Story & Experience / An Outstanding Study Tour with...
Last post by aliarawshan - Jun 13, 2023, 05:16 AMAn Outstanding Study Tour with DIC students
On 27 May 2023, the students of class XI (session: 2022-23) along with their teachers started for Bangabandhu Military Museum at 9.30 am. The museum is located at Bijoy Sarani, Dhaka. It has a collection of Bangladesh's military history, heritage, success stories and various weapons and ammunition.
As the destination is not very far from college campus, we have decided to go on foot. While crossing Manik Mia Avenue, the juvenile students had some snaps in front of the Parliamentary Building. They were, really, excited and thrilled while marching towards the destination. We reached the museum at 10.30 am and found that some of my fellow students had already arrived at their most cherished destination.
After finishing the counting of the students, they entered the museum in a queue maintaining discipline and rules of the institution. While exploring the museum, they observed our heritage, success stories of our ancestors, wide implementation of Augmented Reality, Interactive Displays, Virtual Reality, Holograms etc.
The museum is divided into six sections, including the Bangladesh History Gallery on the ground floor, Bangladesh Army Gallery on the 2nd floor, Bangladesh Air Force gallery on the 3rd floor, UN Peacekeeping Gallery on the 4th floor, and Bangladesh Navy Gallery at the basement.
There is also a separate museum named "Toshakhana Jadughor" within the museum complex, where gifts and awards received by the country's important personnel have been showcased. A grand sculpture of Bangabandhu Sheikh Mujibur Rahman has been placed in the middle of the "Toshakhana Jadughor".
Our students got amazed looking at the awesome architectural design and infrastructure inside the museum. The study tour came to an end almost at 1.00 pm. At the end of the tour, they experienced a heavy rainfall poured down the city which made the day more memorable for them. Due to excessive rainfall, we had to wait some more time at the museum. This study tour and the rainfall made the students refreshed by removing the monotony of academics.
Overall, it was an unforgettable outing of the teachers and the students which will remain forever in the memory and keep us invigorated again and again.
Finally, I would like to say that this kind of study tour offers unique opportunities for students to learn, grow, and develop both academically and personally. Moreover, it provides practical experiences through gaining knowledge and foster various skills that are essential to achieve success in the academic and professional spheres.

Advice to Students / আমের পুষ্টি ও ভেষজগুণ
Last post by nelufayesmen - May 17, 2023, 05:29 AMআমের পুষ্টি ও ভেষজগুণ
আম বিশ্বের সেরা ফল। স্বাদে, গন্ধে আর পুষ্টিমান বিবেচনায় কোনো ফলই এর সমান নয়। তাইতো আমকে বলা হয় 'ফলের রাজা'। জাতীয় গাছের নামকরণও এর দখলে। মাননীয় প্রধানমন্ত্রী ২০১০ খ্রিস্টাব্দে মন্ত্রীপরিষদের এক সভায় আমগাছকে জাতীয় বৃক্ষ হিসেবে ঘোষণা দেন। এ খেতাব দেয়া যুক্তিও আছে অনেক। যেমন: মুজিবনগর সরকার গঠন হয় মেহেরপুরের বৈদ্যনাথতলার এক আম্রকাননে, মহান ভাষা আন্দোলনের গুরুত্বপূর্ণ সিদ্ধান্তগুলো নেয়া হয় ঢাকা বিশ্ববিদ্যালয়ের আমতলায় বসে। আমাদের জাতীয় সংগীতেও আমের কথা উল্লেখ রয়েছে।
আমের আকার-আকৃতি হরেক রকমের। ছোট, বড়, মাঝারি। আবার গোলাকার, লম্বাটে চ্যাপ্টা, সরু। কচি অবস্থায় সব আম দেখতে সবুজ। কিন্তু পাকলে জাতের ভিন্নতায় রঙও হয় আলাদা। স্বাদে কোনোটি টক, হালকা টক। কোনোটি আবার মিষ্টি, অতিমিষ্টি, পানসেও হয়। আঁশযুক্ত, আঁশহীনও থাকে। একেকটির গন্ধ একেক ধরনের । কাঁচা ও পাকা উভয় অবস্থায় খাওয়া যায়। কাঁচা আমে ভিটামিন-সি এবং পাকা আমে রয়েছে প্রচুর পরিমাণ ভিটামিন-এ।
