Abstract. The geochemistry of biogenic carbonates has long been used as proxies to record changing seawater parameters. However, the effect of ocean acidification on seawater chemistry and organism physiology could impact isotopic signatures and how elements are incorporated into the shell. In this study, we investigated the geochemistry of three reservoirs important for biomineralization – seawater, the extrapallial fluid (EPF), and the shell – in two bivalve species, Crassostrea virginica and Arctica islandica. Additionally, we examined the effects of three ocean acidification conditions (ambient: 500 ppm CO2, moderate: 900 ppm CO2, and high: 2800 ppm CO2) on the geochemistry of the same three reservoirs for C. virginica. We present data on calcification rates, EPF pH, measured elemental ratios (Mg/Ca, B/Ca), and isotopic signatures (δ26Mg, δ11B). In both species, comparisons of seawater and EPF Mg/Ca and B/Ca, [Ca2+], and δ26Mg indicate that the EPF has a distinct composition that differs from seawater. Shell δ11B did not faithfully record seawater pH and δ11B-calculated pH values were consistently higher than pH measurements of the EPF with microelectrodes, indicating that the shell δ11B may reflect a localized environment within the entire EPF reservoir. In C. virginica, EPF Mg/Ca and B/Ca, as well as absolute concentrations of Mg, B, and [Ca2+], were all significantly affected by ocean acidification, indicating that OA affects the physiological pathways regulating or storing these ions, an observation that complicates their use as proxies. Reduction in EPF [Ca2+] may represent an additional mechanism underlying reduction in calcification in C. virginica in response to seawater acidification. The complexity of dynamics of EPF chemistry suggest boron proxies in these two mollusc species are not straightforwardly related to seawater pH, but ocean acidification does lead to both a decrease in microelectrode pH and boron-isotope-based pH, potentially showing applicability of boron isotopes in recording physiological changes. Collectively, our findings show that bivalves have high physiological control over the internal calcifying fluid, which presents a challenge to using boron isotopes for reconstructing seawater pH.

Abstract. Agricultural practices are responsible for a major source of ammonia (NH3) to the atmosphere which has implications for air quality, climate and ecosystems. Due to the intensification of food and feed production, ammonia emissions are expected to increase significantly by 2100 and would therefore affect atmospheric composition such as nitrate (NO−3 ) or sulfate (SO2−4 ) particle formation and surface deposition feedback. Chemistry-climate models which integrate the key atmospheric physicochemical processes along with the ammonia cycle represent a useful tool to investigate present-day and also future ammonia pathways and their impact on the global scale. Ammonia sources are, however, challenging to quantify because of their dependencies on environmental variables and agricultural practices and represent a crucial input for chemistry-climate models. In this study, we use the chemistry-climate model LMDZ-INCA with agricultural and natural soil ammonia emissions from a global land surface model (ORCHIDEE with the integrated CAMEO module) for the present-day and 2090–2100 period under different socio-economic pathways. We show that this new set of emissions improves the spatial and temporal atmospheric ammonia representations in Africa, Latin America, and the US compared to the static reference inventory (CEDS). Higher ammonia emissions in Africa, as simulated by CAMEO compared to other studies, reflect enhanced present-day reduced nitrogen (NHx) deposition flux. This partially contributes to the 20 % higher NHx deposition in our results compared to other modeling studies at the global scale. Future CAMEO emissions lead to an overall increase of the global NH3 burden ranging from 37 % to 70 % while NO−3 burden increases by 38 %–50 % depending on the scenario even when global NOx emissions decrease. When considering the most divergent scenarios (SSP5-8.5 and SSP4-3.4) for agricultural ammonia emissions the direct radiative forcing resulting from secondary inorganic aerosol changes ranges from -114 to -160 mW.m−2. By combining a high level of NH3 emissions with decreased or contrasted future sulfate and nitrate emissions, the nitrate radiative effect can either overshoot (net total sulfate and nitrate effect of -200 mW.m−2) or be offset by the sulfate effect (net total sulfate and nitrate effect of +180 mW.m−2). We also show that future oxidation of NH3 could lead to an increase in N2O emissions of 0.43 to 2.10 Tg(N2O)yr−1 compared to the present-day levels. Our results suggest that accounting for nitrate aerosol precursor emission levels but also for the ammonia oxidation pathway in future studies is particularly important to understand how ammonia will affect climate, air quality, and nitrogen deposition.
Brief Communication: Representation of heat conduction into the ice in marine ice shelf melt modeling
Authors: Wiskandt Jonathan , Jourdain Nicolas
Published: August 2024

