The Relationship

Based on the findings in almost all earthquakes that hit Indonesia, the damaged and collapsed buildings were simple houses built spontaneously (non engineered building), where buildings are built based on practical experience without structural calculations. One form of damage to non-structural components and structures is the relationship between columns and brick walls, where cracks and separation between columns and walls occur due to no anchor. So the design of buildings in the future is safe from the dangers of earthquakes. For earthquakes that are not too large, the building is likely to remain standing with little damage. However, to anticipate a strong earthquake and reduce the adverse effects, the building of a walled wall must be built according to the provisions of earthquake-resistant building construction by providing reinforcement in certain parts such as mounting anchors from column to wall. To find out how much influence from the installation of the anchor from the column to the brick wall, an experimental study was carried out on the walls completed with a foundation, sloof, column and beam. There were 2 specimens, namely specimen that uses the anchor and do not use anchor, so it is expected to know the behavior of mounting anchors. From the test results obtained that a pushover load of 7540 kg and a displacement of 56.5 mm for specimens using anchor while for specimens that did not use anchor had pushover 5666 kg and a displacement of 48 mm. The conclusion is the installation of anchors between column and brick wall can increase

Based on the findings in almost all earthquakes that hit Indonesia, buildings that were damaged and collapsed were simple non-engineered buildings. Where buildings are built based on practical experience without structural calculations. One form of damage to non-structural components and structures is the relationship between columns and brick walls, where cracks and separation between columns and walls occur due to lack of anchors (cuttings). To find out how much an earthquake load can make a test object that uses anchor has been destroyed, a pushover analysis is carried out numerically and experimentally. From the numerical results it is obtained a pushover of 7490 kg and a displacement of 16.7 mm, while the experimental results obtained a pushover 7,540 kg and 56.5 mm displacement. Numerical results and experiments are very close at 99.34%.

<p>Environmental-based diseases (PBL) are a health problem and occur in almost all geographical regions in the world. Every year, environment-based diseases are always found and reported to spread evenly at every Puskesmas in Bandar Lampung City. Settlement sanitation is an important aspect directly related to health and society. "Waterborne Disease" disease is still high, proving that there are still sanitation problems in settlements. The study aims to determine the relationship of settlement sanitation with environmental-based diseases in the city of Bandar Lampung. The study used a cross-sectional design, the population is all households in Bandar Lampung City. The sample was 384 respondents, taken randomly using multistage sampling. The results found 14,3% of respondents had a physical component of an unhealthy house, 45,3% of respondents had an unhealthy sanitation facility, 40,1% of the occupants of the house behaved in an unhealthy manner. The test results statistically concluded that there was a significant relationship between settlement sanitation and the incidence of environmental-based diseases.</p>

Currently, rigid pavement in almost all national, provincial and district roads is used instead of flexible pavement. One of the rigid concrete pavement quality controls is the flexural strength (fr = 45 kg / cm2 at 28 days) as stated in the General Specification of Binamarga year 2010 revision 3. This specification no longer regulates the value of compressive strength of the rigid pavement. This is a challenge for the construction’s practicians in implementation of the specification, because during this time the procurement of cement concrete is based on the compressive strength. The formula is in SNI 2847: 2013 on concrete that fr = 0,62Öfc’. While the construction practitioners generally still use the binamarga specifications of previous revisions that contain the quality of concrete (K-350), so that the quality of bending in general is not achieved. This research covers the value of bending test results conducted in the Engineering Laboratory on beams provided by third parties using lab services, as well as test specimens made in the laboratory. The test results show that there is a correlation between the flexure strength to the compressive strength of the concrete. The relationship is more or less the same as the formula contained in SNI concrete.Keywords: Concrete, Flexure strength, compressive strength, Binamarga Specs 2010 rev. 3

