Abstract: Cardano investigated del Ferro's papers and found that he had discovered the solution to the cubic before Tartaglia. Anxious to publish the solutions to the cubic, and not wanting to betray Tartaglia, Cardano used the fact that del Ferro had discovered the solution first to evade his promise of secrecy. Although Cardano expanded on his Islamic predecessors by including the possibility of negative solutions, he was still not able to find all the possible solutions to cubic equations. Rafael Bombelli continued to expand on, and refine, the work of Cardano. Bombelli wrote a book that contained a logical progression from linear to quadratic to cubic equations. He also included the idea that it seemed possible to take the square root of a negative number, something that is encountered when using Cardano's formula for some cubic equations. He used notation that was a stepping stone toward the notation currently used in algebra. For example, Bombelli began writing R.Sq. to represent the square root. Bombelli also noted that it was possible to take the cube root of numbers that were negatives. He noted that this required a, different set of rules for these new numbers, which he called "plus of plus" and "minus of minus" (Katz, 1998). In modern terms, Bombelli had begun working with imaginary numbers.

Abstract: Selenium (Se) has a special place among the feed-derived natural antioxidants, being an integral part of selenoproteins participating in the regulation of various physiological processes in the body. As a part of glutathione peroxidase (GSH-Px) Se belongs to the first and second major levels of antioxidant defense in the cell. There are two major sources of Se for poultry organic selenium, mainly in the form of selenomethionine (SeMet), which can be found in any feed ingredient in varying concentrations and inorganic selenium, mainly selenite or selenate, which are widely used for dietary supplementation. There is a principal difference in metabolism and efficiency of these two forms of selenium, with SeMet being more effective. In fact SeMet possesses antioxidant properties, however, in some conditions selenite can be a pro-oxidant. Selenium deficiency and excess in modern poultry production are very rare. In general, adequate Se supplementation is considered to be a crucial factor in maintaining the high productive and reproductive characteristics of commercial poultry The present research focuses on the effects of Se on meat and egg quality, antioxidant activity of Se, effects on fatty acid levels, activity of glutathione-peroxidase, or the effect of Se on the immune system. Ensuring natural Se supply in human nutrition by food of animal origin, mainly poultry meat and eggs.

Abstract: Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus is mainly spread during close contact and via respiratory droplets that are produced when a person talks, coughs, or sneezes. Respiratory droplets may be produced during breathing, however, current research indicates that the virus is not considered airborne. People may also contract COVID-19 by touching a contaminated surface (Fomite) and then inadvertently transfer the pathogen to a mucous membrane (such as the eyes, nose, or mouth). It is most contagious when people are symptomatic, although spread may be possible before symptoms appear. The virus can live on surfaces up to 72 hours. Time from exposure to onset of symptoms is generally between two and fourteen days, with an average of five days. The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. The infection can also be diagnosed from a combination of symptoms, risk factors and a chest CT scan showing features of pneumonia. This article introduces recent research reports as references in the related studies.

Invent the Global Monsoon Time Scales for world monsoon regions & countries

Abstract: There are many global monsoon systems, regional monsoon systems and sub-regional monsoon systems in the world. In fact each and every region and country has it’s own monsoon winds. Monsoon Time Scales for all world regions and countries are proposed and designed by me to study their regions and countries. So world scientists can make the Monsoon Time Scales and study their monsoon systems. Find out and study them just prefixing a monsoon region or country name to Monsoon Time Scale and searching in all websites just like as AUSTRALIAN MONSOON TIME SCALE. I urge world scientists to invent and make further researches on this scale. Scientists who want to invent this scale and to do further researches on the monsoon have trouble in making it, kindly contact me at my personal email id gangadhar19582058@gmail.com and take my assistance. I will create a model manual scale and send it for your studies. For this, pay some amount along with data of list of monsoon pulses in the form of low pressure systems, depressions and storms formed over this monsoon region last 140 & above years since 1880 as cited in the Reference-1 (i.e Mooley DA, Shukla J (1987); Characteristics of the west ward-moving summer monsoon low pressure systems over the Indian region and their relationship with the monsoon rainfall. centre for ocean-land atmospheric interactions, university of Maryland, college park, MD.) have been taken as the data to the construct this scale. Scientists who make those Monsoon Time Scales have trouble in making it, kindly take my assistance in making the Monsoon Time Scales. Email id to contact me is gangadhar19582058@gmail.com. I will create model Monsoon Time Scales and send the same to them for study. For this, they must send the list of events of climate just like dust storms, monsoon low pressure systems etc. last 140 years since 1880 formed over their country’s regions in the procedure cited below reference. In addition to this, a certain amount should be sent for expenses. You need to design the computer model later.
