Phosphorus removal in domestic wastewater treatment plant by calcined eggshell
Authors: Fritzen Rafael Renato , Benetti Antônio Domingues 
Published: July 2021

Abstract
Recovery of phosphorus (P) from wastewater is a topic of great interest. Besides being a non-renewable resource, P discharge in receiving waters can trigger algae blooms. The present study aimed to quantify the removal of P from two sites at a wastewater treatment plant using calcined eggshell (CES) as adsorbent. CES was prepared from raw shells calcined at 600 °C (CES600) and 800 °C (CES800). CES at 800 °C proved to be an efficient material for P removal. Efficiencies greater than 70% were achieved using CES800 concentrations of 0.1 g L−1 for synthetic sample, 0.3 g L−1 for preliminary treated wastewater and 20 g L−1 for supernatant from sludge anaerobic digester. The adsorption process was fast, occurring mostly in the first 30 min. Both Langmuir and Freundlich isotherms fitted the experimental data on adsorption. In kinetic experiments, a pseudo-second-order model fitted P adsorption from synthetic, preliminary effluent and digester supernatant. Thermogravimetric analysis showed a 54% eggshell mass loss at 800 °C. Calcination increased calcium and reduced carbon fractions in the eggshells, while increasing the surface area.

Published: July 2021

Background:
After the official operation of the Jakarta-Cikampek elevated highway, a socio-demographic picture of Indonesian travel passengers, as well as their interest in switching transportation preferences was provided. This elevated highway shortened travel time and discouraged users from changing to other transportation modes. This study is likely to become a future research foundation for the switching behavior of passengers.

Objective:
This study aims to analyze demographic factors and interests on passenger’s switching of transportation preference.

Methods:
A total of 720 questionnaires were distributed to land transportation passengers at concentrated points with a response rate of 89.17% and 642 valid answers. The obtained data were analyzed using quantitative descriptive techniques with cross tab methods.

Results:
The results showed that age, education level, and type of work influenced the desire of passengers to switch transportation modes, as opposed to gender. Most of the passengers interested in using land modes, such as the highway, were dominated by intercity between provinces travel buses and refused to change to other means of transportation. Meanwhile, passengers that used rented cars tended to switch to other forms of transportation.

Conclusion:
This research is useful and acts as a reference for managers of each transportation mode to set high priorities for particular consumers based on detailed socio-demographics to retain or attract new potential customers.

Archeologie voor snackers, ondiepe gravers en diepgravers: de archeoloog als verhalenverteller
Authors: Wolters Harrie 
Published: July 2021

Archaeology for ‘paddlers’, ‘swimmers’ and ‘divers’. This article gives a brief outline of the numerous ways in which people can get involved in archaeology. The most important message is the idea that archaeology revolves around ‘storytelling’; the archaeologist is a person who tells stories about the past. This approach can be used to appeal to three target groups: ‘paddlers’, ‘swimmers’ and ‘divers’. The article is written by a director of the Hunebedcentrum, a museum which has more than 50 years’ experience of telling stories to a wide public. It is an example of ‘archaeology for all,’ an approach that can also be applied to other activities in which archaeology has a role to play. The world has changed rapidly over the past 25 years. New media, such as smartphones, drones, audio-visual equipment and other technology, mean that the world can be experienced in a completely different way today than it could in the past. There are wonderful opportunities available to those who are receptive to new ideas. A subject such as archaeology, which stimulates people’s imagination, is particularly suitable in this context.

