Funding is very critical for the sustainability of special education. Funding aids in the realization of special educational objectives. Funding of special education is affected under depressed economy. This paper looked at the concept of funding, concept of depressed economics and the concept of alternatives sources. This paper also discussed various alternatives sources of funding options available for special education in a depressed economy. Relying on secondary data that were collected from print and online publications, the paper identified public private partnerships (PPPs), non-governmental organisations (NGOs), international development agencies, community partnership, donations from individuals and charitable organisations, endowment funds, old boy association partnership as some of the alternatives sources of funding available for funding of special education in a depressed economy. Based on this, the paper recommended that special education managers should embrace public private partnerships (PPPs) model, non-governmental organisations (NGOs) strategy, international development agencies strategy, community partnership strategy, donations from individuals and charitable organisations strategy, endowment funds strategy and old boy association partnership strategy to raise more fund to administer the special education institutions in the economy depressed era.

Mathematical culture is an abstract concept in relation to fundamental characteristics in the quality and thinking of math learners. Not only does teaching math help learners obtain rules, methods, and strategies for solving the math problems in the process of math study but it also shows the learners with the reality value of learning math in tight relation to nature and society. In the context of innovations in the General Education Program in Mathematics 2018 and the educational objectives in the new era of Vietnam, teaching mathematical culture to students calls for special interest and determined action. On the basis of fundamental characteristics in the concept of Mathematics and objectives in the General Education Program in Mathematics 2018, we proposed some solutions of teaching Mathematical culture effectively by demonstrating examples in the topic: “Natural logarithm” – 6th grade Math. Teaching Mathematical culture at schools still draws little attention and emphasis. Proposing some measures of supporting teachers to overcome this difficulty shall make a positive impact on students' and teachers' awareness of the meaning and role of Mathematical culture in the process of learners’ comprehensive development.

This paper presents the steady-state thermal and static structural modelling of a laboratory-scale pyrolysis reactor for the thermal degradation of biomass wastes. A laboratory-scale pyrolysis reactor of volume 9.203 x 10-3m3 was developed to pyrolyse Palm Kernel Shell (PKS) and Palm Fruit Bunch (PFB) at varying temperatures of 350oC, 400oC, 450oC, 500oC, and 550oC. The reactor chamber was simulated for static-steady thermal and static structural analysis to determine the temperature distribution and thermal stresses induced in it. The model was developed using SolidWorks software, and a Computational Fluid Dynamics (CFD) simulation was carried out using ANSYS Workbench 19. A total number of 2,459 elements was generated composed of 8630 nodes using Hexahedra dominant meshing method. It was observed from the simulation result that the temperature distribution inside and outside the reactor chamber were 454.29oC and 550oC respectively. The maximum heat flux of 8.3466e+005 W/m² occurred at the inner chamber of the reactor due to the high concentration of the biomass waste and devolatization reaction, and the maximum equivalent (von-Mises) stresses the material can withstand at higher temperature is 1.6674e+009 Pa without rupture. It was found out from the simulation result that at a maximum temperature of 550oC, the equivalent (von Mises) stresses induced at the outer and inner chamber is 1.8585e+008 Pa, which is far lower than the maximum stress the material can withstand without rupture. Thus, the reactor is safe to operate at a temperature higher than 550oC without failure.

Objectives: To assess the level of awareness among obstetrical care providers about preeclampsia prevention including risk factors, good practice in aspirin prophylaxis, and to analyze the associated factors. Methods: A cross-sectional study conducted among gynecologists and obstetricians, maternal and fetal medicine specialists, and internal or family medicine physicians working in public or private care centers whom involved in obstetric care in Saudi Arabia. An online-administered questionnaire was designed to assess familiarity of aspirin role in prevention of preeclampsia and fetal growth restriction including proper dose, timing of intake, gestational age to start and discontinuation of treatment as well as the risk factors of PE among set of 13 conditions. An awareness score was calculated and divided into two levels: adequate and inadequate familiarity and knowledge. Practice in PE prevention and attitude towards aspirin use, in addition to participants’ demographic and professional factors, were investigated and analyzed as profound factors. Results: Hundred sixty physicians were participated, 85% were obstetrician/gynecologists and 13.1 were maternal fetal medicine Specialists. Less than half of participants have adequate knowledge and awareness in aspirin role and a minority provided correct answers regarding the recommended aspiring dose, timing of intake, gestational age to start and discontinuation of treatment. However, knowledge about preeclampsia risk factors was relatively acceptable. Maternal fetal medicine specialist and physicians working in teaching hospitals were remarkably with better knowledge compared to their respective counterparts in primary and secondary centers. The existence of institutional guidelines about ASA use in pregnancy did not improve the knowledge level. Conclusion: The overall familiarity and knowledge in that regard was relatively poor, associating misconceptions about the risk factors and substantial gaps regarding the optimal timing and prescribing practice. Formal and continuous medical education curricula should be reviewed to promote good clinical practice in preeclampsia prevention as an essential dimension of maternal and fetal care.

