Oil Prices and the Hydrocarbon Markets
There are two streams of studies that investigate the impact of oil price shocks on the selected hydrocarbon prices. First, the empirical studies that presume, due to the global nature of the crude oil market, the world oil price is an exogenous determining variable to the evolution of the local hydrocarbon markets such as natural gas or natural gas liquids (NGLs). Second, recent empirical studies that have improved our understanding of the source of oil price changes. They treat the real price of oil as an endogenous variable, identify the causes underlying oil price shocks, and then evaluate the impact of structural supply and demand shocks on the other hydrocarbon prices. The first strand of studies does not represent a consensus on the relationship between crude oil and other hydrocarbon prices -- some demonstrate stable and asymmetric relationships and some find no relationship or a very weak relationship. The second strand of studies shows that oil supply-side shocks have a transitory and temporary impact while oil demand-side shocks have a persistent and permanent impact on other hydrocarbon prices. In addition, it shows that the structural shocks in the global crude oil market explain approximately 50% of the variation in the other hydrocarbon markets in the long run.

Sexual Sadism Disorder
Sexual sadism disorder is the condition of experiencing sexual arousal in response to the extreme pain, suffering or humiliation of others. Several other terms have been used to describe the condition, and the condition may overlap with other conditions that involve inflicting pain. It is distinct from situations in which consenting individuals use mild or simulated pain or humiliation for sexual excitement. The words sadism and sadist are derived from Marquis de Sade.

Acute Stress Reaction
Acute stress reaction (also called acute stress disorder, psychological shock, mental shock, or simply shock) is a psychological condition arising in response to a terrifying or traumatic event, or witnessing a traumatic event that induces a strong emotional response within the individual. It should not be confused with the unrelated circulatory condition of shock/hypoperfusion. Acute stress reaction (ASR) may develop into delayed stress reaction (better known as Posttraumatic stress disorder, or PTSD) if stress is not correctly managed. ASR is characterized by re-living and avoiding reminders of an aversive event, as well as generalized hypervigilance after initial exposure to a traumatic event. ASR is differentiated from PTSD as a disorder that precedes it, and if symptoms last for more than one month, it will develop into PTSD. It can thus be thought of as the acute phase of PTSD.

Noninvasive Vagal Nerve Stimulation
Neuromodulation is a promising new area with treatment applications for psychiatry. Electrical stimulation of the vagus nerve is associated with a reduction in peripheral sympathetic and inflammatory function and modulation of brain areas mediating fear and the stress response, and thus has potential applications to patients with stress-related psychiatric disorders, including posttraumatic stress disorder (PTSD) and depression. Non-invasive Vagal Nerve Stimulation (nVNS) can be applied to vagus nerve locations at the neck (transcutaneous cervical, or tcVNS) or ear (transcutaneous auricular, or taVNS), intervening at the level of the underlying psychobiology with potential beneficial treatment effects.

Natural Compounds in Thromboembolism Treatment
Venous thromboembolism (VTE) refers to deep vein thrombosis (DVT), whose consequence may be a pulmonary embolism (PE). Thrombosis is associated with significant morbidity and mortality and is the third most common cardiovascular disease after myocardial infarction and stroke. DVT is associated with the formation of a blood clot in a deep vein in the body. Thrombosis promotes slowed blood flow, hypoxia, cell activation, and the associated release of many active substances involved in blood clot formation. All thrombi which adhere to endothelium consist of fibrin, platelets, and trapped red and white blood cells.

Human Paraoxonase-2 (PON2)
PON1, PON2, and PON3 belong to a family of lactone hydrolyzing enzymes endowed with various substrate specificities. Among PONs, PON2 shows the highest hydrolytic activity toward many acyl-homoserine lactones (acyl-HL) involved in bacterial quorum-sensing signaling. Accordingly, defense against pathogens, such as Brevundimonas aeruginosa (B. aeruginosa), was postulated to be the principal function of PON2. Moreover, findings have highlighted the importance of PON2 in oxidative stress control, inhibition of apoptosis, and the progression of various types of malignancies.

