The Information Content of Target Price Forecasts: Evidence from Mergers and Acquisitions

This paper investigates the informativeness and value relevance of analyst target prices in the context of mergers and acquisitions (M&amp;A). Our results indicate that firms with high 12-month ahead target prices relative to current stock prices are more likely to become a takeover target and offer premium and acquirers’ announcement returns are positively associated with firms’ target price premium. We also show that a long-short trading strategy formed on target prices and firms’ takeover likelihood generates economically significant returns. Our results are robust to a battery of additional analysis, and the informativeness of target prices is not subsumed by other analyst-forecast outputs such as earnings forecasts and recommendations. Overall, our findings suggest that analysts convey valuable information through target price forecasts, which are useful for participants in the corporate takeover markets.
Breakthrough Analysis OF H 2 S removal on CU-V-MO, CU-V, and CU-MO mixed oxides

Kinetic studies carried out for the sorption of H 2 S in the presence and absence of hydrogen on Cu-V-Mo, Cu-V, and Cu-Mo mixed oxides gave detailed information about the reaction sequences. Formation of SO 2 even in the presence of hydrogen at the initial stages of the sorption process showed the partial reduction of the metal oxides prior to the sulfidation step. A sorption experiment carried out with Cu-Mo mixed oxide gave incomplete sulfidation of molybdenum, whereas with Cu-V mixed oxide complete sulfidation was obtained. Predictions of the breakthrough curves by the deactivation model showed good agreement with the experimental results.
How frequent is natural cloud seeding over Switzerland?

Abstract. Clouds and cloud feedbacks represent one of the largest uncertainties in climate projections. As the ice phase influences many key cloud properties and their lifetime, its formation needs to be better understood in order to improve climate and weather prediction models. Ice crystals sedimenting out of a cloud do not sublimate immediately but can survive certain distances and eventually fall into a cloud below. This natural cloud seeding can trigger glaciation and has been shown to enhance precipitation formation. However, up to date an estimate of its occurrence frequency is lacking. In this study, we estimate the occurrence frequency of natural cloud seeding over Switzerland from satellite data and sublimation calculations. We use the DARDAR satellite product between April 2006 and October 2017 to estimate the occurrence frequency of multilayer cloud situations, where a cirrus cloud at T The high occurrence frequency of seeding situations and the survival of the ice crystals indicate that the seeder-feeder process and natural cloud seeding are widespread phenomena over Switzerland. This hints to a large potential for natural cloud seeding to influence cloud properties and thereby the Earth's radiative budget and water cycle, which should be studied globally. Further investigations of the magnitude of the seeding ice crystals' effect on lower lying clouds are necessary to estimate the contribution of natural cloud seeding to precipitation.
Influence of Gender and Environment on the Occurrence of Chronic Obstructive Pulmonary Disease: Cross-Sectional Study

Background and Objective: Chronic obstructive pulmonary disease (COPD) is predicted to be the third leading cause of death worldwide by 2020. Its diagnosis remains a challenge in developing countries such as DRC, with the use of Gold standard, spirometry, limited. Chest imaging plays an important role in orientation. The absence of local radiological data from COPD had therefore motivated this study. The aim of this study is to establish a relationship between gender, environment and COPD. Materials and Methods: Retrospective and analytical study of clinical and thoracic imaging data (radiography and CT scan), collected from the records of 120 COPD subjects followed in three Kinshasa medical trainings between January 2014 and June 2017. Fisher's test compared the results obtained. The combination of imaging data and clinical phenotype through Pearson chi-square testing, logistic regression and odds-ratio (OR). The service threshold was set at 0.05. Results: the study population (average age of 64.52±6.82 years) was predominantly male (78.3% n=94). Results: the study population (average age of 64.52±6.82 years) was predominantly male (78.3% n=94). The proportions of sputum were more common in men than in women, the difference being statistically significant. Indeed, the male sex confers a triple risk (OR=3.1; IC 95% 1.2-8; P=0.015). Women were more exposed to domestic and/or occupational pollution (65.4% n=17; than men were (26.6% n=25). Indeed, the male sex conferred a risk of exposure to domestic pollution and/or occupational pollution multiplied by 14 times (OR=14.3; IC 95%; 2-100; P=0.001) and allergy conferred a risk of exposure to domestic pollution by 17 times (OR=17.1; IC95%: 2.1-137, p=0.007). Conclusion: This study showed the male sex and allergy is conferred a high risk of the domestic pollution or occupation pollution.

