Introduction. Asphalt mixtures are the most widely used road construction material for the arrangement of the top layers of road pavement. Asphalt mixtures are also used to arrange airfield runways, bridges deck surfacing, streets, pedestrian and cycle paths, etc. There is a large number of asphalt mixtures types that differ by grading, the largest nominal aggregate size, crushed stone content, crushed and uncrushed sand content, quality of components, and viscosity of the bitumen binder. Problem statement. The national method for asphalt mixture design is very similar to the Marshall method and the Superpave method in terms of determining the optimal bitumen binder content by the bulk properties of asphalt concrete. The only difference is that, according to the Marshall and Superpave methods, the optimal bitumen content is the one with an air pore content of 4.0 %. However, in accordance with the national method, the design air pore content varies depending on the type of asphalt mixture. A significant innovation of the Superpave method is the determination of asphalt performance indicators, such as rutting resistance, crack resistance, and resistance of the material to fatigue cracking. Apparently, these methods should also be implemented in Ukraine over time. Purpose. Analysis of the methods for asphalt mixtures design. Materials and methods. Analysis of literature sources on various methods of asphalt mixtures design. Results. The analysis of literary sources on different methods of asphalt mixtures design was carried out. Conclusions. The use of different methods of asphalt mixtures compaction can lead to the production of asphalt concrete with different volumetric properties, which will affect both the optimal bitumen content and the performance of asphalt concrete, thus further research should be aimed at defining the effect of the compaction method on the volumetric properties of asphalt concrete and their relationship with the production compaction of asphalt mixtures.

Published: April 2023

Orofacial Granulomatosis (OFG) is a rare clinicopathological entity characterized clinically by the presence of continuous enlargement of the soft tissues of the oral and maxillofacial region and histologically by non-caseating and non-necrotizing granulomatous inammation. The term 'orofacial granulomatosis' has been introduced to indicate the group of various disorders, involving Melkersson-Rosenthal syndrome and granulomatous cheilitis and has been noted to be associated with Sarcoidosis, Crohn's disease and infectious diseases such as Tuberculosis. But, various etiological agents such as food additives, dental materials and microbial agents have been recommended in the disease process. Treatment of orofacial granulomatosis is by corticosteroids but it's not so efcient. It is more important to nd the pathogen rst to specify the appropriate treatment line.
THE POTENTIAL OF TELECOMMUNICATIONS IN CANCER CLINICAL TRIALS: AN OVERVIEW
Authors: Emmanuel Mendoza Orozco José
Published: April 2023

This review article explores the potential benets and challenges of using telecommunications technology, including telemedicine and mobile health apps, in cancer clinical trials. The author conducted a search of four electronic databases for studies published in English between 2010 and 2021 that evaluated the use of telecommunications technology in adult cancer patients and reported patient outcomes. The studies were grouped based on the type of telecommunications technology used, and the outcomes were synthesized to provide an overview of the potential impact of telecommunications technology on cancer clinical trials. Telecommunications technologies were found to improve patient access and recruitment, data collection, management, and analysis, and enable real-time monitoring of patients' health and adherence to treatment. Telecommunications technologies can also reduce trial costs by minimizing the need for inperson visits and other expenses. However, the implementation of telecommunications technologies in clinical trials is not without challenges, including technical issues, patient acceptance and adherence, regulatory and legal approvals, and variability in healthcare systems. The author suggests that addressing these challenges could lead to improved patient outcomes and better overall health outcomes for cancer patients.

Authors: Sankpal Jitendra , Sankpal Sushrut
Published: April 2023

Intussusception is more common in the pediatric age group and very rare in adults. The presentation, etiology and treatment of adult intussusception is different from that in pediatric age group. Adult colonic Intussusceptions account for only 5% of all cases, out of which only 1% present as obstruction. Often the diagnosis in adults is delayed due to vague, chronic and non-specic symptoms that are either ignored or treated symptomatically. Rectal prolapse is more common in geriatric age group compared to younger population. Colonic intussusception can be associated with a rectal prolapse. In children the symptoms of intussusception include palpable abdominal mass, fresh blood in stools and colicky abdominal pain. However, in adults, symptoms consist of bloody stool, constipation or symptoms suggestive of malignancy such as weight loss, altered bowel habits and loss of appetite. We present a case of a complete rectal prolapse with strangulated rectosigmoid intussusception for which sigmoid resection was done with reduction of rectal prolapse, rectosigmoid anastomosis, mesh rectopexy and diverting transverse colostomy