Drying is an important unit operation in the processing of fresh cassava tubers into cassava chips. An air flow meter is a device that measure airflow. Airflow meter and direction sensing are importance in many fields, including the monitoring on vehicle engine performance. The airflow meter for cassava chips measures how much air is flowing through the cassava chips. There are many reasons and ways to measure airflow, this technical method of explores the use of air flow meter to measure cassava chips in order to ensure the proper airflow to dry the cassava chip, which will improve the value chain of cassava processing. This research work focused on the design and performance evaluation of an airflow meter for drying cassava chips. The air flow meter was made from locally available materials and it consists of a blower, pressure, sensor, temperature sensor, heating chamber which was used to carry out several tests on cassava chips. From the test conducted during drying operation, at a temperature of 900c for a 372g of cassava chips, it takes a period of 180 minutes (3hours) with an airflow of 133m3/sec to dry it to a safe moisture content. At temperature 1100c for 617g of cassava chips, it takes a period of 240 minutes (4hours) with an airflow of 209m3/sec to dry it to safe moisture content. The efficiencies of the drying mechanism and measuring airflow device are 70% and 65% respectively. The sample dried with airflow meter still retain their white colours, thus indicating no mould growth.

Objectives: The objective of present study was to develop chitosan-based sustained release Levofloxacin microspheres to reduce the dosing frequency. Materials and Methods: The Levofloxacin -loaded microspheres were prepared by emulsification cross-linking method using glutaraldehyde as cross-linking agent. Accurately weighed quantity of Chitosan was dissolved in 1% (v/v) aqueous acetic acid. Results: The percentage yield of the emulsification cross-linking method was determined to be between 74 and 81.5 percent, and the spherical microspheres had particle sizes ranging from 2 m to 200 m. According to the in vitro dissolution analysis of the improved formulation (F2) (table 7.8), when the medication was enclosed in Chitosan microspheres, 95 percent of the formulation was released after 12 hours, demonstrating that the drug is released from the formulation in a controlled way. Conclusions: The percentage of entrapment effectiveness, particle size, and percentage of drug release were significantly impacted by the drug: polymer ratio and GA volume. According to research using scanning electron microscopy (SEM), microspheres were round and had a smooth surface. Nicorandil-loaded chitosan microsphere formulations released their drugs via fickian diffusion.

One of the directions for making cleaner and more economic vehicles is to adopt electric vehicle concept. Therefore, an internal combustion powered engine Nissan Micra Vehicle was converted into battery powered electric vehicle. The power train of the car was redesigned to use DC electric motor in replacement of the existing internal combustion engine and to give the gear ratios possibility of a normal car. The power rating of the motor was determined by considering the rolling, gradient and aerodynamic resistances which gave a total tractive effort of 12190.84 N. The designed power rating was then determined to be 8 kW and this value was used to select the number of batteries that gave the required current to reach an adequate range of operation. To balance the weight of the car, the battery rack was located behind the center of gravity to give the developed vehicle a neutral steer characteristic. After installation of electric motor, inverter and the batteries, then the batteries were connected in series and parallel to the inverter with cable wire via variable frequency drive to ac motor and potentiometer. The vehicle was then evaluated and the voltage produced was able to move the vehicle at 6.24 m/s and the maximum frequency obtained was fifty megahertz (50 MHz).

This work characterizes the geotechnical properties and microstructure that served as a fundamental and more practical basis for describing the hydraulic conductivity of the lime-treated cubitermes sp termite mound soil. The results show that changes in particle size lead to a decrease in dry density and linear swelling. Permeability is strongly correlated with particle size distribution and compaction. Permeability increases up to the lime fixation point obtained at 6% of the lime content. Compaction for micropore reduction in treated soil is higher than in raw soil. The treated soil has a denser internal structure with agglomerations of dispersed clay particles. The increase in compaction energy reduces macropores and permeability, and the soil microstructure becomes homogeneous. Natural soil is highly impermeable, and soil-lime mixes are among the least draining materials. Higher values of hydraulic conductivity were obtained as a function of time. Soil and mixtures can be used in civil engineering works (earthworks). Correlations between hydraulic conductivity and particle size fractions are polylinear fits with R2 (0.962-0.993) and the Slogistic1 model with χ²(2.06E-15) for the mean silt fraction. This study is decisive for predicting hydraulic conductivity from the geotechnical properties of the soil, by solving the mathematical expressions of the models used.

Pituitary apoplexy (PA) is a rare clinical situation caused by pituitary infarction with or without haemorrhage. Although it is usually spontaneous, dopaminergic agonists (DA) are known to be predisposing factors, particularly Bromocriptine, more rarely Cabergoline. We report the case of a 31-years-old patient with a microprolactinoma who developed acute visual acuity loss due to pituitary apoplexy 5 months after taking Cabergoline. The evolution was marked by a considerable improvement of the visual state. Pituitary apoplexy is a rare situation. Often reported with Bromocriptine, PA can also occur with Cabergoline. Due to the high mortality and morbidity of apoplexy, it should be borne in mind that close monitoring is necessary when treatment with DA is prescribed and the patient should be informed of this risk. Although DA precipitate risk, treatment can be continued for hormonal and anti-tumour remission.

