Authors: Chaudhary Dr. Sunita
Published: January 2022

This paper will explain the concept and need for the serverless architecture. In this concept the need for separate infrastructure to install application is not there. In order to exchange data, client and servers are needed where client will raise query to the server and the centralised server which has the information will respond with the results to the client. Here, the server is a centralised storage unit in which all the details are stored and that can be accessed remotely. In a server less architecture this server can be implemented without having the need for infrastructure which is known as serverless architecture. The paper will explain the process of implementation of the serverless architecture, its advantages, disadvantages, challenges and characteristics.

Published: January 2022

Cost, time and quality projection are the crucial aspects in software development process. Incorrect estimations can cause losses which in turn may lead to irreversible damage. It is generally perceived that a imperfectly estimated project always results in a substandard quality due to the efforts being wrongly directed. Firstly Effort Estimation is calculated by actual effort and proposed Effort. That Effort evaluation of 500 NASA projects, after that evaluation is done by four parameters Standard Error, Standard Deviation, Mean Absolute Error, Root Mean Square Error. The author amalgamated the robustness of COCOMO-II with that of Neural Network NN and Support Vector Machine SVM .Quality Which we evaluate that is quality Evaluation of Semantic Web Application. In the last checks the majority of all four parameters for software quality assessment.

Published: January 2022

Background and Aims: Hepatitis A virus is a cause of acute viral hepatitis that infects millions of people worldwide each year and maintains its prominence in both adults and in childhood. The aim of this study was to determine the hepatitis A seroprevalence in different age groups in Çorum which is the reference center for northern part of central Anatolia and to make recommendations for hepatitis A vaccine according to age groups. Materials and Methods: This retrospective study was conducted between January 2017 and January 2020. Patients tested for anti-hepatitis A virus for any reasons were enrolled from the data of all patients admitted to our hospital which is the reference center of the region. Serum samples were analyzed by ELISA. S/CO values of ≥ 1.00 were considered positive for anti-hepatitis A virus immunoglobulin G and immunoglobulin M, respectively; results below this value were considered negative. Anti hepatitis A virus immunoglobulin G and anti-hepatitis A virus immunoglobulin M results of patients were analyzed according to age groups. Results: A total of 18817 anti-hepatitis A virus immunoglobulin G and immunoglobulin M assays were screened from the computerized database. 4244 assays were excluded for repeated tests from the same patients and inconclusive data. The study included 4115 patients with anti-hepatitis A virus immunoglobulin M and 10458 patients with anti-hepatitis A virus immunoglobulin G. Total anti-hepatitis A virus immunoglobulin G and M positivities were 84.4% and 0.7%. Anti-hepatitis A virus immunoglobulin G prevalence was – 85.8% and 83%, and anti-hepatitis A virus immunoglobulin M positivity was – 0.98% and 0.38% in men and women. There was a significant difference in the prevalence of hepatitis A virus immunoglobulin G and immunoglobulin M according to age groups in Çorum (p < 0.001, p = 0.035). Anti-hepatitis A virus immunoglobulin G seronegativity for 11 - 20 years of age was 28.4% and for 21 - 30 years of age was 24.2%. Conclusion: This study suggests that 11 - 20 and 21 - 30 years of age groups may be in the highest risk group for hepatitis A virus infection with possible complications increasing with age, and this patient group constitutes the target population for vaccination.

Kolorektal kanserde lncRNA DPP10-AS1 ekspresyonu tümör baskılayıcı ve tümör mikroçevresinde metabolit transportuyla ilişkili olabilir mi?
Authors: NACARKAHYA Gülper , HOROZOĞLU Cem
Published: January 2022

Giriş ve amaç: Onkogen ve tümör baskılayıcı gen ifadeleri başta olmak üzere birçok RNA ve proteinle moleküler etkileşimde bulunabilen lncRNA’lar solid organ kanserlerinde ilişkilendirilmeye başlanmıştır. Deneysel çalışmalarda Wnt/β -katenin yolağı ile ilişkilendirilen lncRNA DPP10-AS1’in çalışmamızda kolorektal tümörlerdeki ifadesi ve serum biyobelirteçleriyle olan ilişkisinin incelenmesi amaçlanmıştır.