Abstract. Basal melt of marine terminating glaciers is a key uncertainty in predicting the future climate and the evolution of the Antarctic and Greenland ice sheets. Regional ocean circulation models use parameterizations that depend on the available heat to parameterize basal melt. The heat budget at the ice–ocean interface includes turbulent heat flux from the ocean below, latent heat for phase transition, and heat conduction into the ice. Here we review the estimation of heat conduction into the ice, which has been treated in various ways in modelling studies so far. We show that the formulation of Holland and Jenkins (1999) best captures the variety of temperature profiles measured in boreholes. Accounting for heat conduction into the ice reduces melt rates by up to 28 %.
A conservative resource use strategy in agricultural grasslands counteracts lower productivity and water use efficiency under drought conditions

Published: August 2024

Abstract. Grassland response to changes in water availability is closely tied to the traits of the plant community which determine plant water uptake and resource use. Plants can adopt either moderate and efficient (conservative) or rapid and demanding (acquisitive) resource use strategies. These strategies combined with the plant interactions with microbes, such as arbuscular mycorrhiza fungi (AMF), determine the grassland productivity and efficiency. This study aims to compare the drought response of two agricultural grasslands that differ in their resource use strategies. In an experimental garden 12 small-scale lysimeters were installed with two different agricultural grassland types (conservative and acquisitive) and two different irrigation levels (wet and drought). We measured water fluxes, above- and belowground phytomass productivity and AMF spore productivity in these two grassland types throughout a drought of 64 days. Despite differing resource use strategies, both grassland types exhibited similar reductions in evapotranspiration and aboveground phytomass under drought. However, the conservative grassland showed higher water use efficiency (WUE) when considering only aboveground phytomass, and a less pronounced compositional shift towards greater grass phytomass. Furthermore, in acquisitive grasslands the root:shoot ratio of grasses and AMF spores abundance in the soil were greatly reduced than in conservative grasslands. We also identified differences in legume productivity, rooting system, and AMF spores community composition as key factors influencing WUE. In a changing climate with greater frequency and severity of droughts in the European Alps, opting for grassland mixtures with more species with conservative characteristics should be considered, as they i) reach the productivity of acquisitive grassland even under wetter conditions and ii) show higher efficiency and longer vitality under drought conditions.

Abstract. Sea ice forms a thin but horizontally extensive boundary between the ocean and the atmosphere, with a complex crust-like dynamics characterized by intermittent sea ice deformations. The heterogeneity and localisation of these sea ice deformations are important characteristics of the sea ice cover that can be used to evaluate the performance of dynamical sea-ice models against observations across multiple spatial and temporal scales. Here, we present a new pan-Arctic sea-ice deformation and rotation rates (SIDRR) dataset derived from the RADARSAT Constellation Mission (RCM) and Sentinel-1 (S1) synthetic aperture radar (SAR) imagery from 01 September 2017 to 31 August 2023. The SIDRR estimates are derived from contour integrals of triangulated ice motion data, obtained from the Environment and Climate Change Canada automated sea ice tracking system (ECCC-ASITS). The SIDRR dataset is not regularised, and consist in stacked data from multiple SAR images computed on a range of temporal (0.5–6 days) and spatial (4–10 km) scales. It covers the entire Arctic Ocean and all peripheral seas except the Okhotsk Sea. Uncertainties associated with the propagation of tracking errors on the deformation values are included. We show that rectangular patterns of deformation features are visible when the sampled deformation rates are lower than the propagation error. This limits the meaningful information the can be extracted in areas with low SIDRR values, but allows for the characterisation of SIDRR in Linear Kinematic Features. The spatial coverage and range of resolutions of the SIDRR dataset provides an interesting opportunity to investigate regional and seasonal variability of sea-ice deformation statistics across scales, and can be used to determine metrics for model evaluation.

