On modeling the causes of presbyopia Weale (2000) presents a theoretical analysis to support his contention for a multifactorial explanation for presbyopia. He suggests that the model supports the notion that the accelerated loss of accommodation relative to other physiological indicators of age is due to the combined effect of normal age related changes in the component elements of the accommo...

The study examined the relationship between Budget deficit and Trade deficit for the economy of Pakistan. Time series data was used from the period 1972 to 2011. Augmented Dickey Fuller Test used to check the stationary of the variables and found that all variables were stationary at first difference. Johansen Co-integration used to find the long relationship and found that budget deficit has p...

This paper examines the relationships among Hangseng index and its related derivatives in a bear market. The Johansen Co-integration and vector error correction model are used to analyze the relationships between markets. The main results are as follows: 1) The lead-lag relationships show that Hangseng index futures and option markets play a more important price discovery role; 2) The pricing e...

The positive relationship between inflation and relative price variability has been taken as a proven case, but recent evidence casts doubt on the verdict. This paper shows that theory can support positive or negative relationships, while past empirical evidence may have been contaminated by aggregation bias and our measures of price dispersion and inflation. We re-examine the empirical evidenc...

This study aims investigate the short- and long-run causal relationship between foreign trade economic growth in Libya over period of 1990 - 2017. employs Johansen co-integration test, error correction model (VECM), Wald test to meet objective study. The variables utilised this are gross domestic product (GDP) rate, exports imports; data is extracted from various sources such as Libyan Central ...

The present study investigates the cointegration relationships among crude oil price, domestic gold price and selected financial variables (exchange rates and stock price indices) in India. Increasing crude oil prices will increase the production costs which will affect cash flow and will decrease stock prices. Investors are showing fewer concerns in the stock markets and investing in yellow me...

DNA in eukaryotes is wrapped around a histone octamer containing H2A, H2B, H3, and H4, forming a nucleosome, which is the fundamental unit of chromatin. Posttranslational modifications of these histones play critical roles in genome function, including the regulation of transcription and maintenance of genome integrity (Jenuwein and Allis, 2001; Kouzarides, 2007). However, little is known about...

Soil thermal conductivity (λ) is an important property that crucial for surface energy balance and water studies. 1602 measured soil values representing 189 soils were used to evaluate five empirical models (i.e., de Vries (1963) model (de 1963), Campbell (1985) (Campbell1985), Johansen (1975) (Johansen 1975), Côté Konrad (2005) (Côté 2005), Lu et al. (2007) (Lu 2007)) seven machine learning (M...

The study aims to analyse the long-term relationship between GDP and employment during 2000Q1-2018Q4. relation is important for Turkey who has problems with creation capacity of growth. However, high growth performance 2000s ratios have well remained below OECD averages. Employment elasticity 0.15 2004Q1-2018Q4 period Engle-Granger test. entire much weaker, like 0.04. Johansen tests confirm lon...

Drosophila has long been a favorite model system for studying the relationship between chromatin structure and gene regulation due to the cytological advantages provided by the giant salivary gland polytene chromosomes of third instar larvae. In this tissue the chromosomes undergo many rounds of replication in the absence of cell division giving rise to approximately 1000 copies. The DNA remain...
