Radish (Raphanus sativus L.) is a major root vegetable crop in Nepal. Organic manures are an indispensable substitute for the highly toxic inorganic fertilizers. A research experiment was conducted at the horticulture farm of Institute of Agriculture and Animal Science (IAAS), Paklihawa campus, Rupandehi, Nepal to investigate the effect of different organic manures on the growth, yield, and quality of Tokinashi variety of late-season radish. The experiment was conducted in a randomized complete block design (RCBD) with three replications. The seven different treatments were farm yard manure (FYM) (30 t ha-1), poultry manure (20 t ha-1), FYM (15 t ha-1) + poultry manure (10 t ha-1), FYM (15 t ha-1) + vermicompost (2.5 t ha-1), vermicompost (5 t ha-1), FYM (15 t ha-1) + Bone meal (5 t ha-1), and control (without use of organic manures). Poultry manure was observed significant effect on the growth and yield attributes of radish. The effect of poultry manure over other treatments, viz. plant height (31.17 cm), number of leaves (20.53), shoot length (29.68 cm), crown spread (51.4 cm), root length (28.6 cm), root diameter (10.81 cm), average root weight (130.2 gm), average shoot weight (71 gm), root dry weight (125.33 gm), harvest index (64.85%), shoot yield per hectare (16.22 t ha-1), biological yield per hectare (50.3 t ha-1), root yield per hectare (23.87 t ha-1), and total soluble solid (1.13 0 Brix) were recorded maximum at harvest (77 days after sowing). The ascorbic acid was recorded maximum (0.181 mg ml-1) in vermicompost. It can be concluded that poultry manure can be used for higher yield for late-season radish cultivation under Rupandehi, Terai condition of Nepal.

This study samples the Perception of Secondary School Students on the quality of PGDE Teachers produced through National Teachers Institute (NTI) of Nigeria program. The study was guided by four hypothesis and three research questions. Stratified random sampling technique was adopted in selecting a sample of 100 Secondary School Students from National Mathematical Centre International Model Science Academy and Government Secondary School Hajj camp. Questionaire containing sixteen items was used to elicit information. The data collected was analysed. The findings were PGDE Teachers produced through NTI program are competent in the general studies aspect of education, competent in their area of specialisation and in the professional aspect of teacher education. Some gray areas were identified in the general studies aspect of education and recommendations were made on how to improve NTI program generally.

Die-drawing, also known as solid phase orientation, is a technique used to enhance the mechanical properties of polymers for non-medical applications [1]. Arterius has adapted and optimised this technology to manufacture state-of-the-art bioresorbable polymeric scaffolds (stents) based on polylactic acid (PLA) for vascular and non-vascular applications. The mechanical properties of the polymer are improved by orientating the polymer chains and introducing crystallinity to the polymer. As the PLA polymer is drawn over a mandrel and through a die, close to the glass transition temperature (Tg > 55 °C), the polymer chains align, gradually increasing orientation with the bi-axial draw, thus promoting significantly improved mechanical properties. In-house testing of the die-drawn tubing compared to the extruded tubing showed an increase in tensile modulus up to 79.7%, yield strength increases of up to 121.5%, ultimate tensile strength increases of up to 267.9% and elongation at break increase of up to 1,022.8%. The die-drawing process also introduces crystallinity into the PLLA tubing, initially the amorphous extruded tube has a crystallinity of around 1.3% which increased to around 40% crystallinity after the die-drawn process. Another attribute of the orientated polymer tubing is the radial strength it provides to the scaffold once it has been laser cut into an innovative closed-cell design, which is comparable to market-leading metallic stents.
