Abstract

Okro (Abelmoschus esculentus) was grown in the field and green house and fertilized with organic‐based fertilizer (OBF), organic and chemical fertilizers. Okro soups produced from the okro fruits harvested from the various fertilizers treatments were subjected to sensory evaluation tests. Application of varying rates of organic fertilizers on the greenhouse okro plants showed that 10 tonnes per hectare of organic fertilizer led to significant increases in microbial activities in the root zone and it also gave the highest pod yield. In the sensory evaluation test of organically grown okro, panelists preferred organically grown okro soup to the chemically grown variant when they assessed the colour, taste, texture, flavour and drawness. Organically grown okro enjoyed more acceptability than tthe chemically grown. In the field trial,no significant effects of all the treatments were found on some growth parameters assessed. However, application of 5t/ha of OBF led to significant increases in the number of okro pods.

Abstract

Purpose

Kaolin (hydrated aluminum silicate) is one of few minerals that are found in nature in a relatively pure state which is abundant in many places of the world. In this research, a simple chemical treatment using traces of ammonium molybdate was carried out to enhance the anticorrosive properties of kaolin.

Design/methodology/approach

The steps of treatment of kaolin at 1,000°C were estimated. Characterization of three different combinations of aluminum oxide with iron oxide were studied using spectroscopic methods of analysis via X‐ray diffraction (XRD), transmission and scanning electron microscopy (TEM and SEM). Also, evaluation of the prepared pigments using (oil absorption, specific gravity, water‐soluble matter, and pH) international standard testing methods were estimated. Then these prepared pigments were incorporated in anticorrosive paint formulations based on medium oil alkyd resin as a binder, the physico‐mechanical and anticorrosive properties of paint films were detected by testing them in 3.5 percent NaCl solution for 28 days.

Findings

Introduction of small amounts of ammonium molybdate in kaolin promoted its physico‐mechanical and anticorrosive properties. Although, this process of treatment is economically feasible, treated kaolin can replace expensive commercial pigments found in markets with an almost near quality to their performance.

Originality/value

Treated kaolin can be applied in many industries beside pigment manufacture, and paint formulations, it can be applied as reinforcing filler in rubber, plastics, and ceramic composites. Also it is applied in paper filling, paper coatings, and electrical insulation.

Abstract

Purpose

PE and DCF are two popular valuation methodologies used by analysts to derive target price forecasts while performing equity research. Recent studies in developed markets show that analysts using sophisticated models like DCF produce more accurate target price forecasts as compared to heuristics driven models like PE. This study investigates if analysts using DCF outperform analysts using PE in an emerging market institutional set up.

Design/methodology/approach

An in-depth analysis of 392 equity research reports is conducted to understand the dominant valuation model used by analysts to derive target price forecasts. Research reports with clear mention of valuation methodology (PE or DCF) to derive target price forecast are used for the purpose of performing this analysis. Multivariate OLS and logit regression analysis has been conducted to investigate if analysts using DCF outperform analysts using PE to derive target price forecasts.

Findings

The study finds that analysts using PE produce significantly better short-term results than analysts using DCF i.e. when target price accuracy is measured anytime during forecast horizon of 12 months. However, there is no significant difference in target price performance or target price forecast error of PE and DCF model when analyst performance is measured at the end of the forecast horizon.

Practical implications

In contrast to results from developed markets, this study does not find evidence of superior target price performance of DCF. On the contrary, results suggest that PE outperforms DCF on the short-term measure of target price accuracy. This study shows that PE model which captures market moods and sentiments effectively is more suitable in dynamic, emerging markets like India.

Originality/value

Past studies have explored the performance of PE and DCF in developed markets and this study provides fresh empirical evidence on target price accuracy of valuation model from an emerging market like India. The superior short-term target price performance of PE as compared to DCF may be relevant exclusively in emerging markets like India.

Abstract

I am thankful to many colleagues and institutions for their assistance in bringing up this important work to its fruition for publication. As a most comprehensive work on the epistemological foundations of a theory of Islamic economics and finance, this work required a lot of initiative to get it up to the publication level. It was very difficult to bring the entire subject matter and contents of this book to a fair degree of understanding among colleagues. The impediment in this direction was the prevalent subservience of Islamic scholarship to mainstream economic theory that has its own epistemological leaning, which has already received serious criticism from the highest levels of thought. But these critical examinations along with the Islamic epistemological scholarship have not seeped into intellection. Islamic economics and finance as a subject area leaned and slumbered in the bosom of a disappearing linage of neoliberal paradigm. It never had the chance to mature and become an original contributor in the absence of intellectual consciousness that must establish the domain of high thought. The present book is a criticism of that uncritical and epistemologically barren intellection in Islamic economics and finance. While this book takes a bold and original approach to the epistemological foundations of Islamic economics and finance, conceptually, analytically, and empirically, it seriously rejects the prevalent scholarship on intellectual grounds.

Abstract

Purpose

The aim of this paper is to undertake analysis and comparison of the closed‐loop and sensorless control systems sensitivity to the broken rotor for diagnostic purposes. For the same vector control system induction motor drive analysis concerning operation with the asymmetric motor, broken rotor fault handling and operation were investigated. Reliability, range of stable operation, fault symptoms and application of diagnosis methods based on control system variables utilization was analyzed.

Design/methodology/approach

Induction motor drive vector control system synthesis was applied using the multiscalar variables of the machine model with nonlinear feedback linearization applied to use classical cascaded PI controllers for the speed‐torque and flux decoupled control. Speed observer was applied for the rotor flux and rotor speed estimation for the sensorless control system synthesis.

Findings

Relative sensitivity of the state and control system variables to broken rotor fault based on experimental results for the closed‐loop and sensorless control systems is presented and compared. Drawbacks of using the MCSA analysis for the rotor fault diagnosis in the closed‐loop and sensorless control systems are pointed. Advantages and drawbacks of the state space estimators filtering characteristics in the sensorless control system are described.

Practical implications

Asymmetric IM motor drive handling and diagnosis. Broken rotor range diagnosis inconsistency using the popular MCSA method should be considered in the closed‐loop and sensorless control system of the induction motor drive. Depending on the IM motor drive application and the operation requirements the results can be used for asymmetric machine proper handling, choosing proper control system structure and control system variables for rotor fault early diagnosis.

Originality/value

Sensitivity of the state and control system variables to broken rotor fault based on experimental results for the closed‐loop and sensorless control systems is presented, which implies motor handling procedures and fault diagnosis.

Abstract

The field of intellectual capital is at a crossroads. To move through the crossroads and to the next stage both practitioners and academics must substantially demonstrate the relevance of intellectual capital as a working discipline useful to achieve strategic goals and to improve levels of performance. While the field has generated a growing body of knowledge and practice over the last two decades, there is a need for both a great leap in how value can be generated and captured using an intellectual capital perspective, as well as acknowledging that there are multiple ways of knowing and different models for intellectual capital exchange. Much of this new development will come from an expanded, continuing dialogue between practitioners and academics.
