Ocular and brain imaging findings in Peters\u27 anomaly: A case report and literature review

Peters\u27 anomaly is a rare congenital eye condition characterized by anterior segment dysgenesis and commonly presents as unilateral or bilateral corneal opacity in the early neonatal period. Peters\u27 anomaly is often associated with congenital brain and skull abnormalities, which are frequently overlooked. In this paper, we present a case of a 5-day-old female neonate with Peters\u27 anomaly, and review the literature for similar reports that describe associated brain imaging findings. In our case, imaging studies show abnormalities involving the anterior segments of both globes with absent intracranial manifestations. Although Peters\u27 anomaly is a condition of interest for ophthalmologists, radiological studies should be performed, and neuroradiologists should be aware of the imaging findings associated with this rare entity

Understanding organization-customer links in a service setting in Russia

This study examines the effect of management commitment to service quality on customer satisfaction through the mediating links of service climate and core and relational service performance in a high-power distance culture. Data were collected using a survey distributed to the FLEs and customers of branches of a Russian retail bank. Study findings demonstrate that branch service climate mediates the management commitment to service quality – service performance relationship and that this indirect effect is stronger on core service performance relative to relational service performance. Contrary to expectations, our findings demonstrate the importance of relational service performance relative to core service performance as a mediator of the branch service climate – branch customer satisfaction relationship. Implications of these novel findings and future research directions are discussed

Experimental study of multi-pass solar air thermal collector system assisted with sensible energy-storing matrix

Analysis of heat transfer around the components of multi-pass solar air heating collector and its per�formance enhancement has been presented using experimental approach. Radiation and convection heat transfer from the system covers and collector plate to the flowing airstreams in the collector system have been investigated. Geological porous matrix has been used as thermal energy reservoir. Test rig was set up under daily average solar insolation, ambient temperature, wind speed, and relative humidity of 302.40 Wm-2, 29.30 �C, 0.58 ms�1 , and 48.53%, respectively. Thermal performance evaluation of the multi-pass solar air collector has been conducted in accordance with the ASHRAE standard specified for the solar air heating systems. Thermal collector efficiency range of 51.91e72.55% has been achieved with an optimum air mass flow rate of 0.013 kgs�1 . System evaporative capacity range of 1:158 � 10�3 - 1:205 � 10�3 kgs�1 was computed. The matrix has extended the span of system operation for more than 3 h after sunset. Comparison of the outcome of multi-pass solar collector performance with the reported study has been done with good agreement. However, an improvement in performance through heat transfer from collector to the flowing air could be achieved

New Media and Crisis Management in Jordan: COVID 19 Perspective

The study aimed at identifying the relationship between the most effective digital media in managing the Corona crisis in Jordan; and the contribution of digital media in managing the (Covid 19) crisis. To achieve the aims of the study, the researcher adopted the quantitative survey method using an electronic questionnaire designed to collect data. It was distributed to an intentional sample of 50 employees (males and females) from the communication and media staff in the Jordanian government institutions. The study concluded that the most effective digital communication technologies in managing the Corona crisis were press conferences (media briefings), press coverage through digital platforms, electronic news, video reports and community initiatives through social media platforms. The results also showed that digital media contributed to managing the Corona crisis in Jordan by relying on effective and organized digital crisis communication, which helped to coordinate efforts with the relevant health and security authorities in the country about the disease developments and the decisions related, besides the immediate responses to inquiries and questions of reviewers and callers about preventive health procedures and measures of safety from the Corona virus. In light of these results, the study recommended that media briefings in crises through digital media should be adopted due to their effectiveness in managing health crises facing countries, as one of the most effective methods of digital communication technologies

Acetone-Gasoline Blend as an Alternative Fuel in SI Engines: A Novel Comparison of Performance, Emission, and Lube Oil Degradation

The disproportionate use of petroleum products and stringent exhaust emissions has emphasized the need for alternative green fuels. Although several studies have been conducted to ascertain the performance of acetone-gasoline blends in spark-ignition (SI) engines, limited work has been done to determine the influence of fuel on lubricant oil deterioration. The current study fills the gap through lubricant oil testing by running the engine for 120 h on pure gasoline (G) and gasoline with 10% by volume acetone (A10). Compared to gasoline, A10 produced better results in 11.74 and 12.05% higher brake power (BP) and brake thermal efficiency (BTE), respectively, at a 6.72% lower brake-specific fuel consumption (BSFC). The blended fuel A10 produced 56.54, 33.67, and 50% lower CO, CO2, and HC emissions. However, gasoline remained competitive due to lower oil deterioration than A10. The flash-point and kinematic viscosity, compared to fresh oil, decreased by 19.63 and 27.43% for G and 15.73 and 20.57% for A10, respectively. Similarly, G and A10 showed a decrease in total base number (TBN) by 17.98 and 31.46%, respectively. However, A10 is more detrimental to lubricating oil due to a 12, 5, 15, and 30% increase in metallic particles like aluminum, chromium, copper, and iron, respectively, compared to fresh oil. Performance additives like calcium and phosphorous in lubricant oil for A10 decreased by 10.04 and 4.04% in comparison to gasoline, respectively. The concentration of zinc was found to be 18.78% higher in A10 when compared with gasoline. A higher proportion of water molecules and metal particles were found in lubricant oil for A10

Carbon Dioxide Removal Using Blended Amine Solution in a Randomly Packed Bed Column

  Many researchers are currently investigating carbon dioxide capture and storage since it is suppressing the global warming phenomenon. Aqueous carbon dioxide chemical absorption is the most effective method. The present study incorporates the applicability and performance of blended alkanol amine solutions monoethanolamine (MEA) with diethylenetriamine (DETA) as a chemical blended absorbent investigated in a pilot scale column packed randomly with Rashing rings. The effect of operating conditions on absorption performance was examined. The performance investigation is given in terms of the overall mass transfer coefficient  and carbon dioxide capture efficiency (ƞ). Typically, DETA: MEA with a mass ratio of 1:1 and total mass concentration of 30 % wt.  could provide the highest KGav with a value of 0.1572 (kmol/(m3*Kpa*hr)) and ƞ with a value of 98.79 %. While at the same condition in terms of liquid and gas rate, with DETA: MEA in the blending mass ratio 0.25:1, the KGav and ƞ values equal to: 0.1198 (kmol/(m3*Kpa*hr)) and 96.37%, respectively. Based on these findings, it is reasonable to assume that diethylenetriamine, a solution of alkanol amines, would serve as an efficient blending absorbent for carbon dioxide removal

In situ readout of DNA barcodes and single base edits facilitated by in vitro transcription

Molecular barcoding technologies that uniquely identify single cells are hampered by limitations in barcode measurement. Readout by sequencing does not preserve the spatial organization of cells in tissues, whereas imaging methods preserve spatial structure but are less sensitive to barcode sequence. Here we introduce a system for image-based readout of short (20-base-pair) DNA barcodes. In this system, called Zombie, phage RNA polymerases transcribe engineered barcodes in fixed cells. The resulting RNA is subsequently detected by fluorescent in situ hybridization. Using competing match and mismatch probes, Zombie can accurately discriminate single-nucleotide differences in the barcodes. This method allows in situ readout of dense combinatorial barcode libraries and single-base mutations produced by CRISPR base editors without requiring barcode expression in live cells. Zombie functions across diverse contexts, including cell culture, chick embryos and adult mouse brain tissue. The ability to sensitively read out compact and diverse DNA barcodes by imaging will facilitate a broad range of barcoding and genomic recording strategies
