This research aims to exploit total polyphenol, flavonoid contents, antioxidant and allelopathic activities of leaf extracts, and essential oil compositions from leaves of Acronychia pedunculata (L.) Miq. The results indicated that the leaf extract from ethanol 100% (E100) possessed a lower total polyphenol and flavonoid content than the extract from ethanol 70% (E70). In contrast, the antioxidant activity from E100 extract with IC50=612.9±12.9 μg/ml was stronger than that of E70 extract with IC50=1225.5±6.9 μg/ml. Regarding allelopathic activity, while the extracts from E100 and E70 inhibited root growth of radish, both extracts promoted root growth of lettuce. Especially, E100 extract with 3 mg/ml inhibited root growth of radish up to 48.1%. Moreover, using water solvents, the extracts reduced root growth of both the radish and lettuce. By GC-MS analyses, 33 compounds were identified from A. pedunculata essential oil. The major constituents were caryophyllene (47.09%), humulene (17.28%), α-copaene (4.98%), isoledene (3.59%), and (-)-α-panasinsen (3.51%), other compounds were accounted for lower 3%.

The area of Petapan Hamlet is an upstream area where there are still many water sources as the main flow for downstream irrigation. There is one secondary stream with a fairly large channel size (2 m wide and 1 m deep). The flow velocity of this channel averages 1.6 m / sec with an average water depth in the dry season of 40 cm. The relatively large size of the channel results in a water flow of 1.26 liters / second. There is one place where the dimension of the channel shrinks for the distribution of irrigation to a width of 1 meter so that the correlation with a steady flow rate will increase. The people of Petapan Hamlet have built a tourism area based on green tourism with educational tourism as the main point. This tourism area is traversed by the subak water channel which will later be used as a place to play and educational tours about the subak irrigation system for tourists visiting this place. There is no supporting infrastructure in developing this tourism, both facilities and supporting facilities for the convenience of tourists in carrying out their activities The energy source that will be used to support the development of educational tourism is obtained from PLN sources.

The flexibility in accounting standards and principles, lead to incentives for managers to show a good picture of the companies. It is logical and rational for managers to attempt to smooth income by using certain accounting devices to reduce the companies’ income fluctuation over time to improve relations with creditors, investors, and employees. Income smoothing enables companies to stabilize earnings and thereby increase earnings predictability. For detecting income smoothing through examining the financial statements Eckel’s (1981) approach (income variability approach) has been the most popular and most used one. In this research study, we use a selection criterion between smoothers and non-smoothers hotel companies based on the income smoothing. This study aims to classify Serbian hotel companies during the period 2016-2019 as smoothing and non-smoothing hotel companies. The method used to determine the presence or absence of income smoothing and the company value results is based on the coefficient of variation model proposed by Eckel (1981). According to the coefficient of variation method, the more the income smoothing (IS) index tends to zero, the more smoothed out the company’s earnings are. This study examines the presence of artificial income smoothing in 22 Serbian hotel companies. A binomial test is used to test the hypothesis. As a result of research, there are no significant statistical indicators of income smoothing practices in Serbian hotel companies during the period 2016-2019.

Unlike the passive learning, in active learning students are more engaged in the evaluation process of presentation made by their peers, which significantly encourages student participation. Applying Classroom Response System students gain the ability to instantly respond and react, since this activity requires continuous attention. Promoting student-instructor interaction this technique leads to the involvement of students to class discussion simultaneously providing information about efficacy of the comprehension of the new topic. A significant point to be taken into consideration is the individual approach to every student.

The results of a project on news segmentation at Radio Nacional de España (RNE) carried out by the RTVE Technological Innovation and Media Management areas is presented. The aim of this project is to apply artificial intelligence to automatically transcribe and cut the news items that make up a radio news program. The main goals of this project are to increase the accessibility of the content and to allow its reusability on various platforms and social media. The project was planned in two phases, covering system configuration and service delivery. The minimum quality criteria required were defined in advance, both for automatic voice transcription and for news segmentation. For the speech-to-text process, the highest word error rate (WER) allowed was 10%, while the precision rate for the news segmentation was 85%. System performance in both transcription and segmentation was considered to be sufficient, although a higher degree of accuracy in news cutting is expected in the coming months. The results show that, despite using these quite mature technologies, adjustment and learning processes and human intervention are still necessary.