Learning to Navigate a New Financial Technology: Evidence from Payroll Accounts

How do inexperienced consumers learn to use a new financial technology? We present results from a field experiment that introduced payroll accounts in a population of largely unbanked factory workers in Bangladesh. In the experiment, workers in a treatment group received monthly wage payments into a bank or mobile money account while workers in a control group continued to receive wages in cash, with a subset also receiving an account without automatic wage payments. We find that exposure to payroll accounts leads to increased account use and consumer learning. Those receiving accounts with automatic wage payments learn to use the account without assistance, begin to use a wider set of account features, and learn to avoid illicit fees, which are common in emerging markets for consumer finance. The treatments have real effects, leading to increased savings and improvements in the ability to cope with unanticipated economic shocks. We conduct an additional audit study and find suggestive evidence of market externalities from consumer learning: mobile money agents are less likely to overcharge inexperienced customers in areas with higher levels of payroll account adoption. This suggests potentially important equilibrium effects of introducing accounts at scale.

Biomass and radiation use efficiency in Eucalyptus plantations as affected by spacing of planting

Spacing of planting is one of the most important silvicultural decisions to be made during implementation of forest stands. The objective of this study was to evaluate the influence of spacing of planted trees on biomass production and solar radiation use efficiency in a Eucalyptus forest plantation in southern Brazil. A field experiment was conducted from September 2008 to September 2017 in the city of Frederico Westphalen, State of Rio Grande do Sul, Brazil. In this study, we evaluated the influence of the spacing of trees on solar radiation use efficiency, interception of solar radiation, leaf area index, biomass yield, and partitioning in the Eucalyptus forest plantation. The conversion efficiency of the photosynthetically active radiation intercepted in the biomass was manipulated by changing the spacing of the trees, and the highest conversion efficiency was 0.0062 kg MJ−1 for the 2.0 × 1.5 m planting spacing. Eucalyptus trees grown on the 2.0 × 1.0 m planting spacing showed the highest biomass yield with 961.4 Mg ha−1, showing that the most efficient plants in the conversion of photosynthetically active radiation are not always the most productive. As a result, the hypothesis of this study was confirmed. Forest managers can accelerate growth and increase the production of forest biomass by adequately manipulating the spacing between the trees.
Comparative Study of Some Layered Hydroxide Salts Containing Exchangeable Interlayer Anions

Abstract Anion-exchange reactions of layered Zn, Cu, Ni, or La hydroxide nitrates with the organic anions acetate, terephthalate, and benzoate are compared. Powder X-ray diffraction (PXRD), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetry combined with mass spectrometry (TG–MS) are used to characterize the materials. Exchange of the interlayer nitrate anions for these organic anions is generally possible, although no exchange is observed for the parent nickel hydroxide material. The organo derivatives obtained may be considered inorganic–organic hybrids, consisting of alternating hydroxide and A− layers, where A is the incorporated organic anion. The materials are structurally similar to the layered double hydroxide family of materials, which also exhibit an anion-exchange capacity.
Bio-based shape memory polyurethanes (Bio-SMPUs) with short side chains in the soft segment

One of the obvious shortcomings of bio-based shape memory polyurethanes (Bio-SMPUs), which usually use natural oil based polyols as the soft segment, is their low mechanical strength because the long dangling chains (six to eight carbons) in these polyols prevent the Bio-SMPUs from deep micro-phase separation, and consequently deteriorate their mechanical properties. In this work, we prepared a bio-based polyester diol for the soft segment, in which short side chains (CC) were used to tune the transition temperature and the morphology of the Bio-SMPUs. The moderate concentration of short branch chains barely affects the micro-phase separation, and the mechanical properties of the Bio-SMPUs are quite satisfactory. With the same 70 wt% soft segment content, the tensile strength in this work is 13.2 MPa, while the one using ricinoleate-based soft segments reported 2.8 MPa. Through proper shape memory programming, the synthesized Bio-SMPUs show good shape memory properties with a shape fixing rate of greater than 98% and a shape recovery rate of 85% in the first cycle and greater than 90% in the following cycles. This study provides a framework for developing bio-based SMPUs with high mechanical and good shape memory properties at the same time.
Nurses and Patients’ Perspectives of Psychosocial Nursing Care Provision to Diabetes Patients in Fako, Cameroon