Background: Over the last 10-15 years, dengue fever (DF) and dengue hemorrhagic fever (DHF) have become the leading causes of hospitalization and death among both children and adult. Carica papaya leaves juice is said to increase platelet count, reduce complication and duration of Hospital stay. Objective: This study aimed to determine the effect of Carica papaya leaf juice on duration of Hospital stay in child patients with DF and DHF. Methods: This randomized controlled trial was conducted among 77 children with DF and DHF. Patients were purposively selected from the inpatient department of Dhaka Shishu hospital from July 2018 to December 2019. Patients were randomly allocated in group A and group B. Group A patients received standard treatment along with a bottle containing C. papaya leaves juice 10 ml single morning dose 15 minutes after breakfast for three consecutive days and group B patients received only standard management as per the National Guideline for Clinical Management of Dengue Syndrome, 2018. Three patients in group A and two patients in group B dropped out from the study. Results: There was no significant difference between the groups regarding age, sex, mean duration, type and severity of fever between the groups (p>.05). In group A, the mean platelet count increased from 105000.00/ mL to 152428.57/mL after 48 hours and it reached to 212228.57/mL at 72hrs. In group B, the mean platelet count initially decreased from 129485.71/ mL to 91114.28/mL after 48 hours and then it increased to 96142.85/mL at 72 hours. There was highly significant statistical difference between group A and group B at 48 hours and at 72 hours regarding mean platelet count as p <0.001. Haematocrit values become significantly normal in group A than group B by 72 hours and p value ˂0.05. There was highly significant statistical difference between group A and group B regarding mean hospital stay as p <0.001. Conclusion: Administration of Carica papaya leaf juice shorten hospitalization in patients with Dengue fever and Dengue haemorrhagic fever.

Introduction: Open appendectomy (OA) and laparoscopic appendectomy (LA) are the choices of treatment for acute appendicitis. However, laparoscopic approach is emerging for the benefits it provides, but it also sometimes may has some drawbacks like OA including fistula. Objective: This retrospective study aims to investigate the management of fistula in 50 post appendicectomy fistula patients. Methods: A retrospective study was done at MH Samorita Medical College & Hospital, Hi-Tech Surgicare Hospital & Piles Centre, Savar Specialized Hospital and Lab Zone Hospital Savar, Bangladesh during January 2019 to December 2023 from January 2019 to December 2023, among the patients who had underwent laparoscopic appendicectomy and open appendicectomy. The total study population was 50, among which 33 (66%) patients were in open appendectomy and 17 (34%) were in laparoscopic appendectomy. The patients’ age group included 10 years to 50 years of both male and female patients. P< 0.005 was considered significant in this study. Results: Out of total study population, 33 were from OA (66%) and 17 were from LA (34%) group. Most of the study patients were male, aged 21-30 years age group. Fistulogram found to be the commonly use method to diagnose fistula. Tuberculosis was found to be the frequent cause of post appendicectomy fistula. Conclusion: Post appendicectomy seems to have different outcomes with some adverse impact, fistula is one of them. The present study finds that the chances of post appendicectomy fistula is less in LA group compared to OA. Proper study and better investigation may bring this to null with time.

Background: Pneumatic dilation (PD) is often presented today as a “short term” treatment for achalasia but, in truth, it can last for years. our study aims to determine the short and long-term efficacy of pneumatic dilatation on clinical remission in a treatment-naïve achalasia patient. Materials and Methods: A single center retrospective, descriptive and analytical study conducted between January 2007 and September 2022. Treatment naïve patients with manometric diagnosis of primary achalasia (subtype I and II) were included. We evaluated the clinical outcomes; single vs multiple PD, complications, and estimated duration of effect. Results: 121 patients were included, (mean age 42,2±14,5; 53,8% male), 88,4% (n=104) underwent 2 PD and 11,6% (n=17) underwent 3 PD, 23,1% (n=28) needed repeated PD at one year, The PD procedure was completed without major complications in all patients. Patients with subtype II had a better response to PD than subtype I(p=0,003). In the long-term follow up (median time: 50 months), the mean Eckardt score was 2.2. A subsequent 35 mm dilatation was associated with long-term clinical remission than an initial dilatation with 35 mm.(p=0.003). On univariate analysis, the non-responders more often was male gender, had age< 40 years (p=0.0006), and had high baseline LESP (lower esophageal sphincter pressure>50 mmHg), p=0.004). On multivariate analysis only age<or= 40 years (p=0.02) was associated with poor outcome. Conclusion: PD is an effective, durable and safe treatment for achalasia. A graded-protocol PD starting with a 30 mm dilation applied in the appropriate achalasia subtypes was shown to be a highly effective approach, in both the short- and long-term. Age<40 years, male patients and hight LESP have poorer outcomes following PD.
