Long Term Observation Of The Grassland Vegetation Used Intensively Or Extensively And Ecologically, H.-D. Matthes, J. Matthes, W. Jentsch, V. Pastushenko

IGC Proceedings (1977-2023)

The aim of the present paper was to study alterations of the grassland flora from 55 plots following a more extensive management under long term observation within 6 years. Extensification of grassland use leads to an increase of the numbers of plant species by 32%, “Red-list-species” included. The moisture number of the soils slightly increased and the reaction and nitrogen numbers decreased. Results are presented for different vegetation units.

Influence Of Extensive Management On Botanical Composition Of Permanent Meadow Sward, K. Mlynarczyk, E. Korona, E. Marks

IGC Proceedings (1977-2023)

The aim of undertaken investigations was to find the possibilities of grassland management with special respect to the biodiversity and the landscape conservation. Changes in botanical composition of the meadow sward against a background of different mowing utilization were examined on the semi-natural meadows situated on the peat-mursh soil in Masurian Landscape Park (north-east Poland). The areas mown with biennial pause and completely turned off from uses followed gradual simplifying of species composition and increasing of bog species participation. Results show on advisability of passing one harvest each year or with one-year pauses.

Vegetation Changes In Sown Grassland In The Uk After Nine Years Of Extensive Grazing Management, C. A. Marriott, G. T. Barthram

IGC Proceedings (1977-2023)

The effect of extensive grazing management with sheep on vegetation change in sown pastures (initially containing Lolium perenne and Trifolium repens) in the uplands of Scotland was investigated from 1990-1999. One treatment was representative of current more intensive management systems; it was fertilized, and maintained at a sward surface height of 4 cm. Two treatments were unfertilized and were maintained at sward surface heights of 4 cm or 8 cm; the ewe numbers carried on these treatments averaged 74% and 44%, respectively, of those on the fertilized treatment. In all treatments the sheep were Scottish Blackface ewes. Their single …

The Illegally Traded Elephant In The Room: Species Terrorism & Combating Illegal Wildlife Trade, Áine Dillon

Pace International Law Review

The illegal wildlife trade has been a dilemma for decades

and remains prevalent globally – international intervention is

required now. While most countries participate in the Convention

on International Trade in Endangered Species of Wild

Fauna and Flora (“CITES”), not all countries have the same approaches

to combating the illegal wildlife trade. Unique approaches

can be beneficial because each illegally traded species

requires a different response, and countries with limited resources

can also participate. However, the lack of a unified response

hinders the global fight against the illegal wildlife trade.

While traditional methods to combat crime, such as passing

laws, …

Corporate Wealth Over Public Health? Assessing The Resilience Of Developing Countries' Covid-19 Responses Against Investment Claims And The Implications For Future Public Health Crises, Tim Hagemann

Pace International Law Review

In the wake of the Covid-19 pandemic, states around the world swiftly enacted a multitude of far-reaching emergency responses to contain the viruses’ spread and to cope with the economic repercussions of the ensuing crisis. However, these measures detrimentally impacted the operating conditions of many businesses or, at the least, decreased their profitability. As this inevitably affected foreign investments, investors could be tempted to invoke “Investor State Dispute Settlement” (“ISDS”) clauses in International Investment Agreements (IIAs) to initiate proceedings before arbitral tribunals and seek compensation for loss of profit caused by states’ Covid-19 responses. Due to the specific circumstances in …

Overhaul Of The Sdt Provisions In The Wto: Separating The Eligible From The Ineligible, Md. Rizwanul Islam

Pace International Law Review

The special and differential treatment (“SDT”) provisions have been a recurring feature in the agreements of the World Trade Organization (“WTO”) treaties. However, most analysts would probably agree that the many SDT provisions have been more aspirational than operational. Hence, there is little surprise that even a selective review of the WTO jurisprudence would demonstrate that the SDT provisions have, in most cases, not done enough for their intended beneficiaries. This paper will analyze the limitations of the SDT provisions with reference to the relevant WTO jurisprudence. It will seek to explore two potential avenues of endeavoring to make the …

A Poisson-Akash Inrar(1) Model For Over Dispersed Count Time Series, Emmanuel W. Okereke, Sunday N. Gideon

BAU Journal - Science and Technology

In this paper, a Poisson-Akash INAR(1) model was proposed in order to improve on the modelling of overdispersed stationary count time series. The estimators of the parameters of the model were derived using the Yule-Walker (YW) method and the conditional least squares (CLS) method. An expression for the conditional log-likelihood and the r-step ahead forecast were obtained for the model. Three overdispersed nonseasonal stationary count time series were modelled to illustrate the applicability of the proposed model as well as its capacity to outperform the competing INAR (1) models in modelling overdispersed stationary count time series and the result showed …

Walking Diagonally: A Simple Proof Of Countability Of The Set Of All Finite Subsets Of Naturals, Miroslav Kures

BAU Journal - Science and Technology

The countability of the set of finite subsets of natural numbers is derived. In addition to the derivation itself, the use of diagonal method is illustratively presented; thinking about infinite sets relate to the name of Georg Ferdinand Ludwig Philipp Cantor, the creator of set theory, which has become a fundamental theory in mathematics. The proof of the claim is original, although the theorem is an analogy with the famous theorem about the countability of rational numbers. A certain insight into the subsets of natural numbers is given. Anyway, the technique could be considered already at high school level as …

The Inhibition Activity Of Tert-Butylhydroquinone Towards Corrosion Of Aluminum, Copper And Stainless Steel In Biodiesel Blend B20 Alternative Fuel, Chaza Joumaa, Ibtissam Saad, Ghassan Younes

BAU Journal - Science and Technology

Tert-butylhydroquinone (TBHQ) has been investigated as corrosion inhibitor for aluminum; copper and stainless steel in biodiesel blend B20 by using electrochemical impedance spectroscopy (EIS) method. The results showed that the inhibition efficiency increases with an increase in the concentration of TBHQ but decreases with increasing temperature from 30℃ to 60℃. A maximum inhibition efficiency of about 61.52% for aluminum was recorded for THBQ in biodiesel blend B20 at temperature 30℃ and at a concentration of 4x10^-6 M which is the lowest concentration used compared to the concentrations of TBHQ used for the other metals (copper and stainless steel). Theoretical …