Authors: C Ashwini. , Priscilla David Maria , Saxena Runjhun
Published: April 2023

Background & objectives: Chronic kidney disease (CKD) is progressive reduction in renal function. Renal excretory function can be assessed by measurement of creatinine concentrations in plasma which illustrates the ltration capacity of the glomerulus. The increased serum creatinine levels in CKD patients create a concentration gradient that facilitates increased diffusion of creatinine from serum into the saliva. Saliva has many advantages as a diagnostic media over serum, which includes non-invasive collection, good patient compliance, minimal risk of contracting infection, repeated sampling possible and is cost effective. The purpose of this study was to estimate and correlate serum and salivary creatinine in patients with CKD and to evaluate use of salivary creatinine as an alternative biomarker to serum creatinine in CKD patients. A total sample of 40 subjects aged 25 -6 Methods: 5yrs, inclusive of both genders comprising 20 cases of healthy controls (Group I) and 20 diagnosed cases of CKD (Group II) were selected. 2ml of blood and unstimulated whole saliva was collected from both the groups. The blinded samples were processed in autoanalyzer using Jaffe's kinetic reaction. The collected data were subjected to Statistical analysis. In the present Results: study we found signicant correlation of serum creatinine and salivary creatinine in both controls and CKD. Serum creatinine (6.21 ±4.02) and Salivary creatinine (0.70± 0.61) were both increased in CKD cases compared to Controls Serum creatinine (0.83±0.21) and Salivary creatinine (0.11± 0.07). Serum creatinine and salivary creatinine were xii both increased as CKD progressed. A sensitivity of 75% and specicity of 90% of salivary creatinine was found. We therefore recommend Conclusion: salivary creatinine as a biomarker in CKD and also as an alternative biomarker to serum creatinine in detecting and staging CKD, for assessing disease progression, therapeutic modalities and in screening of large population

Authors: Ratish Chandra G. , Sundar. S Shyam , Kumar Sindhur Praveen
Published: April 2023

Background: Polycythemia in neonates is dened by hematocrit value more than or equal to 65% on venous sample. Polycythemia is associated with hyperviscosity syndrome. In clinical setting,as it is not feasible to measure viscosity of blood, hematocrit value is used as a surrogatefor hyperviscosity. There is a need to evaluate the incidence of polycythemia in SGA babies as SGA is the commonest risk factor for PC followed by pregnancy induced hypertension (PIH) and infant of diabetic mother (IDM). Objectives: To estimate the incidence of polycythemia in 34 to 41week SGA/IUGR neonates and its relation with severity of polycythemia and birth weight-for gestational age-s.d score and its associated morbidity with polycythemia Methodology: Allasymptomatic enrolled neonates will be screened for polycythemia at 2,12, 24, 48 hours of life. Blood sample for hematocrit is obtained by venipuncture (venous hematocrit). These babies will be screened for hypoglycemia, hypocalcemia and where ever applicable for sepsis. The highest hematocrit value of the polycythemic neonates during the course of stay will be considered to study the relationship between severity of polycythemia and birth weight -for gestational-age-s.d score. Results: The Incidence of polycythemia in our study was 16.3%, Distribution based on morbidities associated with polycythemia, the odds of having polycythemia is 4.3 times in those with transient tachypnea of newborn, and it was 8.04 times in respiratory distress syndrome is compared to those without respiratory distress syndrome. Where it was 6.38timesin sepsis compared to those without sepsis, and in meconium aspiration it was 15.02 times compared to those without meconium aspiration. This observation were statistically signicant.Distribution based on morbidity prole of symmetrical and asymmetrical small for gestational age babies, in this study hypothermia was observed in 38 study participants out of which 10 were symmetrical 28 were asymmetrical small for gestational age babies. This observation was not statistically signicant. Conclusions: The prevalence of polycythaemia among SGA babies in the present study was 16.3%.The main problems need to be anticipated in the newborn are perinatal asphyxia, hypothermia, apnea, jaundice, sepsis and hypoglycemia. Improvement of perinatal care is required in order to prevent the birth of SGA babies and also to manage the problems associated with them.

