    Abstract Through this paper, we have highlighted the importance of a Universal Design orientation within the architectural community in Libya; it attempts to shed light on some of the different initiatives, experiences, applications, and projects in the field of accessibility and Universal Design to provide a hospitable urban environment that can accommodate all segments of Libyan society. The paper discusses the difficulties of architectural integration and the need for comprehensive education, training, and proof of concept applications by reviewing some inspiring projects undertaken in Libya to encounter this issue. The paper concludes by looking forward to practicing the design orientation for all in Libya by discussing the opportunities available after the tremendous political and economic change in Libya post-2011 and the need for reconstruction programs that adopt the Universal Design doctrine on suspended and future urban projects, furthermore the need to establish a national strategy, and law binding commitment in this context.

    Abstract X-ray computed tomography (XCT) is regularly employed in geomechanics to non-destructively measure the solid and pore fractions of soil and rock from reconstructed 3D images. With the increasing availability of high-resolution XCT imaging systems, researchers now seek to measure microfabric parameters such as the number and area of interparticle contacts, which can then be used to inform soil behaviour modelling techniques. However, recent research has evidenced that conventional image processing methods consistently overestimate the number and area of interparticle contacts, mainly due to acquisition-driven image artefacts. The present study seeks to address this issue by systematically assessing the role of XCT acquisition parameters in the accurate detection of interparticle contacts. To this end, synchrotron XCT has been applied to a hexagonal close-packed arrangement of glass pellets with and without a prescribed separation between lattice layers. Different values for the number of projections, exposure time, and rotation range have been evaluated. Conventional global grey value thresholding and novel U-Net segmentation methods have been assessed, followed by local refinements at the presumptive contacts, as per recently proposed contact detection routines. The effect of the different acquisition set-ups and segmentation techniques on contact detection performance is presented and discussed, and optimised workflows are proposed.

    Abstract With the rapid advancement of nanotechnology, manipulation and characterization of materials in nano scale have become an obvious part of construction related technology. This review will focus on some of the nanoscopy techniques that are most frequently used in current research of cement based nanostructured materials. In particular scanning electron microscopy, transmission electron microscopy, atomic force microscopy, scanning tunneling microscopy, tomography, scanning transmission X-ray microscopy and laser scanning confocal microscopy are addressed. A number of case studies related to microscopic characterization of nano materials utilizing the aforementioned techniques from the published literature are discussed. While these approaches are beginning to yield promising insight, continued progress will definitely provide a potential sustainable solution for the design, development and promotion towards nanoscale engineering of cementitious materials.

    Abstract Introduction: Pulmonary tuberculosis is a disease that may effect on many organs such as the lung, peritoneum and spread to adjacent lymph nodes in advanced stages, but it is rarely to be as an isolated lymph node without accompanying pulmonary or extra pulmonary tuberculosis in healthy persons.
    Case presentation: A 40 -Years-female presented with a chief complaint of Pain in the lateral side of the Right humerus above the elbow, with no medical history, on clinical examination there was a painful palpable mass in mentioned place. The mass was removed surgically under local anesthesia and sent for pathological autopsy. The result of the pathological autopsy was tuberculosis lymphadenitis. After that, the patient has been sent to a specialized center for tuberculosis to receive the suitable treatment.
    Discussion: More studies should be done to investigate the potential causes of these unusual cases and finding the accurate physiological mechanisms that inhibit the usual manifestations of tuberculosis in these patients to avoid advanced complications.
    Conclusion: Isolated tuberculosis lymphadenitis in healthy persons is unusual case in the literature, which the clinical doctors should be careful in examination the patients who admitting with abnormal lymph nodes and unknown history exposure to tuberculosis. .

    Abstract Introduction: COVID 19 is a new virus appeared in the late of 2019, and spread widely through the world, causing respiratory symptoms and sometimes could cause digestive manifestations.
    Case presentation: We reported a case of a 72 years old women presented with a complaint of dry cough, dyspnea and swollen abdomen, which she diagnosed with COVID19 and her medical history showed type 2 diabetes mellitus and acute kidney injury one month prior to her presentation. CT-abdomen showed Ascites and slightly hepatomegaly then we performed prednisolone antibiotics medication. After a week the Ascites decreased and her condition was good and stable.
    Discussion: Few similar cases have been reported in the literature as case reports, but our article reports the first case report from Syria, which may increase the clinical awareness towards rare complications of COVID19 infection among Syrian clinical doctors, especially pulmonologists.
    Conclusion: The peritoneal effusion consider as s rare digestive manifestation of COVID19 that Clinical doctors should take aware off.

    Abstract Introduction: COVID19 might present as neurological symptoms including headaches, dizziness, anosmia, stroke, and loss of consciousness. Cases with severe COVID-19 are more likely to be complicated by neurological symptoms, but tonic non-colonic convulsion is still a rare presentation of COVID19 as an initial symptom.
    Case presentation: A 23-years old male presented to the ambulance with a complaint of loss of consciousness for more than 1 h and tonic convulsions without clonic movements. The investigations including computed tomography for the brain and chest and lumbar puncture were within normal range and the diagnostic workup concluded that COVID-19 is the cause of the status epilepticus.
    Discussion: Our case demonstrates a tonic non-clonic convulsion as a possible complication for COVID-19 infection as some respiratory viruses can cause neurological symptoms. After excluding the co-incidence of other pathological etiologies, we highly suspect that the seizures in our case are generated by COVID-19 infection.
    Conclusion: This case represents a rare case in the literature review which can increase the awareness of tonic non-clonic seizures and other neurological manifestations as the presenting symptom of the COVID19.
