Turkey has announced its plan to construct a new waterway, Canal istanbul, parallel to the Bosphorus. in this study,the influence of Canal istanbul on sa.inity distribution in the northern Marmara Sea.is investigated using a previously ca.ibrated 3 D hydrodyna.ic and sa.inity model. Moreover, the sa.inity field of the canal and its propaga.ion are exa.ined based on va.ious meteorological cases. Finally, the flow structure of the canal is determined. it is calculated that at the southern end of the canal, mainly unidirectional flow(from the Black Sea to the Marmara Sea)occurs during 68% of the simula.ion period. A two-layer flow is seen only 28% of the time with a weak lower layer flow, whereas this value decreases to 4% at the north end of the canal. in the southward direction(to the Marmara Sea), velocities higher than 1.5 m/s are rarely observed along the canal. The average surface sa.inity difference in the northern Marmara Sea due to the construction of the canal is calculated to be smaller than 0.50 ppt. The sa.inity difference gradually diminishes as water depth increases and after 25 m(from the surface) almost no difference is observed.

introduction: Upper digestive hemorrhage is one of the main digestive emergencies and remains a major cause of morbidity and morta.ity in Ma.i. The aim of this study was to describe the therapeutic profile and outcome of pa.ients suffering from upper digestive haemorrhage. Methodology: This was a prospective study carried out in the internal medicine department of the Sikasso Regional Hospital from August 2022 to July 2023. All adult pa.ients presenting with upper digestive haemorrhage and ha.ing given their consent, were included. Data were analyzed using SPSS version 21 software. Results: Sixty-three pa.ients were enrolled. The mean age was 49.7 ± 18.99 years, with a male-female sex ra.io of 2.2. Ruptured esophageal va.ices (37.5%) and peptic ulcer (25%) were the main etiologies. Pharmacological treatment was dominated by proton pump inhibitors (85.7%). Hemosta.is endoscopy accounted for 3.17%. The evolution was marked by hemorrha.ic arrest (69.84%), recurrence of hemorrhage (11.11%) and death (19.04%), the main cause of which was hemorrha.ic shock (58.3%). We found no sta.istically significant rela.ionship between prognosis and etiologies (P = 0.11), and length of hospital stay (P = 0.18). Conclusion: Hemosta.is endoscopy remains a challenge for Sikasso Hospital. A holistic strategy of communica.ion and community awareness-raising, combined with adequate technical fa.ilities, will help to improve pa.ient care and outcomes.

Conventional chloromethyla.ion, paraformaldehyde/hydrogen chloride in acetic a.id medium, was applied to 1,2- dimethoxybenzene. Chloroform-soluble poly（3,4-dimethoxy-o-tolylene） was obtained with an intrinsic viscosity of 0.034 dL g^-1. The polymer was evaluated as a condensa.ion redox polymer precursor formed by a Friedel-Crafts reaction. Cleavage of the methoxy groups present in this polymer resulted in poly（3,4-dihydroxy-o-tolylene） which ma.ifested a great air-oxida.ion resistance. The redox property of the latter polymer was found to be 1017 mV by potentiometric titra.ion with 0.05 N ceric ammonium nitrate at 25℃. This midpotential was compared to that of catechol, a monomeric analogue, under the same titra.ion conditions.

This paper presents a swarm intelligence based parameter optimiza.ion of the support vector machine （SVM） for blind image restora.ion. in this work, SVM is used to solve a regression problem. Support vector regression （SVR） has been utilized to obtain a true mapping of images from the observed noisy blurred images. The parameters of SVR are optimized through particle swarm optimiza.ion （PSO） technique. The restora.ion error function has been utilized as the fitness function for PSO. The suggested scheme tries to adapt the SVM parameters depending on the type of blur and noise strength and the experimental results va.idate its effectiveness. The results show that the parameter optimiza.ion of the SVR model gives better performance than conventional SVR model as well as other competent schemes for blind image restora.ion.

Absorption and fluorescence properties of chromophoric dissolved orga.ic matter （CDOM） along a 124 km transect in the Barata.ia Ba.in, a large estuary located in Louisiana, Usa, were investigated during high and low flow periods of the Mississippi River in the spring and winter of 2008-2009. Mean CDOM absorption at 355 nm from the ma.ine to the freshwater end member sta.ions ranged from （3.25 ± 0.56） to （20.76 ± 2.43） m^-1 for the three month high flow period whereas it va.ied from （1.48 ± 1.08） to （25.45 ± 7.03） m^-1 for the same sta.ions during low flow period. Corresponding sa.inity values at these sta.ions indicated the influence of river and shelf exchanges in the lower ba.in and precipita.ion and runoff in the upper ba.in. An inverse rela.ionship of CDOM absorbance and fluorescence with sa.inity observed in the ba.in could he a useful indicator of sa.inity. CDOM fluorescence also va.ied over a large range showing an approximately 8 to 12-fold increase between the ma.ine and freshwater end members for the two flow seasons. Excita.ion-emission matrix spectral plots indicated the presence of va.ious fluorescence components with highest being the A-peak, lowest the T-peak, and the C and M-peaks showing similar trends along the transect. During low flow season the A/C ra.io were well correlated with sta.ion loca.ions indica.ing increased terrestrial influence towards the upper ba.in. CDOM absorption and fluorescence at 355 nm were highly correlated and independent of CDOM sources suggesting that fluorescence could be used to characterize CDOM in the ba.in.
