A series of some solid transition metal complexes of some mannich bases, substituted N-(1-piperazino) benzamide with Ca (II), Cu (II) and Zn (II) complexes in the presence of ice cold condition. The newly synthesized compounds were characterized on the basis of elemental analysis, IR, 1H NMR and mass spectra. All the synthesized compounds were tested for their anti-inflammatory, anti nociceptive, antibacterial activities against Gram + and Gram – bacteria. The synthesized compounds were screened for inflammatory activity via standard approaches, and they have shown positive anti -inflammatory activity.

This study compared the effect of task-based and systematic instruction on L2 learners’ productive vocabulary retention. The participants of the study were 73 Iranian female intermediate EFL learners who were divided into a split information task group (n=25), a shared information task group (n=25), and a systematic instruction group (n =23). Before treatment all the participants were given a fill in the blanks pretest to check their vocabulary production ability. Then the new words were taught to the three groups. Two weeks after the end of the treatment, the vocabulary productive delayed posttest was administrated. The results showed that task-based instruction improved the learners’ productive vocabulary retention significantly more than systematic instruction providing that the task type was taken into account. The participants under task-based instruction could follow some principles (Thornburg, 2002) essential for moving the new words from short-term store into permanent long-term memory such as repetition, retrieval, pacing, active Use, cognitive depth, personal organizing, and attention, and as a result, they could have more successful performance in the vocabulary productive delayed posttest than the systematic instruction group.

The present study was carried on to investigate the relationship between EFL learners’ behavioral patterns in learner/ teacher-centered classes and the proficiency level of the learners. It is believed that as one moves up from one level of proficiency to another, classroom interaction becomes less teacher-centered and learners have a bigger share in classroom discourse. The participants of the present study were 180 female students of nine EFL classes majoring in ‘Interchange 1’, ‘Interchange 3’, and ‘Passages 2’ books at Sadr English language institute. In each of the classes under study, a total of sixty minutes of classroom interaction was tape-recorded, thirty minutes of which was randomly chosen for the sake of the present study. The tape-recorded data were later analyzed based on Brown’s Interaction Analysis System (BIAS). A post hoc sheffe test was conducted to shed light on the differences. It was revealed that learners showed the most responding behavior at the advanced-level classes, and they showed less responding behavior at the intermediate classes, and they showed still less responding behavior at the elementary level classes. The results also showed that teachers had the most frequency of talking at the elementary level classes, and they had the least frequency of talking at the advanced level classes. Teacher talk at the intermediate classes was in between.

Although transportation is one of the basic means of measuring development, in a country, in most developing countries, rural transportation is inadequate. The study discusses the importance of the role of transportation in development with respect to rural settlement areas in rural areas of Plateau State in Nigeria. The approach was based on field observation and the interpretation of data collected to inform the role transportation plays in the transportation of agricultural produce. Roads conditions were assessed through respondents and how they ranked the conditions of roads in selected rural settlement areas in Plateau State. This was preceded by analysing sets of data from a desktop survey to put the study in context. The transportation problems faced by rural dwellers in Plateau State impacts negatively on their quality of life i.e. high cost, inadequate maintenance of roads. In spite of these challenges rural dwellers cannot do without transporting their produce to market centers. However, the challenges the challenge are the costs, the road conditions and inadequate provision for transportation of agricultural produce from rural areas to market centers.

The main goal of this research is to study the relationship between Business Intelligence and productivity in the companies, manufacturer of pressure vessels, located in Amol – Mazandaran. The other goal of this research is to prioritize the factors of Business Intelligence using AHP approach. The population of the research consists of top, middle, and operating managers, that out of a group of 90 people, 76 of them have been selected, based on the Morgan Sample Capacity Estimating Table, as the sample of the study. For collecting data, two questionnaires of Business Intelligence and productivity have been used. At first, to analyze the research data, the efficiency of each unit has been measured by the help of DEA technique. Then by the help of descriptive and inferential statistics, the hypothesis of the research have been studied and finally the factors of Business Intelligence have been prioritized by the AHP approach. According to the results of DEA technique, units that have more resources will act in a weaker level in terms of efficiency. The result of testing the hypothesis showed that there was a positive and meaningful relationship between Individual (P=0.006), system quality (P=0.009), individual learning (P=0.043), competitive performance(P=0.01), and productivity. There is also a positive and meaningful relationship between Business Intelligence and productivity (P=0.02). Among the factors of Business Intelligence, the competitive performance is the most important factor in enhancing productivity, and the Mental Model Maintenance is the least one.

The main source of the Nigerian energy generation is the non-renewable source (which includes the burning of Fossil fuels). Fossil fuels (Coal, Natural gas and Petroleum) are being consumed and certain chemical compounds such as CO2 are emitted into the atmosphere. The objective of this research is to examine the trend of CO2 emission from the consumption of Fossil fuels and fitting a model for monitoring the process. Vector Autoregressive Model (VAR) was developed. The Portmanteau test for serial correlation and the Wald test for Granger-causality were carried out. VAR (1) fit the data. The Portmanteau test showed that error term are serially uncorrelated. The Wald test, showed that CO2 emission from Coal Granger-cause emission from Natural gas and Petroleum and vice-versa. The emission from Natural gas does not Granger-cause emission from Petroleum.

Businesses calculate the life time value of customers and extrapolate their future profits. Higher revenues are guaranteed only when the customer keeps a business relationship with the business for entire his or her life. Given the small sample population of micro businesses are keen to retain their customers for longevity of their profits as against a situation where a customer switches before his life time value ceases. This study indicates that micro businesses are keeping good customer relationship with its customers via word-of-mouth marketing which is considered as instrumental for success of majority of micro business as it serves as a credibility filter and is carried out independently by the customers. At the same time, this finding does not indicate any clear picture as to which form of marketing is doing better. Because our empirical analysis indicates that majority of micro business are dormant in the domain of social media marketing.
