  The study was carried out to assess the input use pattern, comparative profitability and resource utilization to cabbage cultivation in different growing periods. The highest gross return as well as net return was obtained from pre-rabi period of cabbage cultivation. The lowest gross return and net loss was obtained from late-rabi period of cabbage cultivation. The study revealed that cabbage cultivation is more profitable in pre-rabi period and least profitable (actually negative profitable) in the late-rabi period. The benefit cost ratio was the highest for pre-rabi period in both variable cost and total cost basis. Return to labour was calculated highest for pre-rabi cultivation indicating best use of highest cost involvement input. Marginal rate of return was found 1667% for pre-rabi cultivation which implies that taka one hundred additional investment to pre-rabi rather than optimum-rabi will provide additional taka 1667 to the growers.

  This study proposes a new method for computing f(U) where f is a real continuous function and U is a fuzzy interval. The computation of f(U) is performed by incorporating optimisation technique into Zadeh’s extension principle. By discretising α up to n finite numbers, a set of n closed and bounded intervals is obtained. Here, the computation of f on closed and bounded intervals is the same idea of solving unconstrained optimisation problems. For every finite numbers of α, if the function to be optimised is unimodal, the authors apply Brent’s method. One of the main advantages of using this method is that it does not require the calculation of derivative. In case where f is reduced to monotone or to a straight line, the optimal solutions are obtained at the endpoints of intervals. This new strategy gives better results and requires only few function evaluations. An example is provided to illustrate the effectiveness of the proposed method.

  This study proposes a hybrid method called Particle Swarm Optimization-Fuzzy Euler Method (PSOFEM) for solving fuzzy differential equations. The PSOFEM is obtained by embedding a particle swarm optimization technique in a fuzzy Euler scheme. Results of applying the PSOFEM to several fuzzy differential equations are presented. Final results showed that the PSOFEM is capable of generating fuzzy solutions for a large class of problems.

  Nowadays, the technology utilization and adoption considered as one of the trend researches in different contexts. In order to achieve successful utilization, a number of factors may be taken into consideration from different perspectives depending on the real needs in the context of usage. Healthcare context still needing the utilization of new trend technologies such as utilizing cloud computing services to handle different tasks in this domain. The cloud services can offer a reliable solution to manage, maintain and retrieve health records within hospitals as well as to share the activities among hospitals and healthcare specialists. This allows the healthcare professionals to access, manage and monitor patient’s health status anywhere at anytime. In order to make sure to get the full benefits of the new services, a prior examination in the context of usage must be applied to examine the current needs and the suitability of the technology. Therefore, the researchers in the present study trying to provide the suitable factors/domains used in the context of technology utilization in healthcare sector. A literature survey has carried out to check the suitability of the organizational structure and system settings and their impact on the healthcare member’s perception to utilize cloud health information systems. A total of 75 previous studies that used the proposed domains in different contexts has been included. Along with that, the researchers found that the studies in the context of technology utilization usually used three theories to combine the relationship between the above-mentioned domains. These theories are the organization theory, diffusion of innovation theory and the theory of reasoned action. Finally, the association between domains and the theories have been established.

  It is commonly perceived that the value of healthcare services constantly increases in developing and developed countries to which healthcare providers are currently becoming more challenging. Consequently, taking on advanced health information systems to reduce healthcare cost and improve overall health quality is imminent in countries that are still in service utilization stage like Iraq. This as a result, led researchers to consider the potential of cloud computing as a prominent technological solution for providing the necessary platform for health information technology services to be transformed and managed over the internet. This allows the healthcare professionals to access, manage and retrieve patient’s health records in a reliable and flexible way. However, cloud computing has also introduced a set of challenges in healthcare contexts which varied from one country to another depending on its current technological state and resources. The researchers shed light on these challenges in the present study by surveying the literature about the current antecedents that may face the Iraqi health sector to utilize cloud health information systems. The literature showed that using other models is not recommended as it implies different needs that make it difficult to fit certain cultural or geographical conditions as it in Iraq. As a result, this research proposed a model of utilizing cloud health information systems in Iraq. The organizational structure and system factors have been investigated as the main antecedents that may affect the perception of the healthcare professionals (individuals) towards utilizing cloud services in their hospitals.

  The effect of plant spacing and different sources of nutrient was studied on the growth and yield of cabbage. The experiment was conducted with two plant spacings (60cm x 45 cm, 60cm x 60 cm) and four levels of nutrients (no fertilizer, organic manures, organic + inorganic fertilizers and inorganic fertilizers) in RCB design. Plant spacing had marked influence on the growth parameters like number of loose leaves per plant and diameter of head. The plant under closer spacing produced high marketable yield (64.38t ha -1) than wider spacing. Plants those received organic + inorganic fertilizers produced the highest marketable yield (79.01 t ha -1). The treatment combination of 60 cm x 45 cm spacing with organic + inorganic fertilizers gave the highest marketable yield (86.68 t ha -1) of cabbage.

  The field experiment was carried out to find a suitable and economic dose of fertilizer (combination of N, P2O5, K2O and S) for potato cultivation in no tillage mulching situation. Three fertilizer packages with a control (without fertilizer) were tested. At all locations, the treatment F4 (120, 100, 120 and 20kg ha–1 N, P2O5, K2O and S respectively, out yielded the control as well as other fertilizer doses. The tuber yield pattern due to different fertilizer packages followed the same trend for all tested locations but overall performance of Shariatpur was better than Madaripur and Gopalgong. The gross return, gross margin and marginal rate of return were also found the highest in same treatment at all the three locations.

  The experiment was undertaken to determine the effect of spacing on onion cultivation of different varieties. Different spacings were taken 20x10 cm, 15x10 cm, 10x10 cm, 15x7.5 cm, 10x7.5 cm and 7.5x7.5 cm. Three varieties viz BARI Piaz-1, Taherpuri and Faridpur Bhati were used for study. Significantly wider spacing produced higher size of plant height, leaf length and number of leaves. Bulb length, diameter and weight also the same trend in wider spacing. The weight of individual bulb of onion (23.52 g) was increased with the widest spacing (20x10 cm). On the contrary, yield ha–1 was the highest (16.65 t ha–1) at the closest spacing (7.5x7.5 cm) and the lowest (10.05 t ha–1) was at widest spacing (20x10 cm). But in closer spacing, bulb size was so small that was not suitable for the choice of consumer. On the other hand wider spacing produced the highest percentage (24.34%) multiplier bulbs that was not better for storing and consumers demand. So, in respect of economic point of view 15x10 cm spacing recommended in onion cultivation. It was found BARI Piaz-1 performed better in respect of yield and other parameters.