Gereç ve yöntem: Kolorektal kanser tanılı elli bir olgunun tümör ve tümörsüz çevre dokusuna ait formalinle fikse edilmiş parafine emdirilmiş bloklarından total RNA izolasyonu gerçekleştirildi. İzole edilen total RNA’dan lncRNA’lara spesifik c-DNA sentezi gerçekleştirildikten sonra DPP10-AS1’e özgü primerler ile gerçek zamanlı polimeraz zincir reaksiyonu ile ekspresyon düzeyi tespit edildi. Ekspresyon düzeyleri olguların serum biyomarkerlarıyla korelasyon yönünden incelendi.

Bulgular: lncRNA DPP10-AS1 ‘in katlı değişimi tümörsüz çevre dokusunda tümör dokusuna göre yaklaşık 5,7 kat yüksek olduğu tespit edilmiştir (P=0,0002). Histopatolojik bulgularla lncRNA DPP10-AS1 arasında istatistiksel bir farklılık tespit edilmezken, uzak organ metastazı olmayanlarda olanlara göre 1,5 kat yüksek olduğu izlenmiştir (p>0.05). DPP10-AS1 ile albümin (r: ,403; p=0,033) ve amilaz (r: ,450; p= 0,031) arasında pozitif korelasyonları tespit edildi.

Sonuç: DPP10-AS1’in tümör baskılayıcı rolü olduğunu, albüminle korelasyonu tümör mikroçevresinde sekonder metabolitlerin transportunda rol oynayabileceğini düşündürmektedir. DPP10-AS1 ile amilaz korelasyonunun literatürde tanımlanan yüksek amilaz düzeylerinin tümör farklılaşması, çoğalması sürecindeki etkisiyle paralele şekilde tümör mikroçevresinin bir yanıtı olarak ifade edilebileceğini düşünmekteyiz.
The Role of Institutional Linkages and Regional Institutions in the Location Choice of Outward Foreign Direct Investment: Empirical Evidence from Chinese Firms
Authors: Li Juan , Qu Yi , Wang Dayu , Zheng Nan
Published: January 2022

Differently from the prior studies that look at the determinants of Outward foreign direct investment (OFDI) location choice, based on the institution theory and employing a comprehensive and unique micro-level dataset of Chinese firms, this study is the first to integrate institutional linkages (Confucius Institute) and regional institutions into one framework and looks at the role of the location choices of Chinese OFDI. The results show that Chinese firms prefer to invest in countries with the presence and higher number of Confucius Institutes including Confucius classrooms. Moreover, the institutional linkage of Confucius Institutes can alleviate the possible negative effects caused by the distance between China and the host country, which suggests Confucius Institutes help Chinese firms against liabilities of foreignness and risks and costs of operation in more distant host countries. We also find that the availability and quality of China’s regional institutions have a strong impact on local firms’ willingness and capability of participating.

Published: January 2022

Education for sustainable development (ESD) has become a focus of international education attention, for its multidisciplinary character and for the interest in caring for the environment due to their degradation and environmental impact. This study compared two tests, one was conducted before confinement on 325 participants with 3545 responses, and one in confinement on 350 participants with 3832 responses. Surveys were conducted using Google Forms, based on 11 questions with its items verified by ANOVA and Bonferroni. The COVID-19 lockdown significantly influenced the results of both tests. The results indicated increased awareness of the environment during confinement. At the educational level it was intended to take an initial test and a year later perform a second test to compare them. The first test was carried out online at school, and the second one was held a year later in confinement due to COVID-19. This unexpected circumstance became an opportunity to value and compare them in different circumstances. Surveys were conducted using Google Forms. The results indicated a more significant concern for sustainability. The conclusion has been that students behave more sensitively to sustainable development in confinement circumstances.
Evaluation of the Application of an Inclusive Education Policy on Screening, Identification, Assessment and Support of the Learners at Schools in South Africa
Authors: Matolo Mantheme Florina , Rambuda Awelani M
Published: January 2022

