Faktor-Faktor Yang Mempengaruhi Kekuatan Mampatan Terhadap Prisma Bata Tanah Liat Bakar
Disertasi ini mempersembahkan kajian makmal terhadap parameter yang
mempengaruhi kekuatan mampatan terhadap prisma bata tanah liat bakar iaitu;
nisbah kelansingan, ketebalan sambungan mortar, jenis mortar dan tempoh
pengawetan. Bata kejuruteraan jenis SK-30 telah dipilih sebagai bahan utama
kajian. Hasil keputusan menunjukkan perbezaan parameter memberikan kesan yang
nyata terhadap kekuatan mampatan prisma bata. Kesan nisbah kelansingan
menunjukkan, kekuatan mampatan prisma bata berkurang apabila ketinggian
prisma meningkat daripada 2 hingga 3.3, dan prisma bata yang mempunyai nisbah
kelansingan, h/t =2 memberikan nilai kekuatan mampatan yang paling tinggi.
Ketebalan ikatan prisma bata 10 mm memberikan nilai rintangan terhadap kekuatan
mampatan yang tinggi berbanding ketebalan ikatan 15 mm. Nisbah campuran
mortar jenis (i) memberikan nilai kekuatan mampatan yang paling tinggi. Kekuatan
mampatan prisma bata meningkat dengan masa daripada hari ke 14 hingga hari ke
28. Antara faktor lain yang mempengaruhi kekuatan mampatan prisma bata ialah
kadar serapan awalan bata. Hasil keputusan menunjukkan nilai kadar serapan
awalan unit bata ialah 4.31 g/min.30mm2
Hamka’s tasauf modern: an outlook on happiness
Introduction
Hamka (1908-1981)’s Tasauf Modern (Modern Sufism) first
published in August 1939 was a compilation of an earlier year and
a half series of articles on ‘happiness’ from the weekly columns of
the magazine Pedoman Masjarakat (Guidance for Society) where
he was its chief-editor. The first article which appeared through
the magazine’s circulation, dated 21st April, 1937, came with the
reminder from the author, that he was writing in response to
the requests of the magazines’ faithful followers, especially the
elderly who had gone through so much of life’s hardships (pahitgetir).
Characteristics and outcomes of COVID-19 patients admitted to hospital with and without respiratory symptoms
Background: COVID-19 is primarily known as a respiratory illness; however, many patients present to hospital without respiratory symptoms. The association between non-respiratory presentations of COVID-19 and outcomes remains unclear. We investigated risk factors and clinical outcomes in patients with no respiratory symptoms (NRS) and respiratory symptoms (RS) at hospital admission. Methods: This study describes clinical features, physiological parameters, and outcomes of hospitalised COVID-19 patients, stratified by the presence or absence of respiratory symptoms at hospital admission. RS patients had one or more of: cough, shortness of breath, sore throat, runny nose or wheezing; while NRS patients did not. Results: Of 178,640 patients in the study, 86.4 % presented with RS, while 13.6 % had NRS. NRS patients were older (median age: NRS: 74 vs RS: 65) and less likely to be admitted to the ICU (NRS: 36.7 % vs RS: 37.5 %). NRS patients had a higher crude in-hospital case-fatality ratio (NRS 41.1 % vs. RS 32.0 %), but a lower risk of death after adjusting for confounders (HR 0.88 [0.83-0.93]). Conclusion: Approximately one in seven COVID-19 patients presented at hospital admission without respiratory symptoms. These patients were older, had lower ICU admission rates, and had a lower risk of in-hospital mortality after adjusting for confounders
