A Study on the Measurement Method of Biot Coefficient for Concrete Based on Experimental Approaches
Authors: Hu Yintao , Ru Nan , Zhou Qiujing , Cheng Heng , Zhang Guoxin
Published: November 2024

Concrete stress is a key factor influencing the operational safety of concrete dams, and understanding the true distribution and variation of stress is a major research focus in the field of dam engineering. In the heel region of the dam, internal voids in the concrete may allow external water infiltration under high hydraulic head, leading to changes in the concrete’s elastic modulus and Biot coefficient. These changes, in turn, affect the effective stress experienced by the concrete. Consequently, the measured stress in the heel and toe regions may differ from conventional understanding and standard calculation methods for dam stresses. This is particularly evident in the following aspects: after water impoundment, compressive stress in the dam heel is higher than in the dam toe, with the heel stress exceeding the calculated value by a significant margin, and the variation in stress during the impoundment process being smaller than the calculated value. To address these issues, this paper proposes a theoretical method for measuring the Biot coefficient of concrete through experimental testing and innovatively develops the corresponding experimental equipment. This equipment can accurately simulate the conditions of the dam under different water depths (confining pressures) and measure the deformation of concrete caused by changes in water depth. Based on this equipment, tests were conducted on the elastic modulus and Biot coefficient of dry and saturated concrete specimens under different confining pressures. The Voigt–Reuss–Hill mixed average modulus formula was applied to calculate the elastic modulus of the concrete matrix, exploring the influence of pore water on the mechanical properties of the concrete. The results indicate that the pore water inside the concrete increases its equivalent elastic modulus during the testing process. In numerical simulations of the dam, this increased modulus due to pore water is often overlooked, leading to an underestimation of the results. This partially explains why the measured compressive stress in the dam heel consistently exceeds the calculated values. According to the Biot coefficient calculation theory proposed in this paper, the Biot coefficient of concrete varies with its water content. The Biot coefficient is lower in specimens with high water content compared to those with low water content. Using the Voigt–Reuss–Hill mixed average modulus formula, the elastic modulus of the concrete matrix obtained from the tests was found to be 28 GPa, which is in good agreement with the results from regression analysis. These findings are of significant importance for the safe operation of concrete dam engineering.

Graphene oxide-mediated photothermal therapy using femtosecond lasers has recently shown promise in treating hepatocellular carcinoma. However, significant work remains to optimize irradiation parameters for specific nanoparticle types and cancer cells to improve nanomaterial-mediated photothermal anticancer therapy. This study investigated the photothermal potential of nGO and nGO-PEG nanoparticles (NPs) combined with femtosecond laser irradiation at 515 nm and 1030 nm wavelengths, with varying power (0.1 and 0.2 W/cm2) and duration (5 and 10 min), to optimize photothermal therapy for hepatocellular carcinoma. Conversion efficiency of NPs, morphology and viability of HepG2 and normal MDCK cells after treatments were evaluated using an electronic thermometer, phase-contrast microscopy, and WST-1 assay. The results revealed that nGO-PEG NPs exhibited better photothermal efficiency than nGO, with 515 nm of irradiation inducing a temperature increase up to 19.1 °C compared to 4.7 °C with 1030 nm of light. Laser exposure to 515 nm significantly reduced HepG2 cell viability, with the most intense conditions (10 min at 0.2 W/cm2) causing a decrease of up to 58.2% with nGO and 43.51% with nGO-PEG. Normal MDCK cells showed minimal impact or a slight viability increase, especially with nGO-PEG. Combined treatment with laser irradiation and NPs induced significant morphological changes in HepG2 cells, including cell detachment and apoptotic-like characteristics, particularly with 1030 nm of irradiation. MDCK cells exhibited minimal morphological changes, with some recovery observed under lower energy conditions. These findings suggest that low-energy lasers and engineered nanomaterials could provide a minimally invasive approach to photothermal cancer therapy with reduced side effects.

