Abstract

The population of spider feeding on insect pests of cotton was observed throughout the growth period of the crop, being maximum in the month of July. Chrysoperla was observed from second fortnight of June to harvesting of the crop being maximum in November. The incidence of coccinellids was recorded from the middle of August to middle of September and remained till harvesting of the crop being maximum in the first fortnight of November. A positive significant effect of maximum and minimum temperature on spider and negative significant effect on population of chrysoperla and coccinellids was recorded. Evening RH exerted positive significant effect on spider and negative significant effect on coccinellids.

Abstract

Various theories have been put forward on the demographic and health effects and consequences of socioeconomic development. In this study, we used the theoretical findings of the epidemiologic transition as a starting point to examine the 2020 values of the three main cancer indicators (incidence, mortality, prevalence). These values were compared with socioeconomic development variables for 170 countries. The countries were grouped using hierarchical clustering, and linear discriminant analysis was used to evaluate how appropriate the clustering was. Principal component analysis was used to examine, by group, which parameters are significant in each principal component and what background factors underlie the data. The results seem to confirm the association between cancer and socioeconomic background.

Abstract

The rapid surge of global oil prices, on account of the pent-up demand after COVID-19 and the Russian-Ukraine war, has significantly contributed to the cost-push inflation as well as twin deficits, predominantly in developing economies. Motivated by the intention to curb the inflation, governments of several oil-dependent economies have rolled out fiscal measures to provide immediate relief to households through subsidizing the fuel component of the consumption basket. This paper provides a case study of Pakistan, wherein the effectiveness of untargeted gasoline and diesel subsidies has been gauged against alternative direct disbursement mechanisms. The analysis reveals that under the price-control based indirect subsidy disbursement mechanism, only 11% of the total domestic subsidies were directed to the poorest 40% of the households, whereas approximately 55% of the total subsidies were allocated to the 20% of the most liquid household segment. The case study analyzes the performance of alternative direct subsidy disbursement mechanisms which transpires into the potential fiscal savings of PKR 74.63 billion, while providing coverage to 40% of the lowest household segment. The study also evaluates the implication of the pass-through of the true prices on the national consumption of gasoline and diesel in the short-term, which reveals the sharp reduction of petroleum consumption in the total bill from 37% to 23%, thereby providing substantial relief to the current account balance. The finding provides key insights for economies to institutionalize the necessary social protection system and progressively transit to the direct subsidy disbursement mechanism while striving to contain the cost-push-based inflation triggered through the rapid movement of global oil prices.

Abstract

The theoretical estimation of sound absorption coefficient of a surface may give very different results. This will depend on the type of sound field assumed in the theoretical model used for the estimation of its sound absorption coefficient. Absorption coefficients for normal and diffuse sound fields are widely known, although they may be far from the absorption values given by an absorbing material when it is finally installed inside a room or enclosed space, where a sound field closer to a spherical wavefront is more likely to be found. This work presents a theoretical study, which is addressed at obtaining a mathematical expression to calculate the sound absorption coefficient for a variable range of incidence angles, called αs. The presented method uses a circular sound field incidence as an approximation to a spherical incidence. The estimation of this coefficient αs is based on obtaining the incident and reflected sound fields for a surface located facing a lineal source. The advantage of this calculation method over others lies on its capability to give results for circular, normal and random wave incidence depending on the range of incidence angles considered in the calculation.

Abstract

At the end of August 2012 the Polish Parliament enacted the Act on State Marine Accident Investigation Commission, which regulates its organization and operation. The Act transposed, within its regulation, Directive 2009/18/EC of the European Parliament and of the Council of 23 April 2009 establishing the fundamental principles governing the investigation of accidents in the maritime transport sector and is based on the Code of the International Standards and Recommended Practices for a Safety Investigation into a Marine Casualty or Marine Incident (Casualty Investigation Code), issued by the International Maritime Organization (IMO) together with amendments to the SOLAS Convention. The purpose of the Directive, as well as the Casualty Investigation Code, is to improve maritime safety and the prevention of pollution by ships by facilitating the expeditious holding of safety investigations and proper analysis of marine casualties and incidents in order to determine their causes. The EU Parliament obliged, through the Directive, the EU Member States to ensure that the safety investigations are conducted under the responsibility of an impartial permanent investigative body, endowed with the necessary powers, and by suitably qualified investigators, competent in matters relating to marine casualties and incidents. This impartial permanent investigative body had been named in Poland: Państwowa Komisja Badania Wypadków Morskich [the State Marine accident Investigation Commission] and began its operation in May 2013 upon the appointment, by the Minister of Transport, Construction and Maritime Economy, of the third one of five statutory members of the Commission. Since the beginning of its activity the Commission has initiated 77 safety investigations, prepared and adopted 272 resolutions, published 53 safety reports and issued more than 30 safety recommendations. The establishment and activity of the Commission leads to greater awareness of casualty causation and has a positive impact on the level of maritime safety.

Abstract

This paper presents an approximate analytical model for estimating the transmission loss (TL) of a finite rectangular plate in the low frequency range, which is based on the modal summation approach (MSA) taking into account the modal radiation impedance and fluid loading. The mode-dependent radiation resistance is calculated using the Rayleigh integral. The fluid loading is taken into account through the natural frequency modified by the added mass. The results are compared with the ones of Statistical Energy Analysis (SEA) coupled with FEM and FEM coupled with BEM. In addition, the effects of the various vibration modes and the fluid loading on TL, and a way for reducing the calculation time are discussed.

Abstract

The objective of the present study was to identify the dynamics of Alternaria blight spread on spring oilseed rape lower, middle and upper leaves and siliques, to determine the disease incidence (DI) and severity (DS) on leaves, stems, siliques and seeds under the effect of prochloraz and tebuconazole. Efficiency of the fungicides was compared in relation to their application time. Field experiments with the spring oilseed rape cv. 'Star' were conducted at the Lithuanian Institute of Agriculture during 1997-1999.

Abstract

This article surveys the relations between the Polish Radio and the German Broadcasting Corporation (Reichs-Rundfunk-Gesellschaft) in the interwar period. In its early phase the relationship was overshadowed by disputes over programmes on Upper Silesia and the takeover by a German company of the radio station in the Free City of Gdańsk (Danzig). After Hitler became chancellor in 1933 there was a marked improve- ment in relations: the two parties even made an agreement to relay each other's programmes. However, in September 1939 the German radio network (RRG) actively aided the German army in its invasion of Poland.
