Published: March 2024

In brief
In silico predictions validated in this study demonstrate the potential for designing shorter equilibration protocols that improve post-warming re-expansion and hatching rates of D7 and D8 in vitro-produced bovine embryos. Our results benefit the livestock industry by providing a refined and reproducible approach to cryopreserving bovine embryos, which, in addition, could be useful for other mammalian species.

Abstract
The cryopreservation of in vitro-produced (IVP) embryos is vital in the cattle industry for genetic selection and crossbreeding programs. Despite its importance, there is no standardized protocol yielding pregnancy rates comparable to fresh embryos. Current approaches often neglect the osmotic tolerance responses to cryoprotectants based on temperature and time. Hereby, we propose improved vitrification methods using shorter dehydration-based protocols. Blastocysts cultured for 7 (D7) or 8 days (D8) were exposed to standard equilibration solution (ES) at 25ºC and 38.5ºC. Optimized exposure times for each temperature and their impact on post-warming re-expansion, hatching rates, cell counts, and apoptosis rate were determined. In silico predictions aligned with in vitro observations, showing original volume recovery within 8 min 30 s at 25ºC or 3 min 40 s at 38.5ºC (D7 blastocysts) and 4 min 25 s at 25ºC and 3 min 15 s at 38.5ºC (D8 blastocysts) after exposure to ES. Vitrification at 38.5ºC resulted in D7 blastocysts re-expansion and hatching rates (93.1% and 38.1%, respectively) comparable to fresh embryos (100.0% and 32.4%, respectively), outperforming the 25ºC protocol (86.2% and 24.4%, respectively; P < 0.05). No differences were observed between D7 and D8 blastocysts using the 38.5ºC protocol. Total cell number was maintained for D7 and D8 blastocysts vitrified at 38.5ºC but decreased at 25ºC (P < 0.05). Apoptosis rates increased post-warming (P < 0.05), except for D8 blastocysts vitrified at 38.5ºC, resembling fresh controls. In conclusion, based on biophysical permeability data, new ES incubation times of 3 min 40 s for D7 blastocysts and 3 min 15 s for D8 blastocysts at 38.5ºC were validated for optimizing vitrification/warming methods for bovine IVP blastocysts.

Published: March 2024

AbstractThis study attempted to optimize pectin extraction from queen pineapple (Qp) peels using microwave-assisted method. A three-factor factorial experimental design was employed to test the interaction of moisture content of pineapple peel, pH of the citric acid solution and extraction time. The three-way interaction among the factors has a significant effect on pectin recovery. Two-way interaction between moisture content and pH level, as well as pH level and extraction time caused significant difference in the pectin recovery. Pectin recovery increases with lower moisture content while longer extraction time does not significantly increase pectin recovery. The optimum combination of the parameters is 12% moisture content, pH level 2 of the citric acid solution, and extraction duration of 2 min, which yielded 1.01 ± 0.01% pectin recovery. This is lower than the results from previous studies on pineapple with 3.88–13.06% pectin recovery using acid extraction method. Hence further optimization is recommended.

Dental caries is a multifactorial disease affects large segment of population worldwide. This study aimed at evaluate the relationship between oral health behaviors including the consumption of sugar/acid diet of both mothers and their children on the caries status of the children. The relationship between the caries status of mothers and children was also evaluated.This cross-sectional study was performed in rural villages near the capital of our country. The dentition status of 57 mother-child pairs was evaluated using World Health Organization (WHO) criteria for oral health surveys. Oral health behaviors and diet assessment of both mothers and children were investigated through WHO suggested questionnaires. Pearson and Spearman correlations, independent sample t-test, and linear regression analysis were used for the statistical analysis. The Significance level was set at 0.05.Mean DMFT values were 16.6 and 1.6 for mothers and children, respectively, whereas children dmft mean value was 4.3. Children of mothers who consumed diet with high sugar and acid content had worse caries status (0.010≤P-value≤0.013). Caries status of children had weak correlation coefficients (0.2-0.4) with mothers’ caries status though statistically significant (0.008≤P-value≥0.048). Linear regression analysis revealed statistically significant models (P&#60;0.05) with R values≤0.2.Although some oral health behaviors and sugar/acid-rich diet of both mothers and their children correlated with the caries status of the children, these correlations were generally weak to intermediate. The current study suggested that oral health behaviors enhancement of both mothers and children could be one of these activities.

