Authors: Lara Balasim Al-Dahy  , Basil O. Mohammed  , Saad Dakhil F. Daraji  , Mazin M. Farhan
Published: June 2021

Background: Both benign prostatic hyperplasia (BPH) and prostate cancer (Pca) include prostate enlargement. The second most common cancer among men worldwide is prostate cancer. It has been documented that by the time they reach their 60s, most men will experience benign prostatic hyperplasia. There is a real difficulty differentiating between benign prostatic hyperplasia and prostate cancer, the prostatic specific antigen (PSA) is not used as a reliable marker of prostate cancer. It is a specific biomarker measure specific to prostate tissues and not prostate cancer. Aims In the analysis of the gray zone of tPSA (4-10 ng/ml), add these biochemical markers and differentiate the root cause of prostate tumor in order to minimize painful and intrusive prostate biopsy. Materials and Methods: A cross-sectional and case control study. It included 110 patients ages range (45-81 years) with benign prostatic hyperplasia (n=55) and prostate cancer (n=55). Forty -five apparently healthy subjects were also included as controls. Peripheral blood samples from controls and patients were collected before obtaining a prostatic biopsy from patients. Serum samples were used for measurements of total Prostate Specific Antigen (tPSA), Free Prostate Specific Antigen (fPSA), and Dihydrotestosterone (DHT) by using ELISA technique. Result: Mean (±SD) serum tPSA and fPSA values for Pca were substantially improved compared to both BPH and control (p=0.001 for all), while mean fPSA/tPSA values for PCa were significantly decreased compared to BPH and control values (p=0.001). In PCa, the mean +SD value of the DHT ratios was significantly lower than in each BHP, and controls (P<0.001) were significantly lower in PCa than in each BHP and regulation (P<0.001). The mean DHT values for BPH were significantly higher as compared to control values (p< 0.001). Conclusion: The level of serum tPSA is 4.2 ng/ml for prostate tumor screening, while 10.1 ng/ml for PCa and BPH differentiation.

Intrauterine growth restriction(IUGR) affects about 9% of whole pregnancies.It is known that there is an increased risk of mortality and morbidity in infants.It is a serious disease that causes complications such as acute and chronic pulmonary diseases, necrotizing enterocolitis, intraventricular hemorrhage and retinopathy in the future.We aimed to study the role of oxidized low density lipoprotein (OxLDL), which is an significant risk factor in cardiovascular diseases,in IUGR and its relationship with thiol homeostasis. 38 women with IUGR and 38 healthy pregnant were included in this study.Serum total thiol and native thiol levels were analyzed with fully automatic autoanalysers in patients and controls.Serum OxLDL levels were also measured by ELISA method. According to the results of the study,it was found that OxLDL was significantly higher in the patient group compared to the control group(27.29±3.32 and 10.64±1.05 ng/mL,respectively,p <0.05).However, there was no significant difference between thiol parameters(p> 0.05).In addition, there was a negative correlation between oxLDL and native thiol and OxLDL and total thiol in the IUGR group. Oxidative stress is an important factor in the formation of OxLDL.OxLDL is an effective molecule in all stages of atherosclerosis. It appears that increased oxidative stress in IUGR patients increases OxLDL.Increased OxLDL in pregnancies complicated by IUGR may increase the risk of developing cardiovascular disease for both mother and fetus later in life.Therefore, developing treatment for OxLDL in IUGR patients may protect both mother and child from future dangers.

Published: June 2021

Lead is widely used in various industrial purposes, one of which is in the paint industry. Lead plays an important role in the paint industry which functions as a coloring agent or known as pigment. Lead is a heavy metal whose benefit is unknown in the body. In fact, its existence in the body often causes toxic effects on health. In painting activities, lead can more easily interact and poison paint workers through inhalation, ingestion, and skin. Accute lead poisoning can result in haematological disorders. This study aimed to reveal the level of lead in the air in the painting area and to analyze the differences in lead and hemoglobin levels. This observational study used an analytic cross-sectional design. The study population consisted of 2 groups, namely the study group (exposed group) and the control group (non-exposed group) as a comparison. The research subjects were 20 people consisting of 12 respondents from the exposed group and 8 respondents from the unexposed group.The results of this study indicate that the average exposure to lead levels in the air is0.06834 mg/m3. There was a difference between the lead levels of the exposed group and the unexposed group (sig: 0,00). And there was no difference between the hemoglobin levels of the both groups (sig: 0,349).