У статті розкрито питання правотворчої діяльності Верховної Ради України. Відзначено, що за понад 30-річний період незалежності в Україні так і не було вироблено єдиного підходу до правотворчої діяльності органів публічної влади, і лише Верховна Рада України ІХ скликання у непростих і, навіть, екстремальних умовах повномасштабної війни прийняла базовий законодавчий акт у сфері правотворчості. Наголошено на особливостях роботи Парламенту у період дії правового режиму воєнного стану, а також його результативності у сфері законодавчої діяльності. Відзначено важливість у період дії воєнного стану парламентської дипломатії та міжпарламентського співробітництва. Охарактеризовано специфіку оновлення системи законодавства, її «очищення» від радянського символізму. Статистичні дані щодо показників діяльності Верховної Ради України наведено станом на середину квітня 2024 року. Окрему увагу приділено Закону України «Про правотворчу діяльність», який містить низку новел і прогресивних положень, спрямованих на забезпечення участі громадянського суспільства у правотворчій діяльності та підвищення якості законодавства України, посилення координації роботи між Верховною Радою України та Кабінетом Міністрів України. Цьому сприятиме запровадження: аналітичних, прогнозних та програмних документів публічної політики для планування правотворчої діяльності; оцінки впливу як обов’язкового етапу розроблення проекту нормативно-правового акта; публічних консультацій із метою реалізації принципів відкритості та прозорості правотворчої діяльності тощо; ведення Міністерством юстиції України Єдиного державного реєстру нормативно-правових актів. Крім того, йдеться про: плановість діяльності Парламенту; здійснення правового моніторингу як запоруки реалізації контрольної функції Верховної Ради України; оптимізацію інституційної спроможності Парламенту. Шляхи подальшого удосконалення правотворчої діяльності Парламенту вбачаються, зокрема, у: здійсненні рекодифікації та декодифікації національного законодавства, що призведе до підвищення його якості у кращих європейських традиціях; побудові моделі покрокового алгоритму дій суб’єктів правотворчої діяльності на усіх етапах її здійснення; створенні єдиної інформаційної бази даних із питань адаптації законодавства України до положень права ЄС (acquis ЄС); запровадженні Єдиного реєстру правотворчих пропозицій (ініціатив, ідей); активному використанні ІТ-технологій у правотворчій діяльності; застосуванні аналізу довгострокових пріоритетів розвитку законодавства при плануванні Парламентом своєї роботи.
ІНКОРПОРАЦІЯ ЯК ФОРМА УПОРЯДКУВАННЯ ЧИННОГО ЗАКОНОДАВСТВА УКРАЇНИ

Published: August 2024

У статті розглядаються загальнотеоретичні проблеми інкорпорації законодавства. На основі аналізу наукових підходів, дається авторське визначення інкорпорації законодавства як однієї з форм систематизації, якій властиве зовнішнє упорядкування нормативно-правових актів шляхом їх об’єднання у збірники за певними критеріями та правилами без зміни їхнього чинного тексту. У статті зазначається, що інкорпорація є найменш складною формою систематизації, водночас вона важлива як її базовий, початковий елемент, який має тісні зв’язки з іншими формами систематизації. Зокрема, інкорпорація за предметом регулювання лежить в основі консолідованих нормативно-правових актів. Завдяки науково-теоретичній діяльності та її результатам свій процес розпочинає кодифікація. Таким чином, інкорпорація є приводом для початку активної діяльності щодо зміни і вдосконалення законодавства. Саме інкорпорація дозволяє зрозуміти, який його сучасний стан. За результатами інкорпорації можливо зробити висновок про недоліки та позитивні риси такого законодавства та надалі вдосконалювати його. Робиться висновок, що інкорпорація законодавства повинна проводитись відповідно до певних критеріїв та правил. У свою чергу, це дозволить відрізняти інкорпорацію від інших форм систематизації, здійснювати роботу щодо оформлення інкорпоративного збірника без застосування елементів консолідації або ж кодифікації.
A tensão entre constitucionalismo e democracia: o desafio da estabilidade constitucional no pluralismo democrático
Authors: Argenta Zaneti Graziela , de Castro Coura Alexandre
Published: August 2024

