Anaerobic Digestion and Codigestion of Chlorella Vulgaris Microalgae Biomass with Wastewater Sludge and Dairy Manure for Biogas Production
...Show More Authors

Abstract

 

Anaerobic digestion process of organic materials is biochemical decomposition process done by two types of digestion bacteria in the absence of oxygen resulting in the biogas production, which is produced as a waste product of digestion. The first type of bacteria is known as acidogenic which converts organic waste to fatty acids. The second type of bacteria is called methane creators or methanogenic which transforms the fatty acids to biogas (CH4 and CO2). The considerable amounts of biodegradable constitutes such as carbohydrates, lipids and proteins present in the microalgae biomass make it a suitable substrate for the anaerobic digestion or even co-digested with other organic wastes. The present work investigated methane biogas production by anaerobic codigestion of microalgae, Chlorella vulgaris biomass with organic waste from several sources such as wastewater sludge and dairy manure waste in different proportions as an additional carbon supply to enhance anaerobic digestion and therefore biogas production. Six bottles, employed as batch biodigesters each of 1 liter capacity, were used for that purpose at moderate conditions (35±2 oC). The produced biogas volume was monitored daily along 35 days and the results showed that the daily and cumulative biogas production was increased 4.5 times and 3 times for the bottles with 66.67% microalgae compared with the bottles with wastewater sludge or dairy manure waste only, respectively.

 Keywords: Anaerobic codigestion, biogas; dairy manure, microalgae Chlorella Vulgaris, wastewater sludge.

Chitotriosidase-1 levels in Iraqi Type 2 Diabetic Patients with Thyroid Disorders
...Show More Authors

Study aimed to determination of chitotriosidase-1 levels in Iraqi diabetic and diabetic patients with thyroid disorder. Also, study aimed to found relation correlation for chitotriosidase-1 with FSG, T3, T4 and TSH. Ninety subjects were including in this study. First group consisted of (30) healthy individuals who have no history of any thyroid disorders or diabetes mellitus as control group. Second group (G2) (n=30) patients with diabetic and hyperthyroidism as association disease, and third group (G3) (n=30) include patients with diabetic and hypothyroidism as association disease. Serum used in (FSG, T3, T4, TSH, and Chitotriosidase-1) determination. Results showed a significant elevation in patients’ groups (G2, G3) comparing t

Glucose 6 phosphate dehydrogenase deficiency among neonates with hyperbilirubinaemia in western Iraq
...Show More Authors

Background: Glucose -6-phosphate (G6PD) deficiency seems to be a major cause of neonatal hyperbilirubinaemia. This study was carried out to determine the prevalence of G6PD deficiency among icteric neonates in western Iraq and to evaluate its association with hemolysis in neonatal jaundice.

Patients and Methods: All icteric neonates admitted to Al-Ramadi Maternity and Paediatrics hospital, Al-Anbar governorat, for the period from 1st Feb. to 1st Dec. 2006 were included in the study. Data collected from case records and includes age, sex, total serum bilirubin hemoglobin level, reticulocyte count, blood group and Rh of the mothers and neonates, direct coomb's test and peripheral smear. G6PD enzyme

Optimal Control Problem To Robust Nonlinear Descriptor control Systems with Matching Condition
...Show More Authors

Abstract

    In this paper, the solutions to class of robust non-linear semi-explicit descriptor control systems with matching condition via optimal control strategy are obtained. The optimal control strategy  has been introduced and  developed in the sense that, the optimal control  solution is robust solution to the given non-linear uncertain semi-explicit descriptor control system. The necessary mathematical proofs and remarks as well as  discussions are also proposed. The present approach is step-by-step illustrated by application example to show its effectiveness a and efficiency to compensate  the structure uncertainty in the given semi-explicit (descriptor) control

Feeding Problems in Children with Congenital Heart Diseases in Nasiriya Heart Center
...Show More Authors

Objective: To identify feeding problems of children with congenital heart disease.
Methodology: Non probability (purposive) sample of (65) were selected of 225 children who visit Al Nasiriya
heart center during the period of conducting the pilot study, previously diagnosed with congenital heart
disease.
Results: The study results indicated that children with congenital heart disease have feeding difficulties, low
birth weight , repeated diarrhea , more than half of the sample taking medication for heart disease which cause
repeated vomiting, difficulty taking liquids and refusal of feeding or eating.(64.6%) of study sample suffered
from wasting. (78.5%) suffered from stunting. Almost half of the study sample suffered

Two Primary brain Tumurs in a patient with minimalComplaint a case report.
...Show More Authors

Background: Multiple tumors in the nervous system is a rare event..
Patient & Method: .A forty two years old male who was enjoying completely healthy life presented with one week history of a single attack of confusion .he was presented with double tumour in the brain operated up on our department by craniotomy.
Results: His neurological clinical examination was negative. A CT scan & MRI of the brain showed two intracranial space occupying lesions. A solid right frontal lesion and another cystic lesion in the third ventricle. . The pathology proved the frontal lesion to be a meningioma while the third ventricular tumour was colloid cyst. Post operative period was uneventful. Follow up for few months showed no complaint.

Arsenic Detection Using Surface Plasmon Resonance Sensor With Hydrous Ferric Oxide Layer
...Show More Authors
Abstract<p>The lethality of inorganic arsenic (As) and the threat it poses have made the development of efficient As detection systems a vital necessity. This research work demonstrates a sensing layer made of hydrous ferric oxide (Fe<sub>2</sub>H<sub>2</sub>O<sub>4</sub>) to detect As(III) and As(V) ions in a surface plasmon resonance system. The sensor conceptualizes on the strength of Fe<sub>2</sub>H<sub>2</sub>O<sub>4</sub> to absorb As ions and the interaction of plasmon resonance towards the changes occurring on the sensing layer. Detection sensitivity values for As(III) and As(V) were 1.083 °·ppb<sup>−1</sup> and 0.922 °·ppb<jats></jats></p> ... Show More