The aim of this research was to evaluate the application of an inclusive education policy on screening, identification, assessment and support of learners (SIAS) policy at South African schools. The research explores how educators screen, identify, and assess barriers to learning as well as support learners with barriers. The variables on the screening, identification, assessment and support of learners were chosen as a focal point of this study mainly because they were all variables contained in the policy which must be mastered by the educators during the policy application. A survey design of quantitative research approach was followed. Document analysis of the SIAS 2014 policy document was done over the target population of educators in primary and secondary schools. A simple random sampling technique was used to select 320 male and female respondents from both primary and secondary schools. The quantitative data were collected using a seven-point semantic differential scale which elicited responses from a total of 250 educators. Descriptive statistics were used to analyze data on the educators’ responses about the extent to which they implemented the inclusive education policy. Statistical data revealed that the implementation of the policy was modest. Educators do not effectively use the screen resources such as the learner profile to screen barriers and the Support Needs Assessment 1 is not effectively used to identify and assess the barriers experienced by learners. As a result, support of learners was found to be inadequate. An independent-samples t-test revealed that there was statistically significant difference between the means of primary and secondary schools in the application of SIAS 2014 policy. This research recommends that the teacher training institutions should capacitate aspiring educators about inclusive education policies such as the SIAS 2014 policy rationale, principles, and how the policy is to be effectively implemented at schools.

Process Simulation of Oxy-Fuel Combustion for A 120 MW Coal-Fired Power Plant Using Aspen Plus
Authors: A.O Odeh , L.A Okpaire , E.A Oyedoh
Published: January 2022

Oxy-fuel Combustion is a technology with the potential of drastically reducing the amount of CO2 emission, it relies on the use of oxygen and recycled CO2 instead of air as the oxidant. This helps to reduce the amount of the CO2 and NOx emissions. This study focuses on the components of flue gas produced and their amounts for oxy-fuel combustion in a coal-fired power plant (CFPP) and also the boiler efficiency using the direct (input-output) method. The combustion process of pulverized coal in a 120MW power plant is studied using Aspen Plus 11. The amount of each component in flue gas in coal-fired processes with air or O2/ CO2 (using recycle of 20%, 40%, 60% and 80% of CO2) as oxidizer was obtained. From the process simulation, as the recycle % of CO2 was increased, the flame temperature, CO and NOx emissions were reduced. The simulation results of air combustion were compared with that of oxy-fuel combustion with 80% recycle and it was seen that the flame temperature dropped from 1894oC when air was used as oxidizer to 1679oC for oxy-fuel combustion with 80% recycle. Also, there was a reduction in the amount of NOx produced, but the SOx levels were constant for both combustion processes. The Gross Calorific Value (GCV) of the coal was calculated from its Proximate Analysis using Dulong’s formula and it was used to estimate the Boiler Efficiency using the Direct (Input-Output) method and a value of 83.6% was obtained.
Framing Land Governance Issues in Indigenous and Settler Media within Canada
Authors: Harding Robert , Ray Sterling
Published: January 2022

This comparative study examines how the framing of Indigenous land governance issues—such as resource extraction activities on Indigenous territory and treaty negotiation—in Indigenous media differs from that in corporate news. Methods of Critical Discourse Analysis were applied to 66 news texts published in 2018 in large corporate newspapers, such as the National Post, and small Indigenous news outlets, such as Eagle Feather News. Researchers found that Indigenous media connected land governance issues to contemporary issues, such as racism and control over child welfare, as well as historical colonialism and Indigenous-Settler relations, while corporate news generally excluded any discussion of these contextual factors. While the main news frame in the Indigenous press was Indigenous people were not consulted, the dominant frame in corporate news was Indigenous peoples have already been adequately consulted. Corporate news discourse valorized Indigenous traditional territory solely based on its presumed “economic value.” By contrast, Indigenous publications offered a counternarrative, one that positioned land and the rest of the natural environment as something that has absolute value, and as indivisible from all living things, including people.