পুষ্টিবিজ্ঞানীদের মতে, এর প্রতি ১০০ গ্রাম পাকা ফলে (আহারোপযোগী) আমিষ ১ গ্রাম, শর্করা ২০ গ্রাম, চর্বি ০ দশমিক ৭ গ্রাম, খনিজ পদার্থ ০ দশমিক ৪ গ্রাম, ক্যালসিয়াম ১৬ মিলিগ্রাম, লৌহ ১ দশমিক ৩ মিলিগ্রাম, ক্যারোটিন ৮৩০০ মাইক্রোগ্রাম, ভিটামিন-বি১ ০ দশমিক ১০ মিলিগ্রাম, ভিটামিন-বি২ ০ দশমিক ০৭ মিলিগ্রাম, ভিটামিন-সি ৪১ মিলিগ্রাম এবং খাদ্যশক্তি রয়েছে ৯০ কিলোক্যালরি। আমের তৈরি জুস, মোরব্বা, জেলি, স্কোয়াশ খেতে খুবই সুস্বাদু। এছাড়া চাটনি, আচার, আমসত্ব, আমসি, আমচুর, কেচাপ এগুলো বেশ লোভনীয় খাবার। আম শুধু মজাদার ফলই নয়, এর ঔষধিগুণও আছে অনেক। আয়ুর্বেদি ও ইউনানী চিকিৎসায় আমকে বলা হয় টনিক, যা শরীরে শক্তি সৃষ্টি করে। আমে পর্যাপ্ত পরিমাণ অ্যান্টিঅক্সিডেন্ট আছে, যা স্তন, কোলন ও প্রোস্টেট ক্যান্সার প্রতিরোধক হিসেবে কাজ করে। লিভার ও কিডনির জন্য হিতকর। অ্যাজমা, হিটস্ট্রোক ও স্কার্ভি রোগের জন্য বেশ উপকারি। পাকা আম ফোড়া প্রতিরোধক, রক্ত পরিষ্কারক; সে সাথে স্মৃতিশক্তিও বৃদ্ধি করে। প্রজননতন্ত্রকে করে শক্তিশালী। আমের সাথে দুধ মিশিয়ে খেলে বল এবং তেজ দু'টোই বাড়ে। আম রাতকানা প্রতিরোধি ফল। নিয়মিত খেলে চোখের দৃষ্টিশক্তি বাড়ে। শরীরের ওজন কমায়। কিডনিতে পাথর হওয়ার ঝুঁকি কমিয়ে দেয়। আয়রনের পরিমাণ বেশি থাকায় অ্যানিমিয়া হতে বাঁধা দেয়। গর্ভবতী মহিলাদের ক্যালসিয়াম এবং লৌহের ঘাটতি পূরণে আম অনন্য। আম রক্তের কোলেস্টেরল কমায়। পরিপাকক্রিয়া সচল রাখে। শুষ্কতা দূর করে ত্বক রাখে মসৃণ-মোলায়েম। দাঁত ও নখকে করে মজবুত। চুল পড়া আর খুশকি রোধেও কাজ করে বেশ। পেট ভরে আম খেলে ঘুমজনিত সমস্যা দুর হয়। একটি কথা না বললেই নয়। যারা ডায়াবেটিস রোগি তাদের পাকা আম না খাওয়াই ভালো। তবে টক জাতীয় আম খাওয়া যাবে ইচ্ছে মতো।
আমের বিচিরও উপকারিতা আছে। রমণীদের চুলের সৌন্দর্য বাড়াতে এর জুড়ি নেই। এজন্য আমের বিচির শাঁস শিলপাটায় বেটে নিতে হয়। এরপর কাচের বোতল ঢুকিয়ে পরিমাণমতো নারকেল তেল দিয়ে ভালোভাবে মেশাতে হবে। তিল, সরিষা কিংবা জলপাই তেলও দেয়া যাবে। এবার সপ্তাহখানিক রোদে রেখে নিয়মিত ব্যবহার করতে হবে। তাহলে চুল হবে কালো, লম্বা ও পুরু। সবার দৃষ্টিনন্দন।

Articles, Poetry, Rhymes & Write up / মা দিবস
Last post by zarkasultana - May 14, 2023, 03:54 PMআজ বিশ্ব মা দিবস। সর্ব প্রথমে মা দিবসের প্রচলন হয় যুক্তরাষ্ট্রে। দিবসটি প্রচলন করেন আনা মারিয়া রিভস জর্ভিস। এই দিনে সব সন্তানেরা চিঠি লিখে মাকে ভালোবাসার কথা বলে, বিভিন্ন উপহার দেয়। মা খুশি হন।
কিন্তু 'মা' শব্দটি এই একদিনের ভালবাসা এবং উপহার দেওয়ার জন্য নয়, মা এক সর্বত্যাগী শব্দের নাম। যিনি সন্তানের জন্য নিজেকে উৎসর্গ করেন। মা - যিনি সন্তানকে বছরের পর বছর কোলে নিয়ে ৮-১০ মাইল হেঁটে সন্তানকে ডিগ্রী পাস করান। মা- যিনি অস্বাভাবিক সন্তানকে বুকে আগলে যত্ন করে তার সমস্ত ভার বহন করেন ক্লান্তহীনভাবে। মা- নিজে না খেয়ে সন্তানের মুখে খাবার দেন আর বলেন, আমার এগুলো খেতে ভালো লাগে না অথবা আমার খিদে নেই। মা- বৃদ্ধ বয়সে সারাদিন ভিক্ষা করার পরও দিনশেষে আল্লাহকে বলে আমার সন্তানদের তুমি ভালো রেখো।
শতকোটি সালাম জানাই সেই সব মায়েদের আর কামনা করি পৃথিবীর সব সন্তান বৃদ্ধ অসুস্থ মাকে তার সর্বোচ্চ সেবা টুকু উপহার দিক।
বিশ্ব মা দিবসে সকল মায়ের প্রতি রইল শ্রদ্ধা ও ভালোবাসা।।

Articles, Poetry, Rhymes & Write up / The Human–Nature Relationship ...
Last post by tamannabiva - May 02, 2023, 06:20 AMThe Human–Nature Relationship and Its Impact on Health
During the last century, research has been increasingly drawn toward understanding the human–nature relationship (1, 2) and has revealed the many ways humans are linked with the natural environment (3). Some examples of these include humans' preference for scenes dominated by natural elements (4), the sustainability of natural resources (5, 6), and the health benefits associated with engaging with nature (7–9).
Of these examples, the impacts of the human–nature relationship on people's health have grown with interest as evidence for a connection accumulates in research literature (10). Such connection has underpinned a host of theoretical and empirical research in fields, which until now have largely remained as separate entities.