Aim: The purpose of this study was to identify the psychosocial problems of diabetic patients and to find out, from both nurses and patients, how nurses render psychosocial care to these patients. Methods: A purposive sampling strategy whereby all nurses and patients who met the inclusion criteria were recruited for the study. Questionnaires were administered to both nurses and diabetic patients in the medical, surgical and diabetic units in the study hospitals. Data were analysed using SPSS version 21. Results: 52 nurses and 90 patients participated in this study. The major psychosocial problems of diabetic patients included financial worries (86.7%), fear of developing a complication (66.7%), and diet regulatory difficulties (57.8%). Both nurses (63.5%) and patients (63.5%) agreed that nurses Original Research Article Bassah et al.; AJRNH, 3(4): 41-47, 2020; Article no.AJRNH. 62081 42 always educate patients about their disease condition. However, while nurses reported always assessing presence of support from family members of patients (44.2%) and empowering patients’ family to support patients through counselling sessions (57.8%), most patients (76.7%) reported that this was never the case. Moreover, although many nurses (38.5%) reported that they always assessed patients’ financial ability to pay hospital bills and other treatment needs, more than half of the patients (53.3%) said this was never done. Conclusion: Diabetic patients in these care centres do have psychosocial problems, which needs to be addressed by nurses. Both nurses and patients’ reports generally suggests a minimal provision of psychosocial care to diabetic patients by nurses. Nurses often asses patients to identify these problems, but do not adequately address them. Thus, there is need for improvement in nurses’ provision of psychosocial care for diabetics in the study centre.
Study on characteristics of silicon nanocrystals within sol–gel host

In this article, luminescent Si nanocrystalline (NC) powder was uniformly dispersed in dimethyl sulphoxide and then incorporated into the SiO2 gel matrix. Inorganic precursor tetraethylorthosilane was diluted in ethanol to form a homogenous solution. Dimethylformamide was used as a drying control chemical additive. Absorption and emission spectra of Si NPs in the silica gel with respect to time were recorded systematically at room temperature. The study reveals that the absorption and emission spectra of Si NPs, when doped in sol–gel silica matrix are modified. Influence in the band strengths and their peak positions upon ageing time are discussed. TEM shows existence of Si NPs of size ranges from 5 to 10 nm. Si NCs-doped sol–gel cylindrical rod was prepared and cut at different lengths from 10 to 15 mm to measure the optical gain. Photoluminescence stability of Si NCs in sol–gel is found for several weeks under the UV lamp.
Can common mycorrhizal fungal networks be managed to enhance ecosystem functionality?

Several studies conducted in controlled environments show that key functional at tributes of common mycorrhizal networks (CMNs), which inter-link different plants, are influenced by management practices. Here, we highlight the need to consider how land management affects the ubiquity and function of CMNs in nature to maximize the role of mycorrhizal fungi in enhancing ecosystem services. We emphasize that CMNs can sometimes negatively affect aspects of plant performance, but there remain major gaps in understanding before explicit consideration of CMN management can be delivered. a mycorrhizal influence establishment, nutrition, productivity and defense, nutrient distribution and storage, and multitrophic interactions. However, many of these studies have focused on the importance of common mycorrhizal networks in ecological contexts and there has been less emphasis in managed systems, including croplands, grassland, agrofor estry and forestry, on which humankind relies. Here we review the evidence of the potential importance of common mycorrhizal networks in managed systems, and pro vide insight into how these networks could be managed effectively to maximize the functions and outputs from managed systems. We also emphasize possible negative effects of common mycorrhizal networks on plant performance and question popu lar views that mycorrhizal networks may offer a panacea for enhancing ecosystem services. We highlight the need to gain greater insight into the ubiquity, functioning, and response to management interventions of common mycorrhizal networks and, critically, the need to determine the extent to which these networks can add value to the promotion of mycorrhizal colonization.
Application of LIX 84 for separation of copper, nickel and cobalt in ammoniacal leaching of ocean nodules

