Authors: Pawlewicz Adam , Brodzinska Katarzyna , Zvirbule Andra , Popluga Dina 
Published: August 2020

Abstract
The development of organic farming is determined by many factors. On the one hand, it is an increase in demand for food produced in this production system, on the other it is a subsidy system for organic farming under the CAP. The purpose of the article is a comparative analysis of the direction of changes in the development of organic farming in Poland and Latvia compared to the EU in the years 2000-2017. Information was analysed on the organic farming i.e. the area of organic crops, the number of certified farms and organic retail sales, based on FIBL data from the years 2000–2017. An analysis of the trend of changes in organic farming in Poland and Latvia indicates that the development of organic farming in both countries has clearly accelerated after their accession to the EU and after covering organic farming by the CAP support system. However, the case of Poland is definitely different from the trend of changes in organic farming in Latvia and in the EU, where both the number of organic farms and their area increased, with the simultaneous development of the organic food market. There are many indications that mistakes were made in the organic farming subsidy system.

Abstract
In sub-Saharan Africa intensifying small-scale farming is essential in addressing poverty related issues in rural communities and the degradation of natural resources. Integrated Soil Fertility Management (ISFM) are the best practices used to improve the productivity of crops whilst maximizing agronomic efficiency of inputs applied and hence contributing to sustainable intensification. ISFM usually include the appropriate use of inorganic fertilizer and organic resources, good agronomic practices and appropriate use of germplasm. The survey was carried-out on the awareness of Integrated Soil Fertility Management practices in the Savelugu Municipal of Northern Ghana to study the awareness of integrated soil fertility management practices amongst farmers through the administration of questionnaires. A multistage method of sampling was used in selecting thirty (30) respondents randomly from five (5) selected communities namely Jana, Yapalsi, Diari, Nabogu and Gushie to make up a total sample size of 150 respondents. Frequency distribution and percentages were used to represent the data. Correlation analysis was used to test for the relationship between awareness, educational level and household size. The survey showed that majority of the respondents at ages between 21 and 30 years were married and majority with household size of 3 to 5 as well as primary and secondary education. Farming activities were carried-out by hand (80%). Majority of the respondents (43.3%) were informed about ISFM through demonstrations and 20% of the farmers apply inorganic fertilizer. About 85.5% of the respondents were aware of ISFM. The research also revealed that ISFM improves production and supports finances of respondents. The assessment of respondents’ perception of ISFM revealed a positive agreement of the effect of ISFM on soil health as well as improved production. In conclusion, it is thus suggested that it is needful for the involvement of the government on the adoption of ISFM via Non-Governmental Organisations (NGOs) locally and or internationally for a suitable advancement and to guarantee a sustainable environment with a world-wide corporation for improvement.
The Effect of separated Expansion Chamber Parameters on Exhaust Pressure Oscillations in Single Cylinder Motorcycle Engine
Authors: Banis Kārlis 
Published: August 2020

Abstract
This paper investigates the effect of separated exhaust expansion chamber parameters on pressure oscillations in spark-ignited internal combustion (IC) gasoline engines. It is known that exhaust expansion chambers are becoming increasingly more popular among both – original equipment (OE) and aftermarket equipment (AE) exhaust system manufacturers for performance-oriented motorcycles equipped with mainly single cylinder engines, but the companies are reluctant to reveal any detailed principles of operation of the mentioned expansion chambers. The subject of this research is the type of expansion chamber (separate) as used on performance-oriented motorcycles, particularly its’ effect on exhaust pressure pulsations as different chamber volumes, locations and passage sizes are tested. Time-dependent computational fluid dynamics (CFD) analysis was carried out in Solidworks Flow Simulation environment on a simplified exhaust header pipe model imitating engine operation at full load and steady speed. Honda CRF450R motorcycle engine was used as the example and fully defined using a 1D engine performance calculator software to determine the combustion chamber pressure and exhaust valve lift at any given crankshaft position. Volume flow rate of exhaust gasses at the header pipe inlet was calculated based on engine parameters and operating speed. The average pressure values with respect to physical time were measured and graphed across the header pipe inlet cross-section. Eight different header pipe and exhaust expansion chamber combinations were modelled, tested, and results compared at low, medium and high engine speeds. It was found that the presence of exhaust expansion chamber tends to dampen the amplitude and decrease the frequency of pressure oscillations generated at the opening of the exhaust valve(s). Observations show that the addition of an expansion chamber as per design of performance-oriented motorcycles helps to decrease the negative effect of engine tuning while also dampening the positive effect.