This article analyzes, from a hypothetical-deductive methodology, through the qualitative approach method, the tension between constitutionalism and democracy based on the search for stability throughout the history of constitutionalism, from the ancients (Greeks and Romans), in which consensus meant the search for the uniqueness of the social body and the detachment of individual interests, then in modern constitutionalism through the search for the rational consensus of citizens. And finally, in today’s plural democratic societies, the paradox between the logic of consensus, of identity brought by democracy and the logic of difference, of dissent between antagonistic, contradictory and yet reasonable conceptions brought by pluralism, makes the search for stability even more challenging. How to reconcile this permanent tension between these two logics and still be able to order, in an integral way, ideals and values in a democratic regime that can advance from generation to generation? What can be concluded is the real consensus that implies a truly democratic and fair system and that does not extinguish the democratic engine represented by dissent makes stability a still utopian ideal, especially if we understand constitutionalism as a project and democracy as an open and unfinished process.
Critérios para a delimitação da proteção jurídica da imagem dos agentes políticos/servidores públicos em face da liberdade de expressão/imprensa: Reflexão à luz do caso New York Times Co. v. Sullivan, 376 U.S. 254 (1964)

Through exploratory qualitative research, monographic procedure, inductive approach, the general objective is to analyze the ratio decidendi in the preceding New York Times Co. v. Sullivan, 376 US 254 (1964), with the aim of solving the problem about which criteria should be used in solving the real antinomy between the personality rights of a political agent or public servant on the one hand and freedom of expression / press on the other. With a focus on this research problem, it was assumed that due to the constitutional similarity between the compared systems, it would be possible to apply, in Brazilian law, the legal rules adopted by the American Supreme Court. As a result, based on the sources adopted, the hypothesis initially adopted can be confirmed, as it was found that the criteria used by the American Supreme Court in this paradigmatic precedent are compatible with the Brazilian constitutional system and offer an adequate criterion for the solution of this antinomy, since at the same time they guarantee the right to participation democracy through access to information as a rule, establish exceptions through the doctrine of the actual malice that is shown to balance the interests at stake, preventing the dissemination of information known to be false, or whose verification of veracity has been neglected by the journalist / broadcaster; as well as that defamatory information that relates to the strictly personal / intimate sphere of the public person’s life, since these cannot be considered covered by the “public interest”.

This research focused on a hydrothermal dike complex associated with the ~3.43-billion-year-old Strelley Pool Formation, which is renowned for exceptional preservation of some of Earth’s first shallow water marine environments and microbial ecosystems. Novel and conventional geochemical approaches were used to interpret the origin of carbonaceous material preserved in these ancient ecosystems which has historically been highly debated. Understanding how this information is preserved in the geological record is important not only for understanding the evolution of life on our planet, but also when looking for life on other planets such as Mars.

Visitor satisfaction greatly influences the development of the tourism industry, the development of the tourism industry in a region will give birth to other supporting businesses. The Samudera Pasai Islamic Museum is one of the cultural-based tourist attractions that displays tourist attractions in the form of fine art, historical relics and customs. The Samudera Pasai Islamic Museum is located in North Aceh Regency, Aceh Province. In 2023, the average number of museum visitors was 1,050 people and there was a significant decrease in visitors in September 2023. The purpose of this study was to determine visitor satisfaction with the quality of service provided by the management of the Samudera Pasai Islamic Museum. The method used in this study is the Service Quality (Servqual) method. Servqual is a method used to identify the level or quality of visitor satisfaction with the services provided by a service industry through five dimensions, namely tangibles (physical evidence), responsiveness, reliability, empathy and assurance by analyzing the gap between the value of perception and the value of visitor expectations. The results of the study showed that in the tangibles dimension, the gap value was obtained at -0.50, the responsiveness dimension obtained a gap value of -0.43, the reliability dimension obtained a gap value of -0.32, the assurance dimension obtained a gap value of -0.26 and the empathy dimension obtained a gap value of -0.34. These results indicate that the satisfaction of visitors to the Samudera Pasai Museum has not been achieved, so service improvements are needed

Despite the passage of 60 years, Germany remains one of the most preferred countries for Turkish migration. The demographic structure of migrants has changed, with educated and professional individuals now migrating with their families. Family migration brings along numerous challenges, one of the most significant being the ability of these families' children to learn and speak Turkish proficiently. This issue is particularly challenging for children born in Germany, as nearly all of them speak Turkish with an accent. The development of students' Turkish language skills depends on three main factors: Turkish learned at home, Turkish lessons received at school, and Turkish acquired in social life. This study investigates the impact of Turkish lessons on the Turkish language proficiency of these two groups of students. Within the scope of the research, a survey was conducted with 81 students of Turkish origin in grades 9-12 at Werner Heisenberg Realschule and Ferdinand Franz Wallraf Gymnasium, located at the Köln Schulzentrum Buchheim. It was found that while attending Turkish classes had a positive effect on students' Turkish proficiency, this contribution was significantly below the expected level. Various activities were suggested to improve the Turkish language skills of young people growing up in Germany. Keywords: Mother tongue Turkish, Turkish children in Germany, Turkish language teaching, migration.

