AbstractSmall domestic cooking furnaces are widely used in China. These cooking furnaces release SO2 gas and dust into the atmosphere and cause serious air pollution. Experiments were conducted to investigate the effects of vermiculite, limestone or CaCO3, and combustion temperature and time on desulphurization and dust removal during briquette combustion in small domestic cooking furnaces. Additives used in the coal are vermiculite, CaCO3 and bentonite. Vermiculite is used for its expansion property to improve the contact between CaCO3 and SO2 and to convey O2 into the interior of briquette; CaCO3 is used as a chemical reactant to react with SO2 to form CaSO4; and bentonite is used to develop briquette strength. Expansion of vermiculite develops loose interior structures, such as pores or cracks, inside the briquette, and thus brings enough oxygen for combustion and sulphation reaction. Effective combustion of the original carbon reduces amounts of dust in the fly ash. X-ray diffraction, optical microscopy, and scanning electron microscopy with energy dispersive X-ray analysis show that S exists in the ash only as anhydrite CaSO4, a product of SO2 reacting with CaCO3 and O2. The formation of CaSO4 effectively reduces or eliminates SO2 emission from coal combustion. The major factors controlling S retention are vermiculite, CaCO3 and combustion temperature. The S retention ratio increases with increasing vermiculite amount at 950°C. The S retention ratio also increases with increasing Ca/S molar ratio, and the best Ca/S ratio is 2-3 for most combustion. With 12 g of the original coal, 1 to 2 g of vermiculite, a molar Ca/S ratio of 2.55 by adding CaCO3, and some bentonite, a S retention ratio >65% can be readily achieved. The highest S retention ratio of 97.9% is achieved at 950°C with addition of 2 g of vermiculite, a Ca/S ratio of 2.55 and bentonite.

What do we know about the output effects of fiscal policy in low income countries (LICs)? There are very few empirical studies on the subject. This paper fills this gap by estimating the output effects of government spending shocks in LICs. Our analysis—based on the local projection method—finds that the output effects in LICs are markedly lower than those in AEs and marginally smaller than those in EMs. We also find that in LICs, the output effects are larger (i) during recessions; (ii) under a fixed exchange rate regime; and/or (iii) with higher quality of institutions. Our analysis could not confirm any statistically significant output effect under floating exchange rate regimes. For the estimation of the output effects of fiscal spending shocks, it is thus important to consider the state of the economy and the country’s structural characteristics. Our results imply that the output costs of fiscal adjustment in LICs may not be as large as previously thought, especially if adopted outside of a recession, based on cutting public consumption, and accompanied by reform to enhance institutions.

The purpose of improving a method is to devise a tool for resolving contradictions in the practice of conflict events related to increasing the survivability and effectiveness of participation in a conflict event. A method for forecasting the survivability indicators of a special-purpose system based on the method of analytical-stochastic modeling of a conflict event was chosen as the basis for improvement. The improved method is intended to find a compromise between the need to increase the duration of participation in the conflict and minimize the time of being at risk of loss of ability to function. The use of the improved method, unlike the existing ones, provides an assessment of the impact of maneuver on the effectiveness of the implementation of tasks and the survivability of SPS. The method implies justifying the techniques for the executive elements to maneuver in order to create favorable conditions and effectively perform tasks in a conflict event. The method involves the procedure for the formation of initial data; determining the maneuvering intensity of executive elements; comparing the parameters for expedient (rational) and implemented maneuvering techniques; the generalization of the research results. The accepted indicators of the effectiveness and survivability of a special-purpose system in a conflict event are the mathematical expectations of the number of destructive influences and the number of preserved executive elements as a function of the intensity of maneuvering. The criteria defined for assessing the maneuvering techniques are the greatest values of the increase in efficiency and survivability with the change in the intensity of maneuvering and taking the favorable position by an executive element in a conflict event. The specified method has helped investigate the peculiarities of changing performance and survivability indicators dependent on the intensity of maneuvering and determine the criteria signs for selecting maneuvering techniques. Based on the signs of informativeness and the nature of the mutual influence of the relevant indicators, the advantage of the method is 30 % while the objectivity of taking into consideration significant factors increases by 15 %. Practice needs to predict the consequences of processes of conflicting nature on the grounds of the effectiveness and survivability of its participants

