Date palm (Phoenix dactylifera) is an important fruit and cash crop in Sultanate of Oman, occupying nearly 60% of the total cultivated area. However, leaf spots caused by Mycosphaerella tassiana, Alternaria spp., and Dreshcleri sp. have become a threat to date palm's cultivation in recent years. In this study, a field experiment was conducted to find out a suitable chemical spray program to control the disease. A prophylactic spray schedule with mancozeb (Dithane M45), copper oxychloride (Champion), and mancozeb+copper (Trimiltox) effectively controlled the disease when applied at a time when the disease severity index (DSI) was low, ranging from 0 to 1.68. Meanwhile, the disease did not decrease, but instead increased gradually, when the fungicide combination was applied when DSI was high, ranging from 1.78 to 5.37. It was concluded that fungicides should be applied at the early stage or before disease initiation in order to control the disease effectively.

This research explores the fall of pre-independence Sultanates and its continued political, economic, and cultural influence in post-colonial Indonesia. By using qualitative and historical methods, this paper compares the Sultanates of Mataram in Yogyakarta and Al-Kadrie in Pontianak, which represent different historical paths supporting the struggle for independence during the mid-20th century. Sultan Hamid II of the Al-Kadrie was a supporter of federalism whereas Sultan Hamengkubowono IX of Yogyakarta was an advocate of the republican system. Eventually, Indonesia became a Republic, and the idea of federalism was sidelined, which led to the abolition of sultanates in the rise of the = Indonesian nation-state, except for the Sultanate of Yogyakarta. After the 1998 Reform, the current development of democracy created political opportunities for the Al-Kadrie to reclaim its authority through engagement with various civic organizations. Meanwhile, the Sultanate of Yogyakarta faces internal friction because of succession concerns.

The paper examines, in the light of current historiography, the recent trends in the application and applicability of the World Historical studies on the Indian Ocean scenario. Calling for the combination of the breadth of the World Historical studies with the analysis of a historical scenario in its specific spatio-temporal context-instead of a synchronic approach-the present study takes a close look at commerce and politics in the western Indian Ocean in the light of an early 14th century Latin Crusade tract, How to Defeat the Saracens by William of Adam (Guillelmus Ade, Tractatus quomodo Sarraceni sunt expugnandi), a Dominican friar. The text offers remarkable insights into the interlocking of the Indian Ocean and the South Asian subcontinent with the Mamluk Sultanate, the Ilkhanid realm and the Crusades. The paper argues for what is now termed as braided and connected histories.

This study investigated the use of multinutrient blocks (MNB) composed of 35% date syrup, 35% date syrup byproducts, 10% date fronds, 7% urea, 7% cement and 6% common salt for growing small ruminants, as partial substitute for the roughage component of the diet (Rhodes grass hay) and its effect on feedlot performance and economics of feeding. Eight growing local Omani goats and 8 sheep (each about one year old) were used in this study. Mean body weights for goats and sheep (kg), respectively were $21.1{\pm}4.5$ and $25.5{\pm}4.1$. The goats and sheep were subdivided into two sub-groups of more or less equal body weights for each species. Each sub-group in both species was either fed on 0.5 kg concentrate+ad libitum Rhodes grass hay or the same diet+restricted hay (about 0.2 kg/head/day) and ad libitum amount of MNB. Sheep significantly (p<0.05) consumed greater amounts of MNB ($36{\pm}17$g/head/day) than goats ($6{\pm}2.5$ g/head/day). Feeding of the MNB was effective in sparing about 40% of the roughage Rhodes grass hay for goats (from 240 to 140 g) and about 42% for sheep (from 252 to 146 g) or approximately 100 g/head/day for both goats and sheep. This reduction (or sparing) in the consumption of Rhodes grass hay was coupled by an improvement in daily liveweight gain (g/head/day) in both goats (from 29 to 46 by 58.6%) and sheep (from 26 to 39 by 50%) and also by an improvement in the feed conversion efficiency (g feed/g gain) of both goats (from 25 to 13.8 by 45%) and sheep (from 28.7 to 17.2 by 40%). Cost of daily consumed feeds as well as cost/kg gain (or cost of meat) were both reduced due to feeding of MNB. They were both respectively reduced by 7.5% (from 53 Baisa/day to 49) and 38% (from 1,828 Baisa/kg to 1,140). It was economically viable to feed MNBs containing date by-products and urea to small ruminants in the Sultanate of Oman.