Published: August 2024

The Stroop test, created by John Ridley Stroop in 1935, is one of the most famous assessments of cognitive abilities related to inhibition and attention (Stroop, 1935). In this test, the participants must identify the color of the ink used to print words as rapidly as possible, irrespective of the content of the words. Based on the findings from previous studies, the administration of caffeine or caffeine and taurine may positively impact cognitive processes. It may improve cognitive control, reduce interference effects, and enhance task performance, such as the Stroop test. The present study investigates how caffeine and taurine affect cognitive processes, particularly selective attention. The independent variable (IV) is the consumption or non-consumption of one of the stimulants (caffeine or taurine), while the dependent variable (DV) is the time taken to complete the Stroop test. One-way ANOVA was used to compare the mean time to complete the Stroop test between the three groups (control, caffeine, and taurine). 60 participants took part in this experiment and completed the Stroop test according to a sequence allocation method, randomly assigning them to one of the three groups based on the independent variable level (IV) they were given (caffeine, taurine, or control[decaf]). This procedure ensured that the study was conducted standardized and ethically and that the data collected were valid and reliable. No statistically significant results were detected in the analysis F(2,57)=0.801, p=0.454. There was no post-hoc test, as there was no statistically significant difference.

Estimation of the rate of non-ST-segment elevation myocardial infarction with non-obstructive coronary arteries (NSTE-MINOCA) and comparative analysis of clinical and management data with non-ST-segment elevation myocardial infarction with obstructive coronary arteries (NSTEMI-CAD). Material and methods: 494 patients diagnosed with NSTEMI were included in the study. The patients were divided into 2 research groups according to the presence of obstruction in the coronary arteries: group I - 35 patients with MINOCA and group II - 459 MI-CAD. Results: The MINOCA rate in the NSTEMI group was 7.08%. The risk factors: smoking, diabetes mellitus and hypertension was higher in the MI-CAD vs. MINOCA group. The concentrations of myocardial necrosis markers was higher in MI-CAD vs MINOCA: troponin - 8.58±0.89 vs 2.8±1.3, CK-MB 20.7±1.78 vs 13.97±2.6 ng/L, p<0.05 and high-sensitivity troponin - 767.4 vs 8248 ng/L, p<0.001. Patients with MINOCA had higher levels of C-reactive protein (CRP (36.62±16.27) vs MI-CAD (22.16±2.39), p<0.05. Regarding the treatment, the study highlighted that patients with MINOCA used less the double antiplatelet therapy (28.6 vs 89.2%), statins (45.7 vs 83.1%) and ACEI/BRA (90.4 vs 57.1%) than MI-CAD patients (p<0.001). Conclusions: The NSTE- MINOCA rate was 7,08%. MINOCA patients have a lower rate of risk factors. In MINOCA there are lower concentrations of myocardial necrosis markers and increased values of inflammatory markers compared to MI-CAD.

Published: August 2024

Systolic anterior motion (SAM) of the mitral valve (MV) can be a life-threatening condition. The SAM can result in severe left ventricular outflow tract obstruction and/or mitral regurgitation and is associated with up to 20% risk of sudden death (which is substantially lower in hypertrophic cardiomyopathy (HCM)).The mechanisms of SAM are complex and depend on the functional status of the ventricle. The SAM can occur in all cases, but is typically observed in patients with HCM or following MV repair.Echocardiography (2D, 3D and stress) has a central diagnostic role as the application of echocardiographic SAM predictors allows the incorporation of prevention techniques during surgery and post-operative SAM assessment.MRI (magnetic resonance imaging) has a special role in understanding the dynamic nature of SAM, especially in anatomically atypical hearts (including HCM).This article describes what the clinician needs to know about SAM ranging from pathophysiological mechanisms and imaging modalities to conservative (medical) and surgical approaches and their respective outcomes.A stepwise approach consisting of medical therapy, followed by aggressive volume loading and beta-adrenoreceptor blockers. Surgery is the final option. The correct choice of surgical technique requires an understanding of the anatomical substrate of SAM.