Death can occur anywhere, with or without prior treatment by a healthcare professional. A good and complete death registry will meet the information needs. Such a registry will also enhance community safety efforts and policymaking in the health and population sectors. Analysis of risk factors, signs, and symptoms observed before death provides useful information for estimating diseases or causes of death. Verbal autopsy data must be explored in more depth to protect public law and improve health statistics.Methods: This research used observational design. Data obtained from the Health and Demographic Surveillance System of Sleman. Research subjects were all deaths recorded in verbal autopsy document from 2014-2018. Descriptive statistical analysis was used.Results: Differences in the proportion of gender from 2014-2017 were observed, where the number of women was higher than men. Most deaths were above 65 years of age. Most deaths were natural deaths. Unnatural deaths were caused by traffic accidents, drowning, murder, and others, with the most number of cases occurring in 2014 (12%). Indeterminate deaths occurred annually, with the most cases in 2017 (13%). Conclusions: Verbal autopsy has succeeded in distinguishing between natural and unnatural death.

Elm, Lime and Middle Neolithic Cultivation — A Solvable Problem
Authors: Göransson Hans
Published: June 2021

This article is a continuation of my article in CSA 1. It shows how the Alvastra pile-dwelling (4450 B.P. , T 1/2 = 55681 can be dated by means of pollen analysis. The redated Isberga 111 diagram is presented. Low values of elm, lime, and ash are said to reflect the Early Neolithic expansion, while the opposite is said to reveal the Middle Neolithic regression. It is demonstrated that there was no "regression" in western and southern Östergötland, in north-eastern Småland or in southern Scania, when these trees regenerated (the Regeneration Phase starts c. 4550 B.P. and ends c. 3750 B.P. ). The expansion-regression model for the Early and Middle Neolithic is thus no longer valid. The synchronous vegetational changes during the Early and Middle Neolithic are described. Coppice woods with wandering arable fields very likely characterized the Regeneration Phase in many places in southern Sweden.
The Hedeby Coinage

This article deals with the early Nordic pictorial coinage, in all probability struck in Hedeby in the first half of the 9th century. The focus is on the interpretation of its role in societal strategies, since some of the coins reproduce the coins of the Carolingian empire while others expose an iconographic universe of Nordic symbolism. One of these symbols, which is examined somewhat closer, is the ship.
The Odal and its Manifestation in the Landscape
Authors: Zachrisson Torun
Published: June 2021

The concept odal can be regarded in a narrow sense, i.e. as the inherited landed property of a family. But here it is argued that odal should be viewed in a wide sense - as a mentality that is of great importance to the understanding of Late Iron Age society in Sweden. The article focuses on the material expressions which belonging to a family and possessing a farm could take in the individual farmstead in the Mälar Valley. The Viking Age is interpreted as a time period in which there was a need to make the odal visible. The acts of burying dead relatives on top of the graves of early ancestors, erecting runestones, and possibly also erecting mounds are regarded as ways of guarding, marking, and confirming the possession of the odal in the odal man's own eyes and in his neighbours' and consequently also the odal man's position in society.

Modeling a Coronal Mass Ejection from an Extended Filament Channel. I. Eruption and Early Evolution
Authors: Lynch Benjamin J. , Palmerio Erika , DeVore C. Richard , Kazachenko Maria D. , Dahlin Joel T. , Pomoell Jens , Kilpua Emilia K. J.
Published: June 2021

We present observations and modeling of the magnetic field configuration, morphology, and dynamics of a large-scale, high-latitude filament eruption observed by the Solar Dynamics Observatory. We analyze the 2015 July 9–10 filament eruption and the evolution of the resulting coronal mass ejection (CME) through the solar corona. The slow streamer-blowout CME leaves behind an elongated post-eruption arcade above the extended polarity inversion line that is only poorly visible in extreme ultraviolet (EUV) disk observations and does not resemble a typical bright flare-loop system. Magnetohydrodynamic (MHD) simulation results from our data-inspired modeling of this eruption compare favorably with the EUV and white-light coronagraph observations. We estimate the reconnection flux from the simulation’s flare-arcade growth and examine the magnetic-field orientation and evolution of the erupting prominence, highlighting the transition from an erupting sheared-arcade filament channel into a streamer-blowout flux-rope CME. Our results represent the first numerical modeling of a global-scale filament eruption where multiple ambiguous and complex observational signatures in EUV and white light can be fully understood and explained with the MHD simulation. In this context, our findings also suggest that the so-called stealth CME classification, as a driver of unexpected or “problem” geomagnetic storms, belongs more to a continuum of observable/nonobservable signatures than to separate or distinct eruption processes.
Heart Failure and Coronavirus Disease-19
Authors: Hasan Refli
Published: June 2021

