Hermetic Bag: A Farmers Friendly Paddy Storage Technology in Bangladesh

In Bangladesh, most of the farm households store paddy to meet their own consumption, facing emergency needs and seeds for the next sowing season in traditional storage technologies which susceptible to insect, rodent and mold. Training and Focus Group Discussion (FGD) were conducted to disseminate hermetic (PICS and GrainPro) bag at Mymensingh and Jashore regions. The participants learned the use of moisture meter in paddy drying and safe storage. Pedagogical approach was followed in the FGD among 100 farmers of different age with their spouse. Farmers’ perception about these bags was also taken. Traditional storage technologies namely, Dole, Motka, Guny Bag, Bamboo Gola, Dhari, Bamboo Auri, and Berh were identified which are not durable or functional in Bangladesh. Among these, Dole and Plastic Bag for consumption, and Motka and Plastic Drum were found suitable for paddy seed storage. Women taught to neighbors about the operation of moisture meter and HB. About 87, 13% farmers prefer 10-20 and 40-50 kg size HB in Mymensingh while 82 and 18% farmers of Jashore prefer corresponding sizes of bags for seed purposes. For sale and consumption purposes, about 40, 35 and 20% farmer preferred 500, 1000 and 2000 kg size HB in Mymensingh. On the contrary, about 26, 38 and 36% farmers prefer same size of HB in Jashore. Farmer shown keen interest about HB and concerned of its high price. They opined price of 40-50 and 500-2000 kg size HB should be within Tk. 20 and Tk. 200, respectively. Both female and male farmers can store paddy in it properly. Price of hermetic bag is high, ranked as no. 1 problem followed by its availability in different sizes locally. However, HB was found effective in paddy storage in Bangladesh.

Research on British and American literature resources system based on cloud storage

The rapid growth of data in the information age limits traditional storage technologies and the ability to manage data, and cloud storage systems emerge as the times require. Cloud storage is a new business application model that integrates a large number of resources in a distributed form and provides integrated services to users. Cloud computing, which relies on thousands of cheap computers, has dramatically reduced server costs. Cloud storage technology can effectively solve the problems of high storage cost, low sharing rate and irregular management of educational resources. In order to meet the needs of English education in the information age, this paper studies the English and American literature resource system based on cloud storage, and completes the system architecture design, data structure design and upload module design, which is convenient for software developers to build the system.

A Review of DNA Data Storage Technologies Based on Biomolecules

: In the information age, data storage technology has become the key to improving computer systems. Since traditional storage technologies cannot meet the demand for massive storage, new DNA storage technology based on biomolecules attracts much attention. DNA storage refers to the technology that uses artificially synthesized deoxynucleotide chains to store and read all information, such as documents, pictures, and audio. First, data are encoded into binary number strings. Then, the four types of base, A(Adenine), T(Thymine), C(Cytosine), and G(Guanine), are used to encode the corresponding binary numbers so that the data can be used to construct the target DNA molecules in the form of deoxynucleotide chains. Subsequently, the corresponding DNA molecules are artificially synthesized, enabling the data to be stored within them. Compared with traditional storage systems, DNA storage has major advantages, such as high storage density, long duration, as well as low hardware cost, high access parallelism, and strong scalability, which satisfies the demands for big data storage. This manuscript first reviews the origin and development of DNA storage technology, then the storage principles, contents, and methods are introduced. Finally, the development of DNA storage technology is analyzed. From the initial research to the cutting edge of this field and beyond, the advantages, disadvantages, and practical applications of DNA storage technology require continuous exploration.

An adaptation-complete proof system for local reasoning about cloud storage systems

• A new Hoare-style proof system to analyze and verify cloud storage system management programs. • A formalization of modular local reasoning about program correctness verification. • A set of adaptation rules to adapt the condition of specifications to broader contexts. • The soundness and adaptation completeness of the proof system. The rapid growth of data presents a significant challenge to the capability of traditional storage technologies to collect and manage data. Cloud storage systems (CSSs) have been proposed as a method to improve storage capacity. To safely and effectively manage cloud storage data and improve data service quality, it is necessary to verify the correctness of CSS management programs. However, the complexity of these systems renders program verification difficult. In this paper, we propose a Hoare-style proof system, in conjunction with two languages, to analyze and verify CSS management programs. The first is a modeling language that describes the program execution. The second is an assertion language based on Separation Logic (SL), used to describe the properties of the CSS file-block-location storage structure. The proof system supports modular local reasoning for CSS programs by a set of adaptation rules, which enable the condition of specifications to be applied to broader contexts. A key question that arises is whether the proof system can meet adaptation completeness. If so, arbitrary satisfiable specifications can be adjusted using the adaptation rules. To this end, we developed local predicate transformers and used their domain to interpret all types of commands. By finding the smallest local predicate transformer, we established adaptation completeness. In summary, this work provides a formalization of automatic modular reasoning patterns and lays a theoretical foundation for the compositional program verification of CSSs.

PRESENT STATUS OF AGRICULTURAL MECHANIZATION: A STUDY ON THREE UPAZILAS OF PANCHAGARH DISTRICT IN BANGLADESH

Nowadays in Bangladesh, farm mechanization is one of the major cause of change in agricultural sector. Due to labor shortage and high wage rate of labor, farmers are compelled to accept farm mechanization. The purpose of the study was to assess the modern agricultural technologies used in Panchagarh district and develop statistical information. The study period was from August 2019 to October 2019. For this study, three places such as Panchagarh Sadar, Boda and Debiganj were selected. Present status was analyzed based on irrigation management system, tillage practices, insect control practices, harvesting and post-harvesting operation, drying and storage facilities for rice production. A structured questionnaire was used to collect the information’s of machinery used in selected places. The study revealed that irrigation, land preparation and crop protection was almost mechanized, but mechanization is still lacking in harvesting operation. There were no transplanter, seed drill and fertilizer applicator found in the study areas used by farmers. Crops were still dried through sun drying storage was done by the traditional storage technologies. It is a fact that mechanization is in progress in these areas but need more extension work with modern machineries. The government should develop proper planning by investigating present status of mechanization and improve the present condition by increasing machinery utilization.