The study sought to identify the diagnostic significance of thromboelastography in 44 adult patients with acute superficial thrombophlebitis of lower limbs, diagnosed by duplex scanning. The distribution of the thrombotic process was described according to the Verrel-Steckmeier classification, with types II and III defined as «near the junction thrombosis». The research results testify to the fact that the intensification of the hemostasis process in patients with varicose vein thrombophlebitis has a predominantly structural character, due to the increased density of the formed clot. Patients with acute superficial thrombophlebitis exhibit a hypercoagulable status especially when the thrombotic masses are located near the sapheno-femoral/popliteal junction.

Abujhmadiya A Primitive Tribe: Their Livelihood
Authors: Kumar Barman Parivesh
Published: August 2024

The Indian society is home to various species. There are about 500 tribal groups and their sub-tribal groups in India, who live in remote areas of the country, forests and mountains. With time, other societies and cultures kept getting incorporated. Despite this, most of the tribal communities were successful in preserving their cultural heritage. However, in some tribal communities, the culture of other Indian societies definitely seems to have disappeared, which is a factor in the change in their traditional culture. The study of tribes in India was started by British administrators, missionaries and travellers individually or collectively to know and understand their culture. Research work on tribes started in India after the establishment of the Asiatic Society of Bengal (1974). Sir William Jones (1974) highlighted the importance of tribal chapters in “Nature and Man”. Generally, the general public knows them as Adivasis, Vanvasis, Primitive Tribes, Janjati, Van Jati. In the Indian Constitution, special provisions have been made with the objective of bringing them at par with the main society by naming them as Scheduled Tribes.

किसी भी देष व प्रांत के क्षेत्र के सम्पूर्ण विकास के लिये प्रषासन अत्यंत महत्वपूर्ण एवं आवष्यक अंग होता है। प्राचीन छत्तीसगढ़ में प्रषासनिक व्यवस्था की जो परिपाटी थी वह प्रायः कल्चुरि काल में विद्यमान थीं। छत्तीसगढ़ में लम्बे समय तक कल्चुरि राजवंष की अधिसत्ता रही है। इस राजवंष ने 11वीं शताब्दी से लेकर 18वीं शताब्दी मध्यान्त तक शासन किया था। दक्षिण कोसल के कल्चुरि, चेदि कल्चुरियों के वंषज थे, जिनकी राजधानी पुरानी शहर त्रिपुरी थी। इन कल्चुरियों ने छत्तीसगढ़ के इतिहास में एक नए काल की शुरूआत की है। लक्ष्मण राज ने त्रिपुरी से अपने पुत्र कलिंगराज को भेजा। कलिंगराज ने न केवल तुम्माण को अपने अधिकार में किया वरन अपने बाहुबल से दक्षिण कोसल का जनपद भी जीत लिया। उसने तुम्माण को अपनी राजधानी बनाया और दक्षिण कोसल में कल्चुरियों की वास्ताविक सत्ता की स्थापना की एवं नये सिरे से कल्चुरि राज्य की नींव 1000 ई. में डालकर अपनी शक्ति में वृद्धि कर ली। कुछ समय बाद कल्चुरि राज्य रतनपुर और रायपुर दो भागों में विभाजित हो गया। रतनपुर में कल्चुरि शासन 1741 ई. तक रहा। रायपुर में इनकी एक शाखा आई जिसे लहुरी अर्थात कनिष्ठ शाखा भी कहते हैं। कल्चुरि कालीन छत्तीसगढ़ का समाज श्रम विभाजन के आधार पर बंटा हुआ था। उसके अधिकार और कर्तव्य बंटे हुए थे। प्राचीन छत्तीसगढ़ में वर्ण व्यवस्था अपना स्थान प्राप्त कर चुके थे किंतु कट्टरता का अभाव था। छत्तीसगढ़ के कल्चुरि नरेष धर्म परायण थे और जनहित के कार्यों में रूचि रखते थे। इन्होंने अपने शासनकाल में शैव, वैष्णव, शाक्त, जैन, बौद्ध धर्माें को संरक्षण ही नहीं दिया अपितु उन्हें पुष्पित व पल्लवित भी किया। हिंदू समाज का स्वरूप संकुचित न होकर व्यापक था। यही कारण है कि शक, कुषाण, गुर्जर आदि विदेषी जातियों को हिंदू समाज में समाहित कर लिया गया।