Globally, 4.2% population suffer from heart failure. The condition has a mortality rate between 56% and 78%. Coronavirus disease-2019 (COVID-19) was first reported in December 2019 and became a pandemic since March 11, 2020. As COVID-19 emerges, cardiovascular disorders including, heart failure, become one of the most common comorbidity that increase the risk for contracting the disease. Heart failure and COVID-19 have reciprocal relationship. Patients with heart failure are at higher risk for COVID-19 with more unfavorable outcome. COVID-19 itself may deteriorate pre-existing heart failure in the subject. This situation is mediated by the presence of angiotensin converting enzyme-2 (ACE-2) in cardiac myocytes and pericytes, direct effect of viral invasion to myocytes and pericytes, downregulation of ACE-2 which hampers cardiovascular function, and uncontrolled inflammation known as cytokine storm. Prudent management, including implementation of telemedicine, continuation of ACE inhibitor and angiotensin receptor blocker, and medications’ side effects monitoring, is important in managing patients with coexisting heart failure and COVID-19.

Published: June 2021

The experimental work focused on the study of the pharmacological properties of extracts obtained from the Prunus domestica fruits to create a prospective laxative drug with moderate hepatoprotective properties. Prunus domestica fruit extracts have been shown to have a pronounced laxative and moderate hepatoprotective effect. Extract containing fibers at a dose of 200 mg/kg was selected as the most active extract for laxative and hepatoprotective activity among all extracts from the Prunus domestica fruits. It was conventionally named “Prunophyte”. Studies of the specific pharmacological action of “Prunophyte” extract in a model of comorbid functional constipation on the background of combined alcoholic liver disease in rats showed that “Prunophyte” at a dose of 200 mg/kg had positive dynamics in the treatment of constipation on the background of subacute liver disease. In some cases it exceeded the effects of combination therapy with drugs “Silibor” at a dose of 25 mg/kg and “Senadexin” at a dose of 14 mg/kg. “Prunophyte” extract, in contrast to “Senodexin”, did not cause signs of diarrhea in animals, which may be a beneficial feature of this drug in subsequent clinical use. This drug has shown that it can be a promising alternative to a one-time complex treatment with herbal laxatives and hepatoprotectors, which will avoid polypragmatism in the treatment of comorbid conditions in gastroenterology associated with functional constipation and liver dysfunction.

An Improved Denoising of Electrocardiogram Signals Based on Wavelet Thresholding
Authors: Malleswari Pinjala N. , Hima Bindu Ch. , Satya Prasad K.
Published: June 2021

Electrocardiogram (ECG) is the most important signal in the biomedical field for the diagnosis of Cardiac Arrhythmia (CA). ECG signal often interrupted with various noises due to non-stationary nature which leads to poor diagnosis. Denoising process helps the physicians for accurate decision making in treatment. In many papers various noise elimination techniques are tried to enhance the signal quality. In this paper a novel hybrid denoising technique using EMD-DWT for the removal of various noises such as Additive White Gaussian Noise (AWGN), Baseline Wander (BW) noise, Power Line Interference (PLI) noise at various concentrations are compared to the conventional methods in terms of Root Mean Square Error (RSME), Signal to Noise Ratio (SNR), Peak Signal to Noise Ratio (PSNR), Cross-Correlation (CC) and Percent Root Square Difference (PRD). The average values of RMSE, SNR, PSNR, CC and PRD are 0.0890, 9.8821, 14.4464, 0.9872 and 10.9036 for the EMD approach, respectively, and 0.0707, 10.7181, 16.2824, 0.9874 and 10.7245 for the proposed EMD-DWT approach, respectively, by removing AWGN noise. Similarly BW noise and PLI are removed from the ECG signal by calculating the same quality metrics. The proposed methodology has lower RMSE and PRD values, higher SNR, PSNR and CC values than the conventional methods.
Tensile, Compressive and Flexural Behaviours of an Aluminium Hybrid Composite
Authors: Prakash Kumar , Singh Nilamber Kumar
Published: June 2021

Tensile, compressive and flexural (3-point bending) tests are performed on electromechanical universal testing machine (Zwick/Roell 250kN) to determine mechanical characteristics of an aluminium hybrid composite fabricated through stir casting process at different rates of quasi-static loadings in room temperature 25°C. Influence of heat treatment (annealing) is observed on the material properties. After annealing, the tensile, compressive and flexural strengths decrease while ductility, malleability and bending capability of the composite increase. Bending tests are conducted at different crosshead speeds (1-100mm/min) to study its effects on flexural stresses. It is found that the specimen geometry affects the stress-strain behaviour of the composite.

