The flowers and caryopses of Festuceae, Festucinae (sensu Pilger, 1954) have been morphologically studied. All the genera, which show non-festucoid features in respect to non-morphological characters, are also different from true Festuceae, Festucinae in such details of their morphology as lodicules, pistils, and caryopses. On the other hand, the festucoid genera are very closely related to one another as regards these organs. The systematic positions of the genera showing non-festucoid traits in non-morphological characters are being considered in connection with their characteristics of flowers and caryopses. The results clearly indicate that the conventional treatment of morphological characteristics, in which stress is laid on some macroscopic characters, such as inflorescences or the appearance of lemmas, is quite inadequate, and that great attention should be paid to the features of flowers and caryopses, as well as spikelets and other morphological characters. A new tribe Brylkinieae is proposed.

This research is an examination and a study on the influence of rewards on job satisfaction of lecturers at Shinas College of Technology (ShCT). In academic industry, rewards are one of the factors that affecting job satisfaction of the employees and this will lead to affect their performance in their jobs. So, when rewards are more the job satisfaction will be high and when rewards are less the job satisfaction will be less. On the other hand, the age will not affect the job satisfaction. Previous research reveals that Job satisfaction is very important to success the industry and the rewards are the main factors which affect job satisfaction. The main purpose of this study is to know the influence of rewards in job satisfaction among the lecturers in ShCT. Moreover, this research attempts to identify how much rewards affect the job satisfaction in ShCT.  For this study used two types of data which are: primary data and secondary data. The sources of primary data is the response from lecturers at ShCT. It is collected through structured questionnaire and distributed such to 60 respondents. Secondary data, collected from internet, books, journals, articles etc.

AbstractIn this article attempts are made to study one of the important topics that has been widely discussed in Islamic legal literature, namely al-tadawi bi al-muharramat (treatment with forbidden things), with special reference to al-khamr (intoxicating drink). In this regard, there are two different opinions of Muslim jurists regarding the use of intoxicating drink (al-khamr) for medical purposes. The majority of Muslim jurists are of the opinion that treatingdisease with forbidden things is unlawful. As such, they did not allow the use of intoxicating drink for any reason, including its use as a remedy, or to quench thirst, even if there are no other permissible fluids to drink. On the other hand, a few Muslim jurists did allow the use of an intoxicating drink as a remedy, or to quench thirst if no other permissible fluid is available.

Two species of tetraploid (2n = 28) and three varieties of hexaploid (2n = 42) wheat were crossed with A. glaucum (2n = 42), and A. elongatum (2n = 70), with an average crossing success of 18%. The seed obtained from tetraploid wheat × A. glaucum was slightly plumper and germinated better than that obtained from tetraploid wheat × A. elongatum. On the other hand, hexaploid wheat × A. elongatum gave decidedly plumper and better germinating seed than hexaploid × A. glaucum.Grown under greenhouse conditions the F1 hybrids proved to be self-sterile and perennial in habit, with hybrid vigor strongly marked. The hybrids were, in general, intermediate in morphological characters, but with somewhat more resemblance to Agropyron than to wheat. This dominance, whole or partial, was more noticeable in the A. elongatum than in the A. glaucum crosses. Dominance phenomena are discussed in relation to current theories.

Opening ParagraphIn 1971–2 I undertook research in part of the very densely populated farming zone around Kano city (often called the Kano close-settled zone) in order to compare it with a Hausa village, Batagarawa, some 100 miles further north in Katsina Emirate, where I had lived and worked in 1967. At Batagarawa farmland is not scarce and members of the community are free to establish farms on uncultivated (bush) land, some of which is no further than a mile or so from the village. For some 30 to 40 miles or more around Kano city, on the other hand, there is little or no uncultivated bush and farmers with insufficient land are obliged to buy or to ‘borrow’ (aro) farmland from others. My purpose was to compare and contrast the socio-economic organization and economic conditions of farmers in the two localities, with special reference, in so far as this variable could be isolated, to population density.

Marphysa simplex is a name that three species bear within the same genus, but each has a different authority and morphological characteristics. This homonymy condition leads to taxonomic confusion and the finite designation of name-bearing is imperative. The current study focuses on two species identified as M. simplex Crossland, 1903 and M. simplex Treadwell, 1922 and a third one, recently considered a secondary homonymy, M. simplex (Langerhans, 1884), is also assessed. The available type specimens were examined and re-described in detail using updated characters and the original descriptions. Marphysa simplex (Langerhans, 1884) is herein judged as an indeterminable species. Marphysa simplex Crossland, 1903 is confirmed as a junior synonym of M. teretiuscula (Schmarda, 1861a) because the differences are minimal. Moreover, M. teretiuscula has characteristics similar to Group B2 (Sanguinea-group; only compound spinigers), instead of the Teretiuscula-group (compound spinigers in the anterior region, subacicular limbate in all chaetigers). On the other hand, M. simplex Treadwell, 1922 is a junior primary homonym of Crossland’s species replaced by M. fijiensisnom. nov. with the chaetal arrangement similar to Group A (limbate chaetae only). In conclusion, the name M. simplex is now unacceptable. The hypothesis on species group only with limbate chaetae and the redescription on M. teretiuscula is also given.