Authors: Al-Rubaiee Fadhil Alaywe Atiyah 
Published: March 2024

In the world, salinity has become an increasing danger for agricultural production. A factorial pot experiment using a completely randomized design (CRD) was conducted in the present research, aimed to look at how growth, yield parameters, and biochemical contents were influenced by the exogenous application of calcium chloride (CaCl2, 0, 5, and 10 mM) of tomato exposed to salt stress (NaCl, 0, 25, and 75 mM), Growth was slowed and Both the sodium percentage and proline content increased under salt stress. However, the growth, yield, and biochemical content characteristics were improved by the application of Ca, enhanced plant height, dry weight of the shoots and roots, the number of fruits per plant, fruit weight, the percentage of nitrogen, calcium, magnesium, phosphorus, potassium, relative water content (RWC), and increased proline content, moreover a significant reduction in the sodium percentages, when compared to the control. Lastly, exogenous Ca use improves resistance to salt stress. Moreover, the use of 10 mM CaCl2 caused the beneficial effects of Ca, which has been suggested to enhance tomato performance in salinized conditions.

Published: March 2024

Abstract
The abundance of waste heat generated from gas turbines at oil & gas operations offers a promising avenue for utilizing this thermal energy to desalinate seawater and produce freshwater for various applications using thermal desalination processes. The concept of waste heat recovery is a well-established practice that is currently widely used for the heating of hot oil for purposes such as controlling the quality of the condensate stream. This paper discusses the concept of seawater desalination utilizing waste heat recovery through the thermal desalination process. An assessment of the available waste heat is carried out to evaluate the associated heat capacity for seawater desalination. A block diagram connecting different process units is developed to analyze the integration feasibility of different components involved from feed source (seawater, waste heat) and product (desalinated water or freshwater). Thermal-based desalination technology of multiple effect distillation (MED) is used for the evaluation, and the amount of energy tradeoff is subsequently quantified, based on the scalability of the treated water capacity and potential end use. Process simulation is used to estimate the amount of treated water that can be generated driven by the available waste heat's capacity. Waste heat analysis shows that potentially up to 38 MW of heat can be used for heating the water and used for boiling/distillation to produce the desalinated seawater. This study guides the design strategy and considerations for scaling up the concept of utilizing waste heat recovery from power generation operations for seawater desalination via thermal desalination process. The feasibility of using the freshwater generated either for various uses at oil & gas production facilities or for nearby facilities is also evaluated to achieve energy rationalization and contribute to the decarbonization of oil & gas operations.
Synergistic Application of Superhydrophilic Silanes Coating and Nanobubbles Turbulence to Mitigate Ceramic Nanofiltration Membrane Fouling

Published: March 2024

Abstract
Produced water and wastewater in the petroleum industry often have very high salinity. This incapacitates polymeric flocculants and flotation oil separation. Ceramic nanofiltration (NF) membranes seem like a natural solution for dispersed oils and macromolecules separations at high salinity and temperature. However, membrane fouling limits their application. We showed that by modifying wettability and surface charge and hydration of such membranes and promoting local turbulence one can mitigate membrane fouling.
Based on our past work, we coated ceramic particles with nonionic silane coupling agents with ethylene oxide (CH2-CH2-O)6-9 or EO 9-12 groups. Titania has high surface charge and below isoelectric point attracts negative molecules and droplets. The opposite happens above the isoelectric point. Coating with ethylene oxide silane produced superhydrophilic surface with contact angle below 12 degrees and very low surface energy and zeta potential below +-5 mV. Such surfaces and oil droplets now did during pressure filtration attach in non-touching networks due to steric repulsions and hydration layers, where particles reside in the so called secondary interparticle force minimum that is much shallower. It was easy to clean so coated membranes from adsorbed oils and particles. Application of small nanobubbles with diameter between 50 and 225 nm further promoted turbulence and reduced fouling rate. During nanobubbles collapse, hydroxyl radicals are produced. Such turbulence and oxidative species significantly incapacitated bacteria and no biofouling were observed. Up to 85% reduction of fouling rate was achieved. Pulsed EC fields or radiofrequency RF electromagnetic fields can be used to further reduce nanobubbles’ size.
A Comprehensive Approach for Evaluating and Treating Tight Emulsion