Performance optimization method for distributed storage system based on hybrid storage device

In the era of big data and artificial intelligence, the storage data of data centers is growing rapidly. Big data storage systems with high-performance computing require high-speed data access and greater storage capacity. However, traditional storage technology based on hard disk media (HDDs) has been difficult to meet the current demand for high-performance storage, solid state drives (SSDs)’ cost will be a lot for storing massive amounts of data. Therefore, in response to the above problems, this paper proposes a hierarchical hybrid storage technology for distributed file system, including an adaptive file migration strategy and client caching mechanism. Through experimental verification, the proposed technology fully combines the high I/O throughput characteristics of SSDs and the large capacity characteristics of disks, thereby providing a cost-effective high-performance distributed storage solution, and when processing real-time data, it has higher access performance.

Novel Co‐Doped Y2GeO5:Pr3+,Tb3+: Deep Trap Level Formation and Analog Binary Optical Storage with Submicron Information Points

AbstractOptical information storage (OIS) is considered as one of the most promising data storage methods due to unique advantages of high security, long life, and low‐energy consumption. Combination of optically stimulated luminescence of electron‐trapping materials (ETMs) and advanced optical technology has been proved to be a feasible approach to break through physical limitations of traditional storage technology. However, inorganic ETMs are limited to laboratory research, and have not realized the submicron recording point of “microscopic” analog optical storage so far. In this work, an exemplary application of OIS employing inorganic ETMs by a custom‐built optical system has been realized for the first time. Multidimensional triple traps are tailored through co‐doping of selective rare‐earth ions Tb3+ into Pr3+‐activated Y2GeO5. Furthermore, first principles calculations, combined with X‐ray photoelectron spectroscopy and low‐temperature electron spin resonance spectra, reveal the nature of trap levels. Remarkably, a {10 × 10} array of information points is automatically recorded in a bit‐by‐bit mode by a 515 nm femtosecond laser, then decoded by linear continuous scanning, and the emission spectrum between each two information points is detected to realize “0” and “1” in binary information. Hopefully, the present work can push forward practical application of inorganic ETMs in high‐density and super‐speed OIS.

Quality of milled rice in different storage technologies

Quality of milled rice deteriorates if it is not stored properly. Storage conditions alter the physicochemical properties of rice. The main objective of the study was to find out the sensual differences among different storage technologies and determine the consumer level of acceptance. Moisture content of stored milled rice was monitored during nine months of storage in different storage structures. The sensory quality of stored milled rice in three traditional storage technologies (Kolshi, steel drum and plastic drum) and hermetic bag like GrainPro bag for two rice varieties (Tulshimala and BRRI dhan49) was analysed for consumer's acceptability using panel test of 20 non-trained judges. The overall acceptance of cooked sample was determined based on the evaluation of the rice aroma, appearance, taste, and stickiness. Based on the taste, appearance, aroma and stickiness of cooked milled rice, GrainPro bag was found satisfactory in comparison to traditional storage technologies.

Environmental Aspects of Using Metal Organic Frameworks as Adsorbents in Natural Gas Storage Systems

This work is in direct support of GM’s ongoing effort in developing transformational technologies to reduce the barriers of onboard Natural Gas mass adoption. Alternative NG storage technologies seek to bypass the pressure and thermal challenges of traditional storage technologies by utilizing the chemical and physical properties of certain solid materials to store gas. While the gas adsorption/desorption properties, thermodynamics and kinetics of the adsorbent materials have been evaluated in depth there is, to our knowledge, no report of the compatibility of the same materials with the pressure vessel liner at (P, T) operating conditions. The stability of the benchmark Metal Organic Framework, Cu3BTC2, in the presence of Natural Gas contaminants and its impact on the metallic tank liner material has been investigated and will be addressed in this report.

DCache, Sync-and-Share for Big Data

The availability of cheap, easy-to-use sync-and-share cloud services has split the scientific storage world into the traditional big data management systems and the very attractive sync-and-share services. With the former, the location of data is well understood while the latter is mostly operated in the Cloud, resulting in a rather complex legal situation.Beside legal issues, those two worlds have little overlap in user authentication and access protocols. While traditional storage technologies, popular in HEP, are based on X.509, cloud services and sync-and-share software technologies are generally based on username/password authentication or mechanisms like SAML or Open ID Connect. Similarly, data access models offered by both are somewhat different, with sync-and-share services often using proprietary protocols.As both approaches are very attractive, dCache.org developed a hybrid system, providing the best of both worlds. To avoid reinventing the wheel, dCache.org decided to embed another Open Source project: OwnCloud. This offers the required modern access capabilities but does not support the managed data functionality needed for large capacity data storage.With this hybrid system, scientists can share files and synchronize their data with laptops or mobile devices as easy as with any other cloud storage service. On top of this, the same data can be accessed via established mechanisms, like GridFTP to serve the Globus Transfer Service or the WLCG FTS3 tool, or the data can be made available to worker nodes or HPC applications via a mounted filesystem. As dCache provides a flexible authentication module, the same user can access its storage via different authentication mechanisms; e.g., X.509 and SAML. Additionally, users can specify the desired quality of service or trigger media transitions as necessary, thus tuning data access latency to the planned access profile. Such features are a natural consequence of using dCache.We will describe the design of the hybrid dCache/OwnCloud system, report on several months of operations experience running it at DESY, and elucidate the future road-map.
