A group of 12 farmers managing a total of 8845 ha in the West Waikato Region of the North Island, conducted a project to understand and overcome poor livestock performance during the summer- autumn period. Pastures and livestock were monitored to measure the impact of the conditions. Metabolisable energy (ME) of pasture averaged 9.0, 9.8 and 9.3 mega joules per kg of dry matter over the 3 years of study and elevated levels of pasture toxins were consistently found from mid- January to the end of May. To counter these conditions, farmers adopted varying strategies including pasture management and alternative feeding (silage and forage crops). A computerbased tool that enabled the user to make livestock feeding decisions based on the pasture cover, the ME of the pasture, and the quantity and ME of a feed supplement was developed. Farmers were able to reduce the proportion of damaged livers in lambs from 60 to 40% of the flock, which was against the district trend. When the right strategies were implemented, lamb and cattle liveweight gains increased from 52 to 146 g/day and 0.34 to 0.5 kg/day respectively. On average, ewe reproductive performance also improved during the period from 2.4 to 2.8% of lambs scanned/kg ewe body weight. The project emphasised to farmers that their resident pastures did not meet the needs of a high performing livestock production system and that alternative feeding strategies were required if higher performance was to be achieved.

There were signs of the first civilization known to humanity for more than 6000 years BC in the north of Iraq have disappeared this civilization to appear after 500 years in southern Iraq, the Sumerian civilization, which was considered as the opinion of scientists or civilizations, exceeds the impact to Asia and the countries that had been in contact (Sumerians) and see them today in other towns and villages. In subsequent periods of time appeared distinct personalities to their nature, religious, social, special clothing with clothes seem especially long. And usually dress is made from raw wool material making them in the Sumerian era. Put the garment on the body and leaves the top of the right shoulder with the survival of an open hand. There are of special clothing used by the clergy in the exercise of religious mourning rituals .There are traditional clothes to the clergy of other faiths. The clothing we see in the beginning of the third millennium BC has gained status in society in general, and was also the head cover. The animals have for centuries symbolized the signs of a divinity that we see hanging on the walls of some temples in northern Iraq. Centuries have been mentioned in the history of the Arabian were animal horns in Sumerian times to symbolize the moon in the Sumerian language .

Light-chestnut soils of the arid zone of the North of the Astrakhan region, even if all the standards of agricultural engineering are observed, are characterized by unfavorable agrochemical and water-physical properties for most crops. To successfully solve the problems associated with increasing adaptation of zonal agriculture to harsh climate conditions, it is necessary to search for new resource-saving technologies. The purpose of the work is to identify the impact of resource-saving methods of basic soil cultivation on the yield of spring barley in the semi-desert conditions of the North of the Astrakhan region. The organization of field experiments, observations and laboratory analyses were carried out according to the method of conducting field experiments Dospekhov B. A. and Guidelines for conducting field experiments with forage crops (research Institute of feed). The results of the conducted field experiments and laboratory studies give reason to speak about the feasibility of using a resource-saving soil-cultivating organ ROPA in the zone of unstable moisture in the North of the Astrakhan region. Loosening this unit contributes to an increase of 25% of the total spring stock of soil moisture. The introduction of this deep tillage (H=0.40-0.45 m) and tools for its implementation (ROPA) allows you to get in the rain-fed conditions of the arid zone of the North of the Astrakhan region from one hectare of arable land to 1.24 tons of barley Vakula and 1.30 tons of barley Ratnik.

During the summer of 1847 the impact of famine, disease, and social upheaval in Ireland was felt in port cities across the North Atlantic World. As an important hub of commerce and migration, Montreal was deeply affected by these events. The arrival of thousands of Irish migrants, many of whom had contracted typhus during their journey, touched off a contentious debate in the city. An engaged and alarmed public threw their support behind a proposal put forward by representatives of the municipal government that called for the construction of an elaborate quarantine facility just down the St. Lawrence River from the city. This facility, which migrants would be confined at until their healthy status was confirmed beyond reasonable doubt, promised to return order not only to Montreal, but to the entire migration process. The body appointed by the colonial administration, however, rejected the proposal, and tabled a far more modest plan that would continue to house migrants in sheds located just a stone’s throw away from the city’s western suburbs. The highly charged debate that ensued furnishes us with an opportunity to examine how the city’s political elite and the broader public were thinking through questions about migration, public health, and the contours of liberal governance. The objective of this article is to consider the role that moments of crisis such as this played in shaping the city’s political culture, and to place the events of 1847 in the context of the larger struggle between local and metropolitan authority occurring during this period.

Aim of study: To investigate the impact of adopting new feeding precision technology on pig production.Area of study: Four EU countries (Germany, France, Poland and Spain) during the period 2010–2015.Material and methods: The Färe-Primont index was used to estimate total factor productivity change and its components, technological change and efficiency change.Main results: German, French and Spanish farms experienced total factor productivity (TFP) progress, while Polish farms did not for both feeding strategies. Our empirical findings suggest a high impact on the productivity of ad libitum feeding technique compared to the restricted one for all countries.Research highlights: Precision feeding strategies provide another avenue to more sustainable livestock production and further evidence that implementing individual ad libitum feeding systems for pigs could enhance farm’s productivity.