Andrew Jackson Presidential Campaign, 1828
In 1828, Andrew Jackson, who had lost the 1824 election in a runoff in the United States House of Representatives, despite winning both the popular vote and the Electoral vote by significant margins, ran for President of the United States. He had been nominated by the Tennessee state legislature in 1825, and did not face any opposition from Democratic candidates. Jackson launched his campaign on January 8, 1828 with a major speech on the 13th anniversary of the Battle of New Orleans from 1815, thus marking the birth of the modern Democratic Party. Jackson accepted John C. Calhoun, incumbent Vice President under John Quincy Adams, as his running mate. John Quincy Adams was an unpopular President from the beginning of his term, and the Democratic Party, which was just beginning to emerge as a political force, mobilized behind Jackson, a popular war hero who had served in the Battle of New Orleans. Despite his successes as a member of both the House of Representatives and the Senate, as well as the Military Governor of Florida, Jackson had been born in relatively modest surroundings in rural Carolina, which appealed to the majority of Americans, who were small farmers who benefited from the introduction of Universal male suffrage from the 1820s to the 1840s. This expansion of voting rights helped both major political parties (the Democrats and the National Republicans) canvass voters and expand the popular vote. The campaign was marked by large amounts of nasty "mudslinging." Jackson's marriage, for example, came in for vicious attack. When Jackson married his wife Rachel in 1791, the couple believed that she was divorced, however the divorce was not yet finalized, so he had to remarry her once the legal papers were complete. In the Adams campaign's hands, this became a scandal. Charles Hammond, in his Cincinnati Gazette, asked: "Ought a convicted adulteress and her paramour husband be placed in the highest offices of this free and Christian land?" Jackson also came under heavy attack as a slave trader who bought and sold slaves and moved them about in defiance of modern standards or morality. (He was not attacked for merely owning slaves used in plantation work.) The Coffin Handbills attacked Jackson for his courts-martial, execution of deserters and massacres of Indian villages, and also his habit of dueling.

Human Detection Approach for Intrusion in Hazardous Areas
Detecting intrusion in hazardous areas is one of the priorities and duties of safety enhancement. With the emergence of vision intelligence technology, hazardous-area-detection algorithms can support safety managers in predicting potential hazards and making decisions. However, because of the dynamic and complex nature of the jobsite, high-risk zones have a different geometry and can be changed following the schedule and workspace of activity. This leads to hazardous areas being annotated manually.

Single-Coil Eddy Current Sensors
The single-coil eddy current sensors (SCECS) constitute a separate and independent branch among the eddy current sensors. The SCECS sensing element is a single current loop that can be inserted into the measuring zone with harsh and extreme conditions. Such simplicity of the SCECS design ensures sensors’ functioning at high temperatures, reaching 1200 °C and more in gas turbines, high linear speeds of the monitored objects, contamination of the measuring medium by fuel combustion products, vibrations, etc. The main application of the SCECS related to the monitoring the dangerous states of the power plants. The sensors and their cluster compositions make it possible to evaluate a wide range of power plants diagnostic parameters, including radial clearances between the blade tips and the stator of the compressor and turbine of the gas-turbine engine, shaft displacements in the radial thrust bearings, the presence of wear particles of friction pairs in oil system, etc.

Microbiome in Oil Reservoirs
Microorganisms inhabiting subsurface petroleum reservoirs are key players in biochemical transformations. The interactions of microbial communities in these environments are highly complex and still poorly understood. This work aimed to assess publicly available metagenomes from oil reservoirs and implement a robust pipeline of genome-resolved metagenomics to decipher metabolic and taxonomic profiles of petroleum reservoirs worldwide. We noticed that the oil reservoirs with a lower level of intervention were the most similar to the potential functional core, while the oil fields with a long history of water injection had greater variation in functional profile. These results show how key microorganisms and their functions respond to the distinct physicochemical parameters and interventions of the oil field operations such as water injection and expand the knowledge of biogeochemical transformations in these ecosystems.

Treatment Wetlands in Natural Swimming Ponds
Natural swimming ponds using treatment wetlands (TWs) as an element of treatment of swimming water are an ecologically beneficial alternative to conventional pools. Unlike conventional swimming pools, in natural swimming ponds, the water treatment avoids the use of chemical methods and is based on the phenomenon of water self-purification and the rhizofiltration capacity of repository macrophytes in TWs of the regeneration zone, as well as on typical physical filtering processes (e.g., straining, sedimentation, or flotation), physicochemical filtration (physical and chemical adsorption, mainly of phosphorus), and biological filtration (nitrification and denitrification).
