This study investigated the effects of parity, prior experience, and environmental conditions on the incidence of savaging on seven commercial farms. Results indicated that 3.40% of gilts and 1.22% of sows killed one or more piglets (P < 0.05). Fourteen percent of sows that savaged as gilts also savaged during their second farrowing, compared to 0.8% of sows that had not reviously savaged. The incidence of savaging was similar among gilts during the first (all gilt herd) and second (gilt/sow herd) farrowing cycles. Key words: Savaging, gilts, sows, pigs, maternal behaviour

Regional characteristics and diversity of Podiliya environmental conditions are considered, and there is shown that they were favorable to the settlement processes and performed multiple functions at all stages of history, one of which is the ability to use environmental conditions diversity as a source of physical and spiritual recovery. Special attention is given to the Podiliya landscapes formation, as one of the attraction factors. Key words: environmental conditions, landscape, tourism, recreation, region, forest-steppe.

System Approaches

As part of the airworthiness requirements, an aircraft cannot be dispatched with an inoperative equipment or system unless this is allowed by the Minimum Equipment List (MEL) under any applicable conditions. Commonly, the MEL mirrors the Master MEL (MMEL), which is developed by the manufacturer and approved by the regulator. However, the increasing complexity of aircraft systems and the diversity of operational requirements, environmental conditions, fleet configuration, etc. necessitates a tailored approach to developing the MEL. While it is the responsibility of every aircraft operator to ensure the airworthiness of their aircraft, regulators are also required to publish guidelines to help operators develop their MELs. Currently, there is no approved standard to develop a MEL, and this poses a challenge to both aviation regulators and aircraft operators. This paper reviews current MEL literature, standards and processes as well as MEL related accidents/incidents to offer an overview of the present state of the MEL development and use and reinstate the need for a systematic approach. Furthermore, this paper exposes the paucity of MEL related literature and the ambiguity in MEL regulations. In addition, it was found that inadequate training and guidance on the development and use of MEL as well as lack of prior experience in airworthiness topics can lead to mismanagement and misapplication of the MEL. Considering the challenges outlined above, this study proposes the combination of system engineering and socio-technical system approaches for the development of a MEL.

Three spring and two fall crops of greenhouse tomato (Lycopersicon esculentum L. Mill; various cultivars) grown in "Harrow" peat bags were irrigated 1, 4, 8 or 16 times daily. All plants received the same volume of fertilizer solution which varied with time from 0.2 to 1.0 L plant−1 d−1 according to crop and environmental conditions. The results showed little or no effect of irrigation frequency on early or total yield, number of grade no. 1 fruit, or fruit size. Key words: Lycopersicon esculentum, marketable yield

The aim of the research was to check whether there is a relationship between the perception of the workplace by the employee as attractive and the level of job satisfaction experienced by him/her. These analyzes are part of the search for environmental conditions of job satisfaction. The study group consisted of 100 office employees were asked to complete three questionnaires: Job Description Questionnaire by Neuberger and Allerbeck, Job Affect Scale by Brief, Burke, George, Robinson and Webster, and authors’ tool to measure the physical assessment of attractiveness the workplace. The results obtained confirm that the attractiveness of the workplace together with the perception of individual elements of space arrangement are related to job satisfaction, both in the emotional and cognitive dimensions. Thus, the results can be a premise to be used by the employer in the process of building an employer branding as inside-out as well as outside-in. Key words: workplace attractiveness, job satisfaction

The article analyzes the agro-ecological situation and problems of soil use in Lviv region. It is established that the conduct of agriculture is often not the landscape and environmental conditions of the area and agro-ecological conditions of cultivation of agricultural crops. In soils have become widespread degradation processes, such as water and wind erosion, acidification, dehumidification, the depletion of elements of the other power plants. The measures of rational use and protection of soils are proposed. Key words: Lviv region, soil, agro-ecological state of, degradation, soil protection.

We propose that the optimum habitat of the percid fishes Perca flavescens, P. fluviatilis, Stizostedton vitreum vitreum, and S. lucioperca in lakes may be defined by the littoral and sublittoral environmental conditions equivalent to those in large, temperate rivers. Analogous habitat conditions include sand or gravel substrate, low current velocity, reduced light penetration (Stizostedion spp. only), temperatures optimal for growth and reproduction, and well-oxygenated spawning substrates. The species' evolutionary origins and reproductive patterns also reflect their riverine ancestral habitat. Evidence in support of the hypothesis is derived from the diversity of papers contributed to the PERCIS Symposium. Key words: Percidae, habitat, theory, Perca, Stizostedion

The importance of microrelief in relation to mass loss was studied in a Minnesota ombrotrophic forested peatland. Litter and paper strips placed in hummocks for 1 yr lost significantly more mass (two and three times, respectively) than similar material placed in hollows. Less favorable environmental conditions for decomposition, especially lower temperature, reduced decomposition in the hollows. Key words: Peatlands, ombrotrophic, decomposition, Histosols

And Control

Physiological and behavioural responses of 17 bull and 12 heifer dairy calves (80.9 ± 1.4 kg) to either hot-iron dehorning or dehorning followed by scalpel castration were compared to both control and sham procedures and to each other. Blood samples were collected via jugular catheters at 15 and 30 min, 1, 2, 4, 24, and 48 h post procedure, sham or control. Cortisol levels remained elevated above controls for at least 2 h after castration and 30 min after dehorning. Initial (T0–T15 min) cortisol responses to castration were not different from those to dehorning. However, they were greater than for dehorning at 2 and 4 h post procedure. Both castrated and dehorned calves kicked and vocalized more frequently (P < 0.05) than during sham procedures. Struggling was greater during dehorning than the sham, but occurred less (P < 0.05) during castration than the sham possibly due to the prior experience of dehorning. Dehorned calves had a higher (P < 0.05) occurrence of both struggling and kicking compared to castrated calves. Heart rate was higher (P < 0.001), compared to control values, in both the sham (P < 0.02) and dehorned calves. Non-anaesthetized dairy calves had elevated cortisol, and heart rate levels as well as more severe behavioural responses to castration and dehorning compared to sham and control treatments. Differences in the responses to each procedure may have been due to handling differences or prior experience of dehorning. Key words: Behaviour, castration, cortisol, dairy calves, dehorning, heart rate