Omani citizens participate in building the culture of democracy through the implementation of the legal deposit or the Law of Printing and Publishing. Legal deposit is the law that requires individuals and agencies who are responsible for printing and applying the law in Oman, whether they are publishers, printing houses or authors, to submit certain copies of their work or publications to a repository, usually a library. The present study aims to explore the reality of the Omani Law of Printing and Publishing and discover how the law defines the term "publications". In addition to the role of this law in building the Omani culture of democracy, the study uses an interpretive research paradigm of applied unstructured interviews and content analysis. Twenty-four printing houses were interviewed. The findings determined that definition of the term "publications", according to the law, is very general and covers different items, and the Law of Printing and Publishing plays an essential role in the building of Oman's culture of democracy. The study also found that all of the printing houses interviewed participated in creating the Omani culture by depositing the requested copies of their publications, although four of them had negative beliefs about the law of "Printing and Publishing". In addition, the study found (19=79.1%) of the sample interpreted the term "culture of democracy" in a positive way.

Investment authorities are broad financial institutions that carefully manage investments on behalf of the national government using a long-term value development approach. To provide a stronger structure or framework for In-vestment Authorities to govern the distribution of funds to public and private markets, we've started research to create a blockchain-based prototype for managing and tracking numerous finances of such authorities. We have taken the case study of Oman Investment Authority (OIA) of Sultanate of Oman. Oman's wealth is held in OIA. It is an organization that oversees and utilizes the additional capital generated by oil and gas profits in public and private markets. Unlike other Omani funds, this one focus primarily on assets outside the Sultanate. The operation of the OIA entails a huge number of transactions, necessitating a high level of transparency and administration among the parties involved. Currently, OIA relies on various manuals to achieve its goals, such as the Authorities and Responsibilities manual, the In-vestment Manual, and the Code of Business Conduct, among others. In this paper, we propose a Blockchain based framework to manage the operations of OIA. Blockchain is a part of the Fourth Industrial Revolution, and it is re-shaping every industry. The main components of every blockchain are assets and participants. The funds are the major assets in the proposed study, and the participants are the various fund shareholders/recipients. The block-chain's transactions are all safe, secure, and immutable, and it's part of a trustless network. The transactions are simple to follow and verify. By replacing intermediary firms with smart contracts, blockchain-based solutions eliminate any middlemen in the fund allocation process.

Four field experiments were carried out from 1998 to 1999 and from 1999 to 2000 growing seasons of potato to investigate the relationship between leafminers and Alternaria alternata. The experiments established differential susceptibility among potato varieties to alternaria leaf necrosis, relationship between leafminer infestation and the level of necrosis, use of insecticides to reduce leafminer and leaf necrosis damages, and use of polyester fleece to eliminate leafminer and eventually reduce leaf necrosis. Results of the study indicate that control of leafminer is of primary importance because this will automatically lead to control of the damage caused by A. alternata.

One of the most important problems in the estimation of the parameter of the failure model, is the cost of experimental sampling units, which can be reduced by using any prior information available about ${\theta}$, and devising a two-stage pooling shrunken estimation procedure. We have proposed an estimator of the reliability function (R(t)) of the exponential model using two-stage time censored data when a prior value about the unknown parameter (${\theta}$) is available from the past. To compare the performance of the proposed estimator with the classical estimator, computer intensive calculations for bias, mean squared error, relative efficiency, expected sample size and percentage of the overall sample size saved expressions, were done for varying the constants involved in the proposed estimator (${\tilde{R}}$(t)).

It is conventionally accepted that renal cell carcinoma (RCC) occurs in older patients and the clear cell type is the most common histology. However, ethnic variations exist and this study was carried out to determine the epidemiological pattern of RCC in Oman. Ninety RCC patients who presented to a tertiary care center in the Sultanate of Oman from 2010 to 2014 were studied. The main findings were that the median age of presentation was low, more patients presented with localized stage, and there was a higher incidence of non-clear (especially papillary) histology. Data from other Gulf countries and possible reasons for the different profile are discussed.
