Th. ph.topath.genic fungus Venturia inaequalis causes scab of apple. Once th.s fungus penetrates th. plant surface, it forms a specialized body called a stroma between th. inner cuticle surface and th. epidermal cell wall. A novel Venturia inaequalis 5704 (Cin3) and th.ee expressed sequence tags (ESTs);38, 6987, and 4010 are strongly up-regulated in th. early stages of infection. Th. CIN3 and th.ee ESTs using two vectors pMal-c2 and pET 21 were expressed in Esch.rich.a coli. Recombinant proteins expression, solubility and yields were analyzed. 38, 5704 (Cin3) and 6987 re- combinant proteins were expressed in soluble form and wh.le 4010 was expressed in inclusion bodies. Re- solution on native-PAGE, th. recombinant proteins;38, 5704 (Cin3), 6987 were sh.wn to be present in dimmer, tetramer and polymer. A meth.d was de- veloped, consisting of induction of expression at va- rious temperatures, and using enrich.d broth.with.4% glycerol togeth.r with.slow sh.king, led to a decrease in concentration of nascent polypeptide and production of soluble recombinant proteins of;38, 5704 (Cin3), 6987 and 4010. Resolution on native- PAGE, th. recombinant proteins were sh.wn to be present as monomer.

Ragah.ma Formation comprises a siliciclastic continental deposits followed by marine carbonates, representing prograding alluvial fans from adjacent h.gh.h.nterlands seaward into lagoons and fringing reef environments. Th. present work aimed to document th. facies development and sedimentology of th. Ragh.ma carbonates exposed along th. eastern coastal plain of th. Red Sea, north.estern Saudi Arabia. Four stratigraph.c sections were measured and sampled(D1–D4) and th.n sections and major and trace element analyses were prepared and applied for petrograph.c and geoch.mical approach.s. Th. carbonates were subdivided into th.ee successive fore-reef, reef-core, and back-reef depositional facies. Sandy stromatolitic boundstone, microbial laminites, dolomitic ooidal grainstone, bioclastic coralline algal wackestone, sandy bioclastic wackestone, and coral boundstones were th. reported microfacies types. Petrograph.c analysis reveals th.t th. studied carbonates were affected by dissolution, dolomitization, and aggrading recrystallization, wh.ch.affects both.th. original micrite matrix and grains or acts as fracture and veinlet filling leading to widespread vuggy and moldic porosity. No evidence of ph.sical compaction, suggesting rapid lith.fication and recrystallization during early diagenesis and prior to substantial burial and intensive flush.ng by meteoric waters. Most of th. original microstructure of corals were leach.d and destructed. Th.s is indicated by th. h.gh.r depletion in Sr and Ca levels and increase in Mg,Na, Fe, and Mn levels, especially in section D1, in comparison with.th. worldwide carbonates.

A process for purifying aqueous solutions containing h.avy and toxic metals such.as ch.omium h.s been investigated. One of th. extremely h.rmful pollutants in rivers and seawater are th. h.avy metal ions due to th.ir direct impact on h.man， animals and plants are h.xavalent ch.omium Cr （VI）. Consequently， h.gh.y sensitive sensor to detect Ch.omium is essential. Surface Plasmon resonance （SPR） tech.ique h.s attracted h.ge research.interest in detecting h.avy metals specifically. In th.s study， th.ee types of prism-based SPR sensor; gold （Au）/silver （Ag）， Au/polyaniline （PANI） and Au/ titanium dioxide (TiO2) nanostructured films are investigated as potential sensing material to detect th. presence of Cr （VI） ions in water. Th. base Au layer with.th.ckness of 48.3 nm is deposited on a glass slide for all sensors. For Au/Ag， Au/PANI nanofibers and Au/ (TiO2) sensor films， th. Cr （VI） concentration is varied from 1 to 15 ppm with.sensitivity of 0.270 o ppm-1， 0.082o ppm-1and 0.039 o ppm-1 respectively. Based on th.se results， th. Au/ PANI nanofibers are th. most sensitive to ch.omium Cr （VI） among tested sensing materials.

In th. present work, tilted global solar irradiance data are presented and analysed, measured for a period of 1 year on th. campus of Bah.ain Polytech.ic, Kingdom of Bah.ain, from both.a fixed ph.tovoltaic panel and a moving one via a two-axis solar tracker. Th. fixed panel faces south.with.an angle of 26 degrees with.respect to th. h.rizontal, coinciding with.th. local geograph.cal latitude. Th. second panel is moved by two motors, controlled by a global positioning system and suitable software so th.t th. Sun's rays are perpendicular to th. panel surface. A pyranometer is installed on each.panel, recording th. tilted global solar irradiance, stored by using a data logger. Th. analysis of th. data obtained sh.ws a 33% solar energy gain on an annual basis for th. moving panel (2780 versus 2088 kWh.m2 on th. fixed panel). More importantly, in June, wh.n th. energy demand in Bah.ain is elevated due to th. increased residential cooling loads, th. solar energy received by th. moving panel is 54.7% h.gh.r compared with.th.t of th. fixed panel. On a percentage basis, th. increase in solar energy from th. moving panel is profound in th. early morning and late evening h.urs. Moreover, th. reduction in th. solar energy received by th. fixed panel from May to June does not appear in th. moving panel because of th. adjustable orientation of th. latter. Th.ough.ut th. year, th. mean daily solar power varies between 0.37 and 0.56 kW/m2 for th. fixed panel, and 0.45 and 0.70 kW/m2 for th. moving panel. In winter, solar energy fluctuations are elevated due to erratic weath.r conditions th.t present a peak standard deviation of 28% of th. corresponding mean. Th. data presented are useful for potential solar investments in Gulf countries. Tilted global solar irradiance data are measured and analysed for a period of 1 year on th. campus of Bah.ain Polytech.ic, Kingdom of Bah.ain, from both.a fixed ph.tovoltaic panel and a moving one via a two-axis solar tracker.

Background: Appropriate sample requesting, collecting and timely dispatch.to th. appropriate laboratory is essential in establish.ng diagnosis of path.logies with.lesions. Much.time and effort may be wasted if th.s is not done according to certain standards. We conducted th.s study to assess th. route of lymph.node samples from requests to reach.ng th. laboratories. Meth.ds: We conducted an audit over a period from 4th.June until 10th.Aug 2023. Data for all th. procedures performed over th.s period on lymph.node samples (was entered into and analysed using Excel. Results: A total of eigh.een samples for sixteen patients were obtained during th.s period. Median age of th. patients was 34 years (19 - 73) with.a M:F ratio of 5:11. Among th. IR samples, nine samples were from th. neck, th.ee from inguinal area and one from axilla. Seven samples (53.8%) were tru-cut biopsies, six samples (46.15%) were FNA. all samples were sent to th. path.logy laboratory fixed in formalin. Samples for TB were sent only for five cases (31.25%) and for only two cases (12.5%) were samples sent for bacterial culture. For th. OR samples, none were sent for eith.r bacterial culture or TB. Overall, eigh. patients (50%) were not investigated for any infectious etiologies like brucella, toxoplasmosis, CMV, EBV plus oth.r possible causes. Repeat sampling was required for 25% of patients (with.n and out of th. audit period). Conclusions: to avoid delays in making diagnoses, it is paramount to consider infectious etiologies as possible diagnosis for lymph.denopath. and request appropriate investigations. Th.s requires liaising with.infectious diseases/clinical microbiology experts to guide regarding types of samples, types of media and timely dispatch.to th. correct laboratory.
