Authors: Chennamasetti Kaumudi , Muley Arti 
Published: March 2020

Background: Both SCD and Vit. D deficiency may cause joint pain. So, Vit. D may have a contributory role in severity of SCD presentation. This study was performed to assess burden of Vitamin D levels and association of vitamin D deficiency with severity of SCD in a tertiary care centre in India.Methods: This was a cross-sectional study, performed for one and half year. All SCD patients >18 years of age were included. Data was analysed to assess the burden of Vitamin D deficiency and to find out any correlation of S. vitamin D level with anemia, jaundice and number of episodes of hospital admissions in patients of SCD.Results: Total 50 patients were included. Multiple joint pain and easy fatigability were the most common symptoms. Most of them had history of jaundice and anaemia in the past, 84% had Vitamin D deficiency. There was significant difference in values of serum total bilirubin, blood urea, SGPT, SGOT, HbF, HbA2 and haemoglobin between the patients with Vitamin D3<30 and vitamin D3≥30 (p<0.05). There was a significant positive correlation of vitamin D3 with haemoglobin (r = 0.889) and a negative correlation with Hb A2 (r= -0.123) and total bilirubin (r= -0.438).Conclusions: Vitamin D3 deficiency is associated with increased morbidity in SCD in terms of joint pain, anemia and jaundice. Routine testing and supplementation of Vitamin D levels in these patients may help to alleviate pain, improve functionality and reduce complications.

About the Cover The Burning of the Houses of Lords and Commons, 16 October 1834, 1835 Joseph Mallord William Turner (British, 1775-1851) oil on canvas, Framed: 123.5 x 153.5 x 12 cm (48 9/16 x 60 3/8 x 4 11/16 in.); Unframed: 92 x 123.2 cm (36 3/16 x 48 1/2 in.). Bequest of John L. Severance 1942.647 Image Credit: Cleveland Museum of Art On the night of October 16, 1834, fire consumed the Houses of Parliament in London. Londoners gathered along the banks of the river Thames to gaze in awe at the horrifying spectacle. Initially, a low tide made it difficult to pump water to fire-fighting equipment on land; likewise, it hampered steamers towing fire-fighting equipment up the river. Although the tides eventually shifted, the effort was futile, as the fire burned uncontrollably for hours. Turner records this as the steamers in the lower-right corner head toward the flames.Although Turner based the painting on an actual event, he used the disaster as the starting point to express man’s helplessness when confronted with the destructive powers of nature, here dissolved in brilliant swaths of color and variable atmospheric effects that border on abstraction.

Published: March 2020

<p>Following the release of Presidential Regulation No 1/2016, a peat restoration pilot project has been carried out in Banjarbaru District, South Kalimantan in addition to other two pilot projects in other provinces of Indonesia. The pilot project has been designed to implement the three aspects of peat restoration, namely rewetting, revegetation and revitalization of society. Implementation of revegetation is mainly through applying agroforestry by growing agricultural crops in spaces between trees. The objective of present study was to elucidate the suitability of agricultural crops in area of restoration of degraded peatland in South Kalimantan, Indonesia. The suitability of agricultural crops was studied by collecting rainfall and air temperature data from the climatic station of Syamsudin Noor Airport in Banjarbaru, while the nutrient retentions values were determined in the laboratory. Peat depth and drainage class were determined by direct field observations, while peat decomposition level was classified by quantitative method in the field. All collected data were then used to assess the land suitability class for dry land paddy (<em><span style="text-decoration: underline;">Oriza</span> <span style="text-decoration: underline;">sativa</span></em> L), long bean (<em><span style="text-decoration: underline;">Vigna</span> <span style="text-decoration: underline;">sinensis</span></em> ENDL), cucumber (<em><span style="text-decoration: underline;">Cucumis</span> <span style="text-decoration: underline;">sativus</span></em> LINN), mustard (<em><span style="text-decoration: underline;">Brassica</span> <span style="text-decoration: underline;">rugose</span></em> FRAIN), orange (<em><span style="text-decoration: underline;">Citrus</span></em> sp), <em>stink bean</em> (<em><span style="text-decoration: underline;">Parkia</span> <span style="text-decoration: underline;">speciose</span></em> HASSK), rubber (<em><span style="text-decoration: underline;">Hevea</span> <span style="text-decoration: underline;">brassialiansis</span></em> M.A), and coconut (<em><span style="text-decoration: underline;">Cocus</span> <span style="text-decoration: underline;">nocifera</span></em> L). The productivity data of long bean, cucumber and mustard were obtained by farmer interview. The results showed that most of the agricultural crops were classified as marginally suitable (Class S3).The main limiting factors of agricultural development in this area are low soil pH, low base saturation and peat ripening. Peat depth limits the development of some crops. The above mentioned limiting factors ought to contribute to the low crop productivities in the area. The limiting factors were less severe for pineapple and stink bean, indicating that these crops have potential to be grown along with trees for restoration efforts in the area.</p>

