PRIMARY MYELOPHYBROSIS: RECOGNIZING ONCET TO COMPLICATIONS
Authors: Resti Nimas , Rizki Mohammad , Nurlalwani Dita Kholida
Published: March 2024

Myelofibrosis is the accumulation of scar tissue in the bone marrow so that blood cells cannot develop properly. Myeloproliferative disorders, myelofibrosis is classified into two, namely primary myelofibrosis and secondary myelofibrosis. In contrast to secondary myelofibrosis, primary myelofibrosis can occur without being preceded by myeloproliferative disorders or other diseases. In a 2013 meta-analysis study in Europe, the incidence of primary myelofibrosis (PMF) was around 0.3 per 100,000 per year. PMF may result from increased expression of inflammatory cytokines, lysyl oxidase, transforming growth factor-β, impaired megakaryocyte function, and aberrant JAK-STAT signaling. The most common clinical features found in patients with PMF are splenomegaly, hepatomegaly, fatigue, anemia, leukocytosis, and thrombocytosis. Currently the only treatment modality capable of prolonging survival or healing potential in MF is allogeneic hematopoietic stem cell transplantation (AHSCT) especially for high or very high risk patients.

The need to analyze consumer purchasing patterns using association techniques also lies in the increasingly fierce competition in the retail market. Supermarkets face the challenge of understanding their customers' buying patterns. By utilizing association techniques, supermarkets can identify customer buying trends and quickly and appropriately adjust their strategies. Thus, analyzing consumer purchasing patterns using association techniques is no longer an option but an urgent need for supermarkets that want to survive and thrive in a changing market. Therefore, this study aimed to analyze purchasing patterns in supermarkets using the FP-Growth method to understand purchasing behavior and identify relevant patterns from transaction data. The method used in this research was the FP-Growth association method to create association rules from customer transaction data. The findings of this research were the use of the FP-Growth method in analyzing supermarket customer purchasing patterns, which obtained 10 association rules for 2 itemsets and 11 association rules for 3 itemsets based on a minimum Support value of 30% and a minimum Confidence of 70%. The association rules generated by the FP-Growth method on 2 itemsets and 3 itemsets simultaneously bring up items often purchased by customers with the same pattern, namely Cooking Oil, Eggs, Flour, and Candy. This research concludes that the association rules formed can be used as a benchmark by supermarkets in preparing stock items and making strategies to increase sales for more profit.

Non-alcoholic fatty liver disease and Helicobacter pylori infection: is there a relationship? Review
Authors: Fadieienko G. D. , Gridnyev O. Y. , Gridnieva S. V.
Published: March 2024

The article outlines the relevance of finding a connection between non‑alcoholic fatty liver disease (NAFLD) and Helicobacter pylori infection. The presented data of the majority of studies indicate the presence of Helicobacter pylori infection as a risk factor for the development of NAFLD. In addition, a number of researchers point to the possibility of the influence of Helicobacter pylori on important pathogenetic chains of NAFLD: insulin resistance, the state of the intestinal microbiota, the level of such hormones as ghrelin, leptin, adiponectin, and also that the effect of Helicobacter pylori (H. pylori) toxins can cause direct damage to the liver and that Helicobacter pylori invasion of the small intestine mucosa can increase the permeability of the latter, disrupting the functioning of the gut—liver axis. The article emphasizes the relationship between H. pylori infection and an unfavorable metabolic profile: dyslipidemia, body mass index, blood pressure, fasting blood glucose, and insulin resistance. In addition, research data on the novelty of higher levels of aspartate and alanine aminotransferase in Helicobacter‑positive patients compared to Helicobacter‑negative patients, in the absence of differences in liver fibrosis, are given. Separately, the research data are given, which indicate that the successful eradication of Helicobacter infection does not have a significant effect on liver steatosis, but probably reduces the severity of insulin resistance. Also, the authors draw attention to the fact that in a number of studies, the connection of H. pylori with NAFLD was not found, and no significant differences were found in the levels of high and low‑density lipoprotein cholesterol in people with Helicobacter infection compared to Helicobacter‑negative ones. The authors conclude that today there is no clear understanding of the role of Helicobacter pylori infection in the NAFLD pathogenesis, which requires further research because, after all, most researchers testify in favor of the fact that H. pylori infection can be one of the risk factors, contributing to the emergence and progression of NAFLD, and eradication of H. pylori may be important in the treatment of this disease.

