Three new examples of 4-dimensional irreducible symplectic V-manifolds are constructed. Two of them are relative compactified Prymians of a family of genus-3 curves with involution, and the third one is obtained from a Prymian by Mukai's flop. They have the same singularities as two of Fujiki's examples, namely, 28 isolated singular points analytically equivalent to the Veronese cone of degree 8, but a different Euler number. The family of curves used in this construction forms a linear system on a K3 surface with involution. The structure morphism of both Prymians to the base of the family is a Lagrangian fibration in abelian surfaces with polarization of type (1,2). No example of such fibration is known on nonsingular irreducible symplectic varieties.

Zakat is an important form of religiously mandated charity under Islam. It is the third pillar of Islam. The giving of Zakat is important for Muslims, as this leads to purification of their wealth from all sins. This paper examines the role of Zakat as an instrument of social justice and poverty eradication in society. Each Muslim calculates his or her own Zakat individually. Generally, this involves the payment each year of two and a half percent of one's capital, after the needs of the family have been met. One can donate additional amount as an act of voluntary charity but Zakat is fundamental to every Muslim. Zakat is the Islamic contribution to social justice: those who have to give charity share the benefit of their prosperity to those who have fallen short. This is the Islamic approach to remove greed and envy and to purify one's soul based on good intentions. This is the institution of Zakat in Islam. The institution of Zakat serves to eradicate poverty in the community and uphold the light of Islam. Allah says “whatever is paid as Zakat for the sake of Allah shall be rewarded in manifolds”.

Background: Investigation of rare bleeding disorders in Latin-America. Objective: The report of a new case of FX deficiency due to a compound heterozygosis. Methods: Accepted clotting procedures were used. Sequencing of DNA was carried out by means of Applied Biosystems Instruments. Results: A compound heterozygote due to the association of a new mutation (Gla72Asp) with an already known mutation (Gly154Arg) of the FX gene is reported. The proposita is a 38 year old female who had a moderate bleeding tendency (menorrhagia, epistaxis, easy bruising). The proposita has never received substitution therapy but in the occasion of a uterine biopsy. The mother was asymptomatic but was a heterozygote for the new mutation. The father was asymptomatic but had deserted the family and could not be investigated. After this abandonment the mother of the proposita re-married with an asymptomatic man and she gave birth to a son who was asymptomatic but was also heterozygous for the new mutation (Gla72Asp). As a consequence it has to be assumed that the first husband of the mother of the proposita was heterozygous for the known mutation (Gly154Arg). Conclusion: This is the third case of a new mutation in the FX gene reported, during the past few years, in Argentina.

Between the third and first centuries BCE, a tomb near the Via Appia not only served as a funerary monument for the Scipiones but was also believed to have once contained the statue of a man from outside the family: Quintus Ennius. This chapter considers how Ennius’ poetry and portrait contributed to the circulation of political prestige. Linking the story of his statue to a later image of the poet in Varro’s De poetis, it argues that Varro’s collection of author portraits and the practice of erecting busts of authors in libraries are best seen as a form of entombment—situating the poet’s imago alongside those of his literary forebears in a space that recognizes their identity as a group, much like the tomb of the Scipiones, or, indeed, any Roman atrium that collects the imagines of a family’s ancestors.

AbstractWe prove a duality relation for the moduli of the family of curves connecting two sets and the family of surfaces separating the sets, in the setting of a complete metric space equipped with a doubling measure and supporting a Poincaré inequality. Then we apply this to show that quasiconformal mappings can be characterized by the fact that they quasi-preserve the modulus of certain families of surfaces.

On March 15, 2020, in response to the Covid-19 pandemic, the Honduran government unexpectedly announced a state of emergency and mandated immediate closure of all businesses. Diunsa closed its six stores. The family-owned retailer had anticipated supply chain disruptions, stocked from alternative suppliers, and formed a crisis management team. Now, to keep the business afloat during the unexpected closure and retain all its employees on the payroll, the company had to move sales from the brick-and-mortar stores to an incomplete online retail site. The third generation in the family business—the Faraj siblings, all in their 20’s—led the critical transition online and response to setbacks. As digital-native millennials, they helped improve the website, customer service, operations, and delivery in a short amount of time and using external resources and various technologies. As the situation stabilized, Diunsa’s leadership asked: How will Diunsa build on the momentum for digital transformation and turn its tactical actions into a digital strategy? How can we continue to tap into the leadership of our up-and-coming generation to achieve these goals?