Authors: Liu Jin , Zhou Feng , Tang Yang , Li Linghui , Li Ling
Published: November 2024

Lactate, once viewed as a byproduct of glycolysis and a metabolic “waste”, is now recognized as an energy-providing substrate and a signaling molecule that modulates cellular functions under pathological conditions. The discovery of histone lactylation in 2019 marked a paradigm shift, with subsequent studies revealing that lactate can undergo lactylation with both histone and non-histone proteins, implicating it in the pathogenesis of various diseases, including cancer, liver fibrosis, sepsis, ischemic stroke, and acute kidney injury. Aberrant lactate metabolism is associated with disease onset, and its levels can predict disease outcomes. Targeting lactate production, transport, and lactylation may offer therapeutic potential for multiple diseases, yet a systematic summary of the small molecules modulating lactate and its metabolism in various diseases is lacking. This review outlines the sources and clearance of lactate, as well as its roles in cancer, liver fibrosis, sepsis, ischemic stroke, myocardial infarction, and acute kidney injury, and summarizes the effects of small molecules on lactate regulation. It aims to provide a reference and direction for future research.

Published: November 2024

A endodontia visa erradicar bactérias e seus subprodutos do interior do canal radicular, objetivando interromper a infecção e permitir a preservação de elementos dentários que, sem esse tratamento, estariam comprometidos, evitando assim danos à saúde oral do paciente. Nas diversas etapas do tratamento endodôntico, o profissional pode enfrentar desafios que aumentam a suscetibilidade a erros. Esses desafios podem decorrer de limitações dos instrumentos utilizados, particularidades anatômicas dos dentes tratados ou mesmo da insuficiência de conhecimento e habilidade técnica do dentista. A combinação desses fatores pode impactar diretamente no sucesso do procedimento e na manutenção da saúde oral do paciente. Este trabalho teve como objetivo geral investigar as principais técnicas e procedimentos utilizados na remoção de instrumentos fraturados durante tratamentos endodônticos. A metodologia utilizada neste trabalho foi a revisão bibliográfica. Conclui-se que o conhecimento detalhado das técnicas de remoção de instrumentos fraturados e a contínua evolução das ferramentas disponíveis são essenciais para avançar na prática da endodontia e garantir o sucesso no tratamento de complicações potencialmente comprometedoras.

O nódulo de Schmorl é uma herniação focal que atravessa o disco intervertebral, produzindo uma marca permanente facilmente observada na superfície óssea vertebral. Tal patologia acarreta em dano estrutural a um dos pilares do corpo humano. A análise de restos humanos parcial ou totalmente esqueletizados fornecendo o perfil bioantropológico, no Brasil esses achados ainda são comparados com métricas estrangeiras, restringindo a identificação humana brasileira, devido sua alta miscigenação. Este estudo visa identificar a prevalência dos nódulos de Schmorl no segmento torácico da coluna vertebral em ossadas humanas contemporâneas. Trata-se de um estudo quantitativo transversal de caráter descritivo realizado no Laboratório de Identificação Humana e Osteologia Forense e no Laboratório de Antropologia e Osteologia Forense da Universidade Federal de Pernambuco, Brasil. Foram selecionadas 137 ossadas humanas contemporâneas de ambos os sexos. Dividiu-se a coluna vertebral em região torácica superior de T-I à T-VI e torácica inferior de T-VII à T-XII, havendo observação minuciosa, identificando o nódulo de Schmorl. Os dados foram agrupados em tabelas, analisados quanto a frequência relativa e absoluta, e através do teste Qui Quadrado. Não houve diferença significativa entre os sexos. Os nódulos de Schmorl foram identificados em 225 vértebras torácicas, apresentando relação entre a prevalência e a região. O nódulo de Schmorl demonstrou maior presença nas vértebras torácicas inferiores. Houve maior quantidade de vértebras de indivíduos masculinos acometidas. O levantamento do perfil osteológico da população brasileira, contribui, portanto, para abertura de novos caminhos para estudos osteológicos que são potenciais ferramentas nas análises forenses em determinadas populações contemporâneas.

Published: November 2024

A luxação esternoclavicular, apesar de ser uma lesão traumática rara, pode apresentar risco de lesão de estruturas do mediastino e, portanto, deve ser conhecida por todo ortopedista. O diagnóstico é clínico-radiológico, por meio do exame físico e de imagem, necessitando por vezes de investigação complementar, principalmente quando há suspeita de lesão de estruturas nobres, para que seja realizado, idealmente, o tratamento com urgência. Os autores apresentam o caso de um paciente adulto jovem, vítima de acidente motociclístico com consequente luxação esternoclavicular posterior e, conseguinte compressão parcial do tronco braquiocefálico direito, com repercussão clínica decorrente desta. Submetido à redução aberta e fixação da articulação com fio de aço agulhado, foi obtida redução anatômica, com boa evolução do paciente, não havendo limitações observáveis ao seguimento ambulatorial. Por meio deste, são discutidas as particularidades desta afecção, bem como possíveis abordagens terapêuticas e o prognóstico.

