Influence of Different Factors on Permanent Deformation of Hot Asphalt Concrete Mixtures
Authors: Albayati Amjad H. , Al-Mosawe Hasan 
Published: December 2023

Abstract
The performance of flexible pavements is significantly impacted by the permanent deformation (rutting) of asphalt pavements. The research aims was to evaluate the permanent deformation of asphalt mixtures under different conditions. To achieve this aim, 108 cylindrical specimens have been prepared and tested under repeated loading in uniaxial compression mode. Five factors were considered in this research. They include testing temperature, loading conditions (stress level and duration), and mixture properties (bitumen type and content). The permanent deformation is evaluated in term of the following parameters, permanent micro strain εp, resilient micro strain εr, initial permanent strain (intercept, a), accumulation rate of permanent deformation (slope, b), rate of decrease in permanent deformation α and constant of proportionality between permanent and elastic strains Mu. The test results showed that the εp and a are increased as the testing temperature increased. In addition, the εp value for load duration of 0.4 s is 1.64 times the value for 0.1 s. Finally, the findings showed that the resilient response of the material is comparatively more sensitive to bitumen content than the plastic response. Furthermore, the rutting resistance is highly affected by the variables considered in this research.

Published: December 2023

Abstract
The article presents the possibilities of utilizing waste from the automotive industry, namely old tires, in constructing pavements. The application of shredded rubber creates conditions for devulcanization, which improves the rheological properties of the binder and ensures its better dissolution in asphalt. The focus is on assessing the condition of the pavement surface, measuring the noise level in the vicinity of the road, and quantifying and evaluating the cost of implementing an asphalt pavement design with a crumb rubber modifier (CRM). A visual inspection was performed after 6 years of pavement life. Based on the inspection outputs, the pavement surface structure was in a favourable condition with no permanent deformations. Verifying the acoustic properties showed a noise reduction compared to the road section with the modified asphalt pavement surface. Currently, the price of rubber-modified asphalt for pavement in Slovakia is on average 10 to 15 % higher than the price of other modified mixes. However, we can conclude that pavements with CRM are economically and especially ecologically more advantageous in the long run.

Abstract
Soils that exhibit high volume change when its water content is changed are considered collapsible soils. Gypseous soils are one of the main types of collapsible soils which can be found in arid and semiarid areas. In this study, the effect of initial water content on the collapsibility properties of natural and treated gypseous soils with 5% of cement is experimentally investigated. The soils tested at different initial moisture content i.e. 5 %, 10 %, 15 %, 20 %. Two types of soil were used with different gypsum content 28.43 % and 43.62 % named soil 1 and soil 2 respectively. The soils were taken from Tikrit city in Saladin governorate – Iraq. The results show that the initial water content has significant effect on the collapse potential. The reduction in collapse for natural soils reaches up to 70 % when the initial water content was 20 %. Furthermore, the reduction in collapse for natural soils was greater than that for treated soils with different initial water content. It can be concluded that increasing initial water content can reduce the sudden collapse which is a major problem.

Abstract
Additives added to the flexible pavement mixture aim to increase the strength of the pavement. Limestone which is a sedimentary rock consists of the mineral calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). The use of limestone in pavement mixtures is expected to increase the performance of Marshall parameters. This study aims to determine the suitability of limestone as a filler for 3 types of pavement mixtures, namely Asphalt Concrete Wearing Course, Hot Rolled Sheet and Split Mastic Asphalt. In this study, the limestone used was sourced from Jorong Durian, Nagari Kamang Mudiak, Kamang Magek District, Agam Regency, West Sumatra Province. The tests were carried out using following variations of limestone; 0%, 25%, 50%, 75%, 100% of the total amount of filler in the mixture. The results of the study using limestone as filler obtained at an optimum content of 29% for AC-WC, 22% for HRS, and 82.5% for SMA. In addition, AC-WC pavement was found to the best increase in Marshall stability performance. Therefore, it can be concluded that limestone from Kamang Mudiak is most suitable to be added to AC-WC pavement mixtures.

