    The genus Olios Walckenaer, 1837 is revised, a generic diagnosis is given and an identification key to eight species groups is provided.

    Melorheostosis is a rare osteosclerotic bone dysplasia. It is usually characterized by dull and aching pain, reduced joint motion and contractures. Classic radiograph findings are of undulating cortical hyperostosis along the length of the bone, simulating a "dripping candlewax appearance". We report two cases of melorheostosis of the ulna bone, diagnosed 6 years apart in two different females in their early 20s. Both the patients presented with the characteristic features of dull and aching pain in the forearm and were treated conservatively. However, we misdiagnosed the first case as bone malignancy and subjected the patient to a biopsy. For the second case, with hindsight we made the correct diagnosis based only on the classic clinical history and radiographs. We believe that the discussion of a misdiagnosed case of melorheostosis with salient findings may be important for clinicians and orthopedicians in day-to-day clinical practice.

    This study aims to explore the impact of the Covid-19 pandemic on tourists' travel risk and management perceptions. Driven on the effect of the pandemic, we investigate tourists' travel risk and management perceptions and its effect on society using a sample of 716 respondents. The data was collected through social media platforms using a representative sampling method and analyzed applying the PLS-SEM tool. The findings reveal that Covid-19 pandemic has greatly affected travel risk and management perceptions. Travel risk and management perception had a significant association with risk management, service delivery, transportation patterns, distribution channels, avoidance of overpopulated destinations, and hygiene and safety. The results also identified the mediating effect of travel risk and management perceptions. The finding of this study contributes to tourism crises and provides future research insights in the travel and tourism sector and response to change tourists' travel risk and management perceptions in the post-covid recovery period.

    Gastric metastasis from breast carcinoma is uncommon and rarely encountered in our daily practice. We report a case of late gastric metastasis from previous infiltrating lobular carcinoma of the breast. The patient had extended disease-free interval of 22 years prior to metastasis. Gastroscopy and fluoroscopy showed changes appearing like linitis plastica of the body of the stomach. Computed tomography of the thorax and abdomen demonstrated pulmonary metastasis and mediastinal lymphadenopathy. Biopsy of the mediastinal lymph node and stomach lesion confirmed metastatic adenocarcinoma from breast carcinoma based on immunohistochemistry staining. Immunohistochemistry staining of both specimens revealed strong positivity for cytokeratin 7 and negative for cytokeratin 20.

    nuclei are the best candidates to study collective properties of low-lying states since these
    nuclei are quite well studied experimentally. Phenomenological model is used to evaluate the positive-parity states energy spectra and the structure of these nuclei by taking into account the Coriolis mixing between states. Deviations from the adiabatic conditions are found to be occurred.

    In this paper, we report a compact and ultra-wide band antenna on a flexible substrate using the 5-(4-(perfluorohexyl)phenyl)thiophene-2-carbaldehyde compound for microwave imaging. In contrast to other microwave based imaging systems, such as an array of 16 antennas, we proposed a bi-static radar based imaging system consisting of two omnidirectional antennas, which reduces complexity and the overall dimension. The proposed compact antennas are 20 × 14 mm2 and designed for operating at frequencies from 4 to 6 GHz. To allow for implantation into a bra, the electromagnetic performances of the antennas must be considered in bending conditions. In comparison with the recently reported flexible antennas, we demonstrated both electromagnetic performance and imaging reconstruction for bending conditions. For the proof of concept, the electromagnetic performances both at flat and bending conditions have been verified using a homogeneous multilayer model of the human breast phantom. Our results demonstrate that the antenna, even at bending conditions, exhibits an excellent omni-directional radiation pattern with an average efficiency above 70% and average gain above 1 dBi, within the operational frequency band. The comprehensive aim of the realized antenna is to design a biodegradable and wearable antenna-based bra for early breast cancer detection in the future.

    The morphology of the adult male of Drosichoides ?haematoptera (Cockerell) is redescribed and illustrated and the adult female of Buchnericoccus sp. (Hemiptera: Monophlebidae) is also described and illustrated. These male and female specimens perhaps are conspecific. Genus Buchericoccus Reyne may be a junior synonym of genus Drosichoides Morrison.

    1. Using ordinary clinical thermometers resting oral temperatures were taken in 4,463 schoolgirls between the ages of 6 and 20 years. 2. From 2,500 readings in clinically healthy and apyrexial girls charts were made to show temperature variations. 3. It was demonstrated that in the age group 6-10 the mean temperature was 99.5 F. That in the age group 10-14 the mean temperature was 99.3 F and in the age group 14-20 the mean temperature was 99.1 F. 4. For all age groups the majority fell within the limit of 98.9 – 100 F. 5. It is not uncommon to encounter a temperature of over 100º and up to 100.8º of no pathological significance. 6. Temperature readings are not a reliable guide in the clinical assessment of children unless the above considerations are borne in mind.

    Catamenial pneumothorax is a rare condition. We report a case of a 36-year-old female who presented with dyspnoea every time before she had her regular menses. Further investigation confirmed that she had catamenial pneumothorax. With this case we wish to highlight this rare diagnostic entity that every clinician should keep in mind.

    Megasybacodes brevitarsis Kakizoe, Maruyama Masumoto, a new genus and new species of the tribe Rhyparini, is described based on a single female from Borneo. It is allied to the genus Sybacodes Fairmaire, 1896, but easily distinguished by its short protarsi, broad flattened basal tarsomeres of the meso- and metatarsi, broad flattened tibiae, and wrinkled pronotal and elytral surfaces. Checklist of rhyparine species from Borneo is also provided.

    CT scanning deliver much higher radiation doses than planar radiological procedures, which puts patients to high risks. This study measures and evaluates patient doses during chest and abdomen computed tomography procedures. Particular attention is given to measuring the dose to the equivalent breast (mSv) and to estimate the associated risks of breast cancer to young female patients (15-35 years). Data was obtained from standard examinations from three hospitals. The measured values of CT dose indexes, CTDI (mGy) as well as exposure-related parameters were used for assessment. Breast and effective doses were extrapolated using a software. The results showed remarkable variations of the mean organ equivalent doses for similar CT examinations in the studied hospitals. This could be attributed to the variation in CT scanning imaging technique, and clinical indications. The average effective dose to the chest was 7.9 mSv (2.3-47.0 mSv) and for the abdomen the mean dose was 6.6 mSv, ranging from (3.3-27 mSv). The breast received equivalent doses from chest and abdomen procedures as follows: 10.2 (1.6-33 mSv) and 10.1(2.3-19 mS) Sv respectively. Each procedure yielded high risks of breast cancer for young females. Implementation of accurate referral criteria is recommended to avoid unnecessary breast radiation exposure.