Summery
Although there are numerous research activities done on challenging oil samples to be separated from tight water emulsions, there are still critical elements missing about onsite characterization of the real oil samples with emulsion. This disparity could be the major reason that is leading to limitation towards the design and implementations of better demulsification strategies. Emulsions’ characterization shall inform about its type (water in-crude oil, crude oil-in-water, or multiple), describe surfactants, water cut, droplets size and distribution, and depict the viscosity of the dispersed and continuous phases. Knowledge about the rheological properties of the fluid is vital in engineering design of gathering systems and choose pumps and tubing sizes for wells and pipelines.
In this work, we showed an integrated framework for emulsion characterization and apply that framework in the characterization of real oil samples with tight emulsion. We follow a holistic approach that look at the challenge from downhole in the well to the processing plant. Characterization of the emulsion samples depicts high asphaltenes content (10 wt%), composed of ionizable groups such as carboxylic acid, high water cut, high formation water salinity (&gt; 150, 000 ppm Ca2+ with pH ˜6). Since change in the water cut changes the crude oil, high salinity in the formation water generally leads to very high salt amount per total volume of emulsion (about 2000 ppm Ca2+).
Identification of the major factors leading to tight emulsions through characterization of real oil/water emulsion led us to design better roadmap for demulsification strategies in matured wells. This information is also vital for designing of new wells to accommodate better choices of equipment and process for future highly likely appearance of emulsion.

Abstract
Hydraulic Fracturing is a water intensive operation with utilization of millions of gallons of fresh water in each well stimulation operation. For a sustainable future it is important to conserve fresh water by replacing it with water from alternative resources such as discarded water from NGL plants and seawater. However, utilization of these waters poses significant performance drawbacks due to factors such as water incompatibility with fracturing fluid additives that may lead to formation damage and lowering of well productivity. To overcome these drawbacks new fracturing fluid chemistries, need to be developed that can deliver the optimal well stimulation performance.
In this paper we showcase the development and field applications of two new fracturing fluids that were developed utilizing the discard water for NGL plants and high salinity seawater, respectively. We discuss the excellent performance of these fracturing fluids in enhancing the well productivity and providing a sustainable alternative to fresh water in hydraulic fracturing operations supporting the circular water economy. The new fluid systems were evaluated in several key aspects during laboratory development including, rheology performance and formation damage potential. Extensive compatibility studies were performed with fluids that were the part of operational pumping schedule including main acids and viscoelastic diverters. Further, design of operational programs for successful implementation towards enhancing well productivity in acid fracturing operations will be discussed.
The new fracturing fluids demonstrated excellent high temperature stability, compatibility with acid fracturing fluids and minimal formation damage. The developed fracturing fluids were able to reach a stable viscosity in less than 5 minutes showcasing excellent hydration behavior. Rheological performance tested at 300 °F showed stable viscosity above 300 cP. Because of high salinity of the discard water and seawater the fracturing fluids were developed using a new scale inhibitor. Formation damage tests resulted in high regain permeability of &gt; 85%. Field stimulation treatments in acid fracturing operations using the new discard water from NGL plants as well as seawater based fracturing fluid showcased excellent flowback performance with no reservoir damage. It was shown that the fracturing fluid based on discharged water from the NGL can be utilized in stimulation operations without any pre-treatment of this water whereas, the seawater requires a sulfate removal treatment prior to field application.
New fracturing fluids based on alternative water resources to fresh water were developed and field deployed with excellent productivity enhancement performance. These fracturing fluid systems provide a sustainable alternative to fresh water in addition to supporting the circular water economy.
