No full textAn incubator is a device that is used to turn the
fertile eggs hatching successfully at suitable
environmental conditions by regulating the
temperature and humidity of the enclosure. To
meet the high demand of poultry production
artificial egg hatching is needed. So temperature
controls are an important factor for the incubation
process. The source of power in an incubator is
electrical energy. Energy is limited on earth. So
proper use of energy is an important factor. By
controlling
the temperature and humidity
efficiently we can reduce the electrical energy
consumption. In this paper, we have discussed
energy-saving techniques in hatching incubators
which can save energy. The possibility of hatching
egg is about 35-40° centigrade but the optimum
temperature should be kept at 37.5° centigrade for
21 days and Below 35° centigrade and above
40.5° centigrade no embryo can be survived for
hatching. Cooling eggs for short periods says 30
40 minutes out of 24 hours regularly with no
harmful effect during incubation and probably
profit. So to reduce energy consumption we
introduced a power-saving mood that keeps the
system shut off for 15-20 minutes within 24 hours
during incubation. Using the inverter, we have
simulated the backup system which has improved
the temperature rise time and settling time
compared to the conventional egg incubator.
Calculation shows that this system is energy
efficient

A study on the factors influencing consumers’ re-purchases intention towards eco friendly packaged FMCGS with the mediating role of customer satisfaction
Get PDFPurpose: The sustainability of packaging should be enhanced by reducing the amount
of materials used and incorporating recycled components, given that packaging
significantly contributes to pollution. In the fast-moving consumer goods (FMCG)
sector, businesses face increasing pressure to adopt environmentally friendly
strategies. This research seeks to identify the factors influencing repurchase intentions,
with customer satisfaction serving as a mediating factor, specifically among
consumers in the Central Province of Sri Lanka.
Design/methodology/approach: A comprehensive review of the literature identified
attitude, environmental concern, willingness to pay, and personal norms as
independent variables, while consumers' repurchase intention was treated as the
dependent variable. Additionally, customer satisfaction was employed as a mediating
variable. The study followed a deductive approach, Data were collected through
structured questionnaires distributed to 384 consumers in the Central Province, using
convenience sampling technique. Hypotheses were tested using correlation analysis,
multiple linear regression analysis, and the Sobel test, with IBM SPSS 27 software
employed for data analysis.
Findings: The results highlighted the significant influence of attitude, personal norms,
environmental concern, and willingness to pay on consumers repurchase intentions
towards eco-friendly packaged FMCGs. Customer satisfaction partially mediated the
relationship between attitude, personal norms, and environmental concern and there
was no mediation between willingness to pay and repurchase intention.
Practical implications: These findings have important implications for marketers,
government policymakers, and packaging designers, encouraging them to implement
measures that enhance repurchase intentions for eco-friendly packaged FMCGs in Sri
Lanka.
Originality value: In Sri Lankan context, there were no previous researches that had
explored the use of customer satisfaction as a mediator in the FMCG sector
The sources of stock market volatility: a study on the Colombo stock exchange
No full textPurpose: This study investigates internal/own shock in the domestic market and three external volatility spillovers from India, the UK, and the USA to the Sri Lanka stock market. Need for the Study: The external market’s internal/own shocks and volatility spillovers influence portfolio choices in domestic stock market returns. Hence, it is required to investigate the internal shock in the domestic market and the external volatility spillovers from other countries.
Methodology: This study employs a quantitative method using ARMA(1,1)-GARCH(1,1) model. All Share Price Index (ASPI) is the proxy for the Colombo Stock Exchange (CSE) stock return. It uses daily time-series data from 1st April 2010 to 21st June 2023.
Findings: The findings revealed that internal/own and external shocks substantially impact the stock price volatility in CSE. Significant volatility clusters and persistence with extended memory in ASPI confirm internal/own shock in the market. Furthermore, CSE receives significant volatility shock from the USA, confirming external shock. This study’s findings highlight the importance of considering internal and external shocks in portfolio decision-making. Practical Implications: Understanding the influence of internal shocks helps investors manage their portfolios and adapt to market volatility. Recognising significant volatility spillovers from external markets, especially the USA, informs diversification strategies. From a policy standpoint, the study emphasises the need for robust regulations and risk management measures to address shocks in domestic and global markets. This study adds value to the literature by assessing the sources of volatility shocks in the CSE, employing the ARMA-GARCH, a sophisticated econometrics model, to capture stock returns volatility, enhancing understanding of the CSE’s volatility dynamics
Study of meat quality parameters of broiler chicken under halal and kosher methods
Get PDFChicken meat is the most popular protein dish in Sri Lanka. The Halal
Method and Kosher Method are the two prominent slaughtering methods
practiced all over the world. The objective of this study is to critically
compare broiler chicken undergoing both the Halal Method and Kosher
Method. Breed of Arbor Acres plus Broilers were collected from broiler
farms and slaughtered at the age of 38+ days with an average weight of
2.05kg. The slaughtering processes were done at Nelna Processing Plant,
Meethirigala. After the slaughtering process, proximate analysis for Crude
protein content, crude fat content, Moisture content and Ash content was
conducted at the Department of Biosystems Technology of South Eastern
University of Sri Lanka. Data were analyzed using the Minitab 20 edition.
According to the proximate analysis results, there was no significant
difference between the results of Crude protein content, Crude fat content,
Moisture content and Ash content (p > 0.05). According to the results, there
is no significant difference between two methods for Crude protein content,
Crude fat content, Moisture content and Ash content. Furthermore, there was
no significant difference between the proximate compounds. This study
warrants a more detailed study to be conducted to compare both Halal
Method and Kosher Methods
Stock market volatility and the COVID-19 pandemic in Sri Lanka
No full textPurpose: This chapter examines the effect of COVID-19 on the stock market volatility (SMV) in the Colombo Stock Exchange (CSE), Sri Lanka.
Need for the Study: The study is necessary to understand investor behaviour, market efficiency, and risk management strategies during a global crisis.
Methodology: Utilising daily All Share Price Index (ASPI) data from 2 January 2018 to 31 August 2021, the data are divided into subsamples corresponding to the pre-pandemic period, the pandemic period, and distinct waves of the pandemic. The impact of the pandemic is investigated using the Mann–Whitney U test, the Kruskal–Wallis test, and the Exponential Generalised Autoregressive Conditional Heteroscedasticity (EGARCH) model.
Findings: The pandemic considerably affected CSE – the Mann–Whitney U test produced different market returns during the pre-COVID and COVID eras. The Kruskal–Wallis test improved performance during COVID-19 but did not continue to do so across COVID-19 waves. The EGARCH model detected increased volatility and risk during the first wave, but the second and third waves outperformed the first. COVID-19 had a minimal overall effect on CSE market results. GARCH and Autoregressive Conditional Heteroskedasticity (ARCH) models identified long-term variance memory and volatility clustering. The News Impact Curve (NIC) showed that negative news had a more significant impact on market return volatility than positive news, even if the asymmetric term was not statistically significant.
Practical Implications: This study offers significant insight into how Sri Lanka’s SMV is affected by COVID-19. The findings help create efficient mitigation strategies to mitigate the negative consequences of future events
