Modeling and simulation of pulp mill plant permanent magnet synchronous machines (PMSM) with damper windings using Matlab/Simulink is presented. Pulp mill is a manufacturing facility that converts wood chips, timber, wood products into wood pulp that is used to produce paper, cardboard, thick fiber board, which can be used by a paper mill for further processing. Pulp and paper industry has been considered a large consumer of energy and constitute a native treat to the plant as a result of machines transient due to heavy load variation. Modeling and simulation of pulp mill plant (PMSM) with damper windings show the behavior of machines virtual image environments to test the performance, stability and safety for less cost. It helps the pulp mill plant designers, engineers and technicians to understand the process of creating and analyzing machines model and predict its performance in the real world. Damper winding is an additional property added in pulp mill plant PMSM to damping out any oscillation that may cause any sudden changes in the load on the rotor when in synchronism. It prevents hunting and provides starting torque and dose not requires machines spinning. The rotor field lags the stator by which the load angle changes as a result of load variation. Permanent magnet synchronous machine (PMSM) is an alternating current (ac) machine whose excitation is provided by the permanent magnet. It has permanent magnet (PM) on the rotor and windings on the stator. PMSM does not have field windings on the stator frame instead, it relies on the magnets to provide the magnetic field against which the rotor interacts to produce a torque. Pulp mill plant PMSM with damper windings was modeling and simulated using Matlab/Simulink as presented in this paper. The electrical and mechanical equations of various steps ware developed in state space form from which the SIMULINK models were built with pulp mill plant PMSM with damper windings using the block-approach method with in-built Matlab/SIMULINK to obtained results for dynamics performance, controllability, stability study and is widely used in the engineering, manufacturing, physical sciences, product development and recommended for pulp mill plant designers, engineers, technicians and plant operators.

Stingless bees are a group of eusocial insects, they inhabit tropical and subtropical areas of the world and approximately 500 species are reported. In the pre-Hispanic era in Mesoamerica, vestiges of meliponiculture are reported; the relationship between the people of the civilizations of this time and the stingless bees had an important value in social, economic, and religious aspects. The objective of this study was to perform an ancestor-descendant bioinformatic analysis with molecular data (mtDNA) of the Meliponines. Nucleotide sequences of the COI-COII fragments of mtDNA were obtained from the Nucleotide sequence database at the National Center for Biotechnology Information (NCBI), using the search and Entrez functions. The fragments the sequences were aligned with cluster and then a phylogenetic analysis of the native bee species reported for Mexico in the NCBI was carried out. Based on the COI-COII mtDNA fragments, it was possible to build a phylogenetic tree, finding evolutionary relationships between the species, allowing to demonstrate that species of the Meliponini Tribe diverge from a more recent common ancestor to a less recent one.

Perceptions and treatment routines of eclampsia are complex and diverse reflective of different religious and cultural beliefs. Most often, pregnant women go for conventional options in handling the disease while neglecting the natural and cultural ways. These conflicting perceptions and treatment regimen thwarts an inclusive management of the disease. It is against this background that this study sets out to investigate perceptions, prevention strategies and treatment regimens of eclampsia. Data for this study was gotten through secondary and primary sources. Secondary data were gleaned from soft and hard copies of published and unpublished documents; journals, archives, health reports relevant to the perception and management of eclampsia. Primary data were qualitative and sourced from a sample of 239 respondents from different religious and cultural backgrounds using interviews, FGDs and observations. Data collected was processed using the Straus coding method and analysed using content analysis. Results obtained revealed that while others sees eclampsia as; common complications of pregnancy, depression and stress, others perceive it to spirituality and hereditary. However, depression and high blood pressure were outstanding. Prevention strategies were reflective of the perceptions; sufficient rest and good feeding habits while others belief in performing traditional rites and tying charms around their waist against forms of witchcraft and sorceries. On treatment regimens, prayers and deliverance, herbs and conventional ways were noted. Nature and culture were more effective in the management process. Eclampsia is associated with significant myth and perceptions. A stand-in cultural and natural way of management to decolonise conventional myths and supremacy regimen of eclampsia are recommended.

The objective is to report a clinical case of vaginal caesarean performed to save a fetus in distress by retroplacental hematoma. For this indication, the vaginal caesarean can be an alternative to the classic caesarean because of its short duration and the preservation of the possibility of future childbirth by natural means. However, this surgical technique described since the 19th century is still unknown to many practitioners and few publications exist on the subject throughout the world. Considered obsolete by some practitioners, it retains all its advantages in the practice of modern obstetrics. We report this case of fetal rescue performed by vaginal caesarean section at the Reference Health Center of the Sanitary District (District Hospital) of Bla in Mali in a 34-year-old patient, admitted for retroplacental hematoma with live fetal on a non-term pregnancy in latency phase of labor.

