Surah As-Sajdah is the 32nd chapter of the Quran, consisting of 30 verses (ayat). The term "As-Sajdah" translates to "The Prostration" or "The Adoration" in English. This surah is named after the prostration (sajdah) mentioned in verse 15, where it describes believers prostrating in worship to Allah.

Artificial satellites are human-made objects placed into orbit around celestial bodies, primarily Earth, to serve various purposes. These satellites are integral to modern space exploration, communication, Earth observation, navigation, and scientific research. They come in different sizes and functionalities, ranging from large communication satellites to small CubeSats. Satellites are launched into specific orbits, such as Low Earth Orbit (LEO), Medium Earth Orbit (MEO), or Geostationary Orbit (GEO), depending on their intended missions. Equipped with communication payloads, sensors, cameras, and scientific instruments, artificial satellites relay data, capture images, monitor environmental changes, facilitate global communication, and contribute to our understanding of the cosmos. The continuous evolution of satellite technologies reflects humanity's commitment to expanding knowledge, improving connectivity, and addressing challenges through innovative space-based solutions.

The world is watching with worries the ongoing Israel versus Palestine Conflict 2023 which started after the Hamas group targeted the major cities of Israel on 7th October 2023. In response Israel is responding with all kinds of sophisticated war weapons and air planes, drones in against of unarmed Palestinian civilian to this sudden attack launched by the Palestinian Militant Group Hamas early Saturday morning. Israeli ministers have declared a “Complete siege” on the already blockaded and destitute Gaza Strip, denying its more than two millions residents a supply of food, water and electricity. Hamas has also kidnapped more than two hundred Israeli citizens, soldiers and foreigners. Since Israel’s inception back in May 14, 1948, it has heavily prioritized investments in education and technological development to safeguard its sovereignty against neighboring Arab nations. In contrast, other Arab countries have traditionally shied away from educational and technological advancements due to certain religious convictions and beliefs.

The initial shipment of uranium destined for Bangladesh’s largest and sole nuclear power plant project arrived in Dhaka, the capital of Bangladesh, on Thursday, according to an official closely associated with the endeavor who preferred to remain anonymous. A specialized air cargo aircraft from Russia transported the nuclear fuel, touching down at Dhaka’s Shahjalal International Airport, the official disclosed. The scheduled handover of the fuel to the Rooppur Nuclear Power Plant (RNPP) project authority is set to take place on October 5, with an anticipated virtual handover ceremony anticipated to be attended by Prime Minister Sheikh Hasina and Russian President Vladimir Putin. In July, Alexey Likhachev, the Director General of Russia’s nuclear energy corporation, Rosatom, assured Prime Minister Hasina that despite numerous challenges faced by the project, Bangladesh would receive the fuel in September. The Rooppur Nuclear Power Plant (RNPP), a $12.65 billion undertaking, is being constructed with substantial financial backing from Russia, covering 90% of the project’s costs. Bangladesh will assume responsibility for repaying the loan over a 28-year period, which includes a 10-year grace period. Rosatom is offering technical support for the project’s implementation, with the objective of addressing Bangladesh’s increasing electricity demands and fostering socio-economic advancement. Situated in the western district of Pabna, the plant comprises two units, each boasting a capacity of 1,200 megawatts. Bangladesh is on track to inaugurate the first unit in September next year.

In this article, I want to share some of the valuable advice bestowed upon me by my esteemed father before I embarked on my journey from my beloved birthplace, Bangladesh, to pursue higher education in the USA. My father, a sincere, devoted, and humble college professor and principal, authored around 15 books that encapsulated his life's vision and mission. Throughout his lifetime, he established numerous cultural organizations to foster harmony and coexistence among individuals of diverse religious backgrounds and gender differences. Regrettably, I must confess that I could not fully uphold his invaluable counsel while residing in a foreign land. Consequently, during his initial and final visit to the USA in 1989, he implored us to return to Bangladesh and contribute to the needs of our homeland. In response to his fervent wish, we did indeed return in 1995, albeit it was a belated endeavor as he had already passed away in 1992. Regrettably, we were unable to support him during his final years when he needed it most. Nonetheless, I am sharing his invaluable advice with you, in the hopes that it may be of assistance to you and future generations as you navigate life in a foreign country.

