Classroom Management
Classroom Management is a term teachers use to describe the process of ensuring that classroom lessons run smoothly without disruptive behavior from students compromising the delivery of instruction. The term also implies the prevention of disruptive behavior preemptively, as well as effectively responding to it after it happens. It is a difficult aspect of teaching for many teachers. Problems in this area causes some to leave teaching. In 1981, the US National Educational Association reported that 36% of teachers said they would probably not go into teaching if they had to decide again. A major reason was negative student attitudes and discipline. Classroom management is crucial in classrooms because it supports the proper execution of curriculum development, developing best teaching practices, and putting them into action. Classroom management can be explained as the actions and directions that teachers use to create a successful learning environment; indeed, having a positive impact on students achieving given learning requirements and goals (Soheili, Alizadeh, Murphy, Bajestani, Ferguson and Dreikurs). In an effort to ensure all students receive the best education it would seem beneficial for educator programs to spend more time and effort in ensuring educators and instructors are well versed in classroom management. Teachers do not focus on learning classroom management, because higher education programs do not put an emphasis on the teacher attaining classroom management; indeed, the focus is on creating a conducive learning atmosphere for the students (Eisenman, Edwards, and Cushman). These tools enable teachers to have the resources available to properly and successfully educate upcoming generations, and ensure future successes as a nation. According to Moskowitz & Hayman (1976), once a teacher loses control of their classroom, it becomes increasingly more difficult for them to regain that control. Also, research from Berliner (1988) and Brophy & Good (1986) shows that the time a teacher must take to correct misbehavior caused by poor classroom management skills results in a lower rate of academic engagement in the classroom. From the student's perspective, effective classroom management involves clear communication of behavioral and academic expectations as well as a cooperative learning environment.

Rooftop Photovoltaic Power Station
A rooftop photovoltaic power station, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. Rooftop mounted systems are small compared to ground-mounted photovoltaic power stations with capacities in the megawatt range, hence being a form of distributed generation. Most rooftop PV stations in developed countries are Grid-connected photovoltaic power systems. Rooftop PV systems on residential buildings typically feature a capacity of about 5 to 20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts to 1 Megawatt (MW). Very large roofs can house industrial scale PV systems in the range of 1-10 Megawatts.

Kidney Issues Associated with COVID-19 Disease
Infection with SARS-CoV-2 and the resulting COVID-19 can cause both lung and kidney damage. SARS-CoV-2 can directly infect renal cells expressing ACE2 receptors, resulting in kidney damage, and acute kidney injury (AKI) has been reported in COVID-19 hospitalized patients. The pathophysiology of COVID-19-associated AKI is multifactorial. Local and systemic inflammation, immune system dysregulation, blood coagulation disorders, and activation of the renin-angiotensin-aldosterone system (RAAS) are factors that contribute to the development of AKI in COVID 19 disease. COVID-19 patients with kidney involvement have a poor prognosis, and patients with chronic kidney disease (CKD) infected with SARS-CoV-2 have an increased mortality risk. CKD patients with COVID-19 may develop end-stage renal disease (ESRD) requiring dialysis. In particular, patients infected with SARS-CoV-2 and requiring dialysis, as well as patients who have undergone kidney transplantation, have an increased risk of mortality and require special consideration. Nephrologists and infectious disease specialists face several clinical dilemmas in the prophylaxis and treatment of CKD patients with COVID-19. This entry presents recent data showing the effects of COVID-19 on the kidneys and CKD patients and the challenges in the management of CKD patients with COVID-19, and discusses treatment strategies for these patients.

Stitched Textile Strain Sensors
By embedding conductive yarns in, or onto, knitted textile fabrics, simple but robust stretch sensor garments can be manufactured. In that way resistance based sensors can be fully integrated in textiles without compromising wearing comfort, stretchiness, washability, and ease of use in daily life. The many studies on such textile strain sensors that have been published in recent years show that these sensors work in principle, but closer inspection reveals that many of them still have severe practical limitations like a too narrow working range, lack of sensitivity, and undesired time-dependent and hysteresis effects. For those that intend to use this technology it is difficult to determine which manufacturing parameters, shape, stitch type, and materials to apply to realize a functional sensor for a given application.