Worker health and safety is a topic of great importance within organizations and for the government, as neglecting this issue can result in both damage to human capital and financial losses. Various data and information are generated from occurrences of diseases, accidents, and fatalities in the occupational realm, making it necessary to register, analyze, and monitor this topic. In Brazil, these events must be recorded through the opening of a Work Accident Communication, which are subsequently grouped by periods and made publicly available by Brazil's Social Security. In this study, these data are subjected to an exploratory analysis, aiming to examine cases of diseases, accidents, and fatalities in Brazil, as well as the attributes of the dataset. To this end, all available data up to now is utilized, covering the time frame from June 2018 to May 2023. Additionally, the focus of the analysis was on the manufacturing industry sector, which has the highest number of records (around 30%). The main contributions of the research seek to analyze the categories with the highest incidence for each attribute, as well as to identify missing values and outliers, in order to construct a new dataset that allows for future applications.
Participação, governança e tecnologia como elos para que se revelem as cidades inteligentes
Authors: Coelho Vitor Daher
Published: November 2024

A concentração da população mundial em centros urbanos, mesclada com a crescente presença da tecnologia no cotidiano das pessoas, tem colaborado para que gestões municipais procurem aumentar a sua presença digital, tentando se definir “inteligentes”. Este fenômeno é crescente interesse acadêmico, pesquisadores procuram definir o que seria uma cidade inteligente e quais elementos devem estar atrelados a estas iniciativas. O campo tem sido marcado por divergências quanto a estas definições e isto pode ser explicado em função da orientação teórica dos autores dos estudos, enquanto a tradição funcionalista tende a propor modelos com menor carga de transformação da dinâmica social, abordagens alternativas dão destaque às possiblidades de mudanças que estão atreladas a estes processos. Este trabalho tem como objetivo elaborar uma breve revisão bibliográfica das produções sobre cidades inteligentes, para em seguida articular o tema com a Teoria Ator-Rede (TAR). Entendemos que esta teoria é capaz de captar as nuances da relação entre elementos humanos e não humanos de forma a evidenciar que uma verdadeira construção social de cidade inteligente deve contemplar estes dois elementos em conjunto, ao contrário de concebê-los de forma exclusiva ou antagônica, como é possível encontrar em alguns estudos. Cumprida esta etapa, discutiremos a relação entre participação cidadã, modelos de governança e tecnologia para então apresentarmos uma proposta de classificação dos estudos sobre cidades inteligentes a partir da maneira como eles tratam os elementos centrais: um eixo que distingue os trabalhos entre os focados nos recursos humanos ou nos recursos tecnológicos e outro eixo que separa as abordagens entre as proposições implementação de políticas do tipo “top-down” e as que sugerem políticas no formato “bottom-up”. Por fim, apresentaremos sugestões para futuras pesquisas empíricas de cidades inteligentes.

Authors: Culi Mario Jose Lucero , Contrera Ronan Cleber
Published: November 2024

Os resíduos sólidos possuem um potencial energético importante, e que normalmente é dissipado em aterros sanitários perdendo essa capacidade de gerar energia de forma sustentável. O CEAGESP gerou no ano 2015 uma quantidade de 60.195 t ano-1, e para o ano 2035 de acordo ao modelo linear será de 115.064,7 t ano-1. De essa quantidade de resíduos uma porcentagem é reciclada, para o ano 2015 a quantidade reciclada foi de 24,3%; o resto foi enviado para aterro sanitário. Entre os diversos tipos de tratamento para os resíduos sólidos se encontra a digestão anaeróbia, a qual permite gerar biogás, como resultado da ação metabólica dos microrganismos, que pode ser aproveitado para geração de calor ou eletricidade. Diversos tipos de tecnologia permitem tratar os resíduos por digestão anaeróbia, entre as quais destacam o processo DICOM, DRANCO, BIOCEL, BTA, VALORGA, SEBAC e KOMPOGAS. De acordo aos cálculos do potencial energético através dos diversos processos este oscila entre 3,1 MW (processo BioCEL) até 7,0 MW (DRANCO) para o ano 2015; e para o ano 2035, 5,9 MW (BioCEL) e 13,5 MW (DRANCO). A geração de biogás obtida em base aos dados de geração das diversos tecnologias foi entre 73.454 m3 de biogás (BioCEL) e 127.132 m3 de biogás (DRANCO) para o ano 2015; e para 2035 a geração seria de 140.410 m3 de biogás (BioCEL) e 243.017 m3 de biogás (DRANCO). O número de residências para abastecer de eletricidade estaria na média em 769 para o ano 2015 e 1469 para o ano 2035.

