The objective of this work was to examine the effect of various loads on donkeys' physiological and behavioural responses to evaluate welfare. Donkeys weighing of 132-172 kg (159 ± 11 kg) and totally 20 were used for the experiment. The experimental design included two wheeled cart × seven load class (an increment of 100 kg) with five repetitions each, and the travelled distance was 2 km. Travelled time, behavioural occurrences and physiological responses were recorded. Statistical analysis was conducted using SAS (version 9.4) software programme. When loads were 500-700 kg, heavy and rapid panting and falling down occurred frequently. When loads increased successively and reached 500, 600 and 700 kg, speed started declining from 3.68 km/hto 3.5, 2.94 and 2.54 krn/h, respectively, indicating that speed and applied loads are inversely correlated (P 〈 0.001). Heart rate was 129 ± 11 bpm at 700 kg, and in respect to resting state, donkeys' heart rate elevated by a factor of up to 3. As the load exceeded 400 kg, the speed declined significantly, and behavioural occurrences like heavy panting and falling down confirmed this. This leads to the conclusion that donkeys could pull about 2.7 times of their live weight. But if they have continuous and long working hours (about 6 h), it is recommended to keep load of two wheeled cart about double of donkeys live weight so as to safe guard donkeys' welfare.展开更多

The SEP and developed alternative single extrac- tion methods were validated by the analysis of certified reference material BCR 601. By the use of optimized sonication and microwave conditions, steps 1, 2 and 3 of the BCR sequential extraction methods (excluding the hydrogen peroxide digestion in step 3, which was not performed with sonication and microwave) could be completed in 15-30 min and 60- 150 s, respectively. The recoveries of total extractable metal contents in BCR 601, obtained by three single extractions ranged from 93.3%-102%, 88.9%-104% and 81.2%-96.2% for CSE, USE and MSE, respectively. The precision of the single extraction methods was found in the range of 3.7%-9.4% for all metals (n = 6).展开更多

Principally, these transactions consist of applications for birth certificates, tax payments, payments of fines, however, very rarely, or never can someone incorporate a business by means of e-government services. Rare also, are cases in which the consequences of business incorporation can be evaluated through the internet--for example employment creation or the attraction of investments. With respect to business incorporation the internet portal of the government of the state of Puebla is of no help, since it must be done in person in every case.展开更多

Schott) is an important underutilised crop in South Africa, East Africa and Indonesia. Three taro landraces, namely, Dumbe Lomfula (wild), KwaNgwanase and Umbumbulu, were collected from two locations in KwaZulu-Natal (KZN), South Africa, and planted at two locations, Pietermaritzburg (KZN) and Roodeplaat, Pretoria. Ago-morphological characterisation of vegetative and corm characteristics were done four months after planting and at harvest, respectively. Sampling for DNA fingerprinting using five SSR primers was done using leaf material four months after planting. Agro-morphological characterisation was useful in showing differences between the wild landrace and the two cultivated landraces, as well as identification of dasheen and eddoe types. SSR primer characterisation showed that despite significant morphological difference, the wild Dumbe Lomfula and Umbumbulu landraces were closely related but different from the KwaNgwanase landrace. Although landraces showed great morphological variation, this did not necessarily imply genetic variation. It is concluded that SSR primers are more useful for characterising taro landraces.展开更多

This complex, during its almost 100 years of operation, has undergone significant modifications and enhancements mainly due to technological changes driven by the replacement of steam traction by electric traction, and then by diesel-electric traction. Despite this, the complex maintained an impressive architectural consistency. Unfortunately, most of the buildings of this complex are unused and in disrepair, being the target of invasions, vandalism and theft of materials that if not stopped will cause irreparable damage to its structure and to the local ambience. The question that appears most urgent, therefore, is to seek ways to repossess this group of workshops in order to meet the current demands of urban development without losing the characteristics which form its architectural and urban identity in a city in accelerated mutation.展开更多