Topology Optimization of Motor Windings for Coreless Electrical Machines
Authors: Thabuis Adrien , Ren Xiaotao , Perriard Yves
Published: April 2023

Coreless electric motors are gaining interest from the community as they have a larger power-to-weight ratio and higher efficiency. The absence of iron slots leaves the winding space unobstructed. It enables the geometry of the coils to be skewed to overlap with their neighbors. This work proposes a topology optimization method to design 3D-printed motor windings aiming for coreless electrical machines with higher motor-constant. A multi-coil interpolation scheme is proposed to design a single coil while accounting for packing with the other ones constituting the winding, without requiring assumptions on the shape or position of the coil. The standard 2-D topology optimization is extended to a 2.5-D one so as to provide more freedom on the achievable geometries while keeping a reasonable computational time. The developed computational design tool generated a novel motor winding with high performance.
When technology does not solve the problem. A Review of “The Charisma Machine” by Morgan G. Ames
Authors: Nnamani Manee Ngozi
Published: April 2023

Although the world has progressed in absolute and relative numbers of schoolchildren, the differences between the richest and the poorest and between rural and urban populations have not decreased. (Schmelkes, 2020). Education inequity is a huge problem that continues to exist worldwide, especially in developing countries, despite the many promising interventions adopted with the hope of closing the divide.. Some authors believe this may result from inadequate policies towards achieving just societies (Schmelkes, 2020). The dynamics that play out between a technological intervention to create equity and the culural components of a community is narrated in the book, “The Charisma Machine”, through the lens of the One Laptop Per Child (OLPC) initiative. This book review summarises the book's main arguments and  suggests some design principles, which could have been adopted by the contributors of the project for a better outcome.
Investigating Reserve Dimensioning Approaches for Multi-Area Reserve Capacity Markets: A Nordic Case Study
Authors: Khodadadi Abolfazl , Nordström Henrik , Eriksson Robert , Söder Lennart
Published: April 2023

This paper investigates Frequency Restoration Reserve (FRR) allocation and dimensioning approaches in a multi-area context, focusing on the Nordic Load-Frequency Control (LFC) block. We aim to (i) provide a framework for multi-area FRR dimensioning applicable to dynamic as well as static approaches, and (ii) enhance the understanding of how the available information impacts the need for FRR capacity. We model the optimal FRR dimensioning and allocation in the entire Nordic LFC block, considering sharing of FRR between areas. We describe how FRR can be dimensioned dynamically, analyse the benefits of moving from a static to a dynamic approach, and investigate the impact of when FRR is dimensioned in terms of the available information. The proposed FRR dimensioning procedure includes a new application of a methodology to simulate imbalance scenarios and a novel reformulation of a chance-constrained optimization problem. Case study results show that dynamic dimensioning of FRR leads to a reduction in total reserve needs compared to the static approach and hence lower balancing costs, especially if FRR is dimensioned after the clearing of the day-ahead market. 
Probabilistic Boolean Operation in Networks of Spiking Neurons for Bayesian Inference of Hidden Markov Models
Authors: Chakraborty Ayan , chakrabarti saswat
Published: April 2023

Spiking neural networks (SNN) have gained popularity among the researchers for low power consumption. An interesting problem on Bayesian inference of hidden Markov models (HMM) on SNN paradigm is timely. In this work we propose a novel approach to address this issue. A probabilistic temporal encoding scheme is adopted and it has been shown that a spiking neuron behaves as a probabilistic Boolean operator. Using this property the posterior of a hidden state is mapped to probability of firing a logic $1$ by a spiking neuron. It has been demonstrated that both binary state HMM as well as multi-state HMMs are implementable using the present approach. The proposed method has been demonstrated to be effective for reasonably accurate estimation of hidden states. The present method seems to be reliable, power efficient and easy to follow.

Authors: Aldallal Ali Abdil Razzaq , Zwain Basim MH.
Published: April 2023

Background: There is an increasing evidence that vitamin D3 improves lung function in respiratory diseased subjects. Higher plasma vitamin D3 concentrations are also linked to better lung function in several communities.
Objectives: To study the effects of single oral vitamin D3 supplementation (600 IU) on lung function in healthy non-smoking young Iraqi subjects.
Methodology: Spirometric tests represented by forced vital capacity (FVC), forced expiratory volume in first one second (FEV1) and forced expiratory volume ratio (FEV%) were done for 82 healthy non-smoking young Iraqi college students (38 males and 44 females) in two occasions one month apart (first and second visits). They were divided into two main groups: Control group (CRL) and Vitamin D3 group (VTD). CRL group contained 42 subjects (18 males and 24 females) who didn't receive oral vitamin D3 supplementation. VTD group contained 40 subjects (20 males and 20 females) who received single oral vitamin D3 supplementation (600 IU). The ages of the study population were the same (20 years) and their heights were not significantly different within each sex.
Results: It was found that FVC and FEV1 (but not FEV%) were significantly higher (of 80 ml to 130 ml) in the second visit than in the first visit in both groups (VTD and CRL) and in either sex (all p<0.05).
Conclusion: Depending on the results of present research; it is concluded that in healthy non-smoking Iraqi subjects; vitamin D3 doesn't seem to have positive effects on Spirometric measurements other than these observed in control subjects.

