Foliage preservatives for vase life extension of two dieffenbachia species
(2010) Thambugala, S.; Abeywickrama, K.P.; Karunarathna, S.
Cut foliage of Dieffenbachia maculata and Dieffenbachia amoena were subjected to continuous treatment with several foliage preservatives and export simulation. The preservatives used were 1.75% of sodium hypochlorite, 5% vinegar and VimTM dish washing detergent. Tap water without any added chemicals was used as the control. The highest vase life of 45.1 days was observed in D. maculata cut foliage when subjected to continuous treatment with tap water. Cut foliage of D. maculata subjected to continuous treatment with 0.016% (v/v) dish washing detergent (Vim™) solution and 0.016% (v/v) sodium hypochlorite (NaOCl) and subjected to export simulation for two days at 12-140 C and 85-90% relative humidity (RH), had relatively longer vase life of 38.9 days and 37 days respectively. Cut foliage of D. amoena had the longest vase life of 21 days when subjected to 0.016% NaOCl treatment and export simulation. NaOCl which is considered as a biocide and mild vinegar solution which is acidic inhibited the bacterial growth in vase solutions increasing the vase life of cut foliage. A Bacillus sp. and a Staphylococcus sp. were associated with vase solutions of D. maculata and D. amoena cut foliage. Treatment with NaOCl and VimTM satisfactorily extended the vase life of cut foliage of D. amoena and D. maculata respectively and could be recommended as preservatives for use during export.
IMPACT ON STAFF MOVING FROM OPENARC SYSTEMS MANAGEMENT (PVT) LTD
(2015) Karunarathna, S.
High Employee moment is detrimental to the success of any business especially in organizations where their success and level of productivity solely depends on their employees. This study identifies the factors responsible for moment intention of workers in a software company. It also explored and identified the relationship between moment intent, pay, job satisfaction and relationship with supervisors as empirical literature suggests its influence on employee moment. The findings identified that pay level, delayed wage, length of break, benefits, and lack of recognition had a negative impact on moment intention while factors such as motivation, Remuneration, work environment and Management style was found to have little or no effect on the moment of workers. It further identified the relationship between age and moment intention as negative. Based on the findings, recommendations were proposed to address the most important factor identified.
