Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Preface
This Nepal Standard was prepared during 1993 as part of a project to prepare a draft National Building
Code for Nepal.
In 1988 the Ministry of Housing and Physical Planning (MHPP), conscious of the growing needs of
Nepal's urban and shelter sectors, requested technical assistance from the United Nations Development
Programme and their executing agency, United Nations Centre for Human Settlements (UNCHS).
A programme of Policy and Technical Support was set up within the Ministry (UNDP Project
NEP/88/054) and a number of activities have been undertaken within this framework.
The 1988 earthquake in Nepal, and the resulting deaths and damage to both housing and schools, again
drew attention to the need for changes and improvement in current building construction and design
methods.
Until now, Nepal has not had any regulations or documents of its own setting out either requirements
or good practice for achieving satisfactory strength in buildings.
In late 1991 the MHPP and UNCHS requested proposals for the development of such regulations and
documents from international organisations in response to terms of reference prepared by a panel of
experts.
this document has been prepared by the subcontractor's team working within the Department of
Building, the team including members of the Department and the MHPP. As part of the proposed
management and implementation strategy, it has been prepared so as to conform with the general
presentation requirements of the Nepal Bureau of Standards and Metrology.
The subproject has been undertaken under the aegis of an Advisory Panel to the MHPP.
The Advisory Panel consisted of :
Mr. UB Malla, Joint Secretary, MHPP Chairman
Director General, Department of Building
(Mr. LR Upadhyay) Member
Mr. AR Pant, Under Secretary, MHPP Member
Director General, Department of Mines & Geology
(Mr. PL Shrestha) Member
Director General, Nepal Bureau of Standards & Metrology
(Mr. PB Manandhar) Member
Dean, Institute of Engineering, Tribhuvan University
(Dr. SB Mathe) Member
Project Chief, Earthquake Areas Rehabilitation &
Reconstruction Project Member
President, Nepal Engineers Association Member
Law Officer, MHPP (Mr. RB Dange) Member
Representative, Society of Consulting Architectural &
Engineering Firms (SCAEF) Member

0 Foreword
This Nepal Standard comprises the Indian Code IS 456-1978 Code of Practice for Plain and
Rainforced Concrete (Third Revision) amended so as to meet the conditions of Nepal. In
particular, these amendments have been necessary to ensure compatibility with the Nepal
Standard NBC 105-94 : Seismic Design of Buildings in Nepal.
This document contains the amendments that are to be made to IS 456-1978 for its use in
Nepal.
Most of the references is IS 456-1978 to Indian material Codes have been left unaltered until
such time as appropriate Nepal Standards are developed.
Any subsequent revisions to IS 456-1978 shall be not be applicable to this Nepal Standard NBC
110-94 until specifically recognised by this Standard.

1.3 In this Standard, the word "shall" indicates a requirement that must be adopted in
order to comply with the Nepal Standard and the word "should" indicates
recommended practice.
3.1 Add
3.1 SL: Snow load
Section 2 – Materials, Workmanship, Inspection and Testing
4.1.a Replace "IS: 269-1976" with "NS 49-2041".
4.2.2 Replace "code" with "Standard".

2 For the serviceability limit state, the values γ f given in this table are applicable for short
term effects. While assessing the long term effects due to creep, the dead load and only
that part of the live load likely to be permanent may be considered.
*
This value is to be considered when stability against overturning or stress reversal is critical