Pennisetum purpureum Schum., Vigna unguiculata (L.) Walp. and Hyparrhenia diplandra (Hack.) Stapf are fodder plants that can provide quality herbaceous above-ground phytomass for domestic animal feeding. They are used in degraded pasture restoration practices. The objective of this study was to evaluate the mineral elements and nitrogenous matter of these three forage crops. The latter were planted in the pedoclimatic conditions of the Boundji area. Phytomass samples were taken two months after planting by sowing seeds for Vigna unguiculata (L.) Walp., by cuttings for Pennisetum purpureum Schum. and by splitting the stumps for Hyparrhenia diplandra (Hack.) Stapf. The samples were oven-dried at 70 °C to constant weight and chemically analysed. The results obtained show that the mineral elements and nitrogenous matter vary from one forage species to another. Vigna unguiculata (L.) Walp. is the richest forage species in total nitrogenous matter (16.43 ± 2.43%) and digestible nitrogenous matter (117.50 ± 22.64 g/k DM). It provides excellent quality fodder capable of meeting the needs of maintenance, growth, reproduction, gestation and milk production in cattle. Pennisetum purpureum Schum. is the richest grass in total nitrogenous matter (8.43 ± 1.81%) and digestible nitrogenous matter (43.18 ± 16.83 g/kg DM). Pennisetum purpureum Schum. and Hyparrhenia diplandra (Hack.) Stapf produce good quality fodder to meet the vital needs of cattle. These results could be used for the improvement of degraded pastures in order to sustainably manage the pastoral ecosystem.

Amniotic fluid embolism (AFE) is a catastrophic syndrome typically occurring during labor and delivery or immediately postpartum. The pathophysiology of this entity is incompletely understood. The diagnosis of AFE is primarily based on the clinical observations even if not uniform. The classic triad of sudden hypoxia, hypotension, and coagulopathy forms the hallmark of AFE diagnosis. The primary management goal includes rapid maternal cardiopulmonary stabilization with treatment of hypoxia and maintenance of vascular perfusion. We describe the clinical case of a 36-year-old patient admitted for emergency caesarean section for acute fetal distress under spinal anaesthesia. She presents a few minutes after fetal extraction a cardiovascular collapse, sudden respiratory distress and disturbance of consciousness on a massive amniotic fluid embolism. We discuss also the modalities of management of this serious complication.

Renal osteodystrophy is a common complication referring to the skeletal changes associated with the phosphocalcic disorders of chronic uremia in patients with end-stage kidney disease. Uremic leontiasis ossea (ULO) is a rare and severe form of renal osteodystrophy with characteristic overgrowth of the cranial vault and facial bones. Computed tomography (CT) findings are particularly characteristic and include serpiginous tunneling within the maxillofacial bones and cortical bone resorption. The recognition of its radiological appearance and abrupt management are essential to avoid its devastating esthetic and functional impairments. Today's better medical facilities have improved hemodialysis methods, and meticulous patient follow‐up has decreased the incidence of leontiasis. In this paper, we report three rare cases of patients with end stage renal failure who presented with multiple face swellings and were diagnosed with ULO.

Background: Intracanal medicaments used during root canal treatment comes in direct contact with cells of pulp and periapical tissues. The antimicrobial property of calcium hydroxide [Ca(OH)2] is broadly utilized. It has the capability to dissolve organic tissues as well as to inactivate bacterial endotoxins. The aim of this in vitro study is ion diffusion from calcium hydroxide with various herbal pastes through dentin. Materials and Methods: Twenty one extracted single-rooted premolar were selected. The crown was transversely sectioned at the CEJ level. Paste was prepared by using 1gm of calcium hydroxide powder and 2mL of solution. Group1-(n=7): Calcium hydroxide-saline paste, Group2 (n=7): Calcium hydroxide-coconut water paste. Group3-(n=7): Calcium hydroxide-Ashwagandha paste; the apical foramen were sealed with epoxy resin. The teeth were placed in containers with 50mL of deionized water for 24, 72, and 168 hours, the pH values of the solution were measured using a pH meter. Results: Coconut water was alkaline in nature initially and after 168 hours, the medium was still alkaline. Ashwagandha was the only herbal preparation that increased the pH up to 168 hours and made the medium alkaline. Saline water preparations were acidic at the start of experiment, increased the pH up to 72 hours, but could not make the medium alkaline. Conclusion: The present study was done with the aim of vehicle used for calcium paste to improve the diffusion capability. Coconut water has a much better composition of minerals like calcium and zinc. The better dif¬fusion ability and marked antimicrobial activity make them the best materials, which can be used as vehicles. Ashwagandha prepara¬tions provided additional benefits of diffusion of ions through the dentinal tubules in a sustained manner (up to 168 hours) in comparison with normal saline.
Capital Market and its Prospects and Problems in Bangladesh