Published: December 2023

Abstract
Soil swelling in road layer is the complex phenomenon. The paper aims to derive a concise expression for two challenging design parameters when the subgrade layer is expansive in geotextile-reinforced unpaved road. The design parameters considered in the present study are the mobilized bearing capacity and swelling pressure for expansive soil. Herein the dimensional analysis via Buckingham’s π method is applied to derive the design parameters by forming the dimensionless group for prototype and model system. The model testing for the swelling pressure and mobilized bearing capacity are carried out in the laboratory by using consolidometer ring and CBR set up. The test results reveal the swelling pressure of 22.03kN/m2 for the soil sample having 76% as degree of saturation. A linear relation is observed between swelling pressure and degree of saturation and becomes equal upon surcharge. The mobilized bearing capacity for the expansive soil sample is 0.47kg/cm2. The failure pattern observed during testing is general shear failure in unsoaked condition and punching soil failure in soaked condition. The paper provides geometric ratio of 1:6 for model and prototype and also suggests modification in Giroud and Han generic equation by including the developed dimensionless group.
Vairimorpha apis Versus Vairimorpha ceranae, Replacement or Dynamic Prevalence?
Authors: Galajda Richard , Sabo Rastislav 
Published: December 2023

Abstract
Nosematosis is currently a frequently discussed disease of bees caused by two species of microsporidia: Vairimorpha apis, and Vairimorpha ceranae. Vairimorpha apis represents the original species of Apis mellifera parasite, and Vairimorpha ceranae, is a species introduced from Asia. In the last two decades, epidemiological data on the growth of the prevalence of V. ceranae infection have increased, which has led to its dominant position at the expense of its congener V. apis, practically all over the world. This process is assumed to be the result of asymmetric competition within the host, where V. ceranae, showed a better ability to adapt to higher temperatures, which was first manifested by its spread in warmer climate zones. However, several results of studies from recent years somewhat unexpectedly showed that it is premature to talk about the complete replacement of V. apis by V. ceranae. They pointed to a greater influence of seasonality and average temperatures in winter and summer in a given year on the result of the current prevalence of infection and co-infection of Vairimorpha spp., regardless of the climatic zone in which the colonies were located. Considering the different clinical and subclinical manifestations of infection caused by V. apis, and V. ceranae, and its impact on the defense, survival and productivity of bee colonies, the aim of our work was to analyze the factors affecting the distribution and prevalence of Vairimorpha spp.

Abstract
This study aimed to assess the impact of pregnancy on biochemical indices of dairy cows raised in a semi-arid region of western Algeria. A private farm provided forty dairy cows for this study. The cows were divided into four groups based on their pregnancy stages: G1 included pregnant cows at 3 months, G2 included pregnant cows at 6 months, G3 included pregnant cows at 9 months, and G4 included lactating (calving) cows for 1‒2 months. All of the cows were raised under the same environmental and management conditions, following the regional customs. Twelve biochemical parameters were measured, including cholesterol (CHO), triglycerides (TG), total protein (TP), albumin (Alb), globulin (Glob), urea (Urea), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), calcium (Ca), phosphorus (P), and magnesium (Mg). The results of the study showed no significant difference (P > 0.05), in the concentrations of various biochemical constituents, among the four groups of dairy cows. The mean value of Glob slightly increased in early pregnancy, compared to late pregnancy, and non-pregnant cows. AST exhibited a significant difference, between non-pregnant, and early-pregnant cows. ALT levels significant decreased in late pregnant cows, compared with early-pregnant cows. Additionally, Ca levels showed a slight increase, during late pregnancy, compared to non-pregnant cows. As this is the first study of its kind on dairy cows in Algeria, the data generated during this research demonstrated the good management of the herd and can serve as valuable reference values for the scientific community.

Authors: Kubiś Piotr , Kuźmak Jacek 
Published: December 2023

Abstract

Introduction
Bovine herpesvirus 6 (BoHV6) belongs to the Herpesviridae family, Gammaherpesvirinae subfamily and Macavirus genus. It is common in cattle, but was also detected in American bison (Bison bison) and water buffalo (Bubalus bubalis). The aim of the experiment was to develop an ELISA for serological examination of cattle sera for the presence of anti-BoHV6 specific antibodies.