Every time a household is built, there is certainly a hope of achieving happiness, sakinah, mawaddah wa rahmah, which is the purpose of marriage. Divorce can be carried out as an emergency exit, and it is not an urgent thing that must be done, but the most hated of permissible things. Divorce cases in the Religious Courts of Lampung Province increase every year, which shows that the performance of BP4 Lampung has not been optimal. Therefore, it needs to be evaluated scientifically. The objective of this study is to find a form of reconstruction of the work management of BP4 Lampung in building a sakinah family. This study used qualitative research with a descriptive-analytical type. The approach used interviews, documentation, and observation. The work management of the BP4 Lampung in realizing the sakinah family includes: First, the selection of management and organizational members who have spiritual, cultural, and intellectual dimensions; Second, the provision of honorary and social security; Third, training and development or competency development and training. Reconstruction that can be carried out is budgeting, where after the issuance of the law on regional autonomy, then BP4 Lampung, which is a partner of the Ministry of Religion and related agencies in improving the quality of marriage by developing the sakinah family movement, should get attention in the whole budgeting problem by the government, so that this program can be run optimally. To policy makers, both from the legislative and executive elements, along with the scholars, they should be proactive in paying attention to and following up on very complex Muslim problems, especially in the realm of Islamic family law and at the same time damaging the morals and values of the society in general. In this case, the most important problem is the prevalence of divorce practices in Lampung which have a negative impact on the psychological development of families.Setiap terbangunnya rumah tangga, tentunya ada sebuah harapan tercapainya kebahagiaan, sakinah, mawaddah wa rahmah, begitulah tujuan dari perkawinan. Perceraian dapat dilakukan sebagai emergency exit, dan bukanlah hal urgen yang harus dilakukan, melainkan kebolehan yang dibenci. Kasus perceraian di lingkungan Pengadilan Agama Provinsi Lampung tiap tahun meningkat, hal ini menunjukkan bahwa kinerja BP4 Lampung belum berjalan optimal, sehingga perlu dievaluasi secara ilmiah. Penelitian ini bertujuan untuk menemukan bentuk rekonstruksi terhadap manajemen kerja BP4 Lampung dalam membangun keluarga sakinah. Penelitian ini merupakan penelitian kualitatif dengan jenis deskriptif-analitis. Pendekatan yang digunakan menggunakan wawancara, dokumentasi dan observasi. Manajemen kerja BP4 Lampung dalam mewujudkan keluarga sakinah di adalah; Pertama, penjaringan pengurus dan anggota organisasi yang memiliki dimensi spiritual, budaya, dan kecerdasan. Kedua, pemberian honorarium dan jaminan sosial, Ketiga, training and development atau pengembangan kompetensi dan pelatihan. Upaya rekonstruksi yang dapat dilakukan adalah melalui budgeting, di mana pasca lahirnya undang-undang tentang otonomi daerah, maka BP4 Lampung yang merupakan mitra Kementerian Agama dan instansi-instansi yang terkait dalam tugas meningkatkan mutu perkawinan dengan mengembangkan gerakan keluarga sakinah, seharusnya mendapatkan perhatian dalam masalah penganggaran secara utuh oleh pemerintah. Sehingga program ini dapat berjalan dengan maksimal. Kepada para penentu kebijakan, baik dari unsur legislatif maupun eksekutif, beserta para ulama’ agar proaktif dalam memperhatikan dan menindak lanjuti permasalahan umat muslim yang sangat kompleks khususnya pada ranah hukum keluarga Islam dan sekaligus dapat merusak akidah dan akhlak masyarakat secara umum. Di mana, permasalahan terpentingnya adalah, tentang maraknya praktik cerai gugat di Lampung yang berdampak negatif terhadap perkembangan psikologis keluarga.

Abstract The assessment of profit change over time and its drivers is essential to analyse firms' financial performance. This paper investigates profit change and its components for the 10 English and Welsh water and sewerage water companies over the period 1991–2008 and for three regulatory sub-periods. Profit changes and their drivers are computed following two approaches, namely: without controlling for water and sewerage quality issues, and after decomposing the output effect into high quality and low quality output effect. In both cases, profit change is decomposed into various factors such as quantity and price effect, technical change, efficiency change, resource mix, product mix, and scale effect. Profit change over the whole period was negative, with the substantial negative price effect being the main driver, which outstripped the positive quantity effect. This negative profit change was significantly marked from 2000 to 2005 while in the sub-period 1994–2000, which covers the 1994 price review, the profit change was positive. A further decomposition illustrated the significant negative impact of the input price and scale effects on profit changes. The methodology and conclusions of this paper are of great interest for both regulators and water utilities managers to improve future performance.