Additive Manufacturing (AM), consists of depositing material in successive layers to obtain the desired part. The parts produced by AM can thus adopt geometries inaccessible by conventional manufacturing means, for example hollow or lattice structures which considerably reduce their weight while keeping or even improving their mechanical properties. Among the many existing processes, Wire Arc Additive Manufacturing (WAAM) is particularly well suited to the manufacture of large metallic parts. It is characterized by a supply of heat in the form of an electric arc (produced by a welding generator) and a supply of material in the form of wire. This paper will discuss the impact of additive manufacturing to enhance the performances of high value components, based on naval application: the manufacturing of a hollow propeller blade demonstrator of 1.5 m high realized in the laboratory.
Post Necking Behaviour and Hardening Characterization of Mild Steel
Authors: Gupta Manish Kumar , Singh Nilamber Kumar
Published: June 2021

This paper investigates the post necking phenomenon in mild steel using six different hardening laws (Hollomon, Swift, Ludwik, Ghosh, Voce and Hockett-Sherby) by extrapolation method. This is carried out through the finite element simulation on tensile deformation of a mild steel specimen under quasi-static condition. Reference flow curves are obtained analytically and found helpful for the numerical simulation. The material parameters of the above hardening laws are evaluated by curve fitting method based on the pre necking experimental data and their suitability is examined before and after necking.
Data-Driven Coral Reef Rehabilitation Using New Biomimicking, Advanced Materials Artificial Reefs
Authors: Higgins Emily , Sobolev Konstantin
Published: June 2021

Abstract Globally, artificial reefs (ARs) are being increasingly used as a coral reef restoration strategy, and ARs made from conventional substrates (e.g. metal, concrete) have had limited success for coral reef conservation due to structure size and lack of pre-deployment
engineering. To curb further deterioration on reefs, technological advances in restoration methods must be quickly tested and applied on a large scale. Here, we present the results of the first IntelliReefs biomimicking “Oceanite” nanotechnology ARs. We compared benthic community
composition on three Oceanite ARs 14 months after deployment in Sint Maarten. We also examined fish abundance, diversity, and behaviour on the ARs. The results from this study suggest that Oceanite can enhance local biodiversity, attract coral recruits, provide food and protection for large
fish communities, and develop a healthy early coral reef community in 14 months. IntelliReefs' future research will focus on large-scale deployments and further development of site-, species-, and function-specific substrates to optimize AR conservation goals and increase project success.
Our Ocean-Shot will deploy durable, bio-enhanced reefs that build resilience to climate change, increase economic benefits, and coastal protection for seaside communities. Oceanite can further be customized for specific stressor mitigation (e.g., pathogens, warming, acidification, reduced
water quality, invasive species).
COBRA: A Research Accelerator for the Crustal Ocean Biosphere
Authors: Huber Julie A. , Orcutt Beth N.
Published: June 2021

Abstract The deep seafloor covers two-thirds of Earth's surface area, but our understanding of the ecosystems and resources found in the deep ocean, as well as the ability of deep-sea ecosystems to withstand human perturbation, is limited. These deep-sea habitats demand urgent
study as there are emergent human uses in the form of deep-sea mining and carbon sequestration that will fundamentally alter physical, chemical, and biological conditions that took millions of years to establish. We propose the international network COBRA, a research accelerator for the crustal
ocean biosphere. COBRA will bring together diverse stakeholders and experts, including interdisciplinary academic and government scientists, private institutions, policy makers, data systems engineers, industry experts, and others to coordinate efforts that generate new knowledge and inform
decision making about activities that could affect the deep ocean and, by extension, all of society. We will also train the next generation of leaders in ocean exploration, science, and policy through an innovative virtual program to carry this effort into future generations of ocean and earth
science research. COBRA will inform policies relating to emergent industrial uses of the deep ocean, decrease the likelihood of serious harm to the environment, and maintain ecosystem services for the benefit of society.

Abstract Marine Life 2030 is a program to establish the globally coordinated system to deliver actionable, transdisciplinary knowledge of ocean life to those who need it, promoting human well-being, sustainable development, and ocean conservation (Figure 1). The diversity
of marine habitats and species is fundamental for human survival. Biodiversity provides opportunities for multiple fisheries, the tourism industry, and harbor medicines and materials. The Marine Biodiversity Observation Network (MBON) is the platform to build the community of practice to implement
Marine Life 2030. MBON fosters collaborations to coordinate collection, sharing, and application of biodiversity information. Benefits of joining MBON include expanded capacity to address research goals, leveraging resources and best practices; linking natural and social sciences to answer
policy questions; engaging diverse and early-career researchers; and addressing issues of concern to humanity.
Boundary Ocean Observation Network for the Global South
Authors: Ordoñez Christopher E , Barth John A. , Roughan Moninya
Published: June 2021