Objective: to study clinical, anamnestic, and laboratory parameters in children with acute and chronic urticaria.Materials and methods: fifty-five children were examined who were admitted to the pediatric department and day-time inpatient facility of the State Children’s Clinical Hospital No. 17 in Ufa in 2019. Two groups were formed: 44 patients with acute urticaria (Group 1) and 11 patients with chronic urticaria (Group 2). For the correct analysis of the hemogram and immunogram, 2 subgroups of patients with acute urticaria were formed: Group 1a – 13 children under 5 years old and Group 1b – 31 children over 5 years old.Results: acute urticaria was typical for young children (Z cor. = -2.14665; p = 0.031822). In children with acute urticaria under five years of age, there was a correlation (p < 0.05) of age with low serum JgA levels (rs = 0.806380) and the incidence of gastropathology with JgM levels (rs = 0.872872); JgG (rs = 0.763763) and the number of blood leukocytes (rs = 0.692820). In children with acute urticaria over five years of age, a correlation was found between age and concomitant gastropathology (rs = 0.421569). Patients with chronic urticaria are characterized by eosinophilia (Z cor. = -2.96741; p = 0.003003) and a pathogenetically significant increase in the CEC level (Z cor. = 1.98537; p = 0.047104).Conclusion: the revealed differences should be taken into account during the examination and management of children with urticaria.

Background
With the prolonging of human life expectancy and subsequent population aging, osteoporosis (OP) has become an important public health issue.

Objective
This study aimed to understand the global public search interests and dynamic trends in “osteoporosis” using the data derived from Google Trends.

Methods
An online search was performed using the term “osteoporosis” in Google Trends from January 1, 2004, to December 31, 2019, under the category “Health.” Cosinor analysis was used to test the seasonality of relative search volume (RSV) for “osteoporosis.” An analysis was conducted to investigate the public search topic rising in RSV for “osteoporosis.”

Results
There was a descending trend of global RSV for “osteoporosis” from January 2004 to December 2014, and a slowly increasing trend from January 2015 to December 2019. Cosinor analysis showed significant seasonal variations in global RSV for “osteoporosis” (P=.01), with a peak in March and a trough in September. In addition, similar decreasing trends of RSV for “osteoporosis” were found in Australia, New Zealand, Ireland, and Canada from January 2004 to December 2019. Cosinor test revealed significant seasonal variations in RSV for “osteoporosis” in Australia, New Zealand, Canada, Ireland, UK, and USA (all P<.001). Furthermore, public search rising topics related to “osteoporosis” included denosumab, fracture risk assessment tool, bone density, osteopenia, osteoarthritis, and risk factor.

Conclusions
Our study provided evidence about the public search interest and dynamic trends in OP using web-based data, which would be helpful for public health and policy making.

Background
Diabetic kidney disease (DKD) is one of the main complications of type 2 diabetes mellitus (T2DM). DKD is a known risk factor for end-stage renal disease, cardiovascular disease, and all-cause death. Effective intervention for early-stage DKD is vital to slowing down the progression of kidney disease and improve prognoses. Mobile health (mHealth) is reportedly effective in supporting patients’ self-care and improving glycemic control, but the impact of mHealth on DKD has yet to be shown.

Objective
The purpose of this study is to evaluate the efficacy of standard therapy with the addition of a self-management support system, DialBetesPlus, in patients with DKD and microalbuminuria.

Methods
This study is a prospective, randomized, open-label, multicenter clinical trial. The target population consists of 160 patients diagnosed with T2DM accompanied by microalbuminuria. We randomly assigned the patients to 2 groups—the intervention group using DialBetesPlus in addition to conventional therapy and the control group using conventional therapy alone. DialBetesPlus is a smartphone application that supports patients’ self-management of T2DM. The study period was 12 months, with a follow-up survey at 18 months. The primary outcome was a change in albuminuria levels at 12 months. Secondary outcomes included changes in physical parameters, blood test results (glycemic control, renal function, and lipid metabolism), lifestyle habits, self-management scores, medication therapy, and quality of life.

Results
The study was approved in April 2018. We began recruiting patients in July 2018 and completed recruiting in August 2019. The final 18-month follow-up was conducted in March 2021. We recruited 159 patients and randomly allocated 70 into the intervention group and 61 into the control group, with 28 exclusions due to withdrawal of consent, refusal to continue, or ineligibility. The first results are expected to be available in 2021.

