Sustainability Accounting
Sustainability accounting is expanding in the academic context and business practice. It has different meanings but few definitions, and this demonstrates a lack of conceptualization in this regard. The concept is often used as a synonymous of environmental accounting, social accounting, or non-financial accounting. According to Zvezdov and Schaltegger (2013), it “entails systems, methods, and processes of creating sustainability information for transparency, accountability, and decision-making purposes. This includes the identification of relevant sustainability issues of the company, the definition of indicators and measures, data collection, overall performance tracking and measurement, as well as the communication with […] internal and external information recipients.

Industrie 4.0 in Germany
German government has recognized the need for a strategic development of Industrie 4.0 for the next decade. It set the ambitious goal in its Industrial Strategy 2030 of increasing the share of German industry in gross value added in the economy to 25% by 2030—an increase of five percentage points. Industrie 4.0 promises to be an important driver in this regard, with its target vision of the AI-driven smart factory and digital, platform-based business models. To leverage the potential of Industrie 4.0 in view of the economic, ecological, and geopolitical challenges of our time, and to follow a holistic approach for creating open digital ecosystems, strategic focus in Germany is set on three areas: sovereignty, interoperability, and sustainability.

NAFLD and Cardiovascular Comorbidities
Non-alcoholic fatty liver disease (NAFLD) is a liver disease that can progress from hepatic steatosis to steatohepatitis and even cirrhosis and hepatocellular carcinoma. From the histopathological point of view, it is characterized by excess storage of macrovesicular fat in hepatocytes. These macrovesicular storages are composed of triglycerides that accumulate in the liver. The process can lead in some individuals to an inflammatory response, which is responsible for steatohepatitis, that leads to fibrosis and, finally, cirrhosis.NAFLD has a growing prevalence in recent years. Its association with cardiovascular disease has been intensively studied, and certain correlations have been identified. The connection between these two entities has lately aroused interest regarding therapeutic management.

GSIS-Meralco Bribery Case
The GSIS-Meralco case is a political controversy and pending legal case being heard by the Supreme Court of the Philippines. This complex case began with a complaint filed by the Philippines' Government Service Insurance System (GSIS) with the Securities and Exchange Commission of the Philippines (SEC) questioning the unvalidated proxy votes used by the Lopez family in a board election of the Manila Electric Company (Meralco). The SEC issued a cease and desist order (CDO) against Meralco, which was ignored by the latter. A show cause order (SCO) was then issued by the SEC, whereupon Meralco petitioned the Court of Appeals, questioning the jurisdiction of the SEC. The Court of Appeals issued a temporary restraining order (TRO) to the SEC while the Special 9th Division composed of Associate Justices Vicente Q. Roxas, Jose L. Sabio Jr. and Myrna Dimaranan Vidal heard the case. Roxas was assigned as the ponente while Sabio was the acting chairman. Later, Sabio called a press conference and alleged that an emissary of Meralco tried to bribe him with ₱10 million to have a case transferred to another appeals court justice. The criminal charges are obstruction of justice and malfeasance in office. Sabio did not mention any names, but businessman Francis de Borja stepped forward and claimed that he was the alleged emissary, accusing Sabio of asking for a ₱50 million bribe to side with Meralco, in response to De Borja's question “What will it take for you to resist the government’s offer?” The alleged government offer was a Supreme Court position. In the latter course of the investigation, Sabio let slip that his brother, Presidential Commission on Good Government (PCGG) Chairman Camilo Sabio, called him up twice to urge him to side favorably with the government. The late admission of the allegedly unethical and criminal action called into doubt the innocence of Sabio in coming forward with his expose and the veracity of his entire story. These acts are alleged to be punishable under Article 208 and 243 of the Revised Penal Code respectively. It also came out during the course of the Supreme Court investigation that Court of Appeals Justice Vicente Roxas, the ponente of the controversial Meralco decision, had himself committed improprieties. One such impropriety was that Roxas preempted the legal opinion of Presiding Justice Conrado Vasquez that the Special 9th Division should have ruled on the case as per the Internal Rules of the Court of Appeals (IRCA), and not the 8th Division to which Roxas was transferred, and which eventually promulgated a ruling in favor of Meralco, with Justices Reyes and Apolinario Bruselas hastily signing the ponencia without going over or reading the memoranda submitted by concerned parties. The Supreme Court, voting 12–1, ordered the dismissal of Roxas after he was found guilty of multiple violations of the canons of the Code of Judicial Conduct, grave misconduct, dishonesty, undue interest and conduct prejudicial to the best interest of service. Sabio was suspended for two months after he was found guilty of simple misconduct and conduct unbecoming of a justice of the CA. Vasquez was severely reprimanded “for his failure to act promptly and decisively in order to avert the incidence that damaged the image of the Court of Appeals,” Reyes was found guilty of simple misconduct with mitigating circumstance, and Vidal was found guilty of conduct unbecoming of a justice of the appellate court for being “too compliant" when she allowed herself to sign the decision without reading the parties’ memorandum.

Lactoferrin and Ferrous Sulfate Supplementation in Iron-Deficiency Anemia
Ferrous sulfate is a commonly used iron supplement for the correction of iron-deficiency anemia but with frequent gastrointestinal side effects. Milk-derived iron-binding glycoprotein lactoferrin possesses well gastrointestinal tolerance and fewer side effects caused by the intake of high-dose iron. However, the underlying mechanism of the iron-enhancing effect of lactoferrin remains unclear. In addition, the comparative efficacies between lactoferrin and ferrous sulfate are also remained to be determined. Studies support lactoferrin as a superior supplement to ferrous sulfate regarding the improvement in serum iron parameters and hemoglobin levels.