Published: March 2024

In the present work , a numerical study has been made for the developing compressible turbulent flow and heat transfer in circular tube with uniform injection or suction. The study included the numerical solution of the continuity, momentum and energy equations together with the two equations of the (k-ε) turbulence model, by using the Finite Difference Method (FDM). The air was used as the working fluid, and the circular passage was composed of tube with diameter (20.0) cm , and the length was 130 (hydraulic diameter) .The Reynolds number of the flow was (Re=1.78x106 ), and the Mach number (M=0.44) the ratio of the transverse velocity at the wall (vw) to the axial velocity at inlet (Uin), Ω=(vw/Uin), for suction equal(0.001) and for injection (-0.001).. The wall of the tube was heated with constant wall temperature (Tw) and in other case with constant heat flux (Qw) as a thermal boundary condition. The development of both hydrodynamic and thermal boundary layers occurs simultaneously. The computational algorithm is capable of calculating the hydrodynamic parameters such as the velocities , friction factor , turbulence structure which includes the Reynolds stress and the turbulent kinetic energy and eddy viscosity. Besides, the thermal parameters are also predicted, such as the temperature, Nusselt number, and the turbulent heat fluxes.The Results showed that the hydrodynamic and thermal entrance length is increased with the increasing of Reynolds number. The suction caused a flatten for the velocity profile and thus decreasing the hydrodynamic entrance length, and caused an increase in the Nusselt number and decreasing the local coefficient of friction, but injection caused a steeping of the velocity profile , and thus increasing the entrance hydrodynamic length and caused a decrease in the Nusselt number and increase the local coefficient of friction. Turbulent kinetic energy and turbulent heat flux are decreased with suction and increased with injection .Predictions have been obtained which are in good agreement with results obtained by past experimental and theoretical work.

Authors: AL-Hafidh Manal H. , Rishem Ali Mohsen
Published: March 2024

The effect of longitudinal vibration on the laminar forced convection heat transfer in a horizontal tube was studied in the present work. The flow investigated is an internal, laminar, incompressible, developing, steady and oscillatory flow. The vibration vector was parallel to the fluid flow direction. The boundary layer was studied in the entrance region for Prandtl numbers greater than one and the hydrodynamic boundary layer grows faster than thermal boundary layer. The governing equations which used were momentum equation in the axial direction, continuity and energy equation. The finite difference technique was introduced to transform the partial differential equations into algebraic equations and the later equations were solved using the upwind scheme. The vibrational Reynolds number used as indication to the vibration and vibrational velocity which is used as boundary condition. The effect of vibration on laminar forced convection heat transfer is to increase the local and average Nusselt number when the vibrational Reynolds number increases; therefore, heat transfer coefficient increases too. Correlations for local Nusselt number with vibration concluded for constant wall temperature and constant heat flux

Authors: Al-Shakarchi Yousif J. , Fattah Mohammed Yousif , Raheem Aram M.
Published: March 2024

The effective stress method is developed to predict the axial capacity of piles in clay. This method is based on the principle that, at failure, the available shear resistance at the pile soil interface is related to the mean normal effective stress at the pile face and the effective stress friction angle for the soil sliding on the pile material. In this paper, the coupled non-linear finite element method is used to analyze some pile-soil interaction problems. This computer program ( CRISP ) is used for this task. Eight- node isoparametric elements were used for displacements while four- node elements are used for pore pressure. Interface elements are used to simulate the interaction between the pile and the soil. The soil is assumed to follow different models, linear elastic and modified Cam-clay model. A comparison is made between the measured and predicted settlements and excess pore water pressures and good convergence was obtained in which the proposed technique used in this paper, in which the measured excess pore water pressures are considered as initial pore pressures in the computer program ( CRISP ). No load was applied on the pile. The dissipation of excess pore water was studied through carrying out consolidation analysis.