Science, Technology and Innovation (STI) is gradually seen by countries in Sub-Sahara African as the engine for economic growth and general uplifting of the standard of living. As a result, Innovation is embraced but institutional weaknesses hinder the required outcome. This paper's aim is to examine the connection between innovation and development in sub-Saharan Africa while considering the function of institutes and other elements. This is in light of the fact that institutions act as the lubricant for progress. The Middle East and North Africa are not included in the scope of the paper, which largely focuses on sub-Saharan African nations. Some western nations and developing economies are, nonetheless, occasionally used as comparison points. We analyze data from reputable organizations like the World Bank, Polity IV, and considering a gauge of innovation and GDP per capita, the quantity of scientific publications published as a proxy for development, the Economic Freedom of the World Project will evaluate a panel of 22 economies in sub-Saharan Africa (EFW). Our results from the POLS and GMM IV regression show, among other things, that innovation has a favorable impact on the development of Africa, even though the impact looks insignificant. Although the majority of the nations in the county have established institutional frameworks for science, technology, and innovation (STI), evidence suggests that the slow rate at which innovation contributes to national development is due to obstacles in the design and implementation of STI policies. The outcome highlights the region's little advancement in the technology-capability indicators. To establish and execute STI policies in the region, a lot more has to be done in the area of collaboration between public entities and parastatals.

Introduction: Gestational diabetes mellitus (GDM) is a common complication during pregnancy that affects both maternal and neonatal health outcomes. Identifying risk factors associated with GDM is crucial for early detection and intervention to improve pregnancy outcomes. Methods: This retrospective observational study was conducted at the Department of Gynecology, Gonoshasthaya Nagar Hospital, Dhaka, Bangladesh during the period of January 2019 to December 2019 with a total of 348 hospital patient records. Result: Of the 348 participants, 24.71% had GDM. Significant differences were observed between the groups in age, gravida, BMI distribution, family history of GDM, and previous history of GDM. Higher rates of non-spontaneous vaginal deliveries were found in the GDM group (36.05%) compared to the non-GDM group (22.52%). Age ≥35 years, obesity, family history of GDM, and history of GDM were significantly associated with GDM (p<0.05). Conclusion: Our findings support the existing evidence that advanced maternal age, obesity, family history of GDM, and previous history of GDM are significant risk factors for GDM. These results highlight the importance of early screening and intervention for high-risk groups to prevent adverse pregnancy outcomes.

When the HR job is considered in terms of its any constituents, it becomes noticeable that in every organization there are many different interacting groups that HR managers must gratify, or who have rights or a stake in what HR does. Furthermore, each comes with different and sometimes conflicting needs. It costs money and time. The most organizations try to economize with maximal effect. A way how to eliminate or reduce unnecessary expenses is making internal processes more efficient. The most expensive even the most productive factor is labor force. This paper deals with evaluating of human resource effectiveness like potential source of competitive advantage.

Darvyadi Ghrita is a polyherbal formulation and is mainly indicated for the diarrhoea. It is mentioned in Charak Samhita by Acharya Charak. Preparation of oleaginous dosage form is described as Sneha Kalpana performed by subjecting Ghrita or oil to a particular pattern of heat treated with Kalka (Paste) of Kutaja, Daruharidra, Pippali, Shunthi, Katuka, Draksha and Kwath (Decoction) of same ingredients. Murchana is a pre procedure to Sneha Kalpana in which Ghrita is treated with few drugs. The main ingredients of Darvyadi Ghrita is Kutaja (Holarrhena Antidysentrica Wall.), Daruharidra (Berberis Aristata DC.), Pippali (Piper Longum Linn.), Shunthi (Zingiber Officinale Rosc.), Katuka (Picrorhiza kurroa Royle ex.Benth), Draksha (Vitis Vinifera Linn.) and Go-Ghrita. In Ayurvedic therapeutics the Pharmacokinetics and Pharmacodynamics of the drug entirely depends upon Rasa, Virya, Vipaka, Prabhava and balance of Tridosha in the body. The ingredients of Darvyadi Ghrita with their Rasapanchaka, are very much competent to exhibit anti-bacterial and anti-diarrheal property from Ayurvedic perspective.