The Scissors
The Scissors is an aerial dog fighting maneuver commonly used by military fighter pilots. It is primarily a defensive maneuver, used by an aircraft that is under attack. It consists of a series of short turns towards the attacking aircraft, slowing with each turn, in the hopes of forcing the attacker to overshoot. Performed properly, it can cause the attacking aircraft to move far enough in front to allow the defender to turn the tables and attack. The scissors is a close-maneuvering technique, and as such, is really only useful when defending against guns or low-performance missiles. It was a major technique from World War I to the Korean War, but is much less common today. The introduction of high-angle missiles makes it much less effective, as the attacker can shoot even when the defender is not in front of them. Modern aircraft also make it difficult to use this technique as they maintain energy much better than earlier designs and the maneuvering limits are often the pilot's physical limitations, not the aircraft. In fact, for many years now, fighter pilots flying aircraft with even a reasonable thrust-to-weight ratio and average wing loading are well advised to avoid engaging in a scissors maneuver, since any turning, rolling or slow-speed disadvantage the pilot's aircraft might have with respect to that of his opponent (or pilot skill in energy assessment and management techniques) will quickly become evident in the scissors, and lead to his defeat in short order. Basic fighter maneuvering theory recognizes two different types of scissors maneuvers; the flat scissors and the rolling scissors.

Dugout Canoe
A dugout canoe or simply dugout is a boat made from a hollowed tree. Other names for this type of boat are logboat and monoxylon. Monoxylon (μονόξυλον) (pl: monoxyla) is Greek -- mono- (single) + ξύλον xylon (tree) -- and is mostly used in classic Greek texts. In German, they are called Einbaum ("one tree" in English). Some, but not all, pirogues are also constructed in this manner. Dugouts are the oldest boat type archaeologists have found, dating back about 8,000 years to the Neolithic Stone Age. This is probably because they are made of massive pieces of wood, which tend to preserve better than, e.g., bark canoes. Along with bark canoe and hide kayak, dugout boats were also used by indigenous peoples of the Americas.

Stone Mountain
Stone Mountain is a quartz monzonite dome monadnock and the site of Stone Mountain Park near Stone Mountain, Georgia. At its summit, the elevation is 1,686 feet (514 m) above sea level and 825 feet (251 m) above the surrounding area. Stone Mountain is well known for not only its geology, but also the enormous rock relief on its north face, the largest bas-relief in the world. The carving depicts three Confederate figures, Jefferson Davis, Robert E. Lee and Stonewall Jackson, and has been the subject of widespread controversy. Stone Mountain was once owned by the Venable Brothers. It was purchased by the State of Georgia in 1958 "as a memorial to the Confederacy." Stone Mountain Park officially opened on April 14, 1965 – 100 years to the day after Lincoln's assassination, although the park had been in use for a few years. It is the most visited destination in the state of Georgia. Stone Mountain is more than 5 miles (8 km) in circumference at its base. The summit of the mountain can be reached by a walk-up trail on the west side of the mountain or by the Skyride aerial tram.

Natural and Synthetic Biopolymer Scaffolds
In biomedical applications, scaffolds can be used ranging from regenerative engineering to controlled drug delivery and immunomodulation, and for this purpose, biomaterials have become an indispensable instrument as scaffold material. The materials used for scaffold manufacturing must satisfy some criteria such as intrinsic biofunctionality and appropriate chemistry to stimulate molecular biorecognition by cells to induce proliferation, cell adhesion, and activation. Many biodegradable polymers of natural and synthetic origin have been established for use as biomaterials and careful consideration of the cellular environment and interactions needed is required to select a polymer for a given application.

Individualist Anarchism in France
Individualist anarchism in France has developed a line of thought that starts from the pioneering activism and writings of Pierre-Joseph Proudhon and Anselme Bellegarrigue in the mid-19th century. In the early 20th century, it produced publications such as L'En-Dehors, L'Anarchie and around its principles it found writers and activists such as Émile Armand, Han Ryner, Henri Zisly, Albert Libertad and Zo d'Axa. In the post-war years, there appeared the publication L'Unique and activist writers such as Charles-Auguste Bontemps. In contemporary times, it has found a new expression in the writings of the prolific philosopher Michel Onfray. Individualist anarchism is a group of several traditions of thought within the anarchist movement that emphasize the individual and his or her will over external determinants such as groups, society, traditions and ideological systems. French individualist anarchism was characterized by an eclectic set of currents of thought and practices which included anti-militarism, freelove, freethought, illegalism and naturism. While most American individualist anarchists advocates mutualism, a libertarian socialist from of market socialism, or a free-market socialist form of classical economics, European individualist anarchists are pluralists who advocate anarchism without adjectives and synthesis anarchism, ranging from anarcho-communist to mutualist economic types.

Ordnance QF 6-pounder
The Ordnance Quick-Firing 6-pounder 7 cwt,[note 1] or just 6-pounder, was a British 57 mm gun, serving during the Second World War as a primary anti-tank gun of both the British and United States Army (as the 57 mm Gun M1). It was also used as the main armament for a number of armoured fighting vehicles. Although designed before the start of the war, it did not reach service until the North African Campaign in April 1942. There, it replaced the 2-pounder as an anti-tank gun, allowing the 25-pounder gun-howitzer to revert to its intended artillery role.

Acute and Chronic Stress Reactions and HPA Axis
Due to the influence of various stressful stimuli, psychological stress alters the homeostasis of the organism. Consequently, the organism reacts, and the sympathetic-adrenal-medullary (SAM) system and the hypothalamic-pituitary-adrenal (HPA) axis are activated, producing and releasing specific hormones. In addition to acute stress, chronic psychological stress also activates the HPA axis, which causes elevated glucocorticoid levels.