Material and Methods
Viral DNA from a BoHV6-positive cow was amplified by qPCR and the resulting fragments of the gB and gH genes encoding glycoproteins B and H (gB and gH) were cloned into the pLATE52 vector to express recombinant gB (rgB) and gH (rgH) in Rosetta (DE3) E. coli. The expressed recombinant proteins were used as antigens in the developed ELISA.

Results
The proteins expressed had the expected molecular weight. A total of 143 sera were examined, and 141 of them were positive, according to the chosen cut-off values of 9% and 10% for the sample-to-positive ratios of the rgB and rgH antigens, respectively.

Conclusion
The rgB and rgH recombinant antigens of BoHV6 were successfully expressed in E. coli and successfully used in a newly developed ELISA.

Published: December 2023

Abstract
A 43-year-old woman with a recent history of confirmed hepatitis B presented with yellow sclera and dyspnea. Clinically, she had tachycardia and tachypnea as well as signs of jaundice and right upper quadrant pain. She was in sinus rhythm with a normal aspect of cardiac examination. She was treated with corticosteroids and her symptoms were partially relieved, however, her mild fever remained unchanged and a transthoracic echocardiogram (TTE) and transesophageal echocardiography (TEE) were done to rule out embolic or in situ infective endocarditis. Images from the TEE and TTE showed a ping-pong-like clot in the left atrium with a normal cardiac function and a normal mitral valve function. The mitral leaflets appeared to be normal with no regurgitation, and no clot was noted in other chambers or valves, including the atrial appendages. A differential diagnosis of infective vegetations, clots, or tumors was considered. The three subsequent blood cultures were negative. A complete thrombophilia assay revealed a severe reduced protein C factor, however, the IgG anti cardiolipin and lupus anticoagulant were normal. The woman’s anti-nuclear antibody and anti-double-stranded DNA were negative, confirming the diagnosis of acquired protein C deficiency. The patient underwent an open surgical removal of the clot and postoperative treatment with steroids, warfarin, and heparin. The postoperative course was uneventful, and the patient was discharged on the 13th day of operation in good condition. This case was interesting because we did not find any mitral valve pathology such as mitral stenosis, or arrhythmia like atrial fibrillation.

Published: December 2023

Background:
Blood culture-negative infective endocarditis (BCNIE) refers to infective endocarditis (IE) with negative microorganism growth using the usual blood culture method. It poses a dilemma in terms of diagnosis, associated complications, and treatment. The study aims to highlight the occurrence of acute bilateral lower limb ischemia in BCNIE and its management approach.

Case Presentation:
We present a BCNIE patient who developed acute bilateral lower limb ischemia, Rutherford stage 2b despite on course of antibiotic treatment. The patient underwent emergency bilateral open femoral embolectomy and right profundaplasty. A full 6-week course of antibiotics and short-term anticoagulants successfully reverses the acute ischemic event.

Conclusion:
This case highlighted that despite the rarity of BCNIE causing limb ischemia, it can still occur due to significant risk factors. The early recognition of acute limb ischemia and prompt treatment are deemed important in saving the threatened limb from being amputated.

Influence of Door Gap on Aeroacoustics and Structural Response of a Cavity
Authors: Bacci David , Saddington Alistair J. 
Published: December 2023

Numerical aeroacoustic analysis using the Shear Stress Transport–Scale Adaptive Simulation turbulence model was conducted on a weapon bay model based on the M219 geometry with doors incorporating radar cross-section reduction features. The effect of the introduction of a gap between the doors and the cavity edge on the aeroacoustic and structural response of the cavity was analyzed at Mach 0.85. The effect of introducing 3 deg of sideslip was also investigated. Both mean and unsteady flow analyses were conducted. The results showed a strong palliative effect of the door gap with and without sideslips. The overall analysis of the spectral signature on the forces and moments acting on the doors indicated the possibility of fluid–acoustic coupling, as all acoustic spectra showed a predominant tone located at the same frequency of the first structural mode.