Approximately 85 million people's houses are scattered all over Indonesia, and almost all are in strong earthquake areas. In every earthquake, the houses are generally damaged or collapsed. Therefore, those houses must be strengthened to make them earthquake resistant. This paper discusses a gradual strengthening of existing houses using ferrocement bandaging. The gradual strengthening is introduced due to limited funding of the people. It also serves as an educational tool to educate people to be self-sufficient in building their earthquake-resistant houses. The first step, maybe the sleeping room shall be strengthened so that if there is an earthquake during night-time, people will be safe, and if there is an earthquake during the daytime, people can immediately run to that particular room. A global analysis is made of a sample house shaken by Palu, Central Sulawesi earthquake 2018, and West Sumatra earthquake 2009, with one room strengthened to show that the strengthened room can survive the earthquakes. Then the analysis is continued gradually to the other rooms until the masonry house is fully strengthened by ferrocement bandaging. The results show that the masonry house strengthened by ferrocement layers is earthquake resistant.

The status of tafsīr and Qur'anic studies in the Islamic Republic of Iran has changed significantly during recent decades. The essay provides an overview of the state of Qur'anic studies in Iran today, aiming to examine the extent of the impact of studies by Western scholars on Iranian academic circles during the last three decades and the relationship between them. As in most Islamic countries, the major bulk of academic activity in Iran in this field used to be undertaken by the traditional ʿulamāʾ; however, since the beginning of the twentieth century and the establishment of universities and other academic institutions in the Islamic world, there has been increasing diversity and development. After the Islamic Revolution, many gradual changes in the structure and approach of centres of religious learning and universities have occurred. Contemporary advancements in modern sciences and communications technologies have gradually brought the institutions engaged in the study of human sciences to confront the new context. As a result, the traditional Shīʿī centres of learning, which until 50 years ago devoted themselves exclusively to the study of Islamic law and jurisprudence, today pay attention to the teaching of foreign languages, Qur'anic sciences and exegesis, including Western studies about the Qur'an, to a certain extent, and recognise the importance of almost all of the human sciences of the West.

This study was designed to explore the relationship between sunlight exposure and the mechanical properties of paragliding fabrics which have different colors, densities, yarn counts, and coating materials. This study exposed 5 different colors of paragliding fabrics (red, turquoise, dark blue, orange, and white) to intense sunlight for 150 hours during the summer from 9:00 a.m. to 3:00 p.m. for 5 days a week for 5 weeks. Before and after the UV radiation aging process, the air permeability, tensile strength, tear strength, and bursting strength tests were performed. Test results were also evaluated using statistical methods. According to the results, the fading of the turquoise fabric was found to be the highest among the studied fabrics. It was determined that there is a significant decrease in the mechanical properties of the fabrics after sunlight exposure. After aging, the fabrics become considerably weaker in the case of mechanical properties due to the degradation in both the dyestuff and macromolecular structure of the fiber

Parent–adolescent communication is assumed to be an important factor affecting adolescent smoking behavior. However, the inner mechanism accounting for this association has still not been clarified in research. Our purpose in this study was to examine the relationships between parent–adolescent communication, adolescent smoking behavior, and depression, as well as gender differences in the relationship between depression and adolescent smoking behavior. Participants were 1,134 students at 6 junior high schools in China who completed the Parent-Adolescent Communication Scale, the Epidemiological Studies Depression Scale, and the Smoking Behavior Test. Results showed that parent-adolescent communication had a significant negative effect on adolescent smoking behavior and depression partially mediated the relationship between parent–adolescent communication and adolescent smoking behavior. In addition, gender moderated the relationship between depression and adolescent smoking behavior. Overall, these findings may help to promote better understanding of the relationship between parent–adolescent communication and adolescent smoking behavior.

Abstract We perform a lattice study of double parton distributions in the pion, using the relationship between their Mellin moments and pion matrix elements of two local currents. A good statistical signal is obtained for almost all relevant Wick contractions. We investigate correlations in the spatial distribution of two partons in the pion, as well as correlations involving the parton polarisation. The patterns we observe depend significantly on the quark mass. We investigate the assumption that double parton distributions approximately factorise into a convolution of single parton distributions.
