Dark matter models for the 511 keV galactic line predict keV electron recoils on Earth

We propose models of Dark Matter that account for the 511 keV photon emission from the Galactic Centre, compatibly with experimental constraints and theoretical consistency, and where the relic abundance is achieved via p-wave annihilations or, in inelastic models, via co-annihilations. Due to the Dark Matter component that is inevitably upscattered by the Sun, these models generically predict keV electron recoils at detectors on Earth, and could naturally explain the excess recently reported by the XENON1T collaboration. The very small number of free parameters make these ideas testable by detectors like XENONnT and Panda-X, by accelerators like NA64 and LDMX, and by cosmological surveys like the Simons observatory and CMB-S4. As a byproduct of our study, we recast NA64 limits on invisibly decaying dark photons to other particles

Neutrino experiments probe hadrophilic light dark matter

We use Super-K data to place new strong limits on interactions of sub-GeV Dark Matter (DM) with nuclei, that rely on the DM flux inevitably induced by cosmic-ray upscatterings. We derive analogous sensitivities at Hyper-K and DUNE and compare them with others, e.g. at JUNO. Using simplified models, we find that our proposal tests genuinely new parameter space, allowed both by theoretical consistency and by other direct detection experiments, cosmology, meson decays and our recast of monojet. Our results thus motivate and shape a new physics case for any large volume detector sensitive to nuclear recoils

The Factors That Influence the Implementation of Smoke Free Campus Policy in University of Muhammadiyah YOGYAKARTA

Smoking is one of the problems in society today that difficult to resolve. There are 6 million deaths each year are caused by smoking. The number of smokers in Indonesia continues to grow, which is dominated by the age of 15 years and above. To overcome these problems the government issued a policy banning smoking in the learning process. Universitas Muhammadiyah Yogyakarta (UMY) was one of the places that already have implemented smoke-free campus since 2011, but until now there is smoke in campus. This study was to determine the factors that affect the implementation Kawasan Bersih Bebas Asap Rokok (KBBR) in UMY.This study was a qualitative research with phenomenological approach. The data were taken using the method discussion focus groups, depth interviews and observation. Participants in this study were determined by purposive sampling counted 20 participants consisting of students and campus employees in UMY. The validity of the data in this study was done by using triangulation, triangulation methods and peer debriefing. Data analysis was performed with the help of software open code version 4.2. These results indicate that the factors that affect the implementation KBBR in UMY was knowledge of KBBR, attitudes toward KBBR, lack of socialization and prohibition signs of KBBR, the absence of strict sanctions against violators KBBR and environmental influences. This shows that UMY needs to improve socialization and give strict punishment for violation of KBBR

Sikap Mahasiswa terhadap Kebijakan Kampus Bebas Asap Rokok di Universitas Muhammadiyah YOGYAKARTA

Smoking is one of the problems in society that is diicult to be resolved. In 2011, 6 million deaths each year are caused by smoking. The number of smokers in Indonesia continues to grow which is dominated by the age of 15 years and above. To overcome these problems, the government issued a policy of banning smoking in the learning process places. UMY is one of the places that have already implemented smoke-free campus since 2011, however there are people who still smoke in the campus.The purpose of this study was to determine how the students\u27 attitude of Universitas Muhammadiyah Yogyakarta toward a smoke-free campus policy. This studywasaqualitativeresearchwithphenomenological approach. The data was taken using the disccusion focus groups, depth interviews and observation. Participants in this study were determined by purposive sampling which were 20 participants consisting of students and campus employees in UMY. The validity of the data in this study was done by using triangulation, triangulation methods and peer debrieing. Data analysis by using the soft ware open code version 4.2. The results indicated that the students who were active smokers agreed and disagreed on KBBR, nevertheless there are diferences in attitudes related to compliance with these rules. Students who were active smokers who agreed to KBBR supported and there were students who did not support the KBBR. But students who were active smokers that did not agree to KBBR did not support the implementation of KBBR on campus. Unlike the students who were active smokers, passive smokers students all agreed and supported KBBR in UMY. By that attitude, UMY needs to increase their knowledge and socialization of KBBR to the students, therefore the students are able to increase the positive attitude towards KBBR in order to create a clean and smoke-free campus

Peningkatan Suhu Bayi Prematur Melalui Terapi Sentuhan

Mengidentifikasi pengaruh terapi sentuhan terhadap suhu dan nadi bayi prematur di ruang perinatologi RS X Tangerang. Desain penelitian menggunakan kuasi eksperimen dengan pre dan post test. Teknik pengambilan sampel dengan cara consecutive sampling. Responden berjumlah 30 bayi prematur, dengan 15 bayi pada kelompok intervensi dan 15 bayi pada kelompok kontrol. Pengujian rata-rata suhu dan nadi pada kelompok kontrol dan kelompok intervensi menggunakan uji t-test. Hasil penelitian menunjukkan peningkatan rata-rata suhu bayi prematur secara signifikan pada kelompok intervensi (p= 0,000, α= 0,05). Kesimpulannya, terapi sentuhan dapat meningkatkan suhu bayi prematur. Disarankan agar terapi sentuhan dapat diterapkan dalam asuhan keperawatan pada bayi prematur

Oral Health-related Quality of Life Among Pregnant Women at Hospital Universiti Sains Malaysia

This cross sectional study aimed to determine oral health-related quality of life in pregnant women. A total of 100 pregnant women seen at the Obstetrics and Gynaecology Clinic at Hospital Universiti Sains Malaysia participated in this study. The short version of the Malaysian Oral Health Impact Profile (S-OHIP(M)) questionnaire with five-point ordinal scale that ranges from ‘never' to ‘very often' was used to assess the frequency of oral impacts during the previous 12 months. The majority of the respondents were Malay (96.0%), with a mean age of 29.9 years (SD 5.78). The highest education level attained by most respondents was post-secondary qualification or Diploma (39.0%). Some had formal tertiary education (27.0%). The majority of them were income earners (74.0%) and contributed to the household income. Half of the respondents were in their third trimester of pregnancy while the remaining half was either in the first or second trimester. The severity of impact experienced by the women, which is the mean S-OHIP(M) score was high at 10.43 (95% CI = 8.96, 11.90). The prevalence of impact, which is the percentage of respondents reporting ‘fairly often' or ‘very often' to one or more impacts, was 36.0%. Common impacts experienced by the respondents include feeling uncomfortable because food got stuck in between teeth or dentures (22.0%), feeling that oral health problems had caused bad breath (13.0%), and feeling shy because of problems with teeth, mouth or dentures (9.0%). The results also demonstrated that neither the severity nor the prevalence of impact was influenced by the women's socio-demographic background. This study concluded that pregnant women suffered from high impact of oral diseases that could affect their quality of lif
