The LTE broadband evolved from an earlier Third Generation Partnership Project system which is known as the Universal Mobile Telecommunication System (UMTS), which evolved from the Global System for Mobile Communications (GSM). The network architecture of this system has been designed with the aim to support a packet-switched traffic with seamless mobility and great quality of service. The main goal of the LTE is to provide a high data rate with low latency and a packet optimized radio access technology that supports deployment of bandwidth. Hence, this study is based on the evaluation of the LTE network in the south-west region of Nigeria. This study evaluates the LTE network strength in the South-West region of Nigeria. Questionnaires were administered among users in these areas randomly. Thereafter, data were analyzed and research questions were answered from the analyzed results. The results showed that 9Mobile and MTN has the best quality of service of LTE network in South-West, Nigeria, also that the LTE network has not really been active in Osun and Ekiti states.

The study examined the impact of performance based budget on projects effectiveness, quality and sustainability in Fako and Meme Divisions of the South West Region, Cameroon. Three specific objectives were formulated to guide this study. The objectives investigated the impact of performance based budget on the effectiveness of projects, the impact of performance based budget on the quality of projects and the impact of performance based budget on the sustainability of projects. Ex-post facto research design was used for this study. The sample of this study was made up 420 respondents comprising of service providers, beneficiaries of the projects and staff of the Regional Delegation of Water and Energy and the Regional Delegation of Public Works in Fako and Meme Divisions. A well validated structured questionnaire was used for data collection. Data collected were analyzed using descriptive statistics and dependent t-test. Findings revealed that there exist a significant difference in the quality of roads, water and electricity projects before and after implementation of performance based budget with the quality of roads higher after the full implementation than before the implementation of PBB. There exist a significant difference in the effectiveness of road, water and electricity projects before and after implementation of water projects, and there exist a significant difference in the sustainability of road, water and electricity projects before and after implementation of performance based budget. The study recommended that the effectiveness of the budgetary system should be improved so that the quality and sustainability of projects will be obtained.  Moreover, good budget begets good results.

The paper concentrates on the measurement of the total factor productivity of dairy farms in the south-west region of Bangladesh. The study used stochastic frontier approach for analyzing the technical efficiency of the dairy farms. Here, seventy dairy farms are considered as a sample. The data reveals that the number of labor and the quantity of food are statistically significant at a 1 percent level of significance.The data also manifests that numerous farm-specific characteristics, i.e. farm size, farmer’s age, and amount of credit are statistically significant at 1 percent, 10 percent, and 10 percent respectively. The range of technical efficiency for the farms varies from 26 percent (minimum) to 95 percent (maximum) where the mean value is 68 percent for the dairy farms of the south-west region. This implies that an average output of milk production falls 32 percent short of maximum possible level. Hence, there is scope of improvement in this sector. Therefore, to improve the farm productivity government should provide proper training, and medical treatment facilities for the farms so that the animals become healthy. If it is possible to do so then the farm level production frontier will shift upward.

Novel Method

This paper presents a novel method of expressing the quality of service in a mobile telecommunication system when its performance depends on several factors including applied codecs? characteristics (voice quality and data flow rate) and telecommunications traffic service possibilities. The influence of these factors is unified in one variable - quality of service measure. The proposed method is especially applicable in the cases when two-dimensional systems are analyzed - for example when two codecs with different flow rate and different achievable connection quality are used in a system. As an example, we also studied system with full-rate or mixed full-rate and half-rate codec implementation depending on the offered traffic. The system performances - mean dataflow and mean connection quality as a function of offered traffic are presented graphically and also expressed quantitatively by the novel quality of service measure. The systems with different number of available traffic channels may be compared on the base of this novel evaluation value such that the system with the highest value is the most suitable one for the concrete situation. In this way mobile system design is simplified to the great extent. The developed model is applicable generally for mobile telephony systems defining, but in this paper we studied its implementation for Global System for Mobile communications.

Rock Dust

The purpose of this work is to analyze lettuce cultivars different responses to environmental adaptability and rock dust concentrations in agroclimatic conditions in the south-west region of Goiás state. The work was conducted in the county of Mineiros, Goiás. The experimental area soil’s was classified as quartzarenic NEOSOL. In experiment number 1, was used experimental design in random blocks in factorial 5 × 2, corresponding to five rock dust concentrations (0, 100, 200, 300 and 400 kg ha-1), in two lettuce cultivars of Crespa and Americana lettuce. In experiment number 2 was applied experimental design in randomized blocks, which were constituted by 7 lettuce cultivars (Hanson, Simpson S. Preta, Baba de Verão, Maravilha de Inverno, Grandes Lagos, Crespa Palmas, and 4 Estação). The data results were analyzed 45 days after seeds transplant. The results were submitted to variance analysis and Turkey’s regression and test at a 5% probability. The 400 kg ha-1 rock dust dose didn’t have any effects in lettuce cultivars Crespa and Americana, once that, rock dust nutrients mineralization occurs very slowly, not interfering in the lettuce first cycle. 4 Estação cultivar presented good environmental adaptability to Goiás south-west agroclimatic conditions, more specifically in Mineiros, where it is recommended lettuce cultivation in summer-fall.
