Exploring the efficacy of sawdust ash as a mineral filler substitute for the production of asphalt mixtures
...Show More Authors

Many waste materials can be repurposed effectively within asphalt concrete to enhance the performance and sustainability of pavement. One of these waste materials is sawdust ash (SDA). This study explores the beneficial use of SDA as a substitute for limestone dust (LD) mineral filler in asphalt concrete. The replacement rate was 0%, 15%, 30%, 45%, and 60% by weight of total mineral filler. Scanning electron microscopy (SEM) was employed to assess the surface morphology of Sawdust (SD), SDA, and LD. In addition, a series of tests, including Marshall stability and flow, indirect tensile strength,moisture susceptibility, and repeated uniaxial loading tests, were conducted to examine the performance characteristics of asphalt mixtures of different SDA content. As per Marshall mix design, a slightly higher binder content was required for the preparation of SDA mixes. The results reveal that the asphalt mixtures prepared using SDA attain a tensile strength ratio (TSR) greater than the critical threshold, i.e., 80%, indicating the feasibility of SDA against moisture- induced damage. The highest TSR value of 87% was obtained using 45% SDA as a replacement for LD. Compared to 0% SDA, there is a reduction of 12.08% in permanent deformation for asphalt mixtures produced with 60% SDA. Also, as the SDA content increases, there is a slight improvement in the resilient modulus values, with a peak improvement of 3% at 60% SDA. In addition, the cost of producing SDA mixes was relatively lower than the control mixes, indicating the cost-effectiveness of using SDA. Overall, the study found that SDA is a promising material that can improve the performance and durability of asphalt concrete at lower production costs.

Serum Chitotriosidase level as a Novel Biomarker for Therapeutic Monitoring of Nephropathic Cystinosis among the Iraqi children
...Show More Authors

Background: Cystinosis is a rare autosomal recessive lysosomal storage disease with high morbidity and mortality. It is caused by mutations in the CTNS gene that encodes the cystine transporter, cystinosin, which leads to lysosomal cystine accumulation. It is the major cause of inherited Fanconi syndrome, and should be suspected in young children with failure to thrive and signs of renal proximal tubular damage. The diagnosis can be missed in infants, because not all signs of renal Fanconi syndrome are present during the first months of life. Elevated white blood cell cystine content is the cornerstone of the diagnosis. Since chitotriosidase (CHIT1 or chitinase-1) is mainly produced by activated macrophages both in normal and inflammator

Changes in the Electroencephalogram as a Biomarker of Alzheimer’s Disease
...Show More Authors

The rapid increase in the number of older people with Alzheimer’s disease (AD) and other forms of dementia represents one of the major challenges to the health and social care systems because of a large number of people affected. Early detection of AD makes it possible for patients to access appropriate services and to benefit from new treatments and therapies, as and when they become available, and to plan for the future. The onset of AD starts many years before the clinical symptoms become clear. A biomarker that can measure the brain changes in this period would be useful for early diagnosis of AD. Potentially, the electroencephalogram (EEG) can play a valuable role in early detection of AD. Damage caused to the brain due to AD leads t

Metaphors and comparisons as a means of rethinking the phenomena of the surrounding world
...Show More Authors

The article characterizes metaphors and comparisons as a means of rethinking the phenomena of the surrounding world; two directions are named within which metaphors and comparisons are studied: 1) the linguo-classification direction combines several classifications of metaphors and comparisons, which are basically focused on comparing two denotations through the meanings of word forms that are part of the trope; 2) the theoretical and conceptual direction is associated with the concept of conceptual displacement and is the basis of the theoretical and methodological study of metaphor and comparison, i.e. the modern theory of metaphor is being formed; The main attention is focused on the comparative concept of Aristotle, which postul

Contributory Factors related to the Tensile Strength of Hot Mix Asphalt Concrete
...Show More Authors

Tensile strength is a critical property of Hot Mix Asphalt (HMA) pavements and is closely related to distresses such as fatigue cracking. This study aims to evaluate methods for assessing fatigue cracking in Asphalt Concrete (AC) mixes. In order to achieve optimum density at different binder contents, the mixes were compressed using a gyratory compactor. Tensile strength was assessed using the Indirect Tensile (IDT) and Semi-Circular Bend (SCB) tests. The results showed that the tensile strength measured by the SCB test was consistently higher than that measured by the IDT test at 25 °C. In addition, the SCB test showed a stronger correlation between increasing binder content and tensile strength. For binder contents ranging from 4

The Iraqi Prose Poem as a Legacy of the Experience of the 1980s Iraq–Iran War
...Show More Authors

The essay investigates the rise and development of the prose poem form in Iraqi poetry in the period during and after the 1980s Iraq–Iran war. The essay follows the legacy of Western experiments with form following the First World War and their impact on the development of form in Iraqi poetry culminating in the prose poem. The dominance of this form on poetic development in this period has a close relationship with the experience of warfare and the ensuing of the cultural changes in Iraq after 1980. Poets of the 1980s war used poetic form as a means of dissent. The prose poem became for them an inherently subversive form that reflected their disaffection with the political, cultural, and literary conflicts of the time. The prose poem in

The Asphalt cement is produced as a by-product from the oil industry; the asphalt must practice further processing to control the percentage of its different ingredients so that it will be suitable for paving process. The objective of this work is to prepare different types of modified Asphalt cement using locally available additives, and subjecting the prepared modified Asphalt cement to testing procedures usually adopted for Asphalt cement, and compare the test results with the specification requirements for the modified Asphalt cement to fulfill the paving process requirements. An attempt was made to prepare the modified Asphalt cement for pavement construction in the laboratory by digesting each of the two penetration grade Asphalt c

Defining the aspects of the local urban sustainability: Eco- cities as a model
...Show More Authors

The absence of ecological perception in the local urbanization resulted in the lack of a clear conception of achieving sustainability in its simplest form in the urban reality and in the city of Baghdad in particular. The research assumes the possibility of achieving urban sustainability in Iraqi cities by applying the cities for the most effective methods to implemented ecological solutions and introducing appropriate urban planning tools and improve the living environment. The research focuses on the ability to define some aspects to achieve a sustainable local urban identity from global experiences. This was performed by proposing a scheduled theoretical framework, through which the features of sustainability can be extrapolated from the
