Authors: El-Eishy Mohamed Magdy , Abdelalim Galal Mohamed , Aboul-Fotouh Tarek Mohammad 
Published: September 2023

AbstractThis research paper examined the operational performance and greenhouse gas (GHG) emissions of an existing gas treatment plant. Extensive data collection and analysis were undertaken to assess energy consumption and emissions and identify major emitter units. A GHG emission inventory was developed, and a benchmarking analysis was conducted. The gap analysis revealed excessive emissions, leading to the identification of potential GHG abatement alternatives for the turbo compressor and stabilizer heater. Technical feasibility assessments and economic evaluations were performed for the implementation of waste heat recovery systems, specifically an absorption chiller and a hot oil-driven re-boiler. The results demonstrated significant energy savings, emission reduction, and positive financial returns. The economic evaluation of the abatement opportunities revealed an estimated annual savings of $229,287 US with a simple payback period (SPBP) of 2.96 years and an internal rate of return (IRR) of 32%/year for the absorption chiller. The re-boiler heat system showed an estimated annual savings of $209,456 US with an SPBP of 5.14 years and an IRR of 14%/year. The total investment for both opportunities amounted to $1,755,773 US, with a total annual savings of $438,743 US. The combined SPBP for the opportunities was 4 years, with an IRR of 21%/year. Sensitivity analyses demonstrated the absorption chiller’s financial viability, while the hot oil-driven re-boiler opportunity proved more sensitive to variations in investment costs and savings. Therefore, it is recommended to implement both opportunities together.
Hypercalcemia of Malignancy Complicated by Osteonecrosis of the Jaw Treated With Cinacalcet
Authors: Vasquez Libia , Cortes Tiffany 
Published: September 2023

Abstract
Hypercalcemia of malignancy (HCM) is a common complication seen in patients with cancer and is associated with high morbidity and mortality. Current long-term medical therapy for HCM focuses on inhibiting bone resorption with bisphosphonates or denosumab, which have the rare complication of osteonecrosis of the jaw. This case illustrates cinacalcet as an effective therapy for severe HCM resulting from PTH-related peptide in the setting of osteonecrosis of the jaw. Although the mechanism of action remains unclear, cinacalcet has been successful in other HCM cases even if not associated with elevated PTH-related peptide.
Acquisition of Interleukin-6 Production Ability Over Time With Pheochromocytoma
Authors: Toyoda Yohei , Aiga Ko , Kometani Mitsuhiro , Yoneda Takashi 
Published: September 2023

Abstract
Pheochromocytoma is a tumor of chromaffin cells causing catecholamines overproduction. Interleukin-6 (IL-6), a cytokine, is central to inflammation and immunity. Few studies have reported IL-6–producing pheochromocytoma whose underlying mechanism has not been elucidated. Herein, we present a case of pheochromocytoma whose clinical manifestations changed, and IL-6 levels elevated over time. A 48-year-old woman was referred to our hospital for fever and hepatic dysfunction. Six years prior, a right adrenal tumor was detected during the examination for ovarian teratoma without C-reactive protein (CRP) elevation. Several imaging studies at our hospital showed no abnormalities except for an increase in the size of the adrenal tumor and hepatomegaly. In addition, antibiotics did not improve the fever. Laboratory tests showed elevated levels of CRP with IL-6 elevation. An enlarged adrenal tumor was detected. Administering doxazosin lowered the CRP and IL-6 levels, then IL-6–producing pheochromocytoma was suspected, and adrenalectomy was performed. After surgery, fever and hepatic function were improved, and the CRP and IL-6 levels were normalized. Immunostaining of the resected tissue showed IL-6 focal positivity, which meant the phenotype of tumor cells focally changed their phenotypes over time. IL-6–producing pheochromocytoma should be considered in patients with adrenal tumors and fever of unknown origin.
Improving and analysing the spectral access performance of QAM-64 optical NOMA using a hybrid ED-CSD algorithm
Authors: Kumar Arun , Gaur Nishant , Chakravarti Sumit 
Published: September 2023

