Herein we introduce a reliable and effective method, allowing any musician, regardless of the theoretical background, to carry out a 4-way jazz harmonization of whatever melodic progression almost instantly, with few exceptions. Many jazz students experience a deep frustration in dealing with the harmonization of non-diatonic notes. Sometimes, moreover, a coherent harmonization of the aforementioned notes can turn out to be a very challenging task even for extremely skilled professionals. In this paper, the harmonization of the chromatic scale in different harmonic contexts is accurately discussed, by resorting to the well-known concepts of harmonic functions, tonicization, chromatic and diatonic parallelism, and auxiliary chords. All the chords are labelled so as to allow the reader to immediately understand their role in the particular harmonic context. Consequently, the procedure essentially translates into an optimization of the "harmonic flow".

Active Pharmaceutical Ingredients (APIs) serve as the cornerstone of pharmaceutical development, driving therapeutic efficacy and safety in drug formulations. This article provides a comprehensive overview of the lifecycle of APIs, starting from their discovery and development, through to manufacturing processes and regulatory oversight. The development of APIs begins with intensive research and discovery efforts, where medicinal chemists and pharmacologists identify and optimize potential compounds through computational modelling, high-throughput screening, and structure-activity relationship studies. Promising candidates undergo rigorous preclinical testing to assess pharmacological properties, safety profiles, and potential adverse effects in animal models. Upon successful preclinical outcomes, APIs progress to clinical trials, involving phases of testing in human subjects to evaluate efficacy, dosage regimens, and safety profiles under controlled conditions. Clinical trial data are meticulously analyzed to support regulatory submissions, demonstrating the API's therapeutic benefits and safety for eventual patient use. Manufacturing APIs involves complex chemical synthesis or biotechnological methods, ensuring precise control over reaction conditions, purity, and yield. The scale-up from laboratory synthesis to industrial production demands adherence to Good Manufacturing Practices (GMP), where stringent quality control measures verify consistency, potency, and stability throughout production batches. Regulatory oversight by authorities such as the Food and Drug Administration (FDA) in the United States and the European Medicines Agency (EMA) in Europe ensures that APIs meet stringent standards of safety, efficacy, and quality before market approval. Manufacturers must submit comprehensive Chemistry, Manufacturing, and Controls (CMC) data, detailing manufacturing processes, analytical methods, and stability studies to support regulatory filings.

This study raises the problem of the non-repayment of agricultural credits by producers who are members of the Community Growth Mutual (MC²), in this period of COVID-19. It questions the economic mores in force in most member countries of the Organization for the Harmonization of Business Law in Africa (OHADA), where credit has become difficult for small rural farmers; And refers to the theory of the vicious circle of poverty, which advocates an indispensable recourse to foreign capital in the event of financial breakdown, as a means of increasing capital. Since the capital of rural producers remains insufficient and their possibility of reinvestment decreases, then becomes zero because of agricultural credit. To understand the factors of the non-repayment of these credits, data were collected from 100 agro-sylvo-pastoral producers of the Bayangam group (West-Cameroon) of both sexes, aged at least 18 years, having obtained an unpaid credit from the MC² since 2019, and a manager of this microfinance institution. After analysis, it appears that beyond overproduction and anti-COVID-19 measures that lead to the missale or fall in prices on the market, the conditions of access to credit, the non-possession of acceptable guarantees, the misuse of the object of credit and the practice of financial cavalry by the borrower, as well as the rigidity of the procedures for prosecuting debtors significantly explain this non-repayment. It is associated with determinants such as age, level of education, marital status, type of agricultural activity of the debtor. Hence the need for flexibility of microfinance institutions vis-à-vis rural agro-sylvo-pastoral producers, who are severely affected by the economic shock of the COVID-19.