The ammoniacal leaching is apparently considered an attractive approach to process polymetallic sea nodules wherein copper , nickel and cobalt are solubilised forming the ammine complexes . To separate these metals, LIX 84, an oxime extractint , was tried from the synthetic solutions . The loading capacity of this solvent for individual metal and ammonia extraction was determined and compared with that of LIX 64N. Preferential extraction of copper over nickel from a mixed aqueous solution was observed . The kinetic studies for the extraction of metals were undertaken to arrive at the retention time appropriate for this operation . Before metal stripping, the mode of ammonia scrubbing from the organic was worked out using acid or a comhination of ammonia -dilute acid as the reagents . The coextraction of nickel and copper and their selective stripping were considered to explore the possibility of separating Cu, Ni and Co from ammonia- ammonium carbonate medium . The separation of these metals from the ammoniacal leach liquor of sea nodules was also attempted.
Relationship between the structure of C60 and its lubricity: A review

Based on analyses of the calculations of quantum theories, such as electron charge density, the energy level distribution of orbitals, and the forces between C atoms and between the molecules in C60 crystals, the author concludes that C60 crystal is a promising solid lubricant. Furthermore, owing to the unique spherical structure of its molecules, high chemical stability, and the phase transition of the crystal fullerene C60 may have some particular tribological properties that are superior to traditional graphite and MoS2, especially under crucial conditions such as high vacuum, high pressure or in a humid environment. The tribological tests that have been reported show the lubricity of fullerene C60, and the effects of the lubricating properties of C60 on some metals are also predicted.
Treatment of food industry effluents ‐ activated sludge versus aerated submerged biological filters

Abstract A mixed wastewater from different food‐processing industries has been treated in two pilot‐plants. One plant was an activated sludge unit, the other was an aerated submerged biological filter with a high surface area plastic medium of 230 m /m . The biofilter was found to be about four times as efficient as the activated sludge unit, based on volumetric removal rates.
State-of-the-Art on Instant Release of Fission Products From Spent Nuclear Fuel

Within the EURATOM FP7 Collaborative Project “Fast / Instant Release of Safety Relevant Radionuclides from Spent Nuclear Fuel (CP FIRST-Nuclides)”, a State-of-the-Art Report was prepared. The fast / instant release fraction (IRF) is defined as a fraction of the inventory of radionuclides that may be rapidly released from the fuel and fuel assembly materials at the time of canister breaching. In the context of safety analysis for a repository, the time span for mobilization of this fraction can be considered instantaneously, even if the process takes some time in experiments. Radionuclides contributing to the fast release are fission gases (Kr and Xe), easily soluble elements such as cesium and iodine, and other elements which are hardly incorporated in the UO2 crystal lattice.The present contribution summarizes the results obtained from published studies focused on rapid release experiments carried out with different spent nuclear fuel (SNF), samples, sizes, techniques (batch and flow-through), and durations. A total of 80 experiments cover the study of UO2 SNF from pressure water reactors (PWR) of different initial enrichments and burn-up, while 20 experiments were performed with UO2 SNF from boiling water reactors (BWR) and 8 with MOX fuel.Copyright © 2013 by ASME

The sample used was 11 Islamic banks in Indonesia which were listed on the Indonesia Stock Exchange and consistently published financial statements and corporate social responsibility reports for the period 2012-2018. The analysis of this study uses the multiple regression method (multiple regression). The results of the study explained that Profitability, Fundings and Financing together have a significant positive effect on CSR (Corporate Social Responsibility). Constraints that are still commonly found in the implementation of CSR are cost issues, competent human resources, distribution of activities and determination of targets, forms of activities, licensing and regulatory issues, lack of partnerships, socialization of activities, understanding of implementation and evaluation in the field, and many persons who carry out illegal levies on the ground .
Water footprint assessment of handwoven silk production

The objective of this study was to determine the magnitudes of the water footprints throughout the production chain of silk. This research is divided into two parts: the agriculture of mulberry cultivation and the handwoven silk production process. The research results revealed that the highest water footprint for 2019 was 1710 cubic metric/tonne, which was greater than the highest water footprint for 2018 of 1125 cubic metric/tonne. For the handwoven silk products, the blue water footprint, grey water footprint, and total water footprint were 445,156, and 601 litres/kg, respectively. The water footprint of one silk shirt was calculated backwards from the handwoven silk production process as 376 litres. Thailand, the world’s largest native handwoven silk product exporter must have a strategy to promote the silk industry’s competitiveness on the world market. Policies stating that farmers, entrepreneurs, government agencies and private organisations should be prepared to address eco‐friendly trends for sustainable production and consumption are also recommended.