Published: November 2024

Wheat is one of the major important cereal crops in the world. In agriculture, fungal diseases pose significant constraints on wheat production. Fusarium is a major pathogenic and toxic fungus that widely affects wheat. This study aimed to identify and characterize Fusarium species, with a particular interest in detecting toxigenic strains. Thirty-one samples of wheat plants showing typical symptoms were collected from 7 different regions in western Algeria in 2021. Fusarium species were found in 63% of the samples. On the basis of their morphological characteristics, 53 strains of Fusarium were isolated and preserved. Eleven Fusarium species were identified on the basis of phylogenic analyses with the translation factor TEF-1α. Among these Fusarium isolates, 6 were identified as F. pseudograminearum, 2 as F. acuminatum, 2 as F. algeriens, and 01 as F. oxysporum. Pathogenicity tests demonstrated that all eight Fusarium species tested (F. psedograminearum, F. algeriens, and F. acuminatum) could cause typical symptoms of FCR in wheat in these provinces. F. algeriens is the most aggressive pathogenic species, and it is the second most common isolate of this pathogen in Algeria.

Published: November 2024

Tylenchulus semipenetrans is a key nematode pest of citrus, responsible for the ‘slow decline’ disease. It is distributed in almost all citrus-growing countries worldwide. These nematodes primarily infect feeder roots, which affects the uptake of water and soil nutrients. Plants infected by the nematode yield fewer fruits, which are also smaller in size. Chemical control is widely used for protection, improvement, and acceleration of agricultural yield; however, it poses risks to human health and the environment, affecting fruit toxicity and harming beneficial fauna. This highlights the need for specific alternatives. In this study, we will conduct in silico experiments to identify the most effective enzyme-ligand complexes that lead to the best inhibitors of Acetyl CoA Carboxylase in the citrus nematode Tylenchulus semipenetrans. The Acetyl CoA Carboxylase enzyme is responsible for fatty acid synthesis in Tylenchulus semipenetrans, and its disruption affects the synthesis of the surface layer. This inhibitory action is based on the essential oils of plants.The advantages of this method include absolute specificity, absence of toxicity, and significant efficiency in crop protection, achieved through molecular modeling techniques.

Published: November 2024

Belas kasih akan tetap mandul bila tumbuhnya ke dalam diri sendiri. Di samping itu, bila belas kasih terfokus pada diri sendiri berakibat kurang sehat dan kelihatan kurang maksimal untuk sebuah penggembalaan. Justru berdasarkan pengalaman penggembalaan di Chatillon les Dombes, Vinsensius ingin mengubah hidup manusia yang cenderung ego sentris menjadi Kristus sentris. Artinya, Kristus menjadi pusat hidup dan sumber belas kasih yang menggerakkan orang ke luar dari diri sendiri dan mulai bertindak dan membantu sesama. Kisah Chatillon sejatinya mau mendobrak kepalsuan hidup manusia yang tampak ingin membentengi diri dengan rasa nyaman, malas gerak, tidak mau berbagi dan jatuh dalam egoisme diri yang parah. Vinsensius memberi kontribusi sangat besar bagi kemajuan misi Gereja sebab ia mampu menggerakkan awam, umat Allah terutama wanita terlibat aktif dan berpartisipasi mewujudkan misi Tuhan. Alih-alih mengarah dalam diri sendiri, belas kasih mesti tumbuh ke luar; menjangkau lebih luas jiwa-jiwa dan memberikan energi lebih besar dengan melayani sesama. Kontribusi terbesar Vinsensius menjadikan orang lain memiliki belas kasih dan supaya mereka berani menginspirasi belas kasih itu pada orang lain dan menunjukkan jalannya.