This article will study and present different fossil fuels separately to know about their reserve, production, consumption, price, and their corresponding CO2 emissions. The analyses will be carried out at the country and global levels to reveal and identify the potential contributors of the CO2 emissions and make recommendations to reduce the global temperature rise. Also, the impact of fossil fuels on climate change of our planet will be studied and presented. Furthermore, how global warming above 1.5oC threshold level is impacting the rise of sea level, creating extreme weather condition, biodiversity loss and species extinction, as well as food scarcity, worsening health and poverty for millions of people worldwide will be thoroughly investigated.

About 87 percent of all human generated carbon dioxide (CO2) emissions come from the combustion or burning of fossil fuels like coal, natural gas and oil. Carbon dioxide emissions, largely by-products of energy production and use, account for the largest contributor of greenhouse gases, which are associated with global warming is measured in kt (kiloton) often calculated and reported as elemental carbon. This article will study and present each of these three fossil fuels separately to know about their reserve, production, consumption, price, and their corresponding CO2 emissions. The analyses will be carried out at the country and global levels to reveal and identify the potential contributors of the CO2 emissions and make recommendations to reduce the global temperature rise. Also, the impact of fossil fuels on climate change of our planet will be studied and presented.

The Monty Hall problem is a brain teaser, originated from the American television game show *Let's Make a Deal* and named after its original host, Monty Hall. It is basically a probability puzzle, originally posed (and solved) in a letter by Steve Selvin to the American Statistician in 1975. It became famous as a question from reader Craig F. Whitaker's letter quoted in Marilyn vos Savant's "Ask Marilyn" column in Parade magazine in 1990.

Medical practitioners, physicians, nurses have extremely difficult tasks in determining the course of action in determining the diseases and their respective treatments. At no circumstance a doctor or nurse decide to kill a patient due to the severity of patients or any other racially motivated issues or stigmas. Also, medical practitioners cannot give up and let the patient suicide to end her/his life because of any shortcomings and insurance policies. This is where our baseline ethical and moral fine line has to be drawn to distinguish between righteous and wrongdoers. An ailing patient in a death bed is helpless and what else she/he can do rather than trusting a doctor. A morally corrupt person cannot be given a task to be a medical practitioner simply her/his inability to distinguish between right and wrong. Some times medical practitioners and patients value system could be in direct conflict. In the most of the Abrahamic religions no person is allowed to commit suicide. Therefore it is not right to impose a death sentence to kill an ailing patient without letting her/him know her/his wish or conviction. It is absolutely unethical by medical practitioners to withheld or end treatment because of insurance and hospital financial budget.

The first capstone project of the HarvardX Data Science Professional Certificate Series is a recommendation system on MovieLens. A 10M MovieLens dataset was made available from GroupLens Research Lab to make the analysis. To apply the required machine learning algorithms the given movielens dataset was partitioned to create edx and validation sets. Two different algorithms were used on the edx set to predict movie ratings in the unknown validation set to find the RMSE for accuracy determination of the predictions. Penalized Least Squares and Matrix Factorization with Parallel Stochastic Gradient Descent (SGD) methods were used to find the RMSEs keeping the genres combined. RMSEs were also calculated with genres separated in both methods. The RMSE value with genres separated showed about 10% improvement over genres combined in the MF-SGD method but no such change happened in the Penalized Least Squares method. Therefore, without proper consideration of genre, optimal RMSE cannot be obtained.

In this study propagation pattern of the COVID19 pandemic in US is made using a widely used SIR model. A R-library is created to fetch the COVID19 data from JHU-CCSE to predict the propagation pattern over a period of 130 days starting from the first US reported death on February 29 upto the projected end sometime in the second week of July, 2020. In this analysis initial population, N is cosidered to be 20.23M which is the combined population of New York City (8.399M), Washington (7.615) and Oregon (4.218). We calculated the optimized parameter $\beta$ that controls the transition between S to I (susceptible (S) to infectious (I)) and $\gamma$ that controls the transition between I to R ( infectious (I) to recovered (R)) to be 0.6391959 and 0.4476751 respectively. Furthermore, we estimated the reproduction number of 1.43, and using the formula $1-\frac{1}{R_{0}} = 1 - \frac{1}{1.43} = 0.3007$, about 30.00% of the population of US which is about 99.30 million, need to be vaccinated to stop the pandemic in the future. Based on the available US data for the period of February 29 to May 9, the model preddicts what happens if the pandemic continues over a total time span of 130 days or longer. It is estimated from the analysis that peak infected case already happened around May 01, 2020, and the pandemic is expected to come back to the normal state sometime at the end of first week of July, 2020. This paper is based on the similar case study reported in [1] but adapted for US with modfifications with our own library and methods.