PATTERNS' ANALYSIS

Published: March 2024

It is possible to infer some facts by capturing them directly or trying to trace their evolutions and changes mentally. This will guarantee human beings a sort of self-confidence, control and power. Some sustained patterns of natural, biological and human artifacts provide trusty physical and objective proofs on their success and service. The research claims that the secret beyond the success of these patterns lies in ambiguous or hidden or invisible orders within the seeming randomness and complexity. Successful systems reflect distinguishable order when they reach a critical threshold of stability and self-organizing between their trends to connect and to compact. Then, patterns can reveal themselves and express their similar structural and morphological changes. In the same manner, guiding other systems to reach such edges and thresholds may ensure having successful patterns, solving serious problems and leading the way ahead correctly. The research depends on a new mathematical tool from the Fractal Geometry to reveal and measure the hidden orders in these patterns by calculating the repetitions of form's changes. This tool could be defined as a Fractal Dimension (D), which is considered to be a sensitive index or parameter of the system's behaviors. Also, the research adopts the comparative analysis method of analyze and measure the form of a trusty successful, natural and sustained pattern of a fruit trees orchard, trying to find a numerical order by calculating its fractal dimension. The obtained fractal dimension represents a referential base in analyzing some patterns of urban systems (e.g. Baghdad's two dimensional image), a reliable index and parameter to detect the system's behaviors and trends to connect or to compact. Comparing the pattern of an existing urban fabric for the city of Baghdad with the orchard's pattern refers to an obvious defect in the inner structure and morphology of the capital. Baghdad tends to connect rather than to compact in a pathological way. The research ends with the need for urgent and careful interference to tune the parameters of connectivity and compactivity equally by suitable and practical suggestions and recommendations.

Authors: Al-Omran Asaad T. , Ibrahim Ramzi R. , Al-Rawi H. N.
Published: March 2024

The aim of the present work is to study the effect of different outlet nozzle diameters, by using one or two nozzles on the performance of divergent vortex tube and also to determine the effects of various parameters on the vortex tube cooling performance such as: refrigeration capacity, coefficient of performance, isentropic efficiency. The experimental investigation was carried out on a divergent vortex tube rig manufactured for the present study covering all tests. The effect of different outlet nozzle diameters ( dn= 4 mm, dn = 5 mm, and dn= 6.5 mm) on the performance of the vortex tube is described by using one nozzle or two nozzles by varying the pressure of the inlet air and cold air mass ratio (μc) within the ranges (Pi abs=2 - 7 bar) and (μc= 0 - 1). The outlet nozzle diameter, (dn= 5 mm), and the outlet cold diameter (dc= 10 mm), when using two nozzles, give high temperature separation and may considered to be the optimum for different pressures of the inlet air regarding all the size tube diameter. The experimental study predicts two empirical results between the outlet nozzle diameter (dn), number of nozzles (N), inside vortex tube diameter (D), and length of vortex tube (L)

Published: March 2024

In this research, a procedure to solve problems of unsteady flow to wells in confined aquifers by the computer is developed. The solution is based on the [THEIS:1935] procedure to solve such problems. The developed procedure is applied to (14) different sets of well – test data, including a predicted ideal one. The respective problems are solved completely by the computer without the need to construct or to refer to tables or nomographs; this, accordingly, deletes the role of personal judgment and the need to a high skill.The applications indicate that the developed solution procedure is simple, easy to use, elaborate, superiorly fast in giving the required results, and comparatively accurate. Despite that the developed solution procedure has been set for the case of a pumped well in an ideal confined aquifer, it is basically general; the computer program can be easily modified to fit the solution of problems of the other cases of groundwater flow to wells after introducing the additions that consider the respective boundary conditions

Sustainable architecture has became one of the most important architectural concepts on earthtoday because of the energy crises. Architecture is concerned as the largest energy consuming field ,so that one of the main goals of modern architecture is to reduce energy consumption or reticence it from building if possible . Sustainable architecture is a modern and new concept. It is used sometimes to refer to green ,intelligent and environmental architecture , and that make it confused term , therefore the main goals of this research is to clear the main important pillars of this architectural concept (reduce costs , reduce the environment pollution , reserve energy ) as a first goal. Second goal establishing The Procedural definition for this architectural concept is sustainable architecture is Defined In This Paper As (The Architecture That Satisfies The architectural human needs) – beauty , function , structural needs , the ability to generate energy needed to operate the building or reduce the energy needs for it , reduce the costs of production & maintenance , consumption for environmental conservation purposes to preserve earth and its resources for the future generations. This paper tried also to classify the concept to different levels each one dedicated to specified architectural field . Intelligent sustainable architecture is the one that depends on modern technologies for implement the sustainable concept .Green sustainable architecture is the architecture using plants and green areas ,environmental sustainable architecture is the one depending on environmental features to achieve sustainability. and so on for the rest of levels concepts . As a summery this research is an attempt to understand the concept ( sustainable architecture ) and recognition for its interrelated levels.

