The study aimed to assess the clinical, laboratory, and blood gas analysis of horses undergoing Marcha training and the effects of voluntary ingestion of hydroelectrolytic and energy replenishers after exercise. Eight horses of both genders aged between 5 and 10 years, were included in the study. The exercise consisted of a 10-min warm-up followed by 45 min uninterrupted Marcha on a flat dirt track in the morning. After exercise, the horses received one of the following treatments: Drinking water (control group);Hydroelectrolytic and energy replenisher containing sodium chloride, potassium chloride, calcium acetate, magnesium chloride, sodium citrate, dextrose, maltodextrin, and sucrose in three different concentrations (Replenishers A, b, and C). The horses were distributed across the four treatments in a 4 × 4 Latin Squares design using a Split-plot system with 48-hr intervals. Clinical and laboratory evaluations were conducted at four time points: T0 - 5 min before exercise;T1 - up to 5 min after exercise;T2 - 2 hr after starting treatment;and T4 - 4 hr after beginning treatment. Concentrations of urea, creatinine, lactate, phosphorus, and ionized calcium significantly changed after exercise. An increase in blood pH and a decrease in chloride concentrations were observed when replenishers b and C were offered after exercise. The replacements were ingested spontaneously by the animals in a volume greater than that of the control group (water). Replacement b was the most ingested by the animals, demonstrating its greatest potential.

One of the most important parameters in meteorology is the mean wind pro fi le in the tropical cyclone boundary layer. The vertical pro fi le of wind speed and wind direction were measured during the period of the nisarga cyclone from May 31st, 2020, to June 5th, 2020, using the newly installed Phased Array Doppler Sodar system at the Center for Space and Atmospheric Science (CSAS), Sanjay Ghodawat University, Kolhapur (16.74 degrees n, 74.37 degrees E; near India ' s western coast). Our analysis revealed that the maximum mean wind speed was 17 m/s on June 3, 2020, at 10:00 IST. It also shows the change in wind direction from southwest to southeast on June 2 and 3, 2020. Daily high-resolution reanalysis data in the domain, 0 - 25 degrees n, 65 - 110 degrees E, during the period from May 31st to June 5th, 2020, revealed the variation of the atmospheric pressure of the nisarga cyclone from 1000 to 1008 hPa, sea surface temperature (SST) between 30 degrees C and 31 degrees C, outgoing longwave radiation (OLR) between 100 and 240 Wm-2 , wind speed between 3 and 15 m/s, and low values of vertical wind shear (VWS) were observed to the north of nisarga track. These observations may provide more insights for the study of boundary layer turbulence during cyclonic activities. (c) 2024 The Shanghai Typhoon Institute of China Meteorological Administration.

Introduction: The birth of a baby is a moment of joy and celebration. However, the neonatal period is a very delicate phase of life. neonatal mortality rates remain high in low-income countries. In Guinea, after 20 years, this rate has fallen from 34.2% in 1998 to 32% in 2018. Objective: To identify the main risk factors for neonatal mortality. Methods: This was an observational, analytical case-control study, lasting 6 months from January 1 to June 30, 2019, conducted at the Institut de nutrition et de la Santé de l’Enfant (InSE) at Donka national Hospital. Results: We collected 242 cases and 242 controls, i.e. a total of 484 records. 748 patients were registered, with 32.35% deaths. 82.86% of deaths occurred in the early neonatal period. Statistical analysis revealed the main risk factors: prematurity (RQ 7.39 95% CI 3.27 - 16.61 p = 0.0000003), hypothermia (RQ 2.29 95% CI 1.51 - 3.46 p = 0.0001), acute fetal distress (RQ 2.13 95% CI 1.33 - 3.43 p = 0.0016), low birth weight (QR 1.91 95% CI 1.12 - 3.24 p = 0.016), home birth (QR 3.26 95% CI 1.25 - 8.46 p = 0.015). Conclusion: neonatal mortality is a health problem in the InSE neonatology department. To reduce the mortality rate in this referral facility, it is essential to equip it and provide ongoing training for staff.

This paper presents a study on COb>2b> atmospheric transformation which was reacted directly with lithium hydroxide solution and metallic lithium. This solution was obtained through the reaction between metallic lithium and deionized water where hydrogen is produced and by exposing the metal at ambient conditions. In the transformation process, atmospheric COb>2b> gas reacts directly with LiOH solution, in both cases, the COb>2b> transformation kinetics was different. For this purpose, reactions between COb>2b> and LiOH solution were carried out under controlled temperature and the second process only with metallic lithium, which was exposed at room temperature, however, in these two processes lithium carbonate oxide was formed and identified. According to the results, the efficiency in COb>2b> transformation is a function of temperature value which was variable until completely obtaining the by-product, its XRD characterization indicated the formation only of Lib>2b>COb>3b> in both procedures. Under laboratory conditions lithium compounds selectively reacted with COb>2b>. In the same way, there is an alternative procedure to obtain LiOH and Lib>2b>COb>3b> for different applications in various areas.