Published: March 2020

The existence of the Musi River is very important not only for the population of South Sumatra, but also for the Bengkulu and Lampung regions. The main problem is the high rate of sedimentation, and the alleged increase in heavy metal content. The research aims were to determine the sedimentation rate and metal content in river mud in dry season. Samples of water, mud, and sediments were taken in the waters of Musi Hilir in the area around Kemarau Island in August-September 2018. The results of laboratory analysis showed that the river had been moderately polluted, where the ammonia content in the water was above the quality standard, and the Fe content in the mud is classified as high (above the quality standard). The sediment accumulation in the nine samples at three stations showed at Station 1 was 0.022429739 g cm<sup>-1</sup> day<sup>-1</sup>. The highest accumulation rate of sediment weight was found at Station 2 which was 0.038456224 g cm<sup>-1</sup> day<sup>-1</sup>. The lowest sediment accumulation rate was found at Station 3, which was only 0.007109631 g cm<sup>-1</sup> day<sup>-1</sup>. The cause of the low accumulation of sediment at Station 3 was due to flow velocity at this location tends to be large, so that the sediment was difficult to settle. If the assumption was four months dry season, the accumulation of sediment was estimated at 26.9 tons / m<sup>2</sup> / 4 months.

Published: March 2020

Increasing rice consumption demand in Indonesia has provided serious problems such as food insecurity. Being the major staple food, rice production is the main priority of medium and long term development planning in Indonesia. Local rice production is strongly affected by climate conditions, especially in South Kalimantan. Nowadays, the world must adjust to climate change. One of significant effects of changing climate on agriculture is related to productivity. Evapotranspiration is the major cause of loss of water needed, for agricultural requirements. The crop requires effective irrigation system with adequate water amount. The main objective of this research is to analyze the water requirements for the irrigation units in Barito Kuala, South Kalimantan concerning local rice cultivation under the climate change scenarios. Supposed rainfall during the 2050s and 2090s are obtained from four downscaled circulated models and one model for projected temperature under CMIP5 with RCPs 8.5 scenario. Penman-Monteith method was used to calculate the evapotranspiration value. Based on future effective rainfall water requirement is estimated. The result shows the impact of climate change on the water irrigation requirement of local paddy cultivation are 56% and 25 % higher than current condition in July and September October respectively.

Terlebih Sayyidah Aisyah yang dinobatkan sebagai perawi terbanyak di kalangan perempuan, tentu saja mempunyai peran yang lebih dibanding istri-istri Nabi yang lain. Hal ini dipengaruhi oleh fator internal, yaitu secara pribadi beliau memang mempunyai keunggulan terkait daya intelektualitasnya; dan faktor eksternal yaitu beliau adalah istri Nabi yang paling dicintai oleh Nabi sehingga intensitas kebersamaannya dengan Nabi paling tinggi dibanding istr-istri yang lain, oleh karenanya peluang beliau untuk mengakses dan merekam sunah-sunah Nabi baik yang berupa perkataan, haliyah perbuatan, dan taqrir Nabi dalam berbagai hal tentu saja lebih banyak.</span></p><p class="06IsiAbstrak"><span lang="EN-GB">Lembaran sejarah Islam menginformasikan bahwa pada masa permulaan Islam, banyak wanita muslimah yang ilmunya banyak dimanfaatkan oleh kaum muslimin.