Since the late nineteenth century a number of descriptive models have attempted to encapsulate the dimensions of human and ecosystem health as well as their interrelationships. These include the Environment of Health (11), the Mandala of Health (12), the Wheel of Fundamental Human Needs (13), the Healthy Communities (14), the One Health (15), and the bioecological systems theory (16). Each, however, have not fully incorporated all relevant dimensions, balancing between the biological, social, and spatial perspectives (17, 18). In part this is due to the challenges of the already complex research base in relation to its concept, evidence base, measurement, and strategic framework. Further attention to the complexities of these aspects, interlinkages, processes, and relations is required for a deeper sense of understanding and causal directions to be identified.
t is beyond the scope of this paper to review the various connections at the intersect of humanity and the natural environment. Instead, I summarize key concepts and approaches from those four research fields (Evolutionary Biology, Social Economics, Evolutionary Psychology, and Environmentalism) outlined below, which have paid most attention to studying this research area. I then summarize areas of convergence between these connections in an attempt to describe the human–nature relationship, which will serve as background to this review.
It is anticipated that through drawing on these different fields of knowledge, a deeper level of understanding can be brought to the growing issue of humanity's relationship with nature and its impact on health. This is because examining the human–nature relationship from a single disciplinary perspective could lead to partial findings that neglect other important sources as well as the complexities that exist between interlinkages, causal directions, processes, and relations.
Evolutionary Biology
Evolutionary biology is a branch of research that shortly followed Darwin's (20) Theory of Evolution. It concerns the adaptive nature of variation in all animal and plant life, shaped by genetic architecture and developmental processes over time and space (21). Since its emergence over a century ago, the field has made some significant advances in scientific knowledge, but with intense debate still remaining among its central questions, including the rate of evolutionary change, the nature of its transitional processes (e.g., natural selection) (22). This in part owes to the research field's interdisciplinary structure, formulated on the foundations of genetics, molecular biology, phylogeny, systematics, physiology, ecology, and population dynamics, integrating a diverging range of disciplines thus producing a host of challenging endeavors (23, 24). Spanning each of these, human evolution centers on humanity's life history since the lineage split from our ancestral primates and our adaptive synergy with nature.
In the last four decades, evolutionary biology has focused much attention on the cultural–genetic interaction and how these two inherent systems interrelate in relation to lifestyle and dietary choices [Culturgen Evolution (25); Semi-Independent (26); Dual-Inheritance model (27)]. Some of the well-known examples include humans' physiological adaptation to agricultural sustenance (28), the gradual increase in lactose tolerance (29) as well as the susceptibility of allergic diseases (e.g., asthma and hay fever) in relation to decreasing microbial exposure (30).