Taro Mucilage
Taro (Colocasia esculenta) is an important source of carbohydrates as an energy source and is used as a staple food throughout the world. It is rich in mucilage and starch granules, making it a highly digestible ingredient. Mucilage can act as a matrix and a thickening, binding, emulsifying, or foaming agent in food, pharmaceutical, and several other fields of research. Moreover, mucilage can be extracted from several living organisms and has excellent functional properties, such as water-holding, oil-holding, and swelling capacities. Therefore, these remarkable functional properties make mucilage a promising ingredient with possible industrial applications. Furthermore, several extraction techniques, including enzyme-assisted, ultrasonication, microwave-assisted, aquatic, and solvent extraction methods, are used to obtain quantitative amounts of taro mucilage. Coldwater extraction with ethanol precipitation can be considered an effective and cost-effective technique to obtain high-quality mucilage with suitable industrial applications, whereas the ultrasonication method is more expensive but results in a higher amount of mucilage than other emerging techniques. Mucilage can also be used as a fat replacer or reducer, dye remover, coating agent, and antioxidating agent

Short Chronology
The short chronology is one of the chronologies of the Near Eastern Bronze and Early Iron Age, which fixes the reign of Hammurabi to 1728–1686 BC and the sack of Babylon to 1531 BC. The absolute 2nd millennium BC dates resulting from these reference points have very little academic support, and have essentially been disproved by recent dendrochronology research. The middle chronology (reign of Hammurabi 1792–1750 BC) is more commonly accepted in academic literature. For much of the period in question, middle chronology dates can be calculated by adding 64 years to the corresponding short chronology date (e.g. 1728 BC in short chronology corresponds to 1792 in middle chronology). After the so-called "dark age" between the fall of Babylon and the rise of the Kassite dynasty in Babylonia, absolute dating becomes less uncertain. While exact dates are still not agreed upon, the 64-year middle/short chronology gap ceases from the beginning of the Third Babylon Dynasty onward.

Orphan Train
The Orphan Train Movement was a supervised welfare program that transported orphaned and homeless children from crowded Eastern cities of the United States to foster homes located largely in rural areas of the Midwest. The orphan trains operated between 1854 and 1929, relocating about 200,000 orphaned, abandoned, or homeless children. Three charitable institutions, Children's billage (founded 1851 by 24 philanthropists), the Children's Aid Society (established 1853 by Charles Loring Brace) and later, the New York Foundling Hospital, endeavored to help these children. The institutions were supported by wealthy donors and operated by professional staff. The two institutions developed a program that placed homeless, orphaned, and abandoned city children, who numbered an estimated 30,000 in New York City alone in the 1850s, in foster homes throughout the country. The children were transported to their new homes on trains that were labeled "orphan trains" or "baby trains". This relocation of children ended in the 1920s with the beginning of organized foster care in America.

4D Printing Technologies
3D printing has played a crucial role in the last decades as an innovative technology for tissue and organ fabrication, patient-specific orthoses, drug delivery, and surgical planning. However, biomedical materials used for 3D printing are usually static and unable to dynamically respond or transform within the internal environment of the body. These materials are fabricated ex situ, which involves first printing on a planar substrate and then deploying it to the target surface, thus resulting in a possible mismatch between the printed part and the target surfaces. The emergence of 4D printing addresses some of these drawbacks, opening an attractive path for the biomedical sector. By preprogramming smart materials, 4D printing is able to manufacture structures that dynamically respond to external stimuli. Despite these potentials, 4D printed dynamic materials are still in their infancy of development. The rise of artificial intelligence (AI) could push these technologies forward enlarging their applicability, boosting the design space of smart materials by selecting promising ones with desired architectures, properties, and functions, reducing the time to manufacturing, and allowing the in situ printing directly on target surfaces achieving high-fidelity of human body micro-structures.

Sperm in Honey Bee Drones
The quality of honey bee drone semen is relevant in different contexts, ranging from colony productivity to pathology, toxicology and biodiversity preservation. Despite its importance, considerably less knowledge is available on this subject for the honey bee when compared to other domestic animal species. A proper assessment of sperm quality requires a multiple testing approach which discriminates between the different aspects of sperm integrity and functionality. Most studies on drone semen quality have only assessed a few parameters, such as sperm volume, sperm concentration and/or sperm plasma membrane integrity.