Krian Bypass intersection is a very crowded route because of its location near Sidoarjo and Mojokerto Regencies for the economic distribution of Surabaya City. There needs to be phase regulation, road widening or fly over so that the intersection traffic volume is not getting saturated. As a benchmark is the forecasting of traffic performance carried out for 3 years from 2018 to 2021. Based on the results of forecasting, the Krian Bypass intersection will decrease its DS value by widening the road so that the green time cycle will be low and turn right impact the DS value below 1 (one). The lowest 2018 DS is 1.61, while the highest DS is 2.49. While the lowest year 2021 DS is 2.72, while the highest DS is 4.85. For the solution with the right turn phase for each intersection to the north DS = 1.02, U-RT = 0.82, S = 1.38, S-RT = 0.69, T = 1.24, T-RT = 0.78, B = 1.79, B-RT = 0.04 . The solution for forecasting the flow of Krian Bypass in 2021. The calculation results made with effective width engineering, turn right and green time can reduce the DS value (Degree of Saturation) still shows DS value> 0.75 - 1, then fly over is constructed with a scenario of 20% vehicles through existing and 80% of vehicles through fly over. Year 2021 The impact of fly over shows North DS = 0.4, South = 0.51, East = 0.56, and West = 0.45

New Zealand dairy farmers rely on pasture grazed in situ to feed their herds. Summer is the most difficult period to manage because pasture production is usually highly variable and, in most years, less than herd requirements. Dairy farmers can use a range of options (e.g., summer forage crops, silage) to minimise the impact of both variable and inadequate summer feed supply. Much has been written about recommended procedures for planning and monitoring pasture-based systems, but there is little documentation on the processes actually used by New Zealand dairy farmers. To this end the summer management processes of three high-performing Manawatu seasonal supply dairy farmers were studied over 4 years. The farmers used management systems based on their experience. A range of simple techniques was used to identify potential feed deficits. The farmers then used a set of decision rules to select the best option or combination of options to overcome feed deficits. The study highlighted the potential benefits that could accrue from integrating farmer knowledge with scientific knowledge. Keywords: dairy farmers, decision-making, farmer knowledge, monitoring, summer management

ABSTRACTCross-University Master Degree in Human RightsCross-Culture and DevelopmentUniversidad Pablo de OlavideUniversidad Internacional de AndalucíaAuthor: CRISTINA ALONSO SAAVEDRCounselor: YAYO HERRERO LÓPEZAbstract: in the current investigation work, we will analyse the right to the energy supply, as a leading good to other improvements in decent housing, education, health, etc. We will also observe how is the impact of the supply in the different aspects of daily life in the communities and specially in their women. The case study will be developed into the frame of the international development cooperation, taking several projects of rural electrification in the South coordinated by develompent NGOs from the North. The analysis will make a panoramic and historical revision of the evolution of the international develompent cooperation and the different approaches from a gender perspective. Later on we will deepen the concept of Energy and the evolution of its consumption along the Human History, being specially aware of not skipping the fact that the use of women bodies as an energy resource is essential to mantain the current economical system. We are in the need of a different paradigma that questions the basis of Capitalism and Patriarchy, because here is where the hegemonic concepts are hold. Thus, we will propose an analysis framework with an Ecofeminist approach to obtain sustainability and we will use it to analyse the projects of rural electrification.The critical Human Rights theory defines the rights as fighting processes that pursue an egalitarian access to material and immaterial goods. Taking this into account, the energy supply is understood as a material good that will lead to the obtention of other material and immaterial goods. Thus, the technology implemented in the communities for the energy supply will go together with a fighting process to get an egalitarian access, along with processes of social transformation. So, the technology installed must mean a real emancipation tool for the community and especially for women. This emancipation will depend on the process rather than on the transference as a simple technological aim. This is why the development NGOs that work for the defense of the rights in this communities suppling them energy must go beyond a simpe technified approach. That means the need of focusing in the process, letting the community participate and reviewing the models of participation from a gender perspective. The goal must then be the satisfaction of the basic needs of the population and especially the real needs of women, because they have been hidden under gender roles. Besides, the implementation of technology cannot forget aspects as environmental, social and gender justice for the effective and real achievement of the desired sustainability.

SummaryRecently, there has been a proliferation of international agreements imposing minimum standards on states in respect of their treatment of foreign investors and allowing investors to initiate dispute settlement proceedings where a state violates these standards. Of greatest significance to Canada is Chapter 11 of the North American Free Trade Agreement, which provides both standards for state behaviour and the right to initiate binding arbitration. Since 1996, four cases have been brought under Chapter 11. This note describes the Chapter 11 process and suggests some of the issues that may arise as it is increasingly resorted to by investors.

Abstract. In the study, the neural basis of emotional reactivity was investigated. Reactivity was operationalized as the impact of emotional pictures on the self-reported ongoing affective state. It was used to divide the subjects into high- and low-responders groups. Independent sources of brain activity were identified, localized with the DIPFIT method, and clustered across subjects to analyse the visual evoked potentials to affective pictures. Four of the identified clusters revealed effects of reactivity. The earliest two started about 120 ms from the stimulus onset and were located in the occipital lobe and the right temporoparietal junction. Another two with a latency of 200 ms were found in the orbitofrontal and the right dorsolateral cortices. Additionally, differences in pre-stimulus alpha level over the visual cortex were observed between the groups. The attentional modulation of perceptual processes is proposed as an early source of emotional reactivity, which forms an automatic mechanism of affective control. The role of top-down processes in affective appraisal and, finally, the experience of ongoing emotional states is also discussed.
