Comparison of Different Anesthetic Protocols for Morphometric Measurements of Carp (Cyprinus carpio)

Abstract

Measurement of growth performances in fish is carried out in stressful and unnatural environment. The purpose of the present investigation was to compare the effect of four different water-borne anesthetic agents. The fish (Ave. wt. 400.3±7.12 g) were divided into four groups in the glass tanks (80×48×30 cm) containing 80 L of dechlorinated bore water. For the first group we used clove oil (CO) and anesthetic agents used for other three groups were as follows: second group- lidocaine 1% (LC), III groupisoflourane (IF), IV group-halothane (HT). During experiment, water quality parameters (to, pH, О2, and NO3) were recorded. The desired concentration of anesthetics was established andinduction time, maintenance and recovery time were recorded. In two groups out of four (LC and HT) time of induction was longer approximately with 1 minute and time of recovery was shorter with 30 seconds in comparison with other two groups (CO and IF) where the time for both was 3 minutes. It could be concluded that the anesthetic time for each of the protocols used was about 4-5 minutes and allowed to measure the growth performance. An effective and safe agent is 1% lidocaine used as a water-based anesthetic at 100 mg.L-1. Isoflurane can be used with caution in small carp because there is a risk of overdose. We recommend the anesthetic clove oil protocol.

The Analysis of Production and Culling Rate With Regard to the Profitability in a Dairy Herd

Abstract

As milk prices move away from production costs, dairy farms are under increased pressure to find ways to protect profitability on the farm. Producers have some problems that they can improve. Improve the milk production, produce more milk to sell focused on quality (reduce the amount of high level of somatic cell count). The deterioration of animal health status (lameness, mastitis and different metabolic disorders) can have a serious impact on cow productivity, causing pain and discomfort, production losses and might result in a decision to cull the animal. Improving herd reproductive performance is an important aspect of profitable farm management. The aim of this work is to analyse milk production, reasons of culling and culling rate in different lactation on a dairy cattle farm.

THE USAGE OF POSITAL CANOPEN AGS15 INCLINOMETERS FOR DIAGNOSTIC MONITORING OF SLENDER STRUCTURES

Abstract

This paper concerns the possibility of using AGS15 capacitive inclinometers in the geodetic monitoring of slender structures. The basics of geometric monitoring have been introduced, and the features of inclinometers that can be used in these studies have been described. Main expectations towards them have been formulated. Three tests were conducted: (1) a few days' stability test of readings, (2) the test of inclinations controlled tachimetrically and (3) continuous survey of a physical object. It has been found that in order to obtain satisfactory results it is necessary to correct the readings due to the drift and the effect of temperature. The works conducted as part of described project work are not capable of identifying those indicators. To achieve them there were designed the system that support the acquisition and processing of the measurement and also the collection and transmission of results. In the conclusions authors stated that inclinometers AGS15 can be suitable for monitoring, but the works aimed at improving their performance should be undertaken.

The concept of estimating usable floor area of buildings based on cadastral data

Abstract

Usable floor area is one of the most important spatial attributes of buildings and premises. It is used, for example, to determine the basis for their taxation. Unfortunately, the question of proper determination of usable floor area in Poland has remained problematic for many years, which is closely related to the occurrence of various definitions of usable floor area in the currently binding legal acts. Consequently, usable floor area is not a universal attribute. This means that in certain cases significant discrepancies may occur between the usable floor area of the same structure, determined for different purposes. In addition, despite attempts made to unify the principles for the performance of surveys of building structures and their parts, this requirement still can not be recognized as fully met. Therefore, there is no doubt that the problem of reliability and availability of data defining the usable floor area of buildings is becoming even more important in view of the introduction of the ‘ad valorem’ tax, which has been planned for years. For this reason, this paper proposes a universal, multi-variant method of estimating usable floor area based on geometric and descriptive data of buildings contained in the cadastre. The Authors, taking into account the applicable legal regulations, have considered the possibilities of practical implementation of individual variants of this specific method. They have carried out empirical tests of effectiveness of the proposed approach. They have also defined tasks for which this method of determining the usable floor area of buildings would be particularly useful.

Prospects and challenges of multimedia approach to tourism mapping in Nigeria: a case of wildlife parks mapping

Abstract

Nigeria has a vast array of both natural and cultural tourist attractions. The country’s tourism industry, however, remains grossly underdeveloped, and the tourism resources are largely untapped. Hence, the tourism sector of the economy is yet to contribute significantly to the national Gross Domestic Product (GDP). One major factor that is responsible for the nation’s current lacklustre performance of the tourism sector is the poor state of tourism packaging and promotion, which, amongst other things is caused by the lack of appropriate tourist maps. Tourism mapping is a key component of tourism planning, development, promotion and management. For Nigeria to drastically and significantly improve the fortunes of her tourism sector, the production, circulation and use of accurate, current and comprehensive tourist maps and atlases must be vigorously pursued. To ensure sustainable tourism mapping and in line with global best practices, the country needs to adopt a Geoinformation technology-based, Internet-compatible multimedia cartographic approach. The author of this paper, therefore, examines the current state of tourism industry and tourism mapping in Nigeria. Some of the hiccups to tourism mapping in the country are identified. The implications of the present poor state of tourism mapping on tourism planning, development, promotion and management in the country are briefly considered. The author makes a strong case for the adoption of a multimedia cartographic approach to tourism mapping in Nigeria. A case of mapping wildlife parks in Nigeria is presented to demonstrate the prospects of effective multimedia tourism mapping of the country. Furthermore, the author identifies and discusses various existing resources in the country that could be harnessed for efficient and sustainable production, distribution and use of multimedia tourist maps/atlases, using Geographical Information Technologies (GIT). Some potential challenges to effective GIT-based tourism mapping in the country as well as how such challenges could be overcome, are equally discussed. Similarly, a model for Web-based, multimedia tourism mapping using GIT is presented. With clear vision, the right policy instrument, mandate, legislation, funding and coordination in place, the current challenges to effective and sustainable tourism mapping in Nigeria can easily be surmounted.
