Published: January 2024

Every plant has a different secondary metabolite content, influenced by the location and conditions where the plant grows. Preparations from the butterfly pea flower (Clitoria ternatea L.) extract form have poor bioavailability. One effort to overcome this problem is by formulating it into nanoherbs form. This research aims to determine the phytochemical content and synthesize nanoherbs ethanol extract of butterfly pea flowers. The butterfly pea flowers were extracted using the maceration method, and the resulting thick purplish blue extract was 145.254 grams. The thick extract was analyzed for secondary metabolite content using phytochemical screening, and it was found to contain alkaloids, flavonoids, saponins, triterpenoids, and tannins. Nanoherb synthesis uses the ionic gelation method with an alginate polymer and a CaCl2 cross-linking agent. The synthesis result is a purple nanoherbs colloid with optimal variations in the ratio (10:1). The synthesized nanoherbs were characterized using PSA and obtained particle size results from the optimal variation of 220.4 nm, polydispersity index 0.2550, and zeta potential of -22.5 mV.

Published: January 2024

It is widely recognized that poultry farming productivity is not only influenced by technology/inputs enhancements but also by the efficiency with which available technologies/inputs are used. Technical inefficiency has also been attributed to farmer’s inability to correctly use farm inputs as prescribed, poor management practices etc. all of which are affected by the farmers’ level of knowledge. This study broadly assessed the effect of educational level of poultry egg farmers on their technical efficiency. A 4-stage sampling procedure was used to select 180 respondents. Structured questionnaire was administered to obtain data; descriptive analysis was used to assess educational level, Data Envelopment Analysis (DEA) to estimate technical efficiency, robust Ordinary Least Square regression to determine the effect of educational level on the farmers’ technical efficiency. This study found that 65.5% of the respondents had tertiary education, 15.6% had secondary education, 5% had primary education and 13.9% had no formal education. The mean efficiency of the respondents is 0.426, implying that they are more technically inefficient (57.4%) than they are technically efficient (42.6%). Secondary and tertiary education were found to have positive significant effects on the technical efficiency of the respondents at 1%. That is, farmers’ technical efficiency does not stop increasing at tertiary level of education as further search for knowledge facilitates higher efficiency. Therefore, it is recommended that poultry farmers should frequently undergo adequate and relevant education, workshop and training; adopt input minimisation and output maximisation management practices. Manual/literature accompanying drugs, vaccines and other poultry inputs should be clearly explained.

Introduction and importance: Angiosarcoma is a malignant vascular tumour of bone composed of endothelial cells. It accounts for 1% of all malignant bone tumours. The interest of this observation is to show the particularly aggressive and devastating nature of this type of tumour, which remains very rare and whose evolution is totally unpredictable. Case presentation: This was an angiosarcoma of the tibia in a 29-year-old patient with no particular pathological history, which according to the patient had appeared 3 months previously. A radiological work-up confirmed the malignant nature of the lesion, hence the need for a biopsy, which confirmed the diagnosis of angiosarcoma. Clinical discussion: Angiosarcoma is defined by its high histological degree of anaplasia, its radiological aggressiveness and its rapid clinical course with a very high metastatic potential. It is a rare tumour that occurs mainly in adults aged between 20 and 60, with a predominance of males. CT and MRI are used to define the limits of the tumour, biopsy confirms the diagnosis, and treatment is surgical. Conclusion: Angiosarcoma is an angioendothelioma with a high grade of malignancy, the course of which is usually lethal whatever the treatment used.

Sixty broilers of five weeks old were used for the study which lasted for five weeks. The birds were assigned to four treatment diets with three replicates. The finisher rations were formulated in which PLM was incorporated at 0.5%, 1.5% and 2.0% in T2, T3 and T4 respectively. T1 had no PLM and served as the control diet. The diets were isocaloric and isonitrogenous containing 2,850kcal ME/kg and 20% crude protein. At the end of the experiment, data collected on haematological and carcass characteristics were subjected to analysis of variance (ANOVA) in a completely Randomized Design (CRD). Results showed that there were significant (p < 0.05) improvements on the haematological and carcass characteristics of birds fed the treatment diets. Birds on T4 diets had (p <0.05) better haemoglobin concentration (Hb) of 10.17 and packed cell volume (PCV) of (31%) as against the control diet of Hb (8.09%) and PCV (25.97%). The carcass characteristics of the birds followed similar trend in which T4 had significant higher values of 2,168g and 73.90% for dressed weight and dressed % respectively while T1 (control) had the lowest values of 1,786g and 68.96% for dressed weight and dressed% respectively. It is concluded that incorporating 2.0% PLM (T4) into the diets of broilers helped to improve the hematopoietic tissue resulting in an enhanced haematological indices and carcass yield of the broiler birds.

The second section delves into several ML methodologies utilised in cybersecurity, including supervised and unsupervised learning, deep learning, and reinforcement learning. Every approach is assessed based on its suitability for threat detection, demonstrating its advantages and constraints. Furthermore, the relevance of feature engineering and data pretreatment in improving machine learning models for cybersecurity applications. The versatility of ML algorithms allows them to grow with emerging threats, making them a useful tool in the ever-changing arena of cyber warfare. The final segment focuses on real-world applications of machine learning in cybersecurity, presenting successful use cases across sectors. From anomaly detection to behavior analysis, ML algorithms contribute to the discovery of dangerous activity, lowering false positives and strengthening the overall security posture. Lastly, the paper covers the obstacles and ethical issues related to the adoption of ML in cybersecurity. Issues like as adversarial assaults, skewed datasets, and the interpretability of ML models are examined, highlighting the necessity for a holistic strategy that integrates modern technology with ethical considerations. The fusion of human expertise and machine intelligence offers a formidable defense against evolving cyber threats, paving the way for a more resilient and secure digital future.

In the industrial world, we have definitely met with induction motors, both 1-phase and 3-phase voltage sources. Induction motors are widely used today, because they have simple construction, are inexpensive, relatively light, have high efficiency and are easy to maintain compared to DC motors. However, in terms of adjusting the speed and torque of this motor is not an easy problem, with the development of technology, this can be overcome by using an inverter. The inverter used is a Variable Speed Drive (VSD) Inverter type. This inverter can convert and regulate 3 phase voltage sources between 0 – 60 Hz depending on the specifications of the inverter used. In this study the ladder diagram program was designed using TIA Portal V15.1 on a Programable Logic Controller (PLC) which is used to control the speed of a 3 phase induction motor through the Human Machine Interface (HMI) which is connected to the inverter. The controlled frequency is 0 – 50 Hz and the resulting rotation is 0 – 1400 rpm. The greater the frequency data that is set, the speed of the induction motor will be faster.