In this work, numerical method approach has been used to simulate the solidification parametersof an eutectic aluminum-silicon alloy in chilled metallic mould with copper. The approach is based onthe solution of heat flow equations of the casting and mould. In addition, the latent heat is treated as aboundary condition between the liquid and solid phase. The results showed that different behaviors ofsolidification parameters are obtained along the casting. Furthermore, the simulation approach ofsolidification parameters in conjunction with the microstructure indicated that it is possible, to a largedegree, giving a knowledge about the microstructural features for any alloy system.
THE DEFLECTION CONTROL OF A SIMPLY SUPPORTED THIN BEAM BY USING A PIEZOELECTRIC ACTUATOR / SENSOR
Authors: Al-Ashtari Waleed Kh.
Published: March 2024

Piezoelectric transducers have become increasingly popular in vibration control applications. They are used as sensors and as actuators in structural vibration control systems. They provide excellent actuation and sensing capabilities. In this paper, the term smart beam refers to a beam with a finite number of collocated piezoelectric actuator / sensor pairs. The proposed thin smart beam governing equation was derived by the same procedure that the Bernoulli-Euler equation derived but with some additional mathematical terms to be valid for describing the smart beam. The engineering control techniques were used to obtain the solution of the proposed differential equation for the simply supported beam where with some auxiliary equations and modifications a block diagram for any type of applied load (static, or cyclic) as the input and the beam deflection as the output was constructed. For insuring an efficient reduction in the beam deflection an integrated system with a high voltage amplifier and lead controller was designed. Many cases were studied and simulated including the variation of load nature and its frequency, and the number of collocated piezoelectric actuator/sensor pairs and in all cases a valuable deflection reductions were obtained.

A multi-cells in serial model was developed to simulate the distribution of pollutants (whichare BOD5 and TDS) in Tigris river between Al-A'imma bridge and Al-Jumhuria bridge ,a reachwhich is about (9 km) length within Baghdad city; this includes four sewage pumping stationsuntreated discharged to the river.This region was divided into eleven cells of different volumes. The model was operatedusing the field data, which were obtained from the results of laboratory test of samples which werecollected from twelve stations in the river and four sewage pumping stations located within thestudy region twice a month from 15/11/2005 to 30/4/2006. Verification of the simulation model wasaccomplished by its application to predict the substances concentrations observed.A package program of differential equation were applied to obtain the concentrations ofparameters and modeling the water quality, it was concluded that the concentrations of pollutantswere increased at the discharge points in the river, the concentration of BOD5 reached 140ppm at1.4km from the beginning of the study region, 170ppm at 5km, 160ppm at 6.5km and 155ppm at7.5km, then BOD5 became within the acceptable values in the other regions and finally it reachesthe acceptable value after the last discharge point (7.8km) from the beginning of the study region,TDS was within the acceptable range except at 5km it reaches 1100ppm. sewage pumping stationsshouldn't set at high discharge rate (12 hr/day) to decrease the pollutants concentrations in Tigrisriver in order to keep these concentrations within the acceptable values specially at low flow of theriver (250 m3/sec).By using Surfer program to show the distribution of model results (obtained from theprevious program) and the field results (which were obtained from the laboratory tests) and tocompute the comparison between them.

The objective of this research is to present the numerical analysis of deep foundation system namely controlled modulus columns (CMC) for support of embankments. This paper describes the analysis modeling used for CMC foundation system using the finite element method. The elasto-plastic finite element model used to simulate the embankment soil foundation has been verified against field data. The results obtained from this study showed that the effect of CMC could be negligible when the soil strength increased in terms of its angle of internal friction. With low values of internal friction angle, the CMC reduce the potential of surface deformation about 12%. The values of surface deformation decreased with column diameter until it reach constant value at (0.5m) where less than this values the reduction in deformation could be negligible or have insignificant effect. The maximum deformation was observed at the middle of embankment, also the deformation at the embankment foundation reduce by about (17%) when take into consideration the CMC in soil embankment foundation.