Jurusan Teknik Perkapalan adalah salah satu jurusan yang ada dikampus Politeknik Negeri Bengkalis. Jurusan Teknik Perkapalan Memiliki Musala yang baru dibangun dan diresmikan pada tanggal 8 Maret 2024 yang bernama Musala Darul Ilmi. Pada saat ini Musala Darul Ilmi belum memiliki media informasi jam waktu sholat secara otomatis dan juga media informasi jadwal imam dan muazin serta informasi keuangan. Hal tersebut sangat dibutuhkan untuk kelancaran proses ibadah. Namun dengan adanya masalah ini penulis memberikan solusi dengan membuatkan jam waktu sholat menggunakan running text dengan controller yang memiliki fitur bisa  secara otomatis menentukan jam waktu sholat berdasarkan garis lintang dan bujur. Selain itu jam controller ini dapat menampilkan kelender hijriah, buzzer otomatis ketika waktu sholat tiba, menampilkan pesan, jadwal imam dan muazin, menampilkan laporan keuangan, tartil otomatis, dan azan otomatis yang nantinya akan dipasang pada Musala Darul Ilmi Jurusan Teknik Perkapalan. Sehingga dengan adanya jam waktu sholat berbasis running text ini, semua informasi keagamaan dan ibadah bisa tersampaikan mudah dan otomatis.

Pulau Bengkalis termasuk kedalam Kabupaten Bengkalis, Provinsi Riau. Pulau bengkalis merupakan salah satu penghasil ikan air laut dan ikan air tawar yang cukup besar. Salah satu desa yang mata pencahariannya ikan adalah Desa Tasik S erai, Dusun Bagan Benio, Kec. Tualang Mandau, Kab. Bengkalis. Desa ini terletak cukup jauh dari jalan raya, karena permukiman yang terpencil, mulai dari infrastruktur jalan yang masih terbatas, infrastruktur listrik yang tidak memadai, transpotasi yang kurang baik Pendidikan, kesehatan, banjir dan lingkungan. Dengan mayoritas nelayan dan karet, desa ini memiliki cukup banyak penghasilan ikan dalam perharinya, namun kurangnya akses untuk menjualkan hasil tangkapan dalam kondisi segar membuat para nelayan kesulitan dalam perekonomian. Jadi ada beberapa yang memilih ikan tersebut di salai dengan alat tradisonal, namun alat pengasapan ini masih dibilang kurang higienis karena masih dalam kondisi terbuka, menambah polusi, dan hal - hal buruk lainnya. Dari potensi  dan permasalahan di atas, kami memiliki solusi yang bisa membantu para nelayan di desa Bagan Benio tersebut. Perpecahan atau solusi nya yaitu membuat tungku pengasapan ikan yang lebih baik, dengan bentuk seperti lemari, dan menggunakan bahan bakar kayu, tungku ini dibuat untuk mempermudah proses pengasapan dan pengeringan ikan, sehingga para nelayan dapat lebih cepat mengolah hasil tangkapannya untuk diperjual belikan. Tujuannya agar tidak ada lagi ikan yang terbuang sia-sia karena lamanya perjalanan ke jalan raya, maka dari itu lebih baik jika ikan tersebut di asapkan (salai) dan dikeringkan.

Untuk itu perlu dirancang suatu alat pemotong rumput yang efisien dan dapat mengurangi resiko kecelakaan dalam menggunakan peralatan tersebut dengan memodofikasi mesin rumput tipe gendong menjadi tipe dorong dengan roda untuk mengurangi resiko kecelakaan kerja seperti terkena paku, batu dan pisau serta mengurangi kelelehaan operator terutama tukang kebun.
ТИПОЛОГІЇ МОДЕЛЕЙ ЗМІШАНОГО НАВЧАННЯ: ЗАРУБІЖНИЙ ДОСВІД
Authors: Сотська Галина , Тринус Олена
Published: November 2024