Published: January 2022

Estudaram-se em 6 doentes com valvulopatias reumatismais, as variações da actividade enzimática no plasma, durante e apos a cirurgia cardíaca com circulação extra-corporal, para verificar a especificidade da isoenzima MB da creatinaquinase, comparando-a com a da CK. Estudaram-se também as variações da desidrogenase láctica no mesmo período. O protocolo de colheitas escolhido, procurava dissociar as variações enzimáticas correspondentes aos tempos anteriores a miocardiotomia, das relacionadas com a lesão cirúrgica das fibras miocárdicas. Os autores verificaram existir um paralelismo evidente entre as curvas referentes a CK total e a sua isoenzima MB. Esta última elevava-se mais tardiamente, apenas durante os tempos cardíacos da intervenção, atingia o máximo no final desta e voltava mais rapidamente aos valores iniciais. A CK-MB regressava aos valores basais no 3º dia do pós-operatório e a CK-total entre o 5.° e o 7º dia. Os autores concluem que a isoenzima CK-MB é um indicador fiel e pouco sujeito a erros para detecção precoce de sofrimento das fibras musculares cardíacas. Os valores da LDH sofreram variações mais irregulares, atribuíveis a interferência de diversos factores, mas pareceram de interesse na detecção de complicações durante o pós-operatório.
The use of echocardiography to determine left ventricular size. A simultaneous echocardiographic and angiocardiographic study.
Authors: Seabra-Gomes R , Rickards Anthony , Sutton Richard
Published: January 2022

Foi feito o estudo simultâneo das dimensões do ventrículo esquerdo por cineangiocardiografia e ecocardiografia em 15 doentes sem cardiopatia isquémica, durante o exame hemodinâmico de rotina. O feixe de ultrassons interceptou o eixo menor ventricular segundo ângulos variáveis (de -11° a +18°) na diástole e na sístole, e o eixo longitudinal de 28% a 64% do seu comprimento na diástole e de 15 % a 64 % na sístole. As dimensões ventriculares foram maiores quando medidas a partir dos angiogramas no mesmo plano do feixe de ultrassons, embora exista uma boa correlação entre as dimensões ecocardiográficas e angiocardiográficas. Também a fracção de ejecção determinada a partir dos volumes ventriculares obtidos angiograficamente, se correlaciona bem com a fracção de encurtamento obtida ecocardiograficamente. São discutidos os erros práticos envolvidos nas medições ecocardiográficas e conclui-se que a extrapolação dessas dimensões, para a determinação de volumes ventriculares, deve ser executada cautelosamente.

Os vasodilatadores no tratamento da insuficiência cardíaca crónica.
Authors: Luís A. Sales
Published: January 2022

As paIavras de precaução tornam-se assim justificadas, para o momento: 1. a utilização de vasodilatadores na insuficiência cardíaca só é justificável para situações especiais, como complemento e não substituição da chamada terapêutica clássica: 2. A selecção do fármaco deve ser condicionada pela faceta hemodinâmica registada, quanto possível em termos objectivos, exactos, através de pressões intracardíacas e intravasculares, e de valores de débitos e volumes sistólicos. 3. O tratamento deve ser controlado em regime de internamento na sua fase inicial, para avaliar das respostas. 4. Deve haver vigilância atenta e frequente da evolução e do aparecimento de efeitos colaterais. 5. Torna-se indispensável verificar, periodicamente, se persistem as condições hemodinâmicas que levaram a prescrição. Com estes condicionamentos, abrem-se assim perspectivas muito promissoras para os doentes em insuficiência cardíaca congestiva.