Informing families about the impending or actual death of their relatives is one of the most challenging and complex tasks a physician may face. The following article describes goal setting and provides five roles/recommendations for conducting the encounter with patient families regarding the imminent or actual death of their relatives. Importantly, the encounter should be family-centred, and the physician should be highly attentive to family needs. The following roles should be applied based on family needs and should not be sequential as numbered. The first and basic role is to inform the family at the earliest possible time and as often as possible. The second goal of the physician is to convey to the family that their relative received the needed therapy during his hospitalisation or in the community. The third goal of the physician is to help the family reach acceptance of the death of their relative and leave the hospital having moved beyond anger and bargaining. The fourth goal of the physician during the encounters is to reduce or alleviate guilt by stating that nothing could have changed the course of the disease and that all efforts were made to save the patient. The fifth role of the physician is to try and help the family as a single entity and maintain their unity during this stressful situation. Following these roles/methods will help families in the stressful situation and will create the difference between anger and understanding, rage and compassion, and loss and acceptance.

The present Memoir is based upon, and is in a measure supplementary to that by Pro­fessor Schläfli, “On the Distribution of Surfaces of the Third Order into Species, in reference to the presence or absence of Singular Points, and the reality of their Lines,” Phil. Trans, vol. cliii. (1863) pp. 193—241. But the object of the Memoir is different. I disregard altogether the ultimate division depending on the reality of the lines, attend­ing only to the division into (twenty-two, or as I prefer to reckon it) twenty-three cases depending on the nature of the singularities. And I attend to the question very much on account of the light to be obtained in reference to the theory of Reciprocal Surfaces. The memoir referred to furnishes in fact a store of materials for this purpose, inasmuch as it gives (partially or completely developed) the equations in plane-coordinates of the several cases of cubic surfaces, or, what is the same thing, the equations in point-coor­dinates of the several surfaces (orders 12 to 3) reciprocal to these repectively. I found by examination of the several cases, that an extension was required of Dr. Salmon’s theory of Reciprocal Surfaces in order to make it applicable to the present subject ; and the preceding “Memoir on the Theory of Reciprocal Surfaces” was written in connexion with these investigations on Cubic Surfaces. The latter part of the Memoir is divided into sections headed thus:— “Section I = 12, equation (X, Y, Z, W ) 3 = 0” &c. referring to the several cases of the cubic surface; but the paragraphs are numbered continuously through the Memoir. The twenty-three Cases of Cubic Surfaces—Explanations and Table of Singularities . Article Nos. 1 to 13. 1. I designate as follows the twenty-three cases of cubic surfaces, adding to each of them its equation:

Background. Compliance with referral for out-patient aftercare of psychiatric emergency patients is limited. This study investigated the efficacy of a combination of several referral strategies (fixed appointment, involvement of the family, presence of the aftercare person, motivational counselling) in increasing referral and treatment compliance of patients referred to the psychiatric emergency department of three general hospitals.Methods. A randomized controlled design was used to assess the effect of this experimental condition on referral compliance and on continuation of aftercare treatment.Results. A significant beneficial effect on compliance with the referral was found in two hospitals and a near-significant effect in the third. After 3 months of aftercare, the influence of the experimental procedure on adherence to therapy was still significant in two hospitals, but not in the third.Conclusions. Helping the patient to attend an initial appointment can be achieved by a combination of practical and organizational arrangements.

1. Beginning with a single propositus, who had been previously diagnosed at the age of 10 as suffering from trimethylaminuria (fish-odour syndrome), both her parents and two sisters were investigated biochemically with respect to their ability to N-oxidize trimethylamine (TMA), both when derived from the diet and when administered exogenously. 2. Both the propositus and a second sister were markedly deficient in their ability to N-oxidize TMA, both when derived from the diet and when given as such; furthermore, both siblings readily developed the symptoms of fish-odour syndrome as characterized by a strong objectionable breath and body odour shortly after the oral administration of TMA (300 mg). 3. At this dose level of TMA, neither of the parents nor the third sister showed any evidence of impaired N-oxidation ability nor did they experience any ‘fish-odour’ symptoms. 4. With an oral challenge of 600 mg of TMA, both the parents showed a clear impairment of N-oxidation capacity which was not seen in six healthy unrelated volunteers. Both parents experienced a fish-odour syndrome at this level of TMA challenge. 5. The family data support the hypothesis that trimethylaminuria is an inborn error in the ability to N-oxidize TMA which is inherited as an autosomal recessive trait. Furthermore, experience with this family suggests that an oral challenge dose with 600 mg of TMA may be used to identify carriers of the condition.

A new asellotan isopod of the family Protojaniridae Fresi, Idato & Scipione, 1980 is described from freshwater springs in the Osorno province, Los Lagos region, southern Chile. Wiyufiloides osornoensis gen. & sp. n. is the third South American protojanirid species and the first known groundwater isopod in Chile. The new genus and species is principally characterized by the presence of a vestigial antennal scale, a strongly subchelate pereiopod I and the absence of an apical lobe on the protopod of pleopod II. The new taxon is described in detail and figures are given.