Abstract The UN Decade of Ocean Science for Sustainable Development should establish a Boundary Ocean Observing Network (BOON) for the Global South (GS). The BOON is part of the OceanGlider Program, which is part of the Global Ocean Observing System (GOOS). The BOON is a
network of established timeseries transects collecting long-term data sets. Timeseries are critical for making immediate operational decisions and for identifying long-term trends of anthropogenic global environmental change. The network has proven important enough to continue observations
and expand them. Due to resource and expertise limitations, expanded locations are in similar locations. The UN should build on this success and establish a BOON for the Global South. The same benefits will be garnered by countries and regions that have been missing out. Increased observation
coverage will benefit humanity, improving understanding of the Ocean-Climate System, e.g. leading to improved climate prediction models. The UN will facilitate activities to realize a BOON for the Global South including: coordinating local scientists, partnering scientific and technical experts
with local scientists, identifying new affordable and easy-to-operate technologies, channeling funds for initial and ongoing costs, and building a framework to continue the BOON-GS long after the Ocean Science Decade.
The Estuarine Ecological Knowledge Network: Future Prospects

Published: June 2021

Abstract Estuaries are profoundly rich, diverse, and complex ecosystems, and crucial to the overall health of Earth's oceans. Estuarine ecological complexity is matched by tremendous human cultural diversity. In the United States, millions of people live in estuarine environments
from the Gulf of Mexico to the Arctic—many of whom directly depend on the productivity of marine resources in both commercial and subsistence fishing activities. Yet, estuaries are also among Earth's most threatened landscapes against the backdrop of global warming, sea-level rise, agricultural
and industrial pollution, habitat loss, overfishing, and so on. This represents a looming disaster for our oceans at a global scale. The Estuarine Ecological Knowledge Network (EEKN) is based on the idea that fishing communities living within major estuaries are the key to ensuring the health
of global oceans. Coastal fishing communities have vast accumulations of ecological knowledge about the functioning of estuarine ecosystems and interact with those ecosystems in intimate ways on a daily basis. This network is designed to connect coastal communities in monitoring the health
of estuarine ecosystems and in using traditional ecological knowledge to develop strategies for enhancing ecosystem health and resilience.
The U.S. Ocean Biocode

Abstract Biodiversity is the engine of ocean ecosystems and economies. Efficiently characterizing it, rapidly at high resolution, is the frontier for understanding global change and management. The biggest impediment to breaching that frontier is inadequate DNA reference
libraries, which can currently identify <25% of animal species in environmental profiles. Over the course of the decade, we will build from our existing global network of museums, universities, federal agencies, and the private sector in a broad collaboration to produce the Ocean Biocode,
a well-sampled, voucher-based, open-access reference library of U.S. marine species that will eliminate “dark taxa” (no name or phylogenetic position) from U.S. waters and support a new era in high-resolution oceanography and environmental science founded on accurate environmental
DNA sampling. We need not sequence every species; a strategic, empirically guided inventory will fill key gaps by focusing BioBlitz efforts at one focal site in each marine ecoregion of the U.S. EEZ, targeting taxa missing from regional libraries, coupled with genome skimming, to create reference
libraries of whole mtDNA and nuclear ribosomal cluster. This Ocean Biocode moves beyond the barcode to allow design of targeted probes for non-amplicon species detection, yielding species-level information to stakeholders and enabling future technologies.
An Ocean Science Education Network for the Decade

Published: June 2021

Abstract Ocean science education and ocean literacy are overarching components of all Ocean Decade challenges. Educating the next generation of ocean scientists will help achieve Ocean Decade objectives, while increasing public ocean literacy will motivate citizens to engage
in the ocean science enterprise. During the UN Ocean Decade, a coordinated flow of information among scientists, educators, policy makers, business leaders, and the public will help guide research priorities in addition to enhancing citizens' ocean literacy. Ocean literacy is about more than
the acquisition of ocean science knowledge. It also relates to critical needs for citizens to become responsible in sustainably using the ocean and its resources. Society must gain scientific understanding of the ocean's responses to pressures and make management decisions that are fundamental
for sustainable development of its resources. U.S. ocean science education, outreach, and communication initiatives have been greatly expanded since 2002 due to the work of the National Science Foundation-funded, national Centers for Ocean Sciences Education Excellence (COSEE; now the Consortium
for Ocean Science Exploration and Engagement) network. The infrastructure established by COSEE is well-poised to take on the establishment of a network of networks to forge U.S. leadership in robust international collaborations in support of Ocean Decade objectives.