Published: April 2023

A country's whole financial system may depend on a healthy capital market. Bangladesh's capital market is far less developed than that of many other nations, including those of its neighbors. In 1976, the capital market in Bangladesh was given a new lease of life. The market has been volatile ever since then. In recent years, the market has reached new heights on a near-constant basis. Inadequate financial depth, product diversity, uniformity of the supporting legal and regulatory framework, and similar issues continue to plague the country's capital market despite the many improvements made over the years. Although facing several internal and external obstacles, the market's potential is highlighted in this report. There have been proposals for new policies to inject the market with more energy, making it an instrument of the rapid economic development the government has prioritized.
The Effectiveness of Residual Soil, Orashi River Sand, and Sombrero River Sand as Stabilizing Agents for Subgrade Soil of Highway Pavement

Published: April 2023

The study investigated the effect of different stabilization materials, including residual soil and river sands, on the properties of subgrade soil for road and pavement structures. The results showed that the chemical composition of the subgrade soil was dominated by calcium, aluminum, and silicon, indicating a mineral clay soil. The use of stabilization materials led to a decrease in fines content and an increase in maximum dry density. The behavior of optimum moisture content was non-linear, and the liquid limit of the stabilized subgrade soil decreased significantly for all three materials, indicating a decrease in soil swelling ability. The study also revealed that the use of composite materials of cement and residual soil or river sand can improve the properties of subgrade soil and lead to an increase in unconfined compressive strength. The findings of this study can aid in the selection of appropriate stabilization materials and methods, and in the optimization of the use of these materials in road construction for improved strength and durability. Further research is needed to fully understand the characteristics of subgrade soil and determine the most effective methods for its stabilization and management. This study investigates the effects of residual soil and river sands on the mechanical properties of subgrade soil, with a focus on liquid limit, plastic limit, plasticity index, and unconfined compressive strength. The results suggest that residual soil, Orashi River sand, and Sombrero River sand are effective stabilizing agents for subgrade soil, with an increase in strength observed with increasing percentages of stabilizing material. However, there is an optimum content of stabilization material required to achieve maximum strength values, beyond which the strength decreases. The study also highlights the importance of considering the effect of soaking on the strength of subgrade soil and demonstrates the effectiveness of using composite .........

This case report highlights the risk of renal injury in the presence of a pelvic kidney following blunt abdominal trauma. The case involved a 2-year-old boy who suffered from pelvic tenderness and total macroscopic hematuria after an abdominal blunt trauma. CT scan revealed a left pelvic kidney with a double pyelic system and pyelocal dilatation, coupled with an inferior polar parenchymatous fracture that extended to the excretory tract. The patient initially received conservative treatment, but later developed ureteropelvic junction obstruction, resulting in surgical intervention with a dismembered pyeloplasty. This case highlights the importance of early diagnosis and follow- up imaging for patients with UPJ lesions and the need for conservative treatment options, such as ureteral stenting or percutaneous nephrostomy, to alleviate obstruction and facilitate the healing process. In all cases of conservatively treated renal trauma, rigorous clinical and radiological monitoring is essential.

Published: April 2023

Dural arteriovenous fistulas are rare intracranial vascular malformations with a propensity for hemorrhage. The Cognard classification system is the most widespread classification system wherein type IIB through V must be promptly treated to avoid the risk of hemorrhage. The case presented herein reports a 65 -year-old male presenting with vague non-hemorrhagic neurologic deficits found to have a Cognard type I right dural superior cerebellar arteriovenous fistula. Although quite obvious in retrospect, a DAVF can be missed even by an astute radiologist. This should be considered a “never miss” diagnosis as it carries a risk of intracranial hemorrhage and death.
