The Rising Relative Presence of Whites in Majority Non-White Cities

After several decades of Whites fleeing large metropolitan areas, they are now increasingly gentrifying urban neighborhoods and communities. This analysis uses data from the 2000 decennial census and the 2012 and 2017 American Community Survey to assess the growing presence of Whites in U.S. cities. The analysis examines the extent to which Whites have experienced an increase in their percentage share of the populations of 212 majority non-White communities with 50,000 or more inhabitants over two time periods (2000 to 2008–2012 and 2008–2012 to 2013–2017). The results show that 39 communities have experienced an expanding relative presence of Whites in one or both periods. Whites generally are growing at a faster pace than Blacks and Latinos in these communities and there are large socioeconomic gaps favoring Whites. The article concludes with a discussion of the policy implications of the findings.

The effect of different medium chain fatty acids, calcium butyrate, and salinomycin on performance, nutrient utilization and gastrointestinal tract of chicken of Polish Green Legged Partridge hen

The present study aimed to determine the effect of diets supplemented by feed additives, on the growth performance and digestive tract functioning in chicken of green-legged partridge hen (GLPH). Two types of diets were used. The both “low-digestible” (LD) diet characterized by high level of crude fibre and lard, and “high-digestible” (HD) diet characterized by low content of crude fibre and soybean oil were supplemented by different additives such as 0,34% DM (dry matter) salinomycin, 0,30 % DM medium-chain triglycerides (MCT), 1,00 % DM calcium butyrate (CB), or 0,85 % DM medium-chain fatty acids (MCFA). The experiment was conducted on 960 one-day-old male chickens of GLPH, randomly divided into 10 treatment groups. One group consisted of 12 replications (each with 8 birds). Chickens fed HD diet presented significantly higher body weight gain (BWG) in 15-56 days and also 0-56 days of experiment and lower feed conversion ratio (FCR) during whole time (0-56 days) of experiment (P < 0.05). Addition of CB and MCFA did not affect the differences in BWG (15-56; 0-56 days) and FCR (15-56 days) in comparison with the control diet. Significant interaction between the type of diet and additives (P < 0.05) was observed for feed intake (FI) throughout the experiment. The highest FI was found on LD diet with CB. On LD diet, all additives resulted in significantly worse nitrogen retention, however, on HD diet, it was observed only for salinomycin. The additives had no impact on fat digestibility when chickens were fed HD diet. There was significant (P < 0.05) lower-fat digestibility when LD diet with MCT, CB, and MCFA was used. The greatest value of nitrogen-corrected apparent metabolizable energy (AMEN) was found on HD diet (P < 0.05). The addition of MCT, CB, and MCFA increased the percentage share of ileum, and MCT also significantly increased the percentage share of the liver. The lactic acid bacteria and C. perfringens counts were lower on HD diet (P<0,05). The addition of MCT and CB increased the count of lactic acid bacteria in ceaca (P<0,05). Many interactions between experimental factors in this experiment showed that the efficacy of using different feed additives depends on the type of diet. The results suggest that MCFA may be the most beneficial feed additive for GLPH chicken as an alternative for antibiotic growth promoters (AGP).

Exergy analysis and performance study for sour water stripper units, amine regenerator units and a Sulphur recovery unit of a refining plant

A refining column in the middle east that started its official production in 2020 provides its sour wastewater from all refinery plants to two sour water units (SWS1 and SWS2) to strip H2S and NH3. Sour gas from the refinery uses a lean amine solution for gas sweetening to absorb H2S in different absorbers. Rich amine with H2S is then stripped in two amine regeneration units (ARU1 and ARU2). The overhead of SWS and ARU units provide the acid gas feed to the sulphur recovery unit (SRU) to produce sulphur and prevent any acidic emissions against environmental regulations. First, the SWS1 unit is simulated using Aspen HYSYS V.11. A complete exergy study is conducted in the unit. Exergy destruction, exergy efficiency and percentage share in the destruction are calculated for all equipment. The highest exergy destruction rate was in the stripper with 5028.58 kW and a percentage share of 81.94% of the total destruction. A comparison was conducted between the exergy results of this study with two other exergy studies performed in the same refinery plant. The columns in the three studies showed the highest destruction rates exceeding 78% of the total destruction of each unit. The air coolers showed the second-highest destruction rates in their units with a percentage share exceeding 7% of the total destruction. The pumps showed the lowest destruction rates with values of less than 1% of the total destruction of each unit. Then, an individual simulation is conducted for stripper1 of SWS1, stripper2 for SWS2, regenerator1 of ARU1 and regenerator2 of ARU2. The individual simulations are combined in one simulation named combined simulation to compute the composition of acid gas from SWS and ARU units feeding SRU. Then, the SRU unit is simulated via a special package in HYSYS V.11 named SULSIM. The computed composition from SWS and ARU is exported to excel where it is linked with SRU simulation to calculate sulphur production. For the first time in any article in the world, all data feeding SWS, ARU, and SRU units are connected to a live system named Process Historian Database (PHD) to gather live data from the plant and perform plant optimization.