Authors: Santos A. Lema , Aleixo Ana M. , Landeiro Jorge , Luís A Sales
Published: January 2022

A amiodarona, electrofisiologicamente capaz de aumentar a duracao do potencial monofásico, foi utilizada para tratar 80 doentes com Fibrilhação auricular estável. Em 88 tratamentos, obtiveram-se 75 conversões a ritmo sinusal (86 %). Verificou-se uma taxa de reversão a fibrilhação baixa, pois de 44 doentes revistos ao fim de 1 ano, 32 persistiam em ritmo sinusal (72 %). Os insucessos terapêuticos foram relacionados com a existência de aurículas dilatadas. Dos efeitos acessorios verificados, reversíveis, foram destacadas as lesões corneanas, as alterações hormonais e as repercussões sobre a condução aurículo-ventricular e intraventricular. Comparando com os resultados obtidos com a cardioversão elétrica, conclui-se pela vantagem do fármaco, pela igual eficácia e inocuidade, e pela maior facilidade de realização da conversão química.

Authors: Ribeiro J. M. Carrilho , Lacerda Armando
Published: January 2022

A ultrassonografia utiliza os ultrassons para estudar órgãos e estruturas. Fundamenta-se na diferente reflexão que um feixe de ultrassons sofre ao atravessar os tecidos orgânicos e no tratamento eletrónico, que transforma o feixe reflectido em imagem. Os primeiros passos importantes no sentido de aproveitar os ultrassons para diagnóstico em Medicina deram-se nos anos 40, com as tentativas de obtenção de imagens cranianas por Dussik, o verdadeiro pai da ecografia. No entanto, só aos últimos 15 anos os progressos verificados impuseram e generalizaram o método. Através da ultrassonografia e possível definir formas, dimensões e estruturas de muitos órgãos. São suas principais indicações o diagnóstico de lesões que ocupam espaço e a destrinca entre lesões sólidas e líquidas. Para além da sua capacidade descriminativa, tem a particularidade de ser totalmente inócua para o doente e para o médico.

Symptomatological studies were carried out in two tomato growing areas in Daloa to estimate and identify the associated nematode populations. Symptoms were assessed by visual observation. The soil and root nematodes were extracted by Bermann's method and identified by observing morphological characteristics. The symptomatological study showed the presence of symptoms of plants wilting, yellowing of the leaves as well as galls on the nematodes characteristic roots. The results also highlighted diversity within the nematode population that colonizes tomato in Daloa with four genera of nematodes. The genera Tylenchus, Helicotylenchus, Partylenchus and Meloidogyne were identified. The presence of the genus Meloidogyne in all plots shows that it is responsible for the yellowing symptoms associated with root galls. These nematodes are known for their action on the formation of galls on the roots of the tomato.

A total of 18 bitches in the period in the period of six month diagnosed for transmissible venereal tumor in Teaching Veterinary Clinical Complex, Nagpur by per vaginal examination and vaginal cytology. These bitches were divided randomly into three groups, viz., Group I (Inj. Vincristine @ 0.025mg/kg slow IV in DNS and Injection Botropase 1ml IM for 1st week), Group II (Inj. Vincristine @ 0.025mg/kg slow IV in DNS and Tab. Amoxycillin and Potassium Clavinate for first 7 days orally) and Group III (treated with autohaemotherapy@10 ml whole blood IM) for once in week and continue for 5 week. At the time of treatment, liver and kidney function tests were performed. During the course of treatment significant variation was noted in Group I and II in BUN values while creatinine values changes significantly in all treatment groups. In case of SGPT only significant changes observed in Group I. Rest of the changes in serum prolife found to be non significant. Also from recovery point of view we noted that, it was faster in Group I and II compare than Group III. Side effects observed only in Group I and II. From the study we concluded that autohaemotherapy will be an alternate option for treatment of TVT in bitches who shows the excessive side effects of Vincristine Sulphate.