La atracción migratoria (reciente y acumulada) es una construcción específica de la migración interna, la cual contiene dinámicas socioeconómicas y culturales, entre otras, desde los centros rurales o urbanos, con perspectivas territoriales y regionales. En México, el indicador de la atracción migratoria reciente muestra mejores condiciones y dinámicas de la economía desde hace siete años. Por su parte, Veracruz presenta desde hace una década un importante crecimiento demográfico y de inmigración interna, además de una significativa migración hacia entidades del norte. En este contexto, el objetivo del artículo es construir indicadores de atracción migratoria y reciente a nivel nacional y para el estado de Veracruz, que sirvan como base para futuras investigaciones que profundicen en las causas y factores de la migración interna, y expliquen las dinámicas entre un territorio y otro. The migratory attraction (recent and accumulated) is a specific construction of internal migration, which contains socio - economic and cultural dynamics, among others; from rural or urban centers, with territorial and regional perspectives. In Mexico, the indicator of recent migration attraction shows the best conditions and dynamics of the economy since seven years ago. On the other hand, Veracruz has had an important demographic and internal immigration growth since a decade, as well as an important migration towards northern entities. In this context, the objective of the article is to build indicators of mig ratory and recent attraction at the national level and for the state of Veracruz, which serve as a basis for future research that delves into the causes and factors of internal migration and explain the dynamics between one territory and another.


Ehrlich (1898) (1903) came to the conclusion that the toxin secreted by B. Diphtheriæ is neutralised by diphtheria antitoxin much as an acid is by a base. The course of the neutralisation seems to him to indicated the presence of several toxic substances and atoxic forms of the same substances in the toxic fluid which are successively neutralised by the gradual addition of antitoxin. After complete neutralisation of the various toxins, a substance—toxone—remains which has the property of causing diphtheritic paralysis, and also of neutralising antitoxin. Similar constitutions have been ascribed by Ehrlich and his pupils to other toxic fluids, and to the hæmolytic filtrates or lysins obtained from certain bacterial cultures. On the other hand, Arrhenius and Madsen (1902) (1904) concluded that the toxin-antitoxin reaction is quite analogus to the action of an acid on an alcohol, and that the chemical laws of mass action, which hold for the latter, apply equally well to the former. The chief reaction is considered to be a reversible one between two substances only, toxin and antitoxin, and when the system has reached equilibrium, a fraction of the toxin and also of the antitoxin remain free. The toxone effect they ascribe to a trace of free toxin. The numerical relations deduced are approximately in agreement with the experimental observations they have made on equilibria obtaining between toxins and antitoxins, and likewise between lysins and antilysins. Nernst (1904) has, however, pointed out that the laws of mass action are not applicable to these reactions.

The morphological characteristics of dauer juveniles were examined forBursaphelenchusxylophilus,B. firmaeandB. mucronatus kolymensis. Dauer juveniles ofB. xylophilusandB. firmaewere collected directly from their carrier insects,Monochamus alternatusandM. grandis, respectively.Bursaphelenchs m. kolymensisdauer juveniles were induced experimentally usingM. alternatuspupae. The dauer juveniles of these three species were distinguished according to their respective body shapes.Bursaphelenchus xylophiluswas relatively slender compared to the other species. The position of the excretory pore was anterior to the median bulb inB. firmae, overlapping with the median bulb inB. xylophilus, and posterior to, or overlapping with, the posterior part of the median bulb inB. m. kolymensis. The tail tip ofB. firmaewas conical, that ofB. xylophiluscontained a short projection, while inB. m. kolymensisthe tail tip was blunt with a thick mucron.

There have been four subspecies of hemlock dwarf mistletoe (Arceuthobium tsugense: Viscaceae) described by various investigators of this complex group of parasitic flowering plants: subsp. tsugense, subsp. amabilae, subsp. contortae, and subsp. mertensianae. As suggested by their subspecific epithets, these taxa differ in their host affinities; parasitizing different and the same hosts to varying degrees. Although these taxa also have morphological differences, their classifica-tion has been under debate for many years. Therefore, we compared the morphological characteristics of each subspecies using both univariate and multivariate statistical analyses in order to better assess their differences. Because some investigators have grouped hemlock dwarf mistletoe with western dwarf mistletoe (A. campylopodum), we also compared the subspecies of hemlock dwarf mistletoe with western dwarf mistletoe. Our morphometric analyses demonstrated that all of the subspecies are morphologically distinct from western dwarf mistletoe and that subsp. contortae is the most morphologically differentiated of the subspecies. Overlap in the morphological characters across two of the other three subspecies was evident; yet, subsp. amabilae and subsp. mertensianae were also consistently delimited using female and male plant morphologies. Statistical comparisons of female or male plants via standard and stepwise discriminant function analyses demonstrated that without consideration of host plant, female and male A. tsugense subsp. tsugense are morphologically similar to corresponding plants of subsp. amabilae and mertensianae but not subsp. contortae or A. campylopodum.

This Research Paper will coverthe concept of–whether women have equal shares over the coparcenary property or not & on the other hand it will also discuss the landmark judgment of Vineeta Sharma V/S Rakesh Sharma which has opened up a space for the women to have equal shares in the ancestral property of Hindu Undivided Family.Since the inception of the Hindu Succession Act, 1956 the provision for the division of property of Hindu Undivided Family was only limited to the sons but the amendment of 2005 made some of the special changes to the act, adding daughters as the equal shareholders to the coparcenary property and even this amendment providedthat,the daughter can be the Karta of the Hindu Undivided Family.With special reference to the case of Vineeta Sharma vs Rakesh Sharma this research note will provide in-depth analysis with conflicting case laws where it will be put forth whether the coparcenary property are the property of the sons or even the daughter can claim for equal shares over the Hindu Undivided Family property.