Змішане навчання – це освітня стратегія, яка поєднує традиційні методи викладання в аудиторії з онлайн-активностями, що кардинально змінює формат здобуття освіти, враховуючи освітні потреби сучасних здобувачів освіти, створюючи персоналізований освітній досвід. Розвиток технологій і зростання попиту на гнучкі освітні рішення сприятиме посиленню ролі змішаного навчання та потребуватиме вирішення питання осмислення можливостей впровадження його моделей для реалізації освітніх програм закладів вищої освіти. У статті розглянуто окремі моделі змішаного навчання та їх класифікації, створені зарубіжними дослідниками (К. Твігг (2003); Г. Смітом та Х. Куртеном (2007); Е. Аллен та Д. Сіманом (2010); Х. Стакер та М. Хорном (2012); В. Ірвін (2013)  Ч. Грехемом (2014); Е. Піччіаном (2017); Х. Фармер (2020)). Встановлено, що у зв’язку з існуванням різноманітних варіантів поєднання компонентів змішаного навчання та відсутністю науково обгрунтованої критеріальної основи їх систематизації на сьогодні не розроблено загальноприйнятої типології моделей змішаного навчання. У зарубіжній практиці в якості критеріїв використовуються, зокрема, кількісний, що враховує модальні, технологічні характеристики (частка використання електронного складника, тип гібридності; засоби, що використовуються тощо) та якісний, що враховує педагогічні параметри (характер взаємодії учасників освітнього процесу, вибір форм і методів навчання). На основі аналізу досліджень зарубіжних учених запропоновано критерії для класифікації моделей змішаного навчання, пов’язані з: їх цільовим спрямуванням; рівнем впровадження; врахуванням часткового співвідношення очного та електронного компонентів; ступенем персоналізації; особливостями організації навчання тощо.
Naturaly-ecological framework of the Republic of North Оssetia—Аlania
Authors: Tebieva Delyara , Dobronosov Vitaliy
Published: November 2024

The existing structure of specially protected natural territories of the Republic of North Ossetia—Alania is considered. An option is proposed to improve the natural and ecological frame by creating a specially protected natural area in the form of a geopark in the east of the mountainous part of the republic and including wetlands valuable in environmental and scientific terms—the “Bekan” Reservoir and the Tarskoe peat bog in the frame structure. In the conditions of the tourism industry intensively developing in the Republic of North Ossetia—Alania, the geopark is the most suitable form of protected area. Unlike protected areas already operating on the territory of the Republic of North Ossetia—Alania, the geopark has less stringent restrictions on nature management. The security regime of the geopark is formed due to the presence of unique geological and geomorphological objects and processes and extends to objects of cultural and historical heritage located on the same territory. The paper uses materials obtained over a long period of complex geographical studies of the region. The current state of tourist nature management was studied directly in areas of greatest tourist interest. The ecological state of individual natural and cultural objects was revealed in the field. Cartographic work on the planned geopark was carried out using a single technology in the CorelDRAW, Photoshop and Surfer programs. The comparative approach was used to justify the optimization of the structure of protected areas and the improvement of the natural and ecological framework of the territory of the Republic of North Ossetia—Alania. The proposed structure of the natural-ecological framework increases the area of specially protected areas by almost ten percent, while simultaneously increasing the level of protection of natural and cultural-historical monuments and objects, and generally increasing the attractiveness of the Republic of North Ossetia—Alania.
Suitability assessment of wind energy farming in the desert landscape of Zarafshan Valley, Uzbekistan
Authors: Suhail Mohammad , Khan Mohd Nazish , Ravshanov Alikul , Usmanov Marufdjan
Published: November 2024

Wind farm suitability analyses have been carried out to demarcate the potential zones in the Middle Zarafshan River basin. Uzbekistan’s major cities occupy the middle and lower Zarafshan Valley, which needs to allocate and develop wind energy farms to restore sustainability. In the current study, the Middle Zarafshan valley was assessed to provide a synoptic view of potential zones for wind energy. This study aimed to develop a geospatial method to identify optimal locations in the valley. To accomplish this task, five criteria were considered: wind speed, slope, distance from the transmission network, road network, land use, and land cover. Further, each criterion was assigned a weight according to expert opinions and published research outcomes. In addition, a maximum of 45 % weight was assigned to wind speed, followed by land use, land cover, slope, and others. Further, these criteria were categorized into four classes viz., unsuitable, less suitable, moderately suitable, and highly suitable. Further, different thematic layers were produced to realize this study. Wind speed maps were derived at different heights to calculate the results and integrate them with other derivatives. The findings of this study show that the maximum intensity of winds received at 100 m height or more, and more than 40 % area of the study area was estimated suitable for wind energy exploitation.