Resumen
Se presentan los resultados del proyecto para la segmentación en noticias de los informativos de Radio Nacional de España (RNE) llevado a cabo por el Área de Innovación Tecnológica de Radio Televisión Española (RTVE) en colaboración con la Dirección de Medios de RNE. El objetivo de este proyecto es aplicar la inteligencia artificial para el cortado automático de las noticias que componen un informativo radiofónico, para su posterior difusión en la web de RTVE y en medios de comunicación social. El proyecto se planificó en dos fases: una primera de configuración y ajuste del sistema, y una segunda de prestación del servicio propiamente dicho. Los criterios de calidad mínimos exigibles se definieron previamente, tanto para la transcripción automática del habla a texto, para la que se estableció una tasa de error por palabra máxima (WER) del 10%, como para la segmentación de noticias, para la que se definió una tasa de precisión superior al 85%. El rendimiento del sistema tanto en la transcripción como en la segmentación se considera suficiente, si bien se espera alcanzar un mayor grado de precisión en el cortado de noticias en los próximos meses. Los resultados ponen de manifiesto que, a pesar de ser tecnologías bastante maduras, son necesarios procesos de ajuste y aprendizaje con la intervención humana.

This article discloses the requirements for the installation of poultry houses and indoor equipment for keeping guinea fowl. In the construction of poultry houses it is necessary to take into account the behavioral and physiological characteristics of guinea fowl on which their growth and development, productivity, feed consumption and disease resistance. For construction of a poultry house choose the elevated site or with a small slope that thaws and rain waters did not collect and did not stagnate. The size of the poultry house depends on the number of livestock in it, so it is recommended to place up to 5 heads per 1 m2 of floor area. The roof of the poultry house is made sloping. Litter is used in the premises for keeping guinea fowl: peat, straw, sawdust, litter thickness –10-15 cm. During the whole winter period the litter is not removed, only fresh is added regularly. If the litter is heavily soiled, the contaminated part is removed and a clean one is added. For winter keeping of guinea fowl the room is well warmed, without allowing in it humidity and formation of a mold. When keeping guinea fowl in the summer, it is recommended to equip them with a walking yard, fenced with wire mesh, around which bushes and trees are planted or canopies are made to protect the bird from direct sunlight. In winter, an artificial heat source is installed in the poultry house, for example, electric brooders, electric lamps with a metal shade-reflector located at a height of 15-20 cm from the floor. Seats for guinea fowl are made of chipped bars with rounded upper edges, which are installed on the opposite side of the windows in a horizontal form. Nests are set in the henhouse long before the laying hens begin to lay eggs, so that the guinea fowl have time to get used to them and lay eggs in the nests. Feeders are made like troughs, which prevents contamination and scattering of food. A turntable is mounted on the brackets on top of the feeder, it rotates around its axis and also prevents the feed from scattering. At the height of the feeder is made so that the edges of the sides were at the level of the back of the bird. It is better to use vacuum or nipple drinkers to water the guinea fowl, which provide them with fresh running water.

Authors: Syed Areeja
Published: June 2021

In international relations, an act of demonstrating cooperation and goodwill with an adversary is known as the Confidence-Building measure. The motive behind these measures is to alleviate misapprehension, tension, fear, and angst between two or multiple parties by emphasizing trust and restricting acceleration in a conflict. India and Pakistan share a prolonged history of mistrust and animosity. The repercussions of this acrimonious relations are profound and extensive. In the past, numerous measures have been initiated by both states to stabilize peace and rekindle the mutual working relationships. To accomplish the challenging task, numerous non-military CBMs have also been initiated from both sides intermittently. However, none of them delivered the desired outcomes and successfully triggered confidence as anticipated. Therefore, in this article, the author delves into finding out the fundamental reasons for the failure of these CBMs between India and Pakistan held in 2001 – 2019.

Pakistan and India have failed to establish substantial and sustained economic relations between them. Despite being neighbours, they couldn't enjoy a good volume of bilateral trade in multiple sectors. This study traces the history of bilateral trade between Pakistan and India. While identifying patterns of trade between them, the study attempts to identify barriers in bilateral trade between them like trade regimes, non-tariff barriers and other discriminatory measures. The study also makes an attempt to address the question concerning how the impediments in bilateral trade can be removed to enhance bilateral trade and economic connections. On the basis of interviews of Key Informants (KIs), this study explores the potential of bilateral trade between Pakistan and India and finds possible sectors where bilateral trade can be augmented. Lastly, this study finds possible sectors where Pakistan and India can initiate joint ventures to seek win-win approach in bilateral economic relations.