Infertility affects millions of people of reproductive age worldwide and has an impact on their families and communities. Infertility is a disease of male or female reproductive system defined by failure to achieve a pregnancy after 12 months or more of regular unprotected sexual intercourse. Infertility is treated by different fertility drugs, ovulation induction (OI), intrauterine insemination (IUI) and in-vitro fertilization (IVF). The aim of the study is to find out the significant difference in pregnancy rate with different OI protocols used for IUI. OI is the first line treatment given to infertile women. In OI, medications are given to women for egg development and for release of eggs. OI is monitored by follicular study by ultrasonography. Semen is collected from the male partner and processed with culture media to retrieve high motile sperms, which are injected into the uterus of the female. A prospective randomized study was performed among 1343 IUI cycles. OI is started on Day 2 or Day 3 of the menstrual cycle. OI protocol is grouped according to the fertility drugs used for stimulation. The fertility drugs used for the stimulation are Clomiphene Citrate, Letrozole, Recombinant Gonadotropins, Human menopausal Gonadotropins (HMG), Human chorionic Gonadotropin (HCG). Group A uses Clomiphene citrate and HCG, Group B uses Clome, recombinant Gonadotropins and HCG. Group C uses Clome, Human menopausal Gonadotropin and HCG; Group D uses Letrozole and HCG. Group E uses Letrozole recombinant Gonadotropin and HCG. Group F used Letrozole, Human menopausal Gonadotropin and HCG. Group G used recombinant Gonadotropin and HCG. Group H used Human menopausal Gonadotropin and HCG. Group I uses only HCG. Group J was a natural cycle monitoring without any medication and was used as a control. Pregnancy rates were calculated for different age groups with different protocols. The result shows that Group B had 13% pregnancy, Group C had 9%, Group D had 3%, Group E had 10%, Group G had 11%, Group G had 11%, Group H had 7%, Group I had 4%, and Group J had 8% of pregnancy rate. The statistical analysis shows there is no significant difference with different stimulation protocols used.

Published: January 2022

Rhizosphere, phylloplane and caulosphere is the region where a complex community of microbes, mainly bacteria and fungi are present. The microbe plant interaction in these regions can be beneficial, neutral, variable, or deleterious for plant growth. The bacteria that exert beneficial effects on plant development are termed plant growth promoting bacteria. To quantify the amount of phosphate solubilizing bacteria from rhizosphere, phylloplane and caulosphere of brinjal (Solanum melongena L.). Materials and methods: Brinjal (Solanum melongena L.) plants of different varieties were collected from seven locations around Bangalore viz., Hessaraghatta, Yelahanka, Kengeri, Madi vala, Hebbal, Tirumalapura and Attibele were also screened for the presence of phosphate solubilizing bacteria. Nitrogenase activity was estimated by acetylene reduction assay and analyzed by gas chromatography. The amount of nitrogen fixed brinjal bacterial isolate was quantified by micro Kjeldhal method. The amount of nitrogen fixed by the BBI was equivalent to 23.5 nm of C2H2 reduced/tube/hour. The amount of nitrogen fixed by the BBI showed a steady increase upto three days (75 nm of C2H2 reduced/tube/hour) after which there was a decline in the amount of nitrogen fixed by the microbe. Phosphate solubilization by the bacteria isolated from brinjal is highly beneficial to the crop, as it would always make more phosphate available to the crop. This phosphate solubilizing potential could be harnessed to reduce the input of inorganic fertilizers. For the first time the presence of phosphate solubilizing bacteria on the rhizosphere and endorhizosphere of brinjal (Solanum Melongena L.) cultivars was established.