Conclusions
This is the first randomized controlled trial assessing the efficacy of mHealth on early-stage DKD. We expect that albuminuria levels will decrease significantly in the intervention group due to improved glycemic control with ameliorated self-care behaviors.

Authors: Abdulahanaa Abdulahanaa 
Published: July 2021

Religious tourism objects in Indonesia are attractive destinations and have the potential to be fully developed. This study is an analysis of Islamic economic law on the arrangements of religious tourism in Indonesia, especially in South Sulawesi. The research method used to examine this problem is field research, utilizing interview, questionnaire, and observation techniques. This study concludes that there are dimensions of Islamic economic law in setting religious tourism. Although there is a difference of opinion on whether or not religious tourism is allowed, it should be noted that religious tourism provides benefits such as increasing the country’s foreign exchange income and developing the community economy. Thus, it is necessary that the government makes regulations that emphasize the purpose of opening religious tourism to the public, including the rights and obligations of managers and visitors, as well as relevant warnings and signs. The regulations have multiple functions, including to improve the economy, to increase the number of visitors, to guarantee the protection of the right to access while maintaining the teachings of their respective religions, to eliminate doubts about the occurrence of deviations of purpose, and to strengthen inter-religious unity. The concept that can be carried out in managing religious tourism objects of different religions is by making rules that integrate arrangements for the benefit of fostering inter-religious relations so as to create harmony in a Pancasila-based society. In the study of Islamic economic law, the arrangements of religious tourism objects will have an impact on creating harmony between religious communities, increasing people’s income, opening up employment opportunities, and strengthening the unity of the nation and the people.
The Roles of Families in Combating Drugs Uses, Violence and Terrorism
Authors: Nasution Khoiruddin 
Published: July 2021

This paper aims to strengthen the opinion or the concept suggesting that family roles are significant in the attempt to overcome drug uses, violence and terrorism in Indonesia. This is a qualitative research, in which sources of data were literary works, such as academic books and articles. The article refers to Berger’s theory of social construction during the first stage in the process of externalization out of three stages: externalization, objectification and internalization, which lead to transformation of social actions, which then shape people’s habits. Meanwhile, in the effort to control Social Actions or control people’s habits, the article refers to preventive and repressive efforts, while in terms of the process of social control; the article refers to persuasive, coercive and curative efforts. Our findings suggest that three main social problems: first, drug uses, violence against children, wives, and husbands and terrorism are still main social problems in Indonesia, which require serious, substantial and sustainable efforts to find effective solutions.However, population growth also needs attention even though it is not as vital as others mentioned earlier; second, there are several important reasons and/or factors that problem of drugs, violence and terrorism persist in Indonesia, one of which is the failure of the family to take important role in guiding its members;third, based on our reviews of literature, we conclude that to maximize roles of family, marriage couples should be knowledgeable and competent in keeping their family runs well. For that reason, it is paramount important for marriage couples to educate themselves regarding their roles and responsibilities within the family life. This can be done through taking the pre-marriage courses for those who are about to get married. In fact, marriage couples should persistently educate themselves through many means and channels.

Authors: Vourdoubas John 
Published: July 2021

Clean energy transition in islands is important and urgent in the current era of climate change. The possibility of de-carbonizing the heating and cooling sector in the island of Crete, Greece has been investigated. Fossil fuels are used in Crete in electricity generation, in heat and cooling production as well as in transportation. The use of various renewable and non-renewable fuels as well as the technologies used in heat and cooling generation has been examined together with the annual changes in fossil fuels consumption during the last years. Various renewable energies like solar energy, biomass and low enthalpy geothermal energy combined with renewable electricity could cover all the heating and cooling requirements in Crete totally eliminating the use of fossil fuels. Their technologies are mature, reliable, and cost efficient. Renewable and low cost electricity can be easily generated by the abundant solar and wind energy resources in Crete powering electric systems generating heat and cooling. Current work indicates that the heating and cooling sector in Crete can be de-carbonized. This would result in the mitigation of climate change complying with the European goal for carbon neutrality in Europe by 2050.