Abstract
Cognitive radio (Cr) is one of among the most promising developments, which combines optical non-orthogonal multiple access (O-NOMA) methods to increase the fifth generation (5G) spectrum’s usage efficiency. In this work, we provide a hybrid approach based on cyclic stationary feature detection (CFD) and energy detection (ED). The probability of false alarm (PFA), on which it is based, is used to choose which spectrum sensing (SS) approach to use. When PFA is less than 0.5, the ED is chosen; otherwise, the MF is. The suggested detection method in O-NOMA is investigated using Matlab-2016 simulation with reference to several metrics, such as bit error rate (BER), signal-to-noise ratio (SNR), probability of detection (PD), and PFA.

Abstract

Objectives
We aimed to assess the efficacy of oral use of oral desamino-D-arginine-8-vasopressin lyophilisate (OLD) in children with central diabetes insipidus (CDI).

Methods
Clinical, laboratory, and imaging characteristics of twenty-five children with CDI treated with OLD were evaluated.

Results
Fourteen boys and eleven girls with a mean age of 52.37 months were evaluated. These children (mean weight and height at admission, 26.81 ± 14.8 kg vs. 92.52 ± 30 cm) presented with failure to thrive, irritability, prolonged fever, polyuria and hypernatremia (mean sodium level, 143.12 ± 8.6 mEq/L). At the time of hypernatremia, mean serum and urine osmolality were 298.2 ± 18 mOsm/kg and 160.20 ± 8.7 mOsm/kg, respectively. ADH levels were undetectable (<0.5 pmol/L) at admission in all cases. Oral administration of desmopressin lyophilisate (120 µg/tablet) was initiated at a dose of 5 μg/kg/day in two divided doses together with controlled water intake to avoid hyponatremia. Serum sodium levels normalised in a mean duration of 15.2 ± 16.4 h with a mean decline rate of 0.12 ± 0.04 mEq/L/h. Nine children needed rehospitalization because of hypernatremia due to non-compliance. Four episode of hyponatremia was observed. Weight gain and growth were normal during the mean follow-up duration of 37.79 ± 48.2 months.

Conclusions
Administration of OLD was practical and safe in the treatment of CDI in children with CNS malformations in this small retrospective series.

Great potentials of lignin-based separator for Li-ion battery with electrospinning in aqueous system
Authors: Zhang Weipan , Hao Pengfei , Lei Lirong , Hou Yi 
Published: September 2023

Abstract
Separator plays a key role in the safety and performances of lithium-ion batteries with the needs of good thermal stability and wettability. Compared with the commercial separator mainly made by polyolefins in organic solvents, the electrospinning of lignin/polyvinyl alcohol in an aqueous solution has been investigated as a green and economically viable method to produce high-performance separators without any other chemical additives. Lignin/polyvinyl alcohol (mass ratio: 3:7) nanofiber separators outperform commercial polypropylene separators in terms of porosity (71 %), liquid absorption (373 %), and outstanding thermal stability at 200 °C. Additionally, Li-ion battery cells that were constructed using different separators were assessed to demonstrate favorable electrochemical performance. The results showed that fabricated Li-ion battery with Lignin/polyvinyl alcohol (mass ratio: 3:7) nanofiber separators possesses a superior capacitance of 154.1 mA h g−1 at 0.5 C, and maintained outstanding cycle stability after 50 times of charging and discharging process at 0.5 C with the capacitance retention rate up to 98.7 %. The facile and sustainable synthesis strategy of lignin-based separator materials for Li-ion batteries developed in this work provides new perspectives for related research, especially based on environmentally friendly aqueous systems.
Failure criteria and microstructure evolution mechanism of the alkali–silica reaction of concrete
Authors: Wang Yongbo , Gao Peng , Su Huaizhi , Qin Yuanyu , Wang Yimeng , Xue Gang 
Published: September 2023