This coevolutionary perspective between human adaptation and nature has been further conceptualized by Gual and Norgaard (31) as embedding three integrated systems (biophysical, biotic, and cultural). In this, culture is both constrained and promoted by the human genetics via a dynamic two-way interaction. However, bridging the gap between these research fields continues to generate much controversy, particularly as the nature of these evolutionary development processes differs widely (e.g., internal and external factors). This ongoing discussion is fueled by various scholars from multiple disciplines. Some have argued that one cannot assume all evolutionary mechanisms can be carried over into other areas (32, 33), where genomes cannot evolve as quickly to meet modern lifestyle and dietary requirements (34). Conversely, others believe that humans have not entirely escaped the mechanisms of biological evolution in response to our cultural and technological progressions (35).
Evolutionary Psychology
Evolutionary psychology is a recently developed field of study, which has grown exponentially with interest since the 1980s. It centers on the adaptation of psychological characteristics said to have evolved over time in response to social and ecological circumstances within humanity's ancestral environments (36–38). This reverse engineering approach to understanding the design of the human mind was first kindled by evolutionary theorist Charles Darwin (20) in the last few pages of Origin of Species;
In the distant future ... Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation [p. 447].
As such, evolutionary psychology is viewed by some to offer a metatheory that dissolves the traditional boundaries held in psychology (e.g., cognitive, social, personality, and development). Within this metatheory, all psychological theories implicitly believed by some to unify under this umbrella (37). However, the application of evolution to the study of psychology has not been without controversial debate in areas relating to cognitive adaptation, testability of hypotheses, and the uniformity of human nature (39).
During the past few decades, the field has presented numerous concepts and measures to describe human connectedness to nature. These include Deep Ecology (40), Extinction of Experience (41), Inclusion of Nature in Self (42), and Connectedness to Nature (43). However, the Biophilia hypothesis (44) remains the most substantially contributed to theory and argues for the instinctive esthetic preference for natural environments and subconscious affiliation for other living organisms. Supportive findings include humans' preference for scenes dominated by natural elements (4), improved cognitive functioning through connectivity with nature (45) as well as instinctive responses to specific natural stimuli or cues (e.g., a common phobia of snakes) (46). More recently, evidence is emerging to suggest that connectivity to nature can generate positive impacts on one's health, increasing with intensity and duration.
Environmentalism can be broadly defined as an ideology or social movement. It focuses on fundamental environmental concerns as well as associated underlying social, political, and economic issues stemming from humanity's interactions affecting the natural environment (67, 68). In this context, the human–nature relationship has been explored through various human-related activities, from natural resource extraction and environmental hazards to habitat management and restoration. Within each of these reflects a common aspect of "power" visible in much of the literature that centers on environmental history (69). Some examples included agricultural engineering (70), the extinction of animals through over hunting (71) as well as the ecological collapse on Easter Island from human overexploitation of natural resources, since disproven (72–74). Yet, in the last decade, the field's presupposed dichotomy between humans and nature in relation to power has been critically challenged by Radkau (75) who regards this perspective as misleading without careful examination. Instead, they propose the relationship to be more closely in synchrony.'

Allah, Quran & My belief / Belief in Holy Quran
Last post by aliarawshan - Apr 13, 2023, 11:35 AMBelief in Holy Quran
Belief in the Holy Quran is central to the Islamic faith, and Muslims hold it in the highest regard. It is believed to be a miraculous revelation that contains guidance for all aspects of life, including matters of spirituality, morality, social justice, family, and personal conduct. Muslims believe that the Quran is a complete and perfect revelation from God, preserved in its original form without any changes or alterations, and that it is the final and complete revelation to humanity.
Muslims are encouraged to read, understand, and follow the teachings of the Quran in their daily lives. It is often recited in daily prayers, and its teachings are used as a source of guidance in making moral and ethical decisions. Muslims also strive to live according to the principles and values outlined in the Quran, such as compassion, justice, humility, and piety.
Belief in the Holy Quran also entails respect for its physical form, with Muslims handling it with utmost reverence and care. It is considered a sacred object and is treated with great respect, often kept in a clean and elevated place, and handled with ritual purity.
In summary, belief in the Holy Quran is a fundamental aspect of Islamic faith for Muslims, who consider it to be the ultimate source of guidance and a divine revelation that shapes their beliefs, practices, and way of life.
