Influence Of Nanosilica On Solvent Deasphalting For Upgrading Iraqi Heavy Crude Oil, Firdews Shakir, Hussein Q Hussein, Zeinab T Abdulwahhab

Baghdad Science Journal

In this study, the upgrading of Iraqi heavy crude oil was achieved utilizing the solvent deasphalting approach (SDA) and enhanced solvent deasphalting (e-SDA) by adding Nanosilica (NS). The NS was synthesized from local sand. The XRD result, referred to as the amorphous phase, has a wide peak at 2Θ= (22 - 23º) The inclusion of hydrogen-bonded silanol groups (Si–O–H) and siloxane groups (Si–O–Si) in the FTIR spectra. The SDA process was handled using n-pentane solvent at various solvent to oil ratios (SOR) (4-16/1ml/g), room and reflux temperature, and 0.5 h mixing time. In the e-SDA process, various fractions of the …

Reducing The Risk Of Mortality In Chronic Obstructive Pulmonary Disease With Pharmacotherapy: A Narrative Review, Matthew Mintz, Igor Barjaktarevic, Donald A. Mahler, Barry Make, Neil Skolnik, Barbara Yawn, Bree Zeyzus-Johns, Nicola A. Hanania

Abington Jefferson Health Papers

In 2020, chronic obstructive pulmonary disease (COPD) was the fifth leading cause of death in the United States excluding COVID-19, and its mortality burden has been rising since the 1980s. Smoking cessation, long-term oxygen therapy, noninvasive ventilation, and lung volume reduction surgery have had a beneficial effect on mortality; however, until recently, the effects of pharmacologic therapies on all-cause mortality have been unclear. Inhaled pharmacologic treatments for patients with COPD include combinations of long-acting muscarinic receptor antagonists (LAMAs), long-acting-β2-agonists (LABAs), and inhaled corticosteroids (ICS). The recent IMPACT and ETHOS clinical trials reported mortality benefits with ICS/LAMA/LABA triple therapy compared with …

Cryptocurrencies And Climate Change: A Net-Zero Paradox, Jason Maclean

Canadian Journal of Law and Technology

Cryptocurrencies pose a number of complex law and policy problems, the most pressing of which are the industry’s climate and environmental impacts. This article examines the climate and environmental impacts of crypto-assets in the broader law and policy context of the UN Paris Agreement and the global goal of reaching net-zero emissions by 2050 or earlier. This approach not only illuminates the limitations and paradoxical nature of the crypto-industry’s climate commitments, but also the limitations and paradoxical nature of ‘‘net zero” itself as the predominant framing of national, subnational, and nonstate actors’ climate pledges. The article concludes by examining the …

Biotechnology Patent Law Top Ten Of 2021. Experimentation, Blaze Marks, And Unspecified Ranges, Noonan, Kevin E., Torrance, Andrew W.

Santa Clara High Technology Law Journal

Biotechnology has never demonstrated its benefits to society more than in 2021. The SARS-CoV-2 virus that caused the CoVID-19 pandemic met a formidable opponent in mRNA vaccines developed and supplied by Moderna and Pfizer/BioNTech. These vaccines are claimed in myriad – not Myriad – patents and patent applications, many of which are destined to be litigated over the coming years, not least inspired by the many billions of dollars that have been, and will continue to be, earned by their owners. While the world waits for this storm of patent litigation, federal courts continue to be busy with ownership, licensing, …

Estimating The Demand For Groundwater: A Second-Stage Hedonic Land Price Analysis For The Lower Mississippi River Alluvial Plain, Arkansas, Kent Kovacs, Sheby Rider

Agricultural Economics and Agribusiness Faculty Publications and Presentations

We estimate the benefits of the saturated thickness (water-bearing porous material) of the alluvial aquifer in Arkansas through an application of the hedonic price model to the sale of agricultural land. There is evidence from the first-stage analysis of diminishing returns from increasing saturated thickness. Using a survey of farmer operators’ preferences and socioeconomic characteristics, we recover the underlying demand function for saturated thickness in a second-stage analysis. Shifts in the demand function reveal that produced/social capital can be a substitute or a complement to saturated thickness, and human capital is a substitute for saturated thickness.

Combinatorial Identities Associated With A Bivariate Generating Function For Overpartition Pairs, Atul Dixit, Ankush Goswami

School of Mathematical & Statistical Sciences Faculty Publications

We obtain a three-parameter q-series identity that generalizes two results of Chan and Mao. By specializing our identity, we derive new results of combinatorial significance in connection with N(r,s,m,n), a function counting certain overpartition pairs recently introduced by Bringmann, Lovejoy and Osburn. For example, one of our identities gives a closed-form evaluation of a double series in terms of Chebyshev polynomials of the second kind, thereby resulting in an analogue of Euler's pentagonal number theorem. Another of our results expresses a multi-sum involving N(r,s,m,n) in terms of just the partition function p(n). Using a result of Shimura we also relate …

Coloring Complexes And Combinatorial Hopf Monoids, Jacob A. White

School of Mathematical & Statistical Sciences Faculty Publications

We generalize the notion of a coloring complex of a graph to linearized combinatorial Hopf monoids. We determine when a linearized combinatorial Hopf monoid has such a construction, and discover some inequalities that are satisfied by the quasisymmetric function invariants associated to the combinatorial Hopf monoid. We show that the collection of all such coloring complexes forms a linearized combinatorial Hopf monoid, which is the terminal object in the category of combinatorial Hopf monoids with convex characters. We also study several examples of combinatorial Hopf monoids.

Antibacterial Activity Of Three Algal Genera Against Some Pathogenic Bacteria, Janan Jabbar Toma, Farhad Hassan Aziz

Baghdad Science Journal

In the current study, three types of algae namely Tetradesmus nygaardi (MZ801740), Scenedesmus quadricauda (MZ801741) and Coelastrella sp (MZ801742) were extracted by 95% ethanol and hexane against two types of gram positive and two types of gram negative bacteria by wells diffusion methods. Eleven concentrations from the extract of algae (2, 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 mg/ml) were utilized. It was noticed that ethanolic extraction was more effective than hexane in Scenedesmus quadricauda than the two other mentioned algal species against all pathogenic bacteria, Acintobacter baumanii (ATCC: 19606), Klebsiella pneumonia (ATCC: 13883) Enterococcus faecalis …

Retrieving Encrypted Images Using Convolution Neural Network And Fully Homomorphic Encryption, Emad M. Alsaedi, Alaa Kadhim Farhan

Baghdad Science Journal

A content-based image retrieval (CBIR) is a technique used to retrieve images from an image database. However, the CBIR process suffers from less accuracy to retrieve images from an extensive image database and ensure the privacy of images. This paper aims to address the issues of accuracy utilizing deep learning techniques as the CNN method. Also, it provides the necessary privacy for images using fully homomorphic encryption methods by Cheon, Kim, Kim, and Song (CKKS). To achieve these aims, a system has been proposed, namely RCNN_CKKS, that includes two parts. The first part (offline processing) extracts automated high-level features based …