Abstract
In this study, the influence of two distinct reactive aggregate dosages on the alkali–silica reaction (ASR) of concrete was investigated. The expansion ratio, axial compressive strength, splitting tensile strength, and relative dynamic elastic modulus (RDEM) of concrete were considered as the main parameters to study the failure criteria of concrete induced by ASR at 40°C. Microscopic experiments, such as scanning electron microscopy and X-ray computed microtomography, were applied to analyze the damage induced by ASR on the concrete prisms and the propagation of internal cracks of the reactive aggregates in nanospace. The results showed that the two ranges can be used as the failure criteria produced by the ASR of concrete containing 3 and 6% dosages of reactive aggregates at 40°C, respectively, when the RDEM of concrete was reduced to 70‒75% and 85‒90%. Additionally, the results of CT indicated that microcracks tended to extend from the initial defects of aggregate to the cement slurry. Meanwhile, ASR gel packed with the pores, which reduced the porosity. It was noteworthy that the adhesive force between the ASR gel and the cement matrix after filling pores could not make up for the loss of the mechanical properties of concrete.
Influence of tetrabutylammonium bromide based ionic liquid on the aggregation behavior of dodecyltrimethylammonium bromide in the range (293.15 K–313.15 K): acoustic and volumetric investigation
Authors: Hooshyar Hossein , Sadeghi Rahmat 
Published: September 2023

Abstract
The effect of the ionic liquid analogue tetrabutylammonium bromide on the aggregation behaviour of the cationic surfactant dodecyltrimethylammonium bromide in aqueous medium was investigated with volumetric and compressibility measurements over a wide temperature range (293.15–313.15) K. The data obtained were used to obtain density data. Based on the density data obtained, the volumetric properties (apparent molar volumes and partial molar volumes) of the surfactant in unimeric and micellar forms were evaluated and discussed in terms of the respective ionic and dipolar interactions. The data obtained were analysed to determine the effects of (i) temperature and (ii) salt added to the surfactant. The results were also interpreted in terms of the molecular interactions occurring in the binary mixtures of the present study. The addition of tetrabutylammonium bromide has a lowering effect on the CMC values of the surfactant studied in aqueous medium.

Published: September 2023

In recent years, the sustainability literacy has become crucial for building more sustainable future. In this regard, a shift toward sustainability requires literate society on sustainability issues at global scale. Thus, the current study aims to detect the status of sustainability literacy of British and Turkish students. The study was conducted as a survey research with university students in the UK and Turkey within the context of a project that was supported by TUBITAK (Turkish Scientific and Technological Research Organization) and entitled “Ecological literacy education”. The participants (n: 1023) of the study are students attending several departments of Plymouth University in the UK and Mugla Sitki Kocman University in Turkey. The data were collected by using the Scala of Sustainability Literacy and analyzed using appropriate statistical tests at SPSS 22. The findings show that the participants’ sustainability literacy varies significantly depending on their sustainability attitude (SA), sustainability behavior (SB), sustainability knowledge (SK). Besides, the results of t- test analysis indicate that the participants exhibit different tendencies depending on the variables nationality, gender and place. On the other hand, the results of One-way ANOVA-Test revealed that the participants’ sustainability literacy varies depending on the department attended.

Published: September 2023

The present study aimed to obtain good quality croissants from wholegrain wheat flour using baking sourdoughs prepared from single starter cultures of Pediococcus acidilactici 02P108 (PA), Pediococcus pentosaceus SM2D17 (PP) and Enteroccocus durans 09B374 (ED) as an attempt to overcome the usual negative effects of the wholegrain flour on the characteristics of this specific bakery product group. Results showed that the addition of sourdough in the wholegrain wheat dough had similar performance as that of conventional baker’s yeast regarding the rheological characteristics of dough. The dynamic viscosity of all sourdough-leavened samples remained higher than that of the control sample at all tested shear rates. A positive effect of sourdoughs used on the development of baking dough was observed in terms of specific volume improvement, higher degree of softening, and reduced baking loss. However, these positive effects were found as strain-specific. The use of Enteroccocus durans 09B374-made sourdough showed the most distinguished sensory characteristics and the best results regarding croissant staling during storage. The study demonstrated that sourdoughs used in wholemeal wheat croissant dough had positive effect on the quality characteristics and shelf-life of products. However, strain selection proved as of key importance for the successful production of wholemeal wheat croissants.
