiation treatment as G1, G2 after first chemotherapy cycle and G3 after second chemotherapy cycle compared with thirty female as a healthy control G4. Results showed a high significant increased in progranulin concentration and a high significant decrease in obestatin in G2 than other groups. The correlation between progranulin and ALP was a significant negative (-ve) relation while obestatin with AST gave a significant positive (+ve) correlation in G. The results also showed non signif

This study was aimed to estimate the influence of Conocarpus erectus L. residues, and some micronutrients on growth and production of potato. This research was conducted at one of the fields of the College of Agricultural Engineering Sciences - University of Baghdad. The experiment was implemented using factorial arrangement (4X3X3) within randomized complete block design with three replicates. Conocarpus fertilizer was represented the first factor with three levels (7.5, 15, 30 ton.ha-1), which symbolized (C2, C3, C4). Mineral fertilizer as recommended dose as a control, which symbolized (C1). The second factor was foliar spraying with three levels of iron (0, 100, 200 mg.L-1), which symbolized (F0, F1, F2).

     The main goal of this work is to put a simple model of the spectral energy distribution of binary stars called WW Cha. This model is built up on the extracted data from various telescopes and archives for the target WW Cha stars and then analyzing them using a python environment. The result of the fitting proposes that there are two protoplanetary disks around the WW Cha star, with different physical properties for each disk, such as the size of the inner disk being 10 AU, while the size of the outer disk being 300 AU. The shape of the outer disk is a flaring disk not a flat disk according to the value of the power law for the surface density (1.5). The emission in the disk is caused by small amorphous olivine grains rangin

Moisture damage is the most commonly occurring problem, causing layers of asphalt pavements to break apart, reducing the serviceability of roads. The utilization of recycled polymer in asphalt mixtures has become popular because it may offer environmental benefits. The present study aims to investigate how the use of recycled polypropylene (RPP) can reduce the moisture susceptibility of hot mix asphalt (HMA). Asphalt binders were modified with three different concentrations of recycled polypropylene: 1%, 3%, and 5% by weight of the bitumen. The Marshall mix design method was utilized to establish the optimal asphalt content for the specific aggregate gradation both the control and modified mixtures were tested for moistu

Solid waste generation and composition in Baghdad is typically affected by population growth, urbanization, improved economic conditions, changes in lifestyles and social and cultural habits.

A burning chamber was installed to burn cellulosic waste only. It was found that combustion reduced the original volume and weight of cellulosic waste by 97.4% and 85% respectively.

A batch composting study was performed to evaluate the feasibility of co-composting organic food waste with the cellulosic bottom ash in three different weight ratios (w/w) [95/5, 75/25, 50/50].

The composters were kept in controlled aerobic conditions for 7 days. Temperature, moisture, and pH were measured hourly as process succe
