Background: Inguinal hernia repair is one of the most commonly performed surgical procedures. Regional blocks might provide excellent analgesia and reduce complications in the postoperative period. We aimed to compare the postoperative analgesic effect of the ultrasound-guided transversalis fascia (TF) plane block versus the transmuscular quadratus lumborum (QL) block in patients undergoing unilateral inguinal hernia repair. Methods: Fifty patients enrolled in this comparative study and were randomly assigned into two equal groups. One group received an ultrasound-guided QL block. In comparison, the other group received an ultrasound-guided TF plane block. The primary outcome was the patient-assessed resting, and movement-induced pain on the numeric pain rating scale (NRS) measured at 30 minutes postoperatively. Secondary outcomes included the percentage of patients receiving rescue analgesia in the first postoperative day, ease of performance of the technique, and incidence of adverse effects. Results: There were no statistically significant differences in NRS at rest and with movement between the groups over the first 24 hours postoperatively. The proportion of patients that received postoperative rescue analgesics during the first 30 minutes postoperatively was 4% (n = 1) in the QL group compared to 12% (n = 3) in the TF group. However, the mean performance time of the TF block was shorter than that of the QL block, and the performance of the TF block appeared easier technically. Conclusions: The ultrasound-guided TF plane block could be as effective as the QL block in lowering pain scores and decreasing opioid consumption following nonrecurrent inguinal herniorrhaphy.
Magnetic Design and Field Optimization of a Superferric Dipole for the RISP Fragment Separator

The in-flight fragment separator of the Rare Isotope Science Project requires eight dipole magnets to produce a gap field of 1.7 T in a deflection sector of 30 degree with a 6-m central radius. If the beam-optics requirements are to be met, an integral field homogeneity of a few units (1 unit = 10−4) must be achieved. A superferric dipole magnet has been designed by using the Low-Temperature Superconducting wire NbTi and soft iron of grade SAE1010. The 3D magnetic design and field optimization have been performed using the Opera code. The length and the width of the air slots in the poles have been determined in an optimization process that considered not only the uniformity of the field in the straight section but also the field errors in the end regions. The field uniformity has also been studied for a range of operation of the dipole magnet from 0.4 T to 1.7 T. The magnetic design and field uniformity are discussed.

Voyage data recorders (VDR) enable accident investigators to review procedures and instructions before an incident and help to identify the cause of any accident. The Future data recording should be capable of recording data audio and video during day and night. The recording should be of high integrity, digital as well as independent of ship supplies. Voyage data recorder, popular name black- box, is used for recording all kinds of navigation information. VDR is a data recording system designed for all vessels required to comply with the International Maritime Organization IMO"s and International Convention safety of life at sea SOLAS requirements (IMO). Data from various sensors on board the vessel is collected, digitized, compressed and then stored in an externally mounted protective storage unit. The protective storage unit is a tamper-proof unit designed to with stand the extreme shock impact, pressure and heat, which could be associated with a marine incident (fire, explosion, collision, sinking, etc). This research realizes the importance of obtaining these stored data for accident analysis. This paper considers a real case accident, by downloading and replaying the data of real black box for a sunken ship in the red sea. Eventually, video recorded data of the accident will be more helpful to the investigation.

In this current study, the electrophoretic deposition (EPD) process of polyaniline (PANI) is reported kineticallyvia the use of response surface methodology (RSM) with a focus on the three models of kinetics;Hamaker, Zhang, and Baldisseri using both statistical and quantitative techniques. The particles of formicacid and acetonitrile-based suspensions as a result of the electrostatic interaction were evaluated usingparticle size and zeta potential analyses. The fundamentals of PANI-EPD kinetics were used to demonstratethe influence of the EPD parameters on the properties of the deposited films over an interval of180–600 s. The cathodic reduction during PANI-EPD simultaneously, the entanglement process and thecontrol of the kinetics was once reported. Therefore, low voltages were used to avoid significant lossof PANI, which decreases during the EPD process, initiated by physicochemical characterization (SEM,FT-IR and XRD). The effect of deposition time and deposition voltage on PANI-EPD kinetics at intervals(180–600 s) was quantified by RSM. Accordingly, the result obtained obeyed a linear growth law consistentwith Hamaker’s’ law. For comparison, optical absorbance and profilometry provide an approximationof PANI’s deposition rate, extinction coefficient, and density. Again, the Baldisseri model was ableto reproduce experimental data well alongside some other semi-empirical equations of kinetics. Thestudy is very significant in terms of the process through which thermal degradation occurs and as a resultused this to anticipate the thermal stability of a process, thereby avoiding thermal degradation of polymerproducts as an industrial application.

The volatile oils obtained from the leaves of four pecan cultivars growing in Egypt were evaluated for their chemical composition and antimicrobial activity. The selected cultivars (cv.) were Carya illinoinensis (Wangneh.) K. Koch. cv. Wichita, C. illinoinensis cv. Western Schley, C. illinoinensis cv. Cherokee, and C. illinoinensis cv. Sioux. The gas chromatography-mass spectrometry analyses revealed that the volatile oils from samples of the different cultivars differ in composition and percentage of their components. b-Curcumene was found as the major constituent of the cv.Wichita oil, whereas germacrene D was the major component of cv. Sioux, cv. Cherokee, and cv. Western Schley. The antimicrobial activity was assayed using the Kirby-Bauer Method by measuring the zone of inhibition of growth. All volatile oils displayed an antimicrobial activity against the tested bacterial strains. On the other hand, only the volatile oil of cv. Wichita showed an antifungal effect on Aspergillus flavus. This work has identified candidates of volatile oils for future in vivo studies to develop antibiotic substitutes for the diminution of human and animal pathogenic bacteria. Nevertheless, the variations of the volatile oil components and antimicrobial potencies of the different studied cultivars, necessitate identifying the cultivars used in future studies.