Published: August 2020

Abstract
One of the mechanisms for enhancing innovative processes in the industry is the application of the concept of the “four-link spiral”. In contrast to the 3-link spiral, this model as one of the most important components includes a “society”, acting as one of the actors of innovative transformations. Firstly, it is society that is the main consumer of innovative products being created and, thereby, establishes “requirements”, forming demands for the quality and parameters of future products; secondly, society, in turn, acts as the initiator and generator of innovations, forming the so-called “social capital” necessary for the implementation of directly innovative transformations. In this scientific work, the problems of the formation of a “smart specialization” strategy for the innovative development of the industrial sector of the national economic system based on the application of the four-link spiral concept are investigated. A system of quantitative indicators for assessing the innovative level of industrial development is presented. The experience of introducing the concept of a four-link spiral as a mechanism of innovative development of industry (on the example of the Republic of Belarus and the Russian Federation) is given. The aim of the article is to describe innovation processes in the Russian Federation and the Republic of Belarus and to develop an innovation transfer model.

El siguiente análisis pretende mostrar el panorama actual a nivel mundial relacionado con la presencia del Covid-19 en aguas residuales y potables. Muestra información recopilada de organismos oficiales o adaptados de estudios de investigación que se están llevando a cabo actualmente.
Al inicio de la pandemia, en Europa un grupo de científicos holandeses del Instituto de Investigación del Agua KWR encontraron rastro del coronavirus en las aguas residuales de una ciudad de Países Bajos antes de que se informaran de los casos de Covid-19. A partir de este momento se ha iniciado una carrera por parte de muchos centros de investigación y empresas del ciclo integral del agua, orientada a demostrar que el virus no está activo en las aguas residuales y potables. Desde el KWR, los científicos aseguran que “el agua potable está muy bien protegida contra todos los virus, incluido el nuevo coronavirus”. Es importante resaltar que el agua no está listada como una de las vías de transmisión del virus que recoge la Organización Mundial de la Salud (OMS).

Authors: Andromeda Vega F. , Putra I Made Wahyu S. 
Published: August 2020

Abstract There is still a delay time of up to 86% and utilization of the pier that has not been optimal causing inefficiency in ports in Indonesia. Idle time that occurs at the port is due to the slow processing of ships and goods documents. The implementation of the Inaportnet system is expected to accelerate clearance completion in an effort to expedite the Estimated Time of Departure. This research was conducted at PT Dharma Lautan Utama Tanjung Perak Surabaya Branch using a descriptive qualitative research method. The results showed that the process of completing ship clearance at PT Dharma Lautan Utama Surabaya Branch has changed using the online system or using the Inaportnet system, but this system is still constrained by inadequate internet connections. The number of vessel documents that must be completed, the checking system for expired date of ship certificates is still manual, the ups and downs, and the length of time waiting for the cargo to arrive at the port also causes the length of the clearance process at Tanjung Perak Port. Keywords: delay time; clearance; Inaportnet system; Estimated Time of Departure; ship. Abstrak Masih adanya delay time hingga 86% serta belum optimalnya utilisasi dermaga yang belum optimal menyebab-kan ketidakefisienan pelabuhan di Indonesia. Idle time yang terjadi di pelabuhan disebabkan karena waktu pengurusan dokumen kapal dan barang yang masih lambat. Penerapan sistem Inaportnet diharapkan dapat mempercepat penyelesaian clearance dalam upaya memperlancar Estimated Time of Departure. Penelitian ini dilaksanakan pada PT Dharma Lautan Utama Cabang Tanjung Perak Surabaya menggunakan metode penelitian deskriptif kualitatif. Hasil penelitian menunjukkan bahwa proses penyelesaian clearance kapal pada PT Dharma Lautan Utama Cabang Surabaya telah berubah menggunakan sistem online atau menggunakan sistem Inaportnet, tetapi sistem ini masih terkendala oleh koneksi internet yang kurang memadai. Banyaknya dokumen kapal yang harus diselesaikan, sistem pengecekan expired date sertifikat kapal masih manual, terjadinya pasang surut, dan lamanya menunggu muatan tiba pelabuhan juga menyebabkan lamanya proses clearance di Pelabuhan Tanjung Perak.