Published: January 2022

Healthcare-associated infections (HCAIs) are a major concern and associated with noticeable morbidity and mortality. To combat this, the simple strategy is hand hygiene (HH). In a resource constraint settings one of the important reason for poor hand hygiene compliance is irregular supply of HH products. This study was done to assess the cost effectiveness and acceptability of WHO recommended locally made alcohol based hand rub. The study was carried out in 28 HCPs working in an IMCU. Samples for the assessment of the microbial hand contamination were collected by direct fingerprint of their dominant hand onto the blood agar plates at three different time point. Group A samples collected in random. Group B samples collected immediately after patient physical examination. Group C were group B representatives collected after cleaning their hands with locally made isopropyl alcohol based hand rub. No significant difference in colony count between the groups A and B was observed. On the other hand, there was a statistically significant difference in colony count between the groups B and C (P=0.05). It means that the rubbing of the hands using locally made WHO recommended hand sanitizer enabled to eradicate the bacterial flora remarkably from the hands of HCPs.

Phenotypic Stability Analysis for Seed Yield and its Associated Traits In advanced lines of Indian Mustard (Brassica juncea L. Czern and Coss)” was carried out to study the effects of different environments on seed yield and its associated traits, to estimate the magnitude of Genotype x Environment interaction and to find out the most stable and high yielding genotype among the selected lines of Indian mustard under different environments of different topography, soil texture and prevailing climatic conditions of Manipur. Fifteen genotypes were evaluated in 3 different locations (Andro, Iroisemba and Senapati) in RBD with 3 replications over two seasons viz; Rabi 2018-19 and 2019-20. The environment wise ANOVA revealed highly significant differences among all the genotypes studied for all the 11 characters of seed yield and its associated traits. The pooled ANOVA also indicated significant differences among the environments, genotypes as well as genotype by environment (GXE) interaction for all the traits. Genotype X Location interaction was observed as the main component for GXE interaction. Genotypes performed better in 2019-20 rabi season as compared to rabi 2018-19. Environment (E-5) i.e. Iroisemba, valley area was the best for expression of most of the characters studied. Stability Analysis using Eberhart and Russell indicated the significance of GXE (linear) for no. of siliqua/plant, no. of seeds/siliqua, siliqua length, no. of primary branches, no. of secondary branches, days to first flowering, days to 50% flowering, days to 80% maturity and 1000 seed weight except for plant height and seed yield per plot which shows the substantial amount of predictable G X E interaction for the expression of these characters in the selected genotypes. All the 15 genotypes were tested for 3 stability parameters, viz mean, bi and S2 di. The genotypes CAURMM-3, CAURMM-4, CAURM- 5, CAURM-4, PM- 25, CAURMM-1 and JM-1 were identified to be the high yielding and stable, hence they can be recommended for general cultivation under varied environments of Manipur. CAURM-1 CAURM-2, CAURM-3 had more stable characters although their yield was below the population mean, Therefore, proposed as promising genotypes for general cultivation under intensive input supply as they performed best in favourable environments, while NRCHB 101 found to be suitable for cultivation under poor environments.

The study and survey which was carried out to identify and assess diversity of plant species of sub tropical pine forest of Meghalaya was conducted during 2020-2021 at three different elevation stands located at 982 m (low-elevation stand), 1485 m (mid-elevation stand) and at 1816 m (high-elevation stand). Pinus kesiya was found to be the most dominant from all the three stand. A total of 34species of trees belonging to 19 families were recorded which consisted a total number of 857 individuals of trees, 14 species of shrubs belonging to 10 families recorded a total number of 866 individuals, and an overall occurrence of 20 species of herbaceous species belonging to 13 families recorded a total number of 670 individuals. Elaeagnus conferta was maximum for IVI in both high and mid elevation stand while Lantana camara showed maximum IVI in the low elevation. The herbaceous species diversity, richness and evenness indices was highest in high elevation and lowest in the low elevation, while herbaceous species of dominance showed a reverse trend. Tree and shrub species of the three elevation stand were quite similar in the mid and low elevation stand. The diversity richness of indigenous forest shows considerable variation in occurrence of species between different altitudes. Most of the species in the study area have medicinal value and socio-economic importance. Therefore, there is a need for necessary action towards sustainability of forest and conservation of species at large.
