Construction of an optical fiber strian gauge
This project is focused on the construction of an optical fiber strain gauge that is based on a strain gauge described by Butter and Hocker. Our gauge is designed to generate an interference pattern from the signals carried on two bare single-mode fibers that are fastened to an aluminum cantilever. When the cantilever experiences flexural stress, the interference pattern should change. By observing this change, it is possible to determine the strain experienced by the cantilever. I describe the design and construction of our optical fiber strain gauge as well as the characterization of different parts of the apparatus

Adsorption of Congo Red Dye from Aqueous Solution onto Natural and Modified Bauxite Clays
The adsorption behavior of congo red dye from its aqueous solutions was investigated onto natural and modified bauxite clays. Both bauxite and modified bauxite are primarily characterized by using, FTIR, SEM, AFM, and XRD. Several variables are studied as a function of adsorption including contact time, adsorbent weight, pH, ionic strength, particle size and temperature under batch adsorption technique. The absorbance of the solution before and after adsorption was measured spectrophotometrically. The equilibrium data fit with Langmuir model of adsorption and the linear regression coefficient R2 is found to be 0.9832 and 0.9630 for natural and modified bauxite respectively at 37.5°C which elucidate the best fitting isotherm model. The general shape of the adsorption isotherm of congo red on natural and modified bauxite is consistent with (H-type) on the Giles classification. Different thermodynamic parameters such as Gibb's free energy, enthalpy and entropy of the on-going adsorption process have also been evaluated. The thermodynamic analyses of the congo red adsorption on natural and modified bauxite indicate that the systems are endothermic in natur
Infecciones del espacio orofacial, etiología, susceptibilidad microbiológica y manejo quirúrgico.
Orofacial infections are considered as one of most common infections and need rapid and adequate treatment as they affect a very delicate region and are associated with serious life-threatening complications. Orofacial infections can be either odontogenic that is with an origin in teeth and associated structures or non-odontogenic, not associated with teeth, can affect facial spaces and spread from one space to another, so a good knowledge about diagnosis and treating these infections is of utmost importance, and can include both non-surgical and surgical treatment. The aim of our study was to determine the most common cause of orofacial infections, the most common bacterial microorganisms and their antibiotic susceptibility. Materials and Methods: A descriptive study was undertaken in the Department of Oral and Maxillofacial Surgery, Al-Shaheed Ghazi Al-Hariry Hospital, Baghdad, Iraq from 1st January to 30th September 2015. This study included 45 patients with different forms of orofacial infections; data regarding age, gender, underlying cause, facial space involvement, presenting signs were collected through history, clinical examination and radiographs, incision and drainage with swab sample for culture and sensitivity test was performed. Results: Patients with orofacial infections showed a female to male ratio of 1.25:1. The mean age was 32.8 years. Most of the patients were in their 4th decade of life (27%). Most infections were odontogenic in origin (62%), the most common facial space involved was submandibular (65%), the most common isolated microorganism was Streptococcus pyogenes (59%), and most patients were treated using an extra-oral surgical approach (78%). Antibiotics to which bacterial isolated showed the most sensitivity were netilmicin, cefoperazone and rifampicin (91%). Pain and limitation of mouth opening gradually decreased in most of patients during the two weeks follow up period. Conclusion: Orofacial infections were more common in females, in the third and fourth decade of life, were odontogenic in origin, were mostly caused by Streptococcus pyogenes, and most isolates were susceptible to netilmicin, cefoperazone and rifampicin. Pain and trismus decreased over two weeks post-treatment.Las infecciones orofaciales se consideran una de las infecciones más comunes y necesitan un tratamiento rápido y adecuado, ya que afectan una región muy delicada y se asocian con complicaciones graves que amenazan la vida.

Lynas Advanced Materials Plant
This case study illustrates the issues regarding Lynas Advanced Material Plant. The Lynas Corporation Ltd of Australia first looked at China before settling on Pahang, Malaysia to establish its rare earth processing plant. Rare earth is a slightly radioactive material. Despite reassurances by the company and the State and Federal governments that the Lynas Advanced Material Plant is not dangerous to the employees and the community, some NGOs and the public are still skeptical. They say the benefits derived from investment may not outweigh the risks. The case presents a balanced perspective on both the benefits and risks of this project

Feature Extraction of Visual Evoked Potentials Using Wavelet Transform and Singular Value Decomposition
Introduction: Brain visual evoked potential (VEP) signals are commonly known to be accompanied by high levels of background noise typically from the spontaneous background brain activity of electroencephalography (EEG) signals. Material and Methods: A model based on dyadic filter bank, discrete wavelet transform (DWT), and singular value decomposition (SVD) was developed to analyze the raw data of visual evoked potentials and extract time-locked signals with external visual stimulation. A bio-amplifier (iERG 100P) and data acquisition system (OMB-DAQ-3000) were utilized to record EEG raw data from the human scalp. MATLAB Data Acquisition Toolbox, Wavelet Toolbox, and Simulink model were employed to analyze EEG signals and extract VEP responses. Results: Results were verified in Simulink environment for the real recorded EEG data. The proposed model allowed precise decomposition and classification of VEP signals through the combined operation of DWT and SVD. DWT was successfully used for the decomposition of VEP signals to different frequencies followed by SVD for feature extraction and classification. Conclusion: The visual and quantitative results indicated that the impact of the proposed technique of combining DWT and SVD was promising. Combining the two techniques led to a two-fold increase in the impact of peak signal to noise ratio of all the tested signals compared to using each technique individually
Crude Palm Oil Corruption: A Discourse on the Imposition of Capital Punishment
The study aims to discuss on the corruption of Crude Palm Oil (CPO) export cases that have led to the scarcity of cooking oil at affordable prices in Indonesia. It is harmful for the public as the Crude Palm Oil (CPO) has been exported without a permit and does not meet the requirements of Domestic Market Obligation (DMO) and Domestic Price Obligation (DPO). The study is a normative legal research employing descriptive-qualitative upon data collected through a library study. The study shows that the case of crude palm oil (CPO) export corruption made the supply of cooking oil disrupted that led to economic and political instability. In response to this, the government conducted an investigation and found several suspects of corruption cases. While the legal process running, the discourse on the application of death penalty arose within the society. It was so because this corruption occurred during the pandemic. However, the use of the capital punishment in cases of corruption is restricted because it can only be used in specified circumstances, especially when the funds are intended for dealing with dangerous situations, national natural disasters, social unrest, economic and monetary problems, and corruption repetition
Basis Set Effects on the Stabilities and Interaction Energies of Small Amide Molecules Adsorbed on Kaolinite Surface
Adsorptions of small amide molecules, acetamide (AA) and N-methyl-acetamide (NMA) on the surface of kaolinite are investigated in this study. The focus is on the basis set effects towards the stabilities and the interaction energies of the molecules on the Al–O surface. With a fixed B3LYP functional, we increased the size of the basis sets for the single-point calculations, to find the converged interaction energies and obtain the relative stabilities. We found that, under the direct usage of Pople-type and Dunning’s correlation consistent basis sets, it is not possible to achieve the pattern of convergence for the interaction energies and the relative stabilities. Compared to the complete basis set (CBS) extrapolation scheme, the double zeta basis sets deviated the most, in the range of 21 to 27%, while it is from 1 to 7% for the triple zeta basis sets. Based on the results, we suggest using 6-311++G(2df,2pd) or cc-pVQZ for energy-related quantities. Compared to AA, NMA attached more strongly by 0.5 eV on the surface of Al–O