Domestic factors that constraint ecuadorian export performances

Exports play an important role in Ecuador, the income from these contributes to the growth of the economy. This research aims to describe the national factors that limit the performance of Ecuadorian exports. The research was carried out under the inductive method, of an exploratory type with a mixed approach and descriptive scope; the techniques used were the documentary review and semi-structured interview. Data provided by the Central Bank of Ecuador were taken on the growth rate of goods exports and the percentage share of the destinations of goods exports by continent, economic area and country during 2015-2020. The results showed that exports fluctuated and lost competitiveness during the analyzed period. In conclusion, the performance of exports is limited by national factors related to the policies and management of public institutions and procedures.

The tenth part of the Social Change Indicators series gives an account on the living conditions that work as barriers against social distancing in different states of India: This segment especially focusses on aspects, such as the percentage of households (rural and urban) that own a house, the percentage share of nuclear households (rural and urban), the mean number of persons sleeping per room in households, the percentage of households (rural and urban) in which cooking is done in a separate room, the percentage of households (rural and urban) in which water is not treated prior to drinking, the percentage of households (rural and urban) with an improved non-sharable sanitation facility and the proportion of households living in slums.

Health expenditure among the outpatient of type-2 diabetes in selected hospital of Kathmandu district: A cross-sectional study

Introduction Pocket (OOP) expenditure is the dominant financing mechanism in low and middle-income countries. In these countries, the prevalence of diabetes has been rising more rapidly, leading to various microvascular complications, thus increasing the risk of dying prematurely. Methods A cross-sectional - comparative and hospital-based study was carried out in which OOP expenditure of diabetic patients treated in public and private hospitals was compared. A total of 154 diabetic patients i.e.77 in each type of hospital were selected purposively in consultation with attending physicians and staff. Face to face interview was done on a diabetic patient with a minimum of one year of illness using a structured questionnaire. Lorentz curve and concentration curve were prepared using the income and expenditure of the patients. Result Among 154 patients, 97.4% of patients had paid out of pocket for the treatment of diabetes. The mean direct cost per month was NRs. 7312.17 in public and NRs. 10125.31 in a private hospital. The direct medical cost had a higher share in total direct cost i.e. 60.5% in public and 69.3 % in a private hospital. Medicine cost had a higher percentage share (50.9%) in public hospital and laboratory cost had a higher percentage share (68%) in a private hospital. Conclusion The direct medical cost was higher in a private hospital as compared to a public hospital. All the income groups have to pay a similar amount of money for the treatment i.e. economic burden for the treatment of disease was found higher for the poor people as there was no financial protection mechanism.

The Impact of Legal Systems on Dividend Payments

This paper focuses on the amount of dividends paid to shareholders by companies in different countries and examines whether being in a country where the legal system offers weak shareholder protection affects dividend payments distributed to shareholders. The sample used for this study comprises 8,045 companies from 46 countries. Seven individual factors affecting shareholder protection were examined. Out of the seven factors, only two of them provide a significant relationship with dividend payments, and more specifically, the mechanisms put in place by companies to protect oppressed minority shareholders as well as minimum percentage share of capital in order for the shareholders to be eligible to call an extraordinary shareholder meeting.

Morphological characteristics and correlation dependences among quantitative indications in bird's foot trefoil cultivars

PURPOSE of the present study was to make a morphological analysis and calculate correlations among yield and quantitative indicators. METHODS: It was based on the blocking method in 4 replications with a plot size of 5 m2 with the following bird's foot trefoil cultivars: Targovishte 1, Alvena, Lotanova and Frilo, Polom, Bonnie, Bull. RESULTS: It was found that the share of stems in grasslands was higher than the leaves, and the degree of variation in this indicator was low. Lotanova cultivar was the most productive with a registered dry matter yield of 1061.55 kg/da. The maximum share in grassland was realized by Alvena cultivar (73.8%), and the tallest stems were registered for Targovishte 1. CONCLUSIONS: Parameters correlating with high values are dry matter yield and the percentage share of bird's-foot-trefoil in the grassland (r = 0.6816).

AN ANALYTICAL STUDY OF MONTHLY TURNOVER AND COST STRUCTURE OF RUBBER INDUSTRY IN KERALA

The present paper is an attempt to examine the monthly turnover and the cost structure of Rubber Industry in Kerala. The study of monthly turnover and the cost structure of Rubber Industry in Kerala are very important and much significant for the Rubber industry in Kerala. The researcher prepared a questionnaire keeping in mind all the important aspects related to indigenous rubber and import of rubber. The present study is based on primary data. Primary data was collected from the Rubber industrial units (Sole Proprietor, Firm and Company) from three regions of Kerala i.e., Southern Region, Central Region and Northern Region through a structured questionnaire. Questionnaire was constructed after consulting the experts in the field of Rubber industry. Based on their suggestion, some items were deleted and some items were modified. The responses of the users were, by and large, encouraging. They responded freely in highlighting different aspects of rubber industry. To conclude, there is significant difference in the monthly turnover for different Rubber Industrial Units in Kerala. In other words, we can say that as nature of ownership changes, there is a change in monthly turnover. Likewise, the percentage share of different components of cost namely overhead cost and fixed cost of Rubber Industry in Kerala based on ownership is different and it is found more for sole proprietorship and firm respectively. The percentage share of different components of cost of Rubber Industry in Kerala based on operation is same. KEY WORDS: Monthly turnover, Cost structure, Rubber Industry, Overhead cost, Fixed cost.
